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">

</ClCompile>
<ProjectReference>

</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
