GOOGLE MAPS FLASH API

For each marker, you are going to need a GLatLng position.

So create a GLatLngBounds object, and extend it with each markers position.

Then center and zoom the map on those coordinates.

var latlngbounds = new GLatLngBounds();
 
var posn1 = new GLatLng([latValue], [lngValue]);
latlngbounds.extend( posn1 );
// create the marker here
 
var posn2 = new GLatLng([latValue], [lngValue]);
latlngbounds.extend( posn2 );
// create the marker here
 
var posn3 = new GLatLng([latValue], [lngValue]);
latlngbounds.extend( posn3 );
// create the marker here
 
// Do this after all your markers have been added to the map
map.setCenter( latlngbounds.getCenter( ), map.getBoundsZoomLevel( latlngbounds ) );

Ok I'll give it a shot!
Thanks!

if you take the above code and past it into the root time line of a test FLA it will pull a map with correct markers.

I still can't get the map to center and zoom appropriately.

any ideas?

Another option, if you have a lot of markers to add, calculate the min lat and max lat, min long and max long.  Once you have those, divide all four by 2 or multiply by .5 then add those numbers to the min long and min lat respectively.  This will give you the center latlng at least.

after hours upon hours of testing different things out I'm on to other issues! haha...

I thought it only fair to share my fixed script of this issue for others that may be learning the Google API for flash. below is the AS3 script that zooms and centers appropriately.

thanks to all for the help!

thanks but still didn't fix the problem i posted about.
