You should sjust the Contains function to v3.
The things you need to change is getVertextCount() to (getPath().length im
guessing)
And perhaps some of the other methods, but the base should be the same.
/**
* @desc Check if polygon contains point.
* @return boolean
**/
GPolygon.prototype.Contains = function(point) {
var j=0;
var oddNodes = false;
var x = point.lng();
var y = point.lat();
for (var i=0; i < this.getVertexCount(); i++) {
j++;
if (j == this.getVertexCount()) {j = 0;}
if (((this.getVertex(i).lat() < y) && (this.getVertex(j).lat() >= y))
|| ((this.getVertex(j).lat() < y) && (this.getVertex(i).lat() >= y)))
{
if ( this.getVertex(i).lng() + (y - this.getVertex(i).lat())
/ (this.getVertex(j).lat()-this.getVertex(i).lat())
* (this.getVertex(j).lng() - this.getVertex(i).lng())<x ) {
oddNodes = !oddNodes;
}
}
}
return oddNodes;
};
