Flying

I am working on a plugin that lets people fly but whenever they click enable, it doesn't work.
Can someone tell me what I did wrong?

PHP:

    public function mainFrom($player){
        $plugin = $this->getServer()->getPluginManager();
        $formapi = $plugin->getPlugin("FormAPI");
        $form = $formapi->createSimpleForm(function (Player $event, array $args){
            $result = $args[0];
            $player = $event->getPlayer();
            if($result === null){
            }
            switch($result){
                case 0:
                    return;
                case 1:
                $sender->setFlying(true);
                    return;
                case 2:
                $sender->setFlying(false);
                    return;
            }
        });
        $form->setTitle(TF::BOLD . TF::BLACK . "FlyUI Menu");
        $form->setContent(TF::GRAY . "Enable/Disable Fly Mode!");
        $form->addButton(TF::GREEN . "Enable");
        $form->addButton(TF::RED . "Disable");
        $form->addButton(TF::WHITE . "Cancel");
        $form->sendToPlayer($player);
    }
 }

 

Because case 0 is set to button "enable" and case 0 there are nothing

 

Why are you trying Player::getPlayer()? The first argument was already an instance of Player...

 

I was going to add something, like economy but I changed my mind. And I changed it to case 0 and 1 and it still does not work.

 

Maybe do

PHP:

 var_dump($result); 

and check what the output is.

 

If you don't get any output, it means that another UI plugin might be conflicting with FormAPI.

 

Ahh ok, how do I use the one that is built into PMMP?
