Noob Question #2653: Reloading Worlds

Hi Guys

Title says all!

But because i feel like it, let me give you a story!

I got a skywars server, and i need to reload worlds. It keeps crashing with the infamous getChunk() on null error and the isChunkLoaded() on null error.

I had to modify the pocketmine source to fix this.

Anyway to reload in pocket mine properly? Also, the function is called in a EntityDamageEvent.

here is the whole reload function:

PHP:


public function restartGame(){

        $this->restarting = 1;
       
        $this->P1 = 0;

        $this->id = 1;

        $this->RJ = [];

        $this->pid = [];

        $this->starting = 0;

        $this->taken = [];

        $this->winner = "";

        $this->Sign1 = $this->lobby->getTile(new Vector3(-1329,66,-140));
        $this->Sign2 = $this->lobby->getTile(new Vector3(-1340,66,-135));

        $this->Sign1->setText("§a[Join]","§eSkyWars",$this->mapn,"§e0" . "/" . $this->maxp . " Players");
        $this->Sign2->setText("§a[Join]","§eSkyWars",$this->mapn,"§e0" . "/" . $this->maxp . " 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);  Crashes sometimes lolz

        foreach(Server::getInstance()->getLevels() as $gl){

            if($gl->getFolderName() == $this->tmn){

                $this->map = $gl;

            }

        }
       
        $this->restarting = 0;
       
        $this->reloadSigns();

       
    }




Avoid using Server::getInstance().

$this->getServer() ?

And do you think that's the cause?
