Wiggle Flicker expression
Trying to create an expression that will trigger when a marker is reached for 12 frames from a marker’s time. I couldn’t find any resource online stating how to make an expression last for a specific duration. Drove me crazy. I tried writing it myself, but I’m not getting anywhere. Any suggestions?
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
}if (n == 0){
value;
} else {
if ((marker.key(n).time) < (marker.key(n).time+12)){
wiggle(8,100);
}else{
value;
}
} -

Hold the phone. I got it.
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
}if (n == 0){
value;
} else {
if (time < (marker.key(n).time+1)){
wiggle (5,100);
}else{
value;
}
}However I’m going by timecode, and I’d like to work in frames. I know there’s a timeToFrames, but how do I work that in to this? Do I need to set time converted to frames as a variable? How do I use that with marker.key?

I haven’t tested it, but this should work:
if (timeToFrames(time) < (timeToFrames(marker.key(n).time)+1))

Yup, thats it. Thank you Dan.
Final flicker code:
//triggers a flicker at every layer marker lasting 12framesn = 0;
duration = 12; //# of frames from marker
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
}if (n == 0){
value;
} else {
if (timeToFrames(time) < (timeToFrames(marker.key(n).time)+duration)){
wiggle (10,90);
}else{
value;
}
}
