Loading the Game Scene - WebGL Game Development - page 96

Open the 03-Loading-Scene.html file in your favorite editor. If you observe the
scene, you will see that there are four buildings, six street lamps, and two railings.
Hence, we added the cloneObjects function that clones the objects and adds
them to the scene. The cloneObjects function invokes the function clone of the
SceneObject's class, which invokes the clone function of the Geometry class. The
following is the code snippet from the 03-Loading-Scene.html file:
function start() {
........................................
addStageObject("model/obj/terrain.json",
[0.0,0.0,0.0],0.00,0.0,0.0);
addStageObject("model/obj/building.json",
[55.0,0.0,170],0.0,0.0,0.0);
addStageObject("model/obj/giantPillar.json",
[-60.0,0.0,-200],0.0,0.0,0.0);
addStageObject("model/obj/pillarBroken.json",
[10.0,0.0,-200.00],0.0,0.0,0.0);
addStageObject("model/obj/streetlamp.json",
[20.0,0.0,200.00],0.0,0.0,0.0);
addStageObject("model/obj/cityLine.json",
[12.0,0.0,-335.0],0,3.14,0.0);
addStageObject("model/obj/railing.json",
[0.0,5.0,200.0],0.0,0.0,0.0);
addStageObject("model/obj/dump.json",
[-40.0,0.0,-30.0],0.0,0.0,0.0);
initScene();
}
function addStageObject(url,location,rotationX,
rotationY,rotationZ){
$.getJSON(url,function(data){
.........................................
cloneObjects(stageObject)
...........................
});
}
function cloneObjects(stageObject){){
if(stageObject.name=="building"){
var building1=stageObject.clone();
..................
building1.location=[-85.0,0.0,170.0];
..........
stage.addModel(building1);
.....
}
