《转》Unity3D研究院编辑器之创建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)]
    public static void CreatNewLua()
    {
        ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0,
        ScriptableObject.CreateInstance<MyDoCreateScriptAsset>(),
        GetSelectedPathOrFallback() + "/New Lua.lua",
        null,
       "Assets/Editor/Lua/Template/lua.lua");
    }

    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
{

    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);
        StreamReader streamReader = new StreamReader(resourceFile);
        string text = streamReader.ReadToEnd();
        streamReader.Close();
        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);
        //}
        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);
        return AssetDatabase.LoadAssetAtPath(pathName, typeof(UnityEngine.Object));
    }

}

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

然后可以输入Lua脚本的类名

然后就根据自己创建Lua的文件名 正则替换模板里的东西了。
