Display array in text source
Hi,
I don’t know if it’s possible, but I want to display selected array properties in multiples text source.
The idea is to paste mutiples numbers in an array, for exemple : [75, 60, 40]
And in 3 text layers, select which one will be displayed.
I could do it manually but, I need to do it for 20 text layers, so I wonder if it can be automatic.
Thanks

I’m not sure at all if this is what you’re asking, but if you want a layer’s visibility to be driven by an array, you could use an opacity expression like this:
array = [75, 60, 40];
array.indexOf(index) > -1 ? 100 : 0
and then only layers 40, 60, and 75 would be visible. (Note that this requires the JavaScript expression engine).
If that’s not what you’re after, please provide more detail.

Thanks Dan,
I’ll be more specific about my project.
I’m working on a ranking system, so I wonder if it’s possible to write each points of each teams in a text source with an array, and pick the array value we want to display to text layer one by one ?

Ah, OK. Each of your points layers would need an expression something like this:
txt = thisComp.layer("text with all data").text.sourceText;
myIdx = parseInt(name.split("_")[1],10)-1;
eval(txt)[myIdx]
This assumes that the points layer’s name is in the format you’ve shown: “team.points_n”, where “n” minus 1 becomes the index into the array.

Thanks for your reply.
I pasted the expression, and try few things but nothing worked.
my layer “team.points_1” shows nothing.
Also I’m starting to learn Ae expression so I don’t understand “parseInt” and “eval”… 😅

Hard to say what’s wrong without seeing your project. The expression did work for me when I set it up though.
