Conifgure-Furnace-Speed

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
/furnaceSpeed
Displays 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
.//furnacespeed.cfg
and 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.

Compatibility
Minecraft 1.21.2 – 1.21.10
