Question

所以我试图让它成为如果玩家按下随机键而不是它会回到最后一个标签。如果你按一个键然后按回车键就可以了，但是如果你只按下输入而不是它关闭。请帮忙：

    @echo off
title dragon game
setlocal enabledelayedexpansion

echo Please select an option:
echo.

set /p c=)                

if "%c%" == "1" goto new
if "%c%" == "2" goto load
if "%c%" == "3" goto about
if "%c%" == "4" goto exit

echo 1)Hunting
echo 2)Reading
echo 3)I did my fair share of both
set /p c=)

if "%c%" == "1" (

goto backstory

:youth

echo You are now a youth dragon who must fend for 
echo himself, after your mother died during a raid.
echo.
echo You are resting in a cavern for the time being.
echo However, you are cramped with little space for
echo comfort. You venture out to seek a new lair.
echo.
echo Which direction do you go?
echo -----------------------------------------------
echo 1)North
echo 2)South
echo 3)East
echo 4)West
set /p c=)

if "%c%" == "1" (
set lair=north1
goto northlair1
)
if "%c%" == "2" (

)
if "%c%" == "3" (
set lair=east1
goto eastlair1
)
if "%c%" == "4" (
set lair=west1
goto westlair1
)
goto youth

问题在于最后一个标签

Answer 1

set /p c=)

关闭时没有打开支撑。

Choice /c 1234 /n 
if errorlevel 1 if not errorlevel 2 echo 1 chosen

Answer 2

如果您只是按 Enter ，则假设set /p var=prompt将var设置为 no ，但事实并非如此。它将保持var不变，因此它将保留最后一个条目，因此退出到* lair1（未定义）

要确保您期望的行为，请使用

set "c="
set /p c=)

请注意，此特性可用于设置默认值

set c=6
set /p c=)

如果单独使用 Enter ，

将c保留为6。

尝试阅读call命令。

call :getresponse

将执行子程序＆＃34;：getresponse＆＃34;可能是

:getresponse
set "c=%~1"
set /p C=)
goto :eof

提供您的预期行为，

call :getresponse defaultvalue

会获得响应但允许您单独设置 Enter 的默认值。

括号if语句后批处理文件中的goto函数无法正常工作
