Unity 2D Player Shoots at my joystick position


Hi I am new to unity and have only a little coding knowledge.
Right now I have made my character shoot at my touch position on mobile but when ever I touch the joystick, whick I use to move my character, he shoots there, what should I do to make him not shoot at the joystick when i hold the joystick, any suggestion… heres my code.

Shooting code

public class Shooting : MonoBehaviour
{
public GameObject shot;
private Transform playerPos;

void Start()
{
    playerPos = GetComponent<Transform>();
}
void Update()
{

        if (Input.GetTouch(0).phase == TouchPhase.Began)
        {
         Instantiate(shot, playerPos.position, Quaternion.identity);
        }
        else if (Input.GetTouch(1).phase == TouchPhase.Began)
        {
            Instantiate(shot, playerPos.position, Quaternion.identity);
        }
    else if (Input.GetTouch(2).phase == TouchPhase.Began)
    {
        Instantiate(shot, playerPos.position, Quaternion.identity);
    }


}

}

Projectile Code

public class Projectile : MonoBehaviour
{
private Vector2 target;
public float speed;
private Shake shake;
void Start()
{
shake = GameObject.FindGameObjectWithTag(“ScreenShake”).GetComponent();
target = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
target = Camera.main.ScreenToWorldPoint(Input.GetTouch(1).position);
target = Camera.main.ScreenToWorldPoint(Input.GetTouch(2).position);
}

// Update is called once per frame
void Update()
{
    transform.position = Vector2.MoveTowards(transform.position, target, speed * Time.deltaTime);

    if(Vector2.Distance(transform.position, target) < 0.2f)
    {
        Destroy(gameObject);
    } 
        
    
}
void OnTriggerEnter2D(Collider2D other)
{
    shake.CamShake();
}

}

Thanks in advance
