loop, stop, then loop again
Expressions are pretty new to me, and now I’m knee deep in a project that I need an expression for. I have a string of squares attached to a null object. I’m using a LoopOut expression to make it look like the squares are endlessly moving from start to finish. My problem is that I want to stop them for about 20 seconds, then start them back up again. My only idea is to parent them to the null, use a LoopIn expression to get them to move until I need them to stop, then duplicate all the squares, attach them to another null, and use a LoopOut expression to continue on until the end. That would involve a lot of layers, and I know there must be an easier way to do this. I didn’t want to waste anyone’s time with what I’m sure is an easy fix, but I can’t find my answer, and my time is running out. Any help is very very appreciated.

i’m sure there is a clever way to do this with epressions, but the easiest way i know of is to preocomp your animaiton (so all the squares and the null and any other layers that need to be associated with that animation), then use time remapping on the precomp to ‘freeze’ them, then unfreeze them as needed.
here’s a good tutorial on using time remapping to freeze time:

Yeah, after I figured I could stop time then start it again, but I have a day where I’m waiting for an approval, so I figured I’d try to do it cleaner than that. Thanks for the answer, I’ll probably do it your way.
