使用编辑器批量修改UGUI射线

如果项目UI管理不好，前期会出现很多不需要点击事件，但又打开着UI的Raycast Target属性，这个是很耗性能的。

然而 项目进行到一定时间再去管理UI射线，显然是很麻烦耗时的。

今天给大家通过Unity编辑器 来实现批量修改UI射线属性的工具。

工具图：

使用方法：

一、将下面脚本Copy到项目里，然后点击“Tools/检查UGUI射线”按钮

二、在“Hierarchy”或“Project”面板选择想要修改射线的预设体（可以多选）

三、点击“检查选中UI”按钮，然后所有带射线的UI都会显示在下面

四、可以点击每个UI前方的单选框按钮来设置UI射线状态、也可以点击“移除全部射线”按钮来移除当前显示的所有射线

五、改后可以查看之前选择的预设体，看看是不是改好了呢~~

上脚本：

        window.Show();
