    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.
