fire.ron

Campfires, stoves, cooking and burns. Read by the game’s rules: a change here changes how the game plays, and a world remembers the content it was made with.

About this file

Fire and cooking. Schema: zombye_sim::fire::FireTuning (checked on load; unknown fields are refused; every field may be left out for the default below). Saved with a world’s settings, so a world keeps the numbers it began with. All numbers are our own.

Campfires are built by a recipe (recipes.ron, places: Some(Campfire)), outdoors, and fed one item tagged “fuel” at a time from the fire’s menu. Cooking recipes (heat: true) need a lit campfire or a working stove within reach.

Fields

The file is one FireTuning.

assets/data/fire.ron. Every field is optional (these defaults).

Field	Type	What it is
reach	f32	Metres from a fire’s middle, or a stove’s footprint, that a survivor can cook at and tend it from.
hours_per_kg	f32	Game hours of burning each kilogram of fuel gives.
max_fuel_hours	f32	Most game hours of fuel a campfire holds.
build_ahead	f32	How far in front of the survivor a new campfire goes (metres).
spacing	f32	Fires kept at least this far apart (metres).
max_fires	u32	Most fires in a world.
indoors	bool	Campfires may be built indoors (fire doesn’t spread; off keeps houses standing).
burn_radius	f32	Standing within this of a lit fire’s middle burns (metres).
burn_chance_per_sec	f32	Chance a second of a burn while standing in a lit fire.
zombie_burn_per_sec	f32	Hit points a second a zombie standing in a lit fire loses.
crackle_noise	f32	A lit fire crackles: a noise this loud (metres)…
crackle_every_secs	f32	…every this many seconds.
light_radius	f32	At night a survivor within this of a lit fire is in its light…
seen_as_daylight	f32	…and zombies see them as if by this much daylight (0 dark, 1 full day).
stove_furniture	String	The furniture kind that cooks while its building has power.
stoves_need_power	bool	Stoves need power (off: they always cook, like gas).
