cocos2d-x开发: 完善接口范例分离模块

在上一篇文章中,我阐述了一下为什么要做分离这种工作,这篇文章没什么重点,只是将上一次没有完善的工作做完.原本我想做到像Lua-tests那样子,能够一次完全显示所有的tests,然后选择要执行的test.可是后来想了一下,没必要做这么多,就简单处理了.不过对于分离处理这个目标是没有偏离的.模块代码部分主要是添加了一个控制和一个接口实现:

 require "src/Tests/TestsRequired"

 TestsController = class("TestsController", nil)
 -----------------------------------------------------------
 -- ctor
 function TestsController:ctor()
     Logger.Info("--------------------------------------------------")
     Logger.Debug("    Running Mode [" .. self.__cname .. "]"            )
 end
 -----------------------------------------------------------
 -- 单例方法
 function TestsController:getInstance()
     if self.instance == nil then
         self.instance = TestsController.new()
     end
     return self.instance
 end
 -----------------------------------------------------------
 -- 运行测试
 function TestsController:runTests()
     --TestsCase.new():run()
 end
 ---------------------------------------------------------------------
 -- End Of Lua File
 ---------------------------------------------------------------------

想要运行test,只需要在runTests方法中运行自己的test就好了.接口实现如下:

  ---------------------------------------------------------------------

  -- @Created on  2014-12-25 20:06
  -- @Brief        测试用例
  ---------------------------------------------------------------------
  TestsCase = class("TestsCase", nil)
  -----------------------------------------------------------
  -- 输出当前测试用例的名字,子类不需要override
  function TestsCase:ctor()
      Logger.Info("---------------------------------------------------")
      Logger.Warn("  Start TestCase [" .. self.__cname .. "]"             )
  end
  -----------------------------------------------------------
  -- 需要子类实现的接口,实现需要的业务逻辑
  function TestsCase:run()
      error("Error: " ..self.__cname.. ":run() method not implemented!")
  end
  ---------------------------------------------------------------------
  -- End Of Lua File
  ---------------------------------------------------------------------

很简单的实现,就需要过多说明什么了,仔细看看extern.lua中class的实现就明白了.我还做了一下额外的工作,也算是对之前写过的代码做了一次修改.不知道怎么回事,看以前写过的代码有的时候会很不爽,禁不住就要做一些修改和重构之类的事情,没办法,这是无药可治的毛病.logger实现,是我在c++部分写的接口,lua这边也做了一点点的封装:

 Logger = {}
 -----------------------------------------------------------

     xy.Logger.Trace(string.format(fmt, ...))
 end
 -----------------------------------------------------------

     xy.Logger.Info(string.format(fmt, ...))
 end
 -----------------------------------------------------------
 -- Debug
 function Logger.Debug(fmt, ...)
     xy.Logger.Debug(string.format(fmt, ...))
 end
 -----------------------------------------------------------
 -- Warn
 function Logger.Warn(fmt, ...)
     xy.Logger.Warn(string.format(fmt, ...))
 end
 -----------------------------------------------------------
 -- Error
 function Logger.Error(fmt, ...)
     xy.Logger.Error(string.format(fmt, ...))
 end
 -----------------------------------------------------------
 -- Fatal
 function Logger.Fatal(fmt, ...)
     xy.Logger.Fatal(string.format(fmt, ...))
 end
 ---------------------------------------------------------------------
 -- End Of Lua File
 ---------------------------------------------------------------------

相应的c++部分的代码是LogUtils.h/LogUtils.cc,我也做了跨平台部分的处理,为了不增加大家的负担,linux部分的处理我就不发出来了.我在opensuse/win7上面都是在使用,所以是没有问题的.代码如下:

 #include "LogUtils.h"
 #include "cocos2d.h"

