Created prefab follows player instead of being fixed to the world

I'm instantiating a health bar prefab and it loads into the scene perfectly fine but it moves relative to my player object. I need it to spawn at a static location/position in the world. It is also inside a canvas.

private void OnMouseDown()

    {

        GameObject hb = Instantiate(HealthBarPrefab, new Vector3(50, 50, 0), Quaternion.identity);



        hb.transform.SetParent(GameObject.FindGameObjectWithTag("Canvas").transform, false);

    }

Is there something wrong with this part of the script that would make it move relative to the player?

 

The code you provided does not indicate any such behavior, the problem must be somewhere else in your code.
