我试图用python制作一个游戏，其中一个角色射击敌人的入射波。我有一个子弹列表，一个敌人列表＆＃39;尸体，以及他们的头脑清单。出于某种原因，当我射击并且子弹与敌人发生碰撞时，有两种结果之一。我得到一个错误：＆＃34;列表索引超出范围＆＃34;或者被删除后产生的所有敌人，最终我得到同样的错误。我该如何解决？此外，我每次拍子弹时都试图让图像出现（枪口闪光灯），而且我遇到了麻烦。任何人都可以帮忙

答案 0 :(得分：1)
您正在迭代列表中的元素。这是不允许的，因为您正在减少列表的长度，同时尝试访问不再有效的索引处的列表元素。因此你得到IndexError。
请查看此问题Remove items from a list while iterating。如果此修复程序没有解决此问题，您应该修复代码，并针对其他问题使用最小的正确工作示例提出新问题。