 #if __cplusplus
 extern "C" {
 #endif
 #include "lualib.h"
 #include "lauxlib.h"
 #if __cplusplus
 }
 #endif
 enum LoggerLevel
 {
     TRACE_, INFO_, DEBUG_, WARN_, ERROR_, FATAL_, NUM_MAX,
 };
 const char* LoggerName[LoggerLevel::NUM_MAX] =
 {
     "[Logger.Trace]", "[Logger.Info ]", "[Logger.Debug]", "[Logger.Warn ]", "[Logger.Error]", "[Logger.Fatal]"
 };
 const std::string getLuastackLogMessage(lua_State* L)
 {
     int nargs = lua_gettop(L);
     std::string logMsg;
     for (int i=; i <= nargs; i++)
     {
         if (lua_istable(L, i))
             logMsg += "table";
         else if (lua_isnone(L, i))
             logMsg += "none";
         else if (lua_isnil(L, i))
             logMsg += "nil";
         else if (lua_isboolean(L, i))
         {
             if (lua_toboolean(L, i) != )
                 logMsg += "true";
             else
                 logMsg += "false";
         }
         else if (lua_isfunction(L, i))
             logMsg += "function";
         else if (lua_islightuserdata(L, i))
             logMsg += "lightuserdata";
         else if (lua_isthread(L, i))
             logMsg += "thread";
         else
         {
             const char * str = lua_tostring(L, i);
             if (str)
                 logMsg += lua_tostring(L, i);
             else
                 logMsg += lua_typename(L, lua_type(L, i));
         }
         if (i!=nargs)
             logMsg += "\t";
     }
     return logMsg;
 }
 #if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
     WORD LoggerColor[LoggerLevel::NUM_MAX] =
     {
         /* intensity */FOREGROUND_INTENSITY,
         /* green     */FOREGROUND_GREEN,
         /* cyan      */FOREGROUND_GREEN|FOREGROUND_BLUE,
         /* yellow    */FOREGROUND_RED|FOREGROUND_GREEN,
         /* red       */FOREGROUND_RED,
         /* red       */FOREGROUND_RED,
     };
     void outputLogMessage(LoggerLevel level, const std::string& logMsg)
     {
         HANDLE hConsole = ::GetStdHandle(STD_OUTPUT_HANDLE);
         if(INVALID_HANDLE_VALUE == hConsole) { return; }
         ::SetConsoleTextAttribute(hConsole, LoggerColor[level]);
         cocos2d::log("%s %s", LoggerName[level], logMsg.c_str());
         ::SetConsoleTextAttribute(hConsole, );
         return;
     }
 #elif (CC_TARGET_PLATFORM == CC_PLATFORM_LINUX)
     void outputLogMessage(LoggerLevel level, const std::string& LogMsg) {}
 #else
     void outputLogMessage(LoggerLevel level, const std::string& LogMsg) {}
 #endif

 #define IMPLEMENTS_LOG_FUNCTION(NAME)        \
     int LogUtil_Logger_##NAME(lua_State* L)                        \
     {                                                            \
         const std::string& logMsg = getLuastackLogMessage(L);    \
         outputLogMessage(LoggerLevel::NAME, logMsg);            \
         return ;                                                \
     }

     IMPLEMENTS_LOG_FUNCTION(TRACE_)
     IMPLEMENTS_LOG_FUNCTION(INFO_)
     IMPLEMENTS_LOG_FUNCTION(DEBUG_)
     IMPLEMENTS_LOG_FUNCTION(WARN_)
     IMPLEMENTS_LOG_FUNCTION(ERROR_)
     IMPLEMENTS_LOG_FUNCTION(FATAL_)

 namespace xy
 {
     const luaL_Reg global_log_functions[] =
     {
         {"Trace", LogUtil_Logger_TRACE_},
         {"Info",  LogUtil_Logger_INFO_},
         {"Debug", LogUtil_Logger_DEBUG_},
         {"Warn",  LogUtil_Logger_WARN_},
         {"Error", LogUtil_Logger_ERROR_},
         {"Fatal", LogUtil_Logger_FATAL_},
         {NULL, NULL},
     };
     void register_xy_LogUtils(lua_State* L)
     {
         luaL_register(L, "xy.Logger", global_log_functions);
     }
 }

这次调整,大概减少了接近五十多行的代码,另外,在结构和代码实行上面也相应要好了很多.这一部分也算是辅助模块的实现了,接下来做通信,资源更新,资源加载策略,加解密,http验证,模块事件,UI封装部分我都会在测试模块做,最后再考虑要着手做一款什么样的游戏来玩玩,这还要看我能找到什么样的资源.最好是ARPG,复杂度会高一点.

这篇没什么,所以就说到这里吧.
