Time for action – modifying the img argument

Because we're passing a new argument to the Card class, we have to modify the Card class to accept it.

1. Change the Card class code from this:

     class Card extends System.Object
     {
       // (variables omitted for clarity)
       function Card()
       {
         img = "robot";
       }
     }

   to this:

     class Card extends System.Object
     {
        // (variables omitted for clarity)   
        function Card(img:String)
        {
           this.img = img;
        }
     }

2. Now, find the nested loop in the Start function where we added all our new cards to the aGrid array. Change it from this:

      for(j=0; j<cols; j++)
      {
         aGrid[i,j] = new Card();
      }

   to this:

      for(j=0; j<cols; j++)
      {
        var someNum:int = Random.Range(0,aCards.Count);
        aGrid[i,j] = aCards[someNum];
        aCards.RemoveAt(someNum);
      }

What just happened?

This code should look familiar to you, because we're pulling a very similar trick as before. We have a deck of cards—the aCards List. After the BuildDeck...
