如何解决批处理文件在if语句中不断崩溃
我正在制作一个简单的文字游戏。一切正常，直到到达if语句为止。我不知道我在做什么错。
@echo off
title Text Adventures
echo "What is your name?"
set /p name=
echo "That was a bad crash. Are you hurt,%name%?"
echo.
echo Y/N
set /p answer=
if %answer% equ y goto hurt
:hurt
echo.
echo "I see. That's a gnarly gash you've got there!"
解决方法
在这里，我将其重写为使用函数的形式，并使用我提供给原始帖子的建议作为注释。
您知道我错误地认为您有使用标签的目的，但是鉴于问题的解决方式，我认为您可以很好地避免打扰他们。
这里是无标签版本：
@(SETLOCAL
echo off
title Text Adventures
)
CALL :Main
( ENDLOCAL
ECHO. The Script Ended!
PAUSE
EXIT /B
)
:Main
set /p "name=What is Your Name?"
ECHO.
CHOICE /M "That was a bad crash. Are you hurt,%name%?"
If %ERRORLEVEL% equ 1 (
echo.
echo "I see. That's a gnarly gash you've got there!"
) ELSE (
echo.
echo "Oh Good!"
)
PAUSE
GOTO :EOF
这里是标签版本。 （我删除了注释，解释了它的工作原理以及为什么有代码，所以对您而言它不会那么混乱。）
@(SETLOCAL
echo off
title Text Adventures
)
CALL :Main
( ENDLOCAL
ECHO. The Script Ended!
PAUSE
EXIT /B
)
:Main
set /p "name=What is Your Name?"
ECHO.
CHOICE /M "That was a bad crash. Are you hurt,%name%?"
If %ERRORLEVEL% equ 1 (
CALL :Hurt
) ELSE (
CALL :NotHurt
)
PAUSE
GOTO :EOF
:Hurt
echo.
echo "I see. That's a gnarly gash you've got there!"
GOTO :EOF
:NotHurt
echo.
echo "Oh Good!"
GOTO :EOF
对于这种事情，我更喜欢使用选择，并且经常使用菜单宏，该宏将所选选项作为字符串返回到变量option
下面是一个shell脚本，它演示了我经常使用的几个宏的用法。

菜单宏会为其提供的每个参数构建一个选择列表，使用子字符串修改来遍历36个字符的选择列表以构建最终选择选项-意味着支持36个菜单选项。
更新
已添加一个附加示例，以显示一种使用选择项显示输出或采取措施而无需进行条件测试的方法。使用List/D/V宏为选项定义值，可以直接扩展所选的OPTION。在该示例中，仅显示输出，但是可以分配包含简单命令（如Set，Goto或call之类的值）以对所选菜单选项执行特定操作。
我忘了添加暂停
