move marker along a polyline - Google Maps API V2 | Google Groupes
Animation of polylines - Google Maps API For Flash | Google Groupes I may have over played this demo on the forums already, but I think you could still benefit from it... possibly. I'm not sure what kind of animation you're looking for on the polyline, but I would imagine something like look-up directions from here to there, then show the path drawn incrementally like Indiana Jones style. What I think you'd need to do to have that kind of control is have it calculate the directions then use the array of points along the directions to draw them one at a time with some sort of delay between the drawing of each segment.
