Pygame :参数1必须是> pygame.Surface，而不是pygame.Rect

Question

我正在为我的游戏制作一个帮助屏幕，每当我运行它时，我都会收到这条错误消息：

self.surface.blit(self.helpscreen) TypeError:参数1必须是> pygame.Surface，而不是pygame.Rect

我不知道如何解决它，我仍然在学习游戏，所以我需要一个相当基本的答案，如果可能的话。我的代码如下：

def help(self):

    pygame.init()
    self.FPS = 60
    self.fps_clock = pygame.time.Clock()
    self.surface = pygame.display.set_mode((640, 480))
    helpscreen = DISPLAY_SURF.fill(white)
    self.surface.blit(helpscreen)
    # This class sets the basic attributes for the window.
    # The clock is set to 60 and the name of the window
    # is set to The Hunt which is a working title for my project
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    while True:
        pygame.display.update()
        self.fps_clock.tick(self.FPS)
        self.process_game()

只需填充显示面self.surface.fill(white)或创建背景面并在self.surface上空白：

helpscreen = pygame.Surface(self.surface.get_size())
helpscreen.fill(white)
self.surface.blit(helpscreen, (0, 0))
