About this Mod

This project is still in development!

Description

Shuttle is a lightweight open-source addon library for adding extension support to your mods. It allows for dynamic registration of objects which can be pulled and used within your mod easily, as well as allowing provision of instances which might be required for the construction of certain objects.

Should I use it?

You can and / or should use this library if:

You are creating a public addon api for your mod
You want to easily extend your own mod (with more mods :p)
You want to, for some othe reason, provide the ability to register new stuff in or internally tweak with your mod(s)

Why?

After rewriting the addon system for Cactus Mod I decided to publish it as an open-source library for other modders to use.

For now, there isn't really documentation on it - I'm maintaining this in my free time and will create some docs when I have time for it.

Frequently Asked Questions

Shuttle server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.8). You can switch loaders with one click in the panel.

Is Shuttle compatible with fabric?

Shuttle officially supports fabric for Minecraft 1.21.8, 1.21.7, 1.21.6. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Shuttle – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Shuttle 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.
