Error GetDataFolder ()

Hey, I have a problem When I run My code(bottom this message) Idea: I want to create a lang.yml for Player can change The language of Plugin.

PHP:

class loader extends command {
public function execute(CommandSender $args, $command, array $args){
$cfg= new Config($this->getDataFolder() . "lang.yml", Config::YAML);
$cfg->set("lang", "en");
$cfg->save();
#Some codes not important


Console return error getDataFolder ()
Sorry for my bad english

 

Are u sure you are using this at the top of your code?

PHP:

use pocketmine\utils\Config;

 

Your loader class shouldn't extend command, but PluginBase.

 

Lol, didn't even notice it...

 

What's the error exactly?
I think I knew it
Look, there is no getDataFolder method in \pocketmine\command\Command!
Hmm, let's see, where it is? it seems to be on \pocketmine\plugin\PluginBase...
let me check...
YES IT IS!
so pass the plugin object reference on the constructor, and replace it on $this->plugin.
then use $this->plugin->getDataFolder().

 

Example:

PHP:

//inside class...
public function __construct(\pocketmine\plugin\PluginBase $plugin, ...$args){
    parent::__construct(...$args);
    $this->plugin = $plugin;
}


so, you'll have to make the plugin reference as first argument in the Main class....

PHP:

$command = new LOLCOMMAND($this/*this is the plugin*/, /*whatever passed here...*/);

 

PHP:

use pocketmine\utils\Config;

yes i use it

So okay i test it but error

PHP:

Argument 2 passed to pocketmine\command\SimpleCommandMap::register() must be an instance of pocketmine\command\Command 

Thanks for all but i want lot of details i don't say it but i'm a little developper so i'm starting.
And Thanks for read that
But reply just if you can help me and be cool with me not be agressiv
sorry for my bad english i'm french

 

no
@Palente don't do that.

 

It really depends what you are trying to do.
Is the class you showed us your main class? Or is it just a seperate class for commands?

 

Wait, shouldn't it be like this?

PHP:

class something extends PluginBase implements Listener{

Correct me if I am wrong...

 

Depends. PluginBase is, as it says, the base class(you may just call it the main class(I don't mean the class name really, just an identifier)).
There you will have the onEnable(), onDisable, onCommand, etc. (If you need them) and this is the class you add to the plugin.yml, since this should get loaded. (it obviously has the startup stuff in onEnable())

You only need to implement the Listener in the class where you use events though.
Of course, you can do that in the Main class too, but that can get kinda messy.

Meh. This class is made to be a command, so it shouldn't be instanceof PluginBase in this case! Otherwise, he'd need to use onCommand. (Make sure to only have one Main class)

 

Thanks for review all.
This thread is now solved

Yes is it that they work thanks

 

Yeah you're right. I should have been clearer. I wasn't sure if he was trying to do that in his main file, as you usually call your main file Main, or Loader. You gave a way better reply though
