how to get the level object knowing only the name of the world?

Hi , i' m new on the forum and that is my first thread if something is not written correctly is because i' m not english

I need an help with that :

PHP:

public function isGameFull($levelName){                    
           if($this->config->get("MaxPlayersPerGame") == count($this->getServer()->getLevelByName($levelName)->getPlayers())){
               return true;     
           }else{
               return false;
           }        
    }

when that function is called the server crash, reason: call to a member function getPlayers() on NULL
why ? I would appreciate if someone reply ,thanks to all

getPlayers -> getOnlinePlayers

You can also just use

PHP:

return $maxPlayers === $otherMax;
// You have to replace/define them

instead of if/else.

you' re right but the error is the same...

PHP:

       public function isGameFull($levelName){                   
           return $this->config->get("MaxPlayersPerGame") === count($this->getServer()->getLevelByName($levelName)->getPlayers());  
    }

...Call to a member function getPlayers() on null

Wt, do you know what you're saying?

@Svile check $levelName's value.

I tried to enter the level name string :

PHP:

public function isGameFull($levelName){                  
           return $this->config->get("MaxPlayersPerGame") === count($this->getServer()->getLevelByName("lobby")->getPlayers()); 
    }

nothing change ... the level folder is in her place and is called "lobby"... i really don' t know why this error appears

1. Make sure $levelName is "lobby".
2. Make sure the world is loaded.
3. Make sure the world name not just the world folder name is lobby.

solved by loading the level in memory ... Thanks
