I have 4 layers, expression pointed to the X rotation of a Null. I want them to follow the X rotation to flip up, but I'd like them to ripple...so I need to have them follow the rotation of the Null, with a seperation of a period of time.
thisComp.layer("Rotate up products").transform.xRotation
I have VERY LITTLE experience with expressions, but I need to do this several times, so I'd like to reuse this function.
This page gives you your answer. Reading the whole thing (and actually, all of the resources at that site) would be very helpful to anyone trying to learn expressions. However, what you want, specifically, is in the section called An Interesting Variation.
