Thanks Kevin, that works pretty well. I used that idea coupled with Dan Ebberts’ genius scripting below:
freq = 1;
amp = 110;
loopTime = 3;
t = time % loopTime;
wiggle1 = wiggle(freq, amp, 1, 0.5, t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t – loopTime);
linear(t, 0, loopTime, wiggle1, wiggle2)

I scripted the frequency, amplitude and loopTime to sliders so I could control them across dozens of layers for a random but seamless loop. Thanks everyone!

Ah yes that would work for most particle effects but I need the same particles to each return to their original position as if they are flying in elaborate looped circles. I’m basically simulating fireflies dancing around the screen but they should return to their initial position to complete the loop without having them die off and be replaced by new particles. Is there a script to give random smooth motion around the comp and then return to their original spot, using a seed to ensure each layer is on a different trajectory?

Perfect. Thanks Dan, you rock!

Dan,

The countdown/up script on your website is super helpful and very customizable so thank you for that genius piece of code.

I noticed that the counter seems to round in the wrong direction when counting. Here’s an example of it counting down: 59.02, 59.01, 58.00, 58.99, 58.98
Is there a simple code solution related to the padding that I can use for this?

Thanks!

rate = -1;
clockStart = 600.00;

function padZero(n){
if (n < 10) return "0" + n else return "" + n
}

clockTime = clockStart + rate*(time - inPoint);

if (clockTime < 0){
sign = "-";
clockTime = -clockTime;
}else{
sign = "";
}

t = Math.floor(clockTime);
hr = Math.floor(t/3600);
min = Math.floor((t%3600)/60);
sec = Math.floor(t%60);
ms = clockTime.toFixed(2).substr(-2);
padZero(min) + ":" + padZero(sec) + "." + ms
