🔧 Game Fixes Applied - November 19, 2025

Issues Fixed

1. ✅ Cannot Answer Card Questions

Problem: Card modal wasn't receiving data properly from backend
Root Cause: Backend sends game:card-drawn-self event with nested structure { cardData: {...}, timeLimit: 60 } but frontend was trying to access fields directly
Solution:

• Updated handleCardDrawn in GameScreen.jsx to properly extract cardData from nested structure
• Added support for hint field
• Properly handles both game:card-drawn and game:card-drawn-self events

Files Modified:

• SerpentRace_Frontend/src/pages/Game/GameScreen.jsx (lines 249-263)

const handleCardDrawn = (data) => {
  // Backend sends cardData nested in game:card-drawn-self event
  const cardData = data.cardData || data;
  setCurrentCard({
    id: cardData.cardId || cardData.id,
    type: cardData.cardType || cardData.type,
    question: cardData.question || cardData.text || cardData.statement,
    answerOptions: cardData.answerOptions || cardData.options || [],
    correctAnswer: cardData.correctAnswer,
    hint: cardData.hint,
    points: cardData.points || 0,
    timeLimit: data.timeLimit || cardData.timeLimit || 60
  })
  setIsCardModalOpen(true)
}

2. ✅ Player Turn Indicator Not Working

Problem: Turn indicator wasn't updating properly
Root Cause: Frontend didn't know which player was the current user to compare with gameState.currentPlayer
Solution:

• Added playerIdentifier state to GameWebSocketContext
• Decode gameToken on connect to extract userId or playerName
• Added isMyTurn computed value that compares gameState.currentPlayer with playerIdentifier

Files Modified:

• SerpentRace_Frontend/src/contexts/GameWebSocketContext.jsx (lines 16, 57-62, 88-97, 488-489)

// In GameWebSocketContext
const [playerIdentifier, setPlayerIdentifier] = useState(null);

// Decode token to get player identifier
try {
  const payload = JSON.parse(atob(gameToken.split('.')[1]));
  const identifier = payload.userId || payload.playerName;
  setPlayerIdentifier(identifier);
  log('🎮 Player identifier:', identifier);
} catch (err) {
  logError('Failed to decode game token:', err);
}

// Check if it's the current player's turn
const isMyTurn = useMemo(() => {
  if (!gameState?.currentPlayer || !playerIdentifier) return false;
  return gameState.currentPlayer === playerIdentifier;
}, [gameState?.currentPlayer, playerIdentifier]);

3. ✅ Current Player Name Not Shown in Indicator

Problem: Turn indicator only showed "Betöltés..." or player ID instead of player name
Root Cause: Inconsistent player ID format (some by userId, some by playerName)
Solution:

• Updated player lookup to check multiple possible ID formats
• Highlights current player name in green when it's your turn
• Shows "← Te vagy!" (It's you!) indicator next to your name

Files Modified:

• SerpentRace_Frontend/src/pages/Game/GameScreen.jsx (lines 470-476)

{currentTurn && (
  <div className="text-gray-400 text-xs mt-1">
    🎯 Köron: <span className={`font-bold ${isMyTurn ? 'text-green-400' : 'text-white'}`}>
      {players.find(p => p.id === currentTurn || p.playerName === currentTurn || p.name === currentTurn)?.name || currentTurn || 'Betöltés...'}
    </span>
    {isMyTurn && <span className="ml-2 text-green-400 animate-pulse">← Te vagy!</span>}
  </div>
)}

4. ✅ Dice Shown Even When Not Player's Turn

Problem: Dice was always interactive regardless of whose turn it was
Root Cause: No turn validation on dice display
Solution:

• Added conditional rendering based on isMyTurn flag
• When it's your turn: Shows green pulsing text "🎯 A te köröd! Kattints a kockára dobáshoz!"
• When it's NOT your turn: Shows gray text "⏳ Várd meg a köröd..." and dice is disabled with 50% opacity and pointer-events-none

Files Modified:

• SerpentRace_Frontend/src/pages/Game/GameScreen.jsx (lines 609-625)

{isMyTurn ? (
  <>
    <p className="text-green-400 text-sm mb-4 font-bold animate-pulse">
      🎯 A te köröd! Kattints a kockára dobáshoz!
    </p>
    <Dice onRoll={handleDiceRoll} />
  </>
) : (
  <>
    <p className="text-gray-500 text-sm mb-4">
      ⏳ Várd meg a köröd...
    </p>
    <div className="opacity-50 pointer-events-none">
      <Dice onRoll={handleDiceRoll} />
    </div>
  </>
)}

Additional Improvements

Debug Panel Enhancement

Added debug information to help verify turn system:

• 🆔 My ID: Shows current player's identifier (userId or playerName)
• ✅ Is My Turn: Shows YES/NO to quickly verify turn detection

Files Modified:

• SerpentRace_Frontend/src/pages/Game/GameScreen.jsx (lines 643-644)

Technical Details

Token Structure

The gameToken is a JWT containing:

{
  "gameId": "uuid",
  "gameCode": "ABC123",
  "playerName": "Player1",
  "isAuthenticated": true/false,
  "userId": "uuid" // only for authenticated players
}

Player Identification Logic

Backend uses: playerIdentifier = socket.userId || socket.playerName
Frontend now extracts: payload.userId || payload.playerName from decoded token

This ensures both authenticated users (with userId) and guest players (with only playerName) work correctly.

Testing Checklist

✅ Card System

• Draw a card and verify modal opens with question
• Verify answer options display correctly (for quiz cards)
• Submit answer and verify it's sent to backend
• Check hint displays if available
• Verify timer countdown works

✅ Turn System

• Game starts and first player sees "🎯 A te köröd!"
• Other players see "⏳ Várd meg a köröd..."
• Turn indicator shows correct player name
• "← Te vagy!" appears next to your name when it's your turn
• Name is highlighted in green when it's your turn

✅ Dice Control

• Dice is interactive (clickable) only on your turn
• Dice is grayed out and disabled when not your turn
• Text changes from green "A te köröd!" to gray "Várd meg a köröd..."

✅ Multi-Player Testing

• Test with 2+ authenticated players
• Test with guest players (no login)
• Test with mix of authenticated and guest players
• Verify turn rotation works correctly
• Each player can only act on their turn
