前言

贪吃蛇游戏是一个耳熟能详的小游戏,本次我们讲解他的简单的实现,需要掌握基本的API知识(http://t.csdnimg.cn/uHH6y),简单的C语言知识和基本的数据结构链表

蛇的节点

在游戏运⾏的过程中,蛇每次吃⼀个⻝物,蛇的⾝体就会变⻓⼀节,如果我们使⽤链表存储蛇的信 息,那么蛇的每⼀节其实就是链表的每个节点。每个节点只要记录好蛇⾝节点在地图上的坐标就⾏, 所以蛇节点结构如下:

<code> typedef struct SnakeNode

{

int x;

int y;

struct SnakeNode* next;

}SnakeNode, * pSnakeNode;

但是这样不好维护这一条蛇,要管理整条贪吃蛇,我们再封装⼀个Snake的结构来维护整条贪吃蛇

typedef struct Snake

{

pSnakeNode _pSnake;维护整条蛇的指针

pSnakeNode _pFood;维护⻝物的指针

enum DIRECTION _Dir;头的⽅向默认是向右

enum GAME_STATUS _Status;游戏状态

int _Socre;当前获得分数

int _Add;默认每个⻝物10分

int _SleepTime;每⾛⼀步休眠时间

}Snake, * pSnake;

开始前 void GameStart(pSnake ps)

游戏开始,先打印蛇的身体和地图,以及一些帮助的提示语句,先完成一些准备工作

void GameStart(pSnake ps)

{

设置控制台窗⼝的⼤⼩,30⾏,100列

//mode 为DOS命令

system("mode con cols=100 lines=30");

//设置cmd窗⼝名称

system("title 贪吃蛇");

//获取标准输出的句柄(⽤来标识不同设备的数值)

HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE); //影藏光标操作

CONSOLE_CURSOR_INFO CursorInfo; //打印欢迎界⾯

WelcomeToGame(); //打印地图

CreateMap(); //初始化蛇

GetConsoleCursorInfo(hOutput, &CursorInfo);//获取控制台光标信息

CursorInfo.bVisible = false; //隐藏控制台光标

SetConsoleCursorInfo(hOutput, &CursorInfo);//设置控制台光标状态

InitSnake(ps);

//创造第⼀个⻝物

CreateFood(ps);

}

void WelcomeToGame()

在游戏正式开始之前,做⼀些功能提醒,来让玩家了解游戏方法与规则,其中SetPos是一个已经封装后的函数,可以把这个字体打在这个坐标

<code> void WelcomeToGame()

{

SetPos(40, 15);

printf("欢迎来到贪吃蛇⼩游戏");

SetPos(40, 25);//让按任意键继续的出现的位置好看点

system("pause");

system("cls");

SetPos(25, 12);

printf("⽤ ↑ . ↓ . ← . → 分别控制蛇的移动, F3为加速,F4为减速\n");

SetPos(25, 13);

printf("加速将能得到更⾼的分数。\n");

SetPos(40, 25);//让按任意键继续的出现的位置好看点

system("pause");

system("cls");

}

void CreateMap()

创建地图就是将强打印出来,因为是宽字符打印,所有使⽤wprintf函数,打印格式串前使⽤L 打印地图的关键是要算好坐标,才能在想要的位置打印墙体。

void CreateMap()

{

int i = 0;

//上(0,0)-(56, 0)

SetPos(0, 0);

for (i = 0; i < 58; i += 2)

{

wprintf(L"%c", WALL);

} //下(0,26)-(56, 26)

SetPos(0, 26); for (i = 0; i < 58; i += 2)

{ wprintf(L"%c", WALL);

} //左//x是0,y从1开始增⻓

for (i = 1; i < 26; i++)

{

SetPos(0, i);

wprintf(L"%c", WALL);} //是56y从1开始增⻓

for (i = 1; i < 26; i++)

{

SetPos(56, i);

wprintf(L"%c", WALL);

}

}

  void InitSnake(pSnake ps)

