Built from the ground up in modern Luau with strict type safety, RAC solves the long-standing vulnerability of client-dominated multiplayer game architectures. In traditional Roblox games, developers frequently trust client position, velocity, and hit signals sent over `RemoteEvents`. Malicious actors exploit this trust using client injection tools (such as Dex Explorer, script executors, and memory modifiers) to achieve speed hacks, flight, noclip, reach hacks, remote spam, and godmode. RAC enforces a strict **Zero-Trust Client Security Model**. All physical movement boundaries, combat validations, transaction rates, and player states are verified and adjudicated purely on the server. ``` ┌────────────────────────────────────────────────────────┐ │ ROBLOX SERVER ENGINE │ │ │ │ ┌────────────────────┐ ┌────────────────────┐ │ │ │ DetectionEngine │◄────►│ Heuristics Engine │ │ │ └─────────┬──────────┘ └─────────┬──────────┘ │ │ │ │ │ │ ▼ ▼ │ │ ┌────────────────────┐ ┌────────────────────┐ │ │ │ PunishmentManager │◄────►│ RBAC & Dashboard │ │ │ └─────────┬──────────┘ └─────────┬──────────┘ │ └─────────────┼───────────────────────────┼──────────────┘ │ │ Remote Sync & Cross-Server Live Admin View │ │ ▼ ▼ [ MessagingService / Webhook ] [ Roact Bento UI ] ``` --- ## Core Pillars of RAC ### 1. 100% Server Authoritative Clients never tell the server if an action is valid. The server tracks historical physics frames, raycasts line-of-sight checks against obstacle geometry, audits tool damage cooldowns, and enforces token-bucket limits on all network traffic. ### 2. Multi-Vector Anomaly Correlation Rather than punishing instantly on a single frame jitter, RAC feeds all detector telemetry into a centralized **Luau AI Heuristics Engine**. The heuristics engine correlates spatial anomalies, network ping spikes, and server frame times ($\Delta t$), computing an algorithmic confidence score ($0.0 \dots 1.0$) to guarantee zero false positives. ### 3. Bento-Grid In-Game Admin Dashboard Moderators and administrators access an in-game interface built with **Roact** and styled after modern Bento grids. The dashboard includes a circular risk dial, spatial radar, violation ribbons, live player telemetry, and single-click enforcement actions. ### 4. Cross-Server Distributed Synchronization When an administrator issues a ban or an exploiter triggers high-confidence enforcement, the punishment is immediately broadcast to all active game servers via Roblox `MessagingService` while being permanently recorded into `DataStoreService`. --- ## Why RAC Outperforms Traditional Anti-Cheats | Feature | Legacy Script-Checks | R Anti-Cheat (RAC) | | :--- | :--- | :--- | | **Execution Environment** | Client LocalScripts (easily deleted) | ServerScriptService (inaccessible to clients) | | **False-Positive Prevention** | Hard static cutoffs | Dynamic ping-aware Heuristics Engine | | **Combat Verification** | Client calculates damage | Server verifies reach, raycast LoS, and cooldown | | **Admin Interface** | Legacy chat commands / basic UI | Roact Bento-Grid UI with real-time telemetry | | **Network Protection** | None (crashes on remote spam) | Token-bucket rate limiter & 16KB packet inspection | | **Cross-Server Sync** | Delayed / polling-based | Real-time `MessagingService` broadcast (<50ms) | --- ## Next Steps - Proceed to the [Quick Start Guide](/docs/getting-started/quick-start) to integrate RAC in under 5 minutes. - Learn about the [Prerequisites & API Settings](/docs/getting-started/prerequisites) needed in Roblox Studio. - Review the [System Architecture](/docs/architecture/core-overview) to understand the server lifecycle. -------------------------------------------------------------------------------- DOCUMENT [2]: QUICK START SECTION: Getting Started ROUTE: /docs/getting-started/quick-start BADGE: 5 Mins SUMMARY: Deploy R Anti-Cheat into your Roblox experience in under 5 minutes with zero configuration. -------------------------------------------------------------------------------- ## Overview Getting started with R Anti-Cheat is designed to be seamless. The framework is pre-configured with safe production defaults suitable for most standard Roblox experiences (FPS, RPG, Obby, Simulators). Follow this step-by-step guide to install, verify, and start monitoring your game. --- ## Step 1: Place Files into Your Experience RAC relies on three core folder roots. Copy the respective modules into your project: ``` YourExperience.rbxl ├── ReplicatedStorage │ └── RAC │ ├── Config (config.luau) │ └── Remotes (AdminRemotes, HoneypotRemotes) ├── ServerScriptService │ └── RAC │ ├── Init.server.luau │ ├── Engine.luau │ ├── DetectionEngine.luau │ ├── HeuristicsEngine.luau │ ├── PunishmentManager.luau │ ├── RBACManager.luau │ ├── StorageManager.luau │ ├── DiscordIntegration.luau │ └── Detectors/ (15 modules) └── StarterPlayer └── StarterPlayerScripts └── RAC ├── Client.client.luau └── AdminUI/ (AdminApp.luau, Bento components) ``` --- ## Step 2: Configure Your Owner UserID Open `src/ReplicatedStorage/RAC/Config.luau` and add your Roblox UserID to the `SuperAdmins` or `Admins` list so you can open the Bento Admin Dashboard: ```luau -- ReplicatedStorage/RAC/Config.luau return { -- Admin & Moderation Access SuperAdmins = { [12345678] = true, -- Replace with your Roblox UserID }, Admins = { [87654321] = true, }, -- Default Enforcement Mode: "Monitor", "Kick", or "Ban" EnforcementMode = "Kick", -- Heuristics Confidence Threshold (0.0 to 1.0) AutoEnforceConfidence = 0.85, } ``` --- ## Step 3: Enable Studio API Access In Roblox Studio: 1. Navigate to **Home** > **Game Settings**. 2. Select the **Security** tab on the left. 3. Turn **ON** `Enable Studio Access to API Services`. 4. Turn **ON** `Allow HTTP Requests` (required if using Discord alerts). 5. Click **Save**. --- ## Step 4: Test in Studio Play Mode Press **F5** in Roblox Studio to start Play mode. 1. Open the Developer Console (**F9**). 2. Look for the RAC startup banner: ``` [RAC] Initializing R Anti-Cheat Server Engine v1.0.0... [RAC] Loaded 15 Detection Modules successfully. [RAC] Heuristics Engine running. Heartbeat loop active. [RAC] Ready. Monitoring active sessions. ``` 3. Press **F2** on your keyboard (or click the shield icon in the top-left) to mount and view the **Roact Bento Admin Dashboard**. --- ## Step 5: Verify Detection with a Safe Test To confirm that RAC actively detects exploits without risking a ban, run this test in the Studio Command Bar during Play mode: ```luau -- Simulate client physics speed anomaly local player = game.Players.LocalPlayer if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then player.Character.HumanoidRootPart.CFrame = player.Character.HumanoidRootPart.CFrame + Vector3.new(350, 0, 0) end ``` Observe the console: ``` [RAC:Detection] [Teleport] Player 'Player1' moved 350.0 studs in 0.03s (Max: 28.0 studs). [RAC:Heuristics] Violation score updated for Player1: Confidence 0.94 (High Risk). [RAC:Enforcement] Enforcing rollback / kick on Player1 (Reason: Teleport Exploit). ``` --- ## Next Steps - Explore [Configuration Options](/docs/configuration/config-reference) to fine-tune detector speeds and thresholds. - Learn how the [15 Detection Engines](/docs/detectors/movement) operate under the hood. - Set up [Discord Webhooks](/docs/discord/webhook-integration) to receive instant exploit alerts in your moderation channel. -------------------------------------------------------------------------------- DOCUMENT [3]: PREREQUISITES SECTION: Getting Started ROUTE: /docs/getting-started/prerequisites BADGE: Setup SUMMARY: Roblox Studio settings, engine requirements, and security permissions for running RAC. -------------------------------------------------------------------------------- ## Engine Requirements R Anti-Cheat requires modern Roblox runtime features. Before deploying, ensure your development environment satisfies these requirements: | Requirement | Minimum Supported | Recommended | Notes | | :--- | :--- | :--- | :--- | | **Roblox Studio** | Version 0.600+ | Latest Version | Supports typed Luau features | | **Luau Typechecking** | Strict / Nonstrict | `--!strict` | RAC core is written with strict Luau types | | **DataStore Service** | Standard DataStore | Standard v2 | Used for persistent bans & audit logs | | **MessagingService** | Enabled | Enabled | Required for real-time cross-server sync | | **HttpService** | Enabled (Optional) | Enabled | Only required for Discord webhook alerts | --- ## Studio Security Settings By default, Roblox Studio isolates local test sessions from live backend services. You must enable API access in your experience settings: ### Step 1: Open Game Settings Click the **Game Settings** gear icon in the **Home** tab of the Roblox Studio ribbon bar. If your place has not yet been published, choose **Publish to Roblox** first. ### Step 2: Configure the Security Tab In the left sidebar, click **Security**: 1. **Enable Studio Access to API Services**: Toggle this switch **ON**. This allows `DataStoreService` and `MessagingService` calls to execute within Studio tests. > [!NOTE] > When Studio API access is disabled, RAC automatically switches to an in-memory fallback store (`FallbackStore`), preventing any studio crashes or blocked threads. 2. **Allow HTTP Requests**: Toggle this switch **ON** if you intend to stream violation logs and moderation actions to an external Discord webhook. 3. Click **Save** at the bottom of the dialog. --- ## Third-Party Package Dependencies RAC is designed to have **zero external binary dependencies**. It runs entirely within native Roblox Luau: - **Roact / React-lua**: The Admin Dashboard is built on pure Luau Roact (included in `src/StarterPlayer/StarterPlayerScripts/RAC/AdminUI/Roact.luau`), requiring no npm or external bundler at runtime. - **Rojo (Optional)**: If you use VS Code or Antigravity IDE, Rojo 7.x is recommended for two-way filesystem synchronization. --- ## Next Steps - Follow the [Roblox Studio Setup Guide](/docs/installation/studio-setup) or the [Rojo Workflow Guide](/docs/installation/rojo-workflow) to install RAC. -------------------------------------------------------------------------------- DOCUMENT [4]: COMMERCIAL RELEASE INTEGRATION SECTION: Installation ROUTE: /docs/installation/commercial-distribution BADGE: Buyer Guide SUMMARY: Step-by-step buyer guide for unzipping the R-AntiCheat commercial distribution package and integrating it into Roblox Studio. -------------------------------------------------------------------------------- ## Overview If you purchased or received the official commercial release package (`R-AntiCheat-v1.0.0-COMMERCIAL.zip`), this guide provides instructions for unzipping and integrating RAC into your Roblox game. This edition is exclusively authored and licensed by **[Badhon Vitality](https://github.com/badhonvitality)**. --- ## Package Directory Structure After extracting `R-AntiCheat-v1.0.0-COMMERCIAL.zip`, you will see: ``` R-AntiCheat-v1.0.0-COMMERCIAL/ ├── LICENSE.txt <-- Commercial License Agreement ├── BUYER_INTEGRATION_GUIDE.md <-- Markdown integration instructions ├── default.project.json <-- Rojo project configuration └── src/ ├── ReplicatedStorage/ │ └── RAC/ │ ├── ClientAPI.luau <-- SDK for building your own Admin GUI │ └── Shared/ │ ├── Constants.luau <-- Remote IDs and network topics │ └── Types.luau <-- Typed Luau schemas ├── ServerScriptService/ │ └── RAC/ │ ├── config.luau <-- YOUR CONFIGURATION (Add your UserID here) │ ├── Main.server.luau <-- Server bootstrapper & engine loader │ ├── Core/ <-- Engine, Risk, Evidence, & Punishment managers │ ├── Detectors/ <-- 15 modular detection engines │ ├── Security/ <-- RBAC Permission & Token-bucket rate limiters │ ├── Services/ <-- AI Heuristic Engine, Storage, & Discord services │ └── Admin/ <-- Server RPC handlers & telemetry routers └── StarterPlayer/ └── StarterPlayerScripts/ └── RAC/ └── Client.client.luau <-- Lightweight client adapter (telemetry & warnings) ``` --- ## Step 1: Unzipping & Placing Files in Roblox Studio Open your game in **Roblox Studio**. ### Option A: Manual Explorer Placement 1. In the **Explorer** window, create a folder named `RAC` inside `game.ReplicatedStorage`. Copy the files from `src/ReplicatedStorage/RAC` into it. 2. In `game.ServerScriptService`, create a folder named `RAC`. Copy the contents of `src/ServerScriptService/RAC` into it. Ensure `Main.server.luau` is a **Script** (Server context). 3. In `game.StarterPlayer.StarterPlayerScripts`, create a folder named `RAC`. Copy `Client.client.luau` into it as a **LocalScript**. ### Option B: Rojo Synchronization If your studio workflow uses Rojo, place the extracted package into your project root and start the server: ```bash rojo serve ``` Click **Connect** in the Roblox Studio Rojo plugin to sync the file hierarchy automatically. --- ## Step 2: Configuring Your Owner UserID Open `ServerScriptService/RAC/config.luau`. Locate the `Config.Admin` table and replace `12345678` with your Roblox UserID: ```luau Config.Admin = { Roles = { [12345678] = "Owner", -- Replace with your actual Roblox UserID }, DefaultRole = "Viewer", } ``` --- ## Step 3: Enabling Studio API Permissions For persistent bans and Discord alerts: 1. In Studio, click **Home** > **Game Settings**. 2. Select **Security** in the left sidebar. 3. Turn **ON** `Enable Studio Access to API Services`. 4. Turn **ON** `Allow HTTP Requests` (for Discord alerts). 5. Click **Save**. --- ## Step 4: Testing & Verification 1. Press **F5** in Roblox Studio to start Play mode. 2. Open the Developer Console (**F9**). 3. Verify that the RAC startup banner appears: ``` [RAC] Initializing Framework v1.0.0... [RAC StorageService] Operating in Studio session with low-latency memory store. [RAC] Framework loaded successfully in Studio Test mode. [RAC] Anti-Cheat Framework successfully mounted and armed. [RAC] Client Adapter active. Use ReplicatedStorage.RAC.ClientAPI to power custom Admin Panels. ``` --- ## Step 5: Designing Your Custom Admin GUI The commercial distribution intentionally leaves the presentation layer open so you can design your own custom Admin Panel in your game's unique art style. Require `ReplicatedStorage.RAC.ClientAPI` from any `LocalScript`: ```luau local RACClient = require(game.ReplicatedStorage.RAC.ClientAPI) -- Query live players local ok, players = RACClient.GetLivePlayers() -- Kick a rule-breaker RACClient.PunishPlayer("Kick", targetUserId, targetUsername, "Violated Rules") ``` For complete step-by-step UI tutorials, refer to: - [Building Custom Admin GUIs](/docs/admin-panel/widgets) - [Client API & Remotes Reference](/docs/admin-panel/in-game-moderation) --- ## 🔒 Commercial License & Support This product is commercially licensed and exclusively authored by **[Badhon Vitality](https://github.com/badhonvitality)**. - Official Profile: [https://github.com/badhonvitality](https://github.com/badhonvitality) - Unauthorized redistribution, re-selling, or stripping copyright headers is strictly prohibited and subject to legal prosecution. -------------------------------------------------------------------------------- DOCUMENT [5]: ROBLOX STUDIO SETUP SECTION: Installation ROUTE: /docs/installation/studio-setup BADGE: Studio SUMMARY: Direct installation and setup of R Anti-Cheat directly inside Roblox Studio. -------------------------------------------------------------------------------- ## Overview You can install R Anti-Cheat directly within Roblox Studio without external command-line tools. This guide walks you through importing the source folders, verifying service placements, and starting the engine. --- ## Direct Folder Structure Ensure your Explorer window mirrors the following structure: ``` ReplicatedStorage └── RAC ├── Config └── Remotes (auto-generated if missing) ServerScriptService └── RAC ├── Init.server.luau (Script) ├── Engine.luau (ModuleScript) ├── DetectionEngine.luau (ModuleScript) ├── HeuristicsEngine.luau (ModuleScript) ├── PunishmentManager.luau (ModuleScript) ├── RBACManager.luau (ModuleScript) ├── StorageManager.luau (ModuleScript) ├── DiscordIntegration.luau (ModuleScript) └── Detectors (Folder) ├── SpeedDetector.luau ├── FlyDetector.luau ├── TeleportDetector.luau ├── NoclipDetector.luau ├── JumpDetector.luau ├── CombatReachDetector.luau ├── DamageRateDetector.luau ├── WallbangDetector.luau ├── WalkSpeedTamperDetector.luau ├── GodModeDetector.luau ├── RemoteRateLimiter.luau ├── RemotePayloadInspector.luau ├── EconomyRateDetector.luau ├── InventoryOverflowDetector.luau └── HoneypotDetector.luau StarterPlayer └── StarterPlayerScripts └── RAC ├── Client.client.luau (LocalScript) └── AdminUI ├── Roact.luau ├── AdminApp.luau └── Components ├── DashboardDial.luau ├── SpatialRadar.luau ├── FlowRibbons.luau └── VelocityTrend.luau ``` --- ## Verifying ServerScript Execution In Roblox, scripts in `ServerScriptService` run automatically when the server starts. `Init.server.luau` performs the following automated steps upon boot: 1. **Remote Provisioning**: Checks `ReplicatedStorage.RAC.Remotes`. If `AdminRemote` or honeypots are missing, the server creates secure `RemoteFunction` and `RemoteEvent` instances automatically. 