WHY? - Loading Levels:

Hi, i keep getting this error for some reason:

PHP:

Fatal error: Call to a member function getChunk() on null in phar:///Users/samuel/PluginDevs/PocketMine-MP.phar/src/pocketmine/level/Level.php on line 2039


The Question is WHY?

Here is the whole function:

PHP:

public function restartGame(){
      
        $this->P1 = 0;
      
        $this->id = 1;
      
        $this->RJ = [];
      
        $this->pid = [];
      
        $this->starting = 0;
              
        $this->winner = "";
      
        $this->Sign1 = $this->lobby->getTile(new Vector3(-10,6,151));
        $this->Sign2 = $this->Sign1; //$this->lobby->getTile(new Vector3(-11,6,151));
      
        $this->Sign1->setText("[Join]","******",$this->mapn,0 . "/4 Players");
        $this->Sign2->setText("[Join]","*******",$this->mapn,0 . "/4 Players");
      
        $this->players = array();
      
        $this->started = 0;
      
        $this->deleteDir(Server::getInstance()->getDataPath() . "worlds/" . $this->tmn);
      
        $this->cpr(Server::getInstance()->getDataPath() . "worlds/" . $this->omn,Server::getInstance()->getDataPath() . "worlds/" . $this->tmn);

        $this->map = Server::getInstance()->getLevelByName($this->tmn);
      
        Server::getInstance()->unloadLevel($this->map);
      
        Server::getInstance()->loadLevel($this->tmn);
      
        $this->map = Server::getInstance()->getLevelByName($this->tmn);
      
    }


I can get this to work in the onEnable() function:

PHP:

public function onEnable(){
      
        $this->tmn = "**Secret :P**";
        $this->omn = "**Secret :P**";
      
        $this->mapn = "Map: **** [1]";
        $this->gmid = "[1]";
      
        $this->leaderboard = new Config($this->getDataFolder() . "/leaderboard.yml", Config::YAML);
      
        $this->leaderboard->save();
        $this->leaderboard->reload();
      
        $this->getServer()->getPluginManager()->registerEvents($this, $this);

        $this->getLogger()->info("§l§c***** Loaded!");
      
        Server::getInstance()->loadLevel("*****Lobby");
        Server::getInstance()->loadLevel($this->omn);
        Server::getInstance()->loadLevel($this->tmn);
            
        $this->lobby = Server::getInstance()->getLevelByName("*****Lobby");
        $this->mapo = Server::getInstance()->getLevelByName($this->omn);
      
        $this->rn = 0;
      
        $this->inv = [];
        $this->armor = [];
      
        $this->spawns = [];
      
        $this->id = 1;
      
        $this->Spawn1 = new Vector3(610.5,29,-819.5);
        $this->Spawn2 = new Vector3(570.5,29,-819.5);
        $this->Spawn3 = new Vector3(569.5,29,-858.5);
        $this->Spawn4 = new Vector3(610.5,29,-859.5);
      
        $this->restartGame();
              
    }
  
    public function restartGame(){
      
        $this->P1 = 0;
      
        $this->id = 1;
      
        $this->RJ = [];
      
        $this->pid = [];
      
        $this->starting = 0;
              
        $this->winner = "";
      
        $this->Sign1 = $this->lobby->getTile(new Vector3(-10,6,151));
        $this->Sign2 = $this->Sign1; //$this->lobby->getTile(new Vector3(-11,6,151));
      
        $this->Sign1->setText("[Join]","SkyWars",$this->mapn,0 . "/4 Players");
        $this->Sign2->setText("[Join]","SkyWars",$this->mapn,0 . "/4 Players");
      
        $this->players = array();
      
        $this->started = 0;
      
        $this->deleteDir(Server::getInstance()->getDataPath() . "worlds/" . $this->tmn);
      
        $this->cpr(Server::getInstance()->getDataPath() . "worlds/" . $this->omn,Server::getInstance()->getDataPath() . "worlds/" . $this->tmn);

        $this->map = Server::getInstance()->getLevelByName($this->tmn);
      
        Server::getInstance()->unloadLevel($this->map);
      
        Server::getInstance()->loadLevel($this->tmn);
      
        $this->map = Server::getInstance()->getLevelByName($this->tmn);
      
    }



BUT, when i run it in a EntityLevelChangeEvent, i get that error.

Here is the code for that:

PHP:

    public function onWorldChange(EntityLevelChangeEvent $elce){
      
        //$this->getLogger()->info("§cPlayer Moved World");
      
        $wce = $elce->getEntity();
      
        if($wce instanceof Player && $this->P1 < 2){$this->restartGame();}
      
    }


For some reason, this works in a respawn event! (but i can't use that for my situation)

Thanks in advance! I hope i can get this fixed! (also, is it a pocketmine bug? )

What is the line 2039 in your code?

Nvm, its fixed. And that is in the pocket mine source code (2039)

Ah ok

You should enable debug mode and show us the stack trace.

its happening again. debug is enabled, where can i get the stack trace???
