Curios API Continuation
by SSKirillSS
With Curios API Continuation, developers can add extra accessory and equipment slots to NeoForge mods, and players can configure those slots.
What it does
The library provides a shared system for extra accessory and equipment slots. Developers register slots through its interface so their items fit into a common, compatible structure, and players can adjust which slots exist and how they are arranged to suit their preferences. Curios API Continuation is a continuation of the original Curios project, and it runs on client and server, so both the server and every player need it.
By default the mod adds no content of its own beyond an inventory screen that displays the slots. No slots are defined out of the box, and only two example items exist, which appear in the Creative menu and serve as references for developers writing their own integration. Curios API Continuation is released under the GNU General Public License v3.0 or later and is open source. Files exist for NeoForge, with the 1.21 and 1.21.1 game versions covered and 9.0.15+1.21.1 as the latest file for 1.21.1, published 2024-11-09. Jahdoo requires it.

How it compares
Curios Backpacks is a NeoForge mod for 1.21.1 that is not open source and is licensed under the MIT License. AccessoryLib is also for NeoForge 1.21.1, is open source and is licensed under the MIT License, so it covers a similar accessory role. Refined Storage - Curios Integration is open source under the MIT License and covers 1.21.1 – 26.1.2 on NeoForge, and it is a bridge to storage rather than a slot framework.
