Unity3D定制新建C#文件的头描述

1. 修改模板内容如下：

MAC：Unity.app/Contents/Resources/ScriptTemplates/81-C# Script-NewBehaviourScript.cs.txt

WIN：\Unity\Editor\Data\Resources\ScriptTemplates

 /*
     Author:        #AuthorName#
     CreateDate: #CreateDate#
     Desc:           注释
 */
 using UnityEngine;
 using System.Collections;

 public class #SCRIPTNAME# : MonoBehaviour {

     // Use this for initialization
     void Start () {

     }

     // Update is called once per frame
     void Update () {

     }
 }

2.在Editor目录下放置文件CSharpCreateDesc.cs

 using UnityEngine;
 using System.Collections;
 using System.IO;
 using System;
 using UnityEditor;  

 public class ScriptCreateDesc : UnityEditor.AssetModificationProcessor
 {
     private static void OnWillCreateAsset(string path)
     {
         path = path.Replace(".meta","");
         if (path.EndsWith(".cs"))
         {
             string strContent = File.ReadAllText(path);
             strContent = strContent.Replace("#AuthorName#", "AndyZheng").Replace("#CreateDate#", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
             File.WriteAllText(path, strContent);
             AssetDatabase.Refresh();
         }
     }
 }
