functions in processing

For this assignment i divided the draw part of last “egg program” into functions. The variables that you can change in draw are the color of the sperms and the maximum size that the egg grows when mouse is inside.

here s the new code

// egg position
int x = 400;
int y = 300;
float radius = 20; // radius of egg
float angle = 0.0;
float anglevel = 0.1;//velocity of the tail
float amplitude = 10; // amplitud of the tail sine wave
// heads of the sperms
Float headRadius = amplitude*1.8;
float headx= 200;

int a=10;
void setup() {
size(800, 600);
smooth();
ellipseMode(RADIUS);
}
void draw() {
background(216, 80, 132);
tail(200,255,200); // three numbers to control color
spermHead();
egg();
mouseInEgg(200); // you can tell maximum radius of the egg.
}

void egg() {
noStroke();
fill(193, 30, 90);
ellipse(x, y, radius, radius);
}

void mouseInEgg(float maxEggSize) {
float d = dist(mouseX, mouseY, x, y);
if ((d < radius) && (radius <= maxEggSize)) { fill(213, 49, 100); text(“GET OUT!!”, 310, 300); radius = radius * 1.09; textSize(40); headx = 100; } // conditional to grow till maxEggSize radius if (radius >= maxEggSize) {
radius = maxEggSize;
}
// if mouse out from ovary return to normal
if (d > radius && radius > 20) {
radius = radius – 5;
headx = 200;
}
}
void tail(int red, int green, int blue) {
for ( int x = 100; x<=200; x +=4) {//the length of the sperm tail
fill(red, green, blue);
// 3 tails
float y4 = amplitude *sin(angle);
angle += anglevel;
ellipse(x, y4+height/4, 2, 2);
ellipse(x+100, y4+height/2, 2, 2);
ellipse(x, y4+height*3/4, 2, 2);
}
}
void spermHead() {
ellipse(headx, height/4, headRadius, headRadius);
ellipse(headx + 100, height/2, headRadius, headRadius);
ellipse(headx, height*3/4, headRadius, headRadius);
}
