Problem with shooting while player moves (third person)

So I have player(just a rolling cube) w$$anonymous$$ch can shoot bullets, the player has a script for the shooting:

 if(Input.GetKeyDown(pc.kc.keys.attack1))
         {
             Ray ray = pc.cam.ViewportPointToRay(new Vector3(0.5F, 0.5F, 0));
             RaycastHit $$anonymous$$t;
             if (Physics.Raycast(ray, out $$anonymous$$t, Mathf.Infinity, ~ignoreLayers))
             {
                 GameObject p = Instantiate(projectilePrefab, transform.position, transform.rotation);
                 p.GetComponent<Rigidbody>().velocity = pc.rb.velocity;
                 p.GetComponent<ProjectileController>().cm = t$$anonymous$$s;
                 p.GetComponent<ProjectileController>().damage = damage;
                 p.GetComponent<ProjectileController>().force = projectileSpeed;
                 p.GetComponent<ProjectileController>().target = $$anonymous$$t.point;
                 Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * $$anonymous$$t.distance, Color.yellow);
             }
             else
             {
                 GameObject p = Instantiate(projectilePrefab, transform.position, transform.rotation);
                 p.GetComponent<Rigidbody>().velocity = pc.rb.velocity;
                 p.GetComponent<ProjectileController>().cm = t$$anonymous$$s;
                 p.GetComponent<ProjectileController>().damage = damage;
                 p.GetComponent<ProjectileController>().force = projectileSpeed;
                 p.GetComponent<ProjectileController>().target = pc.cam.transform.position + (pc.cam.transform.forward * 1000);
                 Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 1000, Color.w$$anonymous$$te);
             }
         }

But when I move/roll the player and shoot at the same time the bullets go everywhere. I tried almost everyt$$anonymous$$ng and can't find any solution, my player is moving pretty fast and when my player doesn't move it works perfectly find.

Help appreciated.
