How to wave hands for space key?

[Larry Serflaten]

Paste the code below into a new program and see if this is close to what you want:

var keys = [];

var spin = 30;

keyPressed = function(){

    keys[keyCode] = true;

};

keyReleased = function(){

    keys[keyCode] = false;

};

var hand = function(x, y, a){

    a += 509;

    quad(x+sin(a-20)*15, y+cos(a-20)*15, x+sin(a-15)*35, y+cos(a-15)*35,

         x+sin(a+15)*35, y+cos(a+15)*35, x+sin(a+20)*15, y+cos(a+20)*15);

};

var guy = function(){

    if (keys[32]){spin = (spin + 6) % 360;}

    background(255);

    ellipse(100, 150, 60, 80);

    ellipse(100, 100, 50, 60);

    hand(50, 150, sin(spin)*30+31);

    hand(150, 150, sin(spin)*30+31);

};

draw = function() {

    guy(); 

};
