Trigger Animation by Position
Hello everybody,
first of all, I wasn’t really sure how to put the title so here is a video and afterwards the explanation what I want to achieve:
https://youtu.be/gKhN1CBId2A
I would like the Shape-Layer “particle” start to animate from it’s current yPosition towards a predefined yPosition as soon as the “threshold” rises and pases the “particle”.
I have a basic knowledge of Expressions and tried some things so far, but did not achieve what I have in mind.
Any suggestions are welcome.

Try this ,
Paste this on “particle” -> Transform -> X Position :
Hope this will help
t = time;
if(thisComp.layer("threshold").transform.yPosition.valueAtTime(t) < transform.yPosition.valueAtTime(t)){
loopOut('cycle');
}
else {
key(1);
} -
Here it is the corrected one :
t = time;if(thisComp.layer("threshold").transform.yPosition.valueAtTime(t) < transform.yPosition.valueAtTime(t)){
easeIn(time,inPoint+5,inPoint+9,transform.yPosition.value,500);
}
else {
transform.yPosition;

Here a video how I should look like:
