Show images on buttons from an example

Following a Robot Repair example from "Unity 3.x Game Development by Example" book. I have reached a point where I should see whole randomized and pictured layout. (Page 169)

Worked hard and finally solved my issue myself :). For anyone else who might follow the book and run into similar issue this is what I suggest:

1)

Assets/Scripts/sc_GameScript.js(x,x): BCE0048: Type 'Object' does not support slicing.

Under #pragma strict card:Object casting gives you error. So make card:Card to get values from arrays correctly. I dunno why book suggest to do that. Maybe they don't use #pragma strict.

(Perhaps somebody else with more experience can give the reason?)

2)

I completely rewrote the whole card dealing and bulding blocks and saw where was my error. It all stood begind one "/" symbol xD. How typical! Inside Resources.Load I wrtoe "Images/Robots" instead of "Images/Robots*/*"

The important thing here was also that I didn't have the original resources of that example, so I did everything myself and realized I didn't have Resources folder created inside the project tab. When using Resources.Function_name you need to have Resources folder created! I missed that.

Instead of loading image inside Button function, I completely moved it into Card class's constructor function. That way resource isn't loaded on every frame, but instead on Card instance creation!

Relevant parts of the code:

     class Card extends System.Object //Create the class
     {
      var img:Texture; //Create a texture variable
     
      function Card(imgName:String) //The constructor is the very first function that gets called, automatically
      {
                  //This is where I load the image! String of the image name is still the argument.
      img = Resources.Load("Images/Robots/" + imgName);
      }
      
     }
 
 [...]
 
 function BuildGrid()
 {
 var kaart:Card;
 [...]
  for (k=0; k<rows; k++)
  {
    [..]
    for(l=0; l<cols; l++)
    {
     kaart = aGrid[k][l];
     //Here I point to the class variable to get the texture!
  if( GUILayout.Button(kaart.str_img) )//, GUILayout.Width(cardW)) )
  {
  Debug.Log("4. Clicked on " + k + ";" + l);
  }
    }
    [..]
  }     
 [...]
 }
