Is it possible to "easily" rotate an object "to face" the direction of its movement?

Question

Game development

The object has a front side, how to make it move "face" in the direction of movement when it bounces against the walls.
"easy" - it means that it is not possible to calculate the "target direction vector" or let heaven, etc. body movement (because I did it and I don’t like it), but let’s say the rigidbody already has a ready-made function (it also calculates the rebound), use it.

Answer 1

Take Rigidbody.velocity and stuff it into Quaternion.LookRotation , you get the desired rotation that you can apply to your graphics transform.
