欢迎来到我的博客

我是大一的新生，这是我的第一篇博客，我也是在最近学完了C语言基础，想在这里分享我制作的第一个小游戏——贪吃蛇。在制作贪吃蛇的过程中，我相当于复习了一遍C语言基础，又学习了一些关于C/C++的内容。希望大家能指正我的代码，我将会虚心接受大家的建议。

游戏效果

可自定义边框大小、目标、速度。

思路

在最初制作贪吃蛇的时候我将其分为了

• 界面部分

int main()                                                             //界面部分{
      printf("输入'o'开始游戏,其他键结束游戏\n");   while (_getch() == 'o')   {
      	eat = 0, gameover_eat = 0;   	system("cls");   	printf("游戏以wsad操作,按'p'键可结束游戏\n请输入边界大小(长,宽)、速度、目标\n");   	system("pause");   	system("cls");   	printf("长(建议50左右):");   	scanf_s("%d", &lo);   	printf("宽(建议30左右):");   	scanf_s("%d", &wi);   	printf("请输入速度(应为整数2左右):");   	scanf_s("%d", &speed);   	printf("请输入目标(自然数):");   	scanf_s("%d", &goal);   	system("cls");   	printf("按任意键开始游戏");   	switch (control())   	{
      	case -1:system("cls");   		printf("游戏结束-失败qwq\n目标为:%d\n最终成绩为:%d\n", goal, gameover_eat);   		break;   	default:system("cls");   		printf("游戏结束-胜利ovo\n目标为:%d\n最终成绩为:%d\n", goal, eat);   		break;   	}   	printf("输入'o'重新开始游戏,其他键结束游戏\n");   }}

• 命令指令行光标移动部分

void move(int x, int y)                                                 //命令指令行光标移动部分{
      COORD  point = {
    (SHORT)x ,  (SHORT)y };                             //光标要设置的位置x,y   HANDLE  HOutput = GetStdHandle(STD_OUTPUT_HANDLE);                   //使用GetStdHandle(STD_OUTPUT_HANDLE)来获取标准输出的句柄   SetConsoleCursorPosition(HOutput, point);                            //设置光标位置}

• wsad的控制及蛇的生成部分

int control()                                                            //wsad的控制及蛇的生成部分{
      Coordinate* c = (struct Coordinate*)calloc(goal + 3, 2 * sizeof(int));//动态生成结构体数组，为蛇的身躯   (*c).x = lo / 2 + rand() % 3 + 1;   (*c).y = wi / 2 + rand() % 3 + 1;   (*(c + 1)).x = (*(c + 2)).x = 0;   (*(c + 1)).y = (*(c + 2)).y = 0;   char temp = 'w', temp_ch = _getch();   char* ch = &temp_ch;   int eat_1 = 0;   while (1)                                                            //前后左右操作   {
      	if (eat == -1 || eat_1 == -1)   	{
      		return -1;   	}   	if (eat == goal)   	{
      		return 0;   	}   	switch (*ch)   	{
      	case 'w': temp = 'w';   		edging_title();                                              //边界输出和计分板输出   		check((*c).x, (*c).y);                                       //吃的数量赋值和食物生成及检测和边界检测   		eat_1 = snack_move(0, -1, ch, c);   		break;   	case 's': temp = 's';   		edging_title();   		check((*c).x, (*c).y);   		eat_1 = snack_move(0, 1, ch, c);   		break;   	case 'a':  temp = 'a';   		edging_title();   		check((*c).x, (*c).y);   		eat_1 = snack_move(-1, 0, ch, c);   		break;   	case 'd': temp = 'd';   		edging_title();   		check((*c).x, (*c).y);   		eat_1 = snack_move(1, 0, ch, c);   		break;   	case 'p':gameover_eat = eat;   		return -1;   	default:   		*ch = temp;   		break;   	}   }   free(c);}

• 边框输出及计分板输出部分

void edging_title()                                                      //边界输出和计分板输出{
      int l, w;   for (w = 0; w < wi; w++)   {
      	if (w == 0 || w == wi - 1)   	{
      		for (l = 0; l < lo; l++)   		{
      			printf("*");   		}   		printf("\n");   	}   	else   	{
      		printf("*");   		for (l = 0; l < lo - 2; l++)   		{
      			printf(" ");   		}   		printf("*\n");   	}   }   move(lo + 1, 0);   printf("goal:%d", goal);   move(lo + 1, 1);   printf("score:%d", eat);}

• 食物生成和检测及边界检测部分

void check(int x, int y)                                                //食物生成及检测和边界检测{
      static int x_food, y_food;                                           //防止被释放   if (x >= lo - 1 || x <= 0 || y >= wi - 1 || y <= 0)                  //边缘检测   {
      	gameover_eat = eat;   	eat = -1;   }   if (eat == 0)   {
      	x_food = lo / 2;   	y_food = wi / 2;   	if (x == x_food && y == y_food)   	{
      		srand((unsigned)time(NULL));                                 //设种子   		x_food = rand() % (lo - 3) + 2;   		y_food = rand() % (wi - 3) + 2;   		eat++;   	}   }   else  if (x == x_food && y == y_food)   {
      	srand((unsigned)time(NULL));                                     //设种子   	x_food = rand() % (lo - 3) + 2;   	y_food = rand() % (wi - 3) + 2;   	eat++;   }   move(x_food, y_food);   printf("x");}

• 蛇的移动部分

int snack_move(int temp_x, int temp_y, char* ch, struct Coordinate* c)   //蛇移动{
      for (int z = eat + 2; z > 0; z--)                                    //检测蛇有没有撞自己   {
      	if ((*c).x == (*(c + z)).x && (*c).y == (*(c + z)).y)   	{
      		gameover_eat = eat;   		return -1;   	}   }   for (int i = eat + 2; i > 0; i--)   {
      	(*(c + i)).x = (*(c + i - 1)).x;   	(*(c + i)).y = (*(c + i - 1)).y;   }   (*c).x += temp_x;   (*c).y += temp_y;   for (int j = eat + 2; j >= 0; j--)   {
      	move((*(c + j)).x, (*(c + j)).y);   	printf("o");   }   move(0, 0);   if (_kbhit())   {
      	*ch = _getch();   }   Sleep(speed * 50);   system("cls");   return 0;}

心得

C语言一本书是完全不够用的，在制作的过程中，我查询了许多资料比如：C语言光标移动到指定位置、rand()的使用、非阻塞的输入函数kbhit()等等。
