How to get a "list" from config?

Hi. How may I will get a list from config?
Example, this is my config:

Code:

worlds:
- "Survival"
- "FFA" 

This is my main:

PHP:

public function playerChange(EntityLevelChangeEvent $event){
        $player = $event->getEntity();
        $worlds = $this->worlds->get("worlds"){//$this->worlds is config.yml


But it doesn't works. Help plz

 

PHP:

public function playerChange(EntityLevelChangeEvent $event){
        $player = $event->getEntity();
        $worlds = $this->worlds->getNested("worlds");
}

 

If I understand correctly you want to take the array of your world from your config and use them only on this world if I'm wrong on your question.
Try:

PHP:

 public function onLevelChange(EntityLevelChangeEvent $event){
        $entity = $event->getEntity();
        $worlds = (array) $this->worlds->getAll()['worlds'];
        if(in_array($entity->getLevel()->getFolderName(), $worlds)){
            //continue your code ...
        }
    }

 

Code:

worlds:
- Lobby
- Totem

PHP:

$level = $config->get("worlds");
foreach($level as $worlds){

}
