unit – Unity5 Rotation / Orientation Boxcast

How do you shoot a boxcast broadcast and stay focused on its parent game object?
This is my code:

                float m_MaxDistance;
Collider m_Collider;
bool m_HitDetect;
RaycastHit m_Hit;

void Start () {m_MaxDistance = 144.0f; }

void FixedUpdate () {
m_HitDetect = Physics.BoxCast (m_Collider.bounds.center, new vector3 (transform.localScale.x / 2, transform.localScale.y / 2, 0.5f), transform.forward, m_Hit, Quaternion.LookRotation (transform.forward), m_MaxDistance);
}

Thank you
