Hi there, can any of you help me on how to make a game saving system in a .bat RPG game? I am new to this site so sorry if I'm breaking the rules. Thank you very much.

There are multiple ways to do that, just use the search function to look them all up.
You might for example use the following save/load functions (untested):
Code: Select all
@echo off
setlocal enableExtensions disableDelayedExpansion
call :init
call :debug
call :save
set "value1=D"
set "value2=E"
set "value3=F"
call :debug
call :load
call :debug
goto :eof
:debug
set "value1"
set "value2"
set "value3"
echo(===
echo(
goto :eof
:init
set "value1=A"
set "value2=B"
set "value3=C"
goto :eof
:save
>"game.sav" (
set "value1"
set "value2"
set "value3"
)
goto :eof
:load
<"game.sav" (
set /p "value1="
set /p "value2="
set /p "value3="
)
goto :eof

Another method, which avoids having to modify save / load functions every time you add a variable to the script is to use a prefix unique to all variables you wish to save / recover.
Example:
Code: Select all
@Echo off
rem /* predefine your key variables prior to this loop */
:login load existing or create new
Set /P "name=Enter your name: "
If Not "%name%" == "" (
rem /* If character exists; load */
If Exist "%~n0_%name%.bat" (
Call "%~n0_%name%.bat"
rem /* Initialise character save using predefined variables if character new */
) Else ( Call :Save )
rem /* Force Assignment of name variable */
) Else ( Goto login )
===============================================
::: Script body
::: End of Script
Goto :Eof
===============================================
:Save function
(For /F "Delims=" %%G in ('Set #')Do Echo/Set "%%G")>"%~n0_%name%.bat"
Exit /B 0
