Cocos2dx 之 WP8........

<span style="font-family: Arial,Helvetica,sans-serif; background-color: rgb(255,255,255);">记录 cocos2dx wp8下的东西</span>

环境是 cocos2dx 3.2 vs2013

1. wp8下的内购

C++ 调用 WP8 api(相当于C++调用C#)

a.进行设置wp8内购相关信息

1.先提交一个beta应用,并且添加测试人员的的测试帐号,因为只有测试帐号才能进行下载

2. 添加内购项目,记录下每一个item的 id

3.一般提交后2小时左右就能得到程序的下载地址，使用测试人员帐号下载该程序进行购买

关于 IAP设置和测试的基本过程大致就是这样

b. 修改项目的相关属性

WMAppManifest.xml-->打包,填写相应的产品ID和发布者ID

c. 添加代码进行实现

1.添加 WP8Util.h .cpp

#ifndef __WP8UTIL__
#define  __WP8UTIL__

// c++ to call C# 
#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8

// can not change namespace
namespace PhoneDirect3DXamlAppComponent{

	[Windows::Foundation::Metadata::WebHostHidden]
	public interface class IWP8Callback{
		virtual void Exec(Platform::String ^Command,Platform::String ^Param);
	};


	public ref class WP8Util sealed{
	public:
		static void SetWP8UtilCallback(IWP8Callback^ callback);
		static void  buy();
		static void rank();
		static void submit();
	};
}

#endif


#endif // !__WP8UTIL__

#include "WP8Util.h"
#include "cocos2d.h"
using namespace cocos2d;

#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
namespace PhoneDirect3DXamlAppComponent{

	static IWP8Callback^ gWp8Callback = nullptr;

	void  WP8Util::buy(){
		if (gWp8Callback != nullptr)
		{
			log("WP8Util::buy  clicked......");
		}
	}
	void WP8Util::rank(){
		if (gWp8Callback != nullptr)
		{
		}
	}

	void WP8Util::submit(){
		if (gWp8Callback != nullptr)
		{
		}
	}

	void WP8Util::SetWP8UtilCallback(IWP8Callback^ callback){
		gWp8Callback = callback;
		log("------>>>>>>>>>>>>>>>>>>>>>Regist IWP8Callback");
	}
}
#endif

主要流程就是在 WP8 C# 端进行实现 IWP8Callback,设置 IWP8Callback.

在IWP8Callback的方法里面根据相应的命令去完成相应C#方法的调用.

在 MainPage.xaml.cs 文件里面添加:

1. using PhoneDirect3DXamlAppComponent;

2. 添加：

 /// IWP8Callback 
    public class WP8CallbackImpl : IWP8Callback {
        public WP8CallbackImpl() {
            WP8Util.SetWP8UtilCallback(this);
        }

        public void Exec(String Command,String Param) {
            //Execute some C# code,if you call UI stuff you will need to call this too
            /*Deployment.Current.Dispatcher.BeginInvoke(() =>
            {
            });*/
            Debug.WriteLine("C# method---" + Command + "-----" + Param);
        }
    }

2.wp8 下播放 mp3

默认 wp8 不支持 .mp3文件,为了和 ios/Android 统一,使其支持.mp3文件格式的播放

a. 下载代码

https://github.com/tianjing/lame_wp8

b.将libmp3lame,libmpghip,src三个文件夹拷贝到Cocos2dx的proj.wp8-xaml目录下

然后添加 lib3lame和libmpghip这两个项目到解决方案里面

c.让Cocos2dx wp8的 XXXComponent 项目添加libmp3lame,libmpghip这两个项目的引用

d.在CocosDenshion项目属性中->VC++目录->包含目录中添加 "lame.h"文件所在的文件夹

e.修改CocosDenshion下部分代码

MediaStreamer.h 里面添加

	// for wp8 add new method
#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
	void Initialize_MP3(_In_ const WCHAR* url);
#endif

MediaStreamer.cpp 里面添加实现的方法

#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
void MediaStreamer::Initialize_MP3(_In_ const WCHAR* url){
#if 1
	WCHAR filePath[MAX_PATH] = { 0 };
	if ((wcslen(url) > 1 && url[1] == ':'))
	{
		// path start with "x:",is absolute path
		wcscat_s(filePath,url);
	}
	else if(wcslen(url) > 0
		&& (L'/' == url[0] || L'\\' == url[0]))
	{
		// path start with '/' or '\',is absolute path without driver name
		wcscat_s(filePath,m_locationPath->Data());
		// remove '/' or '\\'
		wcscat_s(filePath,(const WCHAR*)url[1]);
	}
	else
	{
		wcscat_s(filePath,m_locationPath->Data());
		wcscat_s(filePath,url);
	}


	hip_t hip = hip_decode_init();
	if (!hip)
	{
		printf("create mp3 decoder Failed.");
		return;
	}

	mp3data_struct mp3str;//mp3 encoding info
	std::vector<short*> mp3Buffer;// mp3 data stream
	std::vector<int> mp3BufferSize;

	int samples;
	int mp3_bytes;
	int write_bytes = 0;

	const int BUF_SIZE = 512;
	const int INBUF_SIZE = 4096;
	const int MP3BUF_SIZE = (int)(1.25 * BUF_SIZE) + 7200;

	short pcm_l[INBUF_SIZE];
	short pcm_r[INBUF_SIZE];
	unsigned char mp3_buf[MP3BUF_SIZE];

