Is GetComponentsInChildren What I'm Looking For

I’m trying to turn kinematic off so that some GameObjects will fall but I don’t know what function I’m looking for GetComponentInChildren just gets it for the first one?

	public bool IwantTheKamaticOff = false;
	Rigidbody RidgeBod;
	List <GameObject> Bricks = new List <GameObject>();

	// Use this for initialization

	void Start () {
		RidgeBod = 	gameObject.GetComponentInChildren<Rigidbody> ();
	}
	// Update is called once per frame
	void Update () {
		if (IwantTheKamaticOff == true) {
			RidgeBod.isKinematic = false;
		}
	}
}

Thanks

More likely looking for GetComponent() but I would try to speed up the process a little:

Rigidbody rigArray;

void Start()
{
     GameObject [] objs = GameObject.FindGameObjectsWithTag("RigObject");
     List<Rigidbody> list = new List<Rigidbody>();
     for(int i = 0; i < objs.Length; i++){
          Rigidbody rig = objs*.GetComponent<Rigidbody>();*

rigList.Add(rig);
}
rigArray = list.ToArray();
}
void SetKinematic(bool value)
{
for(int i = 0; i < rigArray.Length; i++ )rigArray*.isKinematic = value;*
}
This way you are only looking for the object once in the start then you have a list of Rigidbody so you can skip the gameObject level and access directly the rigidbody.
Now if you were not to remove any of those objects you would use a list instead but the process is the same. But you also need to take care of the removal to avoid null references.
