Jem's Fueled Campfires does what it says on the tin: campfires need fuel to burn.

By default, campfires place unlit with some initial fuel. But once it goes out, you will need to toss some more fuel on top to light it!

Unsure what is going on with the fire? Use your Fire Poker to investigate! It will show remaining fuel time, bonfire, and "eternal" status. How this message displays can be configured in the client config.

Note: You can disable needing the Fire Poker in the server config, allowing you to sneak+right click with an empty hand instead.

Nearly everything is configurable or disableable (server-side) via the server config (see FAQ's). Additionally, most features are individually configurable between regular and soul campfires!

Available features included but not exclusive to:

Campfires can be made eternal (burn with no fuel loss) for decoration, and can lose this status if used to cook. The item needed is blaze powder by default, but can be configued using the tag "jc_eternal_fuels". Structure-generated campfires are eternal by default (and immune to rain).
Rain will rapidly deplete fuel by default, but can be set to immediately extinguish campfires. Hide them under shelter to be safe!
Fuel values and usage rate can be changed, as well as initial campfire fuel and maximum stored fuel.
Campfires do not tick needlessly (outside of regular vanilla stuff) unless lit, so build away lag-free!
Campfires take turns grabbing fuel, so if there are adjacent campfires, one won't hog it all! Additionally, fuels will not "duplicate" when thrown onto multiple campfires at once.
Campfires can become dim when low on fuel, for that extra ambiance! [Warning: Potentially Buggy - Disabled by default]

The following are potentally destructive behaviors and are also disabled by default:

Lit campfires can spread fire to adjacent flammable blocks. Maybe build a brick hearth when keeping it indoors, or a classic cobble fire-ring to make Smoky the Bear happy and prevent forest fires.
Bonfires happen when too much fuel is added. They can rapidly spew fire and embers up to two blocks away, cook food faster, and burn fuel quicker. A simple fire-ring won't cut it… No need to panic, just put it out to restore it to normal!

Especially useful for mod-pack development:

The tag "cf_filtered_fuels" (and "soul_cf_filtered_fuels" respectively) allows you to either black- or white-list fuel items. Black/whitelist behavior is set through the server config for both regular and soul campfires.
A fuel override datapack option lets you set custom fuel values in ticks, even for something like diamonds! Template/details are in the FAQ's.
Valid eternal items are configurable with the tag "jc_eternal_fuels".
Client debug options allow one to show messages in the chat window (for persistent logging) as well as to display the fuel in ticks.

FAQ:

Q: Where are the server configs?

A: This varies depending on your version:

Pre-Neoforge 1.21.1, the server configs are in the "defaultconfigs" folder. When you create a world, these configs get copied to it. Changes in the "defaultconfigs" folder WILL NOT affect existing worlds, which need to be manually edited in their save file.
In Neoforge 1.21.1+, defaultconfigs is no longer used. Now, the configs folder WILL apply to exiting worlds. This can be overridden at world creation with a custom config.

Q: How to use the fuel overrides?

A: The overrides work like tags, where modpack devs can use "replace" to override any mod-designated data. Entries can be a list of items or a \#tag.

The file "fuel_overrides.json" gets placed in the folder "data/jemscampfires/fuel_overrides".
Template:
{
"replace": false,
"fuel_overrides": [
{ "fuel_ticks": 200, "input": "#minecraft:buttons" },
{ "fuel_ticks": 600, "input": [ "minecraft:spruce_log" ] },
{ "fuel_ticks": 40000, "input": [ "minecraft:spruce_trapdoor",
"minecraft:oak_trapdoor",
"minecraft:diamond" ] }
]
}

Q: Porting to other versions/loaders?

A: I will port to newer Neoforge versions, but I have no plans to downport below 1.16.5, to Fabric, to Bedrock, or to continue Forge support. Anyone is free to do so, please just credit the original mod! :)

Q: Features or compatibility requests?

A: I am always open to ideas and requests! No promises that they can or will be added, of course.

Confirmed compatibilities:

Farmer's Delight:

Works with the Stove Block! Also, fuel detection hitboxes are wide enough for skillets and pots.
FD compat got broken in 1.20.1 by FD v1.3/1.3.1. Fixed by v1.20.1-1.6.2 version! This new version will not work for older, pre-1.3 Farmer's Delight. Continue using v1.20.1-1.6.1. Also, Neoforge v1.21.1+ versions will only target FD 1.3+ for compat.

Starlight/Moonrise:

Will not crash when using dynamic fuel lighting

Build Your Campfire:

Config option "enableCampfireBuildCompatibilityFix" needs to be set to "true"

Campful:

Soul campfire issues are on Campful's end, as far as I can tell

Hourglass:

Campfires use fuel when you sleep if "blockEntityEffect" is set to "SLEEPING" or "ALWAYS"

Porting to any newer versions is planned. Poke me if you want it done sooner :)

Of course, anyone can use this mod in a modpack!