蛇最开始⻓度为5节,每节对应链表的⼀个节点,蛇⾝的每⼀个节点都有⾃⼰的坐标。 创建5个节点,然后将每个节点存放在链表中进⾏管理。创建完蛇⾝后,将蛇的每⼀节打印在屏幕上。 再设置当前游戏的状态,蛇移动的速度,默认的⽅向,初始成绩,蛇的状态,每个⻝物的分数。

void InitSnake(pSnake ps)

{

pSnakeNode cur = NULL;

int i = 0;

//创建蛇⾝节点,并初始化坐标

//头插法

for (i = 0; i < 5; i++)

{

//创建蛇⾝的节点

cur = (pSnakeNode)malloc(sizeof(SnakeNode));

if (cur == NULL)

{

perror("InitSnake()::malloc()");

return;

}

//设置坐标

cur->;next = NULL;

cur->x = POS_X + i * 2;

cur->y = POS_Y;

//头插法

if (ps->_pSnake == NULL)

{

ps->_pSnake = cur;

}

else

{

cur->next = ps->_pSnake;

ps->_pSnake = cur;

}

}

//打印蛇的⾝体

cur = ps->_pSnake;

while (cur)

{

SetPos(cur->x, cur->y);

wprintf(L"%c", BODY);

cur = cur->next;

}

//

初始化贪吃蛇数据

ps->_SleepTime = 200;

ps->_Socre = 0;

ps->_Status = OK;

ps->_Dir = RIGHT;

ps->_Add = 10;

}

 void CreateFood(pSnake ps)

先随机⽣成⻝物的坐标 ◦

x坐标必须是2的倍数 ◦⻝物的坐标不能和蛇⾝每个节点的坐标重复 创建⻝物节点,打印⻝物

void CreateFood(pSnake ps)

{

int x = 0;

int y = 0;

again:

//产⽣的x坐标应该是2倍数,这样才可能和蛇头坐标对⻬。

do

{

x = rand() % 53 + 2;

y = rand() % 25 + 1;

} while (x % 2 != 0);

pSnakeNode cur = ps->_pSnake;//获取指向蛇头的指针

//⻝物不能和蛇⾝冲突

while (cur)

{

if (cur->x == x && cur->y == y)

{

goto again;

}

cur = cur->next;

}

pSnakeNode pFood = (pSnakeNode)malloc(sizeof(SnakeNode)); //创建⻝物

if (pFood == NULL)

{

perror("CreateFood::malloc()");

return;

}

else

{

pFood->x = x;

pFood->y = y;

SetPos(pFood->x, pFood->y);

wprintf(L"%c", FOOD);

ps->_pFood = pFood;

}

}

游戏进行 void GameRun(pSnake ps)

游戏运⾏期间,右侧打印帮助信息,提⽰玩家 根据游戏状态检查游戏是否继续,如果是状态是OK,游戏继续,否则游戏结束。 如果游戏继续,就是检测按键情况,确定蛇下⼀步的⽅向,或者是否加速减速,是否暂停或者退出游 戏。 确定了蛇的⽅向和速度,蛇就可以移动了。

void GameRun(pSnake ps)

{

//打印右侧帮助信息

PrintHelpInfo();

do

{

SetPos(64, 10); printf("得分:%d ", ps->_Socre);

printf("每个⻝物得分:%d分", ps->_Add);

if (KEY_PRESS(VK_UP) && ps->_Dir != DOWN)

{

ps->_Dir = UP;

}

else if (KEY_PRESS(VK_DOWN) && ps->_Dir != UP)

{

ps->_Dir = DOWN;

}

else if (KEY_PRESS(VK_LEFT) && ps->_Dir != RIGHT)

{

ps->_Dir = LEFT;

}

else if (KEY_PRESS(VK_RIGHT) && ps->_Dir != LEFT)

{

ps->_Dir = RIGHT;

}

else if (KEY_PRESS(VK_SPACE))

{

pause();

}

else if (KEY_PRESS(VK_ESCAPE))

{

ps->_Status = END_NOMAL;

break;

}

else if (KEY_PRESS(VK_F3))

{

if (ps->_SleepTime >= 50)

{

ps->_SleepTime -= 30;

ps->_Add += 2;

}

}

else if (KEY_PRESS(VK_F4))

