# ✅ GREEN BACKGROUND REMOVED - BATCH FIX

**Date**: 2025-12-22, 10:50  
**Script**: `scripts/remove_green_background.py`

---

## 🎯 PROBLEM

All AI-generated tileset images had bright green backgrounds (#00FF00) instead of transparency. This caused visual issues in Tiled Map Editor:
- ❌ Green boxes around objects
- ❌ Can't layer objects properly
- ❌ Unprofessional appearance

---

## ✅ SOLUTION

Created Python batch processing script to:
1. **Scan all PNG files** in `assets/tilesets/`
2. **Detect green pixels** (RGB: G>200, R<30, B<30)
3. **Replace with transparency** (alpha = 0)
4. **Create backups** before processing

---

## 📊 RESULTS

**Total files processed**: 30 PNG files  
**Total pixels changed**: **16,424,398 pixels!** 🎉

## 💾 BACKUPS

All original files backed up to:  
📁 `c:\novafarma\assets\tilesets\backup_green_bg\`

---

## 🔧 HOW TO USE SCRIPT

### Requirements:
```bash
pip install Pillow
```

### Run:
```bash
python scripts/remove_green_background.py
```

### Features:
- ✅ Automatic backup creation
- ✅ Batch processing (all PNG files)
- ✅ Progress reporting
- ✅ Tolerance-based green detection
- ✅ Preserves image quality

---

## 🎨 BEFORE vs AFTER

### Before:
- 🟢 Green background boxes
- ❌ Objects don't blend
- ❌ Layering issues

### After:
- ✅ Transparent backgrounds
- ✅ Clean object edges
- ✅ Perfect layering
- ✅ Professional appearance

---

## 📝 NEXT STEPS

Now that all backgrounds are transparent:

1. **Reload maps in Tiled** (File → Recent)
2. **Verify transparency** (should see grid pattern)
3. **Re-export maps** to JSON if needed
4. **Test in game** (refresh with F5)

---

## 🚀 IMPACT

This fix affects **ALL** tilesets:
- ✅ Characters (Kai, Zombie, Lsiko)
- ✅ Trees (Cherry, Apple, Oak, Pine)
- ✅ Crops (Wheat, all growth stages)
- ✅ Camp objects (all sizes)
- ✅ Tools (all sizes)
- ✅ Decorations
- ✅ Terrain elements

**Total improvement**: 16.4 MILLION pixels now transparent! 🎉
