RigidBody.MovePosition

Unity Engine
1

I’m having problem with the function RigidBody.Moveposition , it just doesn’t move if the rigidbody is to kinematic , I checked the documentation but didn’t find anything there either , am I missing something??

What’s the code?
Did you attached the script to the GO?

of course I did attach the script to the game object

Ignore the gravity part it just returns a vector3 in required direction.
even if it was buggy I tried same thing thing without it and setting the isKinematic to true in the inspector and the rigidbody stopped moving suddenly , I don’t know what’s causing this at all:face_with_spiral_eyes::rage::rage:

Start slapping Debug.Logs in there to see what it’s doing, make sure that p_FinalVelocity actually has the value you think it has.

yes it has that velocity it moves fine when not kinematic but as soon as I make it kinematic it just stop,I’m really getting frustrated over this, I mean MovePosition are mainly for kinematic bodies then what the heck is wrong with this???:rage::rage:

I found out something interesting , I’m able to call MovePosition only once per fixed update from my script,is this officially documented somewhere???:eyes:
