Possible to Set a Limit to loopOut Cycles?

[CantinaDan]

I've got a composition with a few layers of precomps. I enabled Time Remapping on each and added this script:
loopOut(loop="cycle",numKeyframes=0)
Works great. I'd love to be able to limit the number of times the animation loops, though. Is that possible?
Thanks much!

Actually, this is better because it lets you define any number of loop areas with comp marker pairs and you don't have to modify the expression:

nLoops = 2;

m = thisComp.marker;
t = time;
if (m.numKeys > 1){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
  if (n > 0 && ! (n%2)){
    t1 = m.key(n-1).time;
    t2 = m.key(n).time;
    loopDur = t2 - t1;
    if (time > t1 && time < t1 + nLoops*loopDur){
      t = t1 + (time - t1)%loopDur;
    }
  }
}
valueAtTime(t)

Last expression is indeed the most practical but I can't set different loop counts for every animation. Every animation in the comp has a fixed duration.

I'm not sure what you mean by the last part.

Check out the screenshot. I want to be able to put multiple different loops made from different set of keyframes. In this example there are two loops that differs in duration. And that's exactly what I want and I would like to be able to have even more loops.

Your screenshot shows a couple of sets of keyframes you want to loop. There may not be enough time between the first set of keyframes and the second set of keyframes for two loops to take place, but there is definitely not enough time between the second set of keyframes and the two keyframes at the end of the timeline for four more loops.

I don't have a suggestion for the expression, but I just wanted to point that out incase another user was confused.

I would also suggest you not use the Drag & drop here button for screenshots. You can copy and paste or drag them to the reply field so you can see them when writing a post, or even use the Toolbar to embed the images.

This is the only thing I can think of. With this version, you can specify the number of loops with the comment of the first marker of the marker pair. If you don't put a number in the marker comment, the expression will use what you have defined for nLoops:

nLoops = 2;

m = thisComp.marker;
t = time;
if (m.numKeys > 1){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
  if (n > 0 && ! (n%2)){
    t1 = m.key(n-1).time;
    t2 = m.key(n).time;
    loopDur = t2 - t1;
    c = m.key(n-1).comment;
    nL = (c != "" && ! isNaN(parseInt(c))) ? parseInt(c) : nLoops;
    if (time > t1 && time < t1 + nL*loopDur){
      t = t1 + (time - t1)%loopDur;
    }
  }
}
