spark下_3D翻转特效（二）

一．基本讲解

1．   将DistortionEffects.swc文件拷贝到lib文件夹中

2．   引入需要用到的类库xmlns:mxeffects="com.adobe.ac.mxeffects.*"

3．   导入需要用到的类：DistortionConstants，Flip

import com.adobe.ac.mxeffects.DistortionConstants;

import com.adobe.ac.mxeffects.Flip;

4. 在时间的方法里面编写特效的关键代码：

n  创建Flip类的实例传递一个参数（当前对象的id）

n  指定目标对象的集合e.siblings = [ registration ];

n  指定旋转的方向e.direction = DistortionConstants.RIGHT;

n  指定旋转的时间短e.duration = 2000;

n  开发播放e.play();
