贪吃蛇小游戏（C语言）

贪吃蛇游戏的功能结构

• 上面大体是贪吃蛇的整体构架，我们按照这个思想往下写代码
  宏定义

• 定义上下左右四个方向

#define U 1
#define D 2
#define L 3
#define R 4

定义全局变量

• 包括结构体，以及其他各个函数需要用到的变量

typedef struct snake  //蛇身节点
{ int x;  //节点的x坐标int y;  //节点的y坐标struct snake *next;  //蛇身的下一个节点
}snake;int score = 0, add = 10;  //总得分和每一次吃食物得分
int HighScore = 0;  //最高分
int status, sleeptime = 200;  //蛇前进状态，每次运行的时间间隔
snake *head, *food;  //蛇头指针，食物指针
snake *q;  //遍历蛇时候用的指针
int endgamestatus = 0;  //游戏结束的情况，1：撞到墙，2：咬到自己，3：主动退出游戏
HANDLE hOut;  //控制台句柄

函数声明

• 游戏中所有用到的函数

void gotoxy(int x, int y); //设置光标位置
int color(int c);//更改文字颜色
void printsnake();//字符画——蛇
void welcometogame();//开始画面
void createMap();//绘制地图
void scoreandtips();//游戏界面右侧的得分和小提示
void initsnake();//初始化蛇身，画蛇身
void createfood();//创建并随机出现食物
int biteself();//判断是否咬到自己
void cantcrosswall();//设置蛇撞墙的情况
void speedup();//加速
void speeddown();//减速
void snakemove();//控制蛇前进方向
void keyboardControl();//控制键盘按键
void Lostdraw();//游戏结束界面
void endgame();//游戏结束
void choose();//游戏失败之后的选择
void File_out();//在文件中读取最高分
void File_in();//存储最高分文件
void explation();//游戏说明

以上代码在头文件中定义

下面的我就介绍各个不同的函数

• 定义color函数

int color(int c)  //改变颜色
{SetConsoleTextAttribute(GetStdHandle(STD_ERROR_HANDLE), c);return 0;
}

• 定义gotoxy()函数

void gotoxy(int x, int y)  //设置光标位置
{COORD c;c.X = x;c.Y = y;SetConsoleCursorPosition(GetStdHandle(STD_ERROR_HANDLE), c);
}

• 绘制字符蛇的形状（大家可以根据个人的喜好，自行搭配颜色）

void printsnake()
{gotoxy(35, 1);color(6);printf("/^\\/^\\");gotoxy(34, 2);printf("|_| O|");gotoxy(33, 2);color(2); printf("_");gotoxy(25, 3);color(12);printf("\\/");gotoxy(31, 3);color(2);printf("/");gotoxy(37, 3);color(6);printf("\\_/");gotoxy(41, 3);color(10);printf("\\");gotoxy(26, 4);color(12);printf("\\____");gotoxy(32, 4);printf("__________/");gotoxy(31, 4);color(2);printf("|");gotoxy(43, 4);color(10);printf("\\");gotoxy(32, 5);color(2);printf("\\_____");gotoxy(44, 5);color(10);printf("\\");gotoxy(39, 6);printf("|    |             \\");gotoxy(38, 7);printf("/   /                \\");gotoxy(37, 8);printf("/  /                \\ \\");gotoxy(35, 9);printf("/  /                    \\ \\");gotoxy(34, 10);printf("/  /                        \\ \\");gotoxy(33, 11);printf("/  /          __---__     \\  \\");gotoxy(32, 12);printf("/  /        _-~     ~-_    \\  \\");gotoxy(31, 13);printf("             _-~    _--_  ~-_   -/  \ ");gotoxy(32, 14);printf("\\       ~-____-~   _-~    ~-_    ~-_-~    \\  \\");gotoxy(33, 15);printf("~-_         _-~    ~-_     _-~");gotoxy(35, 16);printf("~--______-~         ~-___-~");
}

• 啊哈，我画的蛇比较难看，美术不好，呜呜呜，大家可以自己搭配，做一条好看的蛇
• 绘制菜单选项

void welcometogame()
{int n;int i, j = 1;gotoxy(43, 18);color(11);printf("贪吃蛇游戏");color(14);for (i = 20; i < 26; i++){for (j = 27; j <= 74; j++){gotoxy(j, i);if (i == 20 || i == 26){printf("-");}else if (j == 27 || j == 74){printf("|");}}}color(12);gotoxy(35, 22);printf("1.开始游戏");gotoxy(55, 22);printf("2.游戏说明");gotoxy(35, 24);printf("3.退出游戏");gotoxy(29, 27);color(3);printf("请选择【1 2 3】：[ ]\b\b");color(14);scanf("%d", &n);switch (n){case 1:system("cls");createMap();initsnake();createfood();keyboardControl();break;case 2:explation();break;case 3:exit(0);break;default:color(12);gotoxy(40, 28);printf("请输入1--3之间的数");_getch();system("cls");printsnake();welcometogame();}
}

