I tried to build my own collision process and got some great results.
But now I don't know how to fix the last issues I have.
The code can be downloaded here: https://github.com/EnemyArea/CollisionHandling
Feel free to use it for whatever you want.
To be more concrete, I have some issues with the jittering if there are more than two collisons at the same time.
Please take a look at this picture:
You see the two yellow circles. The circle on the bottom is the "player". Now, you would like to pass between the wall (right) and the circle (left). But the gap is not large enough. The collision system now tries to push the player back, but that cause some ugly jittering... Any ideas how I could fix that?
The next issue is, how to handle collisions when the objects are moving.
I have a circle (static) and one circle, which one is above that circle and is moving up and down. Now the player got between theese two circles and should be pushed down by the moving circle. Now the three circles stuck, because the player cant move down:
