Summary0001589: Constructed walls/floors do not block light
DescriptionOnce a tile is exposed to light it becomes permanently 'light', even if you build a roof over it.
Steps To ReproduceChannel a tile, then build a wall or floor there.
Additional InformationHaven't tested cave-ins on perma-light tiles, may or may not affect anything.


I know that this issue is (semi?)well-known. I figured I should go ahead and file a report since there didn't seem to be one.
Tagsfloor, Intentional/Expected?, light, wall

This is quite an old issue, dating back to before 40d.

still a feature, otherwise we wouldn't be able to build greenhouses

Since Toady hasn't commented on similar issues in the past (based on what I can find), it's debatable as to whether it's a bug or a feature.

Ideally, glass floors would allow light through while others wouldn't. Currently the reward/effort ratio for this is too low to be worth it since there's no benefit to having 'dark' tiles (none that I'm aware of anyway).

This has been the case ever since rewalling was first added. Its not intentional, but its unimportant and apparently a pain to fix.

Starting outside, I dug a downward stairway, then one level down and up/down stairway. Later I built a floor over the downward stairway to close off that entrance. The cell that is the up/down stairway immediately beneath the floored-over downward stair is now "Inside Dark Subterranean", so I don't think things are exactly the same as they used to be. It used to be the rule was once-lit then forever-outside.

It may be that stairs now work differently than channeling.

Once a tile is changed to above ground, it is always above ground.

Constructed floor tiles do not block light, creating a weird greenhouse effect. This issue is well known behavior from 40d.

Constructed walls (instead of floors) should make your tile dark again if desired.

>>>jgoodwin Interesting, I quickly verified this one. Be interesting to see if there's any other new quirks like this.

I really wish this would be fixed as it's quite an important advantage (that you shouldn't have) and also quite ruining in terms of immersion, IMHO.
