Description

A 3D first-person shooter recreated as a single HTML file using DeepSeek-V3.1 and Claude Code. The demo features classic FPS mechanics including WASD movement, mouse look, shooting, and collision detection within a procedurally textured environment.

Descriptions, tags, and model credits may be AI-generated or inferred from public sources and can be incomplete or wrong. Learn more.

Details

Why this is interesting: Impressive demonstration of high-level AI agents building a working, bug-free 3D game with complex mechanics.

Prompts

Prompt 1

- Collision detection with reduced player radius
- Debug display with position/rotation info

6. Code Structure:
- Single HTML file with embedded styles
- Clear separation of initialization, controls, and game loop
- Modular functions for texture generation and collision detection
- Proper event handling for window resize

Include style elements for:
- Centered debug info with monospace font
- debug stats on the left, all details about pos and camera and stuff
- Semi-transparent background for UI elements
- Proper camera rotation limits (-π/2 to π/2 vertical)
- Smooth movement with delta time calculation

The game should start immediately when loaded and require clicking to activate controls.
