question on moving markers

[rlk27]

I inherited a code that was written in V2 and upgrade to V3.  there are marker that are vehicles so, we will have to move the marker with new position info.

 

Questions

 

1. In V2, to reposition the marker, the old one is removed and new marker is created.  i see that setPosition() in Marker object. without removing and createing new one, can we reposition (move) the marker in V3?

 

1. in V2 to bring the marker on the top when clicked,  the old marker  is removed and new marker is created.  in V3, can up update setZIndex() to modify zIndex without having to remove and create new one?
