Knight Lib
A library that serves as a bridge between mods.
About this Mod

KnightLib is a multiloader utility library designed to eliminate code duplication and provide clean implementations of systems that every mod tends to reinvent from scratch.
● This library is fully compatible with Forge, NeoForge (1.21.1+), and Fabric, built on Jared's multiloader template.
● This mod includes a small amount of content that is disabled by default. Any mod wishing to use the content (items, blocks, icons, etc.) must first enable it in its implementation.
For any questions, problems, contributions, new ideas about content/mods, and more, you can join our official Discord and comment in the appropriate channels.

Knight Lib 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 (1.21.1). You can switch loaders with one click in the panel.
Is Knight Lib compatible with fabric and forge and neoforge?
Knight Lib officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Knight Lib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Knight Lib 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.
