AttributeError:'class'对象没有属性'rect' [英] AttributeError: 'class' object has no attribute 'rect'

问题描述

我上了这堂课:

class Comet(pygame.sprite.Sprite):
def ___init___(self):
    super().__init__()
    self.image = pygame.Surface((100,250))
    self.image.fill(cometL)
    self.rect = self.image.get_rect()
    self.rect.y = 800
    self.rect.x = 100
def update(self):
    self.rect.y -= 1+2*speed
def reset(self):
    self.rect.x = randint(0,700)
    self.rect.y = randint(1000,2000)

我尝试在这里使用它:

    comet1  = Comet()
    comet1.rect.x = 100
    comet1.rect.y = 800
    comets.add(comet1)

但是当我这样做时，我会收到此错误:

But when i do I get this error:

文件"，第36行，在comet1.rect.x = 100

File "", line 36, in comet1.rect.x = 100

AttributeError:"comet"对象没有属性"rect"

AttributeError: 'comet' object has no attribute 'rect'

即使上课了(我想我对上课还是有点陌生​​的)

Even though the class does (I think, i'm kinda new to classes)

推荐答案

您对 __ init __ 的定义错误.您使用了三个下划线( ___ init ___ )，因此在实例化类时不会调用此函数.

Your definition for __init__ is wrong. You used three underscores (___init___), so this function is not called during instantiation of the class.

这意味着不会调用 self.rect = self.image.get_rect()行，因此没有 rect 属性.

This means that the line self.rect = self.image.get_rect() isn't called and so there is no rect attribute.
