我正在为学校课程开发一款小型目标射击游戏。经过大约一个半小时的迭代和测试，我陷入了僵局。如果您看到下面的代码，我已经使用列表进行了创建，以便当子弹击中目标时将其从列表中删除，不再使用“ pygame.draw.rect”进行打印，但这似乎要困难得多。我使用OOP而不是一次性功能使这些目标成为现实。我尝试过复制带有目标的项目符号列表，将“ IF”语句放在相同的位置，等等。但是最终我得到了相同的结果，即目标被击中并打印了“ hit”。子弹消失，但目标没有。我只使用该语言大约一个月，所以尽管我已经习惯了这种语言，但我仍然不是专家，我真的在这里陷入了僵局。任何帮助将不胜感激。可能是我不得不重新考虑自己的方法并大幅度更改代码的情况，但也许您可以看到一些我看不到的东西。感谢您提供的任何帮助。 （对于代码的混乱情况，很抱歉，它经过了许多更改和迭代。还请注意，我目前仅编码以在target_1上对其进行测试，以节省时间）

您的代码中有一些小错误。我认为目标并没有消失，因为all_targets_keep列表中出现了一些问题。似乎代码正在将目标重新添加到“保留”列表中，无论是否被击中。
