Sure, Sandy created a lot of problems. But I got an idea while sitting in my room without a light for a week...

So, finally I was able to run my first c++ code this evening, and this code implements a very fast 3D lighting system for DF. I hope parts of it will be used in DF one day...





I have to finish and optimize my c++ code (multithreading, caching, all that smart words), but it's the right time for suggestions.
I've got a couple of them.
1) by default, all underground caves and mines are always dark. So, dwarfs should keep the lights on.
2) light can be obtained by burning booze, wood, lignite and all other flammable materials. So, a light source consumes resources. Dozens of farms may be required for a large fortress.
3) fear of the dark. Dwarf caught in a dark becomes mad\depressed very soon and can be cured only by the sunlight(or a booze from the sunshine). Evil regions are always dark outside. More fun
4) evil areas may spawn evil ghosts that arise inside unlit areas of the fortress
5) forgotten beasts are not visible in unlit areas.
6) underground creatures are very happy to destroy light sources
7) dwarfs may process underground plants or seeds to get a source of light \ fuel

What do you think, guys?

[Cool Guy]

I actually really like this idea, I don't think they should have to burn resources like that though, maybe a light that can be powered by windmills/waterwheels or a lamp that takes oil or fat.

[NAV]

I usually imagine dwarves using some sort of bioluminecsence. Maybe dwarves use glow in the dark mushrooms as light sources, and some sort of glow in the dark pet creature as a portable light source.
torches and lamps and bonfires are cool too.

[Drapestar]

this is awesome! 

i think all those methods to create light would be good with the use of a camp fire or bonfire or fireplace like object.

for more sustained light though i think some sort of lamp or candle object could be created. candle made from thread and wax? lamp be like as cool guy said takes oil or fat and would be made of metals.

That's a cool idea. Maybe they also have really good night vision?

Love the demo, this pretty much conveys how awesome I've always imagined lighting would be.

There is an official lighting thread from years back that has lots of discussion and a summary of points by Footkerchief iirc.  On my phone now so linking is troublesome.

Should be said that lighting is a MAJOR development that would need fundamental changes to pathfinding and general ai to make it work.  I'd encourage everyone who likes this demo to vote for lighting on the eternal suggestions page!

They should have.

Some of the cavern mushrooms/animals might also have light sources, albeit for different reasons. (attract panicking animals, and then gobble them up)

[therahedwig]

I suggest that individuals can see around them regardless of light. But nightvision creatures, such as dwarves should be able to see two or three tiles surrounding them, and humans only the first tile next to them, or something. Then they can carry lanterns to expand that view, and build lightsources for stationary light.

Maybe dwarves can make like chain oil lamps? Where the oil reserves are linked so that it will only take one job to light a series of oil lamps. Or maybe there's one lighter-dwarf(set in noble menu) that just goes around the whole fortress continuously to make sure all lights are dealt with?
It's extremely prey to unwieldy micromanagement.

Anyhow, adventure mode already has field of vision that decreases as there's less light. The main problem would be that DFs display needs to be updated for display different lightness-levels.

Also, Day and Night?

[Broken]

Magma should emit light as well. Some time ago, i though a magma based lighting sistem.
Build the fortress in alternate z levels (11,13,15,etc), with grate floors and magma filled levels in between. Eternal free light.

I don't know if you've ever been underground but without light darkness can be total. You seldom get this on the surface. In adventure mode it would have to let you know when you are bumping into things somehow, using text perhaps.

Cave adapted dwarves should get used to the dark and be able to see better in it.

[AutomataKittay]

With above comments, I've been wondering if there'll be provision for infrared vision and the like. I imagine it could happen with some of the dark vision stuff, at least for creatures supposedly adapted to living underground ( though they tend to just end up losing ability to see ).

[GreatWyrmGold]

I'd like it if you could always "see" at least the nine tiles adjacent, at least if they were walls, floors, or empty space, and if there was a creature there. It would be annoying if not.

Oh, and in case you hadn't gathered...planned.

Oh, before I forget, I'd suggest putting that script on the modding subforum.

[nop]

Well, that's not a dfhack-like script but a separate c++ program at this moment.

[GreatWyrmGold]

Is it easily applied to Dwarf Fortress?

[MrWiggles]

This is great, except that its entirely to superficial.
