> Hi Me and my son are following Daniel Shiffman’s learn processing guide on YT. We are on creating objects and are want to make a bubble. This bubble is wobbling and rising but we also want it to pop when clicked on. It doesn’t need to be realistic but We are looking for a type of animation we’re the ellipse turns in to a point that falls down. Also a small number of particles “exploding” from the ellipse when it disappears… Can anyone help us with this code? If so. Please comment in code si…
