## 9. JavaScript SDK

### 9.1 Overview

The JavaScript SDK provides communication between HTML5 games (running in iframe) and the parent window (ASQ platform).

**Location**: `public/js/game-sdk.js`

### 9.2 SDK Classes

#### ASQGameSDK (For Games in iframe)

Used inside HTML5 games to communicate with parent:

```javascript
// Initialize in your game's index.html
const sdk = new ASQGameSDK();

// Update score during gameplay
sdk.updateScore(currentScore);

// End game and submit final score
sdk.endGame(finalScore, {
    clientDuration: Math.floor((Date.now() - startTime) / 1000),
    levelReached: 5,
    // any additional metadata
});

// Check if SDK is ready
if (sdk.isReady()) {
    // Start game logic
}
```

#### GameBridge (For Parent Window)

Used in the play.blade.php to receive game events:

```javascript
const bridge = new GameBridge(iframeElement, sessionData);

// Listen for events
bridge.onScoreUpdate = (score) => {
    document.getElementById('current-score').textContent = score;
};

bridge.onGameEnd = async (data) => {
    const result = await fetch(`/api/v1/sessions/${sessionId}/submit`, {
        method: 'POST',
        body: JSON.stringify({ score: data.score })
    });
    // Show result modal
};
```

### 9.3 Message Types

| Type          | Direction       | Description                    |
| ------------- | --------------- | ------------------------------ |
| GAME_INIT     | Parent → Game   | Initialize game with session   |
| GAME_READY    | Game → Parent   | Game finished loading          |
| SCORE_UPDATE  | Game → Parent   | Score changed during play      |
| GAME_END      | Game → Parent   | Game finished, submit score    |

### 9.4 Security

- Games run in sandboxed iframe: `allow-scripts allow-same-origin allow-pointer-lock`
- Communication via `postMessage` with origin validation
- Session tokens validated server-side

## 12. Usage Examples

### 12.1 Using GameService

```php
use Modules\Game\Services\GameService;

$gameService = app(GameService::class);

// Check if user can play
$result = $gameService->canUserPlay($userId, $game);
if (!$result['can_play']) {
    // Handle: $result['errors']
}

// Get user stats
$stats = $gameService->getUserGameStats($userId, $gameId);
// Returns: today_plays, total_plays, total_points_earned, best_score, average_score
```

### 12.2 Using GameSessionService

```php
use Modules\Game\Services\GameSessionService;

$sessionService = app(GameSessionService::class);

// Start a session
$session = $sessionService->startSession($user, $game);

// Submit score
$result = $sessionService->submitScore($session, $score, [
    'client_duration' => 120,
    'ip_address' => request()->ip(),
]);
```

### 12.3 Using CoinService

```php
use Modules\Game\Services\CoinService;

$coinService = app(CoinService::class);

// Award coins
$result = $coinService->awardCoins(
    $user,
    100,
    'game_reward',
    'Earned from Staking Adventure',
    'game_sessions',
    $sessionId
);

// Convert to points
$result = $coinService->convertToPoints($user, 500, 1.0);
```

## 13. Production Deployment (January 2026)

### 13.1 HTML5 Game Upload & Integration

Successfully tested with real HTML5 game upload:

**Test Game**: Counting Game (6.3MB ZIP file)
- **Technology**: HTML5 Canvas + WebAssembly (.wasm)
- **Files**: 15+ files including images, scripts, audio
- **Status**: ✅ Successfully uploaded, extracted, and playable

### 13.2 Issues Fixed During Deployment

#### 13.2.1 PHP Upload Configuration
**Problem**: Default PHP upload limit (2MB) too small for game ZIPs
```ini
# Before
upload_max_filesize = 2M
post_max_size = 8M

# After (php.ini)
upload_max_filesize = 64M
post_max_size = 128M
```
**Location**: `/opt/homebrew/etc/php/8.4/php.ini`

#### 13.2.2 Drag & Drop Upload
**Problem**: Direct file assignment to input.files (read-only property)
```javascript
// ❌ Wrong
input.files = dataTransfer.files;

// ✅ Correct
const dt = new DataTransfer();
for (let file of files) {
    dt.items.add(file);
}
input.files = dt.files;
```

#### 13.2.3 ZIP Validation - WASM Support
**Problem**: .wasm files rejected by validation
```php
// Added to GameZipService allowedExtensions
'wasm' => 'application/wasm'
```

#### 13.2.4 macOS Metadata Files
**Problem**: __MACOSX and ._* files causing validation errors
```php
// Auto-skip macOS metadata
if (str_starts_with($entry, '__MACOSX/') || 
    str_contains($entry, '/._')) {
    continue; // Skip validation
}
```

#### 13.2.5 File Accessibility
**Problem**: Extracted games not accessible via HTTP
```bash
# Created symlink
ln -s /absolute/path/storage/app/games /absolute/path/public/storage/games
```

