本文介绍如何在Unity中通过C#脚本实现Lua脚本文件的自动生成。包括Lua模板文件设置、C#脚本编写及菜单项集成等步骤。

1 . 在Project界面创建文件夹 Editor/Lua/Template/lua.lua 注：最后的文件lua.lua可以先创建一个C#然后改后缀，lua文件里可以随便写一些默认的值，我写的为“ print("#NAME#") ”。

2 . 创建C#脚本

using UnityEngine;
using UnityEditor;
using System;
using System.IO;
using System.Text;
using UnityEditor.ProjectWindowCallback;
using System.Text.RegularExpressions;

public class CreateLua {
    [MenuItem("Assets/Create/Lua Sctipt",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);

        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));
    }
}

3 . 保存，就可以了。注：我把这个C#脚本放在了文件夹Lua层级下，比较直观的知道这是创建lua用的。
