This should work:

txt = comp("CHANGE TEXT").layer("1 Line Small Text").text.sourceText.value;
cb = comp("CHANGE TEXT").layer("Layout_Selector").effect("Comedy Central")("Checkbox").value;
myFont = cb ? "AmericanTypewriter" : "Helvetica"
style.setFont(myFont).setText(txt)

How does the script know what to delete?

[Dan Ebberts]

I just tried your code and it works for me (the replacement image is still modified by the effect). I’m not sure what could be happening. Maybe a cache or video driver issue–not sure…

Here’s a simple example that gets the comp width from a slider control that has an expression:

var myComp = app.project.activeItem;
var myWidth = myComp.layer(1).property("Effects").property("Slider Control").property("Slider").valueAtTime(0,false);
myComp.width = myWidth;

I’m not sure how you’ve been trying to do it, but an Origin expression like this should work:

L = thisComp.layer("Null 1");
fromComp(L.toComp(L.anchorPoint))

[Dan Ebberts]

Not exactly, but you could do something like this to test for a text layer:

try{
	thisComp.layer(index-1).text.sourceText;
	isText = true;
}catch (e){
	isText = false;
}

and something like this to test for a comp layer:

try{
	isComp = thisComp.layer(index-1).source instanceof Comp;
}catch (e){
	isComp = false;
}

[Dan Ebberts]

Sure. If you use a separator character that’s unlikely to occur otherwise in the text (say, the pipe (|) character, then you could use expressions like this:

thisComp.name.split("|")[0]; // name
thisComp.name.split("|")[1];  // job title
thisComp.name.split("|")[2]; // company

Something like this maybe:

moveDur = .5;
holdDur = 2;
segDur = moveDur+holdDur;
minVal = [0.1*thisComp.width, 0.1*thisComp.height];
maxVal = [0.9*thisComp.width, 0.9*thisComp.height];
seed = Math.floor(time/segDur);
segStart = seed*segDur;
seedRandom(seed,true);
startVal = random(minVal,maxVal);
seedRandom(seed+1,true);
endVal = random(minVal,maxVal);
ease(time,segStart,segStart + moveDur, startVal, endVal);

See if this path expression works for you:

p = thisProperty;
r = sourceRectAtTime(0,false);
pts = p.points();
newPoints = [];
for (i = 0; i < pts.length; i++){
  newPoints.push( [pts[i][0]*thisComp.width/r.width,pts[i][1]*thisComp.height/r.height]);	
}
createPath(newPoints,p.inTangents(),p.outTangents(),p.isClosed())

Time remapping expects time in seconds, not frames. I’d do it like this:

levels = Math.round(thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider"));
if (levels <= 5)
  f = 0
else if (levels <= 10)
  f = 1
else if (levels <= 15)
  f = 2
else
  f = 3;
framesToTime(f);
