teleport player to playee

So, how would you teleport a player to another player?
I've defined $player1 as $sender->getPlayer();

PHP:

$player2 = $args[0];
if($player2 instanceof Player){
$player1->teleport($player2);

is this right? Or, do I have to grab player2's xyz?
if so, what if $player2 was in a different level?

 

Use this:

PHP:

 $player2 = $this->getServer()->getPlayer($args[0]);
$sender->teleport($player2); 

 

PHP:

$player2 = $this->getServer()->getPlayer($args[0]);
if($player2 !== null){
  $pos = new Position($player2->getX(), $player2->getY(), $player2->getZ(), $player2->getLevel());
  $player->teleport($pos);
}


 

No point in constructing new positions. Just do $player->teleport($player2);