2. **Detector Registration**: Dynamically scans `ServerScriptService.RAC.Detectors` and registers each detector with `DetectionEngine`. 3. **Heartbeat Attachment**: Hooks batched spatial simulation to `RunService.Heartbeat`. 4. **Player Listener Attachment**: Subscribes to `Players.PlayerAdded` and `Players.PlayerRemoving` to manage session records, token buckets, and historical state buffers. --- ## Studio Test Run Press **F5** to start testing. You should see the following logs in your Output window: ``` [RAC:Init] Starting R Anti-Cheat Server Engine... [RAC:Init] Discovered 15 detection modules in Detectors/. [RAC:Storage] Connected to DataStore 'RAC_Punishments_v1'. [RAC:Engine] Attached 15 detectors to RunService.Heartbeat. [RAC:Engine] Server Engine initialized in 4.2ms. ``` If you see these logs, your Studio setup is complete and fully functional. --- ## Next Steps - Want to manage code in Git? See the [Rojo Workflow Guide](/docs/installation/rojo-workflow). - Or review the [Manual Installation Guide](/docs/installation/manual-install) for troubleshooting file paths. -------------------------------------------------------------------------------- DOCUMENT [6]: ROJO WORKFLOW SECTION: Installation ROUTE: /docs/installation/rojo-workflow BADGE: Tooling SUMMARY: Using Rojo to sync R Anti-Cheat from Git and filesystem directly into Roblox Studio. -------------------------------------------------------------------------------- ## Overview For teams using version control (Git, GitHub, GitLab) and external code editors (VS Code, Cursor, Antigravity IDE), **Rojo** allows you to edit RAC source code on disk and have it live-synced into Roblox Studio. --- ## Default Project Configuration (`default.project.json`) Here is the standard `default.project.json` for syncing RAC into an existing experience: ```json { "name": "R-Anti-Cheat", "tree": { "$className": "DataModel", "ReplicatedStorage": { "RAC": { "$path": "src/ReplicatedStorage/RAC" } }, "ServerScriptService": { "RAC": { "$path": "src/ServerScriptService/RAC" } }, "StarterPlayer": { "StarterPlayerScripts": { "RAC": { "$path": "src/StarterPlayer/StarterPlayerScripts/RAC" } } } } } ``` --- ## Starting the Rojo Sync Server 1. Open a terminal in the root directory of your project. 2. Start the Rojo sync server: ```bash rojo serve ``` 3. You should see output indicating that the server is listening: ``` [INFO] Listening on 127.0.0.1:34872 [INFO] Ready to serve project! ``` --- ## Connecting in Roblox Studio 1. Open your place in Roblox Studio. 2. Open the **Rojo** plugin from the **Plugins** tab. 3. Verify the address is `localhost:34872` and click **Connect**. 4. The RAC files will immediately sync into `ReplicatedStorage`, `ServerScriptService`, and `StarterPlayerScripts`. --- ## Building a Standalone Place (`.rbxl`) To build a complete place file from the command line for automated testing or CI/CD pipelines: ```bash rojo build -o RAC_Production.rbxl ``` This generates a deployable `.rbxl` file containing all server scripts, client components, and configuration modules ready for Roblox publishing. --- ## Next Steps - Review the [System Architecture](/docs/architecture/core-overview) to see how modules communicate. - Learn about the [Configuration Reference](/docs/configuration/config-reference) to customize detector parameters. -------------------------------------------------------------------------------- DOCUMENT [7]: MANUAL INSTALLATION SECTION: Installation ROUTE: /docs/installation/manual-install BADGE: Reference SUMMARY: Step-by-step instructions for copying RAC modules and verifying service hierarchies manually. -------------------------------------------------------------------------------- ## Overview If you are merging RAC into a legacy game repository without Rojo or package managers, follow this manual verification checklist to ensure all instances are parented correctly. --- ## Service Hierarchy Checklist Ensure each script and module has the exact ClassName and parent shown below: ### 1. `game.ReplicatedStorage` - [ ] Folder named **RAC** - [ ] ModuleScript named **Config** (`Config.luau`) - [ ] Folder named **Remotes** - [ ] RemoteFunction named **AdminRemote** - [ ] RemoteEvent named **AdminStream** - [ ] RemoteEvent named **ClaimFreeRobux** *(Deceptive Honeypot)* - [ ] RemoteEvent named **Admin_SetLevel** *(Deceptive Honeypot)* - [ ] RemoteEvent named **GiveAllItems** *(Deceptive Honeypot)* ### 2. `game.ServerScriptService` - [ ] Folder named **RAC** - [ ] Script named **Init** (`Init.server.luau` with RunContext = Legacy or Server) - [ ] ModuleScript named **Engine** - [ ] ModuleScript named **DetectionEngine** - [ ] ModuleScript named **HeuristicsEngine** - [ ] ModuleScript named **PunishmentManager** - [ ] ModuleScript named **RBACManager** - [ ] ModuleScript named **StorageManager** - [ ] ModuleScript named **DiscordIntegration** - [ ] Folder named **Detectors** containing all 15 detection modules: - `SpeedDetector` - `FlyDetector` - `TeleportDetector` - `NoclipDetector` - `JumpDetector` - `CombatReachDetector` - `DamageRateDetector` - `WallbangDetector` - `WalkSpeedTamperDetector` - `GodModeDetector` - `RemoteRateLimiter` - `RemotePayloadInspector` - `EconomyRateDetector` - `InventoryOverflowDetector` - `HoneypotDetector` ### 3. `game.StarterPlayer.StarterPlayerScripts` - [ ] Folder named **RAC** - [ ] LocalScript named **Client** (`Client.client.luau`) - [ ] Folder named **AdminUI** - [ ] ModuleScript named **Roact** - [ ] ModuleScript named **AdminApp** - [ ] Folder named **Components** - `DashboardDial` - `SpatialRadar` - `FlowRibbons` - `VelocityTrend` --- ## Verifying Network Integrity Never place any files from `ServerScriptService` into `ReplicatedStorage`. Clients can decompile and read everything inside `ReplicatedStorage`, but they **cannot** see or decompile anything inside `ServerScriptService`. RAC strictly maintains this boundary: only non-sensitive configuration keys, public remote declarations, and client UI components reside in client-accessible locations. --- ## Next Steps - Review [System Overview](/docs/architecture/core-overview) to understand the server execution model. -------------------------------------------------------------------------------- DOCUMENT [8]: SYSTEM OVERVIEW SECTION: Architecture ROUTE: /docs/architecture/core-overview BADGE: Architecture SUMMARY: High-level server-authoritative design and component relationship model of R Anti-Cheat. -------------------------------------------------------------------------------- ## Architectural Philosophy R Anti-Cheat operates on a **Single Authority, Zero-Trust Paradigm**. In Roblox, the network replication layer grants physics ownership of the local player character to the client. This design optimizes responsiveness for legitimate players, but makes it trivial for exploit scripts to overwrite position, velocity, and animation states. RAC does not attempt to restrict memory or inject client-side security hooks that can be bypassed. Instead, RAC runs **100% on the server**, treating the client as an untrusted physics emitter whose incoming state must pass geometric, physical, and temporal validation before being accepted. --- ## High-Level Component Topology ``` ┌─────────────────────────────────────────────────────────────────────────────────┐ │ SERVER-SIDE SUBSYSTEMS │ │ │ │ ┌───────────────────────────────────┐ Telemetry ┌───────────────────┐ │ │ │ 15 Detection Engines │────────────────►│ Heuristics Engine │ │ │ │ (Movement, Combat, State, Network)│ │ (AI Correlation) │ │ │ └─────────────────┬─────────────────┘ └─────────┬─────────┘ │ │ │ Rollback / Clamp │ │ │ ▼ ▼ Confidence │ │ ┌───────────────────────────────────┐ ┌───────────────────┐ │ │ │ Spatial Validator │ │ PunishmentManager │ │ │ │ (Raycasts, Delta Positions) │ │ (Kick, Ban, Mute) │ │ │ └───────────────────────────────────┘ └─────────┬─────────┘ │ │ │ │ └───────────────────────────────────┬───────────────────────────────┼─────────────┘ │ Cross-Server Sync │ Webhook ▼ ▼ [ MessagingService ] [ Discord Webhooks ] ``` --- ## Core Server Subsystems ### 1. `Engine.luau` The central orchestration singleton. `Engine` coordinates initialization, attaches detectors to the `RunService.Heartbeat` loop, creates spatial bounding boxes, and exposes the public server API for external game scripts. ### 2. `DetectionEngine.luau` The registry and coordinator for all 15 detection modules. Every frame or event tick: - Manages per-player violation counters and cooldown decay. - Normalizes telemetry across disparate detectors into unified `ViolationReport` structs. - Routes violation reports directly into `HeuristicsEngine`. ### 3. `HeuristicsEngine.luau` The AI and anomaly evaluation engine. Implemented in pure Luau, this module evaluates incoming reports against known exploit fingerprints (e.g., speed + combat reach + remote burst) while factoring in player network latency and server frame-time variance ($\Delta t$). ### 4. `PunishmentManager.luau` The centralized enforcement authority. Executes warnings, position rollbacks, kicks, temporary bans, and permanent bans. Synchronizes punishments with `DataStoreService` and broadcasts ban events across the entire experience cluster via `MessagingService`. ### 5. `RBACManager.luau` Role-Based Access Control enforcing hierarchical permissions (Viewer, Moderator, Admin, SuperAdmin, Owner). Controls access to in-game moderation tools and sensitive server remotes. ### 6. `StorageManager.luau` Abstraction layer over Roblox `DataStoreService` and `MemoryStoreService`. Handles serialization, exponential backoff retries, and automatic failover to `FallbackStore` when running in Studio without API keys. --- ## Next Steps - Trace the lifecycle of a detection in the [Execution Lifecycle Guide](/docs/architecture/execution-flow). - Learn about the [Client-Server Trust Model](/docs/architecture/client-server-model). -------------------------------------------------------------------------------- DOCUMENT [9]: EXECUTION LIFECYCLE SECTION: Architecture ROUTE: /docs/architecture/execution-flow BADGE: Lifecycle SUMMARY: Step-by-step trace of how initialization, frame detection, heuristic scoring, and punishment execution flow. -------------------------------------------------------------------------------- ## Complete Execution Flow Every frame on the Roblox server follows a deterministic execution pipeline: ``` [Server Boot: Init.server.luau] │ ├─► RBACManager.Init() ───────── Load admin IDs & group roles ├─► StorageManager.Init() ────── Verify DataStores / Fallback ├─► PunishmentManager.Init() ─── Subscribe to MessagingService cross-server topic ├─► HeuristicsEngine.Init() ──── Precompute fingerprint cluster weights └─► DetectionEngine.Init() ───── Load & index 15 detectors in Detectors/ │ ▼ [Heartbeat Loop: 60Hz Server Tick] │ ├─► Step 1: Spatial & Physics Validation (Batched per active player) │ ├─ Measure displacement: Δd = ||pos(t) - pos(t-1)|| │ ├─ Validate Δd <= (MaxSpeed * dt * pingFactor) │ ├─ Raycast Line-of-Sight between old pos and new pos │ └─ Verify ground raycast for Jump / Fly states │ ├─► Step 2: Telemetry Ingestion into HeuristicsEngine │ ├─ Map anomaly into active cluster (e.g., SpeedSuite, KillAll) │ ├─ Compute confidence score: C = Σ(w_i * S_i) * LatencyDampener │ └─ Increment risk dossier │ └─► Step 3: Enforcement Action ├─ If C >= AutoEnforceConfidence (0.85): │ ├─ Apply physical rollback / server clamp │ ├─ Call PunishmentManager.Enforce(player, reason, "Kick") │ ├─ Broadcast to MessagingService (Cross-server sync) │ └─ Dispatch throttled embed to Discord webhook └─ If C < AutoEnforceConfidence: └─ Log telemetry to audit ring-buffer for admin dashboard review ``` --- ## Detailed Step Breakdown ### 1. Spatial & Physics Validation During `RunService.Heartbeat`, `DetectionEngine` iterates through all active player characters. It computes horizontal and vertical displacements from the player's last validated CFrame. If the distance traveled exceeds the maximum permitted allowance (accounting for character WalkSpeed, jumping velocity, and gravity), the detector records an anomaly. ### 2. Physical Rollback (Instant Remediation) Before executing a harsh punishment like a kick or ban, RAC immediately restores the player's CFrame to their last verified safe position (`LastValidCFrame`). This renders noclip and speed hacking ineffective within milliseconds, preventing exploiters from reaching protected areas or capturing flags even before a ban is issued. ### 3. Heuristic Scoring & Threshold Evaluation Rather than banning on the first discrepancy, the heuristic engine calculates an aggregate confidence score. If the player's ping suddenly spiked from 40ms to 900ms (a common Roblox physics packet hitch), the confidence dampener scales down the violation, completely eliminating false positives caused by laggy connections. --- ## Next Steps - Understand the [Client-Server Trust Model](/docs/architecture/client-server-model). - Read the [Movement Detectors Guide](/docs/detectors/movement) to see how speed and fly calculations work. -------------------------------------------------------------------------------- DOCUMENT [10]: CLIENT-SERVER MODEL SECTION: Architecture ROUTE: /docs/architecture/client-server-model BADGE: Security SUMMARY: Zero-trust network boundaries, server authority, and exploit resistance mechanics in RAC. -------------------------------------------------------------------------------- ## The Zero-Trust Client Axiom In Roblox, developers often mistakenly assume: 1. "The client cannot fire a RemoteEvent if the UI button is disabled." 2. "The client cannot move faster than Humanoid.WalkSpeed." 3. "The client cannot damage an enemy that is behind a concrete wall." **All three assumptions are false.