python鼠标碰撞_python入门到实践里的飞机游戏，在添加子弹与外星人碰撞之前一切正常，但添加碰撞后错误...

题目描述

不加pygame.sprite.groupcollide()代码，运行一切正常没有问题

加了pygame.sprite.groupcollide()代码运行时按下空格就发生错误了。不按空格就正常运行

Traceback (most recent call last):

File "alien_invasion.py", line 41, in

run_game()

File "alien_invasion.py", line 33, in run_game

gf.update_bullet(bullets,aliens)

File "G:\python_work\alien_invasion\game_functions.py", line 115, in update_bullet

cllisions = pygame.sprite.groupcollide(bullets,aliens,True,True)

spritecollide = sprite.rect.colliderect

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

题目来源及自己的思路

题目时python编程入门到实践的例题，自己打的和书上没什么差别
