You can just borrow a convenient property, like rotation, wiggle that, then subtract out its value:

parseFloat(text.sourceText)+ rotation.wiggle(1,100) – rotation

Yes, for lights (or cameras) you’d want to do it like this:

L = thisComp.layer(“Light 1”);
L.toComp([0,0,0])

Like this:

L = thisComp.layer(“Null 3”);
L.toComp(L.anchorPoint)

The only thing I can think of would be to turn off auto orient and use this rotation expression instead:


v = position.velocity;
if (length(v) == 0){
t = time - thisComp.frameDuration;
while (t > inPoint){
v = position.velocityAtTime(t);
if (length(v) != 0) break;
t -= thisComp.frameDuration;
}
}
radiansToDegrees(Math.atan2(v[1],v[0]))

Something like this should be close:


amp = 100;
freq = 1;
maxRun = 5;
minRun = 1;
maxHold = 5;
minHold = 1;
tPrev = t = inPoint;
seedRandom(index,true);
accumPrev = accum = curRun = 0;
while (t <= time){
curRun = random(minRun,maxRun);
curHold = random(minHold,maxHold);
tPrev = t
accumPrev = accum
accum += curRun
t+= curRun + curHold;
}
if (time - tPrev < curRun)
wiggle(freq,amp,1,0.5,accumPrev + time - tPrev)
else
wiggle(freq,amp,1,0.5,accumPrev + curRun);

You would generally use else if to combine them. I’m not sure if this is the logic you had in mind, but this would be one way to combine them:


if (thisComp.layer("Percentage 2").content("Trim Paths 1").end==0)
0
else if (thisComp.layer("EXTRACT PIECE").effect("3 Extract Z")("Slider")==1-59)
0
else
100;

It’s hard to say without seeing your setup exactly, but you should be able to use the index provided by the dropdown to select the correct layer in the precomp and then use sourceRectAtTime() to get the width of that layer:

idx = thisComp.layer(“Controls”).effect(“Logo”)(“Menu”).value;
w = comp(“precomp”).layer(idx).sourceRectAtTime(time,false).width

I think it would be like this:


dur = effect("Duration")("Slider")*thisComp.frameDuration;
holdTime = effect("Hold Time")("Slider")*thisComp.frameDuration;
t1 = inPoint;
t2 = t1 + holdTime;
t3 = t2+dur;
t4 = t3+holdTime;
if (time < t2)
t = linear(time,t1,t2,key(1).time,key(2).time)
else if (time

I think it would be something like this:

dur = effect(“Duration”)(“Slider”)*thisComp.frameDuration;
holdTime = effect(“Hold Time”)(“Slider”)*thisComp.frameDuration;
t1 = inPoint + dur;
t2 = t1 + holdTime;
t = linear(time,t1,t2,key(1).time,key(2).time);
valueAtTime(t)

Maybe like this:

delay = 5; //number of frames to delay
d = delay*thisComp.frameDuration*(index – 1);
p = thisComp.layer(1).position.valueAtTime(time – d);
[value[0],p[1]]
