 ## 目标
 实现实时的动画路径预览，快速定位关键帧，方便编辑切线。

 ## 解决
 为了可以实时预览动画路径，那么就需要获得当前 Animation 窗口的动画数据，但是 Unity 不开放操作 Animation 窗口类，只能通过反射来处理。 创建的 AnimationWindowUtil 类，即是为了与 Animation 窗口的数据进行交互。

 动画数据里面存储的是使用埃尔米特（Hermite）曲线公式的值，它是使用各个顶点的斜率来构建曲线，这也造成了在 Animation 窗口编辑切线的不便，没法精确控制斜率的值。
 
-![这里写图片描述](http://img.blog.csdn.net/20160923125916660)
+![](./Images/4.png)
 
 合适的方式是使用贝塞尔（Bézier）曲线，它提供了两个控制点来调整切线，控制点的位置比起控制斜率的值大小来的直观方便多了。好在这两种曲线公式是可以转换的，Hermite 曲线转换成 Bézier 曲线步骤如下：

 转换完成之后，则可通过绘制 Bézier 曲线，将动画路径展现出来。

 绘制的绿色点是每个关键帧的位置，点中绿色点，即可直接在 Animation 窗口定位到当前关键帧，方便直接立即编辑。点中绿色点时，会在该点的旁边出现灰色控制点，直接点中控制点，就可以直接调整该点的切线了。

 这样来调整切线比在 Animation 窗口里面进行调整斜率方便的多了。切线调整完成后，通过 Bézier 曲线转换成 Hermite  曲线，来写回动画数据。

 当关键帧过多时，可能会遮挡住曲线的走向绘制，特别是在转弯的地方，故也提供关闭显示关键帧点的功能。
