First of all I don't know the right terminology for the thing I need to know.
I'm sure there would be one word which describes everything I need, but because I can't, let me show you a picture of what I need :)
Here are my thoughts, how one would have to achive that:
OnCollision, I have to figure out which Body/Fixture the Terrain is. So that's easy, also to get the Point of collision is no rocket science. But now I need to know the edge on which the collision happened. From there I could get to the 2 relating vertexes.
Last, but not least, I would have to calculate the angular, which is rather easy all thanks to trigonometry.
So what actually puzzles me is how to get these 2 vertexes from the Fixture?
Or is there another way to do that, maybe even more resource-efficient?
Thank you all very much!
