Can anyone help with shooting at mouse position on 2d game plz

Unity Engine

Edit: Ok I got the mouse position working and its working good, but the projectile is shooting out the wrong direction. Its shooting out the Z direction, when I need it to shoot out the X.

using UnityEngine;
using System.Collections;

public class Shooter : MonoBehaviour {
	
	public Rigidbody projectile; 
	public Transform shotPos;           //attatched to player
	public float shotForce = 1000f;
	public float moveSpeed = 10f;

	//Mouse Following
	private Vector3 mousePos;
	public Transform target;
	private Vector3 objectPos;
	private float angle;
	private Transform fixedRotation;


	void Update (){
	
		mousePos = Input.mousePosition;
		mousePos.z = -20; //distance between camera and object
		objectPos = Camera.main.WorldToScreenPoint (target.position);
		Debug.Log(mousePos);
		mousePos.x = mousePos.x - objectPos.x;
		mousePos.y = mousePos.y - objectPos.y;

		angle = Mathf.Atan2 (mousePos.y, mousePos.x) * Mathf.Rad2Deg;
		transform.rotation = Quaternion.Euler (new Vector3(0, 0, angle)); 

		float h = Input.GetAxis("Horizontal") * Time.deltaTime * moveSpeed;
		float v = Input.GetAxis("Vertical") * Time.deltaTime * moveSpeed;

		if(Input.GetButtonUp("Fire1")){
			Rigidbody shot = Instantiate(projectile, shotPos.position, shotPos.rotation) as Rigidbody;
			shot.AddForce(shotPos.forward * shotForce);
		}
	}
}

Thanks!! any help is appreciated.

Transform.forward is the Z direction. If you want it to fire in X, that would be Transform.right (or Transform.left, depending).
