什么是热更新？
游戏客户端启动时，主动请求服务端检查版本号，并更新资源到本地。
应用场景：
情况一：游戏客户端已经发布了，但突然发现有个比较严重的bug需要修复。这时需要更新游戏的代码（Lua代码）。
情况二：情人节到了，需要搞个活动，在游戏中营造一个节日氛围。这时，需要更新游戏资源或增加一些功能。
好处：不需要重新打包和提交应用到市场等待审核。
在Cocos2d-x中已经封装了用于实现热更新功能的类，就是AssetsManager。
api说明：
// 检测是否有版本更新
virtual bool checkUpdate();
// 下载更新的资源包并解压到下载路径
virtual void update();
// 获取当前客户端版本号
std::string getVersion();
// 删除客户端版本号
void deleteVersion();
// 设置下载回调（AssetsManagerDelegateProtocol）
void setDelegate(AssetsManagerDelegateProtocol *delegate);
// 设置连接超时时间（单位：秒）
void setConnectionTimeout(unsigned int timeout);
// 设置从服务端下载资源包的url
void setPackageUrl(const char* packageUrl);
// 设置服务端获取版本号的url
void setVersionFileUrl(const char* versionFileUrl);
// 设置资源保存路径
void setStoragePath(const char* storagePath);
因为AssetsManager使用了pthread库，所以需要在win32工程中需要包含pthread库所在目录。
VS在工程属性——C/C++——常规——附加包含目录中添加：$(ProjectDir)..\..\..\cocos2dx\platform\third_party\win32\pthread
该工程使用Cocos2d-x2.1.6和VS2012。【点击下载源码】
把工程放到引擎projects目录下即可。

热更新介绍
什么是热更新？游戏客户端启动时，主动请求服务端检查版本号，并更新资源到本地。
应用场景：
情况一：游戏客户端已经发布了，但突然发现有个比较严重的bug需要修复。这时需要更新游戏的代码（Lua代码）。
情况二：情人节到了，需要搞个活动，在游戏中营造一个节日氛围。这时，需要更新游戏资源或增加一些功能。
好处：不需要重新打包和提交应用到市场等待审核。
热更新流程
AssetsManager
在Cocos2d-x中已经封装了用于实现热更新功能的类，就是AssetsManager。api说明：
// 检测是否有版本更新
virtual bool checkUpdate();
// 下载更新的资源包并解压到下载路径
virtual void update();
// 获取当前客户端版本号
std::string getVersion();
// 删除客户端版本号
void deleteVersion();
// 设置下载回调（AssetsManagerDelegateProtocol）
void setDelegate(AssetsManagerDelegateProtocol *delegate);
// 设置连接超时时间（单位：秒）
void setConnectionTimeout(unsigned int timeout);
// 设置从服务端下载资源包的url
void setPackageUrl(const char* packageUrl);
// 设置服务端获取版本号的url
void setVersionFileUrl(const char* versionFileUrl);
// 设置资源保存路径
void setStoragePath(const char* storagePath);
因为AssetsManager使用了pthread库，所以需要在win32工程中需要包含pthread库所在目录。
VS在工程属性——C/C++——常规——附加包含目录中添加：$(ProjectDir)..\..\..\cocos2dx\platform\third_party\win32\pthread
示例工程
该工程使用Cocos2d-x2.1.6和VS2012。【点击下载源码】把工程放到引擎projects目录下即可。
