# SendBodyUpdateCallbacks()

> Send all current _bodyUpdateEvents where the PhysicsBody involved are valid (see _isValid ) and have a callback target assigned (see _callbackTarget ). Only callback targets that implement PhysicsCallbacks.IBodyUpdateCallback will be called. This will be called automatically if _autoBodyUpdateCallbacks is true. This must be called on the main thread.
