Cocos2d-x for Windows Phone 用法总结
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...
复制代码
****************************************************************************
//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,"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);
}
****************************************************************************
//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
复制代码

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);
};
