@# Unity编辑器扩展

需求：

立项之后需要每位参与项目的程序在创建.cs脚本时添加功能描述、创建时间、创建者等多种类型的脚本说明。

---

思路：

UnityEditor在对资源进行操作时需要调用AssetModificationProcessor

AssetModificationProcessor

Description：

AssetModificationProcessor lets you hook into saving of serialized assets and scenes which are edited inside Unity.
This lets you prevent writing of assets by Unity for integration with VCS solutions like Perforce which require locking of files.
This can be used as a callback to know when Assets are saved. You can then make actions such as run code generator.

Messages

Method	Description
IsOpenForEdit	This is called by Unity when inspecting an asset to determine if an editor should be disabled.
OnWillCreateAsset	Unity calls this method when it is about to create an Asset you haven’t imported (for example, .meta files).
OnWillDeleteAsset	This is called by Unity when it is about to delete an asset from disk.
OnWillMoveAsset	Unity calls this method when it is about to move an Asset on disk.
OnWillSaveAssets	This is called by Unity when it is about to write serialized assets or Scene files to disk.

实现

在Editor目录下创建脚本EditScriptTemplates.cs，脚本如下：

using System.IO;public class EditScriptTemplates : UnityEditor.AssetModificationProcessor
{private static string s_tempStr ="// ==============================================\r\n"+ "// 功能描述：\r\n"+ "// 创建时间：#CreatTime#\r\n"+ "// 作 者：\r\n"+ "// 版 本：v1.00\r\n"+ "// ==============================================\r\n";public static void OnWillCreateAsset(string path){//忽略metapath = path.Replace(".meta", "");//cs脚本添加注释if (path.EndsWith(".cs")){//在.cs文件内容前添加默认的注释s_tempStr += File.ReadAllText(path);//更新注释中的时间s_tempStr = s_tempStr.Replace("#CreatTime#",System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));//文件写入File.WriteAllText(path, s_tempStr);}}
}

效果测试：

在工程其他目录创建脚本Test.cs，效果如下：
