If Damage Reason Is Fall Damage Then Do This

I am trying to get when a player takes fall damage while wearing a mask(Special Armor). If they take damage I want them to get the Effect Night Vision.

PHP:


public function onDamageByOther(EntityDamageEvent $event){
    $player = $event->getEntity();

    $isFall = $event->getCause() === EntityDamageEvent::CAUSE_FALL;
    if($isFall){
        if($player instanceof Player){
            if($player->getArmorInventory()->getHelmet()->getId() === 86){
                $player->addEffect(new EffectInstance(Effect::getEffect(Effect::NIGHT_VISION), 2147483647, 1, false));
            }
        }
    }

    if($player instanceof Player){
        if($player->getArmorInventory()->getHelmet()->getId() === 86){
                $player->addEffect(new EffectInstance(Effect::getEffect(Effect::NIGHT_VISION), 2147483647, 1, false));
        }
    }
}


Any Help would be great thank you!!!

86? 86 isn't guaranteed to be any item's ID. Use Item::DIAMOND_HELMET or something instead. Also, check your imports.
