O.F.Device (Ore Farming Device)

Devices farm ores by drawing on fuel and materials supplied to them, producing a certain rate of output. Their placed block can be recolored by using a stick on it, which changes only its appearance. Devices are removed with a pickaxe. Increasing a device's speed raises production and makes a greater variety of ores appear.

The mod includes the C Device, a cobblestone generator, and two C Feeders: the C Feeder, which takes cobblestone at layer 1 and cobbled deepslate at layer 0, and the C Feeder II. A hopper placed under a device can pull cobblestone out of it. Using a C Feeder consumes twice as much fuel as the vanilla furnace uses for the same items. Ore appearance rate grows with the number of players and villagers nearby, within a 5x3x5 area around the device.

The mod is client and server, so it has to be installed on both the server and the client. It is released under the MIT License and is open source, and it is published for Forge and NeoForge across 24 release versions, 1.16.5 – 26.3. Changing a config value needs a game or server restart, and in multiplayer the server-side config is the one that applies.
