SetBlock área

Hi, I wanted to know what's wrong. I want to clean a 7x7 area of blocks, but it's not clean. how I achieve it. this is my code!

Code:

public function setReset(string $arena, $update = false) {
            $config = new Config($this->plugin->getDataFolder() . "/config.yml", Config::YAML);
            $levelArena = $this->plugin->getServer()->getLevelByName($arena);
            $lg = $config->get($arena."lobby");
            if($levelArena instanceof Level) {
                for($spawn=1; $spawn<=8; $spawn++) {
                    $spawners = $config->get($arena."Spawn".$spawn);
                    for($piso=1; $piso<=7; $piso++) {
            $levelArena->setBlock(new Vector3($spawners[0]-3,$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0]-2,$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0]-1,$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0],$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0]+1,$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0]+2,$spawners[1]+$spawn,$spawners[2]-4+$piso), Block::get(0),$update,$update);
            $levelArena->setBlock(new Vector3($spawners[0]+3,$spawners[1],$spawners[2]-4+$piso), Block::get(0),$update,$update);
            }
      }
}

 

you must set the 3rd parameter (update) to true

 

It did not work: 'v

 

do var_dump($spawners); and see if that's the area you're standing in

 

Is your level loaded?
Did you use pocketmine/level/Level?
By not clean, do you mean some blocks remain or all blocks are left untouched?
