Getting name for previous composition
Hi, I am trying to create an expression, where I am aligning one composition under another but with dynamically figuring out the name for the one, under which another is aligned. The general idea is to create a bullet list but without a need to constantly rewrite expression to fit compositions names.
<font face=”inherit”>With the help of chatGPT </font>I’ve<font face=”inherit”> </font>managed<font face=”inherit”> to get this far, but </font>I<font face=”inherit”> am getting and </font>error<font face=”inherit”> “T01 Text aN does not exist” and </font>I<font face=”inherit”> can’t figure out, why AE don’t calculate right name. Would </font>appreciate some help. Thanks!
// Get the current composition name
var currentCompName = thisComp.name;
// Extract the composition number
var compNumber = parseInt(currentCompName.split(” “)[2]);
// Calculate the previous composition number
var prevCompNumber = compNumber – 1;
// Format the previous composition name
var prevCompName = “T01 Text ” + (“0” + prevCompNumber).slice(-2);
// Get the text layers from the compositions
var textLayer1 = comp(prevCompName).layer(1);
var textLayer2 = thisComp.layer(1);
// Get the position of the first text layer in the previous composition
var aX = textLayer1.transform.position[0];
var aY = textLayer1.transform.position[1];
// Get the heights of both text layers
var aH = textLayer1.sourceRectAtTime(time).height;
var bH = textLayer2.sourceRectAtTime(time).height;
// Get the spacing adjustment
var adjustments = comp(“T01 Color & Adjustments”).layer(“Color & Adjustments”);
var SpS = adjustments.effect(“Text Lines Spacing”)(“Slider”).value;
// Calculate final x and y positions
var x = aX;
var y = aY + aH / 2 + SpS + bH / 2;
[x, y];
That is with assuming that all the compositions are named sequentially T01 Text 01, 02, 03

Ah, figured it out, the mistake was at first line to use thisComp. The right way would be thisLayer
