Try this:


myArray = [3,10,17,20];
included = false;
for (i = 0; i < myArray.length; i += 2){
if (i < myArray.length-1){
if (textIndex >= myArray[i] && textIndex <= myArray[i+1]){
included = true;
break;
}
}
}
included ? 100 : 0

See if this works:

L = thisComp.layer(“Shape Layer 1”);
p = L.content(“Shape 1”).content(“Path 1”).path;
pct = L.content(“Shape 1”).content(“Trim Paths 1”).end/100;
offset = (L.content(“Shape 1”).content(“Trim Paths 1”).offset%360)/360;
L.toComp(p.pointOnPath(pct + offset))

This is a simple example that will track the End point of the Trim Paths:

L = thisComp.layer(“Shape Layer 1”);
p = L.content(“Shape 1”).content(“Path 1”).path;
pct = L.content(“Shape 1”).content(“Trim Paths 1”).end/100;
L.toComp(p.pointOnPath(pct))

You could try this:


p = thisProperty;
idx = p.propertyIndex;
effectIdx = p.propertyGroup(1).propertyIndex;
if (effectIdx != 1)
p.propertyGroup(2)(effectIdx-1)(idx).value
else
value


If the effect above could possibly be a different effect, you may want to add some defensive code to avoid an expression error (or unexpected result) in that case.

Assuming all the layers are contiguous in the layer stack and the parent is on top, something like this might work:

(index – parent.index)*2

There are a lot of ways to do it–this is one:


names = ["Line01","Line02","Line03","Line04","Line05","Line06"];
w = 0;
for (i = 0; i < names.length; i++){
w = Math.max(w,thisComp.layer(names[i]).sourceRectAtTime(time,false).width);
}
w

Assuming you leave Units set to Percentage, something like this should work:

n = text.sourceText.value.length;
t = time – inPoint;
(t/framesToTime(n))*100

Dan

[Dan Ebberts]

This seems to work:

var myComp = app.project.activeItem;
myComp.time += 5*myComp.frameDuration;

I think this will distribute a property between two layers named “Start Layer” and “End Layer” (change the first two lines if your bookend layers have different names):


startLayerName = "Start Layer";
endLayerName = "End Layer";
sStr = 'thisComp.layer("' + startLayerName + '")';
eStr = 'thisComp.layer("' + endLayerName + '")';
sIdx = eval(sStr + '.index');
eIdx = eval(eStr + '.index');
p = thisProperty;
str = ".value";
while(!(p instanceof Layer)){
str = '("' + p.name + '")' + str;
p = p.propertyGroup(1);
}
sVal = eval(sStr + str);
eVal = eval(eStr + str);
linear(index,sIdx,eIdx,sVal,eVal)


It assumes that the layers are contiguous in the layer stack, with “Start Layer” at the top and “End Layer” at the bottom.

I think isValid() does what you want:


var c = app.project.activeItem;
var a = c.layer(1); // "[object AVLayer]"
a.remove();
if (isValid(a)){
alert(a.name);
}else{
// do something else
}
