hi there,
I'm experimenting a game using google maps api. In the game you control
a plane and you have to destruct the enemy bases with some bullets .
And im having big problems detect the colisions ( intersection of to
poligons ). i use the function *intersects* of the* LatLngBounds *witch
dosent work to well.
after that i use a codesnippet for detecting is 2 poligons intersects but it
works worst ( i dont know if i can use with geographical coordinates)
public function atualizaPos(e:Event)
{
i++;
if (i < percurso.length)
{
marker.setLatLng(percurso[i]);
var limiteNave = new LatLngBounds(new LatLng(mapa.getCentro().x - 0.002 ,
mapa.getCentro().y-0.005),
new LatLng(mapa.getCentro().x + 0.004 , mapa.getCentro().y+0.005));
var limiteBala = new LatLngBounds(percurso[i - 1],percurso[i]);
if (tipo == "daNave")
{
for (var j = 0; j < basses.length; j++)
{
var posBase:LatLng = basses[i];
var limiteBase = new LatLngBounds(new LatLng(posBase.lat()-0.0015 ,
posBase.lng()-0.0015),
new LatLng(posBase.lat()+0.0015 , posBase.lng()+0.0015)
);
if (limiteBala.intersects(limiteBase) )
{
trace("coli Nave - > Base");
}
if( limiteBase.getNorthWest().lat() < limiteBala.getSouthEast().lat() &&
limiteBase.getSouthEast().lat() > limiteBala.getNorthWest().lat() &&
limiteBase.getNorthWest().lng() < limiteBala.getSouthEast().lng() &&
limiteBase.getSouthEast().lng() > limiteBala.getNorthWest().lng() ){
trace("COLI");
}
}
}
}
else
{
mapa.getMapa().removeOverlay(marker);
}
}
}
this is the function the updates the position of the bullet ("bala"), and
where i check if collides it the enemy bases...
Can any one help me ??
