|0007585||Dwarf Fortress||Dwarf Mode -- Environment||public||2014-07-23 06:04||2014-09-12 11:42|
|Assigned To||Toady One|
|Target Version||Fixed in Version||0.40.13|
|Summary||0007585: Trees channel light underground|
|Description||Exactly what it says in the description - light passes vertically through trees. I suppose the idea is that you don't want there to be darkness under the branches, but it has the added effect of making areas light that are underground - if the tile in question is one tile below the central trunk.|
|Steps To Reproduce||Mine out an area one z-level below ground. Wait for a tree to grow above, or simply mine out the roots of existing trees. Press K and check the tile. It'll say it's light. This permits growing aboveground crops underground.|
I can confirm this bug. I just registered to report it myself.
Additionaly: upon removal of the tree, your underground lair will have an open ceiling where the tree used to be. I assume this is as intended...
|I wouldn't think that's intended, no. I suppose it makes sense in a way, but I don't think it's intended.|
As far as realism goes, it makes sense... if you dig out a room that has a tree for a ceiling, then remove the tree, you've removed the ceiling.
From a game mechanics standpoint, I assume that tree trunks work off the same base code as constructed walls, so that they block movement but leave full empty tiles (rather than a floor) when cut down. Otherwise trimming the branches off a tree would leave branch-shaped floors in the upper reaches, which wouldn't make sense.
|That part makes sense. The weird part is that trees act like glass would in real life, and channel light downwards through them - or at least pass light downwards. The light remains there permanently.|
Maybe there were holes between the roots that let light filter down or something.
As for the light staying after the hole was filled, DF has always been like that; try channeling out an area on the surface then covering it with a floor.
|Fairly easy to reproduce in 0.40.06 with 0006749 fixed.|
|In 0.40.09, if you cut down the tree first then the roots vanish and there is no problem with light coming down when you dig where the roots used to be. I don't know yet what happens if a new tree grows over a room. Perhaps they don't grow there.|
