Hello, about compute two angle of Quaternion between angle

Unity Engine

how can compute two values of the angle of Quaternion (StartAngle,EndAngle) between angle( also angle of Quaternion )?

This is my previous code：

    public Vector3 My_Rotation01 = new Vector3(0f,180f,0f);     //save target angle

    public Vector3 StartAngle;      //will save current angle

	void Start () {



        

        StartAngle = transform.rotation.eulerAngles;//// saveing current angle





	}
	

	void Update () {


        transform.rotation = transform.rotation * Quaternion.Euler((My_Rotation01 - StartAngle) * Time.deltaTime);       


	}

but,This would often calculation error：
e.g. “0° → 20°” will become “0° → 340°”

So, I would like know there a better way?

Thank all :smile: :smile: :smile:

If you have the start and end rotations as quaternions, you can use Quaternon.Slerp to interpolate between them.
