How to make my shape move on a curve?

samwisegodfrey

Hey! This is my first project using Processing. I decided to make a little landscape with a mouse-dependant animation of sunrise/sunset. It's obviously very crude, but my problem right now is I've only managed to make the moon/sun move on two mirrored lines, as opposed to a nice curve, which is what I'd really like. Can anyone offer their help? Here's what I have so far.

void setup() {
  size(500,500);

}
void draw() {

    noStroke(); 
  if (mouseX<250) {
     background(mouseX/0.98,mouseX/0.98,0);
     fill(255,255-mouseX/0.98,255-mouseX/0.98); 
    ellipse(mouseX,150-mouseX/2.5,50,50);  
  } else {
     background(255-(mouseX-250)/0.98,255-(mouseX-250)/0.98,0);
     fill(255,(mouseX-250)/0.98,(mouseX-250)/0.98);
    ellipse(mouseX,50.4+(mouseX-250)/2.5,50,50);
  }

  fill(23,122,11);
  ellipse(80,220,100,100);
  ellipse(265,250,230,200);
  ellipse(500,310,200,300);

  fill(40,180,20);
  ellipse(0,270,230,230);
  ellipse(150,280,230,190);
  ellipse(260,275,120,120);

  fill(30,215,7);
  ellipse(55,370,250,250);
  ellipse(235,380,200,175);
  ellipse(415,320,320,300);

  fill(26,255,0);
  rect(0,400,500,100);

}
