Heavy Storms
by tr4shy
Heavy Storms makes thunderstorms strike more often around players, and adds a Lightning Capacitor block that stores Forge Energy from those real strikes.
What it does
During thunderstorms the mod spawns extra lightning bolts near players. The number and spacing of the added strikes can be set in the config, so a server can make storms mild or fierce. Lightning that the mod produces is real lightning, so it can ignite and damage things the way ordinary strikes do.
The Lightning Capacitor is a block that gains Forge Energy each time a strike hits it. Automation mods that read FE can draw from its stored energy, because the mod exposes that energy via the usual Forge capability interface. Heavy Storms is server-side only: players join without installing it, and it changes nothing on the client. It is open source under the MIT License and ships for Forge and NeoForge on 1.20.1 and 1.21.1.
Key features
Extra lightning during storms
Additional strikes fall around players while a thunderstorm is active, with the frequency adjustable in the config.
Lightning Capacitor block
A block that collects energy from lightning strikes that land on or near it.
Forge Energy output
Stored energy is offered through the Forge capability system, so cables and other energy-reading machines can take it.
Real strike behavior
Strikes from the mod behave like vanilla lightning, including fire and damage effects.
