在3d立方体上添加动画片段并与其进行交互

Question

我使用下面的代码创建了一个旋转的多维数据集，并将位图添加为多维数据集的边。我想知道是否可以将影片剪辑分配为立方体的侧面，以便与它们进行一些交互。

    import flash.events.Event;
    import flash.display.Bitmap;
    import flash.display.BitmapData;

    import org.papervision3d.cameras.CameraType;
    import org.papervision3d.materials.BitmapMaterial;
    import org.papervision3d.materials.ColorMaterial;
    import org.papervision3d.materials.WireframeMaterial;
    import org.papervision3d.materials.utils.MaterialsList;
    import org.papervision3d.objects.primitives.Cube;
    import org.papervision3d.view.BasicView;

            var cube : Cube;                    
            var basicview : BasicView = new BasicView(640, 480, true, false, CameraType.FREE); 
            addChild(basicview);
            var logo : Logo = new Logo( 0,0); //Bitmapdata (jpeg) exported as class Logo from library   
            var matFront : BitmapMaterial = new BitmapMaterial(logo);
            var matBack : BitmapMaterial = new BitmapMaterial(logo); 

            var ml : MaterialsList = new MaterialsList(); 

            ml.addMaterial(matFront, "front"); 
            ml.addMaterial(matBack, "back"); 
            ml.addMaterial(new ColorMaterial(0x551F92),"right"); 
            ml.addMaterial(new ColorMaterial(0x431872),"bottom"); 
            ml.addMaterial(new ColorMaterial(0x341359),"top"); 
            ml.addMaterial(new ColorMaterial(0x7429C7),"left"); 

            cube = new Cube(ml,200,200,200,5,5,5); 

            basicview.scene.addChild(cube); 
            basicview.camera.fov = 20;          

            addEventListener(Event.ENTER_FRAME, enterFrame);                
            function enterFrame(e:Event) : void
            {
                cube.yaw((320-mouseX)*0.01); 
                cube.pitch((240-mouseY)*0.01); 
            }
            basicview.singleRender(); 
        }

UPDATE

我添加此

var matFront : MovieMaterial = new MovieMaterial(new MV(),false,true);
matFront.interactive = true ;

MV只是一个带有此代码的正方形

package Scripts {

    import flash.display.MovieClip;
    import flash.events.*;

    public class MV extends MovieClip
    {
        public function MV( ) 
        {
            buttonMode = true;
            addEventListener(MouseEvent.CLICK,traceFunction);
        }
        private function traceFunction(ev:MouseEvent) {
            trace("clicked");
        }
    }
}

为什么单击影片剪辑的侧面时没有任何交互？

UPDATE 2

好吧，我找到了我必须添加此行

basicview.viewport.interactive = true;

但是为什么即使在动画片段的侧面不可见的情况下我也要进行交互。

如何避免？

Answer 1

是的，您有可能必须从想要使用的MovieClips创建材质，为此，请查看MovieMaterial中的类MovieAssetMaterial和papervision3d materials Package。
