### **STEP 3: Create Selection UI Hierarchy**

In Scene Hierarchy:

1. **Find or create Canvas**: `AirplaneMinigameCanvas`

2. **Create Selection Panel**:
   ```
   AirplaneSelectionPanel (GameObject + AirplaneSelectionUI component)
   ├── Background (Image - dark overlay)
   ├── TitleText (TextMeshPro: "Choose Your Airplane")
   ├── ButtonsContainer (Horizontal Layout Group)
   │   ├── JetPlaneButton (Button)
   │   │   ├── Icon (Image)
   │   │   ├── NameText (TextMeshPro: "Jet Plane")
   │   │   └── AbilityIcon (Image - small)
   │   ├── BobbingPlaneButton (Button)
   │   │   └── (same structure)
   │   └── DropPlaneButton (Button)
   │       └── (same structure)
   └── ConfirmButton (Button: "Confirm Selection")
   ```

3. **Configure AirplaneSelectionUI component**:
   - Drag buttons to references:
     * Jet Plane Button → `jetPlaneButton`
     * Bobbing Plane Button → `bobbingPlaneButton`
     * Drop Plane Button → `dropPlaneButton`
     * Confirm Button → `confirmButton`
   - Assign airplane types:
     * `JetPlaneType` → `jetPlaneType`
     * `BobbingPlaneType` → `bobbingPlaneType`
     * `DropPlaneType` → `dropPlaneType`
   - Set colors:
     * Selected Color: Yellow
     * Normal Color: White

4. **Set panel inactive by default** (checked in Inspector)

### **STEP 4: Create Ability Button UI**

In Scene Hierarchy under GameplayUI:

```
AbilityButton (GameObject + AirplaneAbilityButton component)
├── Background (Image - circular button background)
├── AbilityIcon (Image - dynamically set)
├── CooldownFill (Image)
│   └── Fill Type: Radial 360
│   └── Clockwise: ✓
│   └── Fill Origin: Top
└── CooldownText (TextMeshPro - optional: "3.2s")
```

**Configure AirplaneAbilityButton component**:
- Button: Assign Button component
- Ability Icon: Assign icon Image
- Cooldown Fill: Assign fill Image
- Cooldown Text: Assign TextMeshPro (optional)
- Colors:
  * Ready Color: White
  * Cooldown Color: Gray
  * Active Color: Yellow

**Position**: Bottom-right corner, accessible for thumb

**Set inactive by default** (checked in Inspector)

### **STEP 5: Configure AirplaneGameManager**

Select AirplaneGameManager GameObject:

1. **Assign new references**:
   - Selection UI: Drag `AirplaneSelectionPanel`
   - Ability Button: Drag `AbilityButton`

2. **Verify existing references still assigned**:
   - Person Queue
   - Camera Manager
   - Launch Controller
   - Target Validator
   - Spawn Manager

### **STEP 6: Update AirplaneSettings Asset**

Find your `AirplaneSettings` ScriptableObject:

1. **New section appears**: "Airplane Types"
2. **Assign default type**: 
   - Default Airplane Type: Assign `JetPlaneType` (or your preferred default)

This is used as fallback if selection UI is missing.

### **STEP 7: Test in Play Mode**

## 🔧 TROUBLESHOOTING

### Issue: "Cannot resolve symbol 'Abilities'"
**Solution**: Unity needs to recompile scripts. Wait for compilation to finish, or reimport scripts folder.

### Issue: Selection UI doesn't show
**Solution**: 
1. Check `AirplaneGameManager.selectionUI` is assigned
2. Verify panel starts inactive
3. Check game flow starts with `StartGame()`

### Issue: Ability button doesn't appear
**Solution**:
1. Check `AirplaneGameManager.abilityButton` is assigned
2. Verify button starts inactive
3. Ensure airplane has ability (check AirplaneTypeData)
4. Check console for errors

### Issue: Hold doesn't work for Jet ability
**Solution**:
1. Verify InputManager instance exists
2. Check button implements ITouchInputConsumer
3. Test with mouse (click and hold) first
4. Check console for registration messages

### Issue: Airplane doesn't spawn at slingshot
**Solution**:
1. Check `_selectedAirplaneType` is set
2. Verify AirplaneTypeData has prefab assigned
3. Check launch controller has launch anchor
4. Look for errors in console

## 📊 ARCHITECTURE SUMMARY

**Design Patterns**:
- ✅ Strategy Pattern (abilities)
- ✅ State Machine (game states)
- ✅ Observer Pattern (events)
- ✅ Singleton (managers)
- ✅ Template Method (abstract Execute)

**SOLID Principles**:
- ✅ Single Responsibility
- ✅ Open/Closed
- ✅ Liskov Substitution
- ✅ Interface Segregation
- ✅ Dependency Inversion

**Input System**:
- ✅ Uses project's InputManager
- ✅ Implements ITouchInputConsumer
- ✅ Override consumer registration
- ✅ No legacy Input API

## 🚀 EXTENSIBILITY

### Adding New Airplane Type:

1. Create new ability class extending `BaseAirplaneAbility`
2. Override `Execute()` method
3. Create ability ScriptableObject
4. Create AirplaneTypeData asset
5. Add button to selection UI
6. Assign references

**No code changes required!**

### Adding New Ability Property:

1. Add field to ability class
2. Configure in Inspector
3. Use in `Execute()` method

**Example**: Add "boost duration" to JetAbility
```csharp
[SerializeField] private float boostDuration = 3f;
```
