The OF Device which is added by this mod produces ores at a certain rate by consuming materials and fuel.

Note: this description is for v1.1.0 or later.

OF Device

OF Devices can be mined using any pickaxe.

The appearance of the OF Device block can be changed using a stick.

Modification

Modifying the device will speed up production and cause a greater variety of ores to appear.

GUI and Hopper Automation

• (1) Materials
• (2) Fuel
• (3) Products

Materials

• Cobblestone
• Cobbled Deepslate (1.18+)
• Netherrack
• OF C Feeder I
• OF C Feeder II

OF C Feeders can act as Cobblestone (device y ≥ 1) or Cobbled Deepslate (device y ≤ 0), and are not consumed. However, when using OF C Feeder I, it consumes twice as much fuel.

Fuel

The same items can be used for fuel as for the vanilla furnace.

Farming Efficiency

Appearance rate of ores increases with number of players, villagers, etc. (up to 3) around the device (5x3x5).

OF C Device

OF C Device is a cobblestone generator.

GUI

Hopper can be used to pull cobblestones from underside of the device.

Data Pack

Built-in optional data pack.

OF C Feeder T recipes [v13.0.0+]

ID: orefarmingdevice:feeder_t_recipes

A data pack to add OF C Feeder T recipes.

OF C Feeder T is the improved version of Feeder II with about three times the efficiency. This item can only be used with OF Device Mod 2.

This item's recipe becomes available when the built-in data pack is enabled.

Config

The mod settings are saved in the following files:

• NeoForge: (instance_path)/config/orefarmingdevice-server.toml
• Forge: (world_save_dir)/serverconfig/orefarmingdevice-server.toml

Restart the game when you change the config. In multiplayer mode, server-side config will be used.

• isCobblestoneFeederAvailable: whether OF C Feeders are available for devices (boolean, default value is true)
• enableFarmingEfficiency: whether mobs around device increase farming efficiency of device (boolean, default value is true)
• accelerateProcessingSpeedByMod: whether to accelerate processing speed of device by modification (boolean, default value is true)
• increaseFuelConsumptionByMod: whether to increase fuel consumption of device by modification (boolean, default value is true)
• deviceProcessingSpeed: [v12.1+] processing speed multiplier of OF Devices. Choose one value from "HALF" (x0.5), "NORMAL" (x1), or "DOUBLE" (x2) (string, default value is "NORMAL")

If you want to return to the fuel consumption of v0.4.x or earlier, set increaseFuelConsumptionByMod to false.

Modifying Product Tables

The products and their probabilities of each device can be modified using loot table in data pack. JSON files for the loot tables corresponding to each device are as follows.

Here is the formula for the corrected weight: weight + (farming_efficiency * quality).

In Minecraft 1.21 and later, the following directory name loot_tables has been renamed to loot_table.

The created loot table files are loaded into Minecraft as a data pack (see also: Data pack - Minecraft Wiki).

An example data pack for Minecraft 1.21+ versions: example_datapack_ofdevice_mc1.21.zip.
