我刚开始学习批处理，并认为最好的学习方法就是给自己一个项目。我正在尝试一个基于文本的RPG，并挂在一个地方。我试图在一个“对话”中嵌套多个IF-IF NOT DEFINED和IF-ELSE“问题”。
if "%choice18%"=="talk hag" (
if "%glove%"=="0" (
if "%ketchup%"=="2" (
echo.
echo "AHH! Can it really be ye, Cramforth?" the hag asks. "If it be, then ye wouldn't mind answering a few personal questions bout us to prove it, would ye?" GULP! Art thou ready to answer the hag's personnal questions?
echo.

我遇到的问题是，第一个用户输入变量set /p choice19=在第一次忽略了IF命令。
示例：
:hag
echo.
echo Yes or no:
set /p choice19=
用户输入：是
忽略：if "%choice19%"=="yes" (
转到：if not defined "%choice19%" (
cls
echo.
echo Just answer the hag 'yes' or 'no'. Please?
echo.
goto hag
重定向回：
:hag
echo.
echo Yes or no:
set /p choice19=
用户再次输入：是
这次它遵循正确的命令继续“是”分支。
然而，这对于不会重定向回问题（即if "%choice20%"=="b" (）并结束游戏的结果造成问题。
我回顾了一个类似的问题（Nested IF ( IF ( ... ) ELSE( .. ) ) statement in batch）但是，我注意到它与我的情况略有不同，因为我的变量是定义的。所以，我很茫然。有什么想法吗？
注意：我知道我可以在没有深度嵌套的情况下重构命令来解决问题，只需要GOTO来解决问题：LABELS。我只是想看看是什么导致了这个问题。
