Sequence of actions from array

I started working this up before the last post … so i’ll go ahead and share this method as well.

using millis() like in @Chrisir example is more accurate than this method btw.

ArrayList<ColorSwatch> colorSwatches = new ArrayList();
color[] cols = {#22223B, #4A4E69, #9A8C98, #C9ADA7, #F2E9E4};
int idx, counter = 0;

void setup() {
  size(600, 600);
  rectMode(CENTER);
  for (int i = 0; i < 5; i++) {
    colorSwatches.add(new ColorSwatch(new PVector(width*0.5, height*0.5), cols[int(random(4))], 100));
  }
}

void draw() {
  background(13, 17, 21);
  textSize(100);
  updateSwatch();
  colorSwatches.get(idx).display();

  counter++;
}

void updateSwatch() {
  if (counter % 100 == 0) {
    if (idx >=4) {
      idx = 0;
      counter = 0;
    } else {
      idx++;
    }
  }
}

class ColorSwatch {
  PVector pos;
  color col;
  int scl;

  ColorSwatch(PVector p, color c, int s) {
    pos = p;
    col = c;
    scl = s;
  }

  void display() {
    pushStyle();
    noStroke();
    fill(col);
    rect(pos.x, pos.y, scl, scl);
    popStyle();
  }
}
