Delete Floating text

I brought up a floating text with an order I created, but now I have no idea how I could delete it.

PHP:

<?php

namespace DevAkya\Commands\Staff\Admin;

use DevAkya\Main;

use pocketmine\level\particle\FloatingTextParticle;
use pocketmine\math\Vector3;
use pocketmine\level\Position;

use pocketmine\command\CommandSender;
use pocketmine\command\PluginCommand;
use pocketmine\Player;

use jojoe77777\FormAPI;
use jojoe77777\FormAPI\SimpleForm;

class FloatText extends PluginCommand {

     /** @var Main $plugin */
     private $plugin;

     const PREFIX = "§l§f[§l§4PRIVATE§f]§r ";
     const ADD = "§3Cliquer pour ajouter";

     public function __construct(Main $plugin) {
          parent::__construct("ft", $plugin);
          $this->setDescription("§4Floating Text");
          $this->setPermission("perm.admin");
          $this->plugin = $plugin;
     }

     public function execute(CommandSender $sender, string $commandLabel, array $args) {
          if($sender instanceof Player) {
               if($sender->hasPermission("perm.admin")) {
                    $api = $this->plugin->getServer()->getPluginManager()->getPlugin("FormAPI");

                    if($api === null || $api->isDisabled()) {
                         return true;
                    }

                    $form = $api->createSimpleForm(function(Player $sender, $data) {
                         $result = $data;

                         if($result === null) {
                              return;
                         }
                         switch($result) {
                              case 0: // Entity 1
                                   $n = $sender->getPlayer();
                                   $name = $n->getName();
                                   $money = "§61500ec";
                                   $online = $this->plugin->getServer()->getOnlinePlayers();

                                   $x = $sender->x;
                                   $y = $sender->y;
                                   $z = $sender->z;

                                   $title = "§7-=-=-=- §l§9Extoria§fNetwork§r §7-=-=-=";
                                   $text = "test";

                                   $fentityone = new FloatingTextParticle(new Vector3($x,$y,$z), $text, $title);
                                   $sender->getLevel()->addParticle($fentityone);
                              break;
                         }
                    });
                    $form->setTitle(self::PREFIX);
                    $form->setContent(self::PREFIX . "§cMerci de n'utiliser cette UI seulement si vous êtes l'utilisateur \n \n§7- §aAkyaSurMc \n \n ");
                    $form->addButton("§2Entity 1 \n " . self::ADD);
                    $form->sendToPlayer($sender);
               } else {
                    $sender->sendMessage("§cError ...");
               }
          } else {
               $this->plugin->getLogger()->info("Vous ne pouvez pas utiliser cette commande dans la console.");
          }
     }
}

 

I don't think it is possible to delete particle. It's better to make floating texts using entities. Here is my api which allows to remove texts too.

 

Can you explain to me from this API how a floating text spawn

 

PHP:

// Spawning text
$textId = FloatingTextApi::createText($vector3); // $vector3 -> position of floating text, This function is just for initialize
FloatingTextApi::sendText($textId, $player, "YourTextHere\nSecondLine"); // This you can use to spawn text, and for update too

// Removing text
FloatingTextApi::removeText($textId, $player); // It removes text just for the specified player..
