  Need to loop wiggle to create seamless animation

  Posted by Erikk Lee on October 24, 2017 at 5:56 pm

  I have a simple 15 sec animation where I am using wiggle to make grass and flowers sway.

  I’m using…

  wiggle(.5,15)

  …and that’s it.

  How do I get it to loop seamlessly?

  wiggle(.5,15)

  Here’s a 5-second loop:

  loopTime = 5;
  t = time % loopTime;
  wiggle1 = wiggle(.5, 15, 1, 0.5, t);
  wiggle2 = wiggle(.5, 15, 1, 0.5, t – loopTime);
  linear(t, 0, loopTime, wiggle1, wiggle2)

  You put your layers in a precomp. Add time-remap to that precomp. Add this expression to the time-remap.
  cycleDuration = 2;
cycleDuration-Math.abs((time-inPoint)%cycleDuration *2-cycleDuration )

  You can modify the duration of the loop by changing the 15 in the first line. This is basically a “pingpong” loopOut with the duration of 15. As an alternative, you can set a keyframe at 0 and one at 15 seconds of the timeremap propriety of your precomp, and add this expression:
  loopOut("pingpong")

  Dear Dan,

  I was wondering if there is a way of making the typewriter effect follow audio levels.

  example:

  After effects needs to say: When the audio levels are 0 , the typewriter shouldn’t go on. If higher the animation should go on.

  What I mean by this is, that the animation stops when there are breaks in like a voice over.
  This is how far I got, I’m very new to this and I am trying to learn it.

  Please help, it would save me so much time !

  Yours Sincerely,

  Yoran

  slider = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider") if (Both Channels < 0,1 ) 0 else 100
