```auto
void setup() {
  size(640, 360); 
  noStroke();
  rectMode(CENTER);
}

void draw() {
  background(51); 
  fill(255, 204);
  rect(mouseX, height/2, mouseY/2+10, mouseY/2+10);
  fill(255, 204);
  int inverseX = width-mouseX;
  int inverseY = height-mouseY;
  rect(inverseX, height/2, (inverseY/2)+10, (inverseY/2)+10);
}

```

hi Lin  
as you use the

- mouseX for left/right and
- mouseY for rectangle size

already  
how to make a additional up down?  
could use the mouseWheel  
[https://processing.org/reference/mouseWheel\_.html](https://processing.org/reference/mouseWheel_.html)

like in

```auto
float updown=0;

void setup() {
  size(640, 360); 
  noStroke();
  rectMode(CENTER);
}

void draw() {
  background(51); 
  fill(255, 204);
  rect(mouseX, height/2+updown, mouseY/2+10, mouseY/2+10);
  fill(255, 204);
  int inverseX = width-mouseX;
  int inverseY = height-mouseY;
  rect(inverseX, height/2+updown, (inverseY/2)+10, (inverseY/2)+10);
}

void mouseWheel(MouseEvent event) {
  float e = event.getCount();
  updown += 5*e;
}

```

from your title??  
you talk circle, but you make rectangles??  
check on  
[https://processing.org/reference/ellipse\_.html](https://processing.org/reference/ellipse_.html)

I don’t understand what that means.

Please explain using more words and more details.
