Space reflects a sense of being physically free and able to move around. It is harmed by spending extended periods in cramped rooms.
|0%||1 - 3||-10||Very cramped interior|
|1% - 29%||4 - 10||-5||Cramped interior|
|30% - 69%||11 - 40||No effect||No thoughts|
|70% - 100%||40+||+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 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.
Every tile that can be walked on counts for clearance. It doesn't matter what's placed on it. Walls, comms consoles, and nutriment paste dispensers will block the tiles, because they also block the movement. Beds, workbenches, lamps, plant pots, items, paws, dead bodies will not.
A character standing in the corner of a very large room will settle at 78% need, because they can only see a 56 tiles.
A character standing in the door of a room that leads outside will see the outdoors area, and their need will increase to maximum, but they will consider themselves to be in a room, giving them +5 mood.
