Anti-Wallhack Visibility System

📊 Performance Benchmarks

Worst-case stress test: a 50m × 50m high-density arena with 2 teams, 32 visibility updates per second, 180° FOV-based observer detection and Environment Detection disabled. System time is the cost of the visibility system itself; FPS impact is the measured framerate drop against the same scene with the system removed.

🎥 Benchmark Demonstration

Real benchmark session demonstrating system scalability under high-density multiplayer conditions.

10 Players 2.10 ms system time · 1.44% FPS impact

25 Players 5.72 ms system time · 4.86% FPS impact

50 Players 19.43 ms system time · 13.44% FPS impact

100 Players 61.46 ms system time · 44.08% FPS impact

Real multiplayer maps typically distribute players over larger areas, reducing simultaneous visibility checks and lowering server workload.

🔌 Supported Networking Solutions

Designed to work with popular Unity multiplayer frameworks through server-authoritative visibility validation.

Photon Fusion

PUN 2

Mirror

Fish-Networking

Netcode for GameObjects

💡 The system is networking-framework agnostic and can be integrated into other server-authoritative multiplayer solutions.

⚡ Advanced Systems (Pro)

Animation Compensation

Adjusts the player collider from the animated pose, so detection stays accurate while the character moves.

Shadow Detection

Detects players through their projected shadows, using multiple light sources with runtime registration.

Reflection Detection

Detects player visibility through reflective surfaces such as mirrors and glass.

Latency Compensation

Scales visibility margins with measured ping, keeping detection consistent under real network conditions.

Observer Prediction

Anticipates camera movement and adds grace prediction for smoother visibility transitions.

270° Observer Mode

Keeps the normal camera FOV and adds a temporary side expansion toward the rotation direction, widening further as the player's ping grows so fast turns stay fair on poor connections.

Cylinder Geometry

PlayerCylinder represents the player more faithfully than a box, improving precision around corners.

Extended Benchmark Tools

Both editions ship a benchmark scene. Pro extends it with a higher-density stress setup and performance analysis tools.
