Time for action – checking for victory

Our matchesMade, matchesNeededToWin, and playerHasWon variables have been standing at the ready this whole time. Let's finally make use of them.

1. Add these few lines to the FlipCardFaceUp function, where you're detecting a match:

   if(aCardsFlipped[0].id == aCardsFlipped[1].id)
    {
      // Match!
      aCardsFlipped[0].isMatched = true;
      aCardsFlipped[1].isMatched = true;
               
      matchesMade ++;
               
      if(matchesMade >= matchesNeededToWin)
      {
        playerHasWon = true;
      }
   

2. Add a new function call to the OnGUI function:

     function OnGUI () {
        GUILayout.BeginArea (Rect (0,0,Screen.width,Screen.height)); 
        BuildGrid();
        if(playerHasWon) BuildWinPrompt();
        GUILayout.EndArea();
      }

3. And, now, we'll use some GUILayout commands that we learned in the last chapter to display a "win" prompt to the player. Write this new function apart from the other functions, and make sure it's not wedged inside any other function's curlies:

    function...
