Python 贪吃蛇游戏代码示例 - 简单易懂

好的！下面是一个基本的贪吃蛇游戏的Python代码示例：

import pygame
import time
import random

pygame.init()

# 游戏窗口尺寸
window_width = 800
window_height = 600

# 蛇身方块尺寸
block_size = 20

# 游戏速度，值越小速度越快
game_speed = 15

# 颜色定义
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 游戏窗口
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption('贪吃蛇')

clock = pygame.time.Clock()

font_style = pygame.font.SysFont(None, 50)

    for x in snake_list:
        pygame.draw.rect(window, black, [x[0], x[1], block_size, block_size])

def message(msg, color):
    mesg = font_style.render(msg, True, color)
    window.blit(mesg, [window_width/6, window_height/3])

def gameLoop():

    x1 = window_width / 2
    y1 = window_height / 2

    foodx = round(random.randrange(0, window_width - block_size) / 20.0) * 20.0

                        gameLoop()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:

            game_close = True
        x1 += x1_change
        y1 += y1_change
        window.fill(white)
        pygame.draw.rect(window, red, [foodx, foody, block_size, block_size])

            snake_length += 1

        clock.tick(game_speed)

    pygame.quit()


gameLoop()

这是一个简单的贪吃蛇游戏代码，你可以将其复制到一个Python脚本中，并使用Python解释器运行它。游戏窗口将会打开，并且你可以使用方向键来控制蛇移动，目标是吃到食物并尽可能长大。如果蛇碰到边界或自己的身体，则游戏结束。按Q键可以退出游戏，按C键可以重新开始游戏。希望你喜欢这个小游戏！如有需要，可以根据个人喜好进行自定义和扩展。
