Cocos2d-x Lua支持UWP
前言：UWP是微软搞的一个Windows通用平台，只要运行Win10的平板、电脑、Xbox以及以后微软推出的各种设备都能运行的一套应用框架。听起来十分诱人！游戏是应用中最重要的一个类别，我们广大开发者当然希望能分享这个市场。可是Cocos2d-x Lua对UWP的> 支持为零，官方明确不在此投入了，作为开发者十分伤心啊！那只能我们广大开发者自己动手了，下面是我实践的记录，最终是成功运行了Lua代码，但离跑完整的游戏还是有一定距离，特分享出来，希望借助开源的力量大家一起研究！
一、环境介绍
基于cocos2d-x 3.10版本，之前的版本对UWP的支持很差就不考虑了。我的思路是基于官方提供的cpp版本修改添加lua的支持
二、改造libluacocos2d为UWP工程
我的思路是基于win32版本修改，模仿win10的libcocos2d。比较核心的修改有：
 
修改项目依赖
依赖的libcocos2d修改为win10工程的
<ItemGroup>    <ProjectReference Include="..\..\..\2d\libcocos2d_win10\libcocos2d.vcxproj">      <Project>{07c2895d-720c-487d-b7b4-12c293ea533f}</Project>    </ProjectReference></ItemGroup>
 
重新定义项目的基本属性
<PropertyGroup Label="Globals">    <ProjectGuid>{9F2D6CE6-C893-4400-B50C-6DB70CC2562F}</ProjectGuid>    <Keyword>DynamicLibrary</Keyword>    <ProjectName>libluacocos2d</ProjectName>    <RootNamespace>libluacocos2d</RootNamespace>    <DefaultLanguage>en-US</DefaultLanguage>    <MinimumVisualStudioVersion>14.0</MinimumVisualStudioVersion>    <AppContainerApplication>true</AppContainerApplication>    <ApplicationType>Windows Store</ApplicationType>    <ApplicationTypeRevision>8.2</ApplicationTypeRevision>    <WindowsTargetPlatformVersion>10.0.14393.0</WindowsTargetPlatformVersion>    <WindowsTargetPlatformMinVersion>10.0.14393.0</WindowsTargetPlatformMinVersion></PropertyGroup>
 
修改cocos2d_headers.props成win10版本
我建立一个win10的cocos2d_headers_win10.props内容如下：
<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">  <ImportGroup Label="PropertySheets" />  <PropertyGroup Label="UserMacros">    <EngineRoot>$(MSBuildThisFileDirectory)..\..\</EngineRoot>  </PropertyGroup>  <PropertyGroup />  <ItemDefinitionGroup>    <ClCompile>      <AdditionalIncludeDirectories>$(EngineRoot)cocos;$(EngineRoot)cocos/editor-support;$(EngineRoot)cocos\platform\winrt;$(EngineRoot)external\glfw3\include\$(COCOS2D_PLATFORM);$(EngineRoot)external\$(COCOS2D_PLATFORM)-specific\gles\include\OGLES;$(EngineRoot)external\freetype2\include\$(COCOS2D_PLATFORM)\freetype2;$(EngineRoot)external\freetype2\include\$(COCOS2D_PLATFORM)\;$(EngineRoot)external</AdditionalIncludeDirectories>      <PreprocessorDefinitions>WINRT;_VARIADIC_MAX=10;NOMINMAX;GL_GLEXT_PROTOTYPES;_CRT_SECURE_NO_WARNINGS;_SCL_SECURE_NO_WARNINGS;_UNICODE;UNICODE;RAPIDJSON_ENDIAN=RAPIDJSON_LITTLEENDIAN;_USRJSSTATIC;%(PreprocessorDefinitions)</PreprocessorDefinitions>      <CompileAsWinRT>true</CompileAsWinRT>      <MultiProcessorCompilation>true</MultiProcessorCompilation>      <MinimalRebuild>false</MinimalRebuild>      <DebugInformationFormat>OldStyle</DebugInformationFormat>      <DisableSpecificWarnings>4056;4244;4251;4756;4453;28204;4099;</DisableSpecificWarnings>    </ClCompile>    <ProjectReference>      <UseLibraryDependencyInputs>false</UseLibraryDependencyInputs>    </ProjectReference>  </ItemDefinitionGroup>  <ItemGroup>    <BuildMacro Include="EngineRoot">      <Value>$(EngineRoot)</Value>      <EnvironmentVariable>true</EnvironmentVariable>    </BuildMacro>  </ItemGroup></Project>
 