• 创建游戏地图

void createMap()
{int i, j;for (i = 0; i < 58; i += 2){gotoxy(i, 0);color(5);printf("□");gotoxy(i, 26);printf("□");}for (i = 1; i < 26; i++){gotoxy(0, i);printf("□");gotoxy(56, i);printf("□");}for (i = 2; i < 56; i+=2){for (j = 1; j < 26; j++){gotoxy(i, j);color(3);printf("■\n\n");}}
}

• 绘制右侧得分和小提示

void scoreandtips()
{File_out();gotoxy(64,4);color(11);printf("☆最高记录：%d", HighScore);gotoxy(64, 8);color(14);printf("得分：%d ", score);color(13);gotoxy(73, 11);printf("小 提 示");gotoxy(60, 13);color(6);printf("---------------------");gotoxy(60, 25);printf("---------------------");color(3);gotoxy(64, 14);printf("每个食物得分：%d分", add);gotoxy(64, 16);printf("不能穿墙，不能咬到自己");gotoxy(64, 18);printf("用↑↓←→分别控制蛇的移动");gotoxy(64, 20);printf("F1 为加速，F2 为减速");gotoxy(64, 22);printf("space:暂停游戏");gotoxy(64, 24);printf("ESC:退出游戏");
}

• 读取游戏最高分
• 我将游戏最高分放在文件中，取出来也是从文件中取出来

void File_out()
{FILE *fp;fp = fopen("E:\\vs 项目\贪吃蛇\Debug\save.txt","a+");fscanf(fp, "%d", &HighScore);fclose(fp);
}

• 绘制蛇身

void initsnake()
{snake *tail;int i;tail = (snake*)malloc(sizeof(snake));tail->x = 24;tail->y = 5;tail->next = NULL;for (int i = 1; i < 4; i++){head = (snake*)malloc(sizeof(snake));head->next = tail;head->x = 24 + 2 * i;head->y = 5;tail = head;}while (tail != NULL){gotoxy(tail->x, tail->y);color(14);printf("★");tail = tail->next;}
}

• 创建并随机出现食物

void createfood()
{snake* food_1;srand((unsigned)time(NULL));food_1 = (snake*)malloc(sizeof(snake));while ((food_1->x % 2) != 0){food_1->x = rand() % 52 + 2;}food_1->y = rand() % 24 + 1;q = head;while (q->next == NULL){if (q->x == food_1->x&&q->y == food_1->y){free(food_1);createfood();}q = q->next;}gotoxy(food_1->x, food_1->y);food = food_1;color(12);printf("●");
}

• 判断蛇是否咬到自己

int biteself()
{snake* self;self = head->next;while (self != NULL){if (self->x == head->x&&self->y == head->y){return 1;}self = self->next;}return 0;
}

• 判断蛇是否撞到墙

void cantcrosswall()
{if (head->x == 0 || head->x == 56 || head->y == 0 || head->y == 26){endgamestatus = 1;endgame();}
}

• 设置蛇加速前进

void speedup()
{if (sleeptime >= 50){sleeptime = sleeptime - 10;add = add + 2;if (sleeptime == 320){add = 2;}}
}

• 设置蛇减速前进

void speeddown()
{if (sleeptime < 350){sleeptime = sleeptime + 30;add = add - 2;if (sleeptime == 350){add = 1;}}
}

• 设置蛇在不按键的时候蛇的前进方向

void snakemove()
{snake *nexthead;cantcrosswall();nexthead = (snake*)malloc(sizeof(snake));if (status == U){nexthead->x = head->x;nexthead->y = head->y - 1;nexthead->next = head;head = nexthead;q = head;if (nexthead->x == food->x&&nexthead->y == food->y){while (q != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}score = score + add;speedup();createfood();}else{while (q->next->next != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}gotoxy(q->next->x, q->next->y);color(3);printf("■");free(q->next);q->next = NULL;}}if (status == D){nexthead->x = head->x;nexthead->y = head->y + 1;nexthead->next = head;head = nexthead;q = head;if (nexthead->x == food->x&&nexthead->y == food->y){while (q != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}score = score + add;speedup();createfood();}else{while (q->next->next != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}gotoxy(q->next->x, q->next->y);color(3);printf("■");free(q->next);q->next = NULL;}}if (status == L){nexthead->x = head->x - 2;nexthead->y = head->y;nexthead->next = head;head = nexthead;q = head;if (nexthead->x == food->x&&nexthead->y == food->y){while (q != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}score = score + add;speedup();createfood();}else{while (q->next->next != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}gotoxy(q->next->x, q->next->y);color(3);printf("■");free(q->next);q->next = NULL;}}if (status == R){nexthead->x = head->x + 2;nexthead->y = head->y;nexthead->next = head;head = nexthead;q = head;if (nexthead->x == food->x&&nexthead->y == food->y){while (q != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}score = score + add;speedup();createfood();}else{while (q->next->next != NULL){gotoxy(q->x, q->y);color(14);printf("★");q = q->next;}gotoxy(q->next->x, q->next->y);color(3);printf("■");free(q->next);q->next = NULL;}}if (biteself() == 1){endgamestatus = 2;endgame();}
}

