Cocos2dx 之 WP8........
记录 cocos2dx wp8下的东西环境是 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);
}
}即可,来源于:http://discuss.cocos2d-x.org/t/wp8-c-call-c-function-with-param/11302/2
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);
#endifMediaStreamer.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 mp3Buffer;// mp3 data stream
std::vector 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, 210, 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
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即可, 内容来自于:http://blogs.msdn.com/b/windows__windows_game_dev_faq_/archive/2014/12/10/mp3-cocos2dx-windows-phone8.aspx
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
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;#if CC_TARGET_PLATFORM == CC_PLATFORM_WP8
theLabel->computeHorizontalKernings(theLabel->_currentUTF16String);
#endif7. 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。
