Space

This article is considered accurate for the current version (Alpha 17B - 0.17.1557) of the game.

Space reflects a sense of being physically free and able to move around. It is harmed by spending extended periods in cramped rooms.

Mood table

Space Need Met	Clearance	Mood Buff/Debuff	Thought
0%	1 - 3	-10	Very cramped interior
1% - 29%	4 - 10	-5	Cramped interior
30% - 69%	11 - 40	No effect	No thoughts
70% - 100%	41+	+5	Spacious interior

Knowing the above information will help quickly determine the size of room you may be interested in. It has been worked out with empty, square or rectangular shaped rooms for ease, hence the small discrepancy between them.

The need will increase to maximum when a character is outside, but they are never affected by any space-related thoughts. When moving from the outside to a small room, they may temporarily have positive thoughts before the need drops.

Clearance

Clearance Sight Range

Humanoids take regular looks around their environment. Each time, they look at squares of flooring within their clearance sight range - a radius of 8 squares (193 observed squares). Squares outside the room the humanoid is in are not observed. Walls do not block this, as long as the room is the same; for example, if a room is almost divided by a wall in the middle, a human standing near the wall will still consider tiles behind the wall.

Calculating

Every tile that can be walked on counts for clearance, regardless of what items are there. Cells with beds, workbenches, lamps, plant pots, items, paws, dead bodies and anything else that can be walked across still count towards clearance. Cells with walls, comms consoles, nutriment paste dispensers, etc. do not count towards clearance because they cannot be crossed.

A character standing in the corner of a very large room will settle at 78% need, because they can see 56 tiles.

A character standing in the door of a room that leads outside will see the outdoors area, and their need for Space will met 100%, but they will consider themselves to be in a room, giving them +5 mood.
