Smarter Furnace
by mert04c
Smarter Furnace lets one hopper placed above a furnace feed both its fuel and input slots, so a single vertical line of chests and hoppers can run the furnace.
What it does
Without the mod, a furnace needs fuel delivered from one side and smeltable items from the top, which often leads to bulky builds and wasted resources. Smarter Furnace changes that rule: items entering the top face of the hopper are checked, fuel such as coal, wood, lava buckets and similar items is routed into the fuel slot from the side, and smeltable items such as ores, raw food and sand go into the input slot as usual.
The mod is aimed at survival automation and at server owners who want simple furnace setups without complex redstone item sorters. It works with the standard Furnace and also with the Blast Furnace and Smoker, and it adds no new blocks or items, only changing how existing furnace mechanics behave. Smarter Furnace needs Fabric API. It is server-side only, so players join without installing it, and it is released under the MIT License but is not open source. Files exist for 1.21.1 only.
Key features
Single hopper feeding
One hopper placed directly above a furnace supplies both fuel and smeltable items.
Automatic item sorting
Each incoming item is checked, so coal goes to the fuel slot and iron ore to the input slot without extra sorters.
Works with furnace variants
The routing applies to the standard Furnace, the Blast Furnace and the Smoker.
No new content
The mod changes existing mechanics and leaves vanilla blocks and items untouched.
