Time for action – comparing the IDs

To compare the IDs, we need to make some changes to the FlipCardFaceUp function.

1. Note that we're folding two existing lines of code inside a new conditional statement:

      function FlipCardFaceUp(card:Card)
      {
        card.isFaceUp = true;
         
        if(aCardsFlipped.IndexOf(card) < 0)
        {
          aCardsFlipped.Add(card);
      
          if(aCardsFlipped.Count == 2)
          {
            playerCanClick = false;
               
            yield WaitForSeconds(1);
               
            if(aCardsFlipped[0].id == aCardsFlipped[1].id)
            {
                 // Match!
                 aCardsFlipped[0].isMatched = true;
                 aCardsFlipped[1].isMatched = true;
                              
            } else 
   {
                aCardsFlipped[0].isFaceUp = false;
                aCardsFlipped[1].isFaceUp = false;
            }   
               
            aCardsFlipped = new List.<Card>();
               
            playerCanClick = true;
          }
        }
      }

   Here, we check to see if the two flipped-over cards have the same ...
