大佬求解，为什么我照着视频敲的代码，碰撞检测时只有一个小球在动，其他4个都在原地鬼畜啊

import pygame
import sys
from pygame.locals import *
from random import *
class Ball(pygame.sprite.Sprite):
def __init__(self,image,position,speed,bg_size):
super().__init__()
self.image = pygame.image.load(image).convert_alpha()
self.rect = self.image.get_rect()
self.rect.left ,self.rect.top = position
self.speed = speed
self.width,self.height = bg_size
self.radius = self.rect.width / 2
def move(self):
self.rect = self.rect.move(self.speed)
if self.rect.right < 0:
self.rect.left = self.width
elif self.rect.left > self.width:
self.rect.right = 0
elif self.rect.bottom < 0:
self.rect.top = self.height
elif self.rect.top > self.height:
self.rect.bottom = 0
def main():
pygame.init()
ball_image = '1.png'
bg_imagre = '2.png'

bg_size = width,height = 1024,681
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption('play the ball')

for i in range(5):
position = randint(0,width-100),randint(0,height-100)

ball = Ball(ball_image,position,speed,bg_size)
#检测球生成时是否发生碰撞
while pygame.sprite.spritecollide(ball,group,False,pygame.sprite.collide_circle):

screen.blit(background,(0,0))
for each in balls:
each.move()
screen.blit(each.image,each.rect)
