用python写贪吃蛇小游戏代码

很高兴回答你的问题。以下是一个简单的 Python 贪吃蛇小游戏代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

# 定义颜色
BLACK = (, , )
WHITE = (255, 255, 255)
GREEN = (, 255, )
RED = (255, , )

# 创建游戏窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('贪吃蛇')

# 定义蛇的初始位置和大小
snake_x = 100
snake_y = 100
snake_width = 20
snake_height = 20

# 定义蛇的移动速度
snake_speed = 20

# 定义食物的初始位置和大小
food_x = random.randint(, WINDOW_WIDTH - snake_width)
food_y = random.randint(, WINDOW_HEIGHT - snake_height)
food_width = 20
food_height = 20

# 定义蛇的初始长度和方向
snake_length = 1
snake_direction = 'right'

# 定义字体
font = pygame.font.SysFont(None, 30)

# 定义游戏结束函数
def game_over():
    message = font.render('游戏结束！', True, RED)
    message_rect = message.get_rect()
    message_rect.center = (WINDOW_WIDTH / 2, WINDOW_HEIGHT / 2)
    window.blit(message, message_rect)
    pygame.display.update()
    pygame.time.delay(200)
    pygame.quit()
    quit()

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                snake_direction = 'left'
            elif event.key == pygame.K_RIGHT:
                snake_direction = 'right'
            elif event.key == pygame.K_UP:
                snake_direction = 'up'
            elif event.key == pygame.K_DOWN:
                snake_direction = 'down'

    # 移动蛇
    if snake_direction == 'left':
        snake_x -= snake_speed
    elif snake_direction == 'right':
        snake_x += snake_speed
    elif snake_direction == 'up':
        snake_y -= snake_speed
    elif snake_direction == 'down':
        snake_y += snake_speed

    # 判断是否吃到食物
    if snake_x < food_x + food_width and snake_x + snake_width > food_x and snake_y < food_y + food_height and snake_y + snake_height > food_y:
        food_x = random.randint(, WINDOW_WIDTH - snake_width)
        food_y = random.randint(, WINDOW_HEIGHT - snake_height)
        snake_length += 1

    # 绘制游戏界面
    window.fill(WHITE)
    pygame.draw.rect(window, GREEN, [food_x, food_y, food_width, food_height])
    snake_head = []
    snake_head.append(snake_x)
    snake_head.append(snake_y)
    snake_list = []
    snake_list.append(snake_head)
    if len(snake_list) > snake_length:
        del snake_list[]
    for segment in snake_list:
        pygame.draw.rect(window, BLACK, [segment[], segment[1], snake_width, snake_height])
    pygame.display.update()

    # 判断游戏是否结束
    if snake_x <  or snake_x > WINDOW_WIDTH - snake_width or snake_y <  or snake_y > WINDOW_HEIGHT - snake_height:
        game_over()
    for segment in snake_list[:-1]:
        if segment == snake_head:
            game_over()

希望这个代码对你有帮助！
