pubconstBlockType=enum(u8) {
// ... block definitionspubfnisSolid(self: BlockType) bool;
pubfnisTransparent(self: BlockType) bool;
pubfnisOpaque(self: BlockType) bool;
pubfngetColor(self: BlockType) [3]f32;
pubfngetLightEmission(self: BlockType) u4;
pubfngetFaceColor(self: BlockType, face: Face) [3]f32;
};

Adding New Blocks

To add a new block type:

1. Add entry to BlockType enum in src/world/block.zig
2. Register properties in isSolid(), isTransparent(), getLightEmission(), getColor()
3. Add textures to src/engine/graphics/texture_atlas.zig
4. Update src/world/chunk_mesh.zig for special rendering logic

See Contributing for detailed instructions.
