I would like to see a new built-in feature that will allow me to determine what side of a bounding box is overlapping. This may be confusing, so here is an example:
Say X is a mob, and Y is something it is not supposed to be on. Now, if I run a check and see that X is overlapping Y via bounds_dist(), then I can catch X...but I can't do much about it. My first thought would be to modify it's step_x and step_y to shove it off, but I don't know which way to shove it. If X is overlapping Y's right side by 3 pixels, I want add 3 to X's step_x. I have no good way of figuring out that information, though.
This is why I would like something along the lines of bounds_side(a, b) (Although I'm not the best name-maker around), that will tell me which side of b a is overlapping.
