v1.1.0·Updated 2026-09-30

Fires keep while you are away. A single absence costs one fuel, however long it was.

About this mod Author’s original text

Vaka

Vaka does two things to fires. It caps what a fireplace loses while nobody is there, so a

single absence costs at most one fuel however long it lasted. And lights that burn resin or

coal hold each unit twice as long. Cooking fires burn wood, and while you stand at one it

burns exactly what vanilla says.

Features

  • A fire is charged at most one fuel for any one absence. The amount is configurable.
  • A fire that burns resin or coal lasts twice as long per unit, whether you are there or not.

Which fuels count and how much longer are both configurable.

  • Wood fires burn exactly as vanilla, to the decimal, while you are at them. Sleeping and

skiptime are charged in full at the fire's own rate, because the fire was loaded and

ticking the whole time.

  • Covers every piece that uses the vanilla Fireplace component, including fires added by

other mods.

  • No new pieces, no keybinds, no UI, no new saved data. One Harmony postfix on one method.
  • A log line each time you enter a world, naming the fires the light rule applies to.
  • Optional logging that reports what each catch-up was worth and what it was actually charged.

How it works

A fireplace does not burn in the background. While its zone is loaded,

Fireplace.UpdateFireplace runs every two seconds, asks how long it has been since the last

run, and subtracts that many seconds of fuel. When the zone is unloaded nothing runs and

nothing re-stamps the timestamp on the fire's network object, so the gap keeps growing. The

first update after your base loads back in pays for the whole gap at once. Whether anyone was

present is never part of the sum, so a base of thirty torches is thirty of those bills landing

in the second you walk in.

The clock is world time, not wall time. A dedicated server only advances it while at least one

player is connected, and the value is saved into the world file. An empty server is frozen and

a single player world resumes exactly where it stopped. What actually drains your base is the

hours other people spent online elsewhere on the map, or in single player, the hours you spent

across it yourself.

Vaka caps that first bill rather than making all fuel last longer. A longer fuse on every fire

would make cooking cheaper while you are stood at the campfire, which was never the problem,

and a longer trip next time would still arrive at a cold base.

An absence is recognised by the fireplace object not having been running, not by the size of

the gap. The game creates a fireplace when its zone loads and destroys it when the zone goes,

so the first update for a new object is the one paying off however long it was away. Every

later update is a live tick and is charged in full whatever its size. That is why sleeping

through the night and the skiptime console command still cost full price.

Light fuels

The second rule is a longer fuse, and only for light. A fire whose fuel is on the

LightFuels list burns each unit LightFuelMultiplier times as long. The defaults are resin

and coal, twice as long. It applies all the time, at the fire and away from it.

It stays off cooking fires for the reason the cap is a cap. A longer fuse on a campfire makes

cooking cheaper, and nobody asked for that. On a torch it only means fewer rounds of the base

with a stack of resin.

A cooking station or cauldron does not ask for a campfire. It looks for the burning area a

campfire carries, and the standing brazier carries one under the same name. If the rule

reaches a fire with that area and a cooking station fits over it, that spot cooks on the

longer fuse. Nobody has tried it. The log line below names any fire the rule reaches that

carries the area.

The rule reads what a fire burns rather than which piece it is, so a torch from another mod

that burns resin is covered without anything to update. Which pieces burn resin or coal is the

game's own data, so each time you enter a world Vaka writes one line to the log naming the

fires the rule applies to, grouped by fuel. A fuel on the li

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
