我最近成功了。你必须做的事情很少。首先创建帮助类,它将帮助您调用本机函数(我在所有 3 个平台上都使用它,但这里只是 windows phone):
NativeHelper.h:
#ifndef __NATIVE_HELPER_H_
#define __NATIVE_HELPER_H_
#include <string>
#include <functional>
#include "cocos2d.h"
using namespace std;
USING_NS_CC;
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8)
namespace cocos2d
{
public delegate void CSharpShowInterstitialDelegate();
public ref class WP8NativeEventHelper sealed
{
public:
void WP8NativeEventHelper::SetCSharpShowInterstitialDelegate(CSharpShowInterstitialDelegate^ delegate){
m_CSharpShowInterstitialDelegate = delegate;
}
void CallShowInterstitial();
private:
property static CSharpShowInterstitialDelegate^ m_CSharpShowInterstitialDelegate;
};
}
#endif
class NativeHelper
{
public:
static void showInterstitial(string adSdk);
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8)
WP8NativeEventHelper^ wp8helper;
#endif
//instance required only for setting callback
static NativeHelper* getInstance();
~NativeHelper()
{
instanceFlag = false;
}
private:
static bool instanceFlag;
static NativeHelper* instance;
NativeHelper() {};
};
#endif // __NATIVE_HELPER_H_
所以。我们有特殊的 C++/CX 类 Wp8NativeEventHelper,它可以与 C#“对话”。我们在这里存储一个委托。
它是如何工作的:
- C# 正在调用 SetCSharpShowInterstitialDelegate 并向其传递一个委托,该委托将被记住在静态属性中。
- 然后 C++\CX 可以使用 CallShowInterstitial 调用它。
现在 NativeHelperWP.cpp:
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8)
#ifndef __NATIVE_HELPER_WP_H_
#define __NATIVE_HELPER_WP_H_
#include "NativeHelper.h"
void WP8NativeEventHelper::CallShowInterstitial(){
if (m_CSharpShowInterstitialDelegate)
{
m_CSharpShowInterstitialDelegate->Invoke();
}
}
bool NativeHelper::instanceFlag = false;
NativeHelper* NativeHelper::instance = NULL;
NativeHelper* NativeHelper::getInstance()
{
if(!instanceFlag){
instance = new NativeHelper();
instanceFlag = true;
instance->wp8helper = ref new WP8NativeEventHelper();
}
return instance;
}
void NativeHelper::showInterstitial(){
NativeHelper::getInstance()->wp8helper->CallShowInterstitial();
}
#endif
#endif
这里只是 CallShowInterstitial 的一个实现。同样在 NativeHelper::showInterstitial 中,我们调用 C++/CX,后者随后调用 c#。
现在c#代码(MainPage.xaml.cs):
外部命名空间:
using GoogleAds;
课内:
private InterstitialAd interstitialAd;
在构造函数中:
WP8NativeEventHelper helper = new WP8NativeEventHelper();
helper.SetCSharpShowInterstitialDelegate(showInterstitial);
同时创建showInterstitial函数:
public void showInterstitial() //we recreate interstitial each time, because otherwise it'll show only once, only new requests won't work
{
interstitialAd = new InterstitialAd("MY_AD_UNIT_ID");
AdRequest adRequest = new AdRequest();
#if DEBUG
// Enable test ads.
adRequest.ForceTesting = true;
#endif
interstitialAd.ReceivedAd += OnAdReceived;
interstitialAd.LoadAd(adRequest);
}
最后是 OnAdReceived:
private void OnAdReceived(object sender, AdEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Ad received successfully");
interstitialAd.ShowAd();
}
按照本指南设置 admob:https://developers.google.com/mobile-ads-sdk/docs/admob/wp/quick-start
现在让我们使用它。
在 HelloWorldScene.h 中添加:
#include "NativeHelper.h"
在 HelloWorldScene.cpp 中:
NativeHelper::showInterstitial();
例如,您可以显示/隐藏/更改 admob 横幅的位置(但是它有问题,所以我正在使用广告中介)。
