Railcraft - A Minecraft Mod

Here you will find the source and issue tracker for the Official Railcraft Project.

What is Railcraft?

Railcraft is a mod written for the hit game Minecraft. It is built on top of the Minecraft Forge API.

It greatly expands and improves the Minecart system in Minecraft. Adding many new blocks, entities, and features. It has been in development since 2012 and contains over 800 class files and hundreds of thousands of lines of code.

The mod was created and is still currently maintained by the user going by the name CovertJaguar.

Why are you posting the Source Code?

In the words of CovertJaguar:

As a new modder, I originally feared losing control of my code, my brainchild. However, since that time, I have had the privelege of being Project Lead on two other major Minecraft Mod projects that provided access to the source: Buildcraft and Forestry. I've generally found this to be a positive experience resulting in many bug fixes and increased intermod compatibility. While I still have some concerns, I have come to feel that the benefits of providing others access to my source code outweigh the negatives and unknowns. To that end, despite my misgivings, I made Source Access a Patreon Milestone Goal. I had no idea whether I'd ever meet that Goal, but I decided to let the community decide, and decide they did, overwhelmingly so! My Patrons are awesome. So, as promised, I am posting the Source Code.
