Actually, you can leave all that layer name/index stuff out:


startScale = [0,0];
endScale = [100,100];

if(time < (inPoint+outPoint)/2)
ease(time,inPoint,inPoint+0.2,startScale,endScale)
else
ease(time,outPoint-0.2,outPoint,endScale,startScale);

Try this:

c1 = [1,0,0,1]; // red
c2 = [1,.5,0,1]; // orange
c3 = [1,1,0,1]; // yellow
c4 = [0,1,0,1]; // green
c5 = [0,1,1,1]; // cyan
c6 = [0,0,1,1]; // blue
colors = [c1,c2,c3,c4,c5,c6,c5,c4,c3,c2];
secondsPerColor = 1;
idx = Math.floor((time – inPoint)/secondsPerColor)%colors.length;
colors[idx]

Something like this should work:

seedRandom(Math.floor(time), timeless = true);
c1=thisComp.layer(“Null 1”).effect(“Color Control”)(“Color”);
c2=thisComp.layer(“Null 1”).effect(“Color Control 2”)(“Color”);
c3=thisComp.layer(“Null 1”).effect(“Color Control 3”)(“Color”);
c4=thisComp.layer(“Null 1”).effect(“Color Control 4”)(“Color”);
c5=thisComp.layer(“Null 1”).effect(“Color Control 5”)(“Color”);
c6=thisComp.layer(“Null 1”).effect(“Color Control 6”)(“Color”);
idx = Math.floor(random(6))+1;
eval(“c” + idx)

That’s pretty much it. They way you had it, the expression in layer n requires the expression engine to recalculate the expression in layer n-1, which requires recalculation of layer n-2, and so on, increasing geometrically with the number of layers. It can bog things down in a hurry.

I think you’ll get better performance if you avoid a cascading expression (where each expression depends on the result from the expression in the previous layer) and just use a straight ahead calculation based on layer index, like this (not tested):
thisComp.layer(2).transform.xPosition + (index-2)*thisComp.layer(“Control”).effect(“Distance”)(“Slider”)

This should be closer:

txt = thisComp.layer(“Text”).text.sourceText;
parseFloat(txt) < 50 ? [0,1,0,1] : [1,0,0,1]

Dan

[Dan Ebberts]

I think this does what you’re asking for. I’m not sure it’s what you meant though.

txt = thisComp.layer(“Text”).text.sourceText;
txt == “50%” ? [0,1,0,1] : [1,0,0,1]

Try it like this:


sVal = thisComp.layer("Adjustment Layer 2").effect("Slider Control")("Slider");
if (time < key(2).time)
x = easeOut(time,key(1).time,key(2).time,key(1).value[0],sVal)
else if (time < key(3).time)
x = linear(time,key(2).time,key(3).time,sVal,sVal-11)
else
x = linear(time,key(3).time,key(4).time,sVal-11,sVal);
[x,value[1]]

[Dan Ebberts]

Sure. It might look something like this:

pct = comp(“Controls”).layer(“Controls”).effect(“Percent”)(“Slider”);
seedRandom(index,true);
random() < pct/100? 100 : 0

You could add a minDelay variable, like this:

minDelay = 3; // shapes wait at least 3 seconds to turn on
maxDelay = 5; // all shapes turn on within 5 seconds
seedRandom(index,true);
myDelay = random(minDelay,maxDelay);
time – inPoint < myDelay ? 0 : 100

then adjust the first two lines to suit.
