Gun Core
by Gamingbarn
Gun Core is a library that lets players build working guns with little setup and no coding knowledge.
What it does
The mod supplies the custom gun functionality that addons reference, so an addon can use firearm behavior without bundling the full feature set of the base pack. It is published for Fabric, Forge, NeoForge and Quilt, and also as a data pack for server platforms, across 12 release versions, 1.21.4 – 26.2.
The server must run the mod, but players may leave it out. Gun Core is released under a custom license and is not open source. Its listed public links are an issue tracker and a wiki. Required by 4 other mods, including Modern Guns, Chems' Guns, Pipe Guns and Zombies Guns, which depend on it for gun behavior.
Key features
Custom gun functionality
Guns can be assembled from the library without writing code, using its built-in gun mechanics.
Addon-ready library
Other datapacks and mods can reference the gun functions directly, without installing the base pack's extra features.
Updates applied to addons
Bug fixes in the library take effect for dependent datapacks and mods without those authors editing their own files.
Redistribution allowed
The license permits bundling, modifying and distributing the software inside a derived datapack or mod, and showing it in videos and streams.

Use cases
Gun addons
Authors of weapon packs build guns on top of the library instead of reproducing its functions.
Modded gun content
Mods such as Modern Guns and Chems' Guns use the library as the base for their firearms.
Who it’s for: Pack and addon authors who want firearm mechanics without writing them from scratch, and server owners who host the addons built on them.

What the author says
This is so that I and others can upload addons that reference the custom gun functionality from Gamingbarn's Guns, without needing to have all the supplemental features that come along in the base pack.
