Question

我正在尝试制作游戏，代码中也有一些问题。我不知道为什么我的代码给出错误。错误是

“ AttributeError：'BarreraControlable'对象没有属性'abajo'”

class BarreraControlable(pygame.sprite.Sprite):

def __init__(self, xInicial, yInicial):
    pygame.sprite.Sprite.__init__(self)

    self.image = pygame.image.load("animaciones/barrera.png") #barrera.png? .png necesario
    self.rect = self.image.get_rect()
    self.rect.x = xInicial
    self.rect.y = yInicial
    self.subir = -8
    self.bajar = 8
    self.incremento = self.bajar


def lecturaEventos(self):
    event = pygame.event.poll()
    self.abajo = False
    self.arriba = False

    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_DOWN:
            self.abajo = True
        elif event.key == pygame.K_UP:
            self.arriba = True
    elif event.type == pygame.KEYUP:
        self.abajo = False
        self.arriba = False

def ejecutaPaso(self):
    if self.abajo == True:
        self.rect.y += self.incremento
    elif self.arriba == True:
        self.incremento = self.bajar
        self.rect.y += self.incremento

def update(self):
    self.ejecutaPaso()

您的class TopLevelJobViewSet(ModelViewSet): permission_classes = (IsOwner,) serializer_class = TopLevelJobSerializer queryset = TopLevelJob.objects.all() filter_backends = [IsOwnerFilter, DjangoFilterBackend, RelatedOrderingFilter] filter_class = TopLevelJobFilter ordering_fields = '__all__'是在方法self.abajo中创建和分配的。在致电lectureEventos()或lectureEventos()之前，请确保已致电ejectutaPaso()。

或者，如果您不希望在方法中初始化所有属性，则可以在构造函数中初始化所有属性。

如何在一个功能之间共享属性
