    Hello, I'm working on better world generator for PocketMine. For better generator I need structures as village, igloos, etc. I've used NBT files from BDS to use default textures. NBT has 2 main list tags, palette and blocks. Pallete has format
    Code:
    [$index => (CompoundTag) [Name => "minecraft:blockname"], $index => ...]
    . I've tried to use ids from vanilla resources (block_id_map.json). However they were incomplete. How can I build same map with all the blocknames? Missing for example minecraft:dark_oak_log, minecraft:birch_planks or minecraft:dark_oak_planks

    PHP:
       private function load() {
            
    $data = (new BigEndianNBTStream())->readCompressed(file_get_contents($this->path));
            
    /** @var array $compound */
            
    $compounds $data->getValue();

            
    /**
             * @var int[] $palette
             *
             * stateId => pmmpId
             */
            
    $palette = [];

            
    /** @var CompoundTag $state */
            
    foreach ($compounds["palette"] as $state) {
                
    // $this->getBlockMap() returns pocketmine/resources/vanilla/block_id_map.json as array
                
    $palette[] = $this->getBlockMap()[$state->getString("Name")] ?? 0;
            }

            
    /** @var CompoundTag $blockData */
            
    foreach ($compounds["blocks"] as $blockData) {
                
    $pos $blockData->getListTag("pos");
                
    $state $blockData->getInt("state");
                
    $this->data[] = [$pos->offsetGet(0), $pos->offsetGet(1), $pos->offsetGet(2), $palette[$state]];
            }

            if(isset(
    $compounds["size"])) {
                
    /** @var ListTag $list */
                
    $list $compounds["size"];
                
    $this->axisVector = new Vector3($list->offsetGet(0), $list->offsetGet(1), $list->offsetGet(2));
            }
        }

    After first test I've got this result.
