标题: Flash3D学习——Sandy学习笔记 [7]

刚才实现了将两个实例放进一个组里，可以实现联动的效果，那么单独的实例能否单独定义呢？
当然可以。

下面将两个实例，以Y轴实现旋转。

这里用到了，pan 属性，实现的是实例沿Y轴旋转。
代码：

import flash.events.*;

import flash.display.Bitmap;

import flash.display.BitmapData;

import flash.display.Loader;

import flash.net.URLRequest;

public class fuxi extends Sprite

      private var scene:Scene3D;

      private var camera:Camera3D;

      public function fuxi() {

         stage.scaleMode = StageScaleMode.NO_SCALE;

         stage.align = StageAlign.TOP_LEFT;

         //创建一个摄像机

         camera = new Camera3D(300, 300);

         camera.x = 100;

         camera.y = 100;

         camera.z = -300;

         camera.lookAt(0,0,0);

         //创建一个 Group

         var root:Group = createScene();

         //创建场景

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

         //创建实时侦听

         addEventListener( Event.ENTER_FRAME, enterFrameHandler );

         stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);

      }

      var box = new Box("box", 100, 100, 100);

      var myCone = new Cone("myCone", 50, 100);

      var myHedra = new Hedra( "myHedra", 80, 60, 60);

      var tg:TransformGroup;

      var Plane

      public function createScene() {

         var g:Group = new Group();



         //在场景画一个坐标定位点

ine3D = new Line3D( "y-coord", new Point3D(0, -20, 0), new Point3D( 0, 20, 0 ));

var myZLine

ine3D = new Line3D( "z-coord", new Point3D(0, 0, -20), new Point3D( 0, 0, 20 ));

         //创建一个新组

         tg = new TransformGroup('myGroup');

         //定义圆锥体和多面体的坐标

         myCone.x = -160;

         myCone.z = 150;

         myHedra.x = 90;

         //复习一下为物体着色吧

         var materialAttr:MaterialAttributes = new MaterialAttributes(

            new LineAttributes( 0.5, 0x2111BB, 0.4 ),

            new LightAttributes( ***e, 0.1)

            );

         var material:Material = new ColorMaterial( 0xFFCC33, 1, materialAttr );

         material.lightingEnable = ***e;

         var app:Appearance = new Appearance( material );

         myCone.appearance = app;

         myHedra.appearance = app;

         //将两个物体放进新的组里

         tg.addChild(myCone);

         tg.addChild(myHedra);

         g.addChild(tg);

         g.addChild(myXLine);

         g.addChild(myYLine);

         g.addChild(myZLine);

         //g.addChild( myCone );

         //g.addChild( myHedra );

         return g;

      }

      public function enterFrameHandler(_evt:Event) {

         //box.rotateX = mouseX;

         //box.rotateY = mouseY;

         myHedra.pan += 4;

         myCone.pan -= 4;

         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:

                  tg.roll +=2;

                  break;

            case Keyboard.LEFT:

                  tg.roll -=2;

                  break;

         }

      }

}

}
效果：
