Set max players inside a plugin

Hi, I want to ask if it is possible to set the max players inside a plugin. Because I tried with setConfigInt and getConfigInt but it can only get the max players and can't set it. Please help.

PHP:

$cmd = preg_replace("/[^a-z]+/", "", strtolower($cmd->getName()));
        if ($cmd === "setmaxplayers" || $cmd === "maxjoin") {
            if (!isset($args[0])) {
                $this->getLogger()->notice("Debug: Original max players: " . $this->getServer()->getConfigInt("max-players"));
                return true;
            }
            $args[0] = intval($args[0]);
            if (!is_integer($args[0])) {
                return false;
            }
            $this->getServer()->setConfigInt("max-players", $args[0]);
            $this->getLogger()->notice("Debug: Max players have been set to: " . $args[0]);
            $sender->sendMessage(TF::GREEN . "Max players have been set to: " . $args[0]);
            $this->getServer()->doAutoSave();
            return true;
        }

 

PHP:

public $playerCount = 20;

public function onQuery(QueryRegenerateEvent $event) {
   $event->setMaxPlayerCount($this->playerCount);
}


 

Really thinks!
This is how I get more player slots on free pocketmine servers Lmao.

 

Nope. That just replaces displayed count. Server will still kick players if there were more than max player count specified in server.properties.

 

I wrote plugin for that 2 years ago. I'm not sure it still works, if it's even worked... But this function which cancells kicking player seems right.

 

oh ok

 

but actually ty for the function
