Cocos2d-x for Windows Phone 用法总结，cocos2d-xphone

鉴于诺基亚（微软移动这个没人用的手机）开发者比较少，cocos2dx移植方面更是少的问题，总结一下WP8移植方面的资料，希望对大家有用，自己也当作笔记留念。 

 

1、WP8方面有两种方式创建项目，HelloCpp和TestCpp就是这样，XAML方式和纯c++方式。最好选择xaml方式，因为你有可能会c++和c#进行交互。废话不说，有图有真相。

 

 

 

 

 

2、说到c++和c#交互，其实叫C++/CX（C++/CX其实是微软在Win8开发平台下，对C++语言的一种扩展），下面就讲述其用法，概念可以去百度。

 

    a)  c++调用c#，比如我想获得该诺基亚的UniqueID，直接上代码吧，了解c#委托的童鞋应该不难理解，if...baidu...

//WP8DataManager.h

#ifndef __WP8DataManager_H__

#define __WP8DataManager_H__

namespace PhoneDirect3DXamlAppComponent 

{

    public delegate Platform::String^ GetUniqueIDDelegate();

 

    public ref class WP8DataManager sealed

    {

    public:

        WP8DataManager(void)

        {

 

        }

        ///DeviceInfo

        //此方法将在c#中调用

        void SetGetUniqueIDDelegate(GetUniqueIDDelegate^ del)

        {

            m_getUniqueIDDelegate = del;

        }

        //获得的id,c++直接调用

        Platform::String^ GetUniqueID()

        {            

            if(m_getUniqueIDDelegate)

            {

                return m_getUniqueIDDelegate->Invoke();

            }

            return "";

        }

        ///DeviceInfo end

    private:

        property static GetUniqueIDDelegate^ m_getUniqueIDDelegate;

    };

}

#endif // __WP8DataManager_H__

//MainPage.xaml.cs

{

    public partial class MainPage : PhoneApplicationPage

    {

        // other demo...

        

        //datamanager

        private WP8DataManager m_dataManager = null;

 

        private void DrawingSurface_Loaded(object sender, RoutedEventArgs e)

        {

                m_dataManager.SetGetUniqueIDDelegate(getUniqueID);

    b)  c#调用c++，比如自己添加了一个EditBox和一个Button,通过代码将EditBox中的值返回给c++中，详见Demo，我的例子是输入一个兑换码然后返回给c++部分

 

****************************************************************************

 

//MainPage.xaml.cs

//此处为c#调用，当button按键触发时

m_d3dInterop.OnWP8RedeemResult(WP8RedeemEventType.WP8RedeemSuccess,"110");

 

****************************************************************************

 

//Direct3DInterop.h

void OnWP8RedeemResult(WP8RedeemEventType type,Platform::String^ code);

//Direct3DInterop.cpp

void Direct3DInterop::OnWP8RedeemResult(WP8RedeemEventType type,Platform::String^ code)

{    

    std::lock_guard<std::mutex> guard(mMutex);

    std::shared_ptr<WP8RedeemEvent> e(new WP8RedeemEvent(type,code));

    mInputEvents.push(e);

}

3、通常c#是用的字符串类型是Platform::String^，需要转换为std::string。以下的方法可以任意直接转化，是不是很方便呢

 

 

复制代码

class CC_DLL WP8Tran

    static std::string tranChina(const char * str);

 

    static Platform::String^ tranChinatops(std::string str);

 

    static std::wstring stows(std::string s);

 

    static Platform::String^ stops(std::string s);

 

    static std::string wstos(std::wstring ws);

 

    static std::string pstos(Platform::String^ ps);

};
