Problem with expression controls
Hi!
I’m having a problem using a Slider control. What I’m trying to to is to have a textlayer read portions of another textlayer. Here’s my expression on the textlayer:
i=effect(“Slider Control”)(“Slider”);
source=thisComp.layer(“Textsource”).text.sourceText.substring(0,i);
Let’s say I set my slider control to a value of 10, nothing happens… But if I alter the expression to look like this
i=10;
source=thisComp.layer(“Tekstkilde”).text.sourceText.substring(0,i);it works…
What am I missing?
Cheers!

Try this:
i=effect(“Slider Control”)(“Slider”).value;
source=thisComp.layer(“Textsource”).text.sourceText.substring(0,i);Dan

Thank you! That worked 🙂

Is it possible to set the sourceText to the value of a variable that you create for a function that is in another layer.
Basically, I am trying to create a text field that allows me to effectively trace values of variables much as you might in Adobe Flash actionscript.
thanks!

nope,
you can only reference the actual value or outcome of an expression.
So you would need to copy the entire expression to the textlayer, and make sure that variable is the last thing that gets evaluated.
