Plugin Error

When i break a Block then comes this Error:

Code:

[Server] Warning: in_array() expects parameter 2 to be array, string given in /storage/emulated/0/PocketMine/plugins/Protector/src/Protector/Main.php on line 32

Here is my Code:

PHP:

<?php

namespace Protector;

use pocketmine\event\Listener;
use pocketmine\plugin\PluginBase;
use pocketmine\event\block\BlockBreakEvent;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\utils\Config;
use pocketmine\utils\TextFormat as C;

class Main extends PluginBase implements Listener {
    
    public $prefix = C::GRAY. "[". C::RED. "ProtectionManager". C::GRAY. "]". C::WHITE;
    public $welten = [];
    
    public function onEnable() {
        $this->getLogger()->info($this->prefix. "Lade Plugin");
        @mkdir($this->getDataFolder());
        $cfg = new Config($this->getDataFolder(). "Config.yml", Config::YAML);
        if(empty($cfg->get("NoBlockBreak"))){
            $cfg->set("NoBlockBreak", "lobby");
        }
        $this->welten = $cfg->get("NoBlockBreak");
        $cfg->save();
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->getLogger()->info($this->prefix. "Plugin geladen");
    }
    
    public function onBreak(BlockBreakEvent $event) {
        if(in_array($event->getBlock()->getLevel()->getName(), $this->welten)) {
            $event->setCancelled();
            $player->sendMessage($this->prefix. " Du darfst in der Lobby nichts Abbauen");
        }
    }
}

 

Make sure $this->welten is an array, it seems to be a string currently.
Can you also show us your config file?

 

This is workaround, not a fix!

PHP:

if(in_array($event->getBlock()->getLevel()->getName(), $this->welten)) {


to

PHP:

if(in_array($event->getBlock()->getLevel()->getName(), [$this->welten], true)) {


 

This is in the Config

Code:

---
NoBlockBreak: lobby
...

 

Your config needs to look like this:

Code:

---
NoBlockBreak:
 - lobby
...

 

How can i make this so? I ve been trying to tap Tap and it will change this to this:

Code:

---
NoBlockBreak:
- lobby
...

 

Try doing this

PHP:

$cfg->set("NoBlockBreak", ["lobby"]);

 

Um, (array) casting will be better since it'll convert "string" to ["string"].

 

So?

PHP:

if(in_array($event->getBlock()->getLevel()->getName(), ["$this->welten"], true)) {

 

PHP:

if(in_array($event->getBlock()->getLevel()->getName(), (array) $this->welten)) {


 

Only if $this->welten is always a string.

 

I just realised it. I thought that you were commenting on array casting, rather than my "[]" code.

 

Just make sure NoBlockBreak is an array in your config
if you need help handling arrays in the config, there are alot of threads that have been solved about this question.

 

How can i make a handling array in a config?
