Look at 2D Unity (object and mouse)

Look at 2D Unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class LookAt2d : MonoBehaviour {

	public GameObject target;

	void LookAtObject () {

		transform.right = transform.position - target.transform.position;
	}

	void LookAtMouse () {

		var camZ = Mathf.Abs (Camera.main.transform.position.z);
		var mousePos = new Vector3 (Input.mousePosition.x, Input.mousePosition.y, camZ);
		mousePos = Camera.main.ScreenToWorldPoint (mousePos);
		transform.right = (transform.position - mousePos);
	}

	void Update () {
		//LookAtObject ();
		LookAtMouse ();
	}
}

Awesome using "transform.right" to set the direction haha
