Did you try filing a trouble ticket on aescripts.com? That seems like the best way to get it resolved.

Actually, that last one isn’t quite right. This should be better:

var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
  myComp = mySelection[i];
  if (! (myComp instanceof CompItem)) continue;
	for (var j = myComp.numLayers; j >1; j--){
		if (myComp.layer(j).locked) continue;
		for (var k = j -1; k > 0; k--){
			if (myComp.layer(k).locked) continue;
			delta = myComp.layer(j).outPoint - myComp.layer(k).inPoint;
			myComp.layer(k).startTime +=delta;
			break;
		}
	}
}

Try this:

var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
  myComp = mySelection[i];
  if (! (myComp instanceof CompItem)) continue;
	for (var j = myComp.numLayers; j >1; j--){
		if (myComp.layer(j).locked) continue;
		for (var k = j -1; k > 0; k--){
			if (myComp.layer(k).locked) continue;
			delta = myComp.layer(j).outPoint - myComp.layer(k).inPoint;
			myComp.layer(k).startTime +=delta;
		}
	}
}

What should it do when it encounters a locked layer?

[Dan Ebberts]

It seems like it should be pretty straightforward. Something like this maybe:

var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
  myComp = mySelection[i];
  if (! (myComp instanceof CompItem)) continue;
	for (var j = myComp.numLayers; j >1; j--){
		delta = myComp.layer(j).outPoint - myComp.layer(j-1).inPoint;
		myComp.layer(j-1).startTime +=delta;
	}
}

Other than a few basic JavaScript manipulations, I think you’ll find everything I used there in the Expressions Language Reference section of AE’s help, specifically in the Properties Attributes and Methods and the Key Attributes and Methods sections.

If these are all instances of the same precomp (i.e. it only shows up as one entity in the project panel), I don’t think there’s a way. They would need to be separate precomps, with unique names.

[Dan Ebberts]

Try this:

p = thisComp.layer("N FX").effect("Checkbox Control")("Checkbox");
t = 0;
if (p.numKeys > 0){
  n = p.nearestKey(time).index;
  if (p.key(n).time > time) n--;
  if (n > 0){
    for (i = 1; i <= n; i++){
      if (p.key(i).value == true){
        if (i < n){
          t += p.key(i+1).time - p.key(i).time;
        }else{
          t += time - p.key(i).time;
        }
      }
    }
  }
}
if (numKeys > 1){
  if (t > key(numKeys).time){
    t = key(1).time + (t - key(numKeys).time)%(key(numKeys).time - key(1).time);
  }
}
valueAtTime(t)

How were you thinking of controlling the hold time?

[Dan Ebberts]

There are some issues, just from a syntax standpoint. This gets rid of the errors, but I don’t if it does what you were hoping for. If not, let us know what it is that you want it to do.

fps = 1/ thisComp.frameDuration;
lt = thisComp.layer("Speed Control").effect("Animation 1")("Menu").value;
if (lt==1) {
    li=1*fps;
    lo=1*fps;
}else if (lt==2) {
    li=2*fps;
    lo=2*fps;
}else {
    li=3*fps;
    lo=3*fps;
}
m1 = 0;
m2 = framesToTime(li);
m3 = framesToTime(lt-lo);
m4 = framesToTime(lt);
k1 = 0;
k2 = framesToTime(30);
k3 = framesToTime(30);
k4 = framesToTime(0);
if(time < m2) {
linear(time, m1, m2, k1, k2);
} else if(time < m3) {
linear(time, m2, m3, k2, k2);
} else {
linear(time, m3, m4, k2, k2);
}
