What have you tried? You MUST try to write the code yourself.

You will need a setup() and draw() function. In setup(), you must call size(). Start with that!

Since you will have many dots on the screen, write a Dot class.

Where will a dot be? What color will a dot be? Can you make a dot? Can you draw a dot? Can you have many dots?

It’s really hard to help with general “how do I do this” type questions. Please try to [break your problem down into smaller steps](https://happycoding.io/tutorials/how-to/program) and take those steps on one at a time.

You might also want to read through this guide:

> [@Guidelines—Asking Questions](https://discourse.processing.org/t/guidelines-tips-on-asking-questions/2147):

> Summary (TL;DR) Ask complete questions to get better answers! Be specific. For example: I want to load an image. I tried using createImg() , and I expected the image to be on canvas, but what happened instead was the image showing up below the canvas. Isolate your problem and work in small steps. Share only the code directly related to your problem if it is part of a bigger project, and if something isn’t working, try the smallest code that could do the thing you want. Can we run your code to …
