【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

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。

import pygame.fontclass Button():def __init__(self,ai_settings,screen,msg):"""初始化按钮的属性"""self.screen = screenself.screen_rect = screen.get_rect()#设置按钮的尺寸和其他属性self.width,self.height = 200,50self.button_color = (0,255,0)self.text_color = (255,255,255)self.font = pygame.font.SysFont(None,48)#创建按钮的rect对象，并使其居中self.rect = pygame.Rect(0,0,self.width,self.height)self.rect.center = self.screen_rect.center#按钮的标签只需创建一次self.prep_msg(msg)def prep_msg(self,msg):"""将msg渲染为图像，并使其在按钮上居中"""self.msg_image = self.font.render(msg,True,self.text_color,self.button_color)self.msg_image_rect = self.msg_image.get_rect()self.msg_image_rect.center = self.rect.centerdef draw_button(self):# 绘制一个用颜色填充的按钮，再绘制文本self.screen.fill(self.button_color,self.rect)self.screen.blit(self.msg_image,self.msg_image_rect)

game_stata.py

一个统计游戏分数的类与初始化游戏期间变化量。

class GameStats():"""跟踪游戏的统计信息"""def __init__(self,ai_settings):"""初始化统计信息"""self.ai_settings = ai_settingsself.reset_stats()#游戏刚启动时处于非活动状态self.game_active = False#在任何情况下都不应重置最高分self.high_score = 0def reset_stats(self):"""初始化在游戏运行期间可能变化的统计信息"""self.wxzs_left = self.ai_settings.wxz_limitself.score = 0self.level = 1

【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。
