  Add additional random seed to textIndex

  Posted by Kevin Dazet on April 17, 2013 at 10:09 pm

  Hi, does anybody know if there’s away to re-seed the randomness when you use an expression like this:

  seedRandom (textIndex, true)

  This bases the random seed on the text index, and I’m using it to assign random y positions to each character in a line of text. In some cases I’m not happy with the results, though. For example, I may have too many characters clustered together, and I’d like to have After Effects generate a new random order.

  Any suggestions?

  You could set a seed offset (and maybe tie it to a slider):

  seedOffset = 99971;
  seedRandom (seedOffset+textIndex, true);

  That’s exactly what I needed. Thanks Dan!
