Animate object along animated path
on Oct 12, 2019 at 12:33:49 am

Hi there,

I've created a path that has vertices animated to follow an underlying map. The map is a slow zoom in on Google Earth looking at the ground at about 45 degrees, so each vertex of the path is keyframed to follow a point on the map to allow for perspective shift during the zoom. This path will be an animated route on the map.

I'm now trying to make a glowing dot follow the path as it's revealed - is there a way to make an object follow a path that is itself animated with keyframes? The only tutorials I've found show how to paste a static path into an object's position attribute, then animate the object along that fixed path, but this method doesn't allow for a path with animated vertices.

Thanks for any help!

Assuming that you're using Trim Paths to set the end point of your path, an expression like this (for the position of your dot) should track an animated path:

L = thisComp.layer("Shape Layer 1");
path = L.content("Shape 1").content("Path 1").path;
pct = L.content("Shape 1").content("Trim Paths 1").end;
