Cocos2d-x for Windows Phone 用法总结

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
namespace PhoneDirect3DXamlAppInterop
{
    public partial class MainPage : PhoneApplicationPage
    {
        // other demo...

        //datamanager
        private WP8DataManager m_dataManager = null;

        private void DrawingSurface_Loaded(object sender, RoutedEventArgs e)
        {
            if (m_d3dInterop == null)
            {
                //demo ......
            }

            if (m_dataManager == null)
            {
                m_dataManager = new WP8DataManager();
                m_dataManager.SetGetUniqueIDDelegate(getUniqueID);
            }
        }

        public String getUniqueID()
        {
            /*try {
                byte[] uniqueIDbytes = (byte[])DeviceExtendedProperties.GetValue("DeviceUniqueId");
                string uniqueID = System.Convert.ToBase64String(uniqueIDbytes);
            }catch(Exception ex){
                MessageBox.Show(ex.Message, "Failed", MessageBoxButton.OK);

            return "abc";
        }
    }
}

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

//your cpp demo
PhoneDirect3DXamlAppComponent::WP8DataManager^ manager = ref new PhoneDirect3DXamlAppComponent::WP8DataManager();
Platform::String^ id = manager->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,"");

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

//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);
}

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

//WP8DataEvent.h
#ifndef __WP8DATA_EVENT__
#define __WP8DATA_EVENT__

#include <agile.h>
#include "../InputEvent.h"

ref class Cocos2dRenderer;

namespace PhoneDirect3DXamlAppComponent
{

public enum class WP8RedeemEventType{
    WP8RedeemFailed,
    WP8RedeemSuccess
};

class WP8RedeemEvent: public InputEvent
{
public:
    WP8RedeemEvent(WP8RedeemEventType type,Platform::String^ code);
    WP8RedeemEvent(WP8RedeemEventType type);

    virtual void execute(Cocos2dRenderer ^ renderer);

private:
    Platform::Agile<Platform::String> m_code;
    WP8RedeemEventType m_type;
};
}
#endif // #ifndef __WP8DATA_EVENT__

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

//WP8DataEvent.cpp
#include "WP8DataEvent.h"
#include "../Cocos2dRenderer.h"

namespace PhoneDirect3DXamlAppComponent
{

WP8RedeemEvent::WP8RedeemEvent(WP8RedeemEventType type,Platform::String^ code)
    :m_type(type),m_code(code)
{

}
WP8RedeemEvent::WP8RedeemEvent(WP8RedeemEventType type)
    :m_type(type)
{

}
void WP8RedeemEvent::execute(Cocos2dRenderer ^ renderer)
{
    switch(m_type)
    {
    case WP8RedeemEventType::WP8RedeemSuccess:
        renderer->nativeRedeemSuccess(m_code.Get());
        break;
    case WP8RedeemEventType::WP8RedeemFailed:
        renderer->nativeRedeemFailed();
        break;
    default:

        break;
    }
}
}

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

//Cocos2dRenderer.h
void nativeRedeemFailed();
void nativeRedeemSuccess(Platform::String^ code);
//Cocos2dRenderer.cpp
void Cocos2dRenderer::nativeRedeemFailed()
{
    //c++ code
    CCLog("nativeRedeemFailed");
}
void Cocos2dRenderer::nativeRedeemSuccess(Platform::String^ code)
{
    //c++ code
    CCLog("nativeRedeemSuccess code=%s",cocos2d::WP8Tran::pstos(code).c_str());
}
****************************************************************************

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

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

NS_CC_BEGIN

class CC_DLL WP8Tran
{
public:
    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);
};

NS_CC_END

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

NS_CC_BEGIN

#define MAX_LEN  (16*1024 + 1)

std::string WP8Tran::tranChina(const char * pszFormat)
{
    char szBuf[MAX_LEN];
    strcpy(szBuf,pszFormat);

    WCHAR wszBuf[MAX_LEN] = {};
    MultiByteToWideChar(CP_UTF8, , szBuf, -, wszBuf, sizeof(wszBuf));
    OutputDebugStringW(wszBuf);
    OutputDebugStringW(L"\n");

    WideCharToMultiByte(CP_ACP, , wszBuf, sizeof(wszBuf), szBuf, sizeof(szBuf), NULL, FALSE);

    return szBuf;
}

Platform::String^ tranChinatops(std::string str)
{
    //return ref new Platform::String(cocos2d::WP8Tran::stows(cocos2d::WP8Tran::tranChina(str.c_str())).c_str());
    return WP8Tran::stops(WP8Tran::tranChina(str.c_str()));
}

std::wstring WP8Tran::stows(std::string str)
{
    setlocale(LC_ALL, "chs");
    const char* _Source = str.c_str();
    size_t _Dsize = str.size() + ;
    wchar_t *_Dest = new wchar_t[_Dsize];
    wmemset(_Dest, , _Dsize);
    mbstowcs(_Dest,_Source,_Dsize);
    std::wstring result = _Dest;
    delete []_Dest;
    setlocale(LC_ALL, "C");
    return result;
}

Platform::String^ WP8Tran::stops(std::string s)
{
    return ref new Platform::String(stows(s).c_str());
}

std::string WP8Tran::wstos(std::wstring ws)
{
    std::string s;
    s.assign(ws.begin(), ws.end());
    return s;
}

std::string WP8Tran::pstos(Platform::String^ ps)
{
    return wstos(std::wstring(ps->Data()));
}

NS_CC_END

4、我把WP8DataManager全部贴出来，方便在代码中直接使用，你可以直接引用到项目的根目录，如图。

        {

            {

            return "";
        }
