How do I reset the rotation of a RigidBody2D back to original rotation

Question

I have a RigidBody2D with mode Character.

Sometimes I change the mode to Rigid and let the body rotate physically.

But when I want to change the mode back to Character the rotation should also go back to 0.

How can I do it?

I'm not sure I understand your question but it sounds to my like set_rot(0) would work?!

I tried all the time changing the rotation with settransform() or setglobal_transform() and never tried it the easy way :-)

It seems set_rot(0) would do the job but when the rotation is to fast it doesn't stay on rotation = 0

I do it in this order

body.set_mode(2)
body.set_rot(0)

Is there a possibility to stop the rotation without setting mode to static?

Well, you can just set_rot(0) on both this and the next frame, right?

Answer 1

Do you mean the rotation you had before you changed the mode? In this chase you could just store the old rotation in a variable and assign it when you're changing back.

Answer 2

If you want to slowly rotate back your rigid body, then you can write something like:

# restore up rotation after collisions
var rotY=get_transform().basis.y
var rotAxis=rotY.cross(up)
var torqueAxis=rotY.cross(rotAxis)
#print(torqueAxis,rotY)
apply_impulse(torqueAxis,rotY*0.01*maxTorqueFactor)
apply_impulse(-torqueAxis,-rotY*0.01*maxTorqueFactor)

where up is a Vector2 of the up direction and maxTorqueFactor must be set to an appropriate float value...
