I have made a basic first person character controller, and I'm having some trouble with the collision shape in game. I originally used a cylinder because it made it easy to change the height and have the player duck. I didn't really have any issue until I put it into a level with some uneven terrain and noticed the character would get stuck on certain slopes and at weird angles. I've tried to switch it to a capsule shape and that seemed to help with the weird collision on the ground, but now when I change the height of the capsule past a certain point it also changes the radius which is unwanted. I'm wondering if there's any good way to get around this? Which shape is better? I would use a capsule if it didn't limit the height which I could use, but then with cylinder I'm having weird collisions. I've tried messing with different settings, but haven't really found a decent solution. Appreciate if anybody could provide some guidance.
Normal height with capsule:
Height adjusted for player crouching and radius is automatically adjusted (player becomes too small):
Cylinder with correct shape (but gets stuck on uneven terrain):
I guess I'm wondering if there is any way to get a capsule shape which is similar shape to the cylinder in the last picture?
