ya deja de funcionar bien. alguna idea de como cambiar que siga el mouse, y siga mi personaje?

 using UnityEngine;
using System.Collections;
public class Apuntar : MonoBehaviour {
public GameObject objetivo;
void Update () {
Vector2 pos = objetivo.transform.position - transform.position;
float rot_z = Mathf.Atan2(pos.y, pos.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rot_z);
}
}
