贪吃蛇

四、核心的实现

游戏测试

c 复制代码
#include <locale.h>
void test()
{
    int ch = 0;
    srand((unsigned int)time(NULL));//时间戳,用来实现随机数
    do
    {
        Snake snake = { 0 };
        GameStart(&snake);
 
        GameRun(&snake);
 
        GameEnd(&snake);
 
        SetPos(20, 15);
        printf("再来⼀局吗?(Y/N):");
        ch = getchar();
        getchar();
    } while (ch == 'Y');
    SetPos(0, 27);
   }
int main()
{
    //修改当前地区为本地模式,为了⽀持中⽂宽字符的打印
    setlocale(LC_ALL, "");
    //测试逻辑
    test();
    return 0;
}

1、GameStart

(1)控制台窗口大小和名字设置

c 复制代码
system("mode con cols=100 lines=30");
system("title 贪吃蛇");

(2)光标隐藏

c 复制代码
	HANDLE houtput = GetStdHandle(STD_OUTPUT_HANDLE);
	CONSOLE_CURSOR_INFO CursorInfo;
	GetConsoleCursorInfo(houtput, &CursorInfo);
	CursorInfo.bVisible = false;
	SetConsoleCursorInfo(houtput, &CursorInfo);

(3)打印欢迎界面

c 复制代码
void WelcomeToGame()
{
    SetPos(40, 15);
    printf("欢迎来到贪吃蛇⼩游戏");
    SetPos(40, 25);// "按任意键继续"的出现的位置
    system("pause");//可以让页面暂停在这个位置,直到用户按下一个键
    system("cls");//清除屏幕
    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);
    // "按任意键继续"的出现的位置,这里可以让文字出现的位置看起来比较美观
    system("pause");
    system("cls");
}


(4)创建地图

组成地图的小格子需要用宽字符打印

58行就打印29次

c 复制代码
#define WALL L'□'  
//在头文件中定义
void CreateMap()
{
	//上
	int i = 0;
	for (i = 0; i < 29; i++)
	{
		wprintf(L"%lc", WALL);
	}

	//下
	SetPos(0, 26);
	for (i = 0; i < 29; i++)
	{
		wprintf(L"%lc", WALL);
	}
	//左
	for (i = 1; i <= 25; i++)
	{
		SetPos(0, i);
		wprintf(L"%lc", WALL);
	}

	//右
	for (i = 1; i <= 25; i++)
	{
		SetPos(56, i);
		wprintf(L"%lc", WALL);
	}
}

(5)初始化蛇

c 复制代码
void InitSnake(pSnake ps)
{
	int i = 0;
	pSnakeNode cur = NULL;
	for (i = 0; i < 5; i++)
	{
		cur = (pSnakeNode)malloc(sizeof(SnakeNode));//创建蛇身节点
		if (cur == NULL)
		{
			perror("malloc fail");
			exit(1);
		}
		cur->next = NULL;
		cur->x = POS_X + 2 * i;//将蛇的节点由蛇尾到蛇头创建好
		cur->y = POS_Y;
		if (ps->_pSnake == NULL)
		{
			ps->_pSnake = cur;//若没有蛇身节点则建立的节点为蛇身节点
		}
		else
		{
			cur->next = ps->_pSnake;
			ps->_pSnake = cur;//若有蛇身节点则新创建的节点成为头节点
		}
	}

	cur = ps->_pSnake;
	while (cur)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);//将蛇的身体依据链表打印出来
		cur = cur->next;
	}
	ps->_dir = RIGHT;//初始蛇的方向
	ps->_food_weight = 10;//每个食物的分数
	ps->_sleep_time = 200;//每两次打印蛇身的间隔,也就是蛇身的速度
	ps->_sorce = 0;//初始总分数
	ps->_status = OK;//蛇的初始状态
}

(6)创建第一个食物

c 复制代码
void CreateFood(pSnake ps)
{
	int x = 0;
	int y = 0;
again:	
	do
	{
		x = rand() % 53 + 2;//我们要的x坐标值介于2~54间,任意数%53得到的值介于0~52,加上2就在2~56范围
		y = rand() % 25 + 1;//我们要的y坐标值介于1~25间,任意数%25得到的值介于0~24,加上1就在1~25范围
		//随机数时间戳,根据时间计算的数据,由于时间是不可修改切没有相同时候的,所以它产生的数字被认为是随机数
	} while (x % 2 != 0);

	pSnakeNode cur = ps->_pSnake;//记录蛇头结点
	while (cur)
	{
		if (x == cur->x && y == cur->y)
		{
			goto again;
		}
		cur = cur->next;
	}//如果食物与蛇身上某一节点重合了,则回到again处重新生成
	pSnakeNode pFood = (pSnakeNode)malloc(sizeof(SnakeNode));//不重合就生成食物
	if (pFood == NULL)
	{
		perror("malloc fail");
		exit(2);
	}
	pFood->x = x;
	pFood->y = y;
	pFood->next = NULL;

	SetPos(x, y);
	wprintf(L"%lc", FOOD);//在对应位置处打印食物
	ps->_pFood = pFood;
}

最终的GameStart

c 复制代码
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;
    //获取控制台光标信息
    GetConsoleCursorInfo(hOutput, &CursorInfo);
    //隐藏控制台光标
    CursorInfo.bVisible = false; 
    //设置控制台光标状态
    SetConsoleCursorInfo(hOutput, &CursorInfo);
    
    //打印欢迎界⾯
    WelcomeToGame();
    //打印地图
    CreateMap();
    //初始化蛇
    InitSnake(ps);
    //创造第⼀个⻝物
    CreateFood(ps);
}

2、GameRun

(1)定义一个宏来检测按键状态

c 复制代码
#define KEY_PRESS(VK) ((GetAsyncKeyState(VK)&0x1) ? 1 : 0)

在上一篇博文中我们介绍了GetAsyncKeyState函数,我们封装一个宏可以判断某个键是否被按下

(2)PrintHelpInfo

c 复制代码
void PrintHelpInfo()
{
	SetPos(64, 14);
	wprintf(L"%ls", L"不能穿墙,不能咬到自己");
	SetPos(64, 16);
	wprintf(L"%ls", L"用 ↑. ↓ . ← . → 来控制蛇的移动");
	SetPos(64, 18);
	wprintf(L"%ls", L"按F3加速,F4减速");
	SetPos(64, 20);
	wprintf(L"%ls", L"按ESC退出游戏,按空格暂停游戏");

	SetPos(64, 24);
	wprintf(L"%ls", L"s_little_monster_倾情制作");
}

(3)SnakeMove

c 复制代码
void SnakeMove(pSnake ps)
{
	pSnakeNode pNextNode = (pSnakeNode)malloc(sizeof(SnakeNode));//开辟预测的下一个节点
	if (pNextNode == NULL)
	{
		perror("malloc fail");
		exit(3);
	}
	switch (ps->_dir)//用switch语句判断此时蛇的走向
	{
	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;//注意左右移动是加减2
		pNextNode->y = ps->_pSnake->y;
		break;
	case RIGHT:
		pNextNode->x = ps->_pSnake->x + 2;
		pNextNode->y = ps->_pSnake->y;
		break;
	}

	if (NextIsFood(pNextNode, ps))
	{
		EatFood(pNextNode,ps);
	}
	else
	{
		NoFood(pNextNode, ps);
	}
	//判断下一个位置是否为食物,是则进入EatFood,不是则进入NoFood
	KillBySelf(ps);
	
	KillByWall(ps);//检查是否撞到自己或墙而死亡
}

(4)NextIsFood

c 复制代码
int NextIsFood(pSnakeNode pn,pSnake ps)
{
	return (ps->_pFood->x == pn->x && ps->_pFood->y == pn->y);
	//如果当前位置是食物则返回非0值,不是返回0
}

(5)EatFood

c 复制代码
void EatFood(pSnakeNode pn, pSnake ps)
{
	ps->_pFood->next = ps->_pSnake;
	ps->_pSnake = ps->_pFood;//吃掉食物,让食物成为蛇的头节点
	free(pn);//因为节点pn与节点_pFood是一个节点,所以free掉其中的一个
	pn = NULL;
	pSnakeNode cur = ps->_pSnake;
	while (cur)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);
		cur = cur->next;
	}//打印蛇身
	ps->_sorce += ps->_food_weight;//加分
	CreateFood(ps);//重新制造食物
}

(6)NoFood

c 复制代码
void NoFood(pSnakeNode pn, pSnake ps)
{
	pn->next = ps->_pSnake;
	ps->_pSnake = pn;//同EatFood,将下一节点成为头结点
	pSnakeNode cur = ps->_pSnake;
	while (cur->next->next != NULL)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);
		cur = cur->next;
	}//将除了尾节点以外的节点打印
	SetPos(cur->next->x, cur->next->y);
	printf("  ");//将尾节点打印为空格
	free(cur->next);//free掉尾节点
	cur->next = NULL;
}

(7)KillBySelf

c 复制代码
void KillBySelf(pSnake ps)
{
	pSnakeNode pur = ps->_pSnake->next;
	while (pur)
	{
		//当此时的蛇头位置与蛇身某一节点重合时
		if (pur->x == ps->_pSnake->x && pur->y == ps->_pSnake->y)
		{
			ps->_status = KILL_BY_SELF;//修改状态为 KILL_BY_SELF
			break;
		}
		pur = pur->next;
	}
}

(8)KillByWall

c 复制代码
void KillByWall(pSnake ps)
{
	//当此时的蛇头位置与墙体重合时
	if (ps->_pSnake->x == 0 || ps->_pSnake->x == 56 || ps->_pSnake->y == 0 || ps->_pSnake->y == 26)
	{
		ps->_status = KILL_BY_WALL;//修改状态为 KILL_BY_WALL
	}
}

最终的GameRun

c 复制代码
void GameRun(pSnake ps)
{
	PrintHelpInfo();//游戏玩法帮助打印
	do
	{
		SetPos(64, 10);
		printf("总分数:%d\n", ps->_sorce);
		SetPos(64, 11);
		printf("当前食物的分数:%2d\n", ps->_food_weight);
		//检测键是否被按下
		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();//暂停,等待再按下空格继续
		}
		else if (KEY_PRESS(VK_ESCAPE))
		{
			ps->_status = END_NORMAL;
		}
		else if (KEY_PRESS(VK_F3))//F3为加速,休眠时间变少也就是蛇的速度变快,每个食物分数增加2
		{
			if(ps->_sleep_time > 80)//速度不能太快
			{
				ps->_sleep_time -= 30;
				ps->_food_weight += 2;
			}
		}
		else if (KEY_PRESS(VK_F4))//F4为减速,休眠时间变多也就是蛇的速度变慢,每个食物分数减少2
		{
			if(ps->_food_weight > 2)//食物分数要在2分以上
			{
				ps->_sleep_time += 30;
				ps->_food_weight -= 2;
			}
		}
		SnakeMove(ps);//蛇每走一步要进行的活动
		Sleep(ps->_sleep_time);//走一步休眠的时间,也就是蛇的速度
	} while (ps->_status == OK);//当游戏状态为OK时循环继续
}

3、GameEnd

当游戏状态不为OK时,告知游戏结束的原因并释放蛇身

c 复制代码
void GameEnd(pSnake ps)
{
	SetPos(24, 12);
	switch (ps->_status)
	{
	case END_NORMAL:
		wprintf(L"主动结束游戏");
		break;
	case KILL_BY_SELF:
		wprintf(L"撞到自己了,游戏结束");
		break;
	case KILL_BY_WALL:
		wprintf(L"撞到墙了,游戏结束");
		break;
	}

	pSnakeNode pur = ps->_pSnake;
	while (pur)
	{
		pSnakeNode del = pur;
		pur = pur->next;
		free(del);
	}
}
