使用C语言写俄罗斯方块

1、我设想的俄罗斯方块如下图： 我们先弹出一个窗口。首先，新建一个windows应用工程，如下图：然后删除工程里预写好的代码，添加如下代码：#include #include HWNDhwnd; /窗口句柄 LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);/声明回调函数char myClassName = myClass;int WINAPI WinMain (HINSTANCE hThisInstance,HINSTANCE hPrevInstance,LPSTR lpszArgument,int nFunsterSti

2、l)MSG messages;WNDCLASSEX wincl;wincl.hInstance = hThisInstance;wincl.lpszClassName = myClassName;/窗口类名wincl.lpfnWndProc = WindowProcedure;/回调函数wincl.style = CS_DBLCLKS;wincl.cbSize = sizeof (WNDCLASSEX);wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);

3、wincl.hCursor = LoadCursor (NULL, IDC_ARROW);wincl.lpszMenuName = NULL;wincl.cbClsExtra = 0;wincl.cbWndExtra = 0; wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;if (!RegisterClassEx (&wincl)/注册窗口类 return 0;hwnd = CreateWindowEx (0,myClassName,俄罗斯方块,WS_OVERLAPPEDWINDOW|WS_VISIBLE,CW_USEDEFAULT,/默认横坐

4、标CW_USEDEFAULT,/默认纵坐标430,615,/长宽 HWND_DESKTOP,NULL,hThisInstance,NULL);while (GetMessage (&messages, NULL, 0, 0)/进入消息循环 TranslateMessage(&messages);DispatchMessage(&messages);return messages.wParam;LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)switch (messag

5、e) case WM_DESTROY:PostQuitMessage (0);break;default:return DefWindowProc (hwnd, message, wParam, lParam);return 0; 然后再点击“编译并运行”按钮，弹出窗口：这样，我们的第一步，就算完成了，呵。以后的我们的所有代码都是在上边代码的基础上添加而成的。如图：上图是一种方块变形的四种情况，为表示以上所有的四的情况，我们需要建立一个三维数组：m_olshapePiece455=0,0,0,0,0,0,0,1,1,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0

6、,0,0,0,0,0,0,0,1,1,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0;上边建立的三维数组应该不难理解吧，m_olshapePiece0xy就表示第一种形状，m_olshapePiece1xy表示第二种形状，m_olshapePiece2xy表示第三种形状，m_olshapePiece3xy表示第四种形状。我们按照同样的方法，把其它几种形状的矩阵弄好，并且把它们设为全局变量，如下：b

7、ool m_longPiece455=0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0;bool m_lshapePiece455=0,0,0,0,0,0,1,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0

8、,0,0,0,1,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,0,0,1,0,0,0,0,0,0,0,0;bool m_olshapePiece455=0,0,0,0,0,0,0,1,1,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,1,1,

9、0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0;bool m_zshapePiece455=0,0,1,0,0,0,1,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,1,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0;bool m_ozshape

11、,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0;bool m_pshapePiece455=0,0,0,0,0,0,0,1,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,0,0,0,1,0,0,0,0,0,0

12、,0,0,0,0,0,0,0,0,1,0,0,0,1,1,0,0,0,0,1,0,0,0,0,0,0,0;接下来，让我们来看仔细看看我们游戏的布局：如上图所示，我们的游戏由五大块组成：一、按钮：这个就是完成一些特定功能的，比如开始、停止、暂停等等，第一个按钮在窗口上的坐标是（12，16）。二、BigMap：它是我们游戏的主要区域，它由二维数组BigMap1221来储存该格子是已有方块，BigMap由DrawBigMap()函数完成在窗口上的绘制。它在窗口上的坐标是（12，66）。三、CurPiece：它是当前正在掉落的方块，它由三维数组CurPiece455来储存，CupPiece是一个5*5

13、的二维平面，但因为它有4种变形，所以我们需要准备4个二维平面。CurPiece由DrawCurPiece()函数完成在窗口上的绘制。它在窗口上的坐标由变量xPos、yPos储存。四、NextPiece：它表示下一个要掉落的方块，它由三维数组NextPiece455来储存，由DrawNextPiece()函数完成在窗口上的绘制。它在窗口上的坐标是（277，66）。五、Score：它表示当前得分和游戏等级，由变量score和level储存（为了方便，我们还需要同时字符串scoreString20和levelString20储存），由DrawScore()函数完成在窗口上的绘制。它在窗口上的坐标分别

14、是（300，220）和（300，270）。或许你对上边的叙述还不太清楚，没关系，随着我们的继续，你会很快明白的。由以上部分可知，我们需要定义的全局变量有：boolBigMap1221;/BigMap boolCurPiece455;/CurPiece boolNextPiece455;/NextPiece intxPos,yPos;/表示当前下落方块在BigMap中的位置坐标 intscore;/储存分数 charscoreString20;/储存分数的字符串 intlevel;/储存过关数 charlevelString20;/储存过关数的字符串 我们需要定义的函数有：void DrawBi

15、gMap();/绘制BigMap void DrawCurMap();/绘制CurPiecevoid DrawNextMap();/绘制NextPiecevoid DrawScore();/绘制Score另外，我们还需要定义的其它全局变量有：HDChdc;/储存设备句柄 HPENhPen;/储存画笔句柄 HBRUSHhBrush;/储存笔刷句柄 intpm=25;/储存一个方块的大小 intdirection;/表示方块当前的方向前三个变量句于绘制。我们说过，正掉落的方块有四种变形，这里我们称之的方块的四种方向，我们用direction储存。pm表示游戏中最小格子的大小，也就是25像素，如下图

16、：我们还需要定义以下几个函数：void init();/初始化变量 void Begin();/按下开始开始按钮时，执行此函数 接下来，我们就开定义以上每个函数，首先是DrawBigMap()函数。BigMap是一个12*21的矩阵，其中有些是用来表示边界的，并不被绘制出来，如下图：其中的灰色部分是边界。其它是0的地方表示该格子没有方块，是1的地方表示该格子有方块，于是DrawBigMap()函数的定义如下：void DrawPiece(int x,int y)/在（x，y）绘制一个大小为pm（25像素）的方块SelectObject (hdc,GetStockObject (WHITE_PE

17、N);/选择白色画笔SelectObject (hdc,GetStockObject (BLACK_BRUSH);/选择黑色笔刷Rectangle(hdc,x,y,x+pm,y+pm);void DrawBigMap()/绘制BigMap SelectObject (hdc,GetStockObject (BLACK_PEN) ;/选择黑色画笔 SelectObject (hdc,GetStockObject (BLACK_BRUSH) ;/选择黑色笔刷 Rectangle(hdc,12,66,12+pm*10,66+pm*20);/先画BigMap黑色矩形背景for(int i=1;i11;

18、i+)for(int j=0;j20;j+)if(BigMapij) /如果该格子为1，则需要画一个方块DrawPiece(12+(i-1)*pm,66+j*pm);其中，函数DrawPiece()函数的功能是在（x，y）绘制一个大小为pm（25像素）的方块，在以后绘制DrawCurPiece()等函数时，我们还会用到它。接下来是DrawCurMap()：void DrawCurMap()/绘制BigMap for(int i=0;i5;i+)for(int j=0;j5;j+)if(CurPiecedirectionij)/如果该格子为1，则需要画一个方块DrawPiece(12+(xPos

19、-1+i)*pm,66+(yPos+j)*pm);其中，全局变量direction表示此时方块处于哪种形状。然后是DrawNextMap()：void DrawNextMap()/绘制NextMapSelectObject (hdc,GetStockObject (BLACK_PEN);/选择黑色画笔 SelectObject (hdc,GetStockObject (BLACK_BRUSH);/选择黑色画笔 Rectangle(hdc,277,66,277+pm*5,66+pm*5);/先画BigMap黑色矩形背景SelectObject (hdc,GetStockObject (WHITE

20、_PEN) ;for(int i=0;i5;i+)for(int j=0;j5;j+)if(NextPiece0ij!=0)/如果该格子为1，则需要画一个方块DrawPiece(277+pm*i,66+pm*j);再然后是DrawScore()：void DrawScore()/绘制ScoreSetBkColor(hdc,RGB(200,200,200);/设置字体的背景色为灰色，以与窗口背景保持一致 TextOut(hdc,300,220,scoreString,strlen(scoreString);/输出分数 TextOut(hdc, 300, 270, levelString,strl

21、en(levelString);/输出过关数 再然后是init()函数：void init()/对BigMap进行初始化 for(int i=0;i12;i+)for(int j=0;j21;j+)if(i=0|i=11|j=20)BigMapij=1;elseBigMapij=0;/对变量初始化 direction=0;score=0;sprintf(scoreString,分数：%d ,score);level=0; sprintf(levelString,级别：%d ,level);xPos=4;yPos=-1;最后是Begin()函数，现在我们的Begin()只是初始化变量：void

22、Begin()init();好了，所有的函数都写好了，以下是全部的代码：#include #include HWNDhwnd; /窗口句柄 bool m_longPiece455=0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0;bool m_lsh

