If last line empty – use previouse one
Hey guys. I need some help figuring out how write it.
I have a bullet list with 9 lines of text.
What i am trying to write is an expression to find last line which is empty based on .height and use previous that is not empty.I have an expression to determine the longest line.
var out_width = 0;
for (i = 1; i <= 9; i++) { var elem = comp("T01 Text 0" + i).layer(1); var w = elem.sourceRectAtTime(2).width; if (out_width < w) out_width = w; } Found out similar question here https://stackoverflow.com/questions/33268863/find-last-matching-object-in-array-of-objectsBut can’t figure out how to rework one i have to fit what i need.
Text lines naming goes like T01 Text 01, T01 Text 02 etc.
Can’t use number of the layer, cause between lines of text can be other objects.Thank you.

I guess it would look something like this:
var maxNonEmpty = 0;
for (i = 1; i <= 9; i++) {
var elem = comp("T01 Text 0" + i).layer(1);
var w = elem.sourceRectAtTime(2).width;
if (w > 0){
maxNonEmpty = i;
}
}
maxNonEmpty

Dan, one more question.
This whole thing works perfectly with file names T01 Text 01 – T01 Text 09. When i want to add more text lines with names T01 Text 10 and etc. it results with an error, cause there is no comps like T01 Text 010. How should i change the conditions so i can use more lines of text with similar naming?
Thanks!

I haven’t tested this, so watch for typos, but something like this should work up to 99:
function pad(n){
return (n < 10 ? "0" : "") + n;
}
var maxNonEmpty = 0;
for (i = 1; i <= 15; i++) {
var elem = comp("T01 Text " + pad(i)).layer(1);
var w = elem.sourceRectAtTime(2).width;
if (w > 0){
maxNonEmpty = i;
}
}
maxNonEmpty
