Limiting Rigid Body Rotation around an axis

[TheWandererSage]

Hey, all

I'm currently working on a personal project which includes vehicles which can collide with each other. This all works fine, except that I would like to restrict the amount of rotation they can experience along a given axis. For example, I would like to prevent either vehicle from flipping over.

I saw that there's a flag which can be used to prevent rotation around an axis (specifically, the PxRigidDynamicLockFlag), but that prevents ALL movement along said axis, where I would like to limit it (e.g. to a maximum of 20 degrees along the x-axis).

I'm also aware of the existence of joints, but that feels a bit like an awkward solution, so I wanted to see whether any other mechanism exists for achieving my goal.

Thank you for any help!

Hi @TheWandererSage
As I understand it, this PxRigidDynamicLockFlag is rather for making a kind of 2D simulation by locking the extra linear and angular DOFs.
To implement some soft limits for your vehicle position and orientation, you'll use joints or apply some force/torque to the vehicle body manually. Both approaches are fine.

Thank you for the information, @vreutskyy!
I'll try the joint approach, as it seems a bit easier to control. I can probably create a joint in the middle of the physics body which doesn't take part in collisions and then have it restrict rotation.
