follow the leader maintain original position
I have a column of square layers like this :
.
.
.
.
.
.I want the bottom one to fall away and then have the rest follow with a delay so I use this expression on the layers above the bottom layer:
delay = thisComp.layer(“USA”).effect(“delay”)(“Slider”); //number of frames to delayd = 5;
thisComp.layer(index + 1).transform.position.valueAtTime(time – d)of course this puts all the layers at the start position of the bottom layer.
How would I tell the expression to maintain current position or build in a yOffset that would compensate?Thanks

This might answer your question, but it assumes you named the keyframed leader “LEADER”.
You can change that.Xavier
lead = thisComp.layer("LEADER");
refTime = 0; // a time where all layers are lined up
if (time<= refTime) {value;}
else{
delay = Math.abs(lead.index-index)*framesToTime(thisComp.layer("USA").effect("delay")("Slider").value, 1/thisComp.frameDuration);
lead.transform.position.valueAtTime(time-delay) + valueAtTime(refTime) - lead.transform.position.valueAtTime(refTime);

Thank You Very Much!
That worked great.
