Given the right side of your sprite as the forward, and having a target as a Transform (your code has it as a game object), you can do it this way: Vector3 dir = target.position - transform.position; float angle = Mathf.Atan2(dir.y,dir.x) * Mathf.Rad2Deg; transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
