Cocos2d-x for Windows Phone 用法總結

本文轉載自查看原文 2014-05-08 15:49 3026 cocos2dx/ cocos2dx移植wp8/ wp8/ cocos2dxwp8

鑒於諾基亞（微軟移動這個沒人用的手機）開發者比較少，cocos2dx移植方面更是少的問題，總結一下WP8移植方面的資料，希望對大家有用，自己也當作筆記留念。

1、WP8方面有兩種方式創建項目，HelloCpp和TestCpp就是這樣，XAML方式和純c++方式。最好選擇xaml方式，因為你有可能會c++和c#進行交互。廢話不說，有圖有真相。

2、說到c++和c#交互，其實叫C++/CX（C++/CX其實是微軟在Win8開發平台下，對C++語言的一種擴展），下面就講述其用法，概念可以去百度。

a) c++調用c#，比如我想獲得該諾基亞的UniqueID，直接上代碼吧，了解c#委托的童鞋應該不難理解，if...baidu...

        WP8DataManager(void)
        {

        }

        {

namespace PhoneDirect3DXamlAppInterop

    public partial class MainPage : PhoneApplicationPage

b) c#調用c++，比如自己添加了一個EditBox和一個Button,通過代碼將EditBox中的值返回給c++中，詳見Demo，我的例子是輸入一個兌換碼然后返回給c++部分

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

//MainPage.xaml.cs
//此處為c#調用，當button按鍵觸發時
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#是用的字符串類型是Platform::String^，需要轉換為std::string。以下的方法可以任意直接轉化，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] = {0};
    MultiByteToWideChar(CP_UTF8, 0, szBuf, -1, wszBuf, sizeof(wszBuf));
    OutputDebugStringW(wszBuf);
    OutputDebugStringW(L"\n");

    WideCharToMultiByte(CP_ACP, 0, 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() + 1;
    wchar_t *_Dest = new wchar_t[_Dsize];
    wmemset(_Dest, 0, _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()));

4、我把WP8DataManager全部貼出來，方便在代碼中直接使用，你可以直接引用到項目的根目錄，如圖。

    public delegate void ToastWP8Delegate(Platform::String^ msg);

    public ref class WP8DataManager sealed
    {
    public:
        WP8DataManager(void)
        {

        }
        ///DeviceInfo
        void SetGetUniqueIDDelegate(GetUniqueIDDelegate^ del)
        {
            m_getUniqueIDDelegate = del;
        }

        Platform::String^ GetUniqueID()
        {            
            if(m_getUniqueIDDelegate)
            {
                return m_getUniqueIDDelegate->Invoke();
            }
            return "";
        }

        void SetToastWP8Delegate(ToastWP8Delegate^ del)
        {
            m_toastWP8Delegate = del;
        }

        void ToastWP8(Platform::String^ msg)
        {
            if(m_toastWP8Delegate)
            {
                m_toastWP8Delegate->Invoke(msg);
            }
        }
        ///DeviceInfo end
