Use Source Text as expression
Hi everyone,
I have a text layer with a slider. In the source Text, I wrote “wiggle(5,50)” (without the quotation mark).
I’d like the Slider property to use this text as an expression. How? I’ve searched the internet for 1 hour and I can’t find an answer!The code below obviously doesn’t work. AE understands it as a Text value, not a property or expression.
Have a nice day!
thisLayer.text.sourceText;

Try it this way:
eval(text.sourceText)

Hi Dan,
On AE CC2017 it is not working, same error message.

Remi, as a workaround, you could instead define a wiggle in the slider, and just control numeric values by assigning other slider values (for speed and influence).
I tried Dan’s example in CC2019 and it also does not work though.

Thank you for the workaround Tomas but I am trying to create a project to test expression calculation speed and your solution won’t work :
I wanted to have a text layer where I can write the expression I want to test and then have the properties of 50 layers linked to this Source text. This way I could easily change/improve the expression on just a single text layer and see how it affects the preview time on a lot of layers.
This is the easiest setup I came up with but maybe it’s not possible to convert text values into property. -
Would love to see the results if you come up to a solution! In the meanwhile, if some idea pops into my head I will let you know. Are you using CC2017 only or higher versions are applicable too?

Ah, OK–slight change:
eval(text.sourceText.value)

If the results are conclusive I will share the project file Tomas, I’ll let you know! For now I’m working on AE CC2017 to maximize its compatibility.

It works! Thank you Dan!
