• ✅ First-person controls with mouse look and WASD movement
• ✅ WebGL rendering with optimized mesh generation
• ✅ Physics including gravity, jumping, and ground collision
• ✅ Multiple block types (grass, stone, dirt)
• ✅ Sky and fog effects
• ✅ HUD display with position, chunk info, and crosshair

        ├── Play.jsx                      # Updated play page
        └── play.css                      # Updated styles

🚀 Quick Setup

1. Create the Directory Structure

mkdir -p src/elge/minecraft/world
mkdir -p src/elge/minecraft/renderer
mkdir -p src/elge/minecraft/player

2. Copy the Game Files

# Copy game engine files
cp WorldGenerator.js src/elge/minecraft/world/
cp ChunkMesh.js src/elge/minecraft/world/
cp MinecraftRenderer.js src/elge/minecraft/renderer/
cp PlayerController.js src/elge/minecraft/player/
cp MinecraftGame.js src/elge/minecraft/

# Copy React components
cp Play-minecraft.jsx src/pages/Play.jsx
cp play-minecraft.css src/pages/play.css

3. Deploy and Play!

npm run dev
# Navigate to http://localhost:5173/play

🎮 How to Play

Controls

• W/A/S/D - Move forward/left/backward/right
• Space - Jump
• Mouse - Look around
• ESC - Release mouse cursor
• Click canvas - Capture mouse for controls

Tips

• The game spawns you at Y=70 (above ground)
• Terrain generates procedurally as you explore
• Chunks load/unload automatically based on your position
• Green blocks = grass, gray = stone, brown = dirt

🔧 Technical Details

Architecture

MinecraftGame (main coordinator)
├── WorldGenerator (terrain heightmap & blocks)
├── ChunkMesh (geometry building)
├── MinecraftRenderer (WebGL rendering)
└── PlayerController (input & physics)

Performance

• Chunk size: 16x128x16 blocks
• Render distance: 3 chunks (48 blocks)
• Mesh optimization: Only visible faces rendered
• Target FPS: 60
• Low-end friendly: Optimized for integrated graphics

World Generation

Uses multi-octave noise for realistic terrain:

• Base height: 64 blocks
• Variation: ±30 blocks
• Octaves: 4 (for detail)
• Scale: 0.05 (controls feature size)

🎨 Customization

Change Render Distance

Edit MinecraftGame.js:

generateChunksAroundPlayer() {
  const renderDistance = 5; // Increase for more chunks (may impact FPS)
  // ...
}

Add New Block Types

Edit ChunkMesh.js:

static BLOCK_COLORS = {
  0: [0, 0, 0, 0],           // Air
  1: [0.5, 0.5, 0.5, 1],     // Stone
  2: [0.2, 0.8, 0.2, 1],     // Grass
  3: [0.6, 0.4, 0.2, 1],     // Dirt
  4: [0.7, 0.5, 0.3, 1],     // Wood (add this)
  5: [0.2, 0.6, 0.2, 1],     // Leaves (add this)
};

Then update WorldGenerator.js to place the new blocks.

Adjust Movement Speed

Edit PlayerController.js:

constructor() {
  this.moveSpeed = 0.2;      // Increase for faster movement
  this.lookSpeed = 0.003;    // Increase for faster camera
  this.jumpForce = 0.6;      // Increase for higher jumps
}

Change Sky Color

Edit MinecraftRenderer.js:

render() {
  this.gl.clearColor(0.6, 0.8, 1.0, 1.0); // Change RGB values
  // ...
}

🐛 Troubleshooting

Black screen or no rendering

• Check browser console for WebGL errors
• Ensure your GPU supports WebGL
• Try refreshing the page
• Check that all files are in correct directories

Low FPS / Lag

• Reduce render distance in MinecraftGame.js
• Close other browser tabs
• Lower browser window size
• Check GPU usage in task manager

Mouse not capturing

• Make sure you clicked the canvas
• Check that pointer lock is supported (Chrome/Firefox/Edge)
• Try clicking the canvas again

Import errors

# Make sure file paths match your structure
# Check that all imports use correct relative paths

• Follows ELGE's architecture patterns
• Can be extended with ELGE's advancement system

📝 Code Quality

• No external dependencies (pure JavaScript + WebGL)
• Modular architecture (easy to extend)
• Well-commented code (easy to understand)
• Performance optimized (minimal draw calls)

🎉 You're Done!

Your Minecraft: Web Edition should now be running.

Enjoy building and exploring your procedurally generated world! 🌍
