Hey I have a problem with addItem That don't add Item In Inventory i explain
If the hot bar is not empty that add It When the hot bar That dont add item directly into inventory i try it with setContents but even problem
My code

PHP:

    if($player->getInventory()->contains(Item::get(264,0,5))){
        $player->getInventory()->removeItem(Item::get(264,0,5));
$player->getInventory()->addItem(Item::get(49,0,10));
