Question by Jorge0117 · Sep 10, 2020 at 05:12 PM · movementcharactercontrollerfirst-person-controllerslopejittering

3D Character controller jittering when jumping against a small wall

Hello, I'm trying to make a fps controller using Unity's character controller. My character can jump 1 unit high, but when jumping against a 1unit block, the vertical movement stops.

If I change the slope limit to 90, the jittering is fixed, but if the character jumps against a wall that is 1.5 units high, the character can get on top, also, i would want to have a smaller slope limit.

I've messed around with the settings but I can't seem to fix it.

Is there a way to either avoid the jittering when using a smaller slope limit or a way to manually set a slope limit through code while setting the character controller slope limit to 90?

Thanks for your help

Setting the Step Offset to 0 or a very small value while Jumping fixes the problem. According to this thread and my personal experience: https://answers.unity.com/questions/1422941/character-controller-jitters-when-jumping-next-to.html

Yoo, this worked for me.

All you gotta do is set the stepOffset to 0 when the player jumps, and then set it back to it's default value when the player is not jumping.

No more jittering up and down.

Try making a physics material with 0 friction and putting it on the wall.
