  Null + variance

  Posted by David Hildreth on October 14, 2011 at 9:10 pm

  I have many elements attached to one null with a change in position.

  I’d like to have all the elements to generally maintain the same movement, but with some degree of variance between them. Is there a way to easily add 10 or 20px of random difference between the position change in each element? I’m not exactly sure where to start.

  Do you just want a random offset? If so, either of these should work:

  maxOffset = 20;
  seedRandom(index,true);
  value + random([-maxOffset,-maxOffset],[maxOffset,maxOffset])

  or,

  wiggle(0,20)
