I figured out the issue! The line of code that reads “if ( frameRestart &lt;= delay)” had somehow replaced “<” with “&lt;” so replacing the character ended up doing the trick 🙂

What I’m aiming to accomplish is automated rotation overshoot for a 3D layer when it is parented to something that rotates and changes position, so this code has given me something to start with. The examples that you’ve posted on CC over the years and detailed descriptions on motionscript.com have been SUPER helpful as always, but if there are any classic Dan solutions to this problem that I haven’t been able to unearth, I’d love to know!

I’ve been looking for a solution to a similar problem and am so glad I discovered this post! I’m curious if you might be able to upload a working AE file that uses your approach as an example? I’ve tried copy and pasting your posted expressions into both position and anchor points, but I get met with some errors am finding difficult to debug. An expression that provides lag/overshoot without relying on keyframes is exactly what I’m after, and if you’ve found something that works, I’d be extremely grateful for any help you can give!

Thanks for the suggestion!

I found a thread from 2009 which is actually similar to my thinking, but they didn’t figure it out back then, and I was hoping there’d be a solution by now:

I know in the Obsolete menu there’s an effect called ‘Path Text’ which has some of the parenting options I’m looking for (allows you parent the ends of a curve as well as control the tangent handles)… only problem is that it chugs when adjusting in real time, and doesn’t allow for multiple curves (unless you duplicate the effect and parent the handles to each other)

Still open to any other ideas that might be floating around out there! Thanks!

PS: is there a list of specific properties that can be accessed for Text attributes while using expressions? I was hoping I might be able to use a ‘toComp’ type of result to parent values to

One method would be to use an expression to link the Bulge Center value to the Null position. In the Bulge effect controls, hold down the Command button on your keyboard and click on the stopwatch. You’ll see the number turn red, but you’ll also see that there’s now some text that appears in your timeline… something like ‘effect(“Bulge”)(3)’. With that text highlighted, click the pick whip button (the little spiral to the left of the text) and click-drag that to the position property of your null. It should bring up something like:

thisComp.layer(“Null 1”).transform.position;

but just make sure that the “Null 1” is the correct name of the object that has the motion data on it. That should link the position data from the tracking to the bulge location.

Hope this helps!
