CoroUtil

by Corosus

CoroUtil is a shared code library that Corosus's own mods depend on, bundling the common code of several earlier Forge mods into one package.

FabricForgeNeoForgeClient and serverAll rights reserved1.16.5 – 1.21.4

What it does

Nine other mods list CoroUtil as a requirement, among them What Are They Up To (Watut), Zombie Awareness, Weather Storms & Tornadoes, Mobtimizations - Entity Performance Fixes and Weather2 Additions. Installing one of those mods without CoroUtil leaves them unable to start.

The library combines the code formerly split across the coroai, buildmod, configmod and extendedrenderer mods. It is published across 11 release versions, under All rights reserved, and it is not open source. Client and server both need the library.

Key features

  1. Shared code for Corosus mods

    Common routines used across the author's mods live in one package, so each mod does not carry its own copy.

  2. Routines for dependent mods

    Utility functions for building, configuration and rendering are kept in the library, so dependent mods call a single shared copy.

  3. Latest release builds

    The newest Fabric and NeoForge files are 1.21.4-1.3.8 for 1.21.4, dated 2025-03-20, and the newest Forge file is 1.21.0-1.3.7 for 1.21.1.

Questions

Does CoroUtil need to be installed for other mods to work?

Yes. Nine catalog mods, including Watut and Zombie Awareness, require it, so it must be installed alongside any of them.

Is CoroUtil needed on the server as well as the client?

Both sides run it: the server and each player need the library in their mods folder, since the mod is client and server.

In the catalog

CoroUtil is one of 3,514 Library mods on ModsFinder, and one of 2,348 Library mods for Fabric. 17,979 mods support Minecraft 1.21.4.
