Hello Everyone,
I am currently making an app that involves sprite images of a square with a different color on each of the four sides, there are seventy of them that fill the iphone screen. You have to rotate one sprite to match one side color to another sprite side color below it or next to it. I can rotate the sprite, but I was wondering if someone could show me an example of how to check if a particular side of a sprite is touching another particular side of another sprite, and how to make sure that there is matching touching sides until it reaches from one side of the screen to another.
