File 1

PHP:

File 2

PHP:

class BuyingInventory extends CustomInventory{
     protected $client;
     protected $holder;

         public function __construct($holder,$client){
         $this->client = $client;
         parent::__construct($holder,InventoryType::get(InventoryType::CHEST),[],null,"");
     }

 

Is holder null?

 

The inventory holder is 'null' due to not being done correctly, you forgot the x,y,z in the compound tag:

PHP:

new IntTag("x", $player->getX()),
new IntTag("y", $player->getY()),
new IntTag("z", $player->getZ())


Also you forgot the types in the BuyingInventory Class:

PHP:

public function __construct(Chest $holder, Player $client){


I'm assuming those were the types you were using, feel free to correct them.

 

Yea

 

It's the full screen please stop answer for like

 

No... please why $player->getX() , $player->getY() etc. ? I have already defined -_-

 

But the problem is when I click the inventory appears and then disappears idk why

 

Or just copy it?
