void setup()

{

  size(1080,720);

}

int R=30;

void draw(){

  if(mousePressed)ellipse(mouseX,mouseY,R,R);

  R-=3;

  if(R<0)R=30;

}

colorMode()和fill()的應用

void setup()
{
  size(1080,720);
  colorMode(HSB,100);
}
int R=30,H=0;
void draw(){
  fill(H,100,100);
  if(mousePressed)ellipse(mouseX,mouseY,R,R);
  R-=3;
  if(R<0)R=30;
  H++;
  if(H>=100)H=0;

}
04.
random()和座標的應用

void setup()
{
  size(1080,720);
  colorMode(HSB,100);
}
int R=50,H=0;
int CircleX=540,CircleY=360;
void draw(){
  fill(H,100,100);
  ellipse(CircleX,CircleY,R,R);
  R-=2;
  CircleX+=random(30)-15;
  CircleY+=random(30)-15;
  if(R<0)
  {
     R=30;
     CircleX=540;CircleY=360;
  }
  H++;
  if(H>=100)H=0;

}
