Setting blocks with async task

Howdy! I've been trying to place blocks through an async task and have had no success, I've always had it crash with "setBlockIdAt" on null.

Code for placing blocks:

PHP:

$store = $this->getFromThreadStore("generator.level{$this->levelId}.manager");
for($minX = -$this->border; $minX <= $this->border; $minX++){
      for($y = 50; $y <= 100; $y++){
          $store->setBlockIdAt($minX, $y, $this->border, Block::BEDROCK);
      }
}

Code for calling the task:

PHP:

$level = $this->plugin->getServer()->getDefaultLevel();
$this->plugin->getServer()->getAsyncPool()->submitTask(new PlaceBlockTask($border, $level->getId()));

 

you can serialize the chunks you want to change, then deserialize it in the task, then you can loop the chunks to your suit

PHP:

/** @var Chunk $chunk */
$serializedChunk = $chunk->fastSerialize();
/** of course you can make this an array and loop it in the task to change more chunks
$this->plugin->getServer()->getAsyncPool()->submitTask(new PlaceBlockTask($border, $serializedChunk));


then in the task you can do

PHP:

$chunk = Chunk::fastDeserialize($this->serializedChunk);
/** There are only 16x16x256 blocks in a chunk */
for($xx = 0; $xx < 16; $xx++){
    for($zz = 0; $zz < 16; $zz++){
        for($yy = 50; $y <= 100; $yy++){
            //$chunk->setBlock(); blah blah..
        }
    }
}


 

Doesn't appear to be placing anything.

 

You need to serialize the chunk again after you are done setting the blocks in onRun, then $this->setResult($serializedChunk);
Then onCompletion you unserialize the chunk(getResult) and setChunk on your level

 

Why not unserialize in the async task?
