Tutorials/Programs and editors/Mod Coder Pack

The Mod Coder Pack (Formerly Minecraft Coder Pack) is a collection of scripts and tools to help developers create mods for both the Minecraft (Java Edition) server and client.

Description
The package was created to help mod creators to decompile, change and recompile the Minecraft classes. Instructions are included in the readme files which come with the package. The package contains scripts to decompile, recompile, and reobfuscate the game and the server.
