（十六）创建Lua脚本模板

Unity里能创建 c#脚本模板，但是如果我想创建Lua脚本模板怎么办呢？拓展一下编辑器吧。

设置一下Lua脚本的模板地址： Assets/Editor/Lua/Template/lua.lua

 
using UnityEngine;
using UnityEditor;
using System;
using System.IO;
using System.Text;
using UnityEditor.ProjectWindowCallback;
using System.Text.RegularExpressions;public class Test
{[MenuItem("Assets/Create/Lua Script", false, 80)]   // 参数三，表示优先级，越大越在顶部public static void CreatNewLua(){ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0,ScriptableObject.CreateInstance<MyDoCreateScriptAsset>(),GetSelectedPathOrFallback() + "/New Lua.lua",null,"Assets/Editor/Lua/Template/lua.lua");}// 获取选择的路径public static string GetSelectedPathOrFallback(){string path = "Assets";foreach (UnityEngine.Object obj in Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.Assets)){path = AssetDatabase.GetAssetPath(obj);if (!string.IsNullOrEmpty(path) && File.Exists(path)){path = Path.GetDirectoryName(path);break;}}return path;}
}    class MyDoCreateScriptAsset : EndNameEditAction
{// 输入Lua文件名后的操作，写入lua文件，并替换文件名public override void Action(int instanceId, string pathName, string resourceFile){UnityEngine.Object o = CreateScriptAssetFromTemplate(pathName, resourceFile);ProjectWindowUtil.ShowCreatedAsset(o);}internal static UnityEngine.Object CreateScriptAssetFromTemplate(string pathName, string resourceFile){string fullPath = Path.GetFullPath(pathName);// 读取模板StreamReader streamReader = new StreamReader(resourceFile);string text = streamReader.ReadToEnd();streamReader.Close();// 根据文件名修改内容string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(pathName);text = Regex.Replace(text, "#NAME#", fileNameWithoutExtension);//string text2 = Regex.Replace(fileNameWithoutExtension, " ", string.Empty);//text = Regex.Replace(text, "#SCRIPTNAME#", text2);//if (char.IsUpper(text2, 0))//{//    text2 = char.ToLower(text2[0]) + text2.Substring(1);//    text = Regex.Replace(text, "#SCRIPTNAME_LOWER#", text2);//}//else//{//    text2 = "my" + char.ToUpper(text2[0]) + text2.Substring(1);//    text = Regex.Replace(text, "#SCRIPTNAME_LOWER#", text2);//}// 写入lua脚本bool encoderShouldEmitUTF8Identifier = true;bool throwOnInvalidBytes = false;UTF8Encoding encoding = new UTF8Encoding(encoderShouldEmitUTF8Identifier, throwOnInvalidBytes);bool append = false;StreamWriter streamWriter = new StreamWriter(fullPath, append, encoding);streamWriter.Write(text);streamWriter.Close();AssetDatabase.ImportAsset(pathName);    // 导入Unity，此处的路径必须是资源路径，从Assets开始。return AssetDatabase.LoadAssetAtPath(pathName, typeof(UnityEngine.Object)); // 加载}}

因为是模板就可以添加一些预制代码在上面，当填写完类名后可以来替换操作，例如unity自带的创建C#文件，外面写了类名里面也跟这变。Creat -> Lua Script
