pygame 碰撞报错

Question

在

import pygame as pg
from pygame.locals import *
from random import randint

height = 400
weigh = 600
goods_h = 100
goods_w = goods_h*0.92

red_h = red_w*1.4

yb_w = yb_h*1.72

pg.init()

object_group = pg.sprite.Group()
def change(roles_address:str,w:'int > 0',h:'int > 0'):
         role = roles_address
         roles = pg.image.load(role)
         roles = pg.transform.smoothscale(roles,(w,h))
         pos = roles.get_rect()
         if roles_address != 'pygame图片素材\背景.jpg' or roles_address != 'pygame图片素材\财神爷.png':
                  object_group.add(roles)
         return roles

         #碰撞
         if pg.sprite.spritecollide(goods,object_group,False,None):
                  print(pg.sprite.spritecollide(goods,object_group,False,None))

         key = pg.key.get_pressed()
         if key[K_a] and pos_g.left >= 0:pos_g.x -= 5
         if key[K_d] and pos_g.right <= weigh:pos_g.x += 5

         pg.display.update()
         time.sleep(0.05)

中的#碰撞 报错
报错信息：

Traceback (most recent call last):
  File "C:\Users\Administrator\AppData\Roaming\Python\Python38\site-packages\pygame\sprite.py", line 449, in add
    self.add(*sprite)
TypeError: add() argument after * must be an iterable, not pygame.Surface

During handling of the above exception, another exception occurred:

    back = change('pygame图片素材\背景.jpg',weigh,height)

    object_group.add(roles)

    sprite.add_internal(self)
AttributeError: 'pygame.Surface' object has no attribute 'add_internal'

我想将精灵和精灵组进行碰撞判断
注：pygame库被作者修改过，增加了退出函数并将解码方式改为UTF-8

你的roles变量是一个Surface，要想加到组里的话需要定义成Sprite对象
