getTiles() error

Guys how to fix this kind of error?

Code:

[11:27:32] [Server thread/CRITICAL]: Error: "Call to a member function getTiles() on null" (EXCEPTION) in "MicroBattle v1.1.0 PRO.phar/src/LittleBigMC/MicroBattles/MicroBattles" at line 633

Here is line 633

PHP:

public function onRun($tick)
    {
        $allplayers = $this->plugin->getServer()->getOnlinePlayers();
        $level = $this->plugin->getServer()->getLevelByName("MBLobby");
        $tiles = $level->getTiles(); //Line 633
        foreach($tiles as $t) {
            if($t instanceof Sign) {   
                $text = $t->getText();
                if($text[3]==$this->prefix)
                {

 

Change

PHP:

$tiles = $level->getTiles();


to

PHP:

$tiles = $level->getTiles($allplayers);

it error because it didnt has anything to getTiles

 

While it's easy to think that, the issue is actually that $level is returning null. $level->getTiles doesn't require any parameters.

Either MBLobby doesn't exist, or it isn't loaded when this code is being executed. You can't get tiles from a level that isn't loaded.
