Run (in place)

The run of the nine game cycles: a forward lean, a long stride fitted to a speed setting, the knees tucked high and both feet off the floor as the legs change over, looping for as long as a game is running the character.

What it is for

Run (in place) is the run of the nine game cycles: the gait a game plays once a character is running rather than walking. Like Walk (in place) it steps on the spot rather than travelling under its own power, while a game moves the character's own box across the screen. What a run adds over a walk is a forward lean, a long stride, the knees tucked high, the arms bent and both feet off the floor as the legs change over — the moment of flight a sprint has and a walk never does.

The principle it shows: exaggeration

Nothing in the run's mechanism is new: it is the exact same leg-angle formula the walk uses, fitted to the same speed setting. What changes is how far every number is pushed — a stride that opens past 35 degrees instead of under 30, a knee bend of 70 to 100 degrees instead of 30 to 50, no stance give at all, and a 10-degree forward lean and 7-degree head tip the walk never has. None of it is a new idea, only the walk's own numbers pushed further, which is exaggeration: taking a true motion past life-size so it reads clearly at speed.

Try this

Raise the running speed from 1.5 to 2.4 body heights a second. Both the stride and the loop quicken together, the fastest this run is fitted to go before the formula that keeps the foot from sliding is pushed past its working range.
In the program: params.speed 1.5 → 2.4
Turn the stance foot only a fifth of the way flat instead of six-tenths. Less of the shin's own angle is straightened out, so the stance foot stays tipped up on its toe rather than planting flush, a lighter, more sprinting-on-the-toes look.
In the program: params.feet 0.6 → 0.2

How it differs from Walk (in place) and Run in

Walk (in place) is the same mechanism with a shorter stride, a gentler knee bend and a stance give the run drops entirely. Run in is a one-shot entrance that hops a character across the scene from off to one side and never stops bouncing; Run (in place) steps on the spot and loops for as long as a game runs it.

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, body, arms, legs
4 legs (a dog)	yes	whole body, body, head, front legs, back legs, tail, ears
no legs (the monster with no legs)	yes	whole body, turns, body, arms, tail, ears
