Xlua原理 二

一已经介绍了初步的lua与C#通信的原理，和xlua的LuaEnv的初始化内容。

这边介绍下Wrap文件。

一.Wrap介绍

导入xlua后可以看到会多出上图菜单。

点击后生成一堆wrap文件，这些文件是lua调用C#时进行映射查找用的中间代码。这样就不需要去反射调用节约性能。

这里以Vector3Wrap文件为例：

先看一眼Wrap文件结构

   public class UnityEngineVector3Wrap {public static void __Register(RealStatePtr L){ObjectTranslator translator = ObjectTranslatorPool.Instance.Find(L);System.Type type = typeof(UnityEngine.Vector3);Utils.BeginObjectRegister(type, L, translator, 6, 6, 6, 3);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__add", __AddMeta);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__sub", __SubMeta);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__unm", __UnmMeta);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__mul", __MulMeta);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__div", __DivMeta);Utils.RegisterFunc(L, Utils.OBJ_META_IDX, "__eq", __EqMeta);Utils.RegisterFunc(L, Utils.METHOD_IDX, "Set", _m_Set);Utils.RegisterFunc(L, Utils.METHOD_IDX, "Scale", _m_Scale);Utils.RegisterFunc(L, Utils.METHOD_IDX, "GetHashCode", _m_GetHashCode);Utils.RegisterFunc(L, Utils.METHOD_IDX, "Equals", _m_Equals);Utils.RegisterFunc(L, Utils.METHOD_IDX, "Normalize", _m_Normalize);Utils.RegisterFunc(L, Utils.METHOD_IDX, "ToString", _m_ToString);...}...}    

 private void Demo4(){LuaEnv luaenv = new LuaEnv();luaenv.DoString(@"local v1 = CS.UnityEngine.Vector3(10,10,10)local v2 = v1.normalizedCS.UnityEngine.Debug.Log(v2.x)local v3 = v1 + v2local v4 = CS.UnityEngine.Vector3.Distance(v1,v2)v1:Set(5,6,7)CS.UnityEngine.Debug.Log(v1.x)");luaenv.Dispose();}

以调用到normalized为例

Utils.RegisterFunc(L, Utils.GETTER_IDX, "normalized", _g_get_normalized);....[MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]static int _g_get_normalized(RealStatePtr L){try {ObjectTranslator translator = ObjectTranslatorPool.Instance.Find(L);UnityEngine.Vector3 gen_to_be_invoked;translator.Get(L, 1, out gen_to_be_invoked);translator.PushUnityEngineVector3(L, gen_to_be_invoked.normalized);} catch(System.Exception gen_e) {return LuaAPI.luaL_error(L, "c# exception:" + gen_e);}return 1;}

上面那步在lua虚拟机注册normalized，对应是C#里的函数。

函数中先获得Vector3变量然后调用C#中的normalized，最后再进行压栈操作供lua使用。

这块看出来，实际上lua还是去调用C#的代码，并且伴随压栈出栈操作。这就是为什么我们的lua的代码减少 . 这样的调用能节约一些性能的原因。

再换个函数Set

       [MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]static int _m_Set(RealStatePtr L){try {ObjectTranslator translator = ObjectTranslatorPool.Instance.Find(L);UnityEngine.Vector3 gen_to_be_invoked;translator.Get(L, 1, out gen_to_be_invoked);{float _newX = (float)LuaAPI.lua_tonumber(L, 2);float _newY = (float)LuaAPI.lua_tonumber(L, 3);float _newZ = (float)LuaAPI.lua_tonumber(L, 4);gen_to_be_invoked.Set( _newX, _newY, _newZ );translator.UpdateUnityEngineVector3(L, 1, gen_to_be_invoked);return 0;}} catch(System.Exception gen_e) {return LuaAPI.luaL_error(L, "c# exception:" + gen_e);}}

前面的部分跟normalized差不多看下UpdateUnityEngineVector3部分

public void UpdateUnityEngineVector3(RealStatePtr L, int index, UnityEngine.Vector3 val){if (LuaAPI.lua_type(L, index) == LuaTypes.LUA_TUSERDATA){if (LuaAPI.xlua_gettypeid(L, index) != UnityEngineVector3_TypeID){throw new Exception("invalid userdata for UnityEngine.Vector3");}IntPtr buff = LuaAPI.lua_touserdata(L, index);if (!CopyByValue.Pack(buff, 0,  val)){throw new Exception("pack fail for UnityEngine.Vector3 ,value="+val);}}else{throw new Exception("try to update a data with lua type:" + LuaAPI.lua_type(L, index));}}

这里看到对应lua来说C#的结构体、类都是UserData。C#想要去改变lua内的内存使用

CopyByValue.Pack函数进行拷贝

再拿个GameObject的Component举例，加深下印象：

luaenv.DoString(@"local v1 = CS.UnityEngine.GameObject()local v2 = v1:AddComponent(typeof(CS.UnityEngine.Camera))");[MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]static int _m_AddComponent(RealStatePtr L){try {ObjectTranslator translator = ObjectTranslatorPool.Instance.Find(L);UnityEngine.GameObject gen_to_be_invoked = (UnityEngine.GameObject)translator.FastGetCSObj(L, 1);{System.Type _componentType = (System.Type)translator.GetObject(L, 2, typeof(System.Type));var gen_ret = gen_to_be_invoked.AddComponent( _componentType );translator.Push(L, gen_ret);return 1;}} catch(System.Exception gen_e) {return LuaAPI.luaL_error(L, "c# exception:" + gen_e);}}

这里有个函数getCsObj用于取游戏对象

private object getCsObj(RealStatePtr L, int index, int udata){object obj;if (udata == -1){if (LuaAPI.lua_type(L, index) != LuaTypes.LUA_TUSERDATA) return null;Type type = GetTypeOf(L, index);if (type == typeof(decimal)){decimal v;Get(L, index, out v);return v;}GetCSObject get;if (type != null && custom_get_funcs.TryGetValue(type, out get)){return get(L, index);}else{return null;}}else if (objects.TryGetValue(udata, out obj)){
#if !UNITY_5 && !XLUA_GENERAL && !UNITY_2017 && !UNITY_2017_1_OR_NEWER && !UNITY_2018if (obj != null && obj is UnityEngine.Object && ((obj as UnityEngine.Object) == null)){//throw new UnityEngine.MissingReferenceException("The object of type '"+ obj.GetType().Name +"' has been destroyed but you are still trying to access it.");return null;}
#endifreturn obj;}return null;}

这里从一个objects字典去查找游戏的对象。跟Vector3有区别。lua创建GameObject的过程会走CS的元表方法（在上篇有介绍），调用c#的Import方法，会把这个GameObject进行注册方法，加入到objects进行维护。

额外测试了删除，发现如果不触发gc，object池不会删除对象，哪怕C#实际上已经删除了

总结：Wrap文件是lua与C#通信中间代码文件，主要实现方式就是从lua堆栈取出lua数据对象，调用C#代码然后把结果再压栈到堆栈中。

像代码 

local v1 = CS.UnityEngine.Vector3(1,2,3)

v1:Set(4,5,6)

性能明显要优于

v1.x = 4

v2.y = 5

v3.z = 6

压栈少了4次，拷贝次数少了2次

二.Wrap文件生成

•流程：

•1.Generator收集这种类型需要导出的对象

•2.通过LuaTemplate把对应的.tpl.txt文件转成可执行的lua代码

•3.在GenOne方法里给上一步生成的lua代码赋值全局变量

•4.执行lua代码生成wrap文件

映射模板目录：

生成中间代码文件部分

XLua.Utils.GetAllTypes:收集工程所有元数据

ps:这步可以直接进行改造，让其直接对有效元数据进行筛选，稍微节约一点编译时间

GetGenConfig：对元数据进行过滤筛选出需要lua与C#通信的元数据

以Lua通信C#代码为例：

先生成一个List，然后去获取所有打上LuaCallCSharp标签的元数据，进行添加，最后在用Linq表达式进行一遍筛选。

执行脚本TemplateCommon,在lua里填充table数据，组织好后去生成Wrap文件

对于每个类都会走到GenOne来生成Wrap文件

以GameObjectWrap文件生成为例：

模板对应文件：

到这里看到模板在内存中对应变成了一个生成的方法，对应传进C#的替换字符。

替换比较复杂不一一分析了。大概就是C#对应类的成员变量，静态方法等所有元数据替换成table的表里，一个循环遍历进行插入字符比如下面的GameObject的构造函数
