About this Mod
libnine is a library that provides a bunch of boilerplate code for content mods to use. It mostly consists of various bits of code that I found useful in more than one project, which I then factored out into a shared library. Particularly notable features include:
- Automatic generation of NBT and byte stream serializers based on annotated fields
- Various prefab capability implementations
- A generic recipe registry system
- "Parametric item models" that can depend on nontrivial item stack state
- A GUI component system and corresponding sync code
- A huge pile of linear algebra nonsense
However, a lot of the code in this project is rather dated and the architecture is a little bit questionable. As such, I would not recommend depending on libnine for new modding projects.

libnine server crashes on startup – what to do?
Most common cause: wrong forge 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 (1.12.2). You can switch loaders with one click in the panel.

libnine officially supports forge for Minecraft 1.12.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with libnine – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if libnine 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.
