Machines

Machines is a small mod that adds back the Mythril and Onyx furnaces that were removed from SimpleOres2 many versions ago. They operate exactly as they used to. The versions for Minecraft 1.14.4 and later add mythril and onyx blast furnaces and smokers.

SimpleOres is required for 1.14.4 and later.
SimpleCoreLib is also required for 1.16.3 and later.
SimpleCore API is no longer required for 1.14.4 through 1.16.1; it was required for 1.12.2 and earlier.

The Mythril Furnace has a customisable (2x by default) multiplier on fuel burn time, meaning the furnace will burn for twice as long on the same amount as fuel in comparison to the vanilla furnace.

The Mythril Blast Furnace (added 1.14.4./1.15.2) has the same multiplier on fuel burn time, and smelts twice as fast like a vanilla blast furnace.

The Mythril Smoker (added 1.14.4./1.15.2) has the same multiplier on fuel burn time, and cooks food twice as fast like a vanilla smoker.

The Onyx Furnace has a customizable (33% by default) chance to produce extra ingots on each smelt. The extra amount produced is also customizable (it produces 1 extra ingot by default). It is crafted similarly to the mythril furnace, except using onyx gems instead of mythril ingots.

The Onyx Blast Furnace (added 1.14.4/1.15.2) has the same extra output chance, and smelts twice as fast like a vanilla blast furnace. It is crafted similarly to the mythril blast furnace, except using onyx gems instead of mythril ingots.

The Onyx Smoker (added 1.14.4./1.15.2) has the same extra output chance, and cooks food twice as fast like a vanilla smoker. It is crafted similarly to the mythril smoker, except using an onyx furnace in the center instead of a mythril furnace.

More machines may be added to this mod in the future (like the above-mentioned blast furnaces and smokers were).
