Phase 28 Session 1: Foundation - BiomeSystem & ChunkManager
WORLD EXPANSION - Foundation systems created: 1. BiomeSystem.js (250 lines) - 5 biome definitions (Grassland, Forest, Desert, Mountain, Swamp) - 500x500 biome map generation - Region-based biome placement - Feature spawn probability per biome - Biome-specific tile coloring - Transition detection - Statistics tracking 2. ChunkManager.js (200 lines) - 50x50 tile chunk system - 3x3 chunk loading (9 active chunks) - Auto-load/unload based on player position - Performance optimization (loads 22,500 tiles vs 250,000) - 91% memory reduction - Chunk caching and statistics 3. Documentation - PHASE28_WORLD_EXPANSION_PLAN.md (complete roadmap) - PHASE28_SESSION1_LOG.md (progress tracking) Integration: - Both systems added to index.html - Ready for GameScene integration Next steps: - Initialize BiomeSystem in GameScene - Initialize ChunkManager in GameScene - Update Flat2DTerrainSystem for biome support - Expand world to 500x500 - Update camera bounds Status: Foundation complete (60% of Session 1) Time: 40 minutes Files: 5 created, 1 modified
