“贪吃蛇”游戏程序代码

“贪吃蛇”游戏程序代码我个人是比较喜欢玩游戏的，所以学习编程二年多了，很想做个游戏程序，由于能力有限，一直没能做好，后来突然看同学在手机上玩“贪吃蛇”，故想做出来，其一是因为此游戏界面容易设计，算法也比较简单，今天我就把我程序的代码和算法介绍一下，顺便把程序界面皮肤设计说一下......

程序中一个关于游戏信息的类如下，由于类的说明在程序中写的很清楚了，就不再多解释了：#include"time.h"

//方向定义

constCPointUP(CPoint(0,-1));

constCPointDOWN(CPoint(0,1));

constCPointLEFT(CPoint(-1,0));

constCPointRIGHT(CPoint(1,0));

//速度快慢定义

constintHIGH=75;

constintNORMAL=180;

constintSLOW=300;

constintMAX=80;//表示转向数

constintLENGTH=10;

classGameMsg

{

public:

GameMsg(void)

:m_icon(0)

{

InitGame();

}

voidInitGame(intup=VK_UP,intdown=VK_DOWN,intleft=VK_LEFT,intright=VK_RIGHT)

{

srand((unsigned)time(NULL));

m_gameSpeed=NORMAL;

m_speedNum=2;

m_snakeNum=4;

for(inti=0;i<m_snakeNum;++i)

m_snakePoint[i]=CPoint(5+LENGTH*2*5+LENGTH,LENGTH*2*(i+5));

m_run=true;

m_direction=RIGHT;

turnUP=up;

turnDOWN=down;

turnLEFT=left;

turnRIGHT=right;

}

public:

intm_gameSpeed;//游戏速度

intm_speedNum;//游戏速度数

CPointm_foodPoint;//食物定义

boolm_run;//游戏状态，运得态还是暂停（结束）态

CPointm_snakePoint[MAX];//蛇身定义

CPointm_direction;//蛇运动方向

CFontm_font;//这就是上图中显示“空心字体”的字体设置voidShowHollowFont(intcx,intcy,CStringstr);//显示空心字体函数，在（Cx，Cy）处显示字符串str

afx_msgvoidOnBnClickedExit();//退出游戏

private:

intm_icon1;//表明蛇吃第1种水果的个数

intm_icon2;//表明蛇吃第2种水果的个数

intm_icon3;//表明蛇吃第3种水果的个数然后给读者写的是我程序运行很重要的一个函数，WM_TIMER显示函数，里面有食物位置随机出现，判断蛇死，蛇移动等：

voidCSnakeDlg::OnTimer(UINT_PTRnIDEvent)

{

if(game.m_snakePoint[0].x<0||game.m_snakePoint[0].y<LENGTH||game.m_snakePoint[0].x>700||game.m_snakePoint[0].y>500)//当蛇跑出边界,游戏结束

{

GameOver();

}

for(intj=game.m_snakeNum-1;j>0;--j)//蛇移动的量的变化，当重新设定这些控件的位置时也就是让蛇移动起来game.m_snakePoint[j]=game.m_snakePoint[j-1];

game.m_snakePoint[0].x+=game.m_direction.x*LENGTH*2;//蛇头移动game.m_snakePoint[0].y+=game.m_direction.y*LENGTH*2;

for(inti=0;i<game.m_snakeNum;++i)

{

m_staticArray[i].SetWindowPos(NULL,game.m_snakePoint[i].x-LENGTH,game.m_snakePoint[i].y-LENGTH,game.m_snakePoint[i].x+LENGTH,game.m_snakePoint[i].y+LENGTH,

SW_SHOW);

}

for(intj=1;j<game.m_snakeNum;++j)//当蛇撞到自己也结束游戏if(game.m_snakePoint[0]==game.m_snakePoint[j])

{

GameOver();

}

m_staticArray[MAX].ModifyStyle(0xF,SS_ICON|SS_CENTERIMAGE);//显示水果m_staticArray[MAX].SetIcon(AfxGetApp()->LoadIcon(game.m_icon));

m_staticArray[MAX].SetWindowPos(NULL,game.m_foodPoint.x,game.m_foodPoint.y,32,32,

SW_SHOW);

//当蛇吃到水果

if(game.m_snakePoint[0].x<game.m_foodPoint.x+20+LENGTH&&game.m_snakePoint[0].x>game.m_foodPoint.x-LENGTH&&game.m_snakePoint[0].y<game.m_foodPoint.y+20+LENGTH&&game.m_snakePoint[0].y>game.m_foodPoint.y-LENGTH)

{

game.m_foodPoint=CPoint(LENGTH*game.RandNum(2,37),LENGTH*game.RandNum(2,27));

CStringstr;

if(game.m_num==0)

{

++m_icon1;

str.Format("%d",m_icon1);

GetDlgItem(IDC_EDIT1)->SetWindowTextA(str);

