您好，我正在使用pygame进行图形冒险/角色扮演。 有没有办法用pygame制作NPC，并能够与它们进行交互，就像对话一样？ 我一直在互联网上搜索，但没有有用的结果。如果有人可以帮助我，那就太好了。
这是主要代码。

在1960年代，有一个简单的类似对话的处理程序，名为Eliza。从那时起，发生了许多变化和变体，它们被称为“聊天机器人”。也许您的NPC可以与玩家进行类似Eliza的对话？可能需要对这类自然文本处理器进行一些研究。
但是，如果您的意思是仅从[（a），（b），（c）]类型列表中选择对话主题，则通常将这些对话映射到选择图中。您读过制作choices to change the narrative的故事吗？这些是简单的选择图。您可以将它们绘制在一张纸上，然后将它们编码为数据结构，例如python字典。每个选项将移动到图中的另一个节点。也许他们也回过头来。
