标题: Flash3D学习——Sandy学习笔记 [6]

总看这个立方体的确让人乏味，咱们接下来换个形状。参考官方例子试试圆锥体（Cone）和多面体（Hedra）。
这个例子中将两个实例合并在一个组里，并通过键盘控制组的移动，实现两个物体的联动效果。
代码：

      public function fuxi() {

         stage.scaleMode = StageScaleMode.NO_SCALE;

         stage.align = StageAlign.TOP_LEFT;

         //创建一个摄像机

         camera.x = 100;

         //创建一个 Group

         //创建场景

         scene = new Scene3D( "scene", this, camera, root );

         //创建实时侦听

         //定义圆锥体和多面体的坐标

         myCone.z = 150;

         myHedra.appearance = app;

         //将两个物体放进新的组里

         tg.addChild(myCone);

         //box.rotateY = mouseY;

         scene.render();

      }

      private function keyPressed(event:KeyboardEvent):void {

         switch(event.keyCode) {

            case Keyboard.UP:

                  tg.y +=2;

                  break;

            case Keyboard.DOWN:

                  tg.y -=2;

                  break;

            case Keyboard.RIGHT:

                  break;

            case Keyboard.LEFT:

                  break;

         }

      }

}

}
