## ⚠️ Important Flags & Preventing Issues

### Double-Submission Prevention
```typescript
// In PageLevel.onSubmitAnswer()
if (this._isTransitioning) return;  // Blocks rapid re-submission
```

### Double-Click Unlock Prevention
```typescript
// In PageLevel.onUnlockClue()
if (this._isUnlocking) return;  // Blocks rapid hint unlocking
```

### Share Mode Detection
```typescript
// In PageLevel.onViewLoad()
this._isShareMode = params?.shareMode === true;
```

### Timer Running Flag
```typescript
// In PageLevel.onCountdownTick()
if (this._isTimeUp) return;  // Prevents countdown after timeout
```

---

## 🔄 Page Lifecycle Details

### First-Time Open
1. ViewManager.open() called
2. Prefab instantiated
3. onViewLoad() called (do heavy init here)
4. Page added to stack
5. onViewShow() called

### Re-open (if cached)
1. ViewManager.open() called
2. Cache hit found
3. Previous page onViewHide() called
4. This page onViewShow() called (not onViewLoad!)
5. Page already in stack (or re-added)

### Close/Back
1. ViewManager.back() called
2. Current page onViewHide() called
3. Current page destroyed (if not cached)
4. Previous page onViewShow() called

### Destroy
1. onViewDestroy() called
2. All listeners removed
3. Resources cleaned up
4. Node destroyed

---

## 📝 Common Code Patterns

### Open Page with Parameters
```typescript
ViewManager.instance.open('PageLevel', {
  params: { shareMode: true },
  onComplete: (view) => {
    console.log('PageLevel opened');
  },
  onError: (err) => {
    console.error('Failed to open:', err);
  }
});
```

### Get Page Parameters
```typescript
onViewLoad(): void {
  const params = this.getParams();
  if (params?.shareMode) {
    // Handle share mode
  }
}
```

### Show Toast Notification
```typescript
ToastManager.show('提示信息', 2000);  // 2 second display
```

### Check & Consume Points
```typescript
if (StorageManager.hasPoints()) {
  const success = await UserAssetsManager.consumePoint(levelId, hintIndex);
  if (success) {
    this.updatePointsLabel();
  }
}
```

### Schedule & Unschedule
```typescript
startCountdown(): void {
  this.schedule(this.onCountdownTick, 1);  // Every 1 second
}

stopCountdown(): void {
  this.unschedule(this.onCountdownTick);  // Stop callback
}
```

## 🐛 Known Patterns to Watch

### Caching Implications
- Pages with cache:true keep their onViewLoad() state
- onViewShow() is called each time, even if cached
- If you modify state in onViewLoad(), it persists!
- Solution: Reset state in onViewShow() if needed

### Share Mode Edge Cases
- Share mode doesn't save local progress
- Share mode uses ShareManager instead of LevelDataManager
- Share mode clears state on return to home
- Must check _isShareMode before saving

### Modal Positioning
- PassModal instantiated with z-index 999 (topmost)
- Added to Canvas root node (not PageLevel child)
- This allows full-screen coverage with proper Widget alignment

### Timer Edge Cases
- Timer continues even if page is hidden
- Must stop timer on destroy or completion
- onTimeUp() plays sound but doesn't end game automatically
- Wrong answer doesn't stop timer

## 🎯 Tips for Modifications

### Adding New Hint Types
1. Add hint4 config to RuntimeLevelConfig
2. Add unLockItem4 property to PageLevel
3. Add tipsItem4 property to PageLevel
4. Call showUnlockButton(4) in _applyLevelConfig()
5. Handle in onUnlockClue() switch/case

### Adding Page Analytics
1. Add tracking in onViewLoad() (first visit)
2. Add tracking in onViewShow() (each visit)
3. Use page viewId for identification
4. Track user actions in event handlers

### Changing Point System
1. Modify UserAssetsManager (not shown)
2. Update updatePointsLabel() display format
3. Adjust hasPoints() check if needed
4. Test unlock flow with new values

### Adjusting Timer
1. Change `_countdown = 60` to desired seconds
2. Update display frequency if needed
3. Adjust point calculation if time-based
4. Test timeout behavior

## 📞 Quick Troubleshooting

**Page not showing?**
- Check ViewManager.open() called
- Verify prefab has BaseView component
- Check registration in main.ts

**Points not updating?**
- Verify UserAssetsManager call succeeds
- Check updatePointsLabel() is called
- Test StorageManager.getPoints() returns value

**Timer not stopping?**
- Check stopCountdown() called on completion
- Verify unschedule() works in Cocos
- Test onDestroy calls stopCountdown()

**Modal not appearing?**
- Check z-index set to 999
- Verify added to Canvas root
- Test instantiate() succeeds
- Check onViewLoad/Show called manually

**Share mode broken?**
- Verify share code detected in PageLoading
- Check _isShareMode set properly
- Test ShareManager.joinShare() succeeds
- Verify clearShareMode() called on exit
