如何用C++编译贪食蛇

1、首先打开C++编译器。慎级

2、然后点击File点击New再点击source File创建。

3、再输入代码：

#include<graphics.h>

 

#include<stdlib.h>

 

#include<dos.h>

 

#define LEFT 0x4b00

 

#define RIGHT 0x4d00

 

#define DOWN 0x5000

 

#define UP 0x4800

 

#define ESC 0x011b

4、int i,key;

 

int score=0;

 

int gamespeed=32000;

 

struct Food /*食物的结构体*/

 

{

 

int x; /*食物的横坐标*/

 

int y; /*食物的纵坐标*/

 

int yes; /*食物是否出现的变量*/

 

}food;

 

struct Snack /*蛇的结构体*/

 

{

 

int x[N];

 

int y[N];

 

int node; /*蛇的节数*/

 

int direction; /*蛇的方向*/

 

int life; /*蛇的生命，0活着，1死亡*/

 

}snake;

 

void Init(void); /*图形驱动*/

 

void Close(void); /*关闭游戏函数*/

 

void DrawK(void); /*画图函数*/

 

void GameOver(void);/*输出失败函数*/

 

void GamePlay(); /*游戏控制函数 主要程序*/

 

void PrScore(void); /*分数输出函数*/

 

5、DELAY(char ch)/*调节游戏速度*/

 

{

 

if(ch=='3')

 

{

 

delay(gamespeed); /*delay是延迟函数*/

 

delay(gamespeed);

 

}

 

else if(ch=='2')

 

{

 

delay(gamespeed);

 

}

 

}

 

Menu()/*游戏开始菜单*/

 

{

 

char ch;

 

printf("Please choose the gamespeed:\n");

 

printf("1-Fast 2-Normal 3-Slow\n");

 

printf("\nPlease Press The numbers..\n");

 

do

 

{ch=getch();}

 

while(ch!='1'&&ch!='2'&&ch!='3');

 

clrscr();

 

return(ch);

 

}

 

6、/*主函数*/

 

void main(void)

 

{

 

int ch;

 

ch=Menu();

 

Init();

 

DrawK();

 

GamePlay(ch);

 

Close();

 

}

 

void Init(void)

 

{

 

int gd=DETECT,gm;

 

initgraph(&gd,&gm,"c:\\tc");

 

cleardevice();

 

}

 

void DrawK(void)

 

{

 

setcolor(11);

 

setlinestyle(SOLID_LINE,0,THICK_WIDTH);

 

for(i=50;i<=600;i+=10)

 

{

 

rectangle(i,40,i+10,49); /*画出上边框*/

 

rectangle(i,451,i+10,460); /*画出下边框*/

 

}

 

for(i=40;i<=450;i+=10)

 

{

 

rectangle(50,i,59,i+10); /*画出左边框*/

 

rectangle(601,i,610,i+10); /*画出右边框*/

 

}

 

}

 

7、void GamePlay(char ch)

 

{

 

randomize(); /*随机数发生器*/

 

food.yes=1; /*1代表要出现食物，0表示以存在食物*/

 

snake.life=0;

 

snake.direction=1;

 

snake.x[0]=100;snake.y[0]=100;

 

snake.x[1]=110;snake.y[1]=100;

 

snake.node=2;

 

PrScore();

 

while(1) /*可以重复游戏*/

 

{

 

while(!kbhit()) /*在没有按键的情况下蛇自己移动*/

 

{

 

if(food.yes==1) /*需要食物*/

 

{

 

food.x=rand()%400+60;

 

food.y=rand()%350+60; /*使用丽冷rand函数随机产生食物坐标*/

 

while(food.x%10!=0)

 

food.x++;

 

while(food.y%10!=0)

 

food.y++; /*判断食物是否虚三吩出现在整格里*/

 

food.yes=0; /*现在有食物了*/

 

}

 

if(food.yes==0) /*有食物了就要显示出来*/

 

{

 

setcolor(GREEN);

 

rectangle(food.x,food.y,food.x+10,food.y-10);

 

}

 

for(i=snake.node-1;i>0;i--) /*贪吃蛇的移动算法*/

 

{

 

snake.x[i]=snake.x[i-1];

 

snake.y[i]=snake.y[i-1]; /*贪吃蛇的身体移动算法*/

 

}

 

 

if(key==RIGHT&&snake.direction!=2)

 

snake.direction=1;

 

else

 

if(key==LEFT&&snake.direction!=1)

 

snake.direction=2;

 

else

 

if(key==DOWN&&snake.direction!=3)

 

snake.direction=4;

 

}

 

}

 

void GameOver(void)

 

{

 

cleardevice();

 

setcolor(RED);

 

settextstyle(0,0,4);

 

outtextxy(200,200,"GAME OVER");

 

getch();

 

}

 

void PrScore(void)

 

{

 

char str[10];

 

setfillstyle(SOLID_FILL,YELLOW);

 

bar(50,15,220,35);

 

setcolor(6);

 

settextstyle(0,0,2);

 

sprintf(str,"scord:%d",score);

 

outtextxy(55,20,str);

 

}

 

void Close(void)

 

{

 

getch();

 

closegraph();

 

}

8、switch(snake.direction) /*贪吃蛇的头部移动算法，以此来控制移动*/

 

{

 

case 1:snake.x[0]+=10;break;

 

case 2:snake.x[0]-=10;break;

 

case 3:snake.y[0]-=10;break;

 

case 4:snake.y[0]+=10;break;

 

}

 

for(i=3;i<snake.node;i++) /*判断是否头部与身体相撞*/

 

{

 

if(snake.x[i]==snake.x[0]&&snake.y[i]==snake.y[0])

 

{

 

GameOver();

 

snake.life=1;

 

break;

 

}

 

}

 

/*下面是判断是否撞到墙壁*/

 

if(snake.x[0]<55||7a686964616fe58685e5aeb931333262356639snake.x[0]>595||snake.y[0]<55||snake.y[0]>455)

 

{

 

GameOver();

 

snake.life=1;

 

}

 

if(snake.life==1) /*如果死亡就退出循环*/

 

break;

 

if(snake.x[0]==food.x&&snake.y[0]==food.y) /*判断蛇是否吃到食物*/

 

{

 

setcolor(0);

 

rectangle(food.x,food.y,food.x+10,food.y-10); /*吃的食物后用黑色将食物擦去*/

 

snake.x[snake.node]=-20;snake.y[snake.node]=-20; /*现把增加的一节放到看不到的地方去*/

 

snake.node++;

 

food.yes=1;

 

score+=10;

 

PrScore();

 

}

 

setcolor(4); /*每次移动后将后面的身体擦去*/

 

for(i=0;i<snake.node;i++)

 

rectangle(snake.x[i],snake.y[i],snake.x[i]+10,snake.y[i]-10);

 

delay(gamespeed);

 

DELAY(ch);

 

setcolor(0);

 

rectangle(snake.x[snake.node-1],snake.y[snake.node-1],snake.x[snake.node-1]+10,snake.y[snake.node-1]-10);

 

9、}

 

if(snake.life==1)

 

break;

 

key=bioskey(0); /*接受按键*/

 

if(key==ESC)

 

break;

 

else

}

 

10、void GameOver(void)

 

{

 

cleardevice();

 

setcolor(RED);

 

settextstyle(0,0,4);
