Try it this way:

p = thisComp.layer("Shape Layer 1").transform.position;
max = p.value[0];
for (i = 1; i <= p.numKeys; i++){
  max = Math.max(max,p.key(i).value[0]);
}
max

The while loop just starts at the current frame, and goes back in time, frame by frame, until it finds the most recent frame where the text included the target phrase. It then sets variable t to how long ago that occurred.

[Dan Ebberts]

It’s not clear to me exactly what you’re trying to do, but if variable txt is a string, it seems like you should either use parseInt(txt,10) to convert it to a number, or change your conditional tests to look for characters (“0” or “1”) rather than numbers (0 or 1) .

Basically, it’s two nested loops. The outer loop examines each layer in the comp. The inner loop looks at the markers for the layer currently being examined. It starts with the most recent, previous marker, and goes backwards in time until it finds a marker with the tag comment (or runs out of markers). If it finds a marker with the tag, it saves the shortest elapsed time for tag markers found on any layer and uses that value to drive the fade in/out animation.

Maybe like this:

fadeInTime = framesToTime(thisComp.layer("CONTROL_politicalParties").effect("FADE IN/OUT")("Slider"));
fadeOutTime = framesToTime(thisComp.layer("CONTROL_politicalParties").effect("FADE IN/OUT")("Slider"));
delay = framesToTime(thisComp.layer("CONTROL_politicalParties").effect("DURATION")("Slider"));
wig = wiggle(thisComp.layer("CONTROL_politicalParties").effect("WIGGLES PER SEC")("Slider"),thisComp.layer("CONTROL_politicalParties").effect("amp_SPD")("Slider"));

tag = "trig";
t = 999999;
for (i = 1; i <= thisComp.numLayers; i++){
  s = thisComp.layer(i).marker;
  if (s.numKeys > 0){
    n = s.nearestKey(time).index;
    if (time < s.key(n).time) n--;
    for (j = n; j > 0; j--){
      if (s.key(j).comment == tag){
        t = Math.min(t,time - s.key(j).time);
        break;
      }
    }
  }
}
if (t < fadeInTime)
  linear(t,0,fadeInTime,0,wig)
else
  linear(t,fadeInTime,fadeInTime+delay+fadeOutTime,wig,value);

>Maybe you will tell me: why don’t you use that script that you already have?

I’m sorry–you lost me. What script are you talking about?

[Dan Ebberts]

It seems like that would be a bit of a bookkeeping headache. I think you’d have to keep track of the previous layer selection set, then on the next entry, check to see if selLayers is exactly the same as it was last time, and if so, bump a counter that you would then use as a multiplier for i*offset. Might be kind of confusing for the user too (unless it’s just you).

[Dan Ebberts]

Ah, OK. The loop should probably be like this:

var tStart = selLayers[0].inPoint;
for (var i = 0; i < selLayers.length; i++)
{
  selLayers[i].startTime -= selLayers[i].inPoint - tStart - i*offset;
}

[Dan Ebberts]

Try changing this:

selLayers[i].startTime = (selLayers[i].inPoint = selLayers[i].startTime) + i * offset;

to this:

selLayers[i].startTime -= selLayers[i].inPoint - i*offset;

[Dan Ebberts]

Like this, I think:

a =16;
b = 20;
c = 18;
A = radiansToDegrees(Math.acos((b*b + c*c - a*a)/(2*b*c)));
B = radiansToDegrees(Math.acos((a*a + c*c - b*b)/(2*a*c)));
C = radiansToDegrees(Math.acos((a*a + b*b - c*c)/(2*a*b)));
