Smooth ratation

Unity Engine

Hello!
Ive got this code snipped witch causes the rotation of the player to its moving direction But its not smooth the player instent rotates. How can I make it a smoother rotation?

Vector2 v = GetComponent<Rigidbody2D>().velocity;
        float angle = Mathf.Atan2 (v.y, v.x) * Mathf.Rad2Deg;
        transform.rotation = Quaternion.AngleAxis (angle, Vector3.forward);

You mean like this:

void FixedUpdate() {
        Vector2 v = rb.velocity;
        float angle = Mathf.Atan2 (v.y, v.x) * Mathf.Rad2Deg * Time.fixedDeltaTime;
        transform.rotation = Quaternion.AngleAxis (angle, Vector3.forward);
    }

´This only causes that the rotation is not working anymore.

Maybe try this.

targetRotation = Quaternion.AngleAxis (angle, Vector3.forward);
 transform.rotation= Quaternion.Lerp (transform.rotation, targetRotation , smooth * Time.deltaTime);

or try rotateTowards.

I am ebut it does not rotate

void FixedUpdate() {
        Vector2 v = rb.velocity;
        float angle = Mathf.Atan2 (v.y, v.x) * Mathf.Rad2Deg * Time.fixedDeltaTime;
    //    transform.rotation = Quaternion.AngleAxis (angle, Vector3.forward);

        float smooth = 10f;
        Quaternion targetRotation = Quaternion.AngleAxis (angle, Vector3.forward);
        transform.rotation = Quaternion.Lerp (transform.rotation, targetRotation , smooth * Time.deltaTime);    
    
    }

Maybe it’s so slow you can’t see it rotate. Put the smooth as a public at the top and change it with the editor.
Also, you should be rotating the rigidbody, I think, if you are in fixed update using physics.
