Animation Challenge

I have a field of symbols of varying opacities and sizes (over 100). I need to animate all of them moving up and out of view at different speeds. I used null objects and animated them going from below the stage to above the stage and added a loopOut(type="continue") expression to the position property.

The problem is that the symbols leave the stage. Ideally, the symbols should cycle back from the bottom and to the top. I'm not sure how to get that to work. loopOut(type="cycle") does that, but the symbols appear back where they started.

Essentially, it should just be a continuous loop for every symbol. I was thinking a particle effect might help, but there are 2 symbols and they vary a bit. Any suggestions?

Correct answer Airweb_AE

Maybe something like this:

seedRandom(index, true);
dur = Math.random() * 3 + 1;
seedRandom(Math.floor(time / dur), true)
x = Math.random() * thisComp.width;
y = linear(time % dur, 0, dur, thisComp.height + sourceRectAtTime().height / 2, -sourceRectAtTime().height / 2);
[x, y]
