Command not working.

When the command /kitpvp is executed, the only feedback I get is "Usage: /kitpvp"

PHP:

<?php

namespace RumDaDuMCPE;

use pocketmine\command\{CommandSender, Command};

class Main extends \pocketmine\plugin\PluginBase {

public function execute(CommandSender $player, Command $cmd, array $args, $label) {
switch ($cmd->getName()) {
case "kitpvp":
$player->addTitle("§l§6RumBenCraft", "§a>> §l§eConnecting to Kit-PvP §r§a<<", 5, 80, 20);$packet = new \pocketmine\network\mcpe\protocol\TransferPacket();
$packet->address = "here.there.what";
$packet->port = 10;
$player->dataPacket($packet);
return true;
}
}
}

Solved.

PHP:

<?php

namespace RumDaDuMCPE;

use pocketmine\command\{CommandSender, Command};

class Main extends \pocketmine\plugin\PluginBase {

public function execute(CommandSender $sender, Command $command, $label, array $args) {
switch ($command->getName()) {
case "kitpvp":
$sender->addTitle("§l§6RumBenCraft", "§a>> §l§eConnecting to Kit-PvP §r§a<<", 5, 80, 20);$packet = new \pocketmine\network\mcpe\protocol\TransferPacket();
$packet->address = "here.there.whatt";
$packet->port = 10;
$sender->dataPacket($packet);
return true;
}
}
}