** An attacker with an active Luau executor can: - Call any `RemoteEvent:FireServer()` or `RemoteFunction:InvokeServer()` with arbitrary arguments. - Directly overwrite `HumanoidRootPart.CFrame` or `AssemblyLinearVelocity` in memory. - Hook into weapon scripts and bypass raycast logic completely. RAC treats the client environment as compromised from the start. --- ## What the Server Validates vs. What the Client Sends | Action | Client Input (Untrusted) | Server Enforcement (RAC) | | :--- | :--- | :--- | | **Player Walking** | Replicated position & velocity | Validates distance traveled $\le (v_{max} \cdot \Delta t)$. Reverts position on violation. | | **Firing Weapons** | Target player ID & hit position | Server raycasts line of sight. Verifies target is within max weapon reach and weapon cooldown has elapsed. | | **Jumping** | Replicated upward velocity | Checks ground raycast to ensure player was standing on a solid surface before granting upward impulse. | | **Remote Requests** | Packets over Remotes | Token-bucket rate limiter restricts calls to $\le 30$ req/sec. Payloads $> 16\text{ KB}$ are discarded. | | **Character Health** | Replicated Humanoid properties | Server owns `MaxHealth` and `Health`. Client tampering triggers immediate state reversion. | --- ## Honeypot Deception To proactively identify malicious users before they disrupt gameplay, RAC registers deceptive honeypot `RemoteEvents` in `ReplicatedStorage.RAC.Remotes`: - `ClaimFreeRobux` - `Admin_SetLevel` - `GiveAllItems` Legitimate game UI scripts never interact with these remotes. Only exploiters scanning the game tree with Dex Explorer or decompilers will attempt to fire them. Any invocation immediately results in a 1.0 confidence flag and instant permanent ban. --- ## Next Steps - Explore the [Configuration Reference](/docs/configuration/config-reference) to customize parameters for your game. - Review [Deceptive Honeypots](/docs/detectors/honeypot) for details on decoy traps. -------------------------------------------------------------------------------- DOCUMENT [11]: CONFIG.LUAU REFERENCE SECTION: Configuration ROUTE: /docs/configuration/config-reference BADGE: Core SUMMARY: Comprehensive schema reference for every configuration table, parameter, and threshold in R Anti-Cheat. -------------------------------------------------------------------------------- ## Overview All runtime behavior, detector sensitivity, risk scoring thresholds, and enforcement policies are defined in `ServerScriptService/RAC/config.luau`. Because RAC executes on the server, modifying `config.luau` requires no client script updates. --- ## 1. General Settings (`Config.General`) Controls core engine runtime cycles and operational flags. ```luau Config.General = { Enabled = true, -- Master switch for the anti-cheat engine Debug = false, -- Prints verbose telemetry to Developer Console Version = "1.0.0", -- Current engine build version ScanIntervalSeconds = 0.5, -- Frequency of main detection loop (seconds) ServerAuthoritativeOnly = true, -- Reject all client-reported physics assertions } ``` --- ## 2. Anti-False Detection Engine (`Config.AntiFalseDetection`) Protects legitimate players experiencing lag, ping spikes, or physics glitches from receiving unwarranted flags. | Parameter | Type | Default | Description | | :--- | :--- | :--- | :--- | | `ConsecutiveViolationsRequired` | `number` | `2` | Number of consecutive violation ticks required before registering an incident. | | `PingCompensationEnabled` | `boolean` | `true` | Dynamically scales speed and combat tolerances based on player round-trip latency. | | `MaxAcceptablePingSeconds` | `number` | `0.5` | Maximum ping (500ms) considered before dampening violation risk. | | `VehicleExemptionAuto` | `boolean` | `true` | Automatically grants high-speed exemptions while seated in a `VehicleSeat` or `Seat`. | | `RespawnGracePeriodSeconds` | `number` | `3.0` | Inactivity grace window granted immediately upon character respawning. | | `TeleportGracePeriodSeconds` | `number` | `1.5` | Grace window granted after legitimate server-initiated CFrame teleports. | | `FreefallAccelerationTolerance` | `number` | `1.35` | Multiplier for gravity acceleration when evaluating falling player speeds. | --- ## 3. Individual Detector Parameters (`Config.Detectors`) ### Speed (`Config.Detectors.Speed`) - `Enabled` (`boolean`): Toggle speed anomaly monitoring. - `BaseWalkSpeed` (`number`): Standard unbuffed character speed (typically `16`). - `MaxWalkSpeedTolerance` (`number`): Speeds exceeding this value (default `24`) trigger a violation. - `VehicleSpeedMultiplier` (`number`): Permitted velocity scaling when driving (default `5.0`). - `RiskWeight` (`number`): Risk score increment per confirmed violation (default `20`). ### Fly (`Config.Detectors.Fly`) - `MaxAirTimeSeconds` (`number`): Maximum continuous time in airborne state without touching ground (default `2.8s`). - `RaycastFloorDistance` (`number`): Distance downward checked via raycast to detect solid terrain/parts (default `8.0` studs). - `RiskWeight` (`number`): Risk score points added upon flight detection (default `30`). ### Teleport (`Config.Detectors.Teleport`) - `MaxDistancePerSecond` (`number`): Maximum allowable distance moved in 1 second without server authorization (default `50` studs). - `RiskWeight` (`number`): Risk weight points (default `35`). ### Noclip (`Config.Detectors.Noclip`) - `CheckRadius` (`number`): Sphere-cast collision radius surrounding `HumanoidRootPart` (default `1.5` studs). - `IgnoreTransparencyThreshold` (`number`): Parts with transparency $> 0.9$ (decorative glass/portals) are ignored. - `RiskWeight` (`number`): Risk points (default `40`). ### Combat (`Config.Detectors.Combat`) - `MaxMeleeReachStuds` (`number`): Maximum allowable distance between attacker and target for melee tools (default `18` studs). - `MaxRangedReachStuds` (`number`): Maximum bullet reach for firearms (default `500` studs). - `ValidateLineOfSight` (`boolean`): Performs server raycast between attacker and victim to prevent wallbangs. - `MinAttackIntervalSeconds` (`number`): Minimum duration between consecutive attacks (default `0.08s` $\approx 12.5$ hits/sec). - `MaxDamagePerHit` (`number`): Maximum possible damage single hit can inflict (default `150`). ### Network & Remotes (`Config.Detectors.Remote`) - `GlobalRateLimitPerSecond` (`number`): Maximum remote requests allowed per player before rate-limiting (default `35` req/s). - `MaxPayloadSizeBytes` (`number`): Maximum byte size of any inbound remote packet (default `16384` bytes = 16KB). - `DropInvalidCalls` (`boolean`): Automatically drops malformed remote calls with corrupted argument types. --- ## 4. Central Risk Engine (`Config.Risk`) RAC aggregates detector violations into a composite player risk score ($0 \dots 150$). ```luau Config.Risk = { Enabled = true, WarningThreshold = 35, -- Triggers in-game warning notification KickThreshold = 70, -- Triggers automatic kick if AutoKick = true BanThreshold = 100, -- Triggers automatic ban if AutoBan = true DecayRatePerMinute = 5, -- Risk points automatically decayed per minute of clean play MaxRiskScore = 150, -- Hard cap on accumulated risk points } ``` --- ## 5. Punishment Policies (`Config.Punishments`) ```luau Config.Punishments = { Enabled = true, AutoWarning = true, -- Send warning dialogue on reaching 35 risk AutoKick = false, -- Manual review mode by default AutoBan = false, -- Requires manual admin action or 1.0 AI confidence RequireStrongEvidence = true, -- Prevents actions without at least 2 incident logs DefaultTempBanDurationSeconds = 86400, -- 24 hours (1 day) AppealDiscordUrl = "https://discord.gg/your-community", } ``` --- ## Next Steps - Learn about [Tuning Profiles](/docs/configuration/tuning-profiles) for specialized genres (FPS, Obby, RPG). - Review [Movement Detectors](/docs/detectors/movement) to see how speed and fly parameters are calculated. -------------------------------------------------------------------------------- DOCUMENT [12]: TUNING PROFILES SECTION: Configuration ROUTE: /docs/configuration/tuning-profiles BADGE: Guides SUMMARY: Recommended configurations for First-Person Shooters, Obbies, RPGs, and Driving Simulators. -------------------------------------------------------------------------------- ## Overview Different game genres possess distinct physics profiles. An obstacle course (Obby) requires strict vertical jump limits, while a high-speed racing or dash-based fighting game requires higher spatial tolerances. RAC easily adapts to your genre by modifying key thresholds in `config.luau`. --- ## 1. First-Person Shooter (FPS) Profile In competitive shooters, combat integrity and line-of-sight are paramount: ```luau -- Recommended FPS Settings Config.Detectors.Combat.ValidateLineOfSight = true Config.Detectors.Combat.MaxMeleeReachStuds = 10 Config.Detectors.Combat.MaxRangedReachStuds = 800 Config.Detectors.Combat.MinAttackIntervalSeconds = 0.05 -- Supports 20 rps weapons Config.Detectors.Combat.MaxDamagePerHit = 100 -- Strict Noclip & Wallbang validation Config.Detectors.Noclip.CheckRadius = 1.2 Config.Detectors.Speed.MaxWalkSpeedTolerance = 22 ``` --- ## 2. Obstacle Course (Obby & Platformer) Profile Platformers need extremely tight airtime and infinite-jump detection to prevent players from skipping difficult stages: ```luau -- Recommended Obby Settings Config.Detectors.Fly.MaxAirTimeSeconds = 1.4 -- Restrict float/flight exploits Config.Detectors.Fly.RaycastFloorDistance = 6.0 Config.Detectors.Jump.MaxJumpHeight = 8.5 Config.Detectors.Jump.MaxJumpsPerTwoSeconds = 2 -- Prevent infinite jump spam Config.Detectors.Speed.MaxWalkSpeedTolerance = 18 -- Obby standard WalkSpeed is 16 ``` --- ## 3. RPG & Fighting Games Profile Games with dash skills, knockback spells, and teleportation abilities should use relaxed spatial thresholds and rely on RAC's exemption tags: ```luau -- Recommended RPG Settings Config.Detectors.Speed.MaxWalkSpeedTolerance = 36 -- Higher base sprint speeds Config.Detectors.Combat.MaxMeleeReachStuds = 24 -- Greatswords / polearm reach Config.Detectors.Combat.MaxDamagePerHit = 500 -- Enable server transaction tokens for inventory items Config.Detectors.Economy.RequireServerTransactionToken = true ``` --- ## 4. Vehicle & Racing Simulator Profile ```luau -- Recommended Vehicle Settings Config.AntiFalseDetection.VehicleExemptionAuto = true Config.Detectors.Speed.VehicleSpeedMultiplier = 12.0 -- Allows 200+ stud/sec driving Config.AntiFalseDetection.TeleportGracePeriodSeconds = 2.5 ``` --- ## Next Steps - Explore the [Movement Detectors](/docs/detectors/movement) documentation. - Learn how to whitelist custom movement skills in [Vehicles & Custom Movement](/docs/integration/vehicles-and-dashes). -------------------------------------------------------------------------------- DOCUMENT [13]: MOVEMENT DETECTORS SECTION: Detection Engines ROUTE: /docs/detectors/movement BADGE: 5 Modules SUMMARY: Server-authoritative physics, velocity, displacement, collision, and jump trajectory detectors. -------------------------------------------------------------------------------- ## Overview Because Roblox grants client physics authority over character models, movement exploits are the most common cheat vector. RAC counters this using a suite of 5 dedicated server-side movement validators: 1. **`SpeedDetector`**: Horizontal displacement monitor (XZ plane). 2. **`FlyDetector`**: Airtime thresholding and downward floor raycasting. 3. **`TeleportDetector`**: Sudden large-distance positional delta tracker. 4. **`NoclipDetector`**: Continuous spatial raycasting against collidable geometry. 5. **`JumpDetector`**: Vertical velocity spikes and multi-jump counting. --- ## 1. SpeedDetector Monitors horizontal displacement between consecutive server ticks. ### Detection Logic - Isolates movement to the horizontal plane ($\text{XZ}$) to avoid penalizing players for gravity-assisted falls. - Computes measured speed: $$v_{\text{measured}} = \frac{\sqrt{\Delta X^2 + \Delta Z^2}}{\Delta t}$$ - Dynamically calculates the threshold: $$v_{\text{max}} = \max(\text{Humanoid.WalkSpeed}, \text{MaxWalkSpeedTolerance}) + \text{PingBuffer}$$ - If $v_{\text{measured}} > v_{\text{max}}$, a violation is reported. ### Anti-False-Positive Protections - **Seat Exemption**: Automatically skipped if `humanoid.Sit` is `true` or if the player is attached to a `VehicleSeat`. - **Ping Buffering**: Dynamically grants up to $10.0$ studs/s buffer based on the player's round-trip latency (`playerState.ping * 12.0`). --- ## 2. FlyDetector Detects unauthorized levitation, CFrame hovering, and upward velocity injection. ### Detection Logic - On each tick, checks if the player is in the `Freefall` state or airborne. - Casts a downward raycast from `HumanoidRootPart.Position` ($8.0$ studs length) using `Workspace:Raycast` to detect solid terrain or parts beneath the player. - If no floor is hit, increments `playerState.continuousAirTime`. - If airtime exceeds `Config.Detectors.Fly.MaxAirTimeSeconds` (default $2.8\text{s}$), a Flight anomaly is flagged. --- ## 3. TeleportDetector Catches instantaneous jumps across maps, stage skipping, and exploit-driven CFrame overwrites. ### Detection Logic - Calculates total 3D displacement: $$\Delta d = \|\mathbf{p}_t - \mathbf{p}_{t-1}\|$$ - If $\Delta d > (\text{MaxDistancePerSecond} \cdot \Delta t)$, the move is flagged as a teleport. - **Server Teleport Exemption**: When the server legitimately teleports a player via `Engine:TeleportPlayer(player, targetCFrame)`, a `TeleportGracePeriod` tag is granted, preventing false flags. --- ## 4. NoclipDetector Prevents players from passing through walls, security doors, or terrain boundaries. ### Detection Logic - Performs a line raycast between the player's previous verified position ($\mathbf{p}_{t-1}$) and their current position ($\mathbf{p}_t$). - Filters out non-collidable parts (`CanCollide == false`), character accessories, and parts with transparency $> 0.9$ (cosmetic glass or water). - If a solid barrier was crossed without collision, the detector flags Noclip and immediately triggers a position rollback to $\mathbf{p}_{t-1}$. --- ## 5. JumpDetector Prevents infinite jumping, high-jumping, and moon-gravity exploits. ### Detection Logic - Monitors vertical velocity spikes: $$v_Y = \frac{\Delta Y}{\Delta t}$$ - Tracks jump count within a 2-second sliding window (`MaxJumpsPerTwoSeconds = 3`). - If a player initiates an upward jump impulse while already in mid-air (without touching a ladder or truss), Infinite Jump is flagged. --- ## Next Steps - Explore [Combat Detectors](/docs/detectors/combat) for reach and hit validation. - Learn about [Player State Detectors](/docs/detectors/player-state) for WalkSpeed and health tampering. -------------------------------------------------------------------------------- DOCUMENT [14]: COMBAT DETECTORS SECTION: Detection Engines ROUTE: /docs/detectors/combat BADGE: 3 Modules SUMMARY: Server-authoritative attack range, weapon damage rates, fire rate intervals, and line-of-sight validation. -------------------------------------------------------------------------------- ## Overview In multiplayer combat games, exploiters often manipulate weapon scripts to hit enemies from across the map (Reach Hack), shoot through concrete walls (Wallbang Hack), or fire 50 bullets per frame (Rapid Fire / Kill-All). RAC provides 3 server-side combat validators that intercept hit signals before damage is applied to any humanoid: 1. **`ReachValidator`**: Enforces strict spatial boundaries between attacker and target. 2. **`FireRateValidator`**: Enforces minimum time intervals between consecutive attacks. 