Yeah. The same I was trying to do with my “randomness” problem, but unfortunately I didn’t solve it out. Maybe your code can be adjusted to my situation somehow.

I think you should use seedRandom() function with layer index as a parameter. That will make “wiggle my wiggle” effect you described.

Code should be sth like that (I’m not sure). Just copy and position layers.

wiggleFreq = 2 // your frequency
wiggleMax = 100 // max opacity
wiggleMin = 0 // min opacity
seedRandom(index,true); // random number per layer index
wiggleAmout = random(wiggleMin,wiggleMax) // generates random opacity level
wiggle(wiggleFreq,wiggleAmout) // wiggles your opacity

I give up ;/

What I created is only a random offset that changes after each animation time. It doesn’t play the animation from the beginning. I guess there is no way to check what is the current value of time remapping.

My code was:

animDur = framesToTime(25)
numberOfAnims = Math.floor(time/animDur)+1 // plus fist run
seedRandom(numberOfAnims,true)
offset = random(0,2) // random duration 0 - 2 seconds
valueAtTime((time%animDur)-offset) // get the animation
