I think you have to iterate through the parent chain, so it would be like this:

L = thisComp.layer("Layer Control");
s = L.scale;
while (L.hasParent){
	L = L.parent;
	s = [s[0]*L.scale[0]/100,s[1]*L.scale[1]/100];
}
s

Something like this maybe:

s = thisComp.layer("Null 1").effect("Slider Control")("Slider");
if (numKeys > 0){
  idx = clamp(Math.round(s),1,numKeys);
  valueAtTime(key(idx).time);
}else
  value;

See if this works any better:

P = parent.rotation; 
n = 0; 
if (P.numKeys > 0){ 
  n = P.nearestKey(time).index; 
  if (P.key(n).time > time){ 
    n--; 
  } 
} 
if (n == 0){ 
  t = 0; 
}else{ 
  t = time - P.key(n).time; 
} 
if (n > 0){ 
  v = P.velocityAtTime(P.key(n).time - thisComp.frameDuration/10); 
  amp = 1.0; 
  freq = 1.0; 
  decay = 1.0; 
  w = freq*Math.PI*2;
  P + v*amp*Math.sin(t*w)/Math.exp(decay*t)/w; 
}else{ 
  P; 
}

Did you try:

ImportAsType.COMP_CROPPED_LAYERS;

I’m guessing that you either have an old version of AE or you have File > Project Settings > Expressions > Expression Engine set to Legacy ExtendScript instead of JavaScript.

[Dan Ebberts]

It’s too bad that there aren’t expression-like layer space transform equivalents in the scripting language, because what you really need here is toComp(). What I’d do is have the script temporarily add a point control to the selected layer, add a toComp() expression to it to calculate the layer’s left edge, harvest the result with the script, and delete the point control. The specifics depend on how you have things set up, but in general, that should work.

It looks like when n is 0 (before the first marker) L1 is not defined so this line will fail:

}else{[L1,L1]}

[Dan Ebberts]

Something like this maybe:

dur = 1;
numSegs = 10;
seedRandom(Math.floor(time/dur),true);
segIdx = Math.floor(random(numSegs));
t = time%dur;
segIdx*dur + t 

[Dan Ebberts]

Try it like this:

C = comp("Infinity");
ctrl = C.layer("Head Rotation").effect("x Position")("Slider");
L = C.layer(thisComp.name);
ctrl.valueAtTime(time + L.startTime)

Ah. Try it this way (a trick I learned from Filip):

text.sourceText.value.replace(/[\r\3]/g,"").length
