Solved Teleportation using Position.php sucks :/

I have class Arena.php and Main.php in Main.php I am registering
spawns etc

PHP:

public function onEnable(){
$this->setArenasData();
}

public function setArenasData(){
    $this->areny["TowerFall"] = ['lobby' => new Position(-16, 181, 0, $this->getServer()->getLevelByName("mm-towerfall")),
        'level' => $this->getServer()->getLevelByName("mm-towerfall"),
        '1spawn' => new Vector3(7, 142, -4),
        '2spawn' => new Vector3(23, 142, 10),
        '3spawn' => new Vector3(9, 151, 13),
        '4spawn' => new Vector3(21, 151, 21),
        '5spawn' => new Vector3(16, 151, 6)];
}

in class Arena.php
I have in constructor

PHP:

/** var Main $plugin */
$this->data = $plugin->areny[$id];


It make me able to get something from $this->areny in Arena.php
now I trying to teleport player like this:

PHP:

$player->teleport($this->data['lobby']); // new Position(-16, 181, 0, $this->getServer()->getLevelByName("mm-towerfall");


Player get teleported, but he dont move to world "mm-towerfall" it only teleport him to coords -16, 181, 0

I tried to teleport player using Position.php without getting position from $this->data and it worked perfectly, so what is bad?

PHP:

$player->teleport(new Position(-16, 181, 0, Server::getInstance()->getLevelByName("mm-towerfall"))); //Working :v


Level mm-towerfall is 100% loaded.

 

You suck at passing a Position parameter to Entity::teleport() :/
Send the output of var_dump($this->data["lobby"])

 

Code:

object(pocketmine\level\Position)#11192 (4) {
  ["level"]=>
  NULL
  ["x"]=>
  int(-16)
  ["y"]=>
  int(181)
  ["z"]=>
  int(0)
}

I do not understand why level is null, it is loaded

 

Before calling setArenasData(), var_dump(Server::getInstance()->isLevelLoaded("mm-towerfall"))

 

Ah, it happened because I called $this->setArenasData() before I loaded the world
