$spawner->getCustomBlockData() returns null

 

alright

 

Try this for add tag.

PHP:

$spawner = Item::get(Item::MOB_SPAWNER, 0, 1);
$customBlockData = new CompoundTag("");
$customBlockData->setInt("EntityId", $tile->getEntityId());
$spawner->setCustomBlockData($customBlockData);
$spawner->setCustomName($this->getSpawnerName($spawner));

After use this for get entity ids.

PHP:

   /**
   * @var Item $spawner
   * @return null|string
   */

public function getSpawnerName(Item $spawner) ?string {
   $nbt = $spawner->getCustomBlockData();
   if ($nbt->hasTag("EntityId", IntTag::class)) {
     $entityId = $nbt->getInt("EntityId");
     switch ($entityId) {
       // Code

     }

   }

 }

 

it's working but the issue is the name is not setting and once u place the spawner again and mine it, nothing drops
