i started to make a 2d game a while ago and i encountered a lot of Problem with movment and gravitation.
I managed to make sure, that stuff can't get through walls (Line-Collision System, with the Separating axis T.) But after that the Problems started and i desparating right now. first i had the Problem with tzhe Gravitation, that when you stand on a inclined line and Gravity is on, the Player slowly slides of the surfaces. also if you move on an inclined line you are slower than you were on even surface. next Problem is, that if you move in the opposite direction of an inclined line, you just fly in the air for a brief second. There are a lot of other Problems but i don't wanna list them all here.
Does someone have a few links for me?
