'int'对象没有属性'mouse_x'指向self.mx

Question

我有一个鼠标精灵，每次游戏循环迭代时都会更新鼠标的x和y位置，但是我不太确定下面的错误消息是什么：“似乎'int'对象没有属性'mouse_x'像是将“自我”作为int对象，而“ mouse_x”作为其属性？]

import pygame


class mouse_sprite(pygame.sprite.Sprite):


    def __init__(self, x, y, screen):
        self.screen = screen
        self.mouse_x = x
        self.mouse_y = y

        self.update_rect(self.mx, self.my)

    def update_rect(self):
        self.rect = pygame.Rect(self.mouse_x, self.mouse_y, 1, 1)

    def update(self, x=None, y=None, screen=None):
        **#ERROR: 'int' object has no attribute 'mouse_x' Line 24: self.mouse_x = x**
        if x is not None:
            self.mouse_x = x

        if my is not None:
            self.mouse_y = y

        if screen is not None:
            self.screen = screen

        self.update_rect()

mouse = mouse_sprite
mx, my = pygame.mouse.get_pos()
mouse.update(mx, my)

您没有创建新对象。您只是在像静态方法一样调用类方法
