How to check the current sprite in the image source? Unity 4.6beta20

Question

Hey, so I'm making an inventory and I need to check if the image source in the image component is "Blank_Icon" which is an actual sprite. So I added the Blank_Icon sprite to the Resources and the code goes like this:

 public void AddItemToInventory(string itemName)
     {
         for (int i = 0; i < 2; i++) {
             if (invIcons[i].GetComponent<Image>() == Resources.Load("Blank_Icon")) {
                 print("Found an empty space!");
                 break;
             }
         }
     }

This doesn't work thought so how could I make it work? Thanks!

It appears you're comparing an Image class to a sprite. The Image contains a sprite, so the following should do what you want:

 if(invIcon[i].GetComponent<Image>().sprite == Resources.Load("Blank_Icon")) {

That's great but now I noticed another problem which is it doesn't work when I use Resources.Load("Blank_Icon"). It worked when I simply made a variable dedicated to the Blank_Icon. Am I loading it in wrong?

First, make sure the "Blank_Icon" is in a resources folder. I forgot about the type cast for the Resources.Load, since it returns an Object.

Updated the line with the type cast, I believe this should be right.

if(invIcon[i].GetComponent().sprite == (Sprite)Resources.Load("Blank_Icon")) {

Ah great, it was close but the actual line was

 if (invIcons[i].GetComponent<Image>().sprite == Resources.Load<Sprite>("Blank_Icon")) {

Thanks for the help!