}

elseif(game.m_num==1)

{

++m_icon2;

str.Format("%d",m_icon2);

GetDlgItem(IDC_EDIT2)->SetWindowTextA(str);

}

else

{

++m_icon3;

str.Format("%d",m_icon3);

GetDlgItem(IDC_EDIT3)->SetWindowTextA(str);

}

game.m_num=game.RandNum(0,3);

game.m_icon=IDI_ICON1+game.m_num;//重新加1个水果game.m_snakeNum++;//蛇的长度加1str.Format("%d",game.m_snakeNum);

GetDlgItem(IDC_EDIT4)->SetWindowTextA(str);

}

CDialog::OnTimer(nIDEvent);

}

如下再介绍应用在对话框中来响应键盘消息，我写的是一个键盘“钩子”，代码如下：

HHOOKg_hKeyboard=NULL;

HWNDg_hWnd=NULL;

LRESULTCALLBACKKeyboardProc(

intcode,

//hookcodeWPARAMwParam,//virtual-keycode

LPARAMlParam//keystroke-messageinformation

)

{

if(wParam==game.turnUP)

{

if(game.m_direction.y==0)game.m_direction=UP;

}

elseif(wParam==game.turnDOWN)

{

if(game.m_direction.y==0)game.m_direction=DOWN;

}

elseif(wParam==game.turnLEFT)

{

if(game.m_direction.x==0)game.m_direction=LEFT;

}

elseif(wParam==game.turnRIGHT)

{

if(game.m_direction.x==0)game.m_direction=RIGHT;

}

else

;

return1;

}

然后介绍一下，点击鼠标右键出现菜单：voidCSnakeDlg::OnRButtonDown(UINTnFlags,CPointpoint)

{

if(game.m_run)

KillTimer(1);

CMenuoMenu;

if(oMenu.LoadMenu(IDR_MENU1))

{

CMenu*pPopup=oMenu.GetSubMenu(0);

ASSERT(pPopup!=NULL);

CPointoPoint;

GetCursorPos(&oPoint);

SetForegroundWindow();

pPopup->TrackPopupMenu(TPM_LEFTALIGN,oPoint.x,oPoint.y,this);

}

if(game.m_run)SetTimer(1,game.m_gameSpeed,NULL);

CDialog::OnRButtonDown(nFlags,point);

}然后来介绍一下程序中是怎样来改变按键的，首先说一下，我开始用EDIT控件来让用户输入，但是程序中我用的是键盘“钩子”来处理消息的，所以EDIT控件在程序中是不可以输入信息的，所以我选的是下拉列表，代码如下，解释也在程序中相应给出：intkeyNum[40]={//定义玩家可以设的键，把所有的键信息存在这个数组中VK_UP,VK_DOWN,VK_LEFT,VK_RIGHT,'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',VK_NUMPAD0,VK_NUMPAD1,VK_NUMPAD2,VK_NUMPAD3,VK_NUMPAD4,VK_NUMPAD5,VK_NUMPAD6,VK_NUMPAD7,VK_NUMPAD8,

VK_NUMPAD9};

voidCSnakeDlg::OnKeyset()//键盘设置响应消息函数

{

//TODO:在此添加命令处理程序代码

if(game.m_run)

KillTimer(1);

CKeySetDlgdlg;

if(dlg.DoModal()==IDOK)

{

if(dlg.m_up==dlg.m_down||dlg.m_up==dlg.m_left||dlg.m_up==dlg.m_right||dlg.m_down==dlg.m_left||dlg.m_down==dlg.m_right||dlg.m_left==dlg.m_right)

{

MessageBox("键位不能设置为重复的，设置失败!");

if(game.m_run)SetTimer(1,game.m_gameSpeed,NULL);

return;

}

game.turnUP=keyNum[GetMarkNum(dlg.m_up)];//重新设置键game.turnDOWN=keyNum[GetMarkNum(dlg.m_down)];

game.turnLEFT=keyNum[GetMarkNum(dlg.m_left)];

game.turnRIGHT=keyNum[GetMarkNum(dlg.m_right)];

}

if(game.m_run)SetTimer(1,game.m_gameSpeed,NULL);

}

intCSnakeDlg::GetMarkNum(CStringstr)//返回重新设置键对应数组的“索引”

{

intbackNum=0;

if(str=="上")

backNum=0;

elseif(str=="下")

backNum=1;

elseif(str=="左")

backNum=2;

elseif(str=="右")

backNum=3;

else

{

CStringss;

for(chari='A';i<='Z';++i)

{

ss.Format("%c",i);

if(ss==str.Right(1))

{

backNum=i-'A'+4;

returnbackNum;

}

}

for(inti=0;i<=9;++i)

{

ss.Format("%d",i);

if(ss==str.Right(1))

{

backNum=i+30;

returnbackNum;
