[b]Note:[/b] Don't change a RigidBody3D's position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed Hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop may result in strange behavior. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state. If you need to override the default physics behavior, you can write a custom force integration function. See [member custom_integrator]. + With Bullet physics (the default), the center of mass is the RigidBody3D center.
