Can’t get Source Text parameter to execute 2 expressions.
Hello genius people!
Running AE 17.1.4 with JavaScript enabled,
I have two simple expressions on the Source Text parameter.
The first expression retrieves text input from another layer in a separate Comp.
______
comp(“CHANGE TEXT”).layer(“1 Line Small Text”).text.sourceText
______
The second expression changes between two fonts of the text based on a Expressions Checkbox effect.
______
if (comp(“CHANGE TEXT”).layer(“Layout_Selector”).effect(“Comedy Central”)(“Checkbox”) == 1)
(text.sourceText.style.setFont(“AmericanTypewriter”))
else
(text.sourceText.style.setFont(“Helvetica”))
______
Each expression works like a charm when using one or the other.
But when combined – which is my goal – it stops retrieving the text from the other layer.
______
comp(“CHANGE TEXT”).layer(“1 Line Small Text”).text.sourceText
if (comp(“CHANGE TEXT”).layer(“Layout_Selector”).effect(“Comedy Central”)(“Checkbox”) == 1)
(text.sourceText.style.setFont(“AmericanTypewriter”))
else
(text.sourceText.style.setFont(“Helvetica”))
______
Obviously there is some syntax missing that tells the Source Text to do two things
– get text from another layer and check what font to use based on the checkbox.
But my merger expressions skills can’t crack this.
Does anyone have a solution to this or is a current AE cc2020 limitation
cheers!

This should work:
txt = comp("CHANGE TEXT").layer("1 Line Small Text").text.sourceText.value;
cb = comp("CHANGE TEXT").layer("Layout_Selector").effect("Comedy Central")("Checkbox").value;
myFont = cb ? "AmericanTypewriter" : "Helvetica"
style.setFont(myFont).setText(txt)

Haha! Ok, overlord expression master – that worked.
I kind of see what you did – define two variables and then mash them together.
But most is gibberish to me.
What does the “?” do and how does the “:” work to define the two options?
Regardless – super thanx! You guaranteed me at least another months employment.
Dinner and drinks on me next time you hit Stockholm!

That’s the JavaScript ternary conditional operator. It’s a compact alternative to if/else that I like because you can put it on a single line without having to add curly braces.

Compact and elegant.
