Anti-Wallhack Visibility System (Free)

Anti-Wallhack Visibility System

Anti-Wallhack Visibility System is a robust server-authoritative visibility solution for Unity multiplayer games. It validates line-of-sight using physics-based checks and visibility sampling, ensuring players only receive information they are legitimately allowed to see. Ideal for PvP shooters, tactical multiplayer games, stealth mechanics, and competitive environments.

Why Use This Asset

• Server-authoritative security: Visibility validation runs on the host/server and is resistant to client-side tampering.

• Visibility filtering: Keep teammates, friendly NPCs, or custom entities synchronized regardless of visibility state.

• Real-time events: Subscribe to visibility changes for UI, gameplay systems, and networking logic.

• Easy integration: Includes reference adapter components for popular multiplayer frameworks.

• Multiplayer ready: Compatible with Photon Fusion, PUN 2, Mirror, Netcode for GameObjects, and Fish-Networking.

Core Features (Free Version)

• Observer-based FOV and distance validation

• 180° and 360° observer modes

• Visibility sampling using fixed and dynamic linecasts

• Physics-based line-of-sight validation

• Velocity Compensation for smoother corner-peeking behavior

• Visibility Filtering for teammates and custom gameplay rules
