Solved I want to make for when clicking with the item on the ground teleport to the world "LobbyA"

public function onInteract(PlayerInteractEvent $event){
$player = $event->getPlayer();
$barra = $event->getItem();
$block = $event->getBlock();
if($event->getItem()->getID() == 101){
$player->sendMessage("§eItem clicado");
$player->teleport($event->getLevel()->getName() == "LobbyA");
$player->sendMessage("§eTeleportado para o mundo §cLobbyA");
}
}

 

Why did you use $event->getLevel()?

 

$player->teleport ($this->getServer ()->getLevelByName ("lobby")->getSpawnLocation ());

 

Why to teleport for worlds use Level

 

Tank you.
