Away3D基础教程（二）：加载外部模型[通俗易懂]

_view = new View3D();
//背景色
_view.backgroundColor = 0x666666;
//抗锯齿参数
_view.antiAlias = 4;
this.addChild(_view);

this.addEventListener(Event.ENTER_FRAME, onEnterFrame);
stage.addEventListener(MouseEvent.MOUSE_WHEEL,onWheel);

//Parsers.enableAllBundled()这样away3d就能解析所有它能解析的格式了
Parsers.enableAllBundled();
            
_loader = new Loader3D();
_loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE,onResourceComplete);
//_loader.addEventListener(AssetEvent.ASSET_COMPLETE,assetComplete);
_loader.addEventListener(LoaderEvent.LOAD_ERROR, onLoadError);
//AntModel为绑定嵌入的模型资源
_loader.loadData(new AntModel());

_loader.removeEventListener(LoaderEvent.RESOURCE_COMPLETE,onResourceComplete);
_loader.removeEventListener(LoaderEvent.LOAD_ERROR, onLoadError);
_view.scene.addChild(_loader);
_view.camera.z=1000;
_view.camera.lookAt(_loader.position);