{

if (ps->_SleepTime < 350)

{

ps->_SleepTime += 30;

ps->_Add -= 2;

if (ps->_SleepTime == 350)

{

ps->_Add = 1;

}

}

}

//蛇每次⼀定之间要休眠的时间,时间短,蛇移动速度就快

Sleep(ps->_SleepTime);

SnakeMove(ps);

} while (ps->_Status == OK);

}

  int NextIsFood(pSnakeNode psn, pSnake ps)

是一个判断下一个位置是食物的函数,会在下面SnakeMove起到作用,是食物的话将吃掉,不是的话将继续按按键运动

int NextIsFood(pSnakeNode psn, pSnake ps)

{

return (psn->x == ps->_pFood->x) && (psn->y == ps->_pFood->y);

}

 void NoFood(pSnakeNode psn, pSnake ps)

将下⼀个节点头插⼊蛇的⾝体,并将之前蛇⾝最后⼀个节点打印为空格,放弃掉蛇⾝的最后⼀个节点,在时间是毫米的瞬间完成,造成移动的效果

void NoFood(pSnakeNode psn, pSnake ps)

{

//头插法

psn->next = ps->_pSnake;

ps->_pSnake = psn;

pSnakeNode cur = ps->_pSnake;

//打印蛇

while (cur->next->next)

{

SetPos(cur->x, cur->y);

wprintf(L"%c", BODY);

}

//最后⼀个位置打印空格,然后释放节点

SetPos(cur->next->x, cur->next->y);

printf(" ");

free(cur->next);

cur->next = NULL;

}

void SnakeMove(pSnake ps)

蛇⾝移动先创建下⼀个节点,根据移动⽅向和蛇头的坐标,蛇移动到下⼀个位置的坐标。 确定了下⼀个位置后,看下⼀个位置是否是⻝物(NextIsFood),是⻝物就做吃⻝物处理 (EatFood),如果不是⻝物则做前进⼀步的处理(NoFood)。 蛇⾝移动后,判断此次移动是否会造成撞墙(KillByWall)或者撞上⾃⼰蛇⾝(KillBySelf),从⽽影 响游戏的状态

void SnakeMove(pSnake ps)

{

//创建下⼀个节点

pSnakeNode pNextNode = (pSnakeNode)malloc(sizeof(SnakeNode));

if (pNextNode == NULL)

{

perror("SnakeMove()::malloc()");

return;

} //确定下⼀个节点的坐标,下⼀个节点的坐标根据,蛇头的坐标和⽅向确定

switch (ps->_Dir)

{

case UP:

{

pNextNode->x = ps->_pSnake->x;

pNextNode->y = ps->_pSnake->y - 1;

}

break;

case DOWN:

{

pNextNode->x = ps->_pSnake->x;

pNextNode->y = ps->_pSnake->y + 1;

}

break;

case LEFT:

{

pNextNode->x = ps->_pSnake->x - 2;

pNextNode->y = ps->_pSnake->y;

}

break;

case RIGHT:

{

pNextNode->x = ps->_pSnake->x + 2;

pNextNode->y = ps->_pSnake->y;

}

break;

}

//如果下⼀个位置就是⻝物

if (NextIsFood(pNextNode, ps))

{

EatFood(pNextNode, ps);

}

else//如果没有⻝物

{

NoFood(pNextNode, ps);

}

KillByWall(ps);

KillBySelf(ps);

}

游戏结束 void GameEnd(pSnake ps)

游戏结束 游戏状态不再是OK(游戏继续)的时候,要告知游戏技术的原因,并且释放蛇⾝节点。

void GameEnd(pSnake ps)

{

pSnakeNode cur = ps->_pSnake;

SetPos(24, 12);

switch (ps->_Status)

{

case END_NOMAL:

printf("您主动退出游戏\n");

break;

case KILL_BY_SELF: printf("您撞上⾃⼰了 ,游戏结束!\n");

break;

case KILL_BY_WALL:

printf("您撞墙了,游戏结束!\n"); } //释放蛇⾝的节点

while (cur)

{

pSnakeNode del = cur;

cur = cur->next;

free(del);

}
