    void Start()
    {
        coll = GetComponent<Collider>();
        coll.isTrigger = true;
    }

    // Disables gravity on all rigidbodies entering this collider.
    void OnTriggerEnter(Collider other)
    {
        if (other.attachedRigidbody)
            other.attachedRigidbody.useGravity = false;
    }
