Tutorials/Programs and editors/Mod Coder Pack

The Minecraft Coder Pack is a collection of scripts and tools to help developers create mods for both the Minecraft server and client.

Description
We created a package that can help you to decompile, change and recompile the Minecraft classes. This should help mod creators to get started. Instructions included in the readme.txt file.The package contains scripts to decompile the game and the server.Version v2.0a can be found here:

In the past week our team has grown from 1 person (me) to over 10 people who are contributing to it. We have achieved a lot and put a lot of effort into this, so please don't skip the credits section in the readme.txt file :)

I want to thank everybody who has participated in making this release a reality and hope we can keep up the good work for the versions to come.

Important note: If you want to create mods for the unmodified minecraft.jar and minecraft_server.jar files, you have to wait for our next release. We have tools ready to support this, but there are some bugs left to sort out before we can release it. We are also working on another great tool for future Minecraft versions, but I don't want to spoil the surprise, so stay tuned.

There is also a spreadsheet that we use to generate de-obfuscation mappings.
