Reeplace content of a layer
Hello ,
I am new to After Effects scripting and I have been playing with the language. This is the visual setup of the project I have :
Now , as a test , I have the following script :
app.project.activeItem.layers[1].sourceText.setValue('Hello World')If I run this little script, I am able to change the text of my layer 1 from This is a test to ‘Hello World’.
My question is , how can I do this operation when I am not active at the layer?
As far as I know , if we run :
var activeItemid = app.project.activeItem.id;
alert(activeItemid)I am able to get the id of the current item :
But , If I try :
app.project.item(activeItemid).layers[2].sourceText.setValue('This is just a test')It does not work.
Can you explain me how does this work?
Thank you.

You can’t access to comp by name directly, you must do it by index or by writing a findComp function like this:
function findComp(compName){
var proj = app.project;for(var i = 1; i <= proj.numItems; i++){
var comp = proj.item(i);
if(!(comp instanceof CompItem) || comp.name != compName){
continue;
}
else {
return comp;
}
}
}
Other problem is that you only have one layer on your comp, so you can`t acces layer[2]. In layers case, you can acces layer by name. You can write this bellow findComp function:var myComp = findComp("Text 01");
myComp.layer("Layer 1").text.sourceText.setValue( "Your value"); -
This is exactly what I was looking for.
proj.item(i);was the key , and that function you provided is pretty useful. Thank you!
