sorry for my bad learne english

PHP:

class Main extends PluginBase implements Listener {
    
    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);   
        $this->getLogger()->info(TextFormat::GREEN . "CoreUI Enable");
    }
    public function onDisable() {
        $this->getLogger()->info(TextFormat::RED . "CoreUI Disable");
    }
    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args) : bool {
        switch($cmd->getName()){                   
            case "coreui":
                if ($sender->hasPermission("coreui.command")){
                     $this->Menu($sender);
                }else{     
                     $sender->sendMessage(TextFormat::RED . "You dont have permission!");
                     return true;
                }     
            break;         
            
         } 
        return true;                         
    }
  
    public function Menu($sender){
        $api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
        $form = $api->createSimpleForm(function (Player $sender, int $data = null) {
            $result = $data;
            if($result === null){
                return true;
            }             
            switch($result){
                case 0:
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "Enabled flight mode!");
            $sender->setAllowFlight(true);
                break;
                case 1:
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "Disabled flight mode!");
            $sender->setAllowFlight(false);
                break;               
                case 2:
            $sender->setHealth(20);
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "Your has ben Healed");
                break; 
                case 3:
            $sender->setFood(20);
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "You have been feed!");
                break; 
                case 4:
            $sender->setGameMode(1);
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "GameMode changed to §9Creative");
                break;
                case 5:
            $sender->setGameMode(2);
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "GameMode changed to §9Adventure");
                break;
                case 6:
            $sender->setGameMode(3);
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "GameMode changed to §9Spectator");
                break;           
        case 7:
            $sender->addEffect(new EffectInstance(Effect::getEffect(Effect::INVISIBILITY), 99999999, 0, false));
            $sender->addTitle(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "Vanish Enabled");
                break;           
        case 8:
            $sender->removeEffect(Effect::INVISIBILITY);
            $sender->addTitle(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "Vanish Disabled");
        break;       
        case 9:
            $command = "pl" ;
            $this->getServer()->getCommandMap()->dispatch($sender, $command);
        break;         
                case 10:
            $sender->sendMessage(TextFormat::LIGHT_PURPLE."(CORE) ". TextFormat::YELLOW . "CoreUI Closed");
                break;               
            }
            
            
            });
                $form->setTitle(TextFormat::BOLD. TextFormat::LIGHT_PURPLE."CORE");
        $form->setContent(TextFormat::GRAY."Author: DaRealAqua\n".TextFormat::GRAY."Version: 0.0.2");
                $form->addButton(TextFormat::GRAY."Enable Fly\n".TextFormat::LIGHT_PURPLE."Tap for Activate Fly");
        $form->addButton(TextFormat::GRAY."Dezactive Fly\n".TextFormat::LIGHT_PURPLE."Tap for Disable Fly");
        $form->addButton(TextFormat::GRAY."Heal\n".TextFormat::LIGHT_PURPLE."Tap for Heal");
        $form->addButton(TextFormat::GRAY."Feed\n".TextFormat::LIGHT_PURPLE."Tap for Eat");
        $form->addButton(TextFormat::GRAY."Creative\n".TextFormat::LIGHT_PURPLE."Tap to change GM");
        $form->addButton(TextFormat::GRAY."Adventure\n".TextFormat::LIGHT_PURPLE."Tap to change GM");
        $form->addButton(TextFormat::GRAY."Spectator\n".TextFormat::LIGHT_PURPLE."Tap to change GM");
             $form->addButton(TextFormat::GRAY."Vanish on\n".TextFormat::LIGHT_PURPLE."Press for Activate Vanish");
            $form->addButton(TextFormat::GRAY."Vanish off\n".TextFormat::LIGHT_PURPLE."Press for Disable Vanish");
            $form->addButton(TextFormat::GRAY."Plugins\n".TextFormat::LIGHT_PURPLE."Show Server plugins");   
                $form->addButton(TextFormat::RED."Close");
                $form->sendToPlayer($sender);
            return $form;                                           
    }
 
                                                                                                                                                                                                                                                                                          
}

 

Change your button definitions to something like this. I've done the first one for you:

PHP:

$form->addButton(($sender->hasPermission("your.permission") ? TextFormat::GREEN : TextFormat::RED) . "Enable Fly\nTap for Activate Fly");

This is the ternary operator in PHP, and it works a lot like an "if/else" statement. If the first operand is true, evaluate as the second, otherwise evaluate as the last.
