About this Mod

This port is unofficial. The original buildcraft is licensed under MPL 2.0 just like this mod. No code/assets were reused.

A port of buildcraft to modern versions

About

This project, originally created for Modfest 2024, is an attempt at porting Buildcraft, step-by-step. This is why the mod only has a handful of features right now, but will be expanded gradually. The mod is not a 1:1 replica of the Buildcraft mod, but still very faithful. I decided to also include features from other old mods, that people used a lot with buildcraft like the Factorization Barrels.

The mod is still in its early stages and prone to bugs.

Roadmap

For anyone interested, here is a rough content roadmap:

  • Item Pipes, Crates, Tanks, Oil - Initial Release
  • Engines (Redstone, Stirling, Combustion, Creative) < Current
  • Pump/Quarry
  • Fluid Pipes
  • Lasers
  • Advanced filters
  • ...

Note that there is no ETA for any of these features, as I maintain and develop a lot of mods, which means the time I have to work on this, may vary strongly.

If you are interested in helping out, dont hesitate do submit a pr for a feature/bug-fix and join the Discord!

Frequently Asked Questions

Buildcraft-Legacy server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Buildcraft-Legacy compatible with neoforge?

Buildcraft-Legacy officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Buildcraft-Legacy – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Buildcraft-Legacy consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
