Question

sourceRectAtTime on text layer crashes.

I have been getting many crashes using this expression and would love to figure out why. The expression measures the lenght of the text and if it exceeds a certain amount, splits the text into two and adds a line break in the middle. It seems to work fine but has been causin insta-crashes on my whenever I try to change anything on the text layer - font size, add a position text animator and start scrubbing, etc. Thanks in advance for any help.

I included all the different crashes that I received in the past hour while working on this project. Using OSX 11.3.1 and AE 18.2.0

The expression is:

maxWidth = 880;
layerWidth = thisLayer.sourceRectAtTime(time,false).width;
if(layerWidth > maxWidth){
layerText = value
words = layerText.split(" ") mid = Math.round(words.length / 2)
value = words.slice(0,mid).join(" ") + "\r" + words.slice(mid).join(" ") }
else{ value }

"value" is a reserved keyword revferencing the property value in AE. You cannot arbitrarily use it as a variable name in your own code. And you may also want to help matters along by actually writing your code line by line and using semicolons. contrary to what self-proclaimed "web dev geniuses" on YouTube and elsewhere state, these things aren't superfluous, especially since AE is not a web browser and has not many safeguards for bad code.

Thanks for the suggestion Mylenium. I've updated the code to below but still crashing just the same. Any ideas on what I can change in the expression to make it not crash? Or another way to do the same thing?

maxWidth = 880;
layerWidth = thisLayer.sourceRectAtTime(time,false).width;
if(layerWidth > maxWidth){ layerText = thisLayer.text.sourceText;
words = layerText.split(" ");
mid = Math.round(words.length / 2);
twoLines = words.slice(0,mid).join(" ") + "\r" + words.slice(mid).join(" ");
}else{ thisLayer.text.sourceText; }