#### 13.2.6 Game List Array Keys
**Problem**: Game list using numeric indices (0,1,2) instead of slugs
```php
// ❌ Before
$games->map(function($game) { return [...]; })

// ✅ After  
$games->mapWithKeys(function($game) {
    return [$game->slug => [...]];
})
```

#### 13.2.7 View Object/Array Mismatch
**Problem**: View expected object properties but received arrays
```blade
{{-- ❌ Before --}}
{{ $game->name }}

{{-- ✅ After --}}
{{ $game['name'] }}
```

#### 13.2.8 API Route Endpoints
**Problem**: Frontend calling wrong API routes
```javascript
// ❌ Before
/api/game/6/start
/api/game/session/123/submit

// ✅ After
/api/v1/games/counting-game/start
/api/v1/sessions/123/submit
```

#### 13.2.9 Authentication Middleware
**Problem**: Sanctum not installed but routes using auth:sanctum
```php
// ❌ Before
Route::middleware(['auth:sanctum'])->group(...)

// ✅ After
Route::middleware(['web', 'auth'])->group(...)
```

#### 13.2.10 Header Layout Spacing
**Problem**: Game header overlapping navbar
```css
.game-play-container {
    margin-top: 80px; /* Added spacing */
}
```

#### 13.2.11 Modal JavaScript Event Binding
**Problem**: Modal play button not working after navigation (bfcache)
```javascript
// Added pageshow event listener
window.addEventListener('pageshow', function(event) {
    if (event.persisted) {
        initGameModal(); // Re-initialize
    }
});
```

#### 13.2.12 Session Management
**Problem**: "Ongoing session" error blocking new plays
```php
// Auto-abandon all playing sessions on play page load
GameSession::forUser($user->id)
    ->forGame($game->id)
    ->playing()
    ->update([
        'status' => 'abandoned',
        'ended_at' => now(),
    ]);

// Create session automatically in controller
$session = $this->sessionService->getActiveSession($user->id, $game->id);
if (!$session) {
    $session = $this->sessionService->startSession($user, $game);
}
```

#### 13.2.13 Type Hints in Service Methods
**Problem**: startSession() expects User object but received integer
```php
// ❌ Before
$this->sessionService->startSession($user->id, $game->id);

// ✅ After
$this->sessionService->startSession($user, $game);
```

### 13.4 Verified Workflow

1. **Admin uploads game ZIP** → ✅ Success (6.3MB Counting Game)
2. **Files extracted to storage** → ✅ /storage/app/games/counting-game/
3. **User views game list** → ✅ /games shows all active games
4. **User clicks "Main sekarang"** → ✅ Modal opens with game preview
5. **User clicks "Main" button** → ✅ Redirects to /games/{slug}/play
6. **Session auto-created** → ✅ GameSession with status "playing"
7. **Game loads in iframe** → ✅ HTML5 game renders correctly
8. **User plays game** → ✅ Game interactive and functional

**Next Testing Steps**:
- Complete game round and submit score
- Verify coins awarded correctly

## 14. Troubleshooting

### Common Issues

| Issue                          | Solution                                    |
| ------------------------------ | ------------------------------------------- |
| ZIP upload fails               | Check PHP upload limits (64M/128M)          |
| Game not loading               | Verify symlink: public/storage/games        |
| Drag & drop not working        | Use DataTransfer API, not direct assignment |
| Score rejected                 | Check anti-cheat logs for flags             |
| Daily limit not resetting      | Verify timezone configuration               |
| Coins not awarded              | Check database transaction logs             |
| Modal button redirects wrong   | Check browser cache, hard refresh (Cmd+R)   |
| "Ongoing session" error        | Sessions auto-abandoned on page load        |
| 302 redirect to /games         | Check canUserPlay validation errors         |

### Debug Commands

```bash
# Check PHP configuration
php --ini
php -i | grep upload_max_filesize

# Clear all playing sessions
php artisan tinker --execute="Modules\Game\Models\GameSession::where('status', 'playing')->update(['status' => 'abandoned', 'ended_at' => now()]);"

# Verify symlink
ls -la public/storage/games

# Check game files
ls -la storage/app/games/counting-game/

# Test file accessibility
curl http://127.0.0.1:8000/storage/games/counting-game/index.html
```

### Log Files

- Application logs: `storage/logs/laravel.log`
- Anti-cheat logs: `storage/logs/anti-cheat.log`
- PHP errors: Check php-fpm or server error logs

---

## 15. Security Considerations

1. **ZIP Slip Prevention**: Path traversal attacks blocked
2. **File Type Validation**: Whitelist approach for allowed extensions (includes .wasm)
3. **macOS Metadata Handling**: Auto-skip __MACOSX and ._* files
4. **Rate Limiting**: Daily limits and cooldowns per user
5. **Anti-Cheat**: Multi-layer validation before awarding coins
6. **Atomic Transactions**: Database locks prevent race conditions
7. **Session Ownership**: Users can only access their own sessions
8. **Auto Session Cleanup**: Old playing sessions auto-abandoned (prevents blocking)
