Is there any way to refer to multiple layers within one single expression?
Hey everyone and thank you for reading my thread!
It’s now been like 3 days that I spent desperately trying to figure this out myself and I dug to the bedrock of internet and found nothing working for me…
Here is the situation :I’m making a 100% automated type-on animation in an old computer display look. The animation itself id done and working and now I can put whatever I want in source text and it auto animates and everything is easy to control without a single keyframe involved. Past that I went ambitious and also animated the crushing “beep” noises of type whenever some text is being typed. Everything works beautifully! But now I need to make multiple texts. The problem is that I want to keep the same sound layer to execute the expression for all the text layers. I tried to name all my text layers the same but It only takes the one with the nearest index# into account… I tried to use name.includes() but it is a JS function that is unknown to AE…
There must be a way but I can’t figure it out… I’m sure the solution is right in font of me but is so obvious that I don’t see it.If anyone can help me you’ll get my eternal respect and awe!
Here’s the expression that needs to be solved.
P.S. : the audio level input is 1so i stands for in and o for out. So i = 1*-10 and o =1*-200 (o is to mute the sound basically)
The text layer is called TEXTE because I speak french too hahai = audio.audioLevels*-10
o = audio.audioLevels*-200
if(thisComp.layer("TEXTE").effect("Texte")("Curseur")<1){
o
}
else if(thisComp.layer("TEXTE").effect("Texte")("Curseur")<(thisComp.layer("TEXTE").text.sourceText.length-1)){
i
}
else

You need to have the layers named differently and query ALL the layers within your IF statement using OR (|| in javascipt). So for instance with two layers this would be
... if(thisComp.layer("TEXTE 1").effect("Texte")("Curseur")<1 || thisComp.layer("TEXTE 2").effect("Texte")("Curseur")<1) ...

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. ????????

I don’t know why it wouldn’t. Can you detail your setup more, or take a screenshot showing which layers have which expressions on them?

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-1if((0<a && a<a1) || (0<b && b<b1)) on else off

Most excellent. Happy that it helped. And working out the details yourself is much more educational. ????
