Anti-Wallhack Visibility System

Anti-Wallhack Visibility System is a robust, server-authoritative solution for Unity multiplayer games. It validates line-of-sight using physics linecasts and directional sampling, ensuring players only see what they legitimately should — blocking wallhacks and client-side cheats. Ideal for PvP shooters, tactical games, and stealth experiences.

Why use this asset

• Server-side security: All checks run on the host/server, resistant to tampering
• Real-time events: Subscribe to visibility changes for UI, AI, or animations
• Easy integration: Auto-registers with ObserverManager; works with URP, HDRP, and mobile
• Multiplayer ready: Compatible with Photon Fusion, PUN, Mirror, Netcode for GameObjects, and Fish-Networking

Core Features

• Observer-based FOV validation with aspect ratio and pitch control
• Dynamic and fixed line sampling per face
• UnityEvent relay for no-code event handling
• Editor gizmos for debugging cones, normals, and linecasts
• Performance-optimized with layer masks and adjustable resolution

Quick Setup

1. Add ObserverManager to an empty GameObject
2. Attach PlayerObserver to camera/AI (e.g. FOV=60, viewDistance=30)
3. Attach PlayerVisibilityDetector to players (requires child BoxCollider)
4. Optional: Add VisibilityUnityEventRelay for Inspector-based events
5. Subscribe to OnVisibilityChanged for gameplay logic

Demo Scene Included
Test with multiple players, gizmos, and time scale controls. Works in single-player too for AI and stealth.
