Pygame碰撞不起作用

对于我的计算项目，我需要制作某种应用程序或游戏。我决定我会制造太空侵略者。我已经设法使基本工作，精灵会产卵，我可以移动玩家，敌人从屏幕的顶部落下，背景和音乐正常工作，但碰撞不能正常工作。当角落接触或两个角之间的中点接触时，它会正常工作，程序关闭。但是如果角落/中点不碰，那么精灵就会穿过对方。任何帮助将非常感激。这里是代码：Pygame碰撞不起作用

任何帮助将是伟大的，谢谢。

功能pygame.sprite.collide_rect不适用于直接使用。它旨在传递到 '主' 碰撞功能

pygame.sprite.spritecollide()
pygame.sprite.groupcollide()
pygame.sprite.spritecollideany()

你的情况，你想pygame.sprite.spritecollideany：

col = pygame.sprite.spritecollideany(player, mobs) 
if col: 
    sys.exit()

此功能在返回一个0与player相撞。
