namespace Miguu\Prueba;

use pocketmine\plugin\PluginBase;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\event\Listener;
use pocketmine\Player;

class Main extends PluginBase {

protected function onEnable() : void{
$this->getLogger()->info("Plugin has been Enabled");
$this->getServer()->getPluginManager()->registerEvents(new EventListener(), $this);
}
public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args) : bool{
switch($cmd->getName()){
case "lore":
$name = $sender->getName();
if($sender->hasPermission(prueba.command.lore)){
if(!$sender instanceof Player){
$sender->sendMessage("Gilipollas, esto solo funciona en el juego");
}
$sender->sendMessage("Lore," . $name . "te ama");
}
return false;
}
}
}
?>

 

Check the File name or check the plugin.yml if there is not a problem with folder name
