Quantics Core
by TerviXx
Quantics Core is a Fabric library that Quantics mods share for their configuration screen, GUI components and module registration.
What it does
Quantics Core supplies the common systems that other Quantics mods build on. It provides a unified configuration screen, shared GUI components, a module registration system and a set of reusable utilities, so every Quantics project presents settings and interface elements in the same way. Installing the library on its own also adds gameplay features, and the mods that depend on it draw on the same shared code.
The library is client-side only, so only the client needs it and a server can run without it. It requires Cloth Config API and Fabric API, which must be installed alongside it. Files are published for Fabric, covering game versions 1.21.4 – 1.21.8, with 1.0.2 for 1.21.8 as the latest file on the beta channel. The mod is released under All rights reserved and is not open source.
Key features
Unified configuration screen
A single configuration screen is shared by Quantics mods, so settings look and behave the same across the ecosystem.
Shared GUI components
Common interface widgets are provided for dependent mods to reuse instead of building their own.
Common module registration
A shared registration system lets Quantics mods register their content through one common path.
Reusable utilities
Helper code used across the Quantics projects is collected in the library, reducing duplicated work in each mod.

Use cases
Running Quantics Elytra Swap
Quantics Elytra Swap requires this library, so the library must be installed for that mod to load.
Adding future Quantics projects
New Quantics mods can rely on the same configuration and GUI systems instead of implementing them separately.
Who it’s for: Players who use Quantics mods and mod developers building add-ons for the Quantics ecosystem. Players who only want the library's own features should install it alongside the Fabric API and Cloth Config API.