39、tf(levelString,级别：%d ,level);xPos=4;yPos=-1;void Begin()init();编译运行一下，我们看到的窗口如下：我是这样设想游戏主流程的：1、首先设置一个定时器，每次定时到达时，我们就让CurPiece的坐标向下移一位，这样看起来就好像CurPiece正在掉落一样。2、每次CurPiece到达BigMap底部时，我们就把NextPiece的方块复制给CurPiece，然后再把CurPiece的坐标设置在BigMap的最顶端；同时，我们再随机产生一个新方块，并把新方块复制给NextPiece。这样看起来就好像NextPiece开始往下掉一样。那个判

40、断CurPiece是否到达BigMap底部的函数我们用CanDown()函数实现，那个复制的过程我们用CopePiece()函数实现，那个随机产生新方块并复制给NextPiece的过程，我们用NewPiece()函数实现。以下是三个函数的实现：bool CanDown()/判断CurPiece能否继续下落 yPos+;/假设CurPiece下落了 for(int i=0;i5;i+)for(int j=0;j5;j+)if(BigMapxPos+iyPos+j&CurPiecedirectionij)/当有重合的格子都为1时，不能表示表能下落了 yPos-;return false;yPos-

42、(m_olshapePiece,NextPiece);break;case 3:CopePiece(m_zshapePiece,NextPiece);break;case 4:CopePiece(m_ozshapePiece,NextPiece);break;case 5:CopePiece(m_squarePiece,NextPiece);break;case 6:CopePiece(m_pshapePiece,NextPiece);break;CopePiece()和NewPiece()很简单，我们不用说了，我们下边来看下CanDown()是如何判断CurPiece能否继续下落的，看下图：

43、我们先让CurPiece下落一格。如图，当CurPiece和BigMap重合的格子没有都是1的时（图1），CurPiece可以继续往下掉；当CurPiece和BigMap有一个重合的格子都为1时（图2），则不能继续往下掉。这时，CanDown()就差不多应该能看懂了。这时，让我们来进一步完成我的游戏吧。当我们按下“开始”按钮时，我们希望我们游戏就开始了，于是，定时器就需要在Begin()函数里。另外之前做还要做一定的准备工作，比如要给NextPiece和CurPiece赋初值，不然它们会都是0噢：void Begin()init();NewPiece();/随机产生新方块，并复制给NextPi

44、eceCopePiece(NextPiece,CurPiece); /把NextPiece得制给CurPieceNewPiece();/随机产生新方块，并复制给NextPieceSetTimer(hwnd,11,1000,TimerProc);/定时器id为11，时间间隔为1000ms，时间回调函数是TimerProc()也就是说，每1000ms，我们就会执行一下TimerProc()。那么，TimerProc()是怎么样工作的呢？如下：VOID CALLBACK TimerProc (HWND hwnd, UINT message, UINT iTimerID, DWORD dwTime)/

45、定时器回调函数 if(CanDown()/如果能继续下落 yPos+;/则CurPiece下落（纵坐标加1 ） else /如果不能下落 CopePiece(NextPiece,CurPiece); /把NextPiece得制给CurPiecedirection=0;/形状方向初始化为0 xPos=4;/横坐标初始化为4 yPos=-1;/纵坐标初始化为-1 NewPiece();/随机产生新方块，并复制给NextPiece PostMessage(hwnd,WM_PAINT,0,0); /刷新窗口编译运行一下，然后按一下“开始”按钮，呵呵，效果怎么样：我们看到，CurPiece一格格的往下落

46、了，到达底部后，又重新返回到了顶端，并且变成了NextPiece。但我们印象中的俄罗斯方块好像不是这样的，我们更希望看到是，CurPiece在变成NextPiece的同时，老的CurPiece是应该留的BigMap底部的呀！那么老的CurPiece如何才能留在BigMap的底部呢？这个挽留的过程我们用FillBigMap()函数实现，它实际上只是把CurPiece的值填入BigMap而已：void FillBigMap()/将CurPiece填入BigMap for(int i=0;i然后我们把TimerProc()改成下边的样子：VOID CALLBACK TimerProc (HWND hwnd, UINT message, UINT iTimerID, DWORD dwTime)/定时器回调函数 if(CanDown()/如果能继续下落 yPos+;/则CurPiece下落（纵坐标加1 ） else /如果不能下落FillBigMap(); /将CurPiece填入BigMapCopePiece(NextPiece,CurPiece); /把NextPiece得制给CurPiecedirection=0;/形状方向初始化为0 xPos=4;/横坐标初始化为4 yPos=-1;/纵坐标初始化为