3. **`WeaponDamageValidator`**: Enforces maximum allowable damage caps and line-of-sight geometry. --- ## 1. ReachValidator (`ReachValidator.luau`) Validates the physical distance between the attacker's weapon origin and the victim's hitbox. ### Validation Formula For any attack event: $$\text{Distance} = \|\mathbf{p}_{\text{attacker}} - \mathbf{p}_{\text{victim}}\|$$ - **Melee Weapons**: Allowed distance $\le 18.0$ studs (configurable via `Config.Detectors.Combat.MaxMeleeReachStuds`). - **Ranged Weapons**: Allowed distance $\le 500.0$ studs (configurable via `Config.Detectors.Combat.MaxRangedReachStuds`). - Dynamic tolerance is granted for moving targets based on the combined relative velocities of both characters. If $\text{Distance} > \text{MaxReach}$, the hit is immediately rejected and zero damage is dealt. --- ## 2. FireRateValidator (`FireRateValidator.luau`) Prevents script executors from bypassing weapon animation cooldowns or auto-clicker spam. ### Cooldown Tracking - The server maintains a timestamp table for each player: `LastAttackTimestamps[userId]`. - When an attack event arrives: $$\Delta t_{\text{attack}} = \text{currentTime} - \text{LastAttackTimestamps}[userId]$$ - If $\Delta t_{\text{attack}} < \text{MinAttackIntervalSeconds}$ (default $0.08\text{s}$), the attack is flagged as a rapid-fire exploit. --- ## 3. WeaponDamageValidator (`WeaponDamageValidator.luau`) Audits the amount of damage requested and performs a server-side Line-of-Sight (LoS) raycast. ### Line-of-Sight Raycasting Before damage is accepted: 1. Origin: Attacker `HumanoidRootPart.Position` (or weapon muzzle). 2. Direction: Vector towards Victim `HumanoidRootPart.Position`. 3. Raycast params: Exclude attacker character, victim character, and non-collidable transparent parts. 4. If the ray intersects a solid wall or obstacle before reaching the victim, the hit is classified as an illegal **Wallbang Exploit**. ### Damage Cap Validation If a client claims to have dealt $5,000$ damage with a standard weapon, RAC checks: $$\text{Damage} \le \text{MaxDamagePerHit} \quad (\text{default: } 150)$$ Attacks exceeding this threshold are clamped to zero and flagged as critical threats. --- ## Integrating Combat Checks into Your Weapons To integrate RAC with your existing weapon scripts, invoke `Engine:ValidateCombatHit`: ```luau -- Server weapon script local RAC = require(game.ServerScriptService.RAC.Engine) local function OnWeaponHit(attacker: Player, victimCharacter: Model, requestedDamage: number) local isValid, reason = RAC:ValidateCombatHit(attacker, victimCharacter, requestedDamage, "Melee") if not isValid then warn(string.format("[Combat Reject] %s hit rejected: %s", attacker.Name, reason)) return end -- Safe to apply damage local victimHumanoid = victimCharacter:FindFirstChildOfClass("Humanoid") if victimHumanoid then victimHumanoid:TakeDamage(requestedDamage) end end ``` --- ## Next Steps - Review [Player State Detectors](/docs/detectors/player-state) for health and WalkSpeed validation. - See the [FPS Integration Guide](/docs/integration/fps-games) for production weapon setups. -------------------------------------------------------------------------------- DOCUMENT [15]: PLAYER STATE DETECTORS SECTION: Detection Engines ROUTE: /docs/detectors/player-state BADGE: 2 Modules SUMMARY: Server-side monitors for Humanoid WalkSpeed, MaxHealth property tampering, and GodMode exploits. -------------------------------------------------------------------------------- ## Overview Exploiters frequently execute scripts that modify internal properties of their character's `Humanoid` instance—such as setting `Humanoid.WalkSpeed = 120` or locking `Humanoid.Health = math.huge`. RAC provides 2 server-side monitors that supervise character properties and damage absorption: 1. **`PropertyTamperDetector`**: Reverts unauthorized changes to WalkSpeed, JumpPower, and MaxHealth. 2. **`GodModeDetector`**: Detects damage cancellation hooks and impossible healing rates. --- ## 1. PropertyTamperDetector (`PropertyTamperDetector.luau`) ### Monitored Properties The server maintains an authoritative baseline for every character: | Property | Authoritative Value | Allowed Variance | Action on Tamper | | :--- | :--- | :--- | :--- | | `Humanoid.WalkSpeed` | `16.0` (or sprint value) | $\pm 2.0$ | Revert property immediately & flag incident | | `Humanoid.JumpPower` | `50.0` (or high-jump value) | $\pm 5.0$ | Clamp back to authoritative power | | `Humanoid.MaxHealth` | `100.0` (or armor buff) | $0.0$ | Revert immediately to server baseline | ### Reversion Mechanism When a client modifies a property locally, Roblox may replicate the change or allow the client to experience desynchronized physics. The `PropertyTamperDetector` compares the current property value against the server-registered baseline on every scan tick: ```luau if math.abs(humanoid.WalkSpeed - authoritativeWalkSpeed) > allowedVariance then -- Immediately revert the property on the server humanoid.WalkSpeed = authoritativeWalkSpeed -- Record tamper report self:ReportTamper(player, "WalkSpeed", humanoid.WalkSpeed, authoritativeWalkSpeed) end ``` --- ## 2. GodModeDetector (`GodModeDetector.luau`) Exploiters often hook into client metatables to suppress `Humanoid.TakeDamage` calls or immediately reset their health to full upon receiving damage. ### Detection Strategies #### Strategy A: Impossible Healing Rates The server tracks health changes over time. If a player heals more than `MaxLegitimateHealingPerSecond` (default $25.0\text{ HP/s}$) without an active medkit or regeneration aura, a GodMode violation is raised. #### Strategy B: Health Value Verification The detector verifies that: - `Health` does not equal `math.huge`, `1.#INF`, or `NaN`. - `Health` never exceeds `Humanoid.MaxHealth`. #### Strategy C: Damage Cancellation Check When the server deals verified damage via `Humanoid:TakeDamage(amount)`, it schedules a follow-up check $0.15\text{s}$ later. If the player's health did not decrease and no valid shield was active, the script is flagged for damage cancellation. --- ## Next Steps - Explore [Network & Remote Detectors](/docs/detectors/network) for packet rate-limiting and payload validation. - Review the [Heuristics Engine](/docs/ai-agent/heuristics-engine) to see how tamper reports are scored. -------------------------------------------------------------------------------- DOCUMENT [16]: NETWORK & REMOTE DETECTORS SECTION: Detection Engines ROUTE: /docs/detectors/network BADGE: 2 Modules SUMMARY: Token-bucket rate limiting, 16KB packet size inspection, and malformed argument rejection. -------------------------------------------------------------------------------- ## Overview Exploits frequently attempt to crash or lag Roblox game servers by flooding `RemoteEvent` instances with thousands of requests per second (Remote Spam) or sending deeply nested tables and gigantic strings (Memory Exhaustion / Crashers). RAC secures all game remotes using two server-side network layers: 1. **`RemoteRateLimiter`**: Token-bucket algorithm enforcing a 35 req/s rate limit per player. 2. **`RemotePayloadValidator`**: 16KB packet size enforcement and argument type checking. --- ## 1. RemoteRateLimiter (`RemoteRateLimiter.luau`) ### Token-Bucket Algorithm Each connected player is allocated a token bucket: - **Bucket Capacity**: $40$ tokens. - **Refill Rate**: $35$ tokens per second. - **Cost per Call**: $1$ token. ``` Incoming Remote Call │ ▼ ┌──────────────────┐ │ Tokens > 0? │ └─────────┬────────┘ YES │ NO ┌─────────────┴─────────────┐ ▼ ▼ [Consume 1 Token] [Reject & Throttle Call] [Execute Handler] [Increment Spam Counter] ``` If a player exhausts their bucket, subsequent calls are dropped silently on the server, preventing server-frame lag. Continued spamming triggers a high-severity incident report. --- ## 2. RemotePayloadValidator (`RemotePayloadValidator.luau`) Inspects inbound remote arguments before passing them to game handlers. ### Key Checks #### 1. Payload Size Cap (16 KB) Calculates the estimated serialized size of strings, tables, and buffer arguments. Any packet exceeding `16,384 bytes` (16 KB) is immediately rejected: ```luau if estimatedPayloadBytes > Config.Detectors.Remote.MaxPayloadSizeBytes then -- Drop payload to protect server RAM warn(string.format("[RAC:Network] Dropped oversized payload (%d bytes) from %s", estimatedPayloadBytes, player.Name)) return false end ``` #### 2. Deep Table Recursion Guard Exploiters can pass self-referential or 100-level deep nested tables that crash standard JSON encoders. The validator enforces a maximum recursion depth of $4$ levels. #### 3. NaN and Inf Number Checks Checks all numeric parameters for `NaN` (Not-a-Number) and `math.huge` values that cause physics NaN propagation and database write errors. --- ## Wrapping Your Game Remotes To protect your own custom remotes with RAC's rate limiter and payload inspector: ```luau -- Server script local RAC = require(game.ServerScriptService.RAC.Engine) local BuyItemRemote = game.ReplicatedStorage.Remotes.BuyItem BuyItemRemote.OnServerEvent:Connect(function(player, itemName, quantity) -- Validate packet with RAC local isAllowed = RAC:AuditRemoteCall(player, "BuyItem", itemName, quantity) if not isAllowed then return end -- Process game logic safely ProcessPurchase(player, itemName, quantity) end) ``` --- ## Next Steps - Explore [Economy & Inventory Detectors](/docs/detectors/economy-instance). - Learn about [Deceptive Honeypots](/docs/detectors/honeypot) to catch remote scanners. -------------------------------------------------------------------------------- DOCUMENT [17]: ECONOMY & INVENTORY SECTION: Detection Engines ROUTE: /docs/detectors/economy-instance BADGE: 2 Modules SUMMARY: Server-side transaction rate limiting, currency validation, tool duplication, and backpack overflow prevention. -------------------------------------------------------------------------------- ## Overview In games featuring trading, shops, currency, or inventory systems, cheaters target remotes to duplicate items, trigger race conditions in shops, or spam thousands of tools into their backpack to lag the server. RAC monitors item lifecycle and currency transactions via: 1. **`EconomyTransactionValidator`**: Enforces transaction cooldowns, limits, and server-generated tokens. 2. **`ToolTamperDetector`**: Audits character `Backpack` contents and halts unauthorized tool replication. --- ## 1. EconomyTransactionValidator (`EconomyTransactionValidator.luau`) ### Key Validations - **Cooldown Verification**: Enforces a minimum interval of $0.5\text{s}$ (`MinTransactionIntervalSeconds`) between consecutive buy/sell/trade requests. This completely eliminates double-spend and race-condition duplication exploits. - **Maximum Amount Cap**: Rejects transactions exceeding `MaxSingleTransactionAmount` (default $1,000,000$ coins/gems) to prevent overflow bugs. - **Server Token Validation**: When `RequireServerTransactionToken = true`, the server generates a one-time cryptographic token (`GUID`) when opening a shop. Purchases must include this valid token; any reused or missing token is immediately discarded. --- ## 2. ToolTamperDetector (`ToolTamperDetector.luau`) Exploiters frequently attempt to spawn unauthorized weapons or copy tools using local injection scripts. ### Key Validations - **Backpack Capacity Cap**: Enforces a strict limit of $50$ items (`MaxBackpackItems`) in `player.Backpack`. Excess items spawned by scripts are instantly deleted on the server. - **Tool Whitelist Auditing**: When configured, the detector checks each `Tool` parented to the player against the game's registered catalog. Unregistered tools are quarantined and logged. - **Rapid Equip / Drop Spam**: Rapidly parenting tools between `Character` and `Backpack` ($>15\text{ cycles/s}$) is intercepted and throttled to prevent physics desyncs. --- ## Next Steps - Explore [Deceptive Honeypots](/docs/detectors/honeypot) to bait malicious remote spies. - Read about the [AI Heuristic Engine](/docs/ai-agent/heuristics-engine). -------------------------------------------------------------------------------- DOCUMENT [18]: DECEPTIVE HONEYPOTS SECTION: Detection Engines ROUTE: /docs/detectors/honeypot BADGE: Traps SUMMARY: Decoy RemoteEvents designed to catch exploiters using Dex Explorer, SimpleSpy, and script decompilers. -------------------------------------------------------------------------------- ## What are Deceptive Honeypots? Exploiters commonly run external introspection tools such as **Dex Explorer** or **SimpleSpy** to inspect all `RemoteEvents` in `ReplicatedStorage`. They scan for remotes with enticing names like "GiveGems", "FreeAdmin", or "SetLevel" and fire them with modified parameters. RAC turns this behavior into an inescapable trap. During server startup, `HoneypotManager` creates realistic decoy remotes in `ReplicatedStorage.RAC.Remotes`: - `ClaimFreeRobux` - `Admin_SetLevel` - `GiveAllItems` ``` Exploiter opens Dex Explorer │ ▼ Sees "ClaimFreeRobux" in ReplicatedStorage.RAC.Remotes │ ▼ Fires Remote: ClaimFreeRobux:FireServer(100000) │ ▼ HoneypotManager interceptor triggers on server │ ├─► Assigns Maximum Risk Score (150 / 150) ├─► Assigns AI Confidence = 1.00 (Definitive Malice) ├─► Issues Instant Permanent Ban & Cross-Server Sync └─► Dispatches Discord Security Alert Embed ``` --- ## Zero False-Positive Guarantee Because **no legitimate UI script or game component ever references or fires these decoy remotes**, any invocation is 100% conclusive proof of an unauthorized client script injection. There is zero possibility of a regular player firing a honeypot through normal gameplay or latency spikes. --- ## Configuring Honeypot Responses In `ServerScriptService/RAC/config.luau`: ```luau Config.Detectors.Honeypot = { Enabled = true, AutoCreateDecoys = true, ImmediateKickOnTrigger = true, -- Set to true for immediate ejection RiskWeight = 75, -- Immediately pushes player into critical risk } ``` --- ## Adding Custom Honeypot Decoys You can easily register custom honeypot remotes to match the theme of your experience: ```luau local RAC = require(game.ServerScriptService.RAC.Engine) -- Register custom trap remotes RAC:RegisterHoneypot("UnlockAllGamepasses") RAC:RegisterHoneypot("Admin_NukeServer") ``` --- ## Next Steps - Explore the [AI Heuristics Architecture](/docs/ai-agent/heuristics-engine). - View the [Exploit Fingerprint Catalog](/docs/ai-agent/fingerprint-catalog). -------------------------------------------------------------------------------- DOCUMENT [19]: HEURISTICS ARCHITECTURE SECTION: AI Heuristic Engine ROUTE: /docs/ai-agent/heuristics-engine BADGE: AI Core SUMMARY: Pure Luau in-engine pattern correlation, multi-vector exploit clustering, and real-time security dossier synthesis. -------------------------------------------------------------------------------- ## Overview Traditional Roblox anti-cheats rely on simplistic binary thresholds: if a player moves $1\text{ stud}$ too fast, they get kicked. This inevitably leads to false positives when players lag or encounter engine physics hitches. R Anti-Cheat incorporates an **In-Game AI-Assisted Heuristics Engine** (`ServerScriptService/RAC/Services/AIAgent.luau`). Built in pure, typed Luau without external API dependencies, it runs directly on the Roblox server to correlate multi-vector incidents, assess confidence scores, evaluate false-positive probability, and generate explainable security intelligence dossiers. ``` Individual Detectors (Speed, Combat, Remotes, State) │ ▼ DetectionEngine Ingestion │ ▼ ┌───────────────────────────────────┐ │ AIAgent.AnalyzePlayer │ │ │ │ 1.

Telemetry Ingestion & Histogram Indexing All active violations within the player's session are indexed into a frequency histogram by detector name and category (`Movement`, `Combat`, `PlayerState`, `Network`). ### 2. Behavioral Fingerprint Correlation The engine evaluates the histogram against pre-trained exploit signatures (such as the *Movement Manipulation Suite* or *Kill-All / Silent Aim Pattern*). If 2 or more related detectors fire within the session window, the cluster matches with high confidence ($85\% \dots 95\%$). ### 3. Latency Dampening If the player's round-trip latency exceeds $350\text{ms}$ (`playerState.ping > 0.350`), the engine flags the incident with `"Medium"` false-positive likelihood and decreases confidence by $20\%$. This ensures players on cellular or unstable connections are never falsely banned. --- ## AI Dossier Schema (`Types.AIAnalysisReport`) Every analysis generates a structured, explainable report accessible to administrators via the Bento Dashboard or API: ```luau export type AIAnalysisReport = { id: string, -- Unique GUID userId: number, -- Player UserID username: string, -- Player Username timestamp: number, -- Unix epoch timestamp overallRisk: "Low" | "Medium" | "High" | "Critical", riskScore: number, -- Normalized 0-150 risk patternSummary: string, -- High-level human-readable summary correlationNotes: string, -- Detailed algorithmic justification confidenceScore: number, -- 0 to 100% confidence suspectedExploitTypes: { string }, -- Matched signature names recommendedAction: "None" | "Monitor" | "Warn" | "Kick" | "TempBan" | "PermBan", falsePositiveLikelihood: "Very Low" | "Low" | "Medium" | "High", detailedAnalysis: string, -- Comprehensive incident breakdown } ``` --- ## Next Steps - View the catalog of exploit signatures in the [Exploit Fingerprint Catalog](/docs/ai-agent/fingerprint-catalog). - Learn about latency dampening in [False-Positive Analysis](/docs/ai-agent/false-positive-analysis). -------------------------------------------------------------------------------- DOCUMENT [20]: EXPLOIT FINGERPRINTS SECTION: AI Heuristic Engine ROUTE: /docs/ai-agent/fingerprint-catalog BADGE: Signatures SUMMARY: Catalog of clustered multi-vector behavioral fingerprints recognized by RAC's Luau AI engine. -------------------------------------------------------------------------------- ## What are Behavioral Fingerprints? Modern script executors inject bundles of scripts that alter multiple game mechanics simultaneously. Rather than viewing a speed violation and a vertical displacement spike in isolation, RAC's AI Engine clusters them into recognizable behavioral signatures. --- ## 1. Movement Manipulation Suite - **Associated Detectors**: `Speed`, `Fly`, `InfiniteJump`, `Noclip` - **Minimum Correlated Triggers**: 2 - **Base Confidence**: 85% - **Assigned Risk**: High - **Default Recommendation**: `TempBan` - **Algorithmic Justification**: Simultaneous horizontal velocity exceeding standard limits and ground detachment without physics support indicates an injected movement suite (e.g. infinite jump + fly + speed bypass). --- ## 2. Kill-All / Silent Aim Pattern - **Associated Detectors**: `ReachValidator`, `FireRateValidator`, `WeaponDamageValidator` - **Minimum Correlated Triggers**: 2 - **Base Confidence**: 92% - **Assigned Risk**: Critical - **Default Recommendation**: `PermBan` - **Algorithmic Justification**: Extremely high damage output paired with impossible reach distances across sub-second attack intervals. Characteristic of "Kill-All" exploits or silent-aim target loops. --- ## 3. Remote Packet Flooding & Tamper - **Associated Detectors**: `RemoteRateLimiter`, `RemotePayloadValidator`, `Honeypot` - **Minimum Correlated Triggers**: 2 - **Base Confidence**: 95% - **Assigned Risk**: Critical - **Default Recommendation**: `PermBan` - **Algorithmic Justification**: Rapid-burst remote invocations exceeding $35\text{ calls/sec}$ combined with malformed table structures or decoy honeypot hits. 100% indicative of external script executors scanning or brute-forcing remotes. --- ## 4. State Tampering & Godmode - **Associated Detectors**: `PropertyTamper`, `GodMode`, `StateAbuse` - **Minimum Correlated Triggers**: 2 - **Base Confidence**: 88% - **Assigned Risk**: High - **Default Recommendation**: `Kick` - **Algorithmic Justification**: Unauthorized modification of character `Humanoid.WalkSpeed` or `MaxHealth` on the server, paired with failure to register verified incoming damage. --- ## Next Steps - Understand how confidence is calibrated in [False-Positive Analysis](/docs/ai-agent/false-positive-analysis). - Tour the [Bento Admin Dashboard](/docs/admin-panel/overview) to view live AI reports. -------------------------------------------------------------------------------- DOCUMENT [21]: FALSE-POSITIVE EVALUATION SECTION: AI Heuristic Engine ROUTE: /docs/ai-agent/false-positive-analysis BADGE: Accuracy SUMMARY: Algorithmic confidence formulas, ping compensation, and server tick variance handling. -------------------------------------------------------------------------------- ## The False-Positive Dilemma in Roblox Roblox's networked physics architecture is subject to frequent network jitters: - A player on a cellular connection experiences a 500ms ping spike, causing their physics packets to arrive in a compressed batch (making it appear as if they moved 40 studs in a fraction of a second). - A player character gets flung by a glitchy physics constraint or moving elevator. - The Roblox server experiences a transient frame drop from 60 FPS to 25 FPS ($\Delta t$ expands from $0.016\text{s}$ to $0.040\text{s}$). If an anti-cheat does not compensate for these real-world conditions, innocent players will be kicked or banned. --- ## 4 Layers of False-Positive Defense ``` Raw Movement / Action Event │ ▼ ┌────────────────────────────────────────────────────────┐ │ Layer 1: Two-Tick Consecutive Requirement │ │ (Isolated 1-frame spikes are ignored) │ └───────────────────────┬────────────────────────────────┘ │ ▼ ┌────────────────────────────────────────────────────────┐ │ Layer 2: Dynamic Ping Buffer Scaling │ │ (+12 studs/s per second of RTT latency) │ └───────────────────────┬────────────────────────────────┘ │ ▼ ┌────────────────────────────────────────────────────────┐ │ Layer 3: Vehicle & Seat Exemption Auto-Tag │ │ (Physics ownership shifts automatically whitelist) │ └───────────────────────┬────────────────────────────────┘ │ ▼ ┌────────────────────────────────────────────────────────┐ │ Layer 4: AI Heuristics Latency Dampener │ │ (Reduces confidence by 20% if ping > 350ms) │ └───────────────────────┬────────────────────────────────┘ │ ▼ Calculated Confidence Score (0 - 100%) Action only executed if Confidence >= 85% ``` --- ## Latency Dampening Implementation In `ServerScriptService/RAC/Services/AIAgent.luau`: ```luau -- Assess False-Positive Likelihood based on latency & ping local falsePositiveLikelihood: "Very Low" | "Low" | "Medium" | "High" = "Low" if playerState.ping > 0.350 then -- High latency player: buffer violations to prevent false bans falsePositiveLikelihood = "Medium" highestConfidence = math.max(40, highestConfidence - 20) table.insert(analysisNotes, string.format( "Notice: High client latency (%.0f ms) detected.

Instead of forcing an inflexible, opinionated pre-baked GUI that clashes with your game's visual design, font choices, or screen layout, RAC separates the **server-authoritative moderation engine** from the **client presentation layer**: ``` ┌────────────────────────────────────────────────────────────────────────┐ │ SERVER: RAC AdminServer │ │ - Authoritative RBAC validation (UserId verification) │ │ - Telemetry collation & live threat scoring │ │ - Direct access to PunishmentManager & DetectionEngine │ └───────────────────────────────────┬────────────────────────────────────┘ │ Remotes: RAC_AdminRequest & RAC_AdminEvent ▼ ┌────────────────────────────────────────────────────────────────────────┐ │ CLIENT SDK: ReplicatedStorage.RAC.ClientAPI │ │ - Typed Luau wrapper for all admin RPCs & live events │ │ - Real-time event hooks (OnDetection, OnWarning) │ └───────────────────────────────────┬────────────────────────────────────┘ │ Developer Hooks ▼ ┌────────────────────────────────────────────────────────────────────────┐ │ DEVELOPER'S CUSTOM ADMIN GUI │ │ Choose any UI framework that matches your game: │ │ • Native Roblox ScreenGui (Frames, TextLabels, ImageButtons) │ │ • Roact / React-lua / Roact-Rodux │ │ • Fusion / Iris ImGui / Custom Canvas │ │ • In-Game Chat Commands (/warn, /kick, /ban, /freeze) │ └────────────────────────────────────────────────────────────────────────┘ ``` --- ## Why Decoupled Admin Panels are Superior 1. **Brand & Art Direction Matching**: Your admin interface can match your game's exact UI theme (cyberpunk, fantasy, minimalist, cartoon, or sci-fi). 2. **Zero Bloat in Game Client**: Regular players never download heavy UI components or assets they don't have permission to see. 3. **Framework Freedom**: Use vanilla Roblox instances, modern reactive UI libraries (Fusion, Roact, React-lua), or custom mobile-optimized interfaces. 4. **Uncompromised Security**: Regardless of what your UI looks like, every single action is verified on the server by `PermissionManager` before execution. Exploiters cannot spoof admin privileges by modifying client UI code. --- ## Client API Overview RAC provides an official client-side SDK located at: ``` game.ReplicatedStorage.RAC.ClientAPI ``` Developers can require this module in any client LocalScript to query live telemetry, inspect active player risks, listen to detection events, and execute punishments with simple, typed Luau calls: ```luau local RACClient = require(game.ReplicatedStorage.RAC.ClientAPI) -- 1. Fetch live system overview local success, stats, userRole = RACClient.GetOverviewData() print(string.format("Logged in as %s. Total players monitored: %d", userRole, stats.totalMonitored)) -- 2. Fetch active players and their threat scores local ok, players = RACClient.GetLivePlayers() for _, p in ipairs(players) do print(string.format("[%s] Risk: %d | Ping: %dms", p.username, p.riskScore, p.ping)) end -- 3.

Overview The `ClientAPI` module (`ReplicatedStorage.RAC.ClientAPI`) provides a typed, developer-friendly interface for building custom administrative GUIs. ```luau local RACClient = require(game.ReplicatedStorage.RAC.ClientAPI) ``` Every method below automatically interfaces with RAC's secure server backend (`AdminServer.luau`), which verifies admin permissions via `PermissionManager` on every call. --- ## Method Index ### 1. `ClientAPI.GetOverviewData()` Fetches high-level security metrics and system status. - **Returns**: `(success: boolean, stats: DashboardStats?, userRole: string?)` - **Stats Schema**: ```luau { totalMonitored: number, -- Total active players suspiciousPlayers: number, -- Players with risk > 20 activeIncidents: number, -- Incidents in recent buffer totalPunishments: number, -- Total bans/kicks issued dataStoreHealthy: boolean, -- DataStore availability flag uptimeSeconds: number, -- Engine uptime in seconds categoryBreakdown: { -- Incident count per category Movement: number, Combat: number, PlayerState: number, Remote: number, Economy: number, Instance: number, Honeypot: number, }, recentDetections: { DetectionIncident }, recentAnalyses: { AIAnalysisReport }, } ``` --- ### 2. `ClientAPI.GetLivePlayers()` Returns an array of all active players in the server with real-time risk scores and connection metrics. - **Returns**: `(success: boolean, players: { PlayerTelemetry }?)` - **PlayerTelemetry Object**: ```luau { userId: number, username: string, displayName: string, joinTime: number, riskScore: number, -- Normalized risk (0 - 150) detectionCount: number, -- Total violations in current session ping: number, -- Round-trip latency in milliseconds position: { X: number, Y: number, Z: number }, isSeated: boolean, -- True if player is seated/driving isExempt: boolean, -- True if active temporary exemption } ``` --- ### 3. `ClientAPI.GetPlayerDetail(userId: number)` Retrieves an in-depth investigation dossier for a specific player. - **Arguments**: - `userId` (`number`): Target Roblox UserID. - **Returns**: `(success: boolean, detail: any)` - Returns incident history, position history, and the full explainable `AIAnalysisReport`. --- ### 4. `ClientAPI.PunishPlayer(punishmentType, targetUserId, targetUsername, reason, durationSeconds)` Authoritatively executes a disciplinary action on a player. - **Arguments**: - `punishmentType`: `"Warning"` | `"Freeze"` | `"Kick"` | `"TempBan"` | `"PermBan"` - `targetUserId` (`number`): Target player UserID. - `targetUsername` (`string`): Target player Username. - `reason` (`string`): Explanatory reason (shown in kick/ban dialogues). - `durationSeconds` (`number?`): Duration in seconds (used for `TempBan`, default: $86,400\text{s}$ / 24h). - **Returns**: `(success: boolean, errorMessage: string?)` --- ### 5. `ClientAPI.UnbanPlayer(targetUserId: number)` Revokes an active ban across all servers via `MessagingService`. - **Arguments**: - `targetUserId` (`number`): UserID to unban. - **Returns**: `(success: boolean, errorMessage: string?)` --- ### 6. `ClientAPI.ToggleDetector(detectorName: string, enabled: boolean)` Enables or disables an individual detector module at runtime without server restarts. - **Arguments**: - `detectorName` (`string`): Module name (e.g. `"SpeedDetector"`, `"FlyDetector"`). - `enabled` (`boolean`): New state. - **Returns**: `(success: boolean, errorMessage: string?)` --- ### 7. `ClientAPI.GetAdminLogs()` Returns the chronological audit log of all administrative actions. - **Returns**: `(success: boolean, logs: { AdminActionRecord }?)` --- ## Event Listeners ### `ClientAPI.OnDetection(callback: (incident) -> ())` Fires whenever any detector reports a verified violation. Use this to render real-time toast alerts or log notifications in your custom UI: ```luau RACClient.OnDetection(function(incident) print(string.format("🚨 Violation: %s on %s (Risk: +%d)", incident.detectorName, incident.username, incident.riskAdded )) end) ``` ### `ClientAPI.OnWarning(callback: (warning) -> ())` Fires when the server issues a warning modal to the local player: ```luau RACClient.OnWarning(function(warningData) print("Warning received from server:", warningData.reason) end) ``` --- ## Next Steps - Follow the implementation tutorial in [Building Custom Admin GUIs](/docs/admin-panel/widgets). - Review [Role-Based Access Control](/docs/permissions/rbac-system). -------------------------------------------------------------------------------- DOCUMENT [25]: ENFORCEMENT ACTIONS SECTION: Punishments & Enforcement ROUTE: /docs/punishments/enforcement-types BADGE: Enforcement SUMMARY: Authoritative server-side management for Warnings, Kicks, Temporary Bans, and Permanent Bans. -------------------------------------------------------------------------------- ## Overview R Anti-Cheat supports 4 tiers of disciplinary enforcement. Each action can be triggered manually by an in-game administrator via the Bento Dashboard or executed autonomously by the server when configured in `config.luau`. ``` [Risk Score >= 35] ──► Tier 1: Warning Modal (Non-punitive notification) [Risk Score >= 70] ──► Tier 2: Server Kick (Immediate disconnection) [Risk Score >= 100] ─► Tier 3: Temporary Ban (24h default DataStore lock) [Critical Exploits] ─► Tier 4: Permanent Ban (Permanent cross-server blacklist) ``` --- ## 1. Warning (`Warn`) - **Impact**: Non-punitive. The player remains connected to the server. - **Trigger**: Accumulated risk score $\ge 35$ (or moderator command). - **Behavior**: An in-game prompt notifies the player that anomalous behavior (such as high-latency displacement or rapid input) was detected, advising them to check their connection. --- ## 2. Server Ejection (`Kick`) - **Impact**: Immediate disconnection from the current server instance. - **Trigger**: Accumulated risk score $\ge 70$ (when `Config.Punishments.AutoKick = true`) or moderator action. - **Behavior**: The server invokes `player:Kick(message)`, providing a standardized explanation: ``` [RAC Security Enforcement] You have been kicked from the server. Reason: Speed / Teleport Anomaly Detected. ``` --- ## 3. Temporary Ban (`TempBan`) - **Impact**: Complete account lockout from all experience places for a specified duration (default: $86,400\text{ seconds}$ = 24 hours). - **Trigger**: Repeated high-severity violations or moderator command. - **Storage**: Written to `DataStoreService` under the key `Ban_{userId}`. - **Automatic Expiration**: When the banned player rejoins after `expiresAt <= os.time()`, the lock is automatically lifted, and the player is admitted into the game. --- ## 4. Permanent Ban (`PermBan`) - **Impact**: Irrevocable blacklist across all servers in the experience. - **Trigger**: Honeypot triggers, confirmed multi-vector exploit clustering, or manual SuperAdmin/Owner command. - **Synchronization**: Broadcast immediately to all active servers via `MessagingService:PublishAsync`, causing any active sessions to terminate within milliseconds. --- ## Next Steps - Learn how bans propagate instantly across your cluster in [Cross-Server Synchronization](/docs/punishments/cross-server-sync). - Review [Appeals & Revocations](/docs/punishments/appeals). -------------------------------------------------------------------------------- DOCUMENT [26]: CROSS-SERVER SYNC SECTION: Punishments & Enforcement ROUTE: /docs/punishments/cross-server-sync BADGE: Networking SUMMARY: Real-time cluster synchronization via Roblox MessagingService for instantaneous network-wide bans. -------------------------------------------------------------------------------- ## The Cross-Server Banning Challenge In large Roblox games with dozens or hundreds of concurrent server instances, an exploiter banned in Server A might immediately rejoin Server B if the system relies solely on asynchronous DataStore polling. RAC solves this by implementing **Distributed Messaging Synchronization** using native Roblox `MessagingService`. ``` [Server 1: Admin executes PermBan] │ ├─► 1. Writes BanRecord to DataStoreService (Permanent) │ └─► 2. Publishes to MessagingService topic "RAC_CrossServer_Ban" │ ┌────────────────────┴────────────────────┐ ▼ ▼ [Server 2: Subscribed Listener] [Server 3: Subscribed Listener] - Checks if target player is online - Checks if target player is online - If online: player:Kick(...) - If online: player:Kick(...) - Updates local activeBans memory cache - Updates local activeBans memory cache ``` --- ## Subscribed Topics (`Constants.TOPICS`) `PunishmentManager.Init()` registers two global communication channels: ### 1. `CROSS_SERVER_BAN` (`"RAC_CrossServer_Ban"`) When a ban is published: - Every active game server receives the `Types.PunishmentRecord` payload. - The server checks if `Players:GetPlayerByUserId(record.userId)` is currently present. - If present, the target is immediately kicked: ```luau targetPlayer:Kick(string.format( "\n[RAC Security Enforcement]\nYou have been banned: %s\nAppeal at: %s", record.reason, appealUrl )) ``` - The record is added to the server's in-memory `activeBans` table to reject any rejoin attempts during that server's lifetime. ### 2. `CROSS_SERVER_UNBAN` (`"RAC_CrossServer_Unban"`) When an administrator revokes a ban or accepts an appeal: - An unban event containing `userId` is published. - All game servers purge `activeBans[userId]`, immediately allowing the player to enter game instances without waiting for server restarts. --- ## Performance & Latency Across Roblox's global data center network, `MessagingService` ban propagation typically executes in **$<50\text{ms}$**. An exploiter cannot escape to another server before the ban is registered cluster-wide. --- ## Next Steps - Learn about [Appeals & Revocations](/docs/punishments/appeals). - Review [RBAC Authority](/docs/permissions/rbac-system) to configure who can issue bans. -------------------------------------------------------------------------------- DOCUMENT [27]: APPEALS & REVOCATIONS SECTION: Punishments & Enforcement ROUTE: /docs/punishments/appeals BADGE: Appeals SUMMARY: Configuring community appeal links, unbanning players, and managing moderation accountability. -------------------------------------------------------------------------------- ## Overview Transparency and accountability are essential for player retention. When an automated or manual ban is enforced, RAC includes a direct appeal link in the kick dialogue. --- ## Configuring Appeal URLs In `ServerScriptService/RAC/config.luau`: ```luau Config.Punishments = { -- Discord or web portal where players can submit an appeal ticket AppealDiscordUrl = "https://discord.gg/your-roblox-community", } ``` When a banned player attempts to connect, Roblox displays: ``` Disconnected: [RAC Security Enforcement] You have been banned from this experience. Reason: Malicious Remote Packet Flooding Appeal at: https://discord.gg/your-roblox-community ``` --- ## Revoking Bans (Unbanning Players) Administrators have two convenient ways to revoke a ban: ### Method 1: Using the Bento Admin Dashboard 1. Open the dashboard (**F4** or `/rac`). 2. Navigate to **Punishments** (`PunishmentCenterView`). 3. Locate the player by Username or UserID in the **Active Bans** list. 4. Click **Revoke Ban**. 5. The dashboard confirms the action, removes the entry from `DataStoreService`, and broadcasts the unban across all servers. ### Method 2: Server Command / Script API Call `PunishmentManager.RevokeBan`: ```luau local RAC = require(game.ServerScriptService.RAC.Engine) local punishmentManager = RAC:GetPunishmentManager() -- Revoke ban for UserID 12345678 punishmentManager.RevokeBan(12345678, "Appeal accepted by Lead Moderator") ``` --- ## Next Steps - Explore [RBAC System & Roles](/docs/permissions/rbac-system) to configure moderator access levels. - Review [Discord Webhook Integration](/docs/discord/webhook-integration). -------------------------------------------------------------------------------- DOCUMENT [28]: RBAC AUTHORITY SECTION: Permissions & RBAC ROUTE: /docs/permissions/rbac-system BADGE: RBAC SUMMARY: Server-enforced role hierarchy and permission checks gating in-game admin tools. -------------------------------------------------------------------------------- ## Overview Security inside an administrative dashboard is as critical as catching exploiters. If an unauthorized player could invoke admin remotes to kick other players or wipe ban records, the security of the game would be broken. RAC implements **Role-Based Access Control** via `ServerScriptService/RAC/Security/PermissionManager.luau`. Every incoming action over `AdminRemote` is validated against the player's server-verified Roblox `UserId`. --- ## Role Assignment in `config.luau` Administrators are mapped directly by UserID: ```luau Config.Admin = { Roles = { [727289569] = "Owner", -- Full system control & unbanning [12345678] = "SuperAdmin", -- Server tuning & permanent bans [23456789] = "Admin", -- Kicks, temp bans, config inspection [34567890] = "Moderator", -- Warnings, spectating, freeze }, DefaultRole = "Viewer", -- Unlisted players have read-only or no access } ``` > [!TIP] > During **Roblox Studio** test runs, `PermissionManager` automatically grants the local developer the **Owner** role (`RunService:IsStudio() == true`), enabling instant testing without manual ID configuration. --- ## Permission Gate Checks Before executing any administrative action, the server verifies that the caller's role level satisfies the requirement: ```luau function AdminServer:HandleKickRequest(moderator: Player, targetUserId: number, reason: string) -- Verify moderator has permission to kick if not PermissionManager.CanExecute(moderator, "KICK_PLAYER") then warn(string.format("[Security Alert] Unauthorized kick attempt by %s", moderator.Name)) return false, "Insufficient permissions" end -- Execute kick return PunishmentManager.KickPlayer(targetUserId, reason) end ``` --- ## Next Steps - Explore the complete permissions matrix in [Roles & Levels Reference](/docs/permissions/roles-and-levels). - Learn about [Discord Webhooks](/docs/discord/webhook-integration). -------------------------------------------------------------------------------- DOCUMENT [29]: ROLES & LEVELS SECTION: Permissions & RBAC ROUTE: /docs/permissions/roles-and-levels BADGE: Matrix SUMMARY: Hierarchical permissions matrix across Viewer, Moderator, Admin, SuperAdmin, and Owner roles. -------------------------------------------------------------------------------- ## Role Hierarchy RAC categorizes administrative authority into 5 ascending privilege levels: | Level | Role Name | Primary Responsibility | | :---: | :--- | :--- | | **1** | `Viewer` | Read-only inspection of telemetry, detection feeds, and live metrics.

" is authorized to moderate.") end ``` --- ## Next Steps - Explore [Discord Webhook Integration](/docs/discord/webhook-integration). - Learn about [DataStore & Storage Architecture](/docs/storage/datastore-integration). -------------------------------------------------------------------------------- DOCUMENT [30]: DISCORD WEBHOOK INTEGRATION SECTION: Integrations ROUTE: /docs/discord/webhook-integration BADGE: Integration SUMMARY: Server-side throttled embeds, security alerts, moderation logs, and rate-limit queue management. -------------------------------------------------------------------------------- ## Overview R Anti-Cheat can forward critical security incidents and administrative moderation actions directly to a staff Discord channel. To protect your server from HTTP throttling and Discord API rate limits, `DiscordService.luau` incorporates an **asynchronous FIFO queue**, automatic `@everyone` mention sanitization, and a minimum 2-second rate-limiting throttle between outbound posts. ``` Security Incident Triggered │ ▼ DiscordService.SendDetectionAlert(...) │ ▼ [ Sanitize @everyone / @here ] │ ▼ [ Enqueue into messageQueue ] │ ▼ [ Asynchronous Worker ] (Ensures >= 2.0s between HTTP calls) │ ▼ HttpService:PostAsync(...) │ ▼ [ Formatted Discord Embed ] ``` --- ## Configuration In `ServerScriptService/RAC/config.luau`: ```luau Config.Discord = { Enabled = true, WebhookURL = "https://discord.com/api/webhooks/123456789/your-webhook-token", DetectionAlerts = true, -- Stream high-confidence cheat alerts HighRiskAlerts = true, -- Alert when player enters High/Critical risk WarningAlerts = true, -- Log in-game warnings KickAlerts = true, -- Log player kicks BanAlerts = true, -- Log permanent and temporary bans RateLimitPerMinute = 30, -- Maximum webhook dispatches per minute } ``` > [!IMPORTANT] > Ensure **Allow HTTP Requests** is enabled in Roblox Studio **Game Settings** > **Security**, otherwise `HttpService` will reject outbound requests. --- ## Embed Color Palette & Types Outbound embeds are dynamically color-coded to allow moderators to assess urgency at a glance: | Alert Level | Color Hex | Color Preview | Description | | :--- | :---: | :---: | :--- | | **Critical** | `#EF4444` | 🔴 Red | Honeypots, Kill-All scripts, verified script injections. | | **High** | `#F97316` | 🟠 Orange | Movement manipulation suites, speed & flight clustering. | | **Medium** | `#EAB308` | 🟡 Yellow | Repeated unverified anomalies or damage spikes. | | **Punishment** | `#8B5CF6` | 🟣 Purple | Kick and Ban moderation action receipts. | --- ## Mention Sanitization Security Exploiters frequently attempt to include `@everyone` or `@here` strings in their player display names to trigger mass pings in staff Discord channels. RAC's `sanitize` function injects a zero-width space (`\xE2\x80\x8B`) into every mention string before constructing the JSON payload, neutralizing the exploit while preserving readability. --- ## Next Steps - Explore [DataStore & Storage Architecture](/docs/storage/datastore-integration). - Review [Engine Server API](/docs/api-reference/engine-api). -------------------------------------------------------------------------------- DOCUMENT [31]: DATASTORE & PERSISTENT STORAGE SECTION: Integrations ROUTE: /docs/storage/datastore-integration BADGE: Storage SUMMARY: Roblox DataStoreService integration, schema definitions, retry policies, and low-latency Studio fallback. -------------------------------------------------------------------------------- ## Overview Security states (such as active bans, incident evidence dossiers, and administrative audit trails) must persist reliably across server restarts and place updates. `StorageService.luau` abstracts persistent storage, handling serialization, exponential backoff retries, and seamless fail-safe switching when Roblox APIs are unavailable. ``` Write Operation (SaveBan / SaveIncident) │ ▼ RunService:IsStudio()? ├── YES ──► Write to localMemoryBans (Zero latency, no API limits) └── NO ──► Execute pcall DataStoreService:UpdateAsync / SetAsync │ ├── Success: Return true └── Failure: Retry with exponential backoff & log warning ``` --- ## DataStore Schema Definitions RAC registers 3 isolated DataStores to maintain clean separation of concerns: ### 1. Bans DataStore (`RAC_Bans_v1`) Key: `tostring(userId)` Payload: ```json { "id": "uuid-v4-string", "userId": 12345678, "username": "ExploitPlayer1", "punishmentType": "PermBan", "reason": "Deceptive Honeypot Trigger", "evidence": "Fired ClaimFreeRobux remote at tick 1420", "issuedAt": 1718000000, "expiresAt": null, "issuedBy": "RAC AI Engine", "active": true } ``` ### 2. Incidents DataStore (`RAC_Incidents_v1`) Stores serialized telemetry dossiers for high-risk and critical incidents, preserving player speed, coordinates, ping, and matched signatures for subsequent review. ### 3. Audit Trail DataStore (`RAC_AuditLog_v1`) Chronological record of every administrative action, including moderator UserID, target player, and timestamp. --- ## Studio Memory Fallback Mode Testing anti-cheat code in Roblox Studio can be frustrating when `DataStoreService` throws permission errors or rate-limit warnings. RAC solves this automatically: - When running in Studio (`RunService:IsStudio() == true`), `StorageService` routes all reads and writes to an internal in-memory cache (`localMemoryBans`). - Testing bans, unbans, and incidents requires zero DataStore API setup and executes with zero network latency. - In production live game servers, RAC connects to Roblox's distributed cloud DataStores. --- ## Configuration In `ServerScriptService/RAC/config.luau`: ```luau Config.Storage = { Enabled = true, SaveIncidents = true, SaveBans = true, SaveAdminActions = true, MaxCachedIncidents = 100, AutoSaveIntervalSeconds = 60, } ``` --- ## Next Steps - Explore the [Engine Server API](/docs/api-reference/engine-api) to interact with RAC via code. - Review [Detection Engine API](/docs/api-reference/detection-engine-api). -------------------------------------------------------------------------------- DOCUMENT [32]: ENGINE SERVER API SECTION: Developer API Reference ROUTE: /docs/api-reference/engine-api BADGE: Core API SUMMARY: Comprehensive API reference for Engine.luau public methods, exemptions, hits, and transactions. -------------------------------------------------------------------------------- ## Overview The `Engine` singleton (`ServerScriptService/RAC/Core/Engine.luau`) serves as the primary gateway for integrating RAC into custom game mechanics, weapons, and shops. To consume the API in your server scripts: ```luau local RAC = require(game.ServerScriptService.RAC.Core.Engine) ``` --- ## Method Index ### State & Telemetry #### `Engine:GetPlayerState(player: Player): Types.PlayerMonitoringState?` Returns the active monitoring record for a connected player, including ping, airtime, and risk score. #### `Engine:GetRiskScore(player: Player): number` Returns the normalized risk score ($0 \dots 150$) for the specified player. #### `Engine:GetPlayerIncidents(player: Player): { Types.DetectionIncident }` Returns the complete list of violation incidents recorded for the player in the current session. #### `Engine:GetUptime(): number` Returns the elapsed runtime in seconds since the RAC server engine initialized. --- ### Movement Exemptions #### `Engine:AddExemption(player: Player, reason: string, durationSeconds: number)` Temporarily exempts a player from movement detectors. Use this when applying server-driven velocity boosts, dashes, knockback effects, or cutscene teleports. ```luau -- Dash skill example local function OnPlayerDash(player: Player) -- Grant a 1.5-second movement exemption for the dash RAC:AddExemption(player, "DashSkill", 1.5) -- Apply velocity impulse local rootPart = player.Character.HumanoidRootPart rootPart.AssemblyLinearVelocity = rootPart.CFrame.LookVector * 120 end ``` #### `Engine:RemoveExemption(player: Player, reason: string?)` Revokes an active exemption immediately. If `reason` is omitted, all active exemptions for the player are cleared. --- ### Combat & Economy Validation #### `Engine:ValidateHit(attacker: Player, targetCharacter: Model, claimedDamage: number, weaponType: string?): (boolean, number)` Validates that an attack respects reach boundaries, attack cooldowns, line-of-sight geometry, and damage caps. - **Returns**: `(isValid: boolean, approvedDamage: number)`. If invalid, `isValid` is `false` and `approvedDamage` is `0`. ```luau local isValid, approvedDamage = RAC:ValidateHit(attacker, victimChar, 75, "Rifle") if isValid then victimHumanoid:TakeDamage(approvedDamage) end ``` #### `Engine:ValidateTransaction(player: Player, amount: number, transactionType: string): boolean` Validates that an economy purchase or trade satisfies transaction frequency limits and value caps. --- ### Disciplinary Enforcement #### `Engine:WarnPlayer(player: Player, reason: string, issuerName: string?)` Sends an in-game warning dialogue to the specified player. #### `Engine:KickPlayer(player: Player, reason: string, issuerName: string?)` Disconnects the player from the current server instance. #### `Engine:BanPlayer(userId: number, username: string, reason: string, durationSeconds: number?, issuerName: string?)` Bans the player account across all game servers. If `durationSeconds` is omitted or `nil`, the ban is permanent. #### `Engine:UnbanPlayer(userId: number, issuerName: string?)` Lifts an active ban and broadcasts the revocation across all servers via `MessagingService`. --- ## Next Steps - Review the [Detection Engine API](/docs/api-reference/detection-engine-api). - Learn about [BindableFunction APIs](/docs/api-reference/bindable-functions). -------------------------------------------------------------------------------- DOCUMENT [33]: DETECTION ENGINE API SECTION: Developer API Reference ROUTE: /docs/api-reference/detection-engine-api BADGE: Engine API SUMMARY: Reporting custom violations, querying violation counters, and registering detector telemetry. -------------------------------------------------------------------------------- ## Overview The `DetectionEngine` module (`ServerScriptService/RAC/Core/DetectionEngine.luau`) coordinates incident reporting across all 15 detectors and manages per-player incident dossiers. --- ## Method Index ### `DetectionEngine.RegisterIncident(player: Player, incident: Types.IncidentReport)` Submits a violation report from a detector or game script: ```luau local DetectionEngine = require(game.ServerScriptService.RAC.Core.DetectionEngine) DetectionEngine.RegisterIncident(player, { detectorName = "CustomZoneDetector", category = "Movement", severity = "High", confidence = 0.90, evidence = "Entered restricted VIP boundary without pass.", metadata = { zoneId = "VIP_Vault", attemptedCFrame = tostring(player.Character.HumanoidRootPart.CFrame), }, }) ``` --- ### `DetectionEngine.GetConsecutiveViolations(userId: number, detectorName: string): number` Returns the count of consecutive ticks that the player has violated the specified detector without a clean tick. --- ### `DetectionEngine.ClearPlayerCounters(userId: number)` Resets all violation counters and consecutive anomaly trackers for the specified player (called automatically upon player disconnection). --- ## Next Steps - Explore [BindableFunction API](/docs/api-reference/bindable-functions). - Learn how to build [Custom Detectors](/docs/customization/custom-detectors). -------------------------------------------------------------------------------- DOCUMENT [34]: BINDABLEFUNCTION API SECTION: Developer API Reference ROUTE: /docs/api-reference/bindable-functions BADGE: Decoupled SUMMARY: Decoupled server communication via ServerScriptService.RAC_API for third-party scripts. -------------------------------------------------------------------------------- ## Overview If your game architecture uses microservices or third-party frameworks (such as Knit, AGF, or legacy scripts) that cannot easily `require` RAC's internal ModuleScripts, RAC exposes a decoupled **BindableFunction API** located at: ``` game.ServerScriptService.RAC_API ``` --- ## Supported Commands Invoke `RAC_API:Invoke(command: string, ...)`: ```luau local RAC_API = game.ServerScriptService:WaitForChild("RAC_API") :: BindableFunction ``` ### 1. `ValidateHit` ```luau local isValid, approvedDamage = RAC_API:Invoke("ValidateHit", attacker, targetChar, 50, "Melee") ``` ### 2. `AddExemption` ```luau RAC_API:Invoke("AddExemption", player, "GrappleHookSkill", 2.0) ``` ### 3. `GetRiskScore` ```luau local riskScore = RAC_API:Invoke("GetRiskScore", player) ``` ### 4. `BanPlayer` ```luau RAC_API:Invoke("BanPlayer", targetUserId, "SpeedExploit1", "Flying in lobby", 86400, "Automated Moderator") ``` --- ## Next Steps - Check out the [Game Integration Guides](/docs/integration/fps-games). - Learn about [Creating Custom Detectors](/docs/customization/custom-detectors). -------------------------------------------------------------------------------- DOCUMENT [35]: FPS & SHOOTER GAMES SECTION: Game Integration Guides ROUTE: /docs/integration/fps-games BADGE: FPS SUMMARY: Step-by-step integration for First-Person Shooters: Raycasting line-of-sight, fire rate caps, and bullet reach. -------------------------------------------------------------------------------- ## Overview Competitive First-Person Shooters on Roblox are prime targets for silent aim, wallbangs, and rapid-fire exploits. Integrating RAC into your firearm damage pipeline ensures that every bullet trajectory and hit is validated by the server before any humanoid takes damage. --- ## The Secure Gun Damage Pipeline In an insecure gun system, the client sends a `RemoteEvent` stating: *"I shot player X in the head for 100 damage at position (0, 50, 0)"*. With RAC, the server validates: 1. Is the target actually within the weapon's effective range? 2. Did enough time elapse since the last shot? 3. Is there a concrete wall or obstacle between the shooter and the victim? ```luau -- ServerScriptService/WeaponServer.luau local RAC = require(game.ServerScriptService.RAC.Core.Engine) local FireWeaponRemote = game.ReplicatedStorage.Remotes.FireWeapon FireWeaponRemote.OnServerEvent:Connect(function(player: Player, victimCharacter: Model, hitPart: BasePart) if not victimCharacter or not victimCharacter:IsA("Model") then return end local victimHumanoid = victimCharacter:FindFirstChildOfClass("Humanoid") if not victimHumanoid or victimHumanoid.Health <= 0 then return end -- 1.

Validate hit via RAC local isValid, approvedDamage = RAC:ValidateHit(player, victimCharacter, claimedDamage, "Rifle") if not isValid then -- Exploit attempt: Hit rejected by server return end -- 3. Apply validated damage victimHumanoid:TakeDamage(approvedDamage) end) ``` --- ## Recommended FPS Settings Update `ServerScriptService/RAC/config.luau`: ```luau Config.Detectors.Combat.MaxRangedReachStuds = 600 Config.Detectors.Combat.ValidateLineOfSight = true Config.Detectors.Combat.MinAttackIntervalSeconds = 0.06 -- ~16 shots/second max Config.Detectors.Combat.MaxDamagePerHit = 150 ``` --- ## Next Steps - Explore [RPG & Fighting Games Integration](/docs/integration/rpg-and-pvp). - Review [Combat Detectors](/docs/detectors/combat). -------------------------------------------------------------------------------- DOCUMENT [36]: RPG & FIGHTING GAMES SECTION: Game Integration Guides ROUTE: /docs/integration/rpg-and-pvp BADGE: RPG & PvP SUMMARY: Melee reach validation, combo cooldowns, knockback impulses, and currency transaction safety. -------------------------------------------------------------------------------- ## Overview Role-Playing Games and PvP fighting games combine close-quarters sword combat, abilities, spells, and currency transactions. RAC ensures combat fairness while supporting fast-paced action. --- ## Melee Attack Validation Example ```luau -- Server melee skill script local RAC = require(game.ServerScriptService.RAC.Core.Engine) local MeleeSwingRemote = game.ReplicatedStorage.Remotes.MeleeSwing MeleeSwingRemote.OnServerEvent:Connect(function(attacker: Player, targetModel: Model) local targetHumanoid = targetModel:FindFirstChildOfClass("Humanoid") if not targetHumanoid then return end -- Validate melee swing (Max reach 18 studs) local isValid, approvedDamage = RAC:ValidateHit(attacker, targetModel, 45, "Melee") if not isValid then return end targetHumanoid:TakeDamage(approvedDamage) end) ``` --- ## Knockback & Spell Exemption Handling Spells or heavy sword strikes that fling an opponent through the air can cause RAC's `SpeedDetector` or `FlyDetector` to trigger on the victim. To prevent this, grant a brief **Exemption** to the victim when applying knockback: ```luau local function ApplyKnockback(victimPlayer: Player, direction: Vector3, force: number) -- Grant a 1.2-second exemption for the physics impulse RAC:AddExemption(victimPlayer, "SpellKnockback", 1.2) local root = victimPlayer.Character and victimPlayer.Character:FindFirstChild("HumanoidRootPart") if root then root.AssemblyLinearVelocity = direction.Unit * force end end ``` --- ## Next Steps - Explore [Obby & Platformers Integration](/docs/integration/obby-platformer). - Learn about [Vehicles & Custom Movement](/docs/integration/vehicles-and-dashes). -------------------------------------------------------------------------------- DOCUMENT [37]: OBBY & PLATFORMERS SECTION: Game Integration Guides ROUTE: /docs/integration/obby-platformer BADGE: Obby SUMMARY: Tightening flight thresholds, infinite jump prevention, stage skip detection, and checkpoint rollbacks. -------------------------------------------------------------------------------- ## Overview In obstacle courses (Obbies) and parkour platformers, cheats like Infinite Jump, Fly, and Noclip ruin the challenge and leaderboards by allowing exploiters to skip directly to the final stage. RAC provides dedicated features to protect platforming integrity. --- ## Hardened Obby Configuration In `ServerScriptService/RAC/config.luau`: ```luau -- Tight airtime ceiling: normal jumps take ~0.7-1.0s Config.Detectors.Fly.MaxAirTimeSeconds = 1.3 Config.Detectors.Fly.RaycastFloorDistance = 6.0 -- Restrict jump power and multi-jumps Config.Detectors.Jump.MaxJumpHeight = 7.5 Config.Detectors.Jump.MaxJumpsPerTwoSeconds = 2 -- Strict speed and noclip Config.Detectors.Speed.MaxWalkSpeedTolerance = 17.5 Config.Detectors.Noclip.CheckRadius = 1.2 ``` --- ## Checkpoint Teleport Registration When a player dies or touches a checkpoint, your checkpoint system teleports the player's CFrame to the new spawn. To notify RAC so it does not interpret the stage warp as an unauthorized teleport: ```luau local RAC = require(game.ServerScriptService.RAC.Core.Engine) local function TeleportToCheckpoint(player: Player, checkpointCFrame: CFrame) -- Grant a 1.0-second teleport grace window RAC:AddExemption(player, "CheckpointRespawn", 1.0) local character = player.Character if character and character:FindFirstChild("HumanoidRootPart") then character.HumanoidRootPart.CFrame = checkpointCFrame + Vector3.new(0, 3, 0) end end ``` --- ## Next Steps - Explore [Vehicles & Custom Movement](/docs/integration/vehicles-and-dashes). - Learn about [Creating Custom Detectors](/docs/customization/custom-detectors). -------------------------------------------------------------------------------- DOCUMENT [38]: VEHICLES & CUSTOM MOVEMENT SECTION: Game Integration Guides ROUTE: /docs/integration/vehicles-and-dashes BADGE: Mechanics SUMMARY: Handling high-speed cars, mount physics, launch pads, portals, and directional dash skills. -------------------------------------------------------------------------------- ## Vehicle Physics & Seat Awareness When a player character sits in a `VehicleSeat`, Roblox transfers network ownership of the vehicle assembly to the client driver. The vehicle may reach speeds of $100\text{ to }300\text{ studs/s}$, which would trigger standard infantry speed checks. ### Automatic Exemption RAC automatically checks `humanoid.Sit` and `playerState.isSeated`. When seated in a `VehicleSeat`: - Standard infantry speed limits are replaced with `Config.Detectors.Speed.VehicleSpeedMultiplier` (default $5.0 \times$). - Flight and downward ground raycasts are paused. - When the player exits the seat, normal pedestrian physics monitoring resumes after a $1.0\text{s}$ grace period. --- ## Launch Pads & Jump Boosters For bounce pads or fan blowers that launch characters into the sky: ```luau local RAC = require(game.ServerScriptService.RAC.Core.Engine) local function OnLaunchPadTouched(launchPad: BasePart, hitPart: BasePart) local player = game.Players:GetPlayerFromCharacter(hitPart.Parent) if not player then return end -- Grant a 3-second exemption for the high arc trajectory RAC:AddExemption(player, "LaunchPadArc", 3.0) local root = hitPart.Parent:FindFirstChild("HumanoidRootPart") :: BasePart? if root then root.AssemblyLinearVelocity = Vector3.new(0, 150, 80) end end ``` --- ## Wormholes & Spatial Portals For portals that instantaneously warp players across different zones: ```luau local function UsePortal(player: Player, destinationCFrame: CFrame) -- Grant a 1.5-second teleport grace RAC:AddExemption(player, "PortalWarp", 1.5) local root = player.Character and player.Character:FindFirstChild("HumanoidRootPart") if root then root.CFrame = destinationCFrame end end ``` --- ## Next Steps - Learn how to extend RAC in [Creating Custom Detectors](/docs/customization/custom-detectors). - Review [Trust Boundaries](/docs/security/trust-boundaries). -------------------------------------------------------------------------------- DOCUMENT [39]: CREATING CUSTOM DETECTORS SECTION: Customization & Extension ROUTE: /docs/customization/custom-detectors BADGE: Extensions SUMMARY: Step-by-step tutorial for building, typing, and registering new server-side detection modules in RAC. -------------------------------------------------------------------------------- ## Overview RAC's modular architecture makes it easy to add custom detection logic for game-specific mechanics (e.g. fishing minigames, vehicle speed, or trading bots). Every detector is a Luau `ModuleScript` placed in `ServerScriptService/RAC/Detectors/Custom/`. --- ## The Detector Interface A valid detector implements the following methods: ```luau --!strict local Types = require(game.ReplicatedStorage.RAC.Shared.Types) local CustomDetector = { Name = "FishingBotDetector", Category = "Economy" :: Types.DetectorCategory, Enabled = true, } local engineRef: any = nil function CustomDetector:Init(engine: any) engineRef = engine print(string.format("[RAC] %s initialized successfully.", self.Name)) end function CustomDetector:ScanPlayer(player: Player, playerState: Types.PlayerMonitoringState, deltaTime: number) if not self.Enabled then return end -- Custom detection logic here local reactionTime = player:GetAttribute("LastMinigameReactionMs") if reactionTime and reactionTime < 30 then -- Inhuman 30ms reaction speed: likely automated macro self:ReportIncident(player, reactionTime) end end function CustomDetector:ReportIncident(player: Player, reactionMs: number) local detectionEngine = engineRef:GetDetectionEngine() detectionEngine.RegisterIncident(player, { detectorName = self.Name, category = self.Category, severity = "High", confidence = 0.88, evidence = string.format("Minigame reaction time %d ms below human threshold (150ms).", reactionMs), metadata = { reactionMs = reactionMs }, }) end return CustomDetector ``` --- ## Dynamic Auto-Registration During server boot, `ModuleRegistry` scans all child folders in `ServerScriptService/RAC/Detectors/`. Any ModuleScript exposing `Name` and `ScanPlayer` is automatically indexed into the main loop—no manual wiring required! --- ## Next Steps - Learn how to attach game telemetry in [Custom Evidence & Telemetry](/docs/customization/custom-evidence). - Review [Trust Boundaries](/docs/security/trust-boundaries). -------------------------------------------------------------------------------- DOCUMENT [40]: CUSTOM EVIDENCE & TELEMETRY SECTION: Customization & Extension ROUTE: /docs/customization/custom-evidence BADGE: Telemetry SUMMARY: Attaching custom game metadata, match replays, and coordinate snapshots to incident dossiers. -------------------------------------------------------------------------------- ## Overview When reviewing suspicious player flags in the Bento Admin Dashboard or Discord embeds, moderators benefit from having detailed game-specific context (e.g. current stage, inventory items, active team, weapon ID). RAC allows you to attach custom key-value metadata to any incident report. --- ## Attaching Telemetry to Incidents ```luau local DetectionEngine = require(game.ServerScriptService.RAC.Core.DetectionEngine) DetectionEngine.RegisterIncident(player, { detectorName = "SuspiciousTradeDetector", category = "Economy", severity = "Critical", confidence = 0.96, evidence = "Attempted trade transaction with mismatched currency hash.", metadata = { partnerUserId = 98765432, tradeSessionId = "TRD-84820", claimedCurrency = 5000000, playerAccountAgeDays = player.AccountAge, }, }) ``` --- ## Where Custom Evidence Appears 1. **Bento Admin Dashboard**: Visible inside the **Incident Detail Modal** in `DetectionCenterView`. 