 HGE游戏引擎是一个开源2D游戏引擎，基于directX。

它的渲染及逻辑是基于帧回调的框架模式，

其提供一些基本的图像操作和输入控制功能。

 

我在之前写一个2D游戏的时候对它整个框架进行了一次封装，很多地方写得比较恶心，请原谅我在变量上命名的不规范。

 

在此分享出来，主要可以参考一下大体框架吧。

 

HGE游戏引擎基于帧的回调让我很不爽，因为咱的游戏逻辑一般是连续的，跟具体帧无关，所以我把整个HGE跑在自己的一个线程之中。我的游戏逻辑部分通过发消息，通知界面更新 以及获取用户输入。

 在HGE的主框架下分四个部分

1. 资源管理 2.消息管理 3.声音管理 4.UI管理

 

下面是GDE_UI_HGEFramework.h

比较核心的是资源管理类，下面给出

GDE_UI_ResourceManager.h

       namespace GDE {
   namespace GDE_UI {
   //资源管理类 class ResourceManager {

GDE_UI_ResourceManager.cpp

 

1 #include "GDE_UI_HGEFramework.h"  2 #include "GDE_UI_ResourceManager.h"  3  4 namespace  5 {
    6     std::string const RES_MANAGER_FILENAME = "res/res_s";  7     int const WIN_SCREENWIDTH        = 800;  8     int const WIN_SCREENHEIGHT        = 600;  9     std::string const WIN_TITILE    = "HGE TEST WINDOW"; 10     int const WIN_COLORMODE            = 32; 11     int const WIN_MAXFPS            = 100; 12     int const WIN_WINDOWED            = true; 13 14 } 15 16 namespace GDE 17 {
   18 namespace GDE_UI 19 {
   20 21 //构造函数 22 ResourceManager::ResourceManager() 23     : m_HgeResManager( RES_MANAGER_FILENAME.c_str() ) 24 {
   25     //建立HGE全局实例 26     pHGE = hgeCreate(HGE_VERSION); 27 28     //初始化配置 29     pHGE->System_SetState(HGE_INIFILE, "hgedemo.ini"); 30     pHGE->System_SetState(HGE_LOGFILE, "hgedemo.log"); 31     pHGE->System_SetState(HGE_FRAMEFUNC, &HGE_Framework::FrameFunc); 32     pHGE->System_SetState(HGE_RENDERFUNC, &HGE_Framework::RenderFunc); 33     pHGE->System_SetState(HGE_TITLE, WIN_TITILE.c_str()); 34     pHGE->System_SetState(HGE_SCREENWIDTH, WIN_SCREENWIDTH); 35     pHGE->System_SetState(HGE_SCREENHEIGHT, WIN_SCREENHEIGHT); 36     pHGE->System_SetState(HGE_SCREENBPP, WIN_COLORMODE); 37     pHGE->System_SetState(HGE_FPS,WIN_MAXFPS); 38     pHGE->System_SetState(HGE_WINDOWED, WIN_WINDOWED); 39     pHGE->System_SetState(HGE_HIDEMOUSE, false); 40     pHGE->System_SetState(HGE_USESOUND, false); 41     pHGE->System_SetState(HGE_DONTSUSPEND, true);//失去焦点不挂起 42     pHGE->System_SetState((hgeIntState)14, (int)0xFACE0FF); //禁用HGE LOGO 43 44 //初始化GUI 45     pGUI = new hgeGUI(); 46     pGUI->SetNavMode(HGEGUI_UPDOWN | HGEGUI_CYCLED); 47     pGUI->Enter(); 48 } 49 50 ResourceManager::~ResourceManager() 51 {
   52     // 销毁gui 53     delete pGUI; 54 55     // 销毁资源管理器 56     m_HgeResManager.Purge(); 57 58     // HGE结束 59     pHGE->System_Shutdown(); 60     pHGE->Release(); 61 } 62 63 void ResourceManager::LoadImage( std::string const& filename, hgeSprite*& p_sprite, HTEXTURE& tex ) 64 {
   65     if( p_sprite ) 66         delete p_sprite; //销毁之前的图片 67 68     tex = pHGE->Texture_Load( filename.c_str() ); //装载纹理 69     int w = pHGE->Texture_GetWidth( tex ); 70     int h = pHGE->Texture_GetHeight( tex ); 71     p_sprite = new hgeSprite( tex, 0, 0, w, h ); //剪裁精灵 72 } 73 74 75 } 76 }

比较重要的是消息传递机制，我仿照了MFC的消息宏定义机制，下面给出消息模块的核心代码

 

1 //消息映射宏定义  2 #define BEGIN_MESSAGE_MAP()/  3     typedef void (MessageManager::*MessageFunction)();/  4     std::map
     
       message_functions_;/  5     void InitMessageMap()/  6     {
    7 #define ON_MESSAGE( ID, memberFuc )/  8     message_functions_[ID] = &MessageManager::memberFuc;  9 #define END_MESSAGE_MAP/ 10     } 11 12 13 14 .... 15 16 17 18 //这里是我游戏中具体的一些消息 19 20 //消息类型 21 typedef int UIMessage; 22 23 UIMessage const UIMessage_UpdateBackImg  = 0; //更新背景图片 24 25 UIMessage const UIMessage_AddRole         = 10; //增加角色 26 UIMessage const UIMessage_RemoveRole     = 11; //删除角色 27 UIMessage const UIMessage_UpdateRole     = 12; //更新角色列表 28 UIMessage const UIMessage_AttackInfo     = 13; //角色掉血显示 29 30 UIMessage const UIMessage_UpdateDialog     = 20; //更新对话框 31 UIMessage const UIMessage_HideDialog      = 21; //隐藏对话框 32 33 UIMessage const UIMessage_UpdateSmallMap = 30; //更新小地图 34 35 UIMessage const UIMessage_UpdateGameInfo = 40; //更新游戏提示信息 36 37 UIMessage const UIMessage_UpdateButton     = 50; //增加按钮 38 UIMessage const UIMessage_RemoveButton     = 51; //删除按钮 39 UIMessage const UIMessage_RemoveAllButtons    = 52; //移除所有按钮 40 41 UIMessage const UIMessage_UpdatePopMenu     = 60; //弹出菜单 42 UIMessage const UIMessage_HidePopMenu     = 61; //隐藏弹出菜单 43 44 UIMessage const UIMessage_UpdateZoneBlock= 70; //更新地图块 45 UIMessage const UIMessage_HideZoneBlock  = 71; //清除地图块 46 47 48 //消息映射实现 49 50 BEGIN_MESSAGE_MAP() 51     ON_MESSAGE( UIMessage_UpdateBackImg, UpdateBackImage ) 52     ON_MESSAGE( UIMessage_AddRole, AddRole ) 53     ON_MESSAGE( UIMessage_RemoveRole, RemoveRole ) 54     ON_MESSAGE( UIMessage_UpdateRole, UpdateRole ) 55     ON_MESSAGE( UIMessage_AttackInfo, RoleAttackInfo ) 56     ON_MESSAGE( UIMessage_UpdateDialog, UpdateDialog ) 57     ON_MESSAGE( UIMessage_HideDialog, HideDialog ) 58     ON_MESSAGE( UIMessage_UpdateSmallMap, UpdateSmallMap ) 59     ON_MESSAGE( UIMessage_UpdateGameInfo, UpdateGameInfo ) 60     ON_MESSAGE( UIMessage_UpdateButton, UpdateButton ) 61     ON_MESSAGE( UIMessage_RemoveButton, RemoveButton ) 62     ON_MESSAGE( UIMessage_RemoveAllButtons, RemoveAllButtons ) 63     ON_MESSAGE( UIMessage_UpdatePopMenu, UpdatePopMenu ) 64     ON_MESSAGE( UIMessage_HidePopMenu, HidePopMenu ) 65     ON_MESSAGE( UIMessage_UpdateZoneBlock, UpdateZoneBlock ) 66     ON_MESSAGE( UIMessage_HideZoneBlock, HideZoneBlock ) 67 END_MESSAGE_MAP() 68 69 70     //处理消息 71     void ProcessMessage() 72     {
   73         for( int i = 0; i < m_MessageList.size(); ++i ) 74         {
   75             ( this->*message_functions_[m_MessageList[i]] )(); 76         } 77         m_MessageList.clear(); 78     }
     

最后是整个HGE引擎启动的方式

GDE_UI_HGE.h

 

1 #ifndef GDE_UI_HGE_H_  2 #define GDE_UI_HGE_H_  3  4 #include 
     
        5 #include 
      
         6  7 #include "GDE_UI_HGEFramework.h"  8  9 /* 10 GDE HGE游戏引擎模块 2009-11-21 11 12 var | author | brief 13 ================================================ 14 1.0   cg       create 15 */ 16 17 namespace GDE 18 {
   19 namespace GDE_UI 20 {
   21 22 //HGE线程入口 23 static DWORD WINAPI HGEThreadProc(LPVOID lpParameter) 24 {
   25     HGE_Framework::Instance()->Run(); 26     return 0; 27 } 28 29 } 30 } 31 #endif
      
     

游戏初始化的时候   

 

//创建hge线程

  hge_thread = CreateThread( NULL, 0, 

   HGEThreadProc, NULL, 0, NULL );

 

就可以了
