}
} 

use pocketmine\event\entity\EntityLevelChangeEvent ;

I add this but it always doesn't work

Register Listener

$this->getServer()->getPluginManager()->registerEvents(new EventListener($this), $this); ?

Yes

I add this but it always doesn't work

forgott

use pocketmine *blabla* /Level;

but u use it here if($world instanceof Level)

Any erros or what?

No just the limit doesn't work ! :s

Learn PHP. And then the PocketMine API. And how many times do we have to tell you: use a code block! And I don't know how many threads you have created regarding your "plugin", but stop, it's annoying.

Yes, assuming you have an EventListener class.
