minecraft-jar-extractor

python tools for extracting data from minecraft .jars

Usage

protocol_extractor.py

 $ python protocol_extractor.py decompiled_files_dir/

decompiled_files_dir should contain the decompiled source of a minecraft.jar. During testing, I used fernflower from https://the.bytecode.club/showthread.php?tid=5 with:

 $ java -jar fernflower.jar minecraft.jar decompiled_files_dir

after that, extract decompiled_files_dir/minecraft.jar into decompiled_files_dir.

Comparison to PrismarineJS's NodeJS protocol_extractor.js

• sample output (left side is js, right is this repo)
• this extractor is a python 3.4 port of that, with tiny changes
• that extractor was made with a different version of fernflower possibly
