MossyLib Mod Guide

What MossyLib Does

MossyLib is a shared library mod, not a content mod. It does not add blocks, items, or mobs on its own. Instead, it bundles the common code that LopyTwich's mods rely on, so each of those mods does not have to reimplement the same systems.

Why You Might Need It

If you install a LopyTwich mod and it fails to load or behaves oddly, a missing MossyLib is a common cause. Library mods like this are dependencies: the mods that use them will usually list MossyLib as required. Installing it alongside them resolves that dependency.

What It Provides

MossyLib includes a special YACL (Yet Another Config Lib) theme used across LopyTwich's mods, along with assorted utility code. It is also built to be multi-versioned and multi-loadered, meaning the same library supports different Minecraft versions and mod loaders.

Installation Notes

Treat MossyLib like any other library: place it in your mods folder next to the mods that depend on it, and make sure it matches your Minecraft version and loader. On its own it changes nothing visible in-game.
