2.2难度选择时动画：

3.游戏界面历史最高分显示：

4.游戏结束界面：

4.1本局游戏分数、历史最高分数显示：

4.2退出游戏和再玩一次功能实现：

五.总结

本文的贪吃蛇小游戏根据从零开始用 Python 打造经典贪吃蛇游戏：代码+详解_pygame贪吃蛇游戏代码-CSDN博客进行改进优化，在原有的基础功能上增加了通过界面按钮可选择难度、历史最高分显示、结束游戏可选择继续游戏等功能，进一步优化了小游戏的体验感受。

一.运行效果

游戏开始界面：

游戏界面：

游戏结束界面：

二.使用说明

首先我们打开Pycharm，没有安装的小伙伴可以看这个安装教程。新建一个项目，在项目里新建一个main.py文件，再把完整代码粘贴到main.py文件中，注意：

①.在终端输入以下命令安装pygame库：

pip install pygame

②.修改第31行的save_path为“你项目的地址/score.txt”;

再运行main.py即可。

三.完整代码

话不多少，直接上完整代码：

四.代码讲解

1.按钮类：

增加按钮类，用于按钮创建，定义显示按钮函数draw和检查点是否在按钮內函数is_clicked。

class Button:def __init__(self, text, x, y, width, height, font_size, font_color):self.text = textself.rect = pygame.Rect(x, y, width, height)self.font = pygame.font.Font(None, font_size)self.text_surf = self.font.render(self.text, True, font_color)self.text_rect = self.text_surf.get_rect(center=self.rect.center)def draw(self, screenn,bg_color):pygame.draw.rect(screenn, bg_color, self.rect)screen.blit(self.text_surf, self.text_rect)def is_clicked(self, pos):if self.rect.collidepoint(pos):return True
