Solved Effect Not Working

Ok I Am Trying To Give A Player A Effecf When They Hit A Player But It Isnt Working..... Here Is My Code

PHP:

ublic function onHurt(EntityDamageEvent $event){
   
$entity = $event->getEntity();
if($event instanceof EntityDamageByEntityEvent){
if($event instanceof Player){
$killer = $event->getEntity()->getLastDamageCause()->getDamager();
$cause = $event->getEntity()->getName();
if($event->getDamager()->getInventory()->getItemInHand()->getId() === 272){
                $event->getEntity()->addEffect(Effect::getEffect(10)->setAmplifier(1)->setDuration(6000)->setVisible(false));
    }
    }
    }
    }

$event won't be instanceof Player.

Use this instead of $event->getEntity()->addEffect(Effect::getEffect(10)->setAmplifier(1)->setDuration(6000)->setVisible(false)); (This wouldn't work anyways...) EDIT: It works

$effect = Effect::getEffect(10);
$effect->setAmplifier(1);
$effect->setDuration(6000);
$effect->setVisible(false);
$entity->addEffect($effect);

It has no difference with $entity->addEffect(Effect::getEffect(10)->setAmplifier(1)->setDuration(6000)->setVisible(false));

Oh...

so wat do i do...

Nvm Fixed It
