I need a script that would make it so whenever a sprite hits a surface it calculates the angle of the surface, please tell me asap. (:

That's quite hard. You basically want to find a tangent to a given surface, right? Well, the solution is to find two points close together on the surface, and use them, plus some trig, to find the angle.

Hardmath's right. This is very hard to achieve. There is, however, a method of switching to a 1px costume and pointing in direction 0 delete all of vals, repeat 360 move 1 step, if touching (edge) add [1] to [vals v], move -1 steps, turn right 1 degree

You'll need to put that script after repeat 360 360 times in a row O.O

Then, it's all trig from there. smile

Well, depending on the accuracy, you could make do in 20-ish repetitions.
