Remove 1 item from item in hand

Im trying to remove 1 emerald from a players hand. He may have a stack of 6 forexample but when i run:

Code:

$player->getInventory->removeItem(new \pocketmine\item\Emerald(0,1));

it takes the whole stack.

Pls help

 

Do not create a new item class in that way. Always use

PHP:

Item::get(Item::EMERALD, damage, count);


You almost made it!

PHP:

$player->getInventory()->removeItem(Item::get(Item::EMERALD, 0, 1));


 

Thanksss
