使用linux编写一个贪吃蛇游戏

好的，下面是一个简单的贪吃蛇游戏示例代码，使用了Python和Pygame库，可以在Linux系统上运行：

import pygame
import random

# 初始化
pygame.init()

# 设置窗口大小
width = 500
height = 500
screen = pygame.display.set_mode((width, height))

# 设置颜色
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)

# 设置字体
font = pygame.font.SysFont(None, 25)

# 设置蛇和食物大小
block_size = 10

# 定义函数：绘制蛇
def snake(snake_List):
    for block in snake_List:
        pygame.draw.rect(screen, white, [block[0], block[1], block_size, block_size])

# 定义函数：显示消息
def message(msg, color):
    screen_text = font.render(msg, True, color)
    screen.blit(screen_text, [width / 6, height / 3])

# 游戏循环
def gameLoop():
    game_over = False
    game_close = False

    # 初始化蛇的位置和速度
    x1 = width / 2
    y1 = height / 2
    x1_change = 0
    y1_change = 0
    snake_List = []
    Length_of_snake = 1

    # 初始化食物的位置
    foodx = round(random.randrange(0, width - block_size) / 10.0) * 10.0
    foody = round(random.randrange(0, height - block_size) / 10.0) * 10.0

    # 游戏主循环
    while not game_over:

        # 游戏结束
        while game_close == True:
            screen.fill(black)
            message("You Lost! Press Q-Quit or C-Play Again", red)
            pygame.display.update()

            # 判断用户动作
            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    if event.key == pygame.K_c:
                        gameLoop()

        # 监听用户动作
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x1_change = -block_size
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = block_size
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -block_size
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = block_size
                    x1_change = 0

        # 判断是否撞墙
        if x1 >= width or x1 < 0 or y1 >= height or y1 < 0:
            game_close = True

        # 修改蛇的位置
        x1 += x1_change
        y1 += y1_change

        # 绘制食物
        screen.fill(black)
        pygame.draw.rect(screen, red, [foodx, foody, block_size, block_size])

        # 维护蛇的长度
        snake_Head = []
        snake_Head.append(x1)
        snake_Head.append(y1)
        snake_List.append(snake_Head)
        if len(snake_List) > Length_of_snake:
            del snake_List[0]

        # 判断是否吃到食物
        for block in snake_List[:-1]:
            if block == snake_Head:
                game_close = True

        # 绘制蛇
        snake(snake_List)

        # 更新屏幕
        pygame.display.update()

        # 判断是否吃到食物
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, width - block_size) / 10.0) * 10.0
            foody = round(random.randrange(0, height - block_size) / 10.0) * 10.0
            Length_of_snake += 1

        # 控制游戏速度
        clock = pygame.time.Clock()
        clock.tick(20)

    # 退出游戏
    pygame.quit()
    quit()

# 运行游戏
gameLoop()

你可以将上述代码保存到一个名为 snake.py 的文件中，使用以下命令在Linux终端中运行：

python snake.py

就可以开始游戏了。
