AdMob Interstitial Cocos2d-x WP8

谁能告诉我如何在 cocos2d-x 游戏的场景之间调用 AdMob Interstitial?

我试过这个 http://robwirving.com/2014/07/21/calling-c-methods-c-winrt-components/ 指南,但我不知道如何 运行 它来自 cocos 类。

有没有其他方法,或者一些指南?

我最近做到了。你必须做几件事。首先创建 helper class,它将帮助你调用本地函数(我将它用于所有 3 个平台,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 class Wp8NativeEventHelper,它可以 "talk" 与 C#。这里我们存储一个委托。

工作原理:

  1. C# 正在调用 SetCSharpShowInterstitialDelegate 并将委托传递给它,这将在静态 属性.
  2. 中被记住
  3. 然后C++\CX可以使用CallShowInterstitial来调用它。

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

这里只是一个CallShowInterstitial的实现。同样在 NativeHelper::showInterstitial 中,我们调用 C++/CX,后者稍后调用 c#。

现在的 c# 代码 (MainPage.xaml.cs):

命名空间外:

using GoogleAds;

里面 class:

  private InterstitialAd interstitialAd;

在构造函数中:

WP8NativeEventHelper helper = new WP8NativeEventHelper();
helper.SetCSharpShowInterstitialDelegate(showInterstitial);

并创建 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();
}

按照此指南设置 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,您可以采用相同的方式 show/hide/change admob 横幅的位置(但是它有问题,所以我正在使用广告中介)。
