Called to an undefined method

Hello I’m making a plugin and everytime I run this command I get this error “Called to an undefined method Tb\Tb::isMapsOnline()”
This line where it crashes

PHP:

 }  else if ($args[0] === "join") {
  $this->isMapsOnline($player);    

This Is the isMapsOnline method

PHP:

public function isMapsOnline(Player $player) : void {
           $config = new Config($this->getDataFolder()."/config.yml", Config::YAML);
        if($config->get("arenas")!=null) {
            $maps = $config->get("arenas",[]);
             foreach($maps as $online) {
                  $rule = $config->get($online."Game");
                     if($rule==Settings::PRE_TO_START_1) {
                       if($this->isArenaUse($online)==true) continue;
                         $this->joinMH($pl,$online);
                         break;
                      } else {
                    $player->sendTip("§f[SK]§6 Finding you a match!");
                       }
                   }
                } else {
                    $player->sendMessage("§c[ERROR]§6 Maps are full!");
                    }
           }

Make sure they aren’t in a different file.

 

Is this function in the same class?

 

No, and I think that is the error but I’m not sure how to call the method

 

Yes that's it