	FILE * MP3File;


	std::wstring wstr = std::wstring(filePath);

	std::string str_filePath = std::string(wstr.begin(),wstr.end());


	auto error = fopen_s(&MP3File,str_filePath.c_str(),"rb");
	mp3data_struct mp3Header;

	while ((mp3_bytes = fread(mp3_buf,1,210,MP3File)) > 0)
	{
		samples = hip_decode_headers(hip,mp3_buf,pcm_l,pcm_r,&mp3Header);
		if (samples > 0)
		{
			short *tt = new short[samples*sizeof(short)];
			memcpy((void*)tt,(const void*)pcm_l,samples*sizeof(short));
			mp3Buffer.push_back(tt);
			write_bytes += samples*sizeof(short);
			mp3BufferSize.push_back(samples*sizeof(short));
		}
	}


	byte* _mp3Buffer = new byte[write_bytes];
	byte* temp = _mp3Buffer;
	int size = mp3BufferSize.size();
	for (int i = 0; i < size; i++)
	{
		memcpy(temp,mp3Buffer[i],mp3BufferSize[i]);
		delete mp3Buffer[i];
		temp += mp3BufferSize[i];
	}
	mp3Buffer.clear();
	hip_decode_exit(hip);

	m_data.resize(write_bytes);
	for (int i = 0; i < write_bytes; i++)
	{
		m_data[i] = _mp3Buffer[i];
	}

	fclose(MP3File);

	m_waveFormat.wFormatTag = WAVE_FORMAT_PCM; //
	m_waveFormat.nChannels = 1; //
	m_waveFormat.nSamplesPerSec = (DWORD)mp3Header.samplerate;// 

	m_waveFormat.wBitsPerSample = 16;
	m_waveFormat.nBlockAlign = m_waveFormat.nChannels * m_waveFormat.wBitsPerSample / 8.0;
	m_waveFormat.nAvgBytesPerSec = m_waveFormat.nSamplesPerSec * m_waveFormat.nBlockAlign; //
	m_waveFormat.cbSize = 0;

	delete[] _mp3Buffer;
#endif
}
#endif

修改 Audio.cpp的 PreloadSoundEffect方法.

将

<span style="white-space:pre">	</span>mediaStreamer.Initialize(CCUtf8ToUnicode(pszFilePath).c_str());

替换成:

#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
	// add .mp3 decode in wp8
	std::string path(pszFilePath);
	std::string::size_type pos = path.find(".mp3");
	if (pos != path.npos)
	{
		mediaStreamer.Initialize_MP3(CCUtf8ToUnicode(pszFilePath).c_str());
	}
	else
	{
		mediaStreamer.Initialize(CCUtf8ToUnicode(pszFilePath).c_str());
	}
#else
	mediaStreamer.Initialize(CCUtf8ToUnicode(pszFilePath).c_str());
#endif

3.wp8 下使用sqlite3

a.在 VS2013-->工具-->扩展和更新里面下载使用于 windows phone 8.0的 sqlite

b.在项目里面XXXComponent -->属性通用属性-->引用-->添加新引用-->扩展里面,选择 winodws phone sqlite

c.在项目里面XXXComponent -->属性-->链接器-->输入-->附加依赖项目,加上

C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v8.0\ExtensionSDKs\sqlite.WP80\3.8.9\DesignTime\Retail\ARM\sqlite3.lib
c.基本就可以正常使用sqlite了

4. wp8下添加广告

a.c# wp8 工程下 add reference -> google admob

b. 到 MainPage.xaml 下添加 AdControl

 <GoogleAds:AdView AdUnitID="ca-app-pub-9565466250630588/6418716150"
                          Format="Banner"
                          ReceivedAd="onAdReceived"
                          FailedToReceiveAd="onFailedToReceived"
                          x:Name="adView"
                          VerticalAlignment="Bottom" />

c. 在 MainPage.xaml.cs里添加方法

(见demo)

5. wp8下中文显示

6. wp8跳转到内购后,点击取消返回到游戏时,游戏 Crash,在LabelTextFormatter.cpp中

LabelTextFormatter::createStringSprites方法里面

 const auto& kernings = theLabel->_horizontalKernings;

前面加上:

#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
	theLabel->computeHorizontalKernings(theLabel->_currentUTF16String);
#endif

7. wp8 上传时出现

1028: 程序集 XXXXComponent.dll 中不允许本机 API MSVCP110D.dll 请更新该程序集，然后重试。

类似这样的情况,

解决步骤 1. 设置成 Device --- Release

2. 项目-->属性-->调试-->UI任务设置成仅限托管

3. CocosDenshion里面,将 Audio.h 里面的 CreateEventEx 换成 CreateEventExW

~~8. 将 mac下 utf8 文件存储为 utf8 带签名文件,方便在 VS下打开~~

<del># 将 文件存储为UTF8带BOM
import os
import sys

rpath = "/Users/mac/work/cocos2d-x-3.2/projects/Bubble/Classes_2/"
tpath = "/Users/mac/Desktop/MyClasses/"

for file in os.listdir("/Users/mac/work/cocos2d-x-3.2/projects/Bubble/Classes_2"):
 	if file[0] != '.':
 		f = open(rpath + str(file))
 		s = f.read()
 		f.close()

 		u = s.decode("utf8")
 		f = open(tpath+str(file),"w")
 		#编码成utf8带签名
 		s = u.encode("utf-8-sig")
 		f.write(s)
 		f.close()


print "-------处理完毕-------------"</del>
