About this project
What does Furnace-Speed add?
FurnaceSpeed — Fabric Mod
FurnaceSpeed is a lightweight Fabric mod that lets you control how fast all furnace‑type blocks process items. Whether you’re smelting ores, cooking food, or mass‑processing materials, you decide how many furnace ticks run per server tick. Perfect for technical players, automation setups, or anyone who wants to eliminate waiting time.
Features
/furnaceSpeedDisplays the current speed multiplier./furnaceSpeed <1–1000>Sets how many furnace ticks are executed per server tick. Example:20= 20× faster smelting.World‑specific configuration The value is saved in
./<world folder>/furnacespeed.cfgand automatically loaded when the world starts.Affects all furnace variants
Furnace
Blast Furnace
Smoker
Singleplayer & Multiplayer support Works instantly in singleplayer (player is OP by default). Requires OP level 2 on servers.
How it works
A Mixin injects into the static method AbstractFurnaceBlockEntity.tick(...). After the vanilla tick completes, the mod runs (multiplier - 1) additional ticks. A re‑entrancy flag prevents recursive calls, and the BlockState is re‑read after each extra tick to maintain vanilla behavior and invariants.
