tolua导入插件思路:其实框架里面都已经做好了扩展接口ToLuaExport.cs 里面的ProcessExtends函数。
注意:extendName = “ToLua_” + className.Replace(“.”, “ ”); 这是tolua约束好的格式以Tolua 开头,也就是说插件导出来的函数名必须以Tolua开头,而且className也约束了这个函数将写入到哪个wrap。

extendType = Type.GetType(extendName + “, Assembly-CSharp-Editor”);后面就是type.GetMethods获取所有的方法进行读入,写入。

extendType.GetField(“AdditionNameSpace”); 这句大概就是加入的头 ,如果你需要加入头就在导出的插件函数这个字段写入头字段。比如你要导入的头是Dotween—>public static string AdditionNameSpace = “DG.Tweening”;

下面是操作步骤:

在LuaFramework/Editor下创建两个文件夹分别为LuaExtensions和Wrap,创建ToLuaFile.cs和ToLuaFileExport.cs放在LuaExtensions文件夹下。

ToLuaFile.cs

using System;
public static class ToLuaFile {
    public static Type[] exports = new Type[]
        typeof(DG.Tweening.TweenSettingsExtensions),
        typeof(DG.Tweening.ShortcutExtensions),
        typeof(DG.Tweening.TweenExtensions),

ToLuaFileExport.cs

using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Text;
using System.Collections.Generic;
using System;
using System.Reflection;
using System.IO;
public static class ToLuaFileExport
    [MenuItem("Lua/Export ToLuaExtendFile", false, 53)]
    public static void ExportToLuaExtendFile()
        if (!Application.isPlaying)
            EditorApplication.isPlaying = true;
        Type[] list = ToLuaFile.exports;
        Dictionary<Type, List<MethodInfo>> dicTypeMethods = new Dictionary<Type, List<MethodInfo>>();
        for (int i = 0; i < list.Length; ++i)
            Type type = list[i];
            List<MethodInfo> ltMethodInfo = new List<MethodInfo>();
            ltMethodInfo.AddRange(type.GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.Static | BindingFlags.IgnoreCase | BindingFlags.DeclaredOnly));
            for (int j = 0; j < ltMethodInfo.Count; ++j)
                MethodInfo method = ltMethodInfo[j];
                ParameterInfo[] parameterInfos = method.GetParameters();
                if (parameterInfos == null || parameterInfos.Length <= 0)
                    continue;
                Type parameterType = GetType(parameterInfos[0].ParameterType);
                if (parameterType.IsGenericParameter)
                    continue;
                if (dicTypeMethods.ContainsKey(parameterType))
                    dicTypeMethods[parameterType].Add(method);
                    List<MethodInfo> lt = new List<MethodInfo>();
                    lt.Add(method);
                    dicTypeMethods[parameterType] = lt;
        foreach (KeyValuePair<Type, List<MethodInfo>> pair in dicTypeMethods)
            if (pair.Key.IsGenericType)
                continue;
            SaveFile(pair.Key, pair.Value);
        EditorApplication.isPlaying = false;
        Debug.Log("Export ToLuaExtendFiles over");
        AssetDatabase.Refresh();
    static string ToLuaPath
            return Application.dataPath + @"/LuaFramework/Editor/Wrap/";
    static Type GetType(Type type)
        if (type.IsGenericParameter)
            return type.BaseType;
        return type;
    static string GetTypeStr(Type type)
        Type trueType = GetType(type);
        if (trueType == typeof(void))
            return "void";
            return ToLuaExport.GetTypeStr(trueType);
    static void SaveFile(Type type, List<MethodInfo> ltMethodInfo)
        string fileName = "ToLua_" + type.FullName.Replace(".", "_");
        string path = ToLuaPath + fileName + ".cs";
        if (File.Exists(path))
            File.Delete(path);
        List<string> ltUsing = new List<string>();
        ltUsing.Add("System");
        ltUsing.Add("UnityEngine");
        using (StreamWriter textWriter = new StreamWriter(path, false, Encoding.UTF8))
            StringBuilder usb = new StringBuilder();
            foreach (string str in ltUsing)
                usb.AppendFormat("using {0};\r\n", str);
            usb.AppendLine();
            usb.AppendFormat("public class {0}\r\n", fileName);
            usb.AppendLine("{\r\n");
            for (int i = 0; i < ltMethodInfo.Count; ++i)
                MethodInfo m = ltMethodInfo[i];
                string returnType = GetTypeStr(m.ReturnType);
                usb.AppendFormat("\tpublic {0} {1}(", returnType, m.Name);
                ParameterInfo[] parameterInfos = m.GetParameters();
                for(int j = 1; j < parameterInfos.Length; ++j)
                    ParameterInfo p = parameterInfos[j];
                    usb.AppendFormat("{0} arg{1}", GetTypeStr(p.ParameterType), j);
                    if (j < parameterInfos.Length - 1) usb.Append(", ");
                usb.Append(")");
                if (returnType == "void")
                    usb.Append("\t{}\r\n");
                    usb.Append("\t{ return default(" + returnType + "); }\r\n");
            usb.AppendLine("}\r\n");
            textWriter.Write(usb.ToString());
            textWriter.Flush();
            textWriter.Close();

