pmmp error (I have this error on the console)

error:::[Server thread/CRITICAL]: pocketmine\plugin\PluginException: "pocketmine\event\entity\EntityDamageByEntityEvent does not have a handler list" (EXCEPTION) in "/src/pocketmine/plugin/PluginManager" at line 790

my code:::

PHP:

    public function pvpNintendoElDevPro(EntityDamageByEntityEvent $event){
        $killer = $event->getDamager();
        $world = $killer->getLevel()->getName();
        $mundos = $this->getConfig()->get("mundos");
        if(in_array($world, $mundos)) {
            if ($killer instanceof Player) {
                if($killer->getItemInHand()->getId() === 276){
                    $event->setCancelled(false);
                }else{
                    $event->setCancelled(true);
                }
            }
        }
    }

 

I believe you need to use EntityDamageEvent, then check if it is an instanceof EntityDamageByEntityEvent.

 

Thank you very much, I function
