Nothing executed

I'm trying to make it so if player wear diamond chestplate and died it will send "L" as a message to the killer but nothing happened

public function onDeath(PlayerDeathEvent $event){

if($event->getEntity()->getLastDamageCause() instanceof EntityDamageByEntityEvent){
$killer = $event->getEntity()->getLastDamageCause()->getDamager();
$dead = $event->getEntity();

if($killer instanceof Player && $dead instanceof Player){

if($dead->getArmorInventory()->getChestplate());
$killer->sendMessage(TF::BOLD . TF:ARK_AQUA . "+L");
}
}
}

i think i'm missing something?

 

PHP:

if($dead->getArmorInventory()->getChestplate()->getId() == Item::DIAMOND_CHESTPLATE) {
 $killer->sendMessage(TF::BOLD . TF::DARK_AQUA . "+L");

}

 

that?

 

yea because your last if statement doesnt return a boolean

 

First, did you register events?
Then did you use \pocketmine\event\entity\EntityDamageByEntityEvent and \pocketmine\Player?

 

yes i did

 

PHP:

public function onDeath(PlayerDeathEvent $event) {
  $player = $event->getPlayer();
  $lastDamageCause = $player->getLastDamageCause();
  if($lastDamageCause instanceof EntityDamageByEntityEvent) {
    $killer = $lastDamageCause->getDamager();
    if($killer instanceof Player) {
      if($player->getArmorInventory()->getChestplate()->getId() == Item::DIAMOND_CHESTPLATE) {
        $killer->sendMessage("+L");

      }

    }

  }

}

 

Its true. You can try.
