本篇博客梳理贪吃蛇小游戏具体的代码实现
游戏代码文件分布逻辑如下：

Snake.h：标准库头文件的包含，类型的声明，函数的声明
Snake.c：游戏功能的具体实现
test.c：游戏的测试逻辑
下面来进行贪吃蛇的具体代码实现

一、游戏开始（运行前准备）-GameStart

函数原型如下

void GameStart(pSnake ps);

void GameStart(pSnake ps) 
{ 
	//1.设置游戏窗口的大小与窗口名字
	system("mode con cols=100 lines=30"); 
	system("title 贪吃蛇"); 
	
	//2.隐藏屏幕光标
	HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE); //获取标准输出的句柄
	CONSOLE_CURSOR_INFO CursorInfo; //创建光标信息结构体
	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 
	//3.打印欢迎界⾯ 
	WelcomeToGame(); 
	//4.创建地图 
	CreateMap(); 
	//5.初始化蛇身 
	InitSnake(ps); 
	//6.创造⻝物 
	CreateFood(ps); 
}

1．打印欢迎界面：WelcomeToGame函数

逻辑：定位光标->打印->清屏

void WelcomeToGame()
{
	SetPos(40, 14);
	wprintf(L"欢迎来到贪吃蛇小游戏\n");
	SetPos(42, 20);
	system("pause");
	system("cls");
	SetPos(25, 14);
	wprintf(L"用 ↑. ↓ . ← . → 来控制蛇的移动，按F3加速，F4减速\n");
	SetPos(25, 15);
	wprintf(L"加速能够得到更高的分数\n");

	SetPos(42, 20);
	system("pause");
	system("cls");
}

注：SetPos定位的坐标可以自行调整，目的是为了打印的布局好看一些

2．创建地图：CreateMap函数

逻辑：实现27行，58列（包括墙体在内）的地图，在头文件中定义一下墙的符号会更为方便
在头文件中定义

#define WALL L'□'

void CreateMap()
{
	//上边界
	int i = 0;
	for (i = 0; i < 29; i++)
	{
		wprintf(L"%lc", WALL);
	}

	//下边界
	SetPos(0, 26);
	for (i = 0; i < 29; i++)
	{
		wprintf(L"%lc", WALL);
	}

	//左边界
	for (i = 1; i <= 25; i++)
	{
		SetPos(0, i);
		wprintf(L"%lc", WALL);
	}

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

3．初始化蛇身：InitSnake函数

逻辑：将指向蛇的指针传给这个函数，并作如下操作

（1）创建一条五个节点的蛇

（2）打印蛇

（3）设置蛇的属性

void InitSnake(pSnake ps)
{
	int i = 0;
	pSnakeNode cur = NULL;
	//创建蛇身的五个节点
	for (i = 0; i < 5; i++)
	{
		cur = (pSnakeNode)malloc(sizeof(SnakeNode));
		if (cur == NULL)
		{
			perror("InitSnake()::malloc()");
			return;
		}
		cur->next = NULL;
		cur->x = POS_X + 2 * i;//POS_X：在头文件中声明的初始x坐标
		cur->y = POS_Y;//POS_Y：在头文件中声明的初始y坐标

		//头插法插入链表
		if (ps->_pSnake == NULL) //空链表
		{
			ps->_pSnake = cur;
		}
		else //非空
		{
			cur->next = ps->_pSnake;
			ps->_pSnake = cur;
		}
	}

	cur = ps->_pSnake;
	while (cur)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);
		cur = cur->next;
	}

	//设置贪吃蛇的属性
	ps->_dir = RIGHT;//默认向右
	ps->_score = 0;//当前分数是0分
	ps->_food_weight = 10;//每个食物10分
	ps->_sleep_time = 200;//单位是毫秒
	ps->_status = OK;

}

4．创建食物：CreateFood函数

逻辑如下

(1)随机生成x和y，x的范围是[2,54]，y的范围是[1,25]

(2)确定x和y不能和蛇身坐标冲突

(3)创建食物的节点

食物节点直接利用蛇的节点即可，只不过要把其中的next指针置为NULL，这样子就不用创建新的类型了

void CreateFood(pSnake ps)
{
	int x = 0;
	int y = 0;

	//特别注意：生成的x是2的倍数
	//x：2~54
	//y: 1~25
again:
	do
	{
		x = rand() % 53 + 2;
		y = rand() % 25 + 1;
	} while (x % 2 != 0);

	//遍历蛇，看坐标有无冲突
	pSnakeNode cur = ps->_pSnake;
	while (cur)
	{
		if (x == cur->x && y == cur->y)
		{
			goto again;//如果生成的x,y和蛇身坐标冲突，就回去继续生成新的x,y
		}
		cur = cur->next;
	}

	//创建食物的节点
	pSnakeNode pFood = (pSnakeNode)malloc(sizeof(SnakeNode));
	if (pFood == NULL)
	{
		perror("CreateFood()::malloc()");
		return;
	}

	pFood->x = x;
	pFood->y = y;
	pFood->next = NULL;

	SetPos(x, y);//定位食物的位置
	wprintf(L"%lc", FOOD);

	ps->_pFood = pFood;//把食物放到贪吃蛇结构中去维护
}

二、游戏运行-GameRun

函数原型如下

void GameRun(pSnake ps);

