Change Size of Shape Layer based on Text Layer

Hey guys,

I'm looking for an expression (preferably) to change the width of a plain ol' black rectangular box that's sitting beneath a layer of text. The text layer is going to change length, and I therefore need the black box to adjust with the text and change length accordingly. I'm sure there's a simple way to do this, but I've been fighting a cold all week and my brain is a little fried.

Any suggestions?

There's a (relatively new) expression function that does exactly this: "sourceRectAtTime"

Hi Kyle,

Thanks! Your link was helpful. This is what I ended up with:

theTextLayer = thisComp.layer("TEXT");

p = 50;

box = theTextLayer.sourceRectAtTime(time);

x = box.width + (p*2);

y = 150;

[x,y]
