From 1713e7a955aeaffb379e9864c7aafe6391472700 Mon Sep 17 00:00:00 2001 From: NovaFarma Dev Date: Mon, 15 Dec 2025 17:01:13 +0100 Subject: [PATCH] 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 --- docs/PHASE28_SESSION1_LOG.md | 84 +++++++ docs/PHASE28_WORLD_EXPANSION_PLAN.md | 329 +++++++++++++++++++++++++++ index.html | 2 + src/systems/BiomeSystem.js | 285 +++++++++++++++++++++++ src/systems/ChunkManager.js | 215 +++++++++++++++++ 5 files changed, 915 insertions(+) create mode 100644 docs/PHASE28_SESSION1_LOG.md create mode 100644 docs/PHASE28_WORLD_EXPANSION_PLAN.md create mode 100644 src/systems/BiomeSystem.js create mode 100644 src/systems/ChunkManager.js diff --git a/docs/PHASE28_SESSION1_LOG.md b/docs/PHASE28_SESSION1_LOG.md new file mode 100644 index 0000000..2161ddb --- /dev/null +++ b/docs/PHASE28_SESSION1_LOG.md @@ -0,0 +1,84 @@ +# 🌍 PHASE 28 - SESSION 1 LOG + +**Date:** 15.12.2025 16:57 +**Session:** Foundation +**Status:** IN PROGRESS ⚑ + +--- + +## βœ… **COMPLETED:** + +### **1.
