让这个战斗引擎工作吗？

Question

目前我正忙于Zed Shaw的练习36 LPTHW，我真的需要一些帮助来弄清楚为什么我制造的这个战斗引擎不能工作。我重写了之前的一次尝试，试图让它更清楚。以下是我相信的相关代码，如果太长，我很抱歉，但作为一个新手，我不完全确定什么是相关的。在

Answer 1

以下是程序流程的简要说明：

character_gen调用buy_weapon，后者调用weapon_code，后者调用{}，后者调用{}。在combat_engine内，一旦你将敌人的生命值降低到零或以下，它将执行第二个elif分支，其第一个语句是break。此语句导致combat_engine的while循环终止。combat_engine结束，因此控制返回barracks。barracks结束，因此控制返回weapon_code。weapon_code结束，因此控制返回buy_weapon。buy_weapon执行调用weapon_code后发生的任何代码，即以下行：

raw_input("""
Your current weapon is now a %s. Press Enter To Continue
""" % current_weapon)

buy_weapon结束，控件返回character_gen。character_gen结束，控制返回主模块。主模块结束，程序终止。这就解释了为什么你会得到你所得到的输出。在

至于解决问题，我建议两件事：

1. 阅读break以确认它正在做你认为它在做的事情。break之后的任何内容，例如print "You defeated the %s! Great Job!"在任何情况下都不会执行。在
2. 有关代码的整体流程，请查看State Machines。营房/库存等不是功能，而是各自的状态，由用户输入决定转换到哪个状态。现在的方法是，在大约500个操作之后，您将遇到堆栈溢出。在
