Google Maps API Polygon with "Hole" In Center
Inserting a polygon inside another polygon is supposed to make a "hole" in the center (see the Google maps Pentagon example). However, my program keeps failing to make a hole and instead makes two layers of polygon lines insead.

Someone said changing the coordinate order fixed their problem so I selected exactly the coordinates of the bermuda triangle as given by Google in their example, however, it had the same problem I encountered before. The relevant code is below:
var everythingElse = [
new google.maps.LatLng(25.774252, -82.190262),
new google.maps.LatLng(17.466465, -65.118292),
new google.maps.LatLng(34.321384, -63.75737),
new google.maps.LatLng(25.774252, -82.190262)
];
var circleOverlay = [
new google.maps.LatLng(25.774252, -80.190262),
new google.maps.LatLng(18.466465, -66.118292),
new google.maps.LatLng(32.321384, -64.75737),
new google.maps.LatLng(25.774252, -80.190262)
];
PropertySearch.tintPolygon = new google.maps.Polygon({
paths: [ everythingElse, circleOverlay ],
strokeColor: "#000000",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#000000",
fillOpacity: 0.5
});
PropertySearch.tintPolygon.setMap(PropertySearch.map);
It really is a matter of direction of indices in your polygons, while one is clockwise other should be counter-clockwise. Change your second array to:
var circleOverlay = [
new google.maps.LatLng(25.774252, -80.190262),
new google.maps.LatLng(32.321384, -64.75737), //second and third coordinates
new google.maps.LatLng(18.466465, -66.118292), //are swapped compared to your original
new google.maps.LatLng(25.774252, -80.190262)
];
and it will display a nice hole in your triangle
