Solved Disable PVP in certain worlds?

How i can disable PVP in certain worlds? Thanks.

Use plugin PvPWorlds by @Samueljh1

Thank you! <3

PHP:

public function onHurt(EntityDamageEvent $e){
    if($e instanceof EntityDamageByEntityEvent && ($entity = $e->getEntity() instanceof Player) && $e->getDamager() instanceof Player && $entity->getLevel()->getName() == "world"){
        $e->setCancelled();
    }
}

PHP:

$e->setCancelled();


has to be :

PHP:

$e->setCancelled(true);


it doesn't matter

It would still be the same thing!

I prefer use setCancelled(true). It sounds better xD
