Roblox MSSE Anti-Cheat v2.1

Nothing ruins a Roblox game faster than exploiters flying through your walls, spamming your remote events to crash your servers, and stealing your entire economy . Most free anti-cheats found in the toolbox are broken, cause lag, or rubber-band innocent players who just have a high ping.
This is a premium, enterprise-grade server security framework built from the ground up under strict Luau type-safety guidelines using the strict annotation flag. It runs on highly optimized math models and spatial queries, giving your game great protection while keeping server CPU overhead and memory footprint the same if not lower.

Features Included:

1. Sliding Pointer Remote Rate Limiter

• Optimizations: Standard rate limiters create new tables or force slow array shifts every time a player triggers a remote. If a hacker spams an event, the server crashes from garbage collection lag. This engine tracks timing structures safely by managing index memory directly, freeing old slots without shifting array structures.
• O(1) Evaluation Speed: It uses a single math-driven calculation step subtracting the head index from the total array length to calculate the active requests count instantly. The server can easily handle millions of malicious exploit requests without dropping frames of performance.
• Anti-Rejoin: Tracks bad actors by permanent Player UserId integers instead of easily changeable names, keeping temporary server bans active even if the exploiter attempts a fast disconnect-and-rejoin loop.

2. Latency-Compensated Speed and Fly Inertia Killer

• No More Innocent Rubber-Banding: It usesthe engine's built-in network delay verification by checking player GetNetworkPing data to dynamically adjust physical movement thresholds for high-latency clients. If a regular player experiences a sudden lag spike, the system adjusts and completely eliminates false-positive flags.
• Total Momentum Eraser: When an exploit threshold is breached, the script forcefully resets AssemblyLinearVelocity to Vector3 zero right before snapping them backward. This stops the hacker's physics inertia so they cannot slide forward past your boundary line. It then forces a secure coordinate rewrite multiplying the previous tracking position by the preserved rotation vector matrix to override the client's physics entirely while keeping their exact view orientation intact.
• Anti-Idling Loophole Patch: Evaluates actual physical displacement distance before executing stationary rest states, stopping hackers from bypassing checks using a teleport-and-stop trick. It automatically checks the humanoid sitting state boolean to bypass calculations safely while players ride vehicles, stopping big waves of false flags.

3. Spatial Query Anti-Noclip Service

• Wall-Phase Protection: Replaces buggy, heavy physical proxy parts that exploiters can easily find and delete from their machines. Instead, it utilizes memory-isolated box volume parameters using the workspace GetPartBoundsInBox execution line to audit solid geometry intersections purely inside backend server memory arrays.
• Animation-Clip Leeway Cushion: Calculates the precise penetration depth distance past entry wall geometry. It leaves enough visual margin for players whose shoulders naturally clip into a doorway during a running animation, but detects if they try to pass all the way through to the other side.
• Zero Jitter Session Guards: Built with unique, incrementing thread lifecycle tracking tokens by adding one to the current session ID count to explicitly invalidate and terminate old background threads when a character respawns or resets. This protects your server from overlapping loop threads that cause permanent memory leaks.

Setup and Deployment Protocol
Every asset module is engineered for easy installation. Just follow the README instructions and these ones:

1. Drop the master script file directly into ServerScriptService as a standard server Script.
2. Create a folder named exactly OwnershipParts directly within your main Workspace directory for tracking physics items.
3. Ensure Enable Studio Access to API Services is toggled on inside your game settings tab so the database can connect.

Detection Framework Summary

• Thread-Isolated Table Allocation: Utilizes private OverlapParams structures mapped per player session to completely eliminate multi-user calculation data races.
• Sliding Window Index Pointer: Utilizes a constant-time tracking layout that updates a head index number to evaluate package frequencies without loop overhead.
• UserId Boundary Key Isolation: Utilizes isolated string formatting keys containing the user ban phrase combined with the player account number inside the registry to completely bypass the restrictive 4MB Roblox single-key DataStore limit.
• Incremental Displace Time Delta Checks: Utilizes strict timestamp calculation windows across an isolated loop thread to compute active speed and movement velocities.
• Platform Outage Hardening: Features a built-in verification gate that catches unreachable database connection failures immediately using a secondary fetch success boolean check, safely locking out unverified traffic until global Roblox services recover.
• Inertia Linear Velocity Eradication: Utilizes absolute server-authoritative resets to slam character physics velocity directly to zero the millisecond an exploit threshold breaks.
• Horizontal Flat Vector Filters: Flattens checking metrics to the X and Z axes using a flat vector coordinate conversion line, completely ignoring vertical movement updates to eliminate false flags during skydiving or falling physics.
• Normalized Spatial Overlap Queries: Utilizes native engine bounds in box collision geometry checks rather than inaccurate point-to-point raycasting lines.
