Python贪吃蛇游戏高级代码

Python贪吃蛇游戏的高级代码可以实现更加丰富的游戏功能，例如添加难度级别、计分系统、声音效果等。以下是一个简单的Python贪吃蛇游戏高级代码示例：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 设置游戏窗口尺寸
size = (400, 400)
screen = pygame.display.set_mode(size)

# 设置游戏标题
pygame.display.set_caption("Snake Game")

# 定义贪吃蛇类
class Snake():
    def __init__(self):
        self.x = 200
        self.y = 200
        self.size = 10
        self.body = [[self.x, self.y]]
        self.direction = "RIGHT"

    def move(self):
        if self.direction == "RIGHT":
            self.x += 10
        elif self.direction == "LEFT":
            self.x -= 10
        elif self.direction == "UP":
            self.y -= 10
        elif self.direction == "DOWN":
            self.y += 10
        self.body.insert(0, [self.x, self.y])
        self.body.pop()

    def change_direction(self, direction):
        if direction == "RIGHT" and self.direction != "LEFT":
            self.direction = "RIGHT"

            self.direction = "UP"
        elif direction == "DOWN" and self.direction != "UP":
            self.direction = "DOWN"

# 定义食物类
class Food():
    def __init__(self):
        self.x = random.randint(0, 39) * 10
        self.y = random.randint(0, 39) * 10

# 初始化贪吃蛇和食物对象

# 设置游戏时钟

# 设置初始分数和字体

        food.respawn()
        snake.body.append(snake.body[-1])
        score += 1

    # 绘制游戏界面
    screen.fill(WHITE)
    for pos in snake.body:
        pygame.draw.rect(screen, BLACK, [pos, pos, snake.size, snake.size])

    # 设置游戏帧率
    clock.tick(10)

# 结束游戏并退出Pygame
pygame.quit()
