  bezier: { 
    type: 'soft', 
    autoRotate: true,
    vars: [
      { x: 150, y: 150 },

GSAP JS基础教程

GreenSock在Flash动画时代久负盛名，并且GreenSock的维护团队与时俱进，推出了以javascript为核心的
GreenSock，在Flash和HTML5项目中，你可以使用相同的动画工具集，同样的API，同样的开发体验，同
样关注性能。

它具有以下优点:
1、速度快。GSAP专门优化了动画性能，使之实现和CSS一样的高性能动画效果。
2、轻量与模块化。模块化与插件式的结构保持了核心引擎的轻量，TweenLite包非常小（基本上低于
7kb）。GSAP提供了TweenLite, TimelineLite, TimelineMax 和 TweenMax不同功能的动画模块，你可以按
需使用。
3、没有依赖。
4、灵活控制。不用受限于线性序列，可以重叠动画序列，你可以通过精确时间控制，灵活地使用最少的
代码实现动画。
5、任何对象都可以实现动画。
