I know this question is not really related to 2D Toolkit, but is there a way to "know" which side of a box collider from a 2D sprite that was hit (top, bottom, right, left)? Since this is really basic stuff for everything, I would suspect it would be much easier to figure out.
Maybe there's a function in 2DToolkit that gives you the information about the sprite?
Been looking everywhere to find an answer but it can't seem to find it. Would it be better to just go with raycasting?