修改ToLuaExport.cs SaveFile 函数如下:

static void SaveFile(string file)
        using (StreamWriter textWriter = new StreamWriter(file, false, Encoding.UTF8))
            StringBuilder usb = new StringBuilder();
            usb.AppendLineEx("//this source code was auto-generated by tolua#, do not modify it");
            foreach (string str in usingList)
                usb.AppendFormat("using {0};\r\n", str);
            usb.AppendLineEx("using LuaInterface;");
            if (ambig == ObjAmbig.All)
                usb.AppendLineEx("using Object = UnityEngine.Object;");
            if (NeedDotweenNamespace())//给导出dotween的文件新增dotween的命名空间
                usb.AppendLine("using DG.Tweening;");
            usb.AppendLineEx();
            textWriter.Write(usb.ToString());
            textWriter.Write(sb.ToString());
            textWriter.Flush();
            textWriter.Close();

添加NeedDotweenNamespace函数:

static bool NeedDotweenNamespace()
        //UnityEngine.Debug.Log(libClassName);
        switch (libClassName)
            case "Transform":
            case "AudioSource":
            case "Camera":
            case "Component":
            case "Light":
            case "Material":
            case "Sequence":
            case "Tween":
            case "Tweener":
            case "Rigidbody":
                return true;
        return false;

修改ProcessExtends函数:

static void ProcessExtends(List<MethodInfo> list)
        //这是tolua约束好的格式以Tolua_开头,也就是说插件导出来的函数名必须以Tolua开头,而且className也约束了这个函数将写入到哪个wrap
        extendName = "ToLua_" + className.Replace(".", "_");
        //后面就是type.GetMethods获取所有的方法读入,写入
        extendType = Type.GetType(extendName + ", Assembly-CSharp-Editor");
        List<string> removeMd = new List<string>();
        if (extendType != null)
            List<MethodInfo> list2 = new List<MethodInfo>();
            list2.AddRange(extendType.GetMethods(BindingFlags.Instance | binding | BindingFlags.DeclaredOnly));
            for (int i = list2.Count - 1; i >= 0; i--)
                if (list2[i].Name.Contains("op_") || list2[i].Name.Contains("add_") || list2[i].Name.Contains("remove_"))
                    if (!IsNeedOp(list2[i].Name))
                        //list2.RemoveAt(i);
                        continue;
                string removeMdName = list2[i].Name;
                if (!removeMd.Contains(removeMdName))//防止扩展函数里面重载函数被去除
                    removeMd.Add(removeMdName);
                    list.RemoveAll((md) => { return md.Name == removeMdName; });
                //list.RemoveAll((md) => { return md.Name == list2[i].Name; });
                if (!IsObsolete(list2[i]))
                    list.Add(list2[i]);
            //这句大概就是加入的头 ,如果你需要加入头就在导出的插件函数这个字段写入头字段。
            //比如你要导入的头是Dotween—>public static string AdditionNameSpace = "DG.Tweening";
            FieldInfo field = extendType.GetField("AdditionNameSpace");
            if (field != null)
                string str = field.GetValue(null) as string;
                string[] spaces = str.Split(new char[] { ';' });
                for (int i = 0; i < spaces.Length; i++)
                    usingList.Add(spaces[i]);

好了,现在可以导入插件了,以DoTween为例,在CustomSettings.cs中添加如下:

_GT(typeof(DG.Tweening.AutoPlay)),
        _GT(typeof(DG.Tweening.AxisConstraint)),
        _GT(typeof(DG.Tweening.Ease)),
        _GT(typeof(DG.Tweening.LogBehaviour)),
        _GT(typeof(DG.Tweening.LoopType)),
        _GT(typeof(DG.Tweening.PathMode)),
        _GT(typeof(DG.Tweening.PathType)),
        _GT(typeof(DG.Tweening.RotateMode)),
        _GT(typeof(DG.Tweening.ScrambleMode)),
        _GT(typeof(DG.Tweening.TweenType)),
        _GT(typeof(DG.Tweening.UpdateType)),
        _GT(typeof(DG.Tweening.DOTween)),
        _GT(typeof(DG.Tweening.DOVirtual)),
        _GT(typeof(DG.Tweening.EaseFactory)),
        _GT(typeof(DG.Tweening.Tweener)),
        _GT(typeof(DG.Tweening.Tween)),
        _GT(typeof(DG.Tweening.Sequence)),
        _GT(typeof(DG.Tweening.TweenParams)),
        _GT(typeof(DG.Tweening.DOTweenAnimation)),
        _GT(typeof(DG.Tweening.DOTweenPath)),
        _GT(typeof(DG.Tweening.DOTweenVisualManager)),
        _GT(typeof(DG.Tweening.Core.ABSSequentiable)),
        //注意遇到泛型的要指明类型导出。
        _GT(typeof(DG.Tweening.Core.TweenerCore<Vector3, Vector3, DG.Tweening.Plugins.Options.VectorOptions>)).SetWrapName("TweenerCoreV3V3VO").SetLibName("TweenerCoreV3V3VO"),

好了重新Wrap。

DoTweenTest.cs

public class DoTweenTest : MonoBehaviour {
    private LuaState lua;
    void Start ()
        lua = new LuaState();
        lua.Start();
        LuaBinder.Bind(lua);
        lua.DoFile("Main.lua");
        LuaFunction main = lua.GetFunction("Main");
        main.Call();
        main.Dispose();
        main = null;

Main.lua

--主入口函数。从这里开始lua逻辑
require "UnityEngine/Vector3"
require "Common/define"
function Main()                 
    --AddEvent();
    DoTween()
function DoTween()
    local go = GameObject.Find("Cube");
    local sequence =  DG.Tweening.DOTween.Sequence();
    sequence:Append(go.transform:DOLocalMove(Vector3.New(10,0,0),3,false))
    :SetEase(DG.Tweening.Ease.Linear);
    sequence:OnComplete(Complete);
    --sequence:SetLoops(-1,DG.Tweening.LoopType.Yoyo);
function Complete()
    print("222");

这边提一下:

sequence:Append(go.transform:DOLocalMove(Vector3.New(10,0,0),3,false))

在c#中DOLocalMove的第三个参数可以省略,但在lua是不可以省略的,注意一下,是不是所有c#可省的,在lua中都不可省的呢?有待研究。

笔者也是刚刚接触LuaFramework,博文只是作为学习笔记与大家分享,希望能与大家共同进步。

每天进步一点点。
