帮我用c语言写一个贪吃蛇游戏代码

好的，我可以回答这个问题。以下是一个简单的贪吃蛇游戏的 C 语言代码： ``` #include <stdio.h> #include <stdlib.h> #include <conio.h> #include <windows.h> #define WIDTH 20 #define HEIGHT 20 #define FOOD '$' #define SNAKE_HEAD '@' #define SNAKE_BODY '*' int score = ; int speed = 100; struct Snake { int x; int y; struct Snake *next; }; struct Snake *head = NULL; struct Snake *tail = NULL; char map[HEIGHT][WIDTH]; void init_map() { int i, j; for (i = ; i < HEIGHT; i++) { for (j = ; j < WIDTH; j++) { if (i == || i == HEIGHT - 1 || j == || j == WIDTH - 1) { map[i][j] = '#'; } else { map[i][j] = ' '; } } } } void draw_map() { int i, j; system("cls"); for (i = ; i < HEIGHT; i++) { for (j = ; j < WIDTH; j++) { printf("%c", map[i][j]); } printf("\n"); } printf("Score: %d\n", score); } void add_snake(int x, int y) { struct Snake *node = (struct Snake *)malloc(sizeof(struct Snake)); node->x = x; node->y = y; node->next = NULL; if (head == NULL) { head = node; tail = node; } else { tail->next = node; tail = node; } } void init_snake() { add_snake(WIDTH / 2, HEIGHT / 2); add_snake(WIDTH / 2 + 1, HEIGHT / 2); add_snake(WIDTH / 2 + 2, HEIGHT / 2); } void draw_snake() { struct Snake *p = head; while (p != NULL) { map[p->y][p->x] = (p == head) ? SNAKE_HEAD : SNAKE_BODY; p = p->next; } } void move_snake(int dx, int dy) { int x = head->x + dx; int y = head->y + dy; if (map[y][x] == '#' || map[y][x] == SNAKE_BODY) { printf("Game Over!\n"); exit(); } if (map[y][x] == FOOD) { add_snake(x, y); score += 10; if (speed > 50) { speed -= 10; } generate_food(); } else { map[tail->y][tail->x] = ' '; tail->x = x; tail->y = y; head = tail; tail = tail->next; } } void generate_food() { int x, y; do { x = rand() % (WIDTH - 2) + 1; y = rand() % (HEIGHT - 2) + 1; } while (map[y][x] != ' '); map[y][x] = FOOD; } void play_game() { int dx = 1, dy = ; while (1) { if (_kbhit()) { char ch = _getch(); if (ch == 'a' && dx != 1) { dx = -1; dy = ; } else if (ch == 'd' && dx != -1) { dx = 1; dy = ; } else if (ch == 'w' && dy != 1) { dx = ; dy = -1; } else if (ch == 's' && dy != -1) { dx = ; dy = 1; } } move_snake(dx, dy); draw_map(); draw_snake(); Sleep(speed); } } int main() { init_map(); init_snake(); generate_food(); draw_map(); draw_snake(); play_game(); return ; } ```
