How to cancel PlayerGameModeChangeEvent?

Hi, I'm having trouble hooking into PlayerGameModeChangeEvent to cancel it, but can't find any API 2.0.0 examples of how to use it. The source code says that it returns a player object and gamemode int, and no event - which is what I'm trying to cancel :-/

I've tried this (adapted from some code I found), and variations with only the 2 arguments for player/newgamemode, and using $player instead of $c->getPlayer... but it doesn't get called whatever I try, even though all other listeners are working fine.

PHP:

public function onGameModeChange(PlayerKickEvent $k, Player $player, PlayerGameModeChangeEvent $c, Permission $permission, NewGameMode $newGamemode) {
            if (isset($this->sessions[$c->$player->getName()])) {
            $c->setCancelled(true);
            $c->getPlayer->setGamemode(0);
            $c->getPlayer->sendMessage($this->getMessage("no-cheat"));
            }
        }

Thanks

Why set a player's gamemode if you cancel the event?

PHP:

use pocketmine\event\player\PlayerGameModeChangeEvent;

    public function onPlayerGameModeChangeEvent(PlayerGameModeChangeEvent $event){
        $event->setCancelled(true);
        $event->getPlayer()->sendMessage("no-no!");
    }



however, this code will cancell ALL gamemode changes. even from the console. You have to add more checks in the code

Thank you very much, I'll try that now.

@MCPEPIG I'm writing a parkour plugin, and need to prevent players from switching gamemode (or having a friend change gamemode for them etc)

Nice and simple after all... that's perfect, thank you!

Goog luck in plugins writing!

It all seems like a great idea. Good luck with that.

Just pointing put ( just in case anyone is unaware )
Within the SERVER.PROPERTIES there is a part saying

Code:

force-gamemode=

Make that "on" for it to PUBLICALLY force the gamemode to what ever you set
the

Code:

gamemode= (0/1/2/3)

to.

Just a helpful hint just incase thats what anyone needs
