How do I make a save file?

[Luigi master]

omg first post
For my game, I want to make a save file.
I already have this code:

Code: [Select]

(
  echo %Name%
  echo %HP%
  echo %LV%
) > %Name%Save.lsavto save.
How do I make the batch file read each line?
Please help!

The > redirection operator has an opposite operator the < to pass from file back to the variable.

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

Okay, let me rephrase.
How do I make it read every line?
I want this:

Save File:
1234
4321
1324

Now in the batch file:
(Sets the variables to the line)
%Line1% = 1234
%Line2% = 4321
%Line3% = 1324

There are many ways to skin this cat:   using this format when creating the save file allows you to rename the .lsav file and add a .bat extension, which you call and rename the file back again.  All your variables are set.

Code: [Select]

(
  echo set name=%Name%
  echo set HP=%HP%
  echo set LV=%LV%
) > %Name%Save.lsav

I'm not sure this topic was resolved, or if the OP found it helpful. To reiterate what Foxidrive said with an example:




:save
(
echo %health%
echo %bees%
)>textfile.txt


:load
(
set /p health=
set /p bees=
)<textfile.txt

Use "Echo" to set the variable, "set /p" to load it. Also NOTE the direction of the carrots. ">" to save, "<" to load. Hope that helps!
