Persistent Shape with Mouse?

hi, please you need to understand that we are talking here about two very different
approaches, i call it

  • paint job
    i used a image “layer” by layer = createGraphics(720,400);
    where at mouse click the random colored circles are stored ( painted in )

  • draw job
    while @Chrisir stores the mouseclicks ( position ) in a list ( and uses a JAVA program here you need to translate )
    and at draw()
    the background() cleans all
    and a FOR loop draws all circles from the positions array.

i hope you see the very different ways to do it.

how to discuss the differences / advantages?
in a paint job you can clear all as show in my code,
but you would not be able “forget” single events ( like the delete the oldest when make a new circle )
what i very well possible with a array approach.

i not like that filled as i not see where i am painting over,
but that you see the random color already ( now i use it in stroke )
is a very good idea.
