Pocket Generators
A Create addon that turns rotational power into resources.
Pocket Generators adds duplicators: kinetic blocks that copy the item placed in their filter as long as they receive enough rotation. Feed them a shaft, pick an ore or a block, and they will steadily push copies onto your belts or into your chests.
The item in the filter is never consumed. It only tells the duplicator what to produce.
How it works
- Place a duplicator and power it with rotation (shaft, motor, water wheel, anything Create).
- Right-click with an item to set the filter (the item to duplicate).
- The duplicator generates copies over time and pushes them into the belt or inventory on its output face.
- Right-click with an empty hand to collect the output. Shift + right-click with an empty hand to take the filter back.
- Wrench the block to change its output face (cycles through all 6 directions).
- (Brass tier only) Hold right-click on the top face to open Create's value dial and choose the batch size, from 1 to 64 items per cycle. Stress cost scales with the batch size.
The faster the input rotation, the faster the production. Each tier requires a minimum speed to run.
Tiers
| Tier | Minimum speed | What it can duplicate |
|---|---|---|
| Basic | 16 RPM | Cobblestone, coal, copper (ores and blocks) |
| Andesite | 32 RPM | Everything from Basic, plus iron, redstone and lapis |
| Brass | 64 RPM | Everything from Andesite, plus gold. Adjustable batch size |
| Netherite | 128 RPM | Nether resources only: quartz, glowstone, gilded blackstone, ancient debris, netherite |
| End | 256 RPM | End resources only: end stone, purpur, chorus fruit, shulker shells |
Basic, Andesite and Brass form a normal progression: each tier can duplicate everything the previous ones can.
Netherite and End are two separate branches built from a Brass duplicator. A Netherite duplicator cannot copy End items and vice versa.
Diamonds and emeralds cannot be duplicated, on purpose. Some resources should still be earned.
Crafting
| Tier | Recipe |
|---|---|
| Basic | 3x3 crafting table: cobblestone, iron nuggets, shaft, redstone |
| Andesite | 4x4 Mechanical Crafter: andesite alloy, iron, shaft, plus a Basic duplicator |
| Brass | 5x5 Mechanical Crafter: brass, precision mechanisms, iron, plus an Andesite duplicator |
| Netherite | 5x5 Mechanical Crafter: netherite, netherite scrap, precision mechanisms, plus a Brass duplicator |
| End | 5x5 Mechanical Crafter: shulker shells, ender pearls, chorus fruit, plus a Brass duplicator |
Full recipes are visible in game with JEI, which also shows which items each tier can duplicate.
Configuration
Minimum speed, stress impact and production speed of every tier can be tuned in config/pocketgenerators-common.toml. Ideal for modpacks that want a different balance.
Modpack makers can also add or remove duplicable items with a datapack: each duplicable item is a simple JSON recipe of type pocketgenerators:resource_generating. No code required.
Requirements
- Minecraft 1.21.1
- NeoForge 21.1+
- Create 6.0+ (required)
- JEI (optional, adds a recipe category for duplicators)
