Solved Problem with changing the gamemode of a player

Hey guys, I'm trying to make a plugin that changes a player's game mode when he/she goes to a certain world. But when they go to the world that is supposed to change them to creative, it changes them to survival. Anyone have any ideas? Here's the plugin:

Spoiler: Code

PHP:

use pocketmine\level\Level;
use pocketmine\event\entity\EntityLevelChangeEvent;
use pocketmine\Player;
use pocketmine\Entity;
use pocketmine\event\Listener;
use pocketmine\plugin\PluginBase;

class Main extends PluginBase implements Listener{
    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
    }
   
    public function onEntityLevelChangeEvent(EntityLevelChangeEvent $event){
        $player = $event->getEntity();
        if($player instanceof Player){
            if(!($player->isOp())){
                $target = $event->getTarget();
                if($target == "Creative"){
                    $player->setGamemode(1);
                }elseif($target == "PixelCity"){
                    $player->setGamemode(2);
                }else{
                    $player->setGamemode(0);
                }
            }
        }
    }
}

$event->getTarget() doesn't return a string.

Would
$event->getTarget()->getName()
work?

yep that worked.
Thanks @MCPEPIG
