效果如下(双击log就会打印其内容)：

核心在于OnOpenAssetAttribute，其API介绍如下：

https://docs.unity3d.com/ScriptReference/Callbacks.OnOpenAssetAttribute.html

当在unity中双击打开一个资源就会回调方法，当返回true时表示已经对打开资源进行了处理；当返回false时表示会用一个外部工具打开资源(例如双击log打开调用脚本)

这个属性可以传入一个int型参数(起始为0)，表示调用先后，例如OnOpenAssetAttribute(0)比OnOpenAssetAttribute(1)先调用
