c语言怎么编贪吃蛇

编写贪吃蛇游戏需要涉及到以下几个步骤：

1、初始化游戏界面

2、绘制蛇和食物

3、控制蛇的移动

4、检测蛇是否吃到食物

5、检测蛇是否撞到自己或者墙壁

6、更新游戏状态

下面是一个简单的C语言实现贪吃蛇游戏的代码：

#include <conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <windows.h>
#define WIDTH 50
#define HEIGHT 25
int snake_x[WIDTH * HEIGHT], snake_y[WIDTH * HEIGHT];
int food_x, food_y;
int snake_length;
int direction;
void init() {
    srand(time(NULL));
    snake_length = 3;
    for (int i = 0; i < snake_length; i++) {
        snake_x[i] = WIDTH / 2 i;
        snake_y[i] = HEIGHT / 2;
    }
    direction = 0;
    food_x = rand() % WIDTH;
    food_y = rand() % HEIGHT;
}
void draw() {
    system("cls");
    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 == food_x && y == food_y) {
                printf("*");
            } else {
                int is_snake = 0;
                for (int i = 0; i < snake_length; i++) {
                    if (x == snake_x[i] && y == snake_y[i]) {
                        is_snake = 1;
                        break;
                    }
                }
                if (is_snake) {
                    printf("o");
                } else {
                    printf(" ");
                }
            }
        }
        printf("
");
    }
}
void update() {
    int prev_x = snake_x[0], prev_y = snake_y[0];
    int prev2_x, prev2_y;
    if (direction == 0) {
        snake_y[0];
    } else if (direction == 1) {
        snake_x[0]++;
    } else if (direction == 2) {
        snake_y[0]++;
    } else if (direction == 3) {
        snake_x[0];
    }
    for (int i = 1; i < snake_length; i++) {
        prev2_x = snake_x[i];
        prev2_y = snake_y[i];
        snake_x[i] = prev_x;
        snake_y[i] = prev_y;
        prev_x = prev2_x;
        prev_y = prev2_y;
    }
    if (snake_x[0] == food_x && snake_y[0] == food_y) {
        snake_length++;
        food_x = rand() % WIDTH;
        food_y = rand() % HEIGHT;
    }
}
int is_game_over() {
    if (snake_x[0] == 0 || snake_x[0] == WIDTH 1 || snake_y[0] == 0 || snake_y[0] == HEIGHT 1) {
        return 1;
    }
    for (int i = 1; i < snake_length; i++) {
        if (snake_x[0] == snake_x[i] && snake_y[0] == snake_y[i]) {
            return 1;
        }
    }
    return 0;
}
void input() {
    if (_kbhit()) {
        char ch = _getch();
        if (ch == 'w' && direction != 2) {
            direction = 0;
        } else if (ch == 'd' && direction != 3) {
            direction = 1;
        } else if (ch == 's' && direction != 0) {
            direction = 2;
        } else if (ch == 'a' && direction != 1) {
            direction = 3;
        }
    }
}
int main() {
    init();
    while (!is_game_over()) {
        draw();
        input();
        update();
        Sleep(100);
    }
    printf("Game Over!
");
    return 0;
}

这个代码实现了一个简单的贪吃蛇游戏，你可以在Windows系统上的C编译器中运行这个代码，游戏中，你可以使用W、A、S、D键来控制蛇的移动方向。
