3D RigidBody: How to change rotation.y by code?

Question

Hi...,

I have a 3D RigidBody with a locked Y-Rotation-Axis (Axis Lock Angular Y). All other linear and angular axes are unlocked.

I want to set the y-rotation by code myself. The translation and rotation of the unlocked axes should be calculated by the physics engine.

I can change rotation.y in _physics_process(delta) or _process(delta), which rotates in y correctly, but this stops the translation and rotation of the unlocked axes, calculated by the physics engine. Another try to change the translation in _integrate_forces(state) doesn't do anything.

Any ideas?

Thanks

Mike

Hi,
use the RigidBody mode "character"
then modify the transform in the bodystate

func _integrate_forces( state ):
    state.transform.basis = state.transform.basis.rotated(Vector3.UP,the_rotation)

Comments

Hi klaas,

state.transform.basis = state.transform.basis.rotated(Vector3.UP,the_rotation)

fixed my problem. I leave the mode as Rigid and not Character, because I need the automatic physics rotation in x, and z.

Thank you so much, I've learnd something new, and I think I like Godot more and more, Cheers

Hi i am new to godot and i have done this but after a few rotation my input keys wont work.

Hi,
this issue seems to be related to another problem.

Can you provide code to replicate the issue?

Thanks so much for the answer! I was struggling with rotating a rigidbody as it wasn't rotating around its own axis. Your solution works.
