Another collision detection issue...

[fawfulfan]

I was wondering...is it possible for an object with lots of sprites to be set so that only one spite acts as a collision mask? For instance, if there's one small sprite, but lots of large sprites, can you set it so that no matter what frame is playing, collisions are detected as though it's continuously on the small sprite?

Sort of... there's a trick to it that involves making events forcing the animation frame to the one that you want to detect collisions with, then doing any collision events, then setting the animation back to where it was. As far as the game logic is concerned, the object was on that frame during the collision check, but the player doesn't notice because the frame is redrawn only after the event list has been run through.
