AttributeError：“builtin_function_or_method”对象没有属性“blit”

Question

我正在制作一个弹出的鸟游戏A.I，使用吡咯，并遵循教程系列教程链接，我得到了以下错误信息：

Traceback (most recent call last):
  File "c:\Users\pc\Desktop\PYTHON\Flappy bird AI\flappy_bird.py", line 108, in <module>
    main()

    win.blit(rotated_image, new_rect.topleft)
AttributeError: 'builtin_function_or_method' object has no attribute 'blit'

这只是一个错误，您已经在您的Bird.draw(bin)函数中编写了Bird.draw(win)而不是Bird.draw(win)。

这一职能应如下：

def draw_window(win, Bird):
    win.blit(BG_IMG, BG_IMG.get_rect())
    Bird.draw(win)
    pygame.display.update()
