  Looping Color Wiggle Expression

  Posted by Corben Marroquin on April 14, 2015 at 4:30 pm

  I have a grid of white circles that I’ve used expressions to wiggle and loop their opacity using script I’ve found here in the forums. I then added a color overlay to these circles and used wiggle again, shown below, to change each of their colors randomly over time. My question is how can I make the expression below loop seamlessly?

  w = wiggle(2, .5);
[w[0], w[1], w[2], value[3]];

  This should work:

  freq = 2;
  amp = .5;
  loopTime = 3;
  t = time % loopTime;
  wiggle1 = wiggle(freq, amp, 1, 0.5, t);
  wiggle2 = wiggle(freq, amp, 1, 0.5, t – loopTime);
  w = linear(t, 0, loopTime, wiggle1, wiggle2);
  [w[0], w[1], w[2], value[3]];
