linux实现贪吃蛇游戏

实现贪吃蛇游戏的方法有很多种，下面是一种使用C语言在Linux平台上实现的方法：

1. 首先需要安装ncurses库，该库提供了在终端中进行文本图形化操作的支持。在终端中执行以下命令安装：

sudo apt-get install libncurses5-dev libncursesw5-dev

2. 创建一个空白的.c文件，例如snake.c，然后在该文件中编写代码实现贪吃蛇游戏。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <unistd.h>
#include <ncurses.h>

#define ROWS 20
#define COLS 40
#define SCORE_POS 22

#define SNAKE_INIT_LEN 3

enum direction {UP, DOWN, LEFT, RIGHT};

struct point {
    int x;
    int y;
};

typedef struct point Point;

int score = 0;
int gameover = 0;
enum direction dir = RIGHT;
Point snake[ROWS * COLS];
Point food;

void initialize() {
    initscr();
    cbreak();
    noecho();
    curs_set(0);
    keypad(stdscr, TRUE);
    timeout(100);
}

void draw() {
    clear();
    mvprintw(SCORE_POS, 0, "Score: %d", score);
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            if (i == food.y && j == food.x) {
                mvaddch(i, j, '*');
            } else if (i == snake[0].y && j == snake[0].x) {
                mvaddch(i, j, 'H');
            } else {
                int found = 0;
                for (int k = 1; k < SNAKE_INIT_LEN; k++) {
                    if (i == snake[k].y && j == snake[k].x) {
                        mvaddch(i, j, 'T');
                        found = 1;
                        break;
                    }
                }
                if (!found) {
                    mvaddch(i, j, ' ');
                }
            }
        }
    }
    refresh();
}

void generate_food() {
    srand(time(NULL));
    do {
        food.x = rand() % COLS;
        food.y = rand() % ROWS;
    } while (food.x == snake[0].x && food.y == snake[0].y);
}

void move_snake() {
    Point head = snake[0];
    switch (dir) {
        case UP:
            head.y--;
            break;
        case DOWN:
            head.y++;
            break;
        case LEFT:
            head.x--;
            break;
        case RIGHT:
            head.x++;
            break;
    }
    if (head.x < 0 || head.x >= COLS || head.y < 0 || head.y >= ROWS) {
        gameover = 1;
        return;
    }
    snake[0] = head;
    for (int i = SNAKE_INIT_LEN - 1; i > 0; i--) {
        snake[i] = snake[i - 1];
    }
    if (head.x == food.x && head.y == food.y) {
        score++;
        SNAKE_INIT_LEN++;
        generate_food();
    }
    for (int i = 1; i < SNAKE_INIT_LEN; i++) {
        if (snake[i].x == head.x && snake[i].y == head.y) {
            gameover = 1;
            break;
        }
    }
}

void get_input() {
    int key = getch();
    switch (key) {
        case KEY_UP:
            if (dir != DOWN) {
                dir = UP;
            }
            break;
        case KEY_DOWN:
            if (dir != UP) {
                dir = DOWN;
            }
            break;
        case KEY_LEFT:
            if (dir != RIGHT) {
                dir = LEFT;
            }
            break;
        case KEY_RIGHT:
            if (dir != LEFT) {
                dir = RIGHT;
            }
            break;
        default:
            break;
    }
}

void cleanup() {
    endwin();
}

int main() {
    initialize();
    snake[0].x = COLS / 2;
    snake[0].y = ROWS / 2;
    for (int i = 1; i < SNAKE_INIT_LEN; i++) {
        snake[i].x = snake[i - 1].x - 1;
        snake[i].y = snake[i - 1].y;
    }
    generate_food();
    while (!gameover) {
        draw();
        move_snake();
        get_input();
    }
    cleanup();
    printf("Game over! Your score is %d.\n", score);
    return 0;
}

3. 编译代码并运行。

gcc snake.c -o snake -lncurses
./snake

4. 在终端中就可以玩贪吃蛇游戏了。使用方向键控制蛇的移动，吃掉食物可以增加分数，撞到墙或自己就会游戏结束。
