第 40 行，在欢迎屏幕中 SCREEN.blit(GAME_SPRITE['background'], (0, 0)) TypeError：参数 1 必须是 pygame.Surface，而不是 builtin_function_or_method 我尝试做很多事情也在网上搜索过，但没有得到答案。有人可以帮我吗？

【问题讨论】：

与所有类似图像相比，您对GAME_SPRITE['background'] 的分配似乎缩短了。
这是一个错字。 pygame.image.load(BACKGROUND).convert 必须是 pygame.image.load(BACKGROUND).convert()

标签： python pygame

【解决方案1】：

问题出在这一行：

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert

通过此分配，您的background 是function。你需要这样称呼它：

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert()

【讨论】：

【解决方案2】：

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert 的 convert 部分是函数还是方法？如果是这样，您在它之后缺少()。

将该行更改为

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert()

看看它是否符合你的预期。

如果这样可以解决您的问题，那么问题在于您已将convert 函数分配给GAME_SPRITE['background']，而不是调用convert() 并分配返回值。
