I've encountered a problem in my attempt to implement Collision Handling for a game I'm creating, involving a collision with two angled platforms.
I'm using GJK-EPA for detecting/handling collisions so I can pull the penetration vector and depth from each collision, and using this I have been calculating the angle of the surface the player collides with.
What I don't understand, is how I should resolve a collision when the character is moving from one slope to a steeper slope, one slope to a shallower slope and flat-surface -> slope and vice versa.
I attempted comparing penetration depths but due to the nature of GJK, I can only do this with some additional vector maths which then refuses to work for steep->shallow slopes. Additionally: It sometimes seems to 'spasm' on direct contact with vertices.
Basically, can anyone tell me a good/common way of handling angles of objects that are touching TWO platforms, using GJK-EPA?
(To note: I'm relatively new to game development, and I'm trying to get some smooth slope physics working, just so you know the 'situation').
