Description
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, is forced to enable it in its implementation. So, in other words, this mod does nothing on its own, unless an external mod specifies so.
For any questions, problems, contributions, new ideas about content/mods, and more, you can join our official Discord and comment in the appropriate channels.
