用c语言编写游戏:贪吃蛇: 要求: 1、设定游戏显示界面及边界;用键盘按键移动贪吃蛇; 2、初始状态下，用‘*’表示蛇头，用‘。’表示食物，食物在游戏界面区域内随机出现，必须是蛇头吞食食物后才改变食物位置，每次出现1个 3、根据规则，只能蛇头触碰食物，蛇头触碰食物后，身体变化，用’。’表示，其余郎分触碰食物，游戏结束; 4、蛇头触碰身体，游戏结束。 5、显示吞食食物个数，表示游戏分值. 代码给我

好的，以下是用 C 语言编写的贪吃蛇游戏代码，实现了上述要求：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <conio.h>
#include <windows.h>

// 游戏界面大小
#define WIDTH 30
#define HEIGHT 20

// 蛇的最大长度
#define MAX_LENGTH (WIDTH * HEIGHT)

// 定义方向枚举类型
enum Direction {
    UP,
    DOWN,
    LEFT,
    RIGHT
};

// 定义节点结构体
struct Node {
    int x;
    int y;
};

// 定义蛇结构体
struct Snake {
    struct Node *body;
    int length;
    enum Direction direction;
};

// 定义食物结构体
struct Food {
    int x;
    int y;
};

// 定义游戏状态结构体
struct GameState {
    int score;
    int food_eaten;
    struct Snake snake;
    struct Food food;
};

// 定义函数，用于初始化游戏状态
void init_game(struct GameState *state) {
    // 初始化随机种子
    srand((unsigned int)time(NULL));

    // 初始化蛇的位置和方向
    state->snake.body = (struct Node *)malloc(sizeof(struct Node) * MAX_LENGTH);
    state->snake.body[0].x = WIDTH / 2;
    state->snake.body[0].y = HEIGHT / 2;
    state->snake.length = 1;
    state->snake.direction = RIGHT;

    // 初始化食物的位置
    state->food.x = rand() % WIDTH;
    state->food.y = rand() % HEIGHT;

    // 初始化分数和食物数量
    state->score = 0;
    state->food_eaten = 0;
}

// 定义函数，用于绘制游戏界面
void draw_game(struct GameState *state) {
    system("cls");  // 清屏

    // 绘制游戏界面
    for (int y = 0; y < HEIGHT; y++) {
        for (int x = 0; x < WIDTH; x++) {
            if (x == 0 || x == WIDTH - 1 || y == 0 || y == HEIGHT - 1) {
                printf("#");
            } else if (x == state->snake.body[0].x && y == state->snake.body[0].y) {
                printf("*");
            } else if (x == state->food.x && y == state->food.y) {
                printf(".");
            } else {
                int flag = 0;
                for (int i = 1; i < state->snake.length; i++) {
                    if (x == state->snake.body[i].x && y == state->snake.body[i].y) {
                        printf(".");
                        flag = 1;
                        break;
                    }
                }
                if (!flag) {
                    printf(" ");
                }
            }
        }
        printf("\n");
    }

    // 显示分数和食物数量
    printf("Score: %d, Food: %d\n", state->score, state->food_eaten);
}

// 定义函数，用于更新游戏状态
void update_game(struct GameState *state) {
    // 处理按键输入
    if (_kbhit()) {
        switch (_getch()) {
            case 'w':
            case 'W':
                if (state->snake.direction != DOWN) {
                    state->snake.direction = UP;
                }
                break;
            case 's':
            case 'S':
                if (state->snake.direction != UP) {
                    state->snake.direction = DOWN;
                }
                break;
            case 'a':
            case 'A':
                if (state->snake.direction != RIGHT) {
                    state->snake.direction = LEFT;
                }
                break;
            case 'd':
            case 'D':
                if (state->snake.direction != LEFT) {
                    state->snake.direction = RIGHT;
                }
                break;
            default:
                break;
        }
    }

    // 移动蛇的位置
    for (int i = state->snake.length - 1; i > 0; i--) {
        state->snake.body[i].x = state->snake.body[i - 1].x;
        state->snake.body[i].y = state->snake.body[i - 1].y;
    }
    switch (state->snake.direction) {
        case UP:
            state->snake.body[0].y--;
            break;
        case DOWN:
            state->snake.body[0].y++;
            break;
        case LEFT:
            state->snake.body[0].x--;
            break;
        case RIGHT:
            state->snake.body[0].x++;
            break;
        default:
            break;
    }

    // 判断是否吃到食物
    if (state->snake.body[0].x == state->food.x && state->snake.body[0].y == state->food.y) {
        state->food.x = rand() % WIDTH;
        state->food.y = rand() % HEIGHT;
        state->snake.length++;
        state->score += 10;
        state->food_eaten++;
    }

    // 判断是否游戏结束
    if (state->snake.body[0].x == 0 || state->snake.body[0].x == WIDTH - 1 ||
        state->snake.body[0].y == 0 || state->snake.body[0].y == HEIGHT - 1) {
        printf("Game Over!\n");
        exit(0);
    }
    for (int i = 1; i < state->snake.length; i++) {
        if (state->snake.body[0].x == state->snake.body[i].x &&
            state->snake.body[0].y == state->snake.body[i].y) {
            printf("Game Over!\n");
            exit(0);
        }
    }
}

// 定义主函数
int main() {
    struct GameState state;
    init_game(&state);
    while (1) {
        draw_game(&state);
        update_game(&state);
        Sleep(100);  // 控制帧率
    }
    return 0;
}

这个代码实现了一个简单的贪吃蛇游戏，游戏界面大小为 30x20，使用 W、A、S、D 键控制蛇的移动方向，吃到食物后蛇的长度加 1，当蛇碰到边界或者自己时游戏结束。
