Sophisticated Fabric Lib
by Salandora
Sophisticated Fabric Lib is a shared library on Fabric that supplies the systems Unofficial Fabric Ports of Sophisticated mods rely on.
What it does
The library handles inventory item movement, fluid and energy transfer, client-server synchronization, game event and loot hooks, and rendering support for Sophisticated items, screens and particles. Unofficial Fabric Ports such as Sophisticated Backpacks and Sophisticated Storage use it to insert, extract and manage items reliably, and to keep inventories and storage actions in step across players and servers.
The library itself adds no blocks, items, mobs or dimensions and does not change gameplay; a player normally never notices it. It is intended to be installed only when one of the Unofficial Fabric Ports is used, and it requires Fabric API. Files are published for 1.20.1 and 1.21.1 on Fabric, with the 1.20.1-0.1.0.18 build as the most recent release and the source code and issue tracker available in public. It is open source under the GNU Lesser General Public License v2.1 only, and it runs on client and server.
