Talk:Clearance/Room space has no real influence on thought, but clearance within a ~4.5 radius does
As of version 0.15.1284 (compiled September 2, 2016), I tested in-game that friendly colonists, the Yorkshire terrier (dog), and neutral visitors, don't detract from clearance (they have no effect). So I presume that the subject colonist also has no effect. And, that the threshold for the thought "Spacious interior", which gives +5 mood, is between 48 and 48.5. That is, 48.5 clearance grants the spacious thought, and 48 does not. I know that the number used to be different, the article was once correct, so it was changed in an update at some point. The thoughts page still uses the old numbers for spacious interior (not anymore I fixed it), and it links to this page. As for the other comment here, there are 69 viewed tiles which influence clearance, not 100, again according to my in-game testing. It's all blocks within the current room within the radius [sqrt(20), 5.0). That is, the sight radius for clearance is >= sqrt(20) ~= 4.472136, and < 5.0. This is a 9x9 square with 3 tiles taken off of each corner (9*9 - 3*4 = 69). It's been a while since I was somewhat familiar with the code structure of this game, so I can't find the exact number right now, but you could say it's all tile centers less than 5.0 away.
"Space" seems to have no mechanical relevance to the game at all, so perhaps the article is misleading. The thresholds for the "space" labels of "room stats display", they really don't mean anything. I didn't bother testing the thresholds for cramped, but know that up to 69 tiles contribute to clearance (tiles within a radius less than 5.0), and that 49 clearance total gives the "Spacious interior" thought, while 48 does not. 48.5 is also "Spacious", via 49 - 0.5 from an added standing lamp (but two lamps, 49 - 0.5*2 = 48, is not spacious).
I know for certain the clearance threshold used to be >= 26 for spacious, now it's > 48.
edit: I was just going through old notes files, and looks like it was 69 tiles at least a year ago as well. I'll update the pages.
"CLEARANCE (NOT BEAUTY, though it uses the BeautyUtility class)
I very roughly approximate, that SampleNumCells_Space is 69."
edit: I was able to peruse the code again. Visible tiles for clearance is 69, and multipliers for thresholds are 0.7, 0.3, and 0.01. So, 48.3 clearance for spacious, 20.7 for cramped, and 0.7 for very cramped. So, very cramped is impossible, and it has been since before the change from 26 to 48, I think. I put a colonist in a 1x1 room, and they were still only cramped, so while very cramped is in the code, it is effectively impossible unless you can trap them on top of a standing lamp in that 1x1 room. I'll probably remove it from this page, or make a note. There's also some other oddity where the enumeration doesn't match up with the effect, the code has a lot of issues and inconsistencies all over. But for calculating clearance, tiles which are "walkable" but not "standable" detract 0.5 (animals (& people) don't count however, only static tiles). Tiles which are not "walkable" detract 1. Doors are not part of the room. Whether a tile slows you down to walk on makes no difference.
edit: One more thing! I just did in-game testing to confirm, that standing lamps and beds are 0.5 clearance detract per tile, and they have been for well over a year, the mechanic is the same as it used to be. They are walkable but not standable, so they detract 0.5 *per tile that they occupy*. So the post below me that says beds are 1 per tile and 2 total, it's wrong, it's still 0.5 per tile, so a bed is 1 total.
edit: Ahh, all done, updated this page and the Thoughts list page.
