randomly fade dots?

DavidF

Hi, A very basic question here. I am totally new to this. I have 3 dots, Red,Yellow,Blue. I simply want to make them fade in and out independent of each other and at random intervals. Would be also nice to shift saturation as another fading elements in each. How do I do this? Here are the dots I made. void setup() { size(1200,800); background(0); }

void draw() { stroke(255,3,5,127); fill(255,3,5,40); ellipse(300,400,200,200);

stroke(250,251,5,127); fill(250,251,5,40); ellipse(600,400,200,200);

stroke(0,0,255,127); fill(0,0,255,40); ellipse(900,400,200,200); }

You should define a Dot class in order to have 3 independent dots w/ their own properties.

And of course, store those 3 object references in an array:

An online example which just does those:

Thank you GoToLoop. Likely way over my head here but that gives me more to tinker with and learn.
