Chill If you just want to hide your skeleton's hand, I think it could be accomplished by simply setting the attachment to be displayed in the hand slot to null using the set_attachment() method, like this:
get_skeleton().find_slot("hand").set_attachment(null);
Currently there is no method to easily change the draw order, it may be faster to prepare an animation with a key of the changed draw order and play it on a higher track.
