Cheer (bird, win)

The win of the game cycles for birds: a little hop with the wings thrown up and flapping hard, the beak open in a happy cry, 1.2 seconds from start to finish, for a game to play the instant the bird wins.

What it is for

Cheer (bird, win) is the win of the nine game cycles, written for the bird set: the same short, 1.2-second burst as Cheer (win), but a hop with the wings thrown up rather than a spring with two fists pumping, a bird's own way of celebrating.

The principle it shows: anticipation and follow-through

A small hop (the legs bending 20 degrees, the wings swept back) primes the cheer before the wings ever go up, storing the same kind of energy a crouch does before a jump. After the main wing-throw, the move does not stop dead: the wings keep flapping for over half a second in diminishing beats before easing all the way back to standing, the energy spent gradually rather than cut off.

show the side view — the move is drawn in profile.
look happy — the face changes to its happy expression for the whole move.
at the same time: — a small hop: the legs bend 20 degrees and the wings sweep back 30 degrees, over 0.14 seconds, the body kept in step so the feet do not slide.
set dx …, dy … — locks the body to match that hop.
at the same time: — the legs straighten back out while the wings swing up to 110 degrees, over 0.06 seconds: the wings thrown overhead.
set dx …, dy … — locks the body again.
glide dy (-0.05*h), left arm -130, right arm 130, left leg 10, right leg 10, left foot 10, right foot 10, mouth 0.6, head 10 over 0.14 s (out) — the body lifts a little, the wings reach further up and the beak opens in a cry.
glide dy 0, left leg 0, right leg 0, left foot 0, right foot 0 over 0.12 s (in) — settles back down from that hop.
for 0.54 s: — both wings flap 26 degrees and the head bobs 6 degrees, the happy flutter of the celebration.
glide left arm 0, right arm 0, mouth 0, head 0 over 0.2 s (smooth) — eases all the way back to a standing pose.

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

h*leg*(1 - cos(((0 + 20*sin((min(local/0.14, 1))*pi/2)))*pi/180))

-h*leg*sin(((0 + 20*sin((min(local/0.14, 1))*pi/2)))*pi/180)

-h*leg*sin((20)*pi/180)

h*leg*(1 - cos((20)*pi/180))

h*leg*(1 - cos(((20 + -20*pow(min(local/0.06, 1), 2)))*pi/180))

-h*leg*sin(((20 + -20*pow(min(local/0.06, 1), 2)))*pi/180)

-h*leg*sin((0)*pi/180)

h*leg*(1 - cos((0)*pi/180))

Try this

Keep the wings flapping for a full second instead of 0.54. More flaps fit in before the cheer eases off, a longer celebration for a bigger win.
In the program: for · s 0.54 → 1
Open the beak all the way (mouth 1 instead of 0.6) during the hop. The cheer reads as a full cry instead of a happy chirp.
In the program: ramp · to.mouth 0.6 → 1

How it differs from Flinch (bird, hurt) and Cheer (win)

Flinch (bird, hurt) is the opposite reaction on the same body, a recoil rather than a hop, and it is a third as long. Cheer (win) is the same idea for the upright set, two fists pumping rather than wings thrown up.

Works on

Worked out by the build: it plays the move in the engine on each body and checks what moves on screen. Nobody types this table.
Body	Moves?	What moves
2 legs (a person)	yes	whole body, turns, head, arms, legs
4 legs (a dog)	yes	whole body, head, front legs, back legs, ears
no legs (the monster with no legs)	yes	whole body, turns, arms
