Solved Code doesn't seem to work

Hey! I am trying to make a plugin where obsidian breaks by TNT

PHP:

<?php

namespace minijaham\BreakableObsidian;

use pocketmine\block\Block;
use pocketmine\plugin\PluginBase;
use pocketmine\block\Liquid;
use pocketmine\entity\PrimedTNT;
use pocketmine\event\entity\EntityExplodeEvent;
use pocketmine\event\Listener;
use pocketmine\block\Obsidian;

class Main extends PluginBase implements Listener{
    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
    }
    public function onExplodeTnt(EntityExplodeEvent $event) {
echo '           Tnt Exploded BRUH            ';
        $blockList = $event->getBlockList();
        foreach($blockList as $key => $block) {
            if ($block->getId() === Block::OBSIDIAN) {
echo '           I found Obsidon Block BRUH            ';
                $level = $blockList[$key]->getLevel();
                $level->setBlock($blockList[$key], Block::get(Block::AIR));
            }
        }
    }
}

The code only returns:


Doesn't break the obsidian >:[

 

try

use pocketmine\block\Obsidian;
if ($block instanceof Obsidian)

and for your $level why get block via array, just use $block->getLevel()
var_dump can help you, this is a function who paste your variable in your console. Use on $block->getId() or $blockList, it can help you

 

I've tried
use pocketmine\block\Obsidian;
if ($block instanceof Obsidian)
which was my first code xD

And I'll use the $block->getLevel90

 

...

 

Wait no 90 was typo >:[

 

i know but you don't use $block but your array with your $key
