      '''初始化按钮的属性'''
      self.screen = screen
      self.screen_rect = screen.get_rect()
      # 设置按钮的尺寸和其他属性
      self.width, self.height = 200, 50
      self.button_color = (0, 255, 0)
      self.text_color = (255, 255, 255)
      self.font = pygame.font.Font(r'fonts\freesansbold.ttf', 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
      # 按钮的标签只要创建一次
      self.prep_msg(msg)
