Polyenergy
by Arzumify
Polyenergy gives server-side mods a simple energy system that entities and networks can use, with its size set by an extension.
What it does
Polyenergy is a dead-simple energy mod for Fabric and Quilt, and it runs on the server alone. Players join without installing it, and clients need nothing. The mod provides a shared energy layer that other server mods can build on, including energy stored by entities and carried through networks.
Files are published for Fabric and Quilt across five game versions, with 3.0.0 for 1.21.4 as the latest file. The code is open source under the GNU General Public License v3.0 or later. Source code and an issue tracker are linked from the project.
Key features
Simple energy layer
A basic energy system that server-side mods can read and write, without a separate energy framework.
Entity energy
Energy can be attached to entities, so mobs and other entities on the server can hold and spend power.
Network transfer
Energy can move through networks, letting connected machines share what they store.
Adjustable size
An extension controls the size of the energy system, so the same base can scale to larger setups.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
