What's wrong?

No errors, just won't work. I want it to announce how many pots the player has left on killing event.

PHP:

<?php
namespace HMR;

use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\utils\TextFormat;
use pocketmine\event\player\PlayerDeathEvent;
use pocketmine\event\entity\EntityDamageByEntityEvent;
use pocketmine\Player;
use pocketmine\Server;
use pocketmine\math\Vector3;
use pocketmine\command\ConsoleCommandSender;

class Main extends PluginBase implements Listener{
    

    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this,$this);
        $this->getLogger()->info(TextFormat::BLUE . "HealthMessageReturn Enabled!");
    }

    public function onDeath(PlayerDeathEvent $event) {
  
        $cause = $event->getEntity()->getLastDamageCause();
        if($cause instanceof EntityDamageByEntityEvent) {
            $player = $event->getEntity();
            $killer = $event->getEntity()->getLastDamageCause()->getDamager();
            if($killer instanceof $player){
              $item = $killer->getInventory()->getContents();
              $itemId = $item->getId();
              if ($itemId === "438:22") {
                $count = $item->getCount();
                $this->getServer()->dispatchCommand(new ConsoleCommandSender(), "sm * §4".$player->getName()." §r§chas been annihilated by the one and only§4 ".$killer->getName()."§4[❤ ".$killer->getHealth()." HP - ".$count." Pots]§r§c.");
              }
            }
          }
        }
    }

}


 

The function getInventory()->getContents() returns an array, not an item.

 

Okay, could you please give an example?

 

I'm sure you can find an example without any help... Just loop through the array and count how many items have the ID.

 

Okay, thank you for your help.