修改头文件输入
angle的依赖修改为win10版本
<AdditionalIncludeDirectories>$(EngineRoot);$(EngineRoot)cocos\2d;$(EngineRoot)cocos\base;$(EngineRoot)cocos\3d;$(EngineRoot)cocos\physics;$(EngineRoot)cocos\physics3d;$(EngineRoot)cocos\audio\include;$(EngineRoot)cocos\ui;$(EngineRoot)cocos\navmesh;$(EngineRoot)external;$(EngineRoot)external\lua;$(EngineRoot)external\lua\lua;$(EngineRoot)external\lua\tolua;$(EngineRoot)external\lua\luajit\include;$(EngineRoot)external\libwebsockets\win10\include;$(EngineRoot)extensions;$(EngineRoot)cocos\editor-support;$(EngineRoot)cocos\editor-support\cocostudio;$(EngineRoot)cocos\editor-support\cocostudio\ActionTimeline;$(EngineRoot)cocos\editor-support\spine;$(EngineRoot)cocos\editor-support\cocosbuilder;$(EngineRoot)cocos\scripting\lua-bindings\manual;$(EngineRoot)cocos\scripting\lua-bindings\auto;$(EngineRoot)cocos\scripting\lua-bindings\manual\extension;$(EngineRoot)cocos\scripting\lua-bindings\manual\cocostudio;$(EngineRoot)cocos\scripting\lua-bindings\manual\ui;$(EngineRoot)cocos\scripting\lua-bindings\manual\cocos2d;$(EngineRoot)cocos\scripting\lua-bindings\manual\navmesh;$(EngineRoot)external\win10-specific\angle\include;$(EngineRoot)cocos\platform;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
 
宏定义修改
比较重要的是添加_USRLUASTATIC: 解决dllimport编译报错
<PreprocessorDefinitions>_USRDLL;_LIB;COCOS2DXWIN32_EXPORTS;_USE3DDLL;_EXPORT_DLL_;_USRSTUDIODLL;_USREXDLL;_USEGUIDLL;_USRLUASTATIC;_DEBUG;COCOS2D_DEBUG=1;_CRT_SECURE_NO_WARNINGS;_WINSOCK_DEPRECATED_NO_WARNINGS;%(PreprocessorDefinitions)</PreprocessorDefinitions>
 
对于里面的'.c'文件右键属性，如下图修改：
这是解决：D8048 无法使用 /ZW 选项编译 C 文件但项目整体是开启使用Windows运行时扩展
三、改造主工程，添加Lua支持
 
按照win32版本修改AppDelegate.cpp
非关键部分已省略
#include "AppDelegate.h"#include "scripting/lua-bindings/manual/CCLuaEngine.h"#include "scripting/lua-bindings/manual/lua_module_register.h"bool AppDelegate::applicationDidFinishLaunching() {    // initialize director    auto director = Director::getInstance();    auto glview = director->getOpenGLView();    if(!glview) {#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32) || (CC_TARGET_PLATFORM == CC_PLATFORM_MAC) || (CC_TARGET_PLATFORM == CC_PLATFORM_LINUX)        glview = GLViewImpl::createWithRect("MyCppGame", Rect(0, 0, designResolutionSize.width, designResolutionSize.height));#else        glview = GLViewImpl::create("MyCppGame");#endif        director->setOpenGLView(glview);    }    // turn on display FPS    director->setDisplayStats(true);    // set FPS. the default value is 1.0/60 if you don't call this    director->setAnimationInterval(1.0 / 60);    // register lua module    auto engine = LuaEngine::getInstance();    ScriptEngineManager::getInstance()->setScriptEngine(engine);    lua_State* L = engine->getLuaStack()->getLuaState();    lua_module_register(L);    LuaStack* stack = engine->getLuaStack();    stack->setXXTEAKeyAndSign("2dxLua", strlen("2dxLua"), "XXTEA", strlen("XXTEA"));    // Set the design resolution    //glview->setDesignResolutionSize(designResolutionSize.width, designResolutionSize.height, ResolutionPolicy::NO_BORDER);    //Size frameSize = glview->getFrameSize();    // if the frame's height is larger than the height of medium size.    //if (frameSize.height > mediumResolutionSize.height)    //{            //    director->setContentScaleFactor(MIN(largeResolutionSize.height/designResolutionSize.height, largeResolutionSize.width/designResolutionSize.width));    //}    // if the frame's height is larger than the height of small size.    //else if (frameSize.height > smallResolutionSize.height)    //{            //    director->setContentScaleFactor(MIN(mediumResolutionSize.height/designResolutionSize.height, mediumResolutionSize.width/designResolutionSize.width));    //}    // if the frame's height is smaller than the height of medium size.    //else    //{            //    director->setContentScaleFactor(MIN(smallResolutionSize.height/designResolutionSize.height, smallResolutionSize.width/designResolutionSize.width));    //}    register_all_packages();    if (engine->executeScriptFile("src/main.lua"))    {        return false;    }    // create a scene. it's an autorelease object    //auto scene = HelloWorld::createScene();    // run    //director->runWithScene(scene);    return true;}
 
修改头文件输入
..\..\Classes;$(EngineRoot);$(EngineRoot)cocos\audio\include;$(EngineRoot)external;$(EngineRoot)external\lua;$(EngineRoot)external\lua\luajit\include;$(EngineRoot)external\lua\tolua;$(EngineRoot)extensions;$(EngineRoot)cocos\scripting\lua-bindings\manual;$(EngineRoot)cocos\scripting\lua-bindings\auto;Cocos2dEngine;Generated Files\Cocos2dEngine;%(AdditionalIncludeDirectories)
 
添加宏定义
_USRLUASTATIC;%(PreprocessorDefinitions)
 
关闭链接库警告
 
运行试试Lua啦
Lua代码放在Resources\src里面我的项目运行效果如下：
四、工程地址
工程的Github地址。欢迎大家提交pull request😀
五、目前面临的问题
 
无法编译x64位版本，官方的c++版本uwp工程也不能编译x64版本
 
有链接错误，重复定义。目前通过编译项忽略，未知潜在问题
