Time for action - modify the img argument

Because we're passing a new argument to the Card class, we have to modify Card 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(var j:int=0; j<cols; j++)
   {
   aGrid[i][j] = new Card();
   }
   

   to this:

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