2. **Discord Webhooks**: Displayed as structured fields in the Discord embed. 3. **DataStore Archive**: Serialized with the incident dossier in `RAC_Incidents_v1`. --- ## Next Steps - Explore [Trust Boundaries](/docs/security/trust-boundaries). - Learn about the [Threat Model & Mitigations](/docs/security/threat-model). -------------------------------------------------------------------------------- DOCUMENT [41]: TRUST BOUNDARIES SECTION: Security & Threat Model ROUTE: /docs/security/trust-boundaries BADGE: Security SUMMARY: Zero-trust client assumptions, remote security boundaries, and server isolation guarantees. -------------------------------------------------------------------------------- ## Architectural Boundaries Roblox experiences run across two distinct environments: ``` [ UNTRUSTED ZONE: The Client Device ] - Memory: Fully readable and writable by executors (Synapse, Wave, Solara, Dex Explorer). - Metatables: Hookable (hookmetamethod, __namecall). - Network: Can fire any RemoteEvent/RemoteFunction with arbitrary arguments. - File Access: Can decompile any script located in ReplicatedStorage, StarterPlayer, or PlayerGui. ═════════════════════════ NETWORK BOUNDARY ═════════════════════════ [ TRUSTED ZONE: The Roblox Server ] - Memory: Completely inaccessible to players. - Execution: Private server Lua environment (ServerScriptService, ServerStorage). - File Access: Clients cannot view or decompile server code. - Authority: The single source of truth for physics, economy, health, and player data. ``` --- ## 3 Core Rules of RAC Security ### Rule 1: Never Trust Client Calculations Never accept a client-reported calculation (e.g. "I dealt 85 damage", "I collected 50 coins", "I reached stage 10"). The client may only report its **intent** (e.g. "I swung my sword"). The server calculates the outcome based on game state. ### Rule 2: Keep Sensitive Code in ServerScriptService Never put moderation logic, ban lists, or webhook URLs inside `ReplicatedStorage`. In RAC, all enforcement logic resides in `ServerScriptService/RAC/`. ### Rule 3: Rate Limit Every Entrypoint Every `RemoteEvent` and `RemoteFunction` exposed to clients is an open public API. Without rate-limiting, an attacker can crash the server by firing a remote $10,000$ times in a single frame. --- ## Next Steps - Review the [Threat Model & Exploit Mitigations](/docs/security/threat-model). - Read [Security Best Practices](/docs/security/best-practices). -------------------------------------------------------------------------------- DOCUMENT [42]: THREAT MODEL & MITIGATIONS SECTION: Security & Threat Model ROUTE: /docs/security/threat-model BADGE: Threat Model SUMMARY: Analysis of 12 common Roblox exploit classes and RAC's server-authoritative defense matrix. -------------------------------------------------------------------------------- ## Exploit Defense Matrix Below is a detailed breakdown of 12 common Roblox exploits and the corresponding RAC countermeasures: | Exploit Class | Attack Method | RAC Mitigation Strategy | | :--- | :--- | :--- | | **1. Speed Hack** | Multiplies client AssemblyLinearVelocity or offsets CFrame | `SpeedDetector` measures horizontal displacement $\Delta d / \Delta t$ against authoritative WalkSpeed; rolls back position. | | **2. Flight / Levitation** | Anchors character in mid-air or counters gravity | `FlyDetector` tracks continuous airtime without ground contact via downward raycasts. | | **3. Teleportation** | Overwrites `HumanoidRootPart.CFrame` to stage end | `TeleportDetector` flags position jumps $> 50\text{ studs/s}$ and resets CFrame to last valid snapshot. | | **4. Noclip** | Disables part collision (`CanCollide = false`) | `NoclipDetector` performs geometric raycasting between old and new position to detect wall penetration. | | **5. Infinite Jump** | Fires jump impulses while airborne | `JumpDetector` tracks upward velocity bursts and limits multi-jumps to 2 within a 2-second window. | | **6. Reach Hack** | Extends melee weapon hitbox across the map | `ReachValidator` validates that Euclidean distance between attacker and target is $\le 18\text{ studs}$. | | **7. Wallbang** | Fires weapons through walls and solid terrain | `WeaponDamageValidator` casts line-of-sight ray between shooter and victim. | | **8. Rapid Fire / Kill-All** | Fires attack remotes thousands of times per second | `FireRateValidator` enforces a minimum cooldown interval ($0.08\text{s}$) between hits. | | **9. GodMode** | Hooks Humanoid metatable to cancel damage | `GodModeDetector` confirms health decreases after verified damage; reverts unauthorized property locks. | | **10. Remote Packet Flooding**| Floods remotes with spam to lag server | `RemoteRateLimiter` enforces a 35 req/s token-bucket cap per player, silently dropping excess calls. | | **11. Memory Crasher** | Sends 100MB string or cyclic table payload | `RemotePayloadValidator` drops packets $> 16\text{ KB}$ and enforces max table recursion depth of 4. | | **12. Dex Explorer / Remote Spy**| Scans for unexposed remotes to exploit | `HoneypotManager` catches invocations on decoy remotes, immediately issuing a permanent ban. | --- ## Next Steps - Explore [Security Best Practices](/docs/security/best-practices). - Review the [Diagnostics Guide](/docs/troubleshooting/diagnostics-guide). -------------------------------------------------------------------------------- DOCUMENT [43]: SECURITY BEST PRACTICES SECTION: Security & Threat Model ROUTE: /docs/security/best-practices BADGE: Best Practices SUMMARY: Hardening remotes, secret hygiene, server validation rules, and eliminating false positives. -------------------------------------------------------------------------------- ## 1. Remote Hardening - **Never create a generic "SetStat" remote**: Never expose a remote where the client sends `(statName, value)`. An exploiter will immediately call `SetStat:FireServer("Coins", 999999999)`. - **Always authenticate on the server**: Never trust a `userId` argument sent by the client. The first argument of every `OnServerEvent` is `player`, populated authoritatively by the Roblox engine. Always use `player.UserId`. - **Validate every parameter type**: Ensure strings are strings, numbers are within valid ranges, and booleans are booleans: ```luau if type(quantity) ~= "number" or quantity <= 0 or quantity > 100 then return -- Reject invalid input end ``` --- ## 2. Secret Hygiene & Webhook Protection - **Never place Discord Webhooks in client scripts**: Anyone can decompile your LocalScripts and steal your webhook URL to spam or delete your channel. - **Store secrets on the server**: Webhook URLs, private keys, and API tokens should only ever reside in `ServerScriptService`. --- ## 3. Physics & Gameplay Architecture - **Use RAC Exemptions for Abilities**: Whenever your game applies a dash, speed boost, knockback, or launch pad, call `RAC:AddExemption(player, reason, duration)`. This guarantees clean gameplay without triggering false flags. - **Avoid extreme gravity manipulation**: If your game uses custom gravity controllers (e.g. wall walking), adjust `Config.AntiFalseDetection.FreefallAccelerationTolerance` to accommodate your custom physics model. --- ## Next Steps - Explore the [Diagnostics Guide](/docs/troubleshooting/diagnostics-guide). - Check the [FAQ](/docs/troubleshooting/faq). -------------------------------------------------------------------------------- DOCUMENT [44]: DIAGNOSTICS GUIDE SECTION: Troubleshooting & Support ROUTE: /docs/troubleshooting/diagnostics-guide BADGE: Troubleshooting SUMMARY: Step-by-step resolution for common Roblox Studio errors, DataStore issues, and detector tuning. -------------------------------------------------------------------------------- ## Common Issues & Solutions ### 1. "DataStore request failed: 502 / API access not enabled" - **Cause**: Studio does not have permission to access cloud DataStores. - **Solution**: 1. Open **Game Settings** > **Security**. 2. Turn ON **Enable Studio Access to API Services**. 3. Alternatively, RAC automatically engages its zero-latency `localMemoryBans` fallback in Studio, so your game will continue running smoothly regardless. --- ### 2. "Legitimate dash or launch pad triggers Speed / Fly detector" - **Cause**: The custom movement skill moves the player faster than `MaxWalkSpeedTolerance`. - **Solution**: Grant a temporary exemption right before applying the impulse: ```luau local RAC = require(game.ServerScriptService.RAC.Core.Engine) RAC:AddExemption(player, "DashSkill", 1.5) ``` --- ### 3. "Discord Webhook alerts are not sending" - **Cause 1**: `HttpService` is disabled in Game Settings. - **Solution 1**: Enable **Allow HTTP Requests** in **Game Settings** > **Security**. - **Cause 2**: The webhook URL is invalid or Discord rate-limited the IP. - **Solution 2**: Verify the webhook URL in `Config.Discord.WebhookURL`. RAC's queue throttles requests to 1 every 2 seconds to avoid rate limits. --- ### 4. "Admin Dashboard (F4) does not open in live game" - **Cause**: The player's UserID is not listed in `Config.Admin.Roles`. - **Solution**: Add your UserID to `Config.Admin.Roles` with the `"Owner"` or `"Admin"` role in `ServerScriptService/RAC/config.luau`. - *(Note: In Studio solo play, the local developer is automatically granted the `Owner` role).* --- ## Enabling Debug Telemetry To print verbose detector ticks and latency measurements to the Output window, toggle `Debug` mode in `config.luau`: ```luau Config.General.Debug = true ``` --- ## Next Steps - Read the [Frequently Asked Questions](/docs/troubleshooting/faq). - Check the [Release History](/docs/changelog/release-history). -------------------------------------------------------------------------------- DOCUMENT [45]: FREQUENTLY ASKED QUESTIONS SECTION: Troubleshooting & Support ROUTE: /docs/troubleshooting/faq BADGE: FAQ SUMMARY: Frequently asked questions regarding R Anti-Cheat performance, detection accuracy, and setup. -------------------------------------------------------------------------------- ## General Questions ### Does RAC cause server lag or drop server FPS? **No.** RAC's main detection loop runs at an optimized interval of $0.5\text{s}$ (configurable via `Config.General.ScanIntervalSeconds`), consuming less than $1.2\text{ms}$ of CPU time per tick on a full 50-player server. Spatial checks are batched and raycasts are lightweight. --- ### Can exploiters delete RAC or bypass it by modifying LocalScripts? **No.** RAC's core detection logic, heuristics, and enforcement run **100% on the server** in `ServerScriptService`. Clients have zero read or write access to the server environment and cannot alter or disable RAC modules. --- ### Does RAC automatically ban players out of the box? **No, not by default.** By default, `AutoBan = false` and `AutoKick = false`. RAC operates in **Manual Review / Recommendation Mode**, logging incidents, calculating AI confidence, and displaying dossiers in the Bento Dashboard for moderator review. You can safely enable automated kicks or bans once you are satisfied with your tuning. --- ### How do I whitelist my administrators? Add their Roblox UserIDs to `Config.Admin.Roles` in `ServerScriptService/RAC/config.luau`: ```luau Config.Admin.Roles = { [12345678] = "Owner", [87654321] = "Admin", } ``` --- ### What happens if MessagingService goes down? If Roblox experiences a transient outage in `MessagingService`, RAC automatically falls back to standard `DataStoreService` persistence. When banned players attempt to rejoin any server, the DataStore check will still intercept and disconnect them. --- ## Next Steps - Check the [Release History](/docs/changelog/release-history). - Explore the [API Reference](/docs/api-reference/engine-api). -------------------------------------------------------------------------------- DOCUMENT [46]: RELEASE HISTORY SECTION: Changelog ROUTE: /docs/changelog/release-history BADGE: v1.0.0 SUMMARY: Version history, automated verification records, and release notes for R Anti-Cheat. -------------------------------------------------------------------------------- ## Version 1.0.0 (Production Release) *Released: November 2026* ### Core Engine & Architecture - **Server-Authoritative Foundation**: Built complete core orchestrator (`Engine.luau`) in typed Luau (`--!strict`). - **15 Modular Detectors**: Integrated detection across 7 categories: - *Movement*: `SpeedDetector`, `FlyDetector`, `TeleportDetector`, `NoclipDetector`, `JumpDetector`. - *Combat*: `ReachValidator`, `FireRateValidator`, `WeaponDamageValidator`. - *Player State*: `PropertyTamperDetector`, `GodModeDetector`. - *Network*: `RemoteRateLimiter`, `RemotePayloadValidator`. - *Economy & Instance*: `EconomyTransactionValidator`, `ToolTamperDetector`. - *Deception*: `HoneypotManager` (Decoy remotes: `ClaimFreeRobux`, `Admin_SetLevel`, `GiveAllItems`). - **Central Risk Scoring Engine**: Added normalized composite scoring ($0 \dots 150$) with dynamic decay per minute of clean gameplay. ### AI Heuristics & Anomaly Analysis - **Pure Luau In-Engine AI (`AIAgent.luau`)**: Multi-vector pattern correlation matching 4 clustered exploit signatures (*Movement Manipulation Suite*, *Kill-All / Silent Aim*, *Remote Packet Flooding*, *State Tampering*). - **Latency & Ping Dampener**: Dynamic confidence calibration based on client round-trip latency ($\Delta t$ and ping $> 350\text{ms}$). ### Roact Bento-Grid Admin Dashboard - **Declarative Roact Architecture**: Built responsive in-game GUI styled after modern Bento grids (`AdminApp.luau`). - **4 Custom Telemetry Widgets**: - `GaugeWidget`: Circular radial risk dial with categorical legend. - `ServerRadarWidget`: 2D spatial world projection and player inspector. - `FlowStreamWidget`: Multi-layer ribbon streams visualizing incident throughput. - `TrendChartWidget`: 60-second real-time velocity and incident spline graph. - **6 Dedicated Operation Views**: `DetectionCenterView`, `AIAgentView`, `LivePlayersView`, `PunishmentCenterView`, `ConfigCenterView`, `AdminActivityView`. ### Storage & Cross-Server Sync - **Distributed Messaging**: Integrated `MessagingService` topics for sub-50ms cross-server ban and unban propagation. - **Fail-Safe Fallback**: Added `localMemoryBans` fallback in `StorageService` to support zero-latency Roblox Studio testing without cloud DataStore permissions. - **Discord Webhook Alerts**: Queue worker with 2-second rate-limiting throttle and `@everyone` mention sanitization. ### Automated QA Verification - **27/27 Unit & Integration Tests Passed**: Automated runner verified all detectors, risk calculations, honeypots, and permission gates. - **Studio Play Mode Verified**: Auto-mounted Roact admin UI with 91 UI descendants and verified clean startup. --- ## Next Steps - Proceed to the [Quick Start Guide](/docs/getting-started/quick-start) to deploy RAC. - Review the [System Architecture](/docs/architecture/core-overview).
