How to make the player rotate and face the direction of movement when using AddForce (3rd Person)

I use rb.AddForce in my rigidbody movement script to move the player, the only problem is, when the player moves, it doesn't rotate towards and face the direction it is moving in. For example, if the player is moving left, it will face the forward direction while moving left, which looks awkward. I'll insert a video.

Is there any way to fix this? Please suggest me a solution, even if it requires me to change my movement code, but it has to be using rigidbodies only.

There is nothing in your code about the rotation of your character so of course it will not rotate (exept with the built in physics if it collide with someting etc.. ).

You can't handle your player rotation directly with rigidbodies, only torque. Try this to make your character face the direction he is going. you will probably need to handle the case where the speed is or close to 0.

Code (CSharp):

1. transform.rotation = Quaternion.LookRotation(rdbg.velocity.normalized, Vector3.up);

 

I tried this, but it doesn't work as expected. There's a horrible jitter and the player would start to go around in circles if I press the left or right keys.

 

Like i said, you need to handle the case where the speed is or close to 0. You can see the jitter occurs only at very low speed. Also you can avoid using the Y part of your velocity (vertical speed) to handle the jump case.
