Fabric Energy API

by 32bitx64bit

Fabric Energy API gives Fabric mods a shared, standardized way to store and transfer energy, so energy-based mods can interoperate.

What it does

Fabric has long used its own reimplementation of an energy system while Forge provides a standardized one, which leaves energy mods on Fabric largely incompatible with each other. This API supplies a common interface that energy-using mods can build on, making them more compatible across the ecosystem. Energy is measured in Fabric energy units (FE), calculated per tick in a manner similar to how Forge handles it. Fabric Energy API is published for Fabric only, for 1.20.1, and needs to be installed on the client and the server. It is open source under the GNU General Public License v3.0 only.

What the author says

Very annoying that every modpack for Fabric uses its own library and reimplementation of a energy system, meanwhile forge has a standardized API that makes most (if not all) mods cross compatible, while Fabric is stuck with energy mods that need specific compatibility mods, and its just a general mess. We have a unit…
