问题描述
我正在创建简单的游戏，我在其中扮演飞机并躲避火箭。
我想做“屏障”，我可以用键盘激活它。
当火箭撞到障碍物时，这枚火箭应该被杀死。
我试过kill()，但没有用，我也试过从精灵组中删除等等。
我真的很感谢你的帮助，因为我被卡住了，再见
这是我的代码：

解决方法
你杀错了敌人。 enemy 变量包含一个随机敌人，但不包含正在碰撞的敌人。 pygame.sprite.spritecollideany() 返回碰撞的敌人 Sprite：
collided_enemy = pygame.sprite.spritecollideany(barrier,enemies):
if collided_enemy != None:
collided_enemy .kill()
或者，您可以使用 pygame.sprite.spritecollide() 并将 dokill 参数设置为 True：
dokill 参数是一个布尔值。如果设置为 True，所有发生碰撞的 Sprite 将从 Group 中移除。
pygame.sprite.spritecollide(barrier,enemies,True)
