Solved EntityDamageByEntityEvent Error

Here is the code:

PHP:

  public function onHurtCMode(EntityDamageByEntityEvent $event){
      $hurter = $event->getDamager();
      if($hurter->getGamemode() == 1){
        $event->setCancelled(true);
        $hurter->sendMessage(TextFormat::RED . "No creative mode killing please!");
    }
}

And here is the error:

PHP:

Could not pass event 'pocketmine\event\entity\EntityDamageEvent' to 'EventHandler v1.0.0': Argument 1 passed to EH\Main::onHurtCMode() must be an instance of pocketmine\event\entity\EntityDamageByEntityEvent, instance of pocketmine\event\entity\EntityDamageEvent given, called in phar:///root/PocketMine-MP.phar/src/pocketmine/plugin/MethodEventExecutor.php on line 36 and defined on EH\Main


This error showed when a player with c-mode killed someone...

PHP:

public function onHurtCMode(EntityDamageEvent $event){
      $cause = $event->getEntity()->getLastDamageCause();
      if($cause instanceof EntityDamageByEntityEvent){
      $hurter = $event->getDamager();
      if($hurter->getGamemode() == 1){
        $event->setCancelled(true);
        $hurter->sendMessage(TextFormat::RED . "No creative mode killing please!");
    }
}
}

Thanks!!!
