It could be complicated, if you have to compensate for every level of comp nesting. However, I’m guessing that going up the heirarchy, there aren’t many instances where the nested comp layer doesn’t start at time = 0 in its parent comp. If you can identify those situations, it will simplify the code.

Something close to this maybe:

p = toComp([0,0,0]);
w = thisComp.width/2;
h = thisComp.height/2;
center = [w,h];
maxD = Math.sqrt(w*w + h*h);
d = length([p[0],p[1]],center);
easeIn(d,0,maxD,100,0)

I have no explanation for that. Maybe someone else will chime in…

It’s in the Expression Language Reference section of the AE Help. It’s in the Property attributes and methods section (although it’s not very well marked–it’s actually in the propertyGroup writeup).

I’m sorry, can you post a screen shot that shows what’s happening?

Probably some variation of this, linked to the SoundKeys output:

http://www.motionscript.com/design-guide/audio-trigger.html

substituting an x position animation for the scale wobble. Something like this maybe:

amp = 100;
rampTime = .25;
fallTime = .1;
x = t < rampTime ? easeOut(t,0,rampTime,0,amp) : linear(t - rampTime,0,fallTime,amp,0);
value + [x,0]

In that case, I would change it to > -1

Something like this:

count = 0;
for (i = 1; i <= index; i++){
  if (thisComp.layer(i).name.indexOf("Control Layer") == 0) count++;
}
count

I’m not sure what you mean by intensity, but you could convert RGB to HSL. This would give you the lightness channel, for example:

c = colors.sampleImage(colorPicker, radius = [5, 5], postEffect = true, t = time);
rgbToHsl[2]

Yes, unfortunately. You might be able to simplify somewhat with a clever naming convention. For example, if you named your flash layers “Flash 1”, “Flash 2”, etc. and your control layers “Control 1”, “Control 2”, etc. then you could do something like this in the Flash expression so it would be the same for every layer:

myNum = name.split(" ")[1];
segStartTime = thisComp.layer("Control " + myNum).effect("Slider Control")("Slider");

You could do a similar thing with the audio expression.
