[New API] Saving/Loading Config

I'm trying to develop my first simple plugin. I've a big problem with reading configuration.
This is my code:

PHP:

namespace ChatTest;

use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\event\player\PlayerChatEvent;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerEvent;
use pocketmine\Player;
use pocketmine\IPlayer;
use pocketmine\utils\Config;

use pocketmine\utils\TextFormat;

class Test extends PluginBase implements Listener{
    public $config;
    public function onEnable(){
        @mkdir($this->getDataFolder());
        $this->getServer()->getPluginManager()->registerEvents(new Main($this), $this);
        $this->config = (new Config($this->getDataFolder()."config.yml", Config::YAML, array(
        "info" => "Join Player Test")))->getAll();
    }
  
    public function onPlayerJoin(PlayerJoinEvent $event){
        $this->config = $this->getConfig()->getAll();
        $event->setJoinMessage($this->TestInfo(). "test");
    }
    //Custom Functions
    public function TestInfo(){
  
        return $this->config["info"];
      
    }

  
}

When a player joins I get this error:
[NOTICE] An E_NOTICE error happened: "Undefined index: info-message" in "/ChatTest/src/ChatTest/Test"...

just use $this->getConfig() no need thefilename

The problem is "->getAll()"
You should use this:

Code:

$this->config = new Config($this->getDataFolder()."config.yml", Config::YAML, array("info" => "Join Player Test"));
$this->config = $this->config->getAll();

And remove this line:
"$this->config = $this->getConfig()->getAll();"

You don't need to get the config file every time a player joins. I'll fix it for when I get back to my computer.

Edit: Opps, forgot.

What about using the default config.yml resource?

PHP:

$this->saveDefaultConfig();
      
$this->config = $this->getConfig()->getAll();

Don't use $this->getConfig() if you decide to set $this->config yourself.

I think you have written some different code here because this should work, but the error says
"Undefined index: info-message" so you probably have to change that into"info"

Doesn't work. Can someone write the correct code?

PHP:

    public function onEnable(){
        @mkdir($this->getDataFolder());
        $this->saveDefaultConfig();
        $this->getServer()->getPluginManager()->registerEvents(new Main($this), $this);
        $this->config = $this->getConfig()->getAll();
        $this->getLogger()->info($this->TestInfo()); //<-Get Config "info" message
    }

In OnEnable() Event the logger gets the config message.
The problem is in OnPlayerJoin Event.

Please Help Me!

You need to make /resources folder in your plugin folder with /src and place the default config.yml file into there.

I did it

Can I load variables in OnEnable and share the value between functions?

Yes. Instead of storing as $varName, store as $this->varName (fields instead of variables). Look at https://github.com/PocketMine/PocketMine-MP/blob/master/src/pocketmine/plugin/PluginBase.php and look for private $...; lines. Do not use those names. (Therefore, do not use $this->config because it will break the PocketMine code that uses $this->config (as in $this->getConfig(), $this->reloadConfig() functions). Use another name, like $this->cfg)

PHP:

<?php

namespace _64FF00\ExamplePlugin;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerJoinEvent;

use pocketmine\plugin\PluginBase;

class ExamplePlugin extends PluginBase implements Listener
{   
    public function onEnable()
    {
        $this->saveDefaultConfig();
       
        $this->cfg = $this->getConfig()->getAll();
       
        $this->getLogger()->info('$this->cfg["TEST"] -> ' . $this->cfg["TEST"]);
    }
   
    public function onPlayerJoin(PlayerJoinEvent $event)
    {
        $event->setJoinMessage($this->cfg["TEST"]);
    }
}

Clever method, the underscore, to make 64FF00 a valid namespace :+1:

Thanks 64FF00 .
I solved the problem using __construct.
