please, send the code in the line 54.

you should use:

PHP:

$item = $e->getPlayer()->getInventory()->getItemInHand();



 

PHP:

$item = $player->getInventory()->getItemInHand(); //Line 53


 

Please send us your whole code, where do you define $player?

 

Why use getItemInHand() in PlayerInteractEvent? Just use $item = $event->getItem();
