环境安装：
Python3.6、pycharm2021、游戏模块Pygame。

安装：pip installpygame

?初始化游戏加载素材：

def initGame(): pygame.init()screen = pygame.display.set_mode(cfg.SCREENSIZE)pygame.display.set_caption('中秋月饼小游戏') game_images = {}for key, value in cfg.IMAGE_PATHS.items():if isinstance(value, list):images = []for item in value: images.append(pygame.image.load(item))game_images[key] = imageselse:game_images[key] = pygame.image.load(value)game_sounds = {}for key, value in cfg.AUDIO_PATHS.items():if key == 'bgm': continuegame_sounds[key] = pygame.mixer.Sound(value) return screen, game_images, game_sounds

主函数定义：
