How to Properly Move Two Attached Kinematic Rigidbodies
I have a player character, which has a kinematic rigidbody since it's controlled by a script.
The player character carries an axe, which has a rigidbody that I set to kinematic when I need to move it based on player input, otherwise it is non-kinematic and attached to the player's kinematic rigidbody with a fixed joint.
Questions:
if I want to move or rotate the player character to some position (i.e. they step into a trigger and I want a script to temporarily take control) I know I need to move the rigidbody with MovePosition and MoveRotation - do these functions need to be called in FixedUpdate since these are physics functions? Or does it not matter since it's a kinematic rigidbody?
similar for the axe, when I set it to kinematic to move/rotate it with a script, does that movement/rotation need to happen in FixedUpdate?
when its time to un-holster the axe from its shoulder position and move it with player input, I set the axe's rigidbody to kinematic and let a script take over its movement and rotation - do I also need to break the fixed joint that attaches the axe to the shoulder position? would my script be fighting its physics in any way if I didn't?
lastly, if all this needs to be happening in FixedUpdate, do the coroutines that execute MovePosition and MoveRotation need to yield WaitForFixedUpdate? or can they yield null?
Thanks!
since questions are more frequently answered in the forum rather than here on Answers, I've asked the same question there and have gotten some traction - https://forum.unity.com/threads/properly-moving-two-attached-kinematic-rigidbodies.1220541/#post-7808790
