  wiggle Y axis within a clamped value

  Posted by Craig Whitaker on January 7, 2011 at 3:14 pm

  Hello everyone,

  I have a 2D layer located at (200,400) that I would like to wiggle between it’s starting value and (200,100)

  I’ve been playing around for a day and am unable to fix the error that I’m getting from the following expression…

  I’m guessing that there needs to be a clamp function in there somewhere, just not sure what the syntax is and where it needs to be placed.

  Thank you,
  Craig

  wig=wiggle(10,300);
[value[0],wig[1]]

  How about this:

  [value[0],wiggle(10,150)[1] – 150]

  Hey Dan,

  Thanks so much, I appreciate it.

  If I understand this correctly, wiggle (10,150) could potentially wiggle between [200,550] and [200,250] because the starting value was [200,400]. By then subtracting 150 at the end, you’re forcing the upper limit to 400 and the lower to 100?

  Thanks again Dan.

  Best,
  Craig

  Yes, that’s correct.
