Get Player in Level in certain Gamemode

Hi!
I need code For get all player in level in survival gamemode.

Exemple:
=-=
$plw= $this->getServer()->getLevelByName($level)->getPlayers()->isSurvival(); //For exemple survival
=-=

I have test with config (set player in config and check if is on survival) and it work but exist more simple code?

PHP:

$level = $this->getServer()->getLevelByName("name");
foreach($level->getPlayers as $pl){
  if($pl->getGamemode === 0){
    //Do something
  }
}

PHP:

$survivalPlayers = array_filter(function(Player $player){
  return $player->isSurvival();
}, $level->getPlayers());


Note that it is not advisable to get a level object every time by searching it by name. It is better to cache the level ID and get the level object directly using $server->getLevel().

The most easy thinks become difficult when you write it... lol

It is actually not that hard.
