Animate object along animated path
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;
L.toWorld(path.pointOnPath(pct/100,time))Dan

Ah this worked perfectly, thank you so much!

I’m getting a “syntax error” on line 1 (see screenshot). Can you help?
Thanks!

You probably just need to swap out the curly quotes for straight quotes:
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;
L.toWorld(path.pointOnPath(pct/100,time))

That fixed it! Thanks!
