Incremental Animation based on Layers or Markers
Hello friends,
I’m wondering if there’s a way to incrementally repeat/offset a set of keyframe’s animation, similar to how loopOut(“offset”) works, but to only trigger at every marker? Or in an ideal world, though may be a stretch, to trigger at the inPoint of any layer with a defined prefix.
eg. ‘Shape Layer 1’ has two position keyframes moving it up 20px. I’d like for it to automatically move up an extra 20px (with the same ease) every time either there’s a marker, or if possible, at the inPoint of layers L_01, L_02 etc
Hope this makes sense,
Thanks in advance!

I think this will work for your layer in point scenario:
n = 0;
trig = 0;
for (i = 1; i <= thisComp.numLayers; i++){
if (i == index) continue;
if (thisComp.layer(i).name.indexOf("L_") == 0){
if (time > thisComp.layer(i).inPoint){
n++;
trig = Math.max(trig,thisComp.layer(i).inPoint);
}
}
}
if (n > 0){
d = key(numKeys).value - key(1).value;
key(numKeys).value + (n-1)*d + valueAtTime(key(1).time + (time - trig)) - key(1).value
}else{
value;

You’re sick, Dan. That works, thank you!!
Is there a way to have the original keyframes have no affect, until the first ‘L_’ in point? Almost like that triggers the first increment of animation?
No worries if not, this works better than I imagined it would.
Thanks,

I think that would be like this:
n = 0;
trig = 0;
for (i = 1; i <= thisComp.numLayers; i++){
if (i == index) continue;
if (thisComp.layer(i).name.indexOf("L_") == 0){
if (time > thisComp.layer(i).inPoint){
n++;
trig = Math.max(trig,thisComp.layer(i).inPoint);
}
}
}
if (n > 0){
d = key(numKeys).value - key(1).value;
key(numKeys).value + (n-2)*d + valueAtTime(key(1).time + (time - trig)) - key(1).value
}else{
key(1).value;
} -
That’s done it. Thanks Dan!

Thanks for solving this Dan!
