How can I modify this code to work this way.
if the item that will be added to the player has property (isStackable()) it will not autostack if the item is added to any container of the player, or arrow slot or in both hands, but if the item is added and there is no empyt slot in the player's container, when the item falls to the ground it autostacks if it has another item like it.
basically I would like the item to only stack on another item if it falls to the ground when added to the player.
can anybody help me? Thank you very much in advance
