I'm not sure what you're looking for exactly, but maybe something like this: target = thisComp.layer("Color_gradient"); s = target.sampleImage(target.fromWorld(toWorld(anchorPoint)), [0.5,0.5], true, time); Math.round(s[0]*255) + ", " + Math.round(s[1]*255) + ", " + Mat...

Play with this:

freq = 1;
midVal = 20;
range = 10;

midVal + range*Math.sin(time*freq*Math.PI*2)

I'm afraid you're out of luck. You can poke around a little with source text expressions like this:

prop = text;
prop.numProperties;

or,

prop = text;
prop(3)(1).name

But I don't think you'll find anything helpful. Different story with scripting though...

Dan

I don't think there's a way to do that. Scripting doesn't have much access to AE's UI. I think the most you could do would be to issue the menu command "Show Rulers", but that doesn't help much.

Dan

Based on my limited sample size, it appears that maybe missing effects show up in the list with the category blank. Would that help in your case?

Dan

That's a little trickier, but I think this works: var myComps = app.project.selection; var myComp; for (var i = 0; i < myComps.length; i++){ myComp = myComps[i]; if (myComp instanceof CompItem){ setLayers(myComp); } } function setLayers(theComp){ for (var i = 1; i <= theComp.numLayers; i++){ try{ th...

I think this will work: var myComps = app.project.selection; var myComp; for (var i = 0; i < myComps.length; i++){ myComp = myComps[i]; if (! (myComp instanceof CompItem)) continue; for (var j = 1; j <= myComp.numLayers; j++){ try{ myComp.layer(j).quality = LayerQuality.DRAFT; }catch(err){ } } } Dan

Scripting doesn't have much control over the AE UI, and I don't know of any way to do what you're asking for. It's possible there's some kind of hack for it, but I'm not aware of one.

Dan

Something like this should work:

txt = thisComp.layer("Text Layer").text.sourceText.value;
n = parseFloat(txt);
if (isNaN(n)) value else n;


Dan

Expressions can't access metadata, but scripting can. Adobe's JavaScript Tools Guide has a chapter on it. It's not simple, but there are probably some good examples around.

Dan

I should point out that the latest version of AE CC 2014.2 (build 13.2.0.49) does support sourceRectAtTime() for expressions.

Dan

What info are you after exactly?

Something like this should work: var myComp = app.project.activeItem; if (myComp && (myComp instanceof CompItem)){ var myProps = myComp.selectedProperties; if (myProps.length > 0){ for (var i = 0; i < myProps.length; i++){ if (myProps[i].canVaryOverTime){ myProps[i].addKey(myComp.time); } } ...

This should work too:

if (myComp.layers[y] instanceof TextLayer)


Dan

I'm not sure exactly what you're after, but I ran a quick test, and this slider expression always gives me 0.00 no matter what color I choose for the Fill effect: c = effect("Fill")("Color"); L1 = rgbToHsl(c)[2]; L2 = (Math.max(c[0],c[1],c[2]) + Math.min(c[0],c[1],c[2]))/2 L2 - L...
