   Staff, good staff these days Hello I was doing an inspired mcpvp called grenadier kit, it is basically a cannon, you click the right button on a slot Dispenser and poe the item that you want to launch. It is this part that enters the doubt. How to check if I do not have any item in this slot and send me a warning message saying that it has "ammo"?

   Check if the item in the clicked slot is null/air?
   

   Code:java

   if(dispenser_inventory.getItem(clicked_slot) == null) {

   Yes, and clicked_slot is, never guess, the slot clicked in InventoryClickEvent.
