今天來時做眼珠轉動

首先看到最基礎的

滑鼠轉動眼珠

void setup(){

  size(120,100);

}

void draw(){

  //float t = frameCount/180.0*PI;

  background(0);

  fill(255);

  ellipse(40,50,33,33);

  ellipse(120-40,50,33,33);

  fill(0);

  float t=atan2(mouseY-50,mouseX-45);

  ellipse(40+15*cos(t),50+15*sin(t),5,5);

  t=atan2(mouseY-50,mouseX-(120-40));

  ellipse(120-40+15*cos(t),50+15*sin(t),5,5);

}
