I can't seem to figure this out. My tileset class has a tileSheet image, and I want to write a function that allows me to retrieve a tile from the tileSheet given only an index integer. The problem is, the tileSheet is a square, not a line so I have to convert the index value to X,Y coordinates. Can anyone tell me how to do this?

You have to know the width, after this, assuming x, y and the index start at 0, you have :

y = index / width (integer division)
x = index % width

That's perfect, I was pulling my hair out over that :)
It seems I always forget about that little old modulus.

Thanks man!

Edit: I would rate you up, but I already have.
