1) are there collision groups in C2?
i would like to have certain sprites not collide with others, so they can overlap one another, while still maintaining collisions with others - like the ground. i haven't yet been able to figure this out on my own.
2) is there a way to limit rotation?
i have a limited revolute joint and had set the keys to rotate the leg pieces but once they reach the end of the range they continue trying to rotate leading to a "glitch" effect. i have since replaced rotation with applying forces but i find that doesn't simulate walking in a desirable manner. i would like to stop allowing rotation once the leg pieces reach the end of their limited revolute joint range.
here's my file i've been working on:
any help is much appreciated, thank you!
