Xlua原理 二
一已经介绍了初步的lua与C#通讯的原理，和xlua的LuaEnv的初始化内容。这边介绍下Wrap文件。
一.Wrap介绍
https://i-blog.csdnimg.cn/direct/ff2ece4f069840f195024f0201860e5e.png
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#时举行映射查找用的中间代码。如许就不需要去反射调用节约性能。
https://i-blog.csdnimg.cn/direct/2d03e9a6e26646fe84a7875e30ab5cf9.png
这里以Vector3Wrap文件为例：
先看一眼Wrap文件布局
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.normalized
CS.UnityEngine.Debug.Log(v2.x)
local v3 = v1 + v2
local 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);
....
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假造机注册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，末了再举行压栈操作供lua利用。
这块看出来，实际上lua还是去调用C#的代码，而且伴随压栈出栈操作。这就是为什么我们的lua的代码减少 . 如许的调用能节约一些性能的缘故原由。
再换个函数Set
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#的布局体、类都是UserData。C#想要去改变lua内的内存利用
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))
");
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_2018
if (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;
}
#endif
return 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举行注册方法，加入到objects举行维护。
https://i-blog.csdnimg.cn/direct/5383df7b16b24c13853fa1fb433265d5.png
额外测试了删除，发现假如不触发gc，object池不会删除对象，哪怕C#实际上已经删除了
https://i-blog.csdnimg.cn/direct/5ffb55a1cf444f23bc53ef668d01f619.png
总结：Wrap文件是lua与C#通讯中间代码文件，主要实现方式就是从lua堆栈取出lua数据对象，调用C#代码然后把效果再压栈到堆栈中。
像代码
local v1 = CS.UnityEngine.Vector3(1,2,3)
v1:Set(4,5,6)
性能显着要优于
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网络这种范例需要导出的对象
•2.通过LuaTemplate把对应的.tpl.txt文件转成可实验的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.实验lua代码生成wrap文件
映射模板目录：

生成中间代码文件部分
https://i-blog.csdnimg.cn/direct/37aafd072a134a55a29932dddaf63c1a.png
XLua.Utils.GetAllTypes:网络工程全部元数据
ps:这步可以直接举行改造，让其直接对有效元数据举行筛选，稍微节约一点编译时间
GetGenConfig：对元数据举行过滤筛选出需要lua与C#通讯的元数据
以Lua通讯C#代码为例：
老师成一个List，然后去获取全部打上LuaCallCSharp标签的元数据，举行添加，末了在用Linq表达式举行一遍筛选。

https://i-blog.csdnimg.cn/direct/b2dc13df75c4463787fd3fe1e56cd6f1.png
实验脚本TemplateCommon,在lua里填充table数据，构造好后去生成Wrap文件
对于每个类都会走到GenOne来生成Wrap文件
