JAPTA by VpzomTrrfrt

JAPTA is a mod that adds a few neat blocks and items for the Redstone Flux power system.  I’d like some feedback, especially on balance.  Also, send suggestions and bug reports!

Here’s some things it adds (some haven’t been done for the 1.8 version yet):

Bonemeal Applicator: Takes Bonemeal from inventories next to it and applies it to the ground with RF.

Cake Converter: converts between Cake and RF.

Charging Plate: a pressure plate that only detects players and charges their items with RF.

Wooden Charging Plate (1.7 only): a wooden pressure plate that charges items with RF.

Chest Charger: Charges items in inventories next to it with RF.

Elevator: A multiblock consisting of an Elevator Top above some Elevator Shafts. Provide power to the Top, sneak from the top or jump from the bottom to travel through the elevator.

Flux Blaster: Provides RF to 8 blocks in front of it.

Flux Hopper (1.8 only): A hopper that transmits RF instead of items.

Item Blaster (1.8 only): Transfers items to 8 blocks in front of it.

Life Converter (1.7 only): In heal mode, heals living objects above or below it. In absorb mode, generates RF from living objects taking damage on top of it.

Mechanical Generator (1.7 only): Generates a small amount of RF from block updates.

Mover: Teleports entities above it (and in front of it in 1.8) forward. Also slowly transfers power forward.

Power Cabinet (1.8 only): A multiblock consisting of several Power Cabinet Shafts above a Power Cabinet Base.  The base holds 999 RF and each shaft holds 15000 RF.

RNG Quarry: Given a tool, mines a chunk-sized area below it, placing items in inventories next to it.

Time Machine (1.7 only): Uses RF to speed up time. Can be disabled with a Redstone signal.

Battery Potato: Allows you to eat RF.

RF Meter: Use on a block to read its RF content.

The JAPTA Book (1.7 only): Only available with Guide-API. Describes the mod ingame.

Apparently Patreon is a thing too


The RNG Quarry will mine blocks in a chunk-sized area below it using the supplied tool (provided it has RF to run).
Simply right-click it to give it a tool. If it has one already, that will be dropped.
The tool’s durability will go down for every block not mineable by a wooden tool.
Any items mined will be placed in nearby inventories (like chests) or simply spewed.

The Charging Plate is a pressure plate only activated by players, and charges their items if supplied with RF. The Wooden variation is activated by anything, and can charge items dropped on it.

The elevator is actually two blocks, the Elevator Shaft and the Elevator Top. Place the Elevator Top on top of the Elevator Shaft(s) and supply the top with RF, then jump from the bottom to go up or sneak on top to go down.

The Chest Charger will charge items in inventories placed next to it with RF.

The Cake Converter converts between Cake and RF. Right-clicking will change its mode between Deploy (RF->Cake) and Absorb (Cake->RF). It has a range of 4 blocks in each direction for cake absorption but only 1 up and down for cake placement.
The Flux Blaster provides power to all blocks up to 8 blocks in front of it. When placing it, it faces away from you. If it finds an Elevator Shaft, it will power the block above it (probably an Elevator Top).
The Flux Hopper is a hopper that transfers RF instead of items.
The Bonemeal Applicator, when given power and placed next to an inventory containing Bone Meal, will use the Bone Meal on plants in an 8x8x8 cuboid around it. Its decisions of where to apply it are similar to the RNG Quarry.
The Mover will teleport entities on top of it in the direction it is facing. It is most useful in long chains. It also provides power to the block in front of it, so you might only need to power the back of the chain.
Similar to the Flux Blaster, provides transfers items to 8 blocks in front of it.


The Battery Potato is an item that lets you eat RF in the form of a delicious potato.

Can be charged by the Charging Plate or any other block that charges items.

The RF Meter can be used on a block to read its RF content.
