also realized you need to load up your mesh so
private var _mesh:Mesh;
public function away3d():void
{
createOBJ(); // make a function to create your object
}
private function createOBJ():void
{
ResourceManager.instance.addEventListener(ResourceEvent.RESOURCE_RETRIEVED,
onResourceRetrieved);
container =
ObjectContainer3D(ResourceManager.instance.parseData(new OBJ(),
"cube", true));
view.scene.addChild(container);
}
private function onResourceRetrieved(event : ResourceEvent) : void
{
var mesh : Mesh;
for (var i : int = 0; i < _container.numChildren; ++i)
{
mesh = Mesh(_container.getChildAt(i));
mesh.geometry.scale(0.1);
_mesh = mesh;
}
}
