Flintcore
by Livelandr
Flintcore is a Forge library of weapon core code for building guns, ammunition and attachments that interact across mods through tags.
What it does
Flintcore provides a basic weapon core: a shared foundation that other mod authors can build guns, ammunition and attachments on. Items can interact across different mods by using tags, so a gun from one mod can accept an attachment from another without direct code links. The core was split from the Flint'N'Powder project as a separate library, and the source code is public. Installation covers the server and each player's game. It is released under the GNU Lesser General Public License v3.0 or later, and is open source. Files are published for Forge 1.20.1 only, with version 1.2 as the latest file.
