Mechanical Factory
by elmartino4
Mechanical Factory is a Fabric mod for servers that adds factory-style machines, in which a sieve turns stone, cobblestone, tuff and sand into a set of mixed outputs.
What it does
The mod is server-side only, so players join without installing anything and only the server needs the jar. Its feature set centers on a sieve-like machine that takes a block or a mixed pair of inputs and returns a result from a recipe. The recipe pairs include cobblestone with gravel, tuff with gravel, andesite with sand and stone with sand. A demonstration of the sieve ships in the mod, and an earlier version of that demo was changed slightly to follow the current recipe format.
Recipes are read as objects whose inputs may be mixed. A recipe flag decides whether the inputs must be given in a fixed order; when it is false, the mod also accepts the inputs in any order, and a mixed-field default is true. The mod requires Fabric API, and it is published for Fabric only, in two game versions, 1.17.1 and 1.18.1. The code is under the MIT License and is open source, with a source repository, an issue tracker and a wiki linked from its public pages.
