When I was in a dilemma about how to redesign my painting system, this article by another blogger inspired me. In this painting system, not only the dynamic brush types are designed, but also the background color can be controlled, the dynamic and static modes can be switched, the pictures can be saved and "accelerated" or "time" can be stopped. Since the original blogger has attached the code, I won't repeat it here. This makes me realize that using p5.js can actually create such a fun Sketchpad, but there are still few brush types and optional colors at this time. I decided to improve on this basis.

It's coming！！！
