AI ASSISTANT INTEGRATION GUIDE:
-----------------------------
To have the AI assistant automatically implement this API handler for your game:

1. Share your game's details with the AI:
   - Game name
   - Base URL (if different from default)
   - Any specific requirements for score tracking
   - Any special game states or events that need API integration

2. The AI will:
   - Replace "GAME_NAME" with your actual game name
   - Update the base URL if needed
   - Add any game-specific score tracking
   - Integrate with your game's existing code
   - Add necessary event listeners
   - Set up proper score submission points

3. The AI will also:
   - Check your game's code structure
   - Identify where to add API calls
   - Ensure proper initialization
   - Add necessary logging
   - Handle any game-specific edge cases

4. After implementation, the AI will:
   - Verify the integration
   - Test the score submission flow
   - Ensure proper error handling
   - Check for any conflicts with existing code

Example prompt for the AI:
"I need to implement the API handler for my game [GAME_NAME]. 
The game uses [FRAMEWORK/ENGINE] and tracks scores in [LOCATION].
Please help me integrate the API handler and ensure proper score submission."

The AI will then:
1. Analyze your game's code
2. Make necessary modifications
3. Add the API handler
4. Ensure everything works together

// API Handler Template for Games
// --------------------------------
// HOW TO USE:
// 1. Copy this file to your new game project
// 2. Replace "GAME_NAME" with your actual game name (e.g., "zombiearrow", "woodtreasurehunt")
// 3. Include this file in your HTML before your main game script
// 4. Call apiHandler.generateToken() at game start
// 5. Call apiHandler.submitScoreIfNeeded(score) at game end

/* 
INTEGRATION GUIDE:

1. In your HTML file, include this script before your main game script:
   <script src="apiHandler.js"></script>
   <script src="your-game-script.js"></script>

2. In your game initialization code, generate a token:
   if(window.apiHandler && typeof window.apiHandler.generateToken === 'function') {
     window.apiHandler.generateToken();
   }

3. In your game end function, submit the score:
   if(window.apiHandler && typeof window.apiHandler.submitScoreIfNeeded === 'function') {
     window.apiHandler.submitScoreIfNeeded(yourGameScore);
   }

4. Make sure your game exposes the score in a playerData object:
   window.playerData = { 
     score: 0,
     // other game data
   };

5. Update the score in both your game and playerData:
   function updateScore(newScore) {
     // Update your game's internal score
     yourGameScore = newScore;
     
     // Update the playerData object for the API handler
     if (window.playerData) {
       window.playerData.score = newScore;
     }
   }
