属性错误：“模块”对象没有属性 - 无需更多帮助

Question

我是编程新手，我的代码中不断出现此错误。这是我的完整代码： 导入系统、pygame、数学； 从 pygame.locals 导入 *； 从系统导入退出 pygame.init()

blk = pygame.Color(0,0,0)
BG = ('BG.png')
pygame.init()
screen = pygame.display.set_mode((800, 600))
#mousec = pygame.image.load(mouse_c).convert_alpha()
B_G = pygame.image.load(BG).convert_alpha()
clock = pygame.time.Clock()
pygame.mouse.set_visible(False)
fpsclock = pygame.time.Clock()
Shrek = pygame.image.load('SHORK.png').convert_alpha()
Shrek_Rect = Shrek.get_rect()

class Shork(pygame.sprite.Sprite):

  def __init__(self):
    pygame.sprite.Sprite.__init__(self)
    self.image = pygame.image.load('SHORK.png')
    screen = pygame.display.get_surface()
    self.x = 62
    self.y = 50
    self.direction = "down"

  def Moving(self):

    if self.direction == "right":
     self.x += 2
    elif self.direction == "left":
     self.x -= 2
    elif self.direction == "down":
     self.y += 2
    elif self.direction == "up":
     self.y -= 2

  def Path(self): # Moves the "SHORK" image on the screen

    if self.x == 62 and self.y == 538:
     self.direction = "right"

    if self.x == 246 and self.y == 538:
     self.direction = "up"

    if self.x == 246 and self.y == 366:
     self.direction = "left"

    if self.x == 176 and self.y == 366:
     self.direction = "up"

    if self.x == 176 and self.y == 114:
     self.direction = "right"

    if self.x == 530 and self.y == 114:
     self.direction = "down"

    if self.x == 530 and self.y == 366:
     self.direction = "left"

    if self.x == 460 and self.y == 366:
     self.direction = "down"

    if self.x == 460 and self.y == 538:
     self.direction = "right"

    if self.x == 644 and self.y == 538:
     self.direction = "up"
    if self.y == 0:
     sys.exit()

Shork = Shork()

Run = True

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEBUTTONDOWN and event.button == 1:
            print("test1")
        elif event.type == MOUSEBUTTONDOWN and event.button == 3:
            print("test3")
    while Run:
        fpsclock.tick(60)

        for event in pygame.event.get():

         if event.type == pygame.QUIT:
            Run = False
    pos = pygame.Shrek_Rect
    angle = 360-math.atan2(pos[1]-300,pos[0]-400)*180/math.pi
    rotimage = pygame.transform.rotate(B_G,angle)
    screen.fill(blk)
    Shork.Moving() 
    Shork.Path()
    screen.blit(Shork.image, (Shork.x, Shork.y))
    pygame.display.update()
    rect = rotimage.get_rect(center=(400,300))
    screen.blit(rotimage,rect)
    pygame.display.update()
    #Rotates the BG image on the screen

这是我的错误发生的地方：

    pos = pygame.Shrek_Rect
    angle = 360-math.atan2(pos[1]-300,pos[0]-400)*180/math.pi
    rotimage = pygame.transform.rotate(B_G,angle)

错误提示：

Traceback (most recent call last):
  File "turny.py", line 96, in (module)
    pos = pygame.Shork_Rect
AttributeError: 'module' object has no attribute 'Shrek_Rect'

程序的重点是当 BG 图像在屏幕上移动时将其旋转到 SHORK 图像。我从一些旧代码中重新调整了这段代码的用途，这些代码旨在使 BG 跟随光标。我被困在这个错误上，无法弄清楚。

此外，如果您将 Shrek_Rect 替换为错误为 BG 的“mouse.get_pos()”，则会跟随玩家鼠标。

您的问题与命名空间有关。 Shrek_Rect 没有在 pygame 中定义，它是在本地命名空间中定义的。

尝试改变：

pos = pygame.Shrek_Rect

收件人：

pos = Shrek_Rect
