+# 🌫️ Fog of War - ANIMATED WEATHER FOG!
+
+**Date**: December 13, 2025, 00:46
+
+---
+
+## ✅ FINAL CHANGES
+
+### **1. Animated Fog Effect** 🌊
+- **Before**: Static square tiles (ugly!)
+- **After**: Smooth animated circles that move like real fog!
+
+### **2. Wave Animation**
+- Fog moves in wave pattern
+- `Math.sin()` and `Math.cos()` for smooth movement
+- Slow animation (0.0005 speed)
+
+### **3. Very Light Fog**
+- **Unexplored**: 15% opacity (0.15 alpha)
+- **Explored**: 5% opacity (0.05 alpha)
+- **Visible**: No fog (0% opacity)
+
+### **4. Larger Visible Radius**
+- **Radius**: 8 tiles (you see more!)
+
+### **5. Smooth Circles Instead of Squares**
+- Uses `fillCircle()` instead of `fillRect()`
+- Overlapping circles create smooth fog
+- No more ugly square edges!
+
+---
+
+## 🎨 HOW IT LOOKS NOW
+
+### **Unexplored Areas**
+- Smooth animated fog circles
+- Moves in wave pattern
+- Very light (15% opacity)
+- Looks like real weather fog!
+
+### **Explored Areas**
+- Almost invisible (5% opacity)
+- Gentle wave animation
+- You can see everything clearly
+
+### **Visible Areas**
+- No fog at all
+- Crystal clear view
+

+
+## 🎮 CONTROLS
+
+### **Disable Fog Completely**
+Press `F12` in game, then:
+```javascript
+scene.fogOfWar.disable();
+```
+
+### **Make Even Lighter**
+```javascript
+scene.fogOfWar.setFogAlpha(0.05);  // Super light
+```
+
+### **Make Darker (if needed)**
+```javascript
+scene.fogOfWar.setFogAlpha(0.3);  // Darker
+```
+
+### **Adjust Animation Speed**
+Edit line 170 in `FogOfWarSystem.js`:
+```javascript
+const time = this.scene.time.now * 0.001;  // Faster
+const time = this.scene.time.now * 0.0001; // Slower
+```
+
+---
+
+## 📊 TECHNICAL DETAILS
+
+### **Animation Formula**
+```javascript
+// Wave movement
+const waveX = Math.sin(time + x * 0.1) * 5;
+const waveY = Math.cos(time + y * 0.1) * 5;
+
+// Pulsing alpha
+const alpha = baseAlpha + Math.sin(time + x + y) * 0.05;
+```
+
+### **Rendering**
+- Circles instead of rectangles
+- Overlapping for smooth effect
+- Wave pattern for movement
+- Time-based animation
+
+---
+
+## 🎉 RESULT
+
+**No more ugly square fog!**
+
+Now you have:
+- ✅ Smooth animated fog
+- ✅ Moves like real weather
+- ✅ Very light and subtle
+- ✅ No square edges
+- ✅ Beautiful wave animation
+

+
+**Restart the game to see the new animated fog!** 🔄
