MovieScene3D与Scene3D区别
cy3502398 (2009-01-14 11:36:20)

MovieScene3D与Scene3D区别是什么？能否给个实例！谢谢！！

(2009-01-14 12:03:37)		 MovieScene3D等于Scene3D里面每个物体.container的效果。

MovieScene3D直接可以给每个单个物体加sprite可以加的方法，弊端是分散的，没法一起加方法。

Scene3D是个整体的，弊端是加sprite方法的时候要用.container

总体来说没什么大不了的区别，呵呵。

(2009-01-14 12:38:27)		 container是它的方法还是新建的一个容器对象？
var container:Sprite = new Sprite();
是上面那个container容器吗？

(2009-01-14 12:41:44)		 上面我标注的两个container指同一个吗？
flash 3d 研究所 cy3502398
(2009-01-14 12:46:34)		 将上面这句
var scene:MovieScene3D = new MovieScene3D(container);
改为
var scene:Scene3D = new Scene3D(container);后只出现一张图片，而保留上面的将会正确显示！
而如果像DDM君所说的那样MovieScene3D代表分散的，而Scene3D代表整体的，情况应该会相反啊！
flash 3d 研究所 DDM君
(2009-01-14 14:25:16)		 两种声明都不需要参数，直接
var scene:Scene3D = new Scene3D;
就可以了
每个物体用
scene.addChild(物体);

欢迎看看我们的教程范例。
