minecraft-jar-extractor

Extract structured data from the minecraft jar

image name extractor

Just run node image_names.js <version1,version2,...> <output_dir> <temporary_dir> and get a directory containing the name->texture mapping and the textures.

Result of that currently online at minecraft-assets

lang extractor

Just run node lang.js <version1,version2,...> <output_dir> <temporary_dir> and get a directory containing en_us.lang and en_us.json

protocol extractor

How to use it:

1. node downloadDecompile.js 1.8.8 /tmp/the_output
2. node protocol_extractor.js /tmp/the_output/decompiled
3. get a protocol.json describing the classname<->id relation and some fields information

block loot table extractor

Only works in 1.14+ as the loot table files did not exist before this.

Make sure to first extract the data folder from Minecraft jar if not done already using: node extract_datafolder.js <version1,version2,...> <output_dir> <temporary_dir>

Next you can extract the actual loot table data to Minecraft-Data using: node extract_lootTables.js <version1,version2,...> <extractedDataFolder> <mcDataFolder>

add defaultState to a blocks.json

1. node patch_states.js <version> blocks.json

add more accuracte drops to a blocks.json

1. node extract_datafolder.js <version> out temp
2. node extract_block_lootTables.js <directory with blocks.json and items.json> out/<version>/