虚拟键值注明如下：
• 上：VK_UP
• 下：VK_DOWN
• 左：VK_LEFT
• 右：VK_RIGHT
• 空格：VK_SPACE
• ESC：VK_ESCAPE
• F3：VK_F3
• F4：VK_F4

void GameRun(pSnake ps)
{
	PrintHelpInfo();//打印帮助信息
	do
	{
		//打印总分数和食物的分值
		SetPos(64, 10);
		printf("总分数:%d\n", ps->_score);
		SetPos(64, 11);
		printf("当前食物的分数:%2d\n", ps->_food_weight);
//获取按键情况：KEY_PRESS
		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();//暂停游戏——睡眠即可
		}
		else if (KEY_PRESS(VK_ESCAPE))
		{
			//正常退出游戏
			ps->_status = END_NORMAL;
		}
		else if (KEY_PRESS(VK_F3))
		{
			//加速
			if (ps->_sleep_time > 80)
			{
				ps->_sleep_time -= 30;
				ps->_food_weight += 2;
			}
		}
		else if (KEY_PRESS(VK_F4))
		{
			//减速
			if (ps->_food_weight > 2)
			{
				ps->_sleep_time += 30;
				ps->_food_weight -= 2;
			}
		}

		SnakeMove(ps);//蛇走一步的过程

		Sleep(ps->_sleep_time);

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

1．打印说明信息：PrintHelpInfo函数

void PrintHelpInfo()
{
	SetPos(64, 14);
	wprintf(L"%ls", L"不能穿墙，不能咬到自己");
	SetPos(64, 15);
	wprintf(L"%ls", L"用 ↑. ↓ . ← . → 来控制蛇的移动");
	SetPos(64, 16);
	wprintf(L"%ls", L"按F3加速，F4减速");
	SetPos(64, 17);
	wprintf(L"%ls", L"按ESC退出游戏，按空格暂停游戏");
}

2．根据按键情况移动蛇：SnakeMove函数

void SnakeMove(pSnake ps)
{
	//创建一个结点，表示蛇即将到的下一个节点
	pSnakeNode pNextNode = (pSnakeNode)malloc(sizeof(SnakeNode));
	if (pNextNode == NULL)
	{
		perror("SnakeMove()::malloc()");
		return;
	}
//根据蛇头的坐标与方向，计算下一个节点的坐标
	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;
	}

	//检测下一个坐标处是不是食物
	if (NextIsFood(pNextNode, ps))
	{
		EatFood(pNextNode, ps);
	}
	else
	{
		NoFood(pNextNode, ps);
	}

	//检测蛇是否撞墙
	KilledByWall(ps);
	//检测蛇是否撞到自己
	KilledBySelf(ps);
}

（1）判断下一个节点是不是食物：NextIsFood函数

是就返回1，不是就返回0

int NextIsFood(pSnakeNode pn, pSnake ps)
{
	return (ps->_pFood->x == pn->x && ps->_pFood->y == pn->y);
}

①是：吃掉食物并作相应处理——EatFood函数

void EatFood(pSnakeNode pn, pSnake ps)
{
	//头插法，把食物节点头插到蛇身
	ps->_pFood->next = ps->_pSnake;
	ps->_pSnake = ps->_pFood;

	//释放下一个位置的节点
	free(pn);
	pn = NULL;

	pSnakeNode cur = ps->_pSnake;
	//打印蛇
	while (cur)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);
		cur = cur->next;
	}
	ps->_score += ps->_food_weight;

	//重新创建新的食物
	CreateFood(ps);
}

②不是：尾巴删除一节——NoFood函数

void NoFood(pSnakeNode pn, pSnake ps)
{
	//头插法，把下一个节点插到蛇身
	pn->next = ps->_pSnake;
	ps->_pSnake = pn;

	pSnakeNode cur = ps->_pSnake;
	while (cur->next->next != NULL)
	{
		SetPos(cur->x, cur->y);
		wprintf(L"%lc", BODY);
		cur = cur->next;
	}

	//把最后一个结点打印成空格
	SetPos(cur->next->x, cur->next->y);
	printf("  ");

	//释放最后一个结点
	free(cur->next);

	//把倒数第二个节点的地址置为NULL
	cur->next = NULL;
}

（2）判断是否撞墙：KilledByWall

void KilledByWall(pSnake ps)
{
	if (ps->_pSnake->x == 0 || ps->_pSnake->x == 56 ||
		ps->_pSnake->y == 0 || ps->_pSnake->y == 26)
	{
		ps->_status = KILL_BY_WALL;
	}
}

（3）判断是否撞上自己：KilledBySelf

void KilledBySelf(pSnake ps)
{
	pSnakeNode cur = ps->_pSnake->next;
	while (cur)
	{
		if (cur->x == ps->_pSnake->x && cur->y == ps->_pSnake->y)
		{
			ps->_status = KILL_BY_SELF;
			break;
		}
		cur = cur->next;
	}
}

（4）暂停：Pause函数

void Pause()
{
	while (1)
	{
		Sleep(200);
		if (KEY_PRESS(VK_SPACE))
		{
			break;
		}
	}
}

三、游戏结束（善后工作）-GameEnd函数

void GameEnd(pSnake ps)
{
	SetPos(24, 12);
	switch (ps->_status)
	{
	case END_NORMAL:
		wprintf(L"您主动结束游戏\n");
		break;
	case KILL_BY_WALL:
		wprintf(L"您撞到墙上，游戏结束\n");
		break;
	case KILL_BY_SELF:
		wprintf(L"您撞到了自己，游戏结束\n");
		break;
	}

	//释放蛇身的链表

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