how to make a object rotate towards a position in 2d unity
Vector3 targ = staticCompassTarget.transform.position;
targ.z = 0f;
Vector3 objectPos = transform.position;
targ.x = targ.x - objectPos.x;
targ.y = targ.y - objectPos.y;
float angle = Mathf.Atan2(targ.y, targ.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle));unity rotate vector
Vector3 rotated = Quaternion.AngleAxis(-45, Vector3.up) * vector;unity 2d rotate towards direction

//get the direction of the other object from current object
Vector3 dir = target - transform.position;
//get the angle from current direction facing to desired target
float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
//set the angle into a quaternion + sprite offset depending on initial sprite facing direction
Quaternion rotation = Quaternion.Euler(new Vector3(0, 0, angle + offset));
//Roatate current game object to face the target using a slerp function which adds some smoothing to the move
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, RotationSpeed * Time.deltaTime);
