Question

我正在制作游戏，我想要一个只出现一次的个性化用户名选项。

以下是一个例子：

@echo off
:onetime
echo please enter a username
echo.
set /p newuser=%newuser%:
echo %newuser%> cfg.txt
goto menu


:menu
for /f "tokens=* delims=" %%x in (cfg.txt) do echo %%x
cls
...

我正在试图弄清楚如何制作：一次发生一次，以便将用户名发送到cfg.txt

任何人都知道怎么做？

Answer 1

我已经清理了你的代码并提供了一份完整的工作脚本，并注明了你将游戏代码放在哪里。

虽然此代码不需要延迟扩展，但我已将其放在脚本中，就像在原始脚本中一样。

请注意我选择的变量名称，因为它们在多个位置使用。

我试图用关于它正在做什么的信息来评论代码，如果需要，我会碰巧进一步解释。

如果可以的话，我想在你完成游戏时真正玩游戏。：）

希望有所帮助。

Answer 2

尝试检查文件是否存在：

@echo off
:onetime
setlocal enableDelayedExpansion
if not exist "cfg.txt" (
 echo please enter a username
 echo.
 set /p newuser=%newuser%:
 echo !newuser!> cfg.txt
 goto menu
)


:menu
for /f "tokens=* delims=" %%x in (cfg.txt) do echo %%x
cls

制作批处理文件只做一次
