Gravity Generator
Most power generation in Minecraft modpacks follows the same tired formula: burn coal, spin a turbine, harvest the sun. The Gravity Generator add-on flips that idea on its head by turning gravity itself into a fuel source. Every mob, item, or creature that plummets into its intake chamber becomes raw energy, making this one of the most unusual and entertaining ways to keep your machines running.
What the Gravity Generator Actually Does
The core mechanic is refreshingly simple. Entities fall, and electricity happens. Place the generator so that mobs or dropped items drop into its top, and each impact is converted into Forge Energy, measured in FE. The further an entity falls, the more power it produces, which means a tall drop shaft becomes a genuine power plant rather than a decorative hazard.
Several generator variants are included in the add-on, each designed to catch falling entities on their upper surface. This gives builders flexibility: a compact single-block setup for small workshops, or a sprawling multi-generator array for industrial-scale energy farming. If you already run a mob farm, a slime chunk grinder, or even a chicken cooker, you are sitting on an untapped power grid.
Configuration Options That Matter
What separates the Gravity Generator from a novelty block is how deeply it can be tuned. Through the config file, you can adjust:
- Maximum storage capacity of the generator
- Maximum output per tick
- The ratio of falling distance converted into power generation
- Whether to use the entity blacklist (enabled by default)
- The entity blacklist list (empty by default)
- The entity whitelist list (empty by default)
That blacklist and whitelist toggle is the detail that keeps servers sane. By default the blacklist is active, so you can exclude villagers, pets, or named mobs from being harvested. Flip the setting to false and the whitelist takes over instead, letting you specify exactly which entities are allowed to generate power. Combined with the distance-to-power ratio, this means you can build anything from a gentle trickle charger to a brutal, high-yield drop tower.
Choosing Between Blacklist and Whitelist
For survival worlds, the blacklist approach is usually the safer starting point. You block the entities you never want consumed and let everything else fall. On public servers or themed packs where only specific mobs should count as fuel, the whitelist gives administrators precise control. Either way, the configurable maximum output per tick prevents a single generator from overwhelming your energy network.
Supported Versions and Loaders
The add-on is built for the Forge mod loader, which means it slots neatly into the vast majority of tech-focused modpacks. It supports the classic 1.12.2 era that many industrial packs still run, and it has been maintained for modern releases including 1.16.5 and 1.18.2. If you play on Fabric, check whether a port exists before planning a build around it, since the official releases target Forge.
Version compatibility is one of the reasons players appreciate launchers that handle dependencies automatically. With the foxygame.net launcher, for example, you can add the Gravity Generator to a modpack in a single click and let the launcher resolve the correct Forge build for your Minecraft version. That removes the usual guesswork of matching loader versions by hand.
How to Install the Gravity Generator
Getting started is straightforward for anyone familiar with modding. Here is the short version of how to install it:
- Confirm you are running a Forge profile for a supported Minecraft version.
- Download Gravity Generator for Minecraft from the official project page.
- Place the jar file into your mods folder.
- Launch the game once so the config file generates.
- Edit the config to set storage, output, and entity rules, then restart.
After the first launch, the config file appears in your instance folder. Open it with any text editor, adjust the values to match your energy needs, and save. Changes apply on the next game start. If you plan to run multiple generators, tune the output per tick first, because several units feeding one energy network can add up faster than expected.
Build Ideas and Practical Tips
A simple starter design is a three-block drop shaft above a single generator, fed by a spawner or a manual mob drop. For larger operations, stack generators side by side beneath a shared fall chamber and route the FE into an energy cell or directly into your machine bank. Keep an eye on entity despawn rules and chunk loading, since a generator only produces while its chunk is active.
Pair it with a mob farm and you effectively get free power from mobs you were already killing. The distance-to-power ratio in the config lets you balance realism against convenience, so a short drop does not have to mean negligible output.
Final Thoughts
The Gravity Generator is one of those add-ons that rewards creative thinking. It takes a mechanic every player understands, falling, and turns it into a configurable, scalable energy source for Forge-based Minecraft. Whether you want a small trickle of FE for a workshop or a full industrial drop tower, the tuning options give you room to experiment. Build the shaft, set the rules, and let gravity do the work.
