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
简单的准备工作
效果展示

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:
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
cpp
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
cpp
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
cpp
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。
cpp
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。
cpp
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
cpp
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。
cppvoid 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
cpp
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
cpp
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
cpp
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。
cpp
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);
