Here are many utility classes used for updating protocols and exporting data. All generated files are typically located in the build or resource directory.

1. we first need to update the protocol library, which simply requires copying and pasting from Cloudbrust to PNX.
2. Then we need to update https://github.com/CloudburstMC/BlockStateUpdater to PNX's cn\nukkit\level\updater\block
3. update https://github.com/df-mc/worldupgrader/tree/master/itemupgrader/schemas to PNX's cn\nukkit\level\updater\item
4. update resource use DownloadResource.java and other,For recipes, you need to use either https://github.com/AllayMC/Allay/blob/master/Allay-Data/src/main/java/org/allaymc/data/RecipeExportUtil.java or https://github.com/JukeboxMC/data-extractor.
5. Remove deprecated block states and block property from the PNX code and rename block classes if there are changes in block names. this is a breaking change that occurs almost every version until Minecraft's bedrock version no longer modifies block states.
6. The api related to the addon may also change. If there are errors, you need to load the addon in the vanilla BDS and observe the corresponding packets sent through proxypass. These packets are usually ItemComponentPacket for custom item, StartGamePacket#blockProperties for custom block , and AvailableEntityIdentifiersPacket for custom entity.

The language files related to commands used for exporting PNX from BDS.
After the export is completed, you still need to manually copy the language files into the PNX.

Download BDS from https://www.minecraft.net/en-us/download/server/bedrock ,update the path to your BDS folder

cn/powernukkitx/codegen/BdsLangExport.java:21
static final String TARGET = "C:\\Users\\admin\\Downloads\\bedrock-server-1.20.51.01\\resource_packs\\vanilla\\texts";

then run main method

Download the biome files from AllayMC and generate the corresponding BiomeID.class for PNX. This file does not need to be updated frequently because biomes are not updated often.

Run main method

Download the block_attributes files from AllayMC and generate the corresponding block_color.json for PNX. The block_attributes from AllayMC may not be updated promptly, as this depends on LeviLamina's update speed. However, it's not critical because this file is not the most important; it only affects the color filling of the map and doesn't need to be updated as frequently.

Run main method

generate the corresponding BlockID.class and new Block class for PNX.
you must be run it after DownloadResource.java.

Run main method

unzip the block_attributes.nbt

Run main method

Convert the string exported from the protocol typeMap into constants in PNX format.

Change the string. then run main method

Updating the necessary resources requires waiting for CloudBurst/Data to update, but they usually update very quickly.

Run main method

generate the corresponding EntityID.class for PNX.
you must be run it after DownloadResource.java.

Run main method

generate the corresponding ItemID.class and some new Item class for PNX.
you must be run it after DownloadResource.java.

Run main method

Select class files that match the pattern from the batch-generated block classes

Run main method

Used to export the block_property_types.json file. This file is a requisite for run BlockIDGen.

Use DownloadResouce to update block_palette.nbt Run main method

refer https://github.com/CoolLoong/data-extractor

Dump the block palette to a txt

Run main method
