Как отключить и обеспечить единство жесткого тела
// if you want to disable the rigidbody on which the script is sitting on
// you can't do that but you can go around it by
// Just destroying the rigidbody by calling
Destroy(gameObject.GetComponent<Rigidbody>());
// and if you want it again call
gameObject.AddComponent<Rigidbody>();
// Remember "gameObject" with small 'g' reffers to the gameObj on which the script
// is sitting on
