I just started playing Dwarf Fortress, and I'm curious as to why you can create an underground lair but never have to make lights or torches. Also, is there a day/night cycle in DF? I know the screen never dims or anything but I'm still not sure how to check what time it is in the game. Thanks for any help!
Simple: because Dwarf Fortress does not (as of this writing) implement lighting.
The closest thing it has is the determination of whether a tile is "inside" or "outside", which, for light, is approximately:
- For each x,y position on the map:
- Create a ray from the highest z-level and go down.
- If something blocks the ray then everything below that (x,y,z) position is dark, everything above it is light.
If something is lit and then covered back up it will still count as light.
There is also no day/night cycle in Fortress Mode, it does have a calendar system with days, months and years. In Adventure mode there is a day/night cycle.
