Solved Cancelling PlayerInventoryClickEvents while in a specific container

So I want to make a GUI which players can click on, but you can put stuff in there. Even after replacing all empty slots with glass, players can still shift-click items which the same metadata into the GUI.

Here is my code for now

Code:

@EventHandler
public void event(InventoryClickEvent event) {
if (event.getClickedInventory().getHolder() instanceof RecipesGUI) {
event.setCancelled(true)
}
}

However, this only stops moving of items in the inventory, not the players inventory. So how can I cancel player's inventory while in that GUI?

Thanks

This would probably allow you to do something like this

Code:

@EventHandler
public void event(InventoryClickEvent e){
  if(e.getPlayer().getOpenInventory().getTopInventory().getHolder() instanceof RecipesGUI) event.setCancelled(true);

}

The code above is not tested but the concept should be there?

Also I'm a bit confused here... why is the RecipesGUI an InventoryHolder?

 

Thanks so much! Solved!

btw its event.getWhoClicked()
