Solved How to detect item taken from chest

How to detect item taken from chest?
I want to cancel it and remove taken item

 

Use InventoryTransactionEvent. When it gets cancelled, the Item doesn't get moved so you won't need to remove the Item once you've already cancelled the event.

PHP:

/** @var InventoryTransactionEvent $event */
foreach($event->getActions() as $action){
    if($action instanceof SlotChangeAction){
        $inventory = $action->getInventory();
        if($inventory instanceof ChestInventory){
            $theItemThatPlayerClicked = $action->getSourceItem();
            //^that is the item that the player clicked.
            //cancelling the event will disallow player from moving the item anywhere.
            $event->setCancelled();
            break;
        }
    }
}


 

thank you

 

I want to prevent specific item from being put in the chest
Can you give an example function please? @Muqsit

 

$theItemThatPlayerClicked is an instance of the Item class. You can use something like this to prevent player from transferring dirt to their inventory.

PHP:

if($theItemThatPlayerClicked->getId() === Item::DIRT){
    $event->setCancelled();
    break;
}


 

Here is my code but its not working

PHP:

public function onInventoryTransaction(InventoryTransactionEvent $event) {
        $player = $event->getTransaction()->getSource();
        foreach($event->getTransaction()->getActions() as $action){
            if($action instanceof SlotChangeAction){
                $inventory = $action->getInventory();
                if($inventory instanceof ChestInventory){
                $theItemThatPlayerClicked = $action->getSourceItem();
                    if($theItemThatPlayerClickedget->getId() == 2){
                        $event->setCancelled();
                        break;
                    }
                }
            }
        }
    }

 

typo:
...
if($theItemThatPlayerClickedget->getId() == 2){
...
