The user wants me to build a first-person raycasting maze shooter game similar to Wolfenstein 3D. This is a complex project that needs to include:

1. Raycasting engine for 3D rendering on a 2D canvas
2. Textured walls with procedural textures
3. A maze layout
4. Player movement with WASD
5. Turning with arrow keys or mouse
6. Enemies that can be shot
7. Shooting mechanics

Let me create a comprehensive single-file HTML with all the CSS and JS inline. I'll need to implement:

1. **Raycasting Engine**: Cast rays from player position through each column of the screen to determine wall distances and draw textured vertical strips.

2. **Procedural Textures**: Generate textures using canvas or algorithm (brick patterns, stone, etc.)

3. **Maze Generation**: Create a grid-based maze with walls

4. **Player Controls**: 
   - WASD for movement
   - Arrow keys or mouse for turning
   - Click to shoot

5. **Enemies**: Place enemies in the maze that can be shot

6. **Game Loop**: Handle input, update game state, render

Let me build this comprehensive game.

I'll build a complete Wolfenstein 3D-style raycasting maze shooter with procedural textures, enemies, and shooting mechanics.

I've created a complete Wolfenstein 3D-style raycasting maze shooter. Let me verify the file was created correctly.

I've built a complete first-person raycasting maze shooter! Here's what's included: ## Features ### Raycasting Engine - Classic DDA algorithm for wall rendering - Textured walls with distance-based shading - Floor and ceiling with gradients - Fisheye correction for proper perspective ### Procedural Textures (5 types) - **Brick** - Red brick wall pattern with mortar lines - **Stone** - Gray stone blocks with dark outlines - **Wood** - Brown wood planks with grain - **Metal** - Industrial metal door with rivets - **Door** - Brown wooden door with panels ### Maze Generation - Recursive backtracking algorithm for random mazes - 16x16 grid with corridors and walls - Variety of wall textures throughout - Some doors scattered in the maze ### Player Controls - **WASD** - Move forward/backward/strafe - **Arrow Keys** or **Mouse** - Turn left/right - **Click** - Shoot - **R** - Reload ammo ### Combat System - 3 enemy types with different stats: - **Guard** (green) - 30 HP, 10 damage, 100 points - **Soldier** (red) - 50 HP, 15 damage, 200 points - **Officer** (purple) - 80 HP, 25 damage, 300 points - Enemies chase and attack the player - Hit detection via raycasting - Health bars above enemies - Hit flash feedback ### Visual Effects - Head bobbing while walking - Weapon recoil animation - Muzzle flash when shooting - Damage flash when hit - Distance shading for depth ### UI Elements - HUD showing health, ammo, and score - Minimap in corner showing maze layout - Crosshair centered on screen - Victory/Game Over messages - Instructions overlay Press **Space** to restart after winning or losing!
