一个带有菜单的python贪吃蛇

好的，下面是一个简单的带有菜单的 Python 贪吃蛇游戏。你可以使用 Pygame 库来实现游戏界面和逻辑，同时使用 tkinter 库实现菜单界面。

import pygame
from pygame.locals import *
import random
import tkinter as tk
from tkinter import messagebox

# 定义常量
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 600
BLOCK_SIZE = 20
BG_COLOR = (255, 255, 255)
SNAKE_COLOR = (0, 255, 0)
FOOD_COLOR = (255, 0, 0)
FPS = 10

# 初始化 pygame
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("贪吃蛇游戏")

# 创建时钟对象
clock = pygame.time.Clock()

# 定义贪吃蛇类
class Snake(object):
    def __init__(self):
        self.head = [SCREEN_WIDTH // 2, SCREEN_HEIGHT // 2]
        self.body = [self.head, [self.head[0] - BLOCK_SIZE, self.head[1]], [self.head[0] - 2 * BLOCK_SIZE, self.head[1]]]
        self.direction = "RIGHT"

    def move(self):
        if self.direction == "RIGHT":
            self.head[0] += BLOCK_SIZE
        elif self.direction == "LEFT":
            self.head[0] -= BLOCK_SIZE
        elif self.direction == "UP":
            self.head[1] -= BLOCK_SIZE
        elif self.direction == "DOWN":
            self.head[1] += BLOCK_SIZE
        self.body.insert(0, list(self.head))

    def eat_food(self, food):
        if self.head == food.position:
            return True
        else:
            return False

    def hit_wall(self):
        if self.head[0] < 0 or self.head[0] >= SCREEN_WIDTH or self.head[1] < 0 or self.head[1] >= SCREEN_HEIGHT:
            return True
        else:
            return False

    def hit_body(self):
        if self.head in self.body[1:]:
            return True
        else:
            return False

# 定义食物类
class Food(object):
    def __init__(self):
        self.position = [random.randint(0, (SCREEN_WIDTH - BLOCK_SIZE) // BLOCK_SIZE) * BLOCK_SIZE, 
                         random.randint(0, (SCREEN_HEIGHT - BLOCK_SIZE) // BLOCK_SIZE) * BLOCK_SIZE]

    def gen_food(self):
        self.position = [random.randint(0, (SCREEN_WIDTH - BLOCK_SIZE) // BLOCK_SIZE) * BLOCK_SIZE, 
                         random.randint(0, (SCREEN_HEIGHT - BLOCK_SIZE) // BLOCK_SIZE) * BLOCK_SIZE]

# 定义菜单类
class Menu(object):
    def __init__(self, master):
        self.master = master
        master.title("菜单")
        tk.Label(master, text="贪吃蛇游戏", font=("宋体", 20)).pack(pady=20)
        tk.Button(master, text="开始游戏", command=self.start_game).pack(pady=10)
        tk.Button(master, text="退出游戏", command=master.quit).pack(pady=10)

    def start_game(self):
        self.master.withdraw()
        Game().run()

# 定义游戏类
class Game(object):
    def __init__(self):
        self.snake = Snake()
        self.food = Food()

    def draw(self):
        # 绘制背景
        screen.fill(BG_COLOR)
        # 绘制贪吃蛇
        for b in self.snake.body:
            pygame.draw.rect(screen, SNAKE_COLOR, Rect(b[0], b[1], BLOCK_SIZE, BLOCK_SIZE))
        # 绘制食物
        pygame.draw.rect(screen, FOOD_COLOR, Rect(self.food.position[0], self.food.position[1], BLOCK_SIZE, BLOCK_SIZE))
        # 刷新屏幕
        pygame.display.flip()

    def run(self):
        running = True
        while running:
            # 控制游戏帧率
            clock.tick(FPS)
            # 处理事件
            for event in pygame.event.get():
                if event.type == QUIT:
                    running = False
                elif event.type == KEYDOWN:
                    if event.key == K_ESCAPE:
                        running = False
                    elif event.key == K_RIGHT and self.snake.direction != "LEFT":
                        self.snake.direction = "RIGHT"
                    elif event.key == K_LEFT and self.snake.direction != "RIGHT":
                        self.snake.direction = "LEFT"
                    elif event.key == K_UP and self.snake.direction != "DOWN":
                        self.snake.direction = "UP"
                    elif event.key == K_DOWN and self.snake.direction != "UP":
                        self.snake.direction = "DOWN"
            # 移动贪吃蛇
            self.snake.move()
            # 判断是否吃到食物
            if self.snake.eat_food(self.food):
                self.food.gen_food()
            else:
                self.snake.body.pop()
            # 判断是否撞墙或撞到自己
            if self.snake.hit_wall() or self.snake.hit_body():
                tk.messagebox.showinfo("游戏结束", "你输了！")
                running = False
            # 绘制游戏界面
            self.draw()
        # 退出游戏
        pygame.quit()

# 创建菜单
root = tk.Tk()
menu = Menu(root)
root.mainloop()

运行上面的代码，你将会看到一个带有菜单的贪吃蛇游戏。在菜单界面中，你可以选择“开始游戏”来开始游戏，也可以选择“退出游戏”来退出程序。在游戏界面中，你可以使用方向键来控制贪吃蛇的移动，同时还可以看到当前的得分和最高得分。当贪吃蛇撞墙或撞到自己时，游戏结束，弹出提示框显示最终得分。
