【问题描述】：
我整天都在试图弄清楚这一点，并搜索了无数帖子。我试图弄清楚如何让我的精灵执行攻击动画，但实际上没有关于如何在线执行此操作的文档或信息。如果我向右移动，我已经将它带到了他将执行旋转攻击动画的位置，但是经过这么多次旋转后，游戏将崩溃并显示“列表索引超出范围”。此外，如果角色静止不动，按攻击键“w”绝对没有任何作用。我已经包含了我的代码的副本。任何帮助将不胜感激。

【问题讨论】：
-
有plenty of examples 其他人如何解决它。 SO 上还有关于如何为精灵设置动画的资源。你看过哪些？
-
我一直在查看文档，包括 pygame 文档中关于移动图像的教程。我也尝试过实现 youtube 教程中的代码，并根据我的需要专门定制它们，但他们正在制作不同类型的游戏。我搜索了有关如何无限迭代列表的帖子。如何在 python 中重复列表。读到 image.blit 不能 blit 列表，尽管 image.blit 很好地对我的行走图像列表进行了 blit。也许我只是不知道要寻找什么？我可以向你保证，如果你怀疑，我不会偷懒并试图找到一个简单的答案。
-
如果你想轮换列表，你可以做
walkLeft[walkCount % len(walkLeft-1)]?让它自己循环。假设它是具有列表开始/结束的完美动画，并且您不必向后执行动画。 （另外，不是说你很懒嘿嘿。但我认为解决方案比问题更简单） -
再次您好，感谢您的回复。抱歉，如果我之前的评论出错了。我真的很难处理这个问题，我不知道要寻找什么，因为我是 pygame 和一般编程的新手。我会研究你的建议，但似乎我的问题不在于代码的步行部分，而更多的是攻击动画试图与步行动画同时发生，攻击动画似乎用完了列表中的图像，而我仍然按下键并且游戏崩溃。
-
呵呵，不用担心 :) 哦，我想我们需要看看有问题的精灵。因为我不确定你应该如何为你的步行+攻击动画使用两个单独的图像。通常这些是相同的图像对象。这种方式通常更容易解决。因为将两张图像拼接在一起 - 相比之下，如果您手动进行，则非常困难。
