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

问题描述

我正在按照教程系列Tutorial link，使用pygame和整洁的方法制作一款飞扬的小鸟游戏A.I，并且收到以下错误消息：

Traceback (most recent call last):
  File "c:\Users\pc\Desktop\PYTHON\Flappy bird AI\flappy_bird.py",line 108,in <module>
    main()
  File "c:\Users\pc\Desktop\PYTHON\Flappy bird AI\flappy_bird.py",line 104,in main
    draw_window(win,bird)
  File "c:\Users\pc\Desktop\PYTHON\Flappy bird AI\flappy_bird.py",line 87,in draw_window
    Bird.draw(bin)
  File "c:\Users\pc\Desktop\PYTHON\Flappy bird AI\flappy_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：

import pygame

WIN_WIDTH = 500
WIN_HEIGHT = 800

BIRD_IMGS = [pygame.transform.scale2x(pygame.image.load(os.path.join(r"C:\Users\pc\Desktop\PYTHON\Flappy bird AI\imgs","bird1.png"))),pygame.transform.scale2x(pygame.image.load(os.path.join(r"C:\Users\pc\Desktop\PYTHON\Flappy bird AI\imgs","bird2.png"))),"bird3.png")))]

        if d >= 16:
            d = 16

        if d < 0:
            d -= 2
        
        self.y = self.y + d
        
        if d < 0 or self.y < self.height + 50:

                self.tilt = self.MAX_ROTATION

        else: 
            if self.tilt >-90:
                self.tilt -= self.ROT_VEL

    # This draw function deals with flapping of wings animation.
    def draw(self,win):
        self.img_count += 1

        if self.img_count < self.ANIMATION_TIME:
            self.img = self.IMGS[0]

        elif self.img_count < self.ANIMATION_TIME*3:
            self.img_count = self.IMGS[2]
        elif self.img_count < self.ANIMATION_TIME*4:
            self.img_count = self.IMGS[1]
        elif self.img_count == self.ANIMATION_TIME*4 + 1:
            self.img_count = self.IMGS[0]
            self.img_count = 0

        if self.tilt <= -80:
            self = self.IMGS[1]
            self.img_count = self.ANIMATION_TIME*2     

        rotated_image = pygame.transform.rotate(self.img,self.tilt)

def get_mask(self):
        return pygame.mask.from_surface(self.img)

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

def main():
    bird = Bird(200,200)
    win = pygame.display.set_mode((WIN_WIDTH,WIN_HEIGHT))
    clock = pygame.time.Clock()
    run = True
    while run:
        clock.tick
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False
                pygame.quit()
                quit()

        Bird.move
        draw_window(win,bird)

    

main()

解决方法

这只是一个错字，您在 draw_window 函数中写的是Bird.draw(bin)而不是Bird.draw(win)。

此功能应如下所示：

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