Sir, Kalleheikki Kannisto,
I OWE you a billon thanks !!!! I tried on a test comp to express the opacity of a solid referring to the y position of 2 others to reproduce a condition similar to the one with the sound… and it worked just fine.
So i thought really hard and figured out that there were 2 problems… 1st my expression was way too messy and confusing, 2nd the two conditions (if() else if() else) worked fine for one layer but when it ran with 2 layers there was a contradiction (the argument was only true for one at a time).
So I cleared it all up and simplified it as follow and IT WORKED JUST AS EXPECTED!
You can’t imagine how glad and thankful I am! It really helped me out because you sent me thinking in the right direction ????
Guys, this man deserves a cookie, and a tight hug! ????

on = timeToFrames(time)%2*effect("Tonalité")("Niveau")
off = 0
a = thisComp.layer("TEXTE").effect("Texte")("Curseur")
a1 = thisComp.layer("TEXTE").text.sourceText.length-1
b = thisComp.layer("TEXTE 1").effect("Texte")("Curseur")
b1 = thisComp.layer("TEXTE 1").text.sourceText.length-1

if((0<a && a<a1) || (0<b && b<b1)) on else off

Thanks Kalleheikki Kannisto for your quick answer, but I already tried this and it doesn’t work… There’s no error but it executes only for one of the two layers. ????????

You could also trick it like that if you want it to go by itself by copying this in the text source (s is the speed, knowing that x1 speed is 100/sec) :

s = 1
if(time<1) 0 else Math.floor(time*s)+"00"

Hey Mathias,

I’m figuring that out but I need to understand more clearly what you want to achieve. If I got it right, you want to have control over the absolute size of the balls independently of the spacing right?
