# 🧪 PHASE 28 - SESSION 3: BIOME VISUAL TESTING

**Date:** 15.12.2025 17:18  
**Session:** Visual Verification & Debugging  
**Status:** 🔄 IN PROGRESS

---

## 🎯 **SESSION 3 OBJECTIVES:**

1. **Verify Console Output** - Check if biomes are loading
2. **Visual Verification** - See if biome colors are different
3. **Chunk Boundaries** - Check for visual seams
4. **Performance** - Verify 60 FPS
5. **Debug** - Fix any rendering issues

---

## 🔍 **EXPECTED CONSOLE OUTPUT:**

```
🌍 Initializing Biome System (500x500 world)...
🌍 Generating biome map...
✅ Biome map generated!
💾 Initializing Chunk Manager...
💾 ChunkManager initialized (chunk size: 50x50)
✅ BiomeSystem & ChunkManager connected to terrainSystem
🎨 Flat2DTerrainSystem initialized (500x500 world)
🗺️ Generating flat 2D map...
🌍 Using BiomeSystem for chunk-based terrain generation
🎨 Creating biome-aware background...
✅ Biome background created, ready for chunks
👤 Spawning player at world center: (250, 250)
💾 Loading initial chunks around player...
📦 Loading chunk (4, 4)
📦 Loading chunk (4, 5)
📦 Loading chunk (4, 6)
📦 Loading chunk (5, 4)
📦 Loading chunk (5, 5)  ← Player chunk (center)
📦 Loading chunk (5, 6)
📦 Loading chunk (6, 4)
📦 Loading chunk (6, 5)
📦 Loading chunk (6, 6)
✅ Chunk (5, 5) rendered with biomes
✅ Loaded 9 chunks (22500 tiles)
```

## 🐛 **POTENTIAL ISSUE:**

**Problem:** Chunk tiles might be rendering UNDER the background!

**Reason:** Background depth = 0, chunk tiles depth = 1

**Solution:** Check if tiles are actually visible or covered

## ✅ **TESTING CHECKLIST:**

- [ ] Game loads without errors
- [ ] Console shows biome initialization
- [ ] Console shows chunk loading (9 chunks)
- [ ] Player spawns at (250, 250)
- [ ] Can see biome-colored tiles
- [ ] Different colors in different areas
- [ ] No visual gaps between chunks
- [ ] 60 FPS maintained
- [ ] Player can move to trigger chunk loading
- [ ] New chunks load as player moves

---

## 📊 **DEBUG COMMANDS:**

Open console (F12) and try:

```javascript
// Check if biomeSystem exists
console.log(this.scene.scenes[1].biomeSystem);

// Check if chunkManager exists
console.log(this.scene.scenes[1].chunkManager);

// Get chunk stats
console.log(this.scene.scenes[1].chunkManager.getStats());

// Get biome stats
console.log(this.scene.scenes[1].biomeSystem.getBiomeStats());

// Check current player position
const pos = this.scene.scenes[1].player.getPosition();
console.log(`Player at (${pos.x}, ${pos.y})`);

// Get biome at player position
const biome = this.scene.scenes[1].biomeSystem.getBiomeAt(pos.x, pos.y);
console.log(`Player is in: ${biome} biome`);
```
