  bobbing clouds

  Posted by Craig Hellen on June 13, 2009 at 1:56 pm

  i apologize if this has been asked lots before and i didnt manage to find it in my searches…
  I have a comp where i have titles appearing on clouds, i would LOVE to be able to have an expression to set the vertical position of them to displace in a nice smooth motion.

  curently im doing it with keyframes but id love to know if there is a simpler way of doing it with an expression.

  I gotta learn expressions sometime and figured this would be a good way to get my head round them 🙂

  Hi Craig,

  If you just want random bobbing motion you should use a wiggle expression. It’s the easiest expression there is and a good place to start learning. You just alt+click the stopwatch for the property you want to animate (position) and type into the box:

  wiggle(5,10)

  This will make the layer move by 10 pixels 5 times a second.

  If you would like to move the clouds only in the vertical, you’ll need to use a very slightly more complicated expression. But I explain how to do that in this video tutorial:
