SimpleCG小游戏开发系列(1)--扫雷

news/2024/2/29 2:48:42

一、前言

        前面我们学习了SimpleCG的游戏开发框架,从本篇开始,我们用一系列小游戏的开发来加深对框架的了解.我们先以windows的经典游戏--扫雷,作为首个例子。游戏预览如下

二、框架搭建

        因为游戏程序的大体框架差不多,所以我们可以搭建一个通用的主程序。如下所示:

// GameMine.cpp : 定义控制台应用程序的入口点。
//#include "../import/include/SimpleCG.h"#define C_IMAGE_WIDTH			640
#define C_IMAGE_HEIGHT			480#ifdef _DEBUG
#pragma comment(lib,"../import/lib/SimpleCG_MDd.lib")
#else
#ifdef _WIN64
#pragma comment(lib,"../import/lib/x64/MTRelease/SimpleCG_MT64.lib")
#else
#pragma comment(lib,"../import/lib/SimpleCG_MT.lib")
#endif
#endifLRESULT OnKeyDown(HWND hWnd, WPARAM wParam, LPARAM lParam);//绘制游戏
void RenderGame()
{}
//更新游戏状态
void UpdateGame( UINT nElapse )
{static int s_nLastTick = 0;if( ( nElapse - s_nLastTick )<120 )return;s_nLastTick = nElapse;}
//按键消息响应函数
LRESULT OnKeyDown(HWND hWnd, WPARAM wParam, LPARAM lParam)
{switch( wParam ){case VK_SPACE:break;case VK_UP:break;case VK_DOWN:break;case VK_LEFT:break;case VK_RIGHT:break;}return 0;
}
LRESULT OnLButtonDown( HWND hWnd, WPARAM wParam, int nX, int nY )
{return false;
}
LRESULT OnLButtonUp( HWND hWnd, WPARAM wParam, int nX, int nY )
{return false;
}
LRESULT OnRButtonDown( HWND hWnd, WPARAM wParam, int nX, int nY )
{return false;
}
LRESULT OnRButtonUp( HWND hWnd, WPARAM wParam, int nX, int nY )
{return false;
}
LRESULT OnMouseMove( HWND hWnd, WPARAM wParam, int nX, int nY )
{return false;
}
//初始化游戏
void InitGame(HWND hWnd)
{int i=0;int j=0;srand(GetTickCount());GetKeyboardInput()->onKeyDown		= OnKeyDown;GetMouseInput()->onMouseDownLeft	= OnLButtonDown;GetMouseInput()->onMouseDownRight	= OnRButtonDown;GetMouseInput()->onMouseUpLeft		= OnLButtonUp;GetMouseInput()->onMouseUpRight		= OnRButtonUp;GetMouseInput()->onMouseMove		= OnMouseMove;
}int _tmain(int argc, _TCHAR* argv[])
{SCG_GameLoopInfo info;info.nFPS				= 60;info.nHeight			= C_IMAGE_BLOCK*g_nMapHeight+C_IMAGE_BLOCK;//C_IMAGE_HEIGHT;info.nWidth				= C_IMAGE_BLOCK*g_nMapWidth;//C_IMAGE_WIDTH;info.pFunDrawProcess	= RenderGame;info.pFunFrameUpdate	= UpdateGame;info.pFunInitGame		= InitGame;info.pFunInput			= NULL;if( !StartGameLoopEx( &info ))return 1;return 0;
}

        这个框架基本上就是前面文章所介绍的游戏开发框架。然后有了这个主框架,我们根据我们要开发的扫雷游戏,我们分别建立游戏逻辑的实现文件mine.cpp,以及头文件mine.h文件。在这两个文件中我们实现扫雷的相关逻辑,然后再把相关代码接入主程序即可。

三、游戏逻辑实现mine.cpp及mine.h文件

mine.h头文件

}

四、逻辑接入主程序

在主程序中做以下几个修改,就将扫雷的逻辑接入主程序并将画面展现出来,同时接收用户的输入操作并反应。首先当然是包含逻辑头文件Mine.h

#include "Mine.h"

然后绘制画面

//绘制游戏
void RenderGame()
{setbackmode(enumBKM_TRANSPARENT);DrawMap();setbackmode(enumBKM_OPAQUE);//绘制界面DrawUI(  );
}

我们没有在更新函数中做任何更新,所以不需要改变UpdateGame

然后在鼠标输入操作中,我们需要判断是否在地图上并根据输入进行状态改变


LRESULT OnLButtonDown( HWND hWnd, WPARAM wParam, int nX, int nY )
{if( IsOnMap(nX,nY))return MapOnLButtonDown( wParam, nX, nY );return false;
}
LRESULT OnLButtonUp( HWND hWnd, WPARAM wParam, int nX, int nY )
{if( IsOnMap(nX,nY))return MapOnLButtonUp( wParam, nX, nY );return false;
}
LRESULT OnRButtonDown( HWND hWnd, WPARAM wParam, int nX, int nY )
{if( IsOnMap(nX,nY))return MapOnRButtonDown( wParam, nX, nY );return false;
}
LRESULT OnRButtonUp( HWND hWnd, WPARAM wParam, int nX, int nY )
{if( IsOnMap(nX,nY))return MapOnRButtonUp( wParam, nX, nY );return false;
}
LRESULT OnMouseMove( HWND hWnd, WPARAM wParam, int nX, int nY )
{if( IsOnMap(nX,nY))return MapOnMouseMove( wParam, nX, nY );return false;
}

最后在初始化阶段进行游戏初始化即可,此处初始化10个炸弹,9x9地图

Init( 10, 9, 9 );

四、代码下载

所有代码可在以下地址察看或下载,

gamemine · master · b2b160 / SimpleCG_Demo · GitCode

编译此程序需安装SimpleCG库,安装方法如下:
