  simple wiggle problem

  Posted by Zac on July 3, 2005 at 2:16 am

  I have a 3d layer that i want to just wiggle up and down, not side to side. I option clicked on the position stopwatch and put in wiggle(10,2) but nothing is happening. Am i missing someting here? I just want it to be a slight movement, but i can’t get any movement at all.

  You need at least 2 keyframes set for the Wiggler to work (they can be the same). If that were not the case, you wouldn’t have any control over where your layer ends up when it’s done wiggling. Hope I didn’t misunderstand you question.

  Try this: alt+Click on position, type this expression:

  freq=3; // frequence per seconds
  amp=50; // pixels

  y=wiggle(freq, amp)[1];
  [position[0], y]

  // adjust freq and amp as needed!

  I dn’t know why you can’t see your wiggle, did you click outside the area you pasted in the expression, then do a ram preview? It works OK when I do it.

  Here’s 3 seperate expressions for wiggling on only one axis of a 3D layer.

  //x only
  [position.wiggle(10,2)[1], position[0], position[0]]

  //y only
  [position[0], position.wiggle(10,2)[1], position[0]]

  //z only
  [position[0], position[0], position.wiggle(10,2)[1]]