• 通过键盘方向键控制蛇前进的方向

void keyboardControl()
{status = R;while (1){scoreandtips();if (GetAsyncKeyState(VK_UP) && status != D){status = U;}else if (GetAsyncKeyState(VK_DOWN) && status != U){status = D;}else if (GetAsyncKeyState(VK_LEFT) && status != R){status = L;}else if (GetAsyncKeyState(VK_RIGHT) && status != L){status = R;}if (GetAsyncKeyState(VK_SPACE)){while (1){Sleep(300);if (GetAsyncKeyState(VK_SPACE)){break;}}}else if (GetAsyncKeyState(VK_ESCAPE)){endgamestatus = 3;break;}else if (GetAsyncKeyState(VK_F1)){speedup();}else if (GetAsyncKeyState(VK_F2)){if (sleeptime < 350){sleeptime = sleeptime + 30;add = add - 2;if (sleeptime == 350){add = 1;}}}Sleep(sleeptime);snakemove();}
}

• 游戏失败界面设计

void Lostdraw()
{system("cls");int i, j;gotoxy(45, 2);color(6);printf("\\\\\\|///");gotoxy(43, 3);printf("\\\\");gotoxy(47, 3);color(15);printf(".-.-");gotoxy(54, 3);color(6);printf("//");gotoxy(44, 4);color(14);printf("(");gotoxy(47, 4);color(15);printf(".@.@");gotoxy(54, 4);color(14);printf(")");gotoxy(17, 5);color(11);printf("+-----------------");gotoxy(35, 5);color(14);printf("oOOo");gotoxy(39, 5);color(11);printf("-------");gotoxy(48, 5);color(14);printf("(__)");gotoxy(51, 5);color(11);printf("--------");gotoxy(61, 5);color(14);printf("oOOo");gotoxy(65, 5);color(11);printf("--------");for (i = 6; i <= 19; i++){gotoxy(17, i);printf("|");gotoxy(82, i);printf("|");}gotoxy(17, 20);printf("+-----------------");gotoxy(52, 20);color(14);printf("☆☆☆  ");gotoxy(60, 20);color(11);printf("-----------------+");
}

• 打印游戏结束界面的信息

void endgame()
{system("cls");if (endgamestatus == 1){Lostdraw();gotoxy(35, 9);color(12);printf("对不起，您撞到墙了。游戏结束！");}else if (endgamestatus == 2){Lostdraw();gotoxy(35, 9);color(12);printf("对不起，您咬到自己了。游戏结束！");}else if (endgamestatus == 3){Lostdraw();gotoxy(40, 9);color(12);printf("您已经结束了游戏！");}gotoxy(43, 12);color(13);printf("您的得分是 %d", score);if (score >= HighScore){color(10);gotoxy(33, 16);printf("创造新记录了！最高分被你刷新了，真棒！！！");File_in();}else{color(10);gotoxy(33, 16);printf("继续努力吧~~~~你离最高分还差: %d", HighScore - score);}choose();
}

• 存储游戏的最高分

void File_in()
{FILE *fp;fp = fopen("E:\\vs 项目\贪吃蛇\Debug\save.txt", "w+");fprintf(fp, "%d", score);fclose(fp);
}

• 设计分支选项

void choose()
{int n;gotoxy(25, 23);color(12);printf("我要重新玩一局------ 1");gotoxy(52, 23);printf("不玩了，退出吧------ 2");gotoxy(46, 25);color(11);printf("选择：");scanf("%d", &n);switch (n){case 1:system("cls");score = 0;sleeptime = 200;add = 10;printsnake();welcometogame();break;case 2:exit(0);break;default:gotoxy(35, 27);color(12);printf("XXX您的输入有误，请重新输入XXX");system("pause>nul");endgame();choose();break;}
}

• 游戏说明模块的实现

void explation()
{int i, j = 1;system("cls");color(13);gotoxy(44, 3);printf("游戏说明");color(2);for (i = 6; i <= 22; i++){for (j = 20; j <= 75; j++){gotoxy(j, i);if (i == 6 || i == 22)printf("=");else if (j == 20 || j == 75)printf("||");}}color(3);gotoxy(30, 8);printf("tip1:不能穿墙，不能咬到自己");color(10);gotoxy(30, 11);printf("tip2:用↑.↓.←.→分别控制蛇的移动");color(14);gotoxy(30, 14);printf("tip3:F1为加速，F2为减速");color(11);gotoxy(30, 17);printf("tip4：按空格键暂停游戏，再按空格键继续");color(4);gotoxy(30, 20);printf("tip5:ESP：退出游戏, space : 暂停游戏");_getch();system("cls");printsnake();welcometogame();
}

好了，所有函数已经完全实现

• 看看主函数

int main()
{system("mode con cols=100 lines=30");printsnake();welcometogame();File_out();keyboardControl();endgame();system("pause");
}
