not sure what to set the subject at, but I was wondering if there's an easy way to set the collision for a sprite to the pixels that are not transparent.

Take this image for an example:

I want the "sprite collision(1, 2) = 1" to return the value 1 only if the orange pixels are hit by anything, and not the transparent background. Is their any easy way to do this?

(I'm using .png's right now, Haven't gotten into keying a special color out yet)

You could try looking up "pixel perfect" sprite collision but unless it's really necessary it'll slow your game down I believe. Depends what you use it for I guess...
