Sit

Staying seated in the game cycles: the middle third of sitting, a long hold on the ground, a chair or a ledge, breathing and blinking, looping every 4 seconds until a game stands the character back up.

What it is for

Sit is the sit of the nine game cycles, the held middle third of sitting (sit down, sit, stand up): once Sit down finishes, a game switches to this loop and leaves the character seated, breathing and blinking, for as long as it is meant to stay there, on the ground, a chair or a ledge at hip height, by the same on setting the sit-down and stand-up share.

The principle it shows: overlapping action

The breath (sy, sx) and the head's own sway share the same four-second period but start at different points in it, so the seated pose does not hold perfectly rigid even while nothing else is happening. On a ledge specifically, a second, separate two-second sway is added to the shins, since the legs are hanging free rather than resting on the ground, one more layer on top of the breathing rather than a replacement for it.

• show the side view — the move is drawn in profile.
• if (on == 0): … — on the ground: the hips, legs, shins and feet are set to the ground-sit pose, the body's own position worked out from those same angles, the torso tipped back and the arms resting forward.
• if (on == 1): … — on a chair instead: the hips and knees are set to the chair's own angles.
• if (on == 2): … — on a ledge instead: the same leg angles as the chair, but the body's height is not worked out from them, so the hips stay up rather than dropping to the ledge.
• sin wave on sy · every 4 s · amp 0.01, sin wave on sx · every 4 s · amp -0.005 — a slow breath, the body stretching and narrowing a little.
• sin wave on head · every 4 s · amp 1.4 · phase 1.4 — the head drifts a little, offset from the breath.
• if (on == 2): … — on a ledge only, both shins also sway 8 degrees every 2 seconds, opposite each other: the legs hanging loose off the edge.
• possin wave on blink · every 4 s · amp 1 · phase 1.2 · power 40 — a sharp blink once every 4 seconds.

Written out in full, exactly as the engine prints them:

-h*leg/2*(sin((105)*pi/180) + sin(((105) - (75))*pi/180))

h*leg/2*(2 - cos((105)*pi/180) - cos(((105) - (75))*pi/180))

-h*leg/2*(sin((88)*pi/180) + sin(((88) - (88))*pi/180))

h*leg/2*(2 - cos((88)*pi/180) - cos(((88) - (88))*pi/180))

Try this

1. Sit on a chair instead of the ground (on 1 instead of 0). The hips and knees settle at the chair's own angles, 64 and 88 degrees, instead of the ground's 85 and 75.

   In the program: params.on 0 → 1

2. Sit on a ledge instead (on 2 instead of 0). The hips stay up at the ledge's own height rather than dropping down to it, and the shins pick up a slow two-second sway on top of the breathing, the legs hanging loose off the edge.

   In the program: params.on 0 → 2

How it differs from Sit down and Stand up

Sit down is the motion of getting into this pose; Sit is the long, quiet hold once it is reached, with nothing travelling any further. Stand up is what a game switches to when it is time to leave this pose behind.
