Change Layer position by certain value by Marker?
Hi,
is there any expression to change a layer or precomps position with markers? I found something like this:

But it’s not exactly what i am dreaming of and i am not able to change it like i want. ? I want a layer / comp to go up (y position) e.g. for 100px each time if i set a new marker.
Hope you can follow along ? Looking forward to your answer. Thanks alot in advance! ❤

Try this one, it will repeat whatever keyframed animation you have at the beginning of the layer each time a marker is passed, if you need it to offset the animation rather than just repeating it then someone will have to tweak it a little bit.
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time) n–;
}
if (n > 0){
valueAtTime(time-marker.key(n).time);
}else{
valueAtTime(0);
}

Hey thanks,
this seems to be nearly the same as in the tutorial? I need the layer to go up in Y position for a certain number of pixels *each* time i create a marker.
I guess there must be another solution, anybody?

Hey Robert, some info is missing.
1. Should it go up in time (animated) or just move by 100px instantly?
2. Does it need to go down? -
Hey Robert, just paste this in the position expression:
P = transform.position; // layer position
x = marker; // marker
v = 100; // value that you want to move after each marker
n = 0;
if (x.numKeys > 0){
n = x.nearestKey(time).index;
if (x.key(n).time > time) n–;
}
if (n > 0)
d = x.key(n).index
else
d = 0;
m = d*v ; //multiplys marker Index times value
[P[0], P[1]+m]
