Dranik said: is there a way that when you use an item: %{selected\repeating_item_$x-roll} caused the quanity of same item to be reduced by 1? sound like a simple use of the ammo track on the companion script api just a matter of setting the item up as a resource and the item using it, to use the resource. like arrows and the longbox for example. the item arrow is set to be ammo and the longbow is set to use the arrow ammo. so each click on longbow reduces the resource arrow by -1.
