Question by dINGLE · Aug 14, 2017 at 07:40 PM · physics controller force

How can I control rigidbody velocity direction using forces?

I have a rigidbody moving in a direction, and I would like to change the direction of movement to a desired direction using forces. For example: My rigidbody velocity is (0,0,1) and I want to change it to (0.5,0,0.5)

I don't want to set the velocity directly because that would cause issues when it comes to collisions etc.

Is there some 'PID' like controller code to do this? I have searched but haven't found any

PID should work fine. If you don't have drag or anything, PD is fine. If you do have drag, I'd use PIDF.

Hi, thanks, do you know of sample code for one of those for 3 axis?
