I want the rayCast to register all hits except the ones on the player
The player is on Player layer. I used a layerMask and selected all layers except the player but that dint work heres the code im using:

IEnumerator Shoot()
    {
        RaycastHit2D hit = Physics2D.Raycast(shootOrigin.transform.position , shootOrigin.transform.right , layerMask);
        if(hit)
        {
                Debug.Log(hit.transform.name);
                Enemy enemy = hit.transform.GetComponent<Enemy>();
                if (enemy != null)
                {
                    enemy.TakeDamage(damage);
                }

                lineRenderer.SetPosition(0, shootOrigin.transform.position);
                lineRenderer.SetPosition(1, hit.point);

        }
        else
        {
            lineRenderer.SetPosition(0, shootOrigin.transform.position);
            lineRenderer.SetPosition(1, shootOrigin.transform.position + shootOrigin.transform.right * 100);
        }
        lineRenderer.enabled = true;
        yield return new WaitForSeconds(0.02f);
        lineRenderer.enabled = false;
    }

Let the player on the default layer, put the enemy on a new layer “Enemy”, put layerMask value as “Enemy” layer… just that
