EasyForm Help

Hi, here is my code

PHP:

<?php

declare(strict_types=1);

namespace MrDinoDuck\AdvancedWings;

use pocketmine\plugin\PluginBase;
use pocketmine\command\CommandSender;
use pocketmine\command\Command;
use pocketmine\Player;
use jojoe77777\FormAPI\{CustomForm, SimpleForm};
use MrDinoDuck\AdvancedWings\Forms\WingMenu;
use MrDinoDuck\AdvancedWings\Tasks\ParticlesTask;
use MrDinoDuck\AdvancedWings\Forms\{WingUI, CircleUI, WalkingUI};
use Frago9876543210\EasyForms\elements\Button;
use Frago9876543210\EasyForms\forms\MenuForm;

class Main extends PluginBase{
   
    public $wing = [];
    public $circle = [];
    public $walking = [];

    public function onCommand(CommandSender $sender, Command $command, string $label, array $args) : bool{
        switch($command->getName()){
            case "wings":
            $sender->sendForm(new MenuForm("§a[§b§lWings§r§a]", "§9•§e Chọn loại hình", [
    new Button("Wing"),
    new Button("Circle"),
    new Button("Walking")]),
    function(Player $player, Button $selected) : void{
        if($response->getText() === "Wing"){
            $wing = new WingUI($this);
            $player->sendForm($wing);
        }elseif($response->getText() === "Circle"){
            $circle = new CircleUI($this);
            $player->sendForm($circle);
        }elseif($response->getText() === "Walking"){
            $walking = new WalkingUI($this);
            $player->sendForm($walking);
        }
    }
);
        return true;
    }
}
}


When i clicked on the button, it do nothing. No Console Error. Please help

 

Here's a trick to debug such errors.
Print the value in the console.

PHP:

var_dump($response->getText());


Does it meet any of your if cases? Or if nothing gets outputted in the console, then consider that part of the code is not executing.

 

Are you sure there were no errors? It seems to me that $response is not defined

 

i changed that but it still didnt do anythings

 

I need a code UI button that can connect with other UI commands
