Hi everyone,

First of all, what a lib ! Really great work @schteppe, I can't imagine what was the amount of work required to develop that library !

I've searched for answers but I didn't found anything :/ What I want to do is to lock my body rotation on axes x and z (I want to prevent my character to fall when jumping or colliding with others bodies).

Thank you for your help

I've found a solution to prevent my character falling by setting the angularDamping to 1. I can continue my game with this solution but if someone knows how to lock axes, feel free to share :)

In my character demo I'm using the body.fixedRotation = true; on the CANNON.Body character capsule. Then I'm just rotating the model attached to the capsule to my liking. In the end, an upright capsule is always a capsule, no matter how it's rotated on the Y axis, so why even bother with it. 🙂

Though maybe setting angularDamping to 1 works just as well?

I think I also started with the same idea as yours, where I wanted to lock the body on X and Z axes, but either I didn't find a solution or there was a problem with it, so I just used this.

Cool demo.

@swift502 That is a cool demo! Great job!

@swift502 awesome solution ! Just starting with game dev, capsule with 3 spheres (like in your own project) is pretty clever ! Thank you :)

As specified in this spectrum post (from pmndrs/use-cannon), it's possible to set a angularFactor in your body object to specify the dimensions you want to be available for rotation.
