属性错误： 'builtin_function_or_method'对象没有属性'blit'

Question

我正在制作一个flappy bird游戏a.我使用pygame和neat遵循教程系列教程链接，我收到了以下错误消息：

Traceback (most recent call last):
File "c:UserspcDesktopPYTHONFlappy bird AIflappy_bird.py", line 108, in <module>
main()
File "c:UserspcDesktopPYTHONFlappy bird AIflappy_bird.py", line 104, in main
draw_window(win, bird)
File "c:UserspcDesktopPYTHONFlappy bird AIflappy_bird.py", line 87, in draw_window
Bird.draw(bin)
File "c:UserspcDesktopPYTHONFlappy bird AIflappy_bird.py", line 79, in draw
win.blit(rotated_image, new_rect.topleft)
AttributeError: 'builtin_function_or_method' object has no attribute 'blit'

这是代码：

这只是一个拼写错误，您在draw_window函数中编写了Bird.draw(bin)而不是Bird.draw(win)。

这个功能应该是这样的：

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