【CODE】

**hotdog.py**

在游戏中导入hotdog图像，并且设置hotdog属性以及创建绘制和更新函数。

import pygame
    from pygame.sprite import Sprite
    
    class Hotdog(Sprite):
        """"表示单个hotdog的类"""
    
        def __init__(self,ai_settings,screen,wxz):

            self.rect.y = self.y

button.py

创建一个开始按钮，并且只有用鼠标点击play按钮之后游戏才能开始。

### 【游戏界面】 ###

至此，游戏全部完成，但是很多功能不够完善，比如自动发射hotdog等等，比如像雷电一样可以自由移动等等......

等待后续更新吧。
