About SurtlingFuel

From Thunderstore

Use Surtling Cores as super-fuel in smelters and blast furnaces. 1 core = 4 coal equivalent + 2x smelting speed. Fully configurable.

SurtlingFuel

Tired of burning through wood to make coal? Put those surplus Surtling Cores to work! This mod lets you use Surtling Cores as a premium fuel source in both the Smelter and Blast Furnace.

Features

  • Surtling Cores as fuel — walk up to a smelter or blast furnace and add cores directly
  • 4x fuel value — 1 Surtling Core provides 4 coal-equivalent fuel (smelts 2 ores)
  • 2x smelting speed — ores process twice as fast while burning core fuel
  • Cores take priority — if you have cores in your inventory, they'll be used first over coal
  • Fully configurable — tweak all values via BepInEx config file

Configuration

After first run, edit BepInEx/config/com.dejan.surtlingfuel.cfg:

| Setting | Default | Description | |---------|---------|-------------| | SmelterFuelPerCore | 4 | Coal-equivalent fuel per core in the smelter (2 coal per ore, so 4 = 2 ores) | | BlastFurnaceFuelPerCore | 4 | Coal-equivalent fuel per core in the blast furnace (2 coal per ore, so 4 = 2 ores) | | SpeedMultiplier | 2.0 | Smelting speed multiplier while burning cores | | PreferCoresOverCoal | true | When true, cores are used before coal. When false, coal is used first. Client-side only. |
