  Noob question: decimal points in random() expression

  Posted by Ilias Papadopoulos on February 6, 2020 at 3:36 pm

  Hi all, I’m sure this is a very very basic question but I haven’t found any answer to this no matter where I look. I have the following expression that picks random numbers from minmax values:

  wiggle(random(1,2),random(20,100));

  but I want to be able and draw even smaller numbers, ie decimals, but when I write the following

  wiggle(random(.5,2),random(20,100));

  it simply doesn’t work. Also tried

  wiggle(random(0.5,2),random(20,100));

  It must be some sort of formatting/syntax problem, however I can’t find a simple definitive answer to that.

  Thanks

  What did you mean by this:

  “it simply doesn’t work”

  What were you expecting vs. what actually happened?

  OMG could it be that it works and it’s not doing what I expected from it? I expected smaller changes in motion as they are visible for example when adding wiggle on position and I go from

  wiggle(random(5,10),random(20,100));
  to
  wiggle(random(1,2),random(20,100));

  there’s a visible drop of change in motion, but when I go down to

  wiggle(random(.1, .5),random(20,100));

  then it shows no discernible difference. I expected it to be a lot less jerky with longer calm intervals. Maybe it doesn’t work that way?

  In general, I think animating the wiggle frequency isn’t going to turn out the way you hope. For more info, see this:

  I’m not sure what I’d recommend though…
