Solved What im doing wrong?

I use this code...

PHP:

    public function Death(EntityDamageEvent $event) {
        $player = $event->getEntity();
        if (!$player instanceof Player) return;
        switch ($event->getCause()) {
            case EntityDamageEvent::CAUSE_ENTITY_ATTACK:
                if ($event instanceof EntityDamageByEntityEvent) {
                    $damager = $event->getDamager();
                    if ($damager instanceof Player) {
                        if ($event->getFinalDamage() >= $player->getHealth()) {
                            $event->setCancelled(true);
                            $this->plugin->getServer()->broadcastMessage(Color::RED.$player->getName()." §eHe has been killed by ".Color::GREEN.$damager);
                            $player->getInventory()->clearAll();
                            $player->getCursorInventory()->clearAll();
                            $player->getArmorInventory()->clearAll();
                            $player->setHealth(20);
                            $player->removeAllEffects(true);
                            $player->teleport($this->plugin->getServer()->getDefaultLevel()->getSafeSpawn());
                        }
                    }
                }
            break;
        }
    }

But when i kill the player/do the final hit nothing happens...

I really appreciated a help

 

if ($event->getBaseDamage() >= $event->getEntity()->getHealth())

 

haha. I'm stupid, forget to import: use pocketmine\Player;
