Do I need OwO Lib to play Minecraft?

No. OwO Lib is a library mod, meaning you only need it if another mod lists it as a dependency. Install it in your mods folder alongside that mod and it runs in the background without you needing to touch anything.

Does OwO Lib work with Forge?

No, it's Fabric-only. You need Fabric Modloader and Fabric API installed for it to work. Quilt is also supported on 1.19 and above.

What does OwO Lib actually do when I'm playing?

Nothing you'll notice directly. It gives other mods access to its tools, like better particles and registration systems, and runs quietly in the background. OwO Lib itself doesn't add items, blocks, or menus to your game.

Will OwO Lib cause any mod conflicts?

It's unlikely. Since it's a library that doesn't touch gameplay directly, conflicts are rare. The usual rule applies though: make sure every mod in your pack matches your Minecraft version.

Do I need to configure OwO Lib after installing?

No configuration needed. Drop the .jar into your mods folder alongside Fabric API and it just works.

OwO Lib Mod (1.19.4, 1.18.2) - Fabric Utility Library

OwO Lib is a utility library for Fabric mods. It handles the plumbing that mod developers need, like automatic registration, a cleaner particle API, and tabbed item groups, so they don’t have to write it from scratch. If a mod you want to use requires OwO Lib, just drop it in your mods folder alongside it.

What OwO Lib Provides

Automatic Registry System

A generic registry system that works for standard Minecraft registries and any custom storage system you want to hook in. You declare values in class fields and the library takes care of registration. Not verbose, not complicated.

Tabbed Item Groups

Instead of splitting a big mod across three separate creative tabs, OwO Lib supports sub-tabs inside a single item group. Keeps your inventory clean and your mod organized.

RegistryHelper

Specify one or more registry entries, and RegistryHelper runs your code when those entries show up. This makes inter-mod compatibility fast to add without a ton of boilerplate.

Better Particle System

Vanilla’s particle API is genuinely unpleasant to work with. OwO Lib wraps it so you can spawn particles with random distributions or precise geometric arrangements without fighting the engine. It also makes server-side particle triggers straightforward, no extra packet setup needed.

ItemStack Utilities

Common comparison and verification operations for ItemStacks are included. Nothing flashy, just removes repetitive code when checking or handling items.
