SekCore Lib
by Sekwah
SekCore Lib is a shared library by Sekwah that supplies helper code to other Forge and NeoForge mods, including the author's own.
What it does
Sekwah wrote the library to speed up development of the author's mods, so it bundles common functions that several projects need. Its parts include capability synchronization through annotations, ragdoll physics, a color utility that offers a color wheel and the java.awt.Color mappings for Minecraft colors, and player utilities that simplify server-side calls. It also covers client-side velocity handling and fixes for a number of inconsistencies.
SekCore Lib is open source under the MIT License and runs on client and server, so both the server and every player need it. Files are published for Forge and NeoForge, with 7 release versions covering 1.18.2 – 1.20.1; the latest file for both loaders is 1.0.2 for 1.20.1, released on 2023-06-22. A Fabric port is planned, but no date is given.
Key features
Capability sync annotations
Annotations mark fields so that capability data is kept in sync between the server and clients.
Ragdoll physics
A ragdoll physics system is included for entities that need to collapse or tumble realistically.
Color utilities
A color wheel helper and mappings from java.awt.Color to Minecraft's colors make color handling simpler for mod code.
Player utilities
Helper methods simplify common player actions on the server side, reducing repeated boilerplate.

Use cases
Mod development
Developers who build on the library call its shared functions instead of writing the same helpers in each project.
Who it’s for: Mod developers who want shared helper code for Forge or NeoForge projects, and players who use mods that depend on this library.
How it compares
S-Lib is a Fabric, Forge and NeoForge library, open source under the MIT License, for 1.20.1 – 1.21.1, and it is client-side only, so servers do not need it. Sable: RagdollLib covers ragdoll physics on NeoForge for 1.21.1 under the GNU Lesser General Public License v3.0 or later and runs on client and server. Better Config is a Forge-only configuration option for 1.12.2, open source under the MIT License, with a client and server environment.
