        $sender->getInventory()->addItem(new Item(259, 0, 1));

}

I'm guessing I don't have one of the correct classes to use but I don't know which one

 

Armor and Player inventory has been separated. You can affect armor inventory by getting player's ArmorInventory object.

Fix this by using this:

PHP:

$sender->getArmorInventory()->setContents($items);


To simply put it: Your code was outdated.

Cheers!

 

Thanks! That worked perfectly, I had been looking at the forums from 2014 guess that's not a great idea after 6 years of updates
