1. 画圆，有填充；画大椭圆，无填充。说明：小球是运动物体、大椭圆是路径

2. 使用 选择工具 选择大椭圆 Ctrl+b 打散图形。 再选择一个小缺口，删除。

3、剪切大椭圆，右键点击图层1 添加引导层，选择 粘贴到当前位置。

4、插入补间动画 注意：小球是对象。
步骤：1.点 图层1 40帧 ，插入关键帧；创建补间动画：右键点 1-40之间任意一个帧，创建补间动画。
2．点 引导层40帧，插入帧 。
3.点图层1 第一帧 ，移动小球 到起始位置。

4、点图层1 末尾，移动小球到结束位置。

5、输出影片 ctrl+回车 看效果。
如果希望围绕着某物体，可以加一个图层，画某物体。结果看 引导层.swf。
如果改变引导层形状；结果看 引导层2.swf
