Lua Coding Question

[Glynnder]

I decided to place this here as i feel its a better place than the luahelpthread.

If i had a settings.ini file, that worked fine but i wanted to make a graphical menu so they can change it on the settings how would i load a line of that code, alter it, save it on the same file, then load it again.

i basically need to know how to load and save certain lines from a text file


sorry plz delete the other one

well, at least you could do 15% of what i needed lol!

to read

file = io.open("testRead.txt", "r")
ourtext = file:read()
file:close()

*testRead.txt is your text file
*ourtext is the text from the file

to save (write) to a file

file = io.open("testRead.txt","w")
file:write("hello")
file:close()

*Again testRead.txt is the file
*"hello" is the text to write to a file

All this is from EvilMana.com (it goes into more detail aswell)

i know that, thats pretty basic, but i wanted just to load the whole thing but only alter certain lines

so i could have like

loadlibBase at start = ON
and if they click left/right it goes to
loadlibBase at start = OFF

and in the file its goin from
libbase=true
to
libbase=false

and the same happens with every line of that file.

i just dont wanna have to make a seperate file for each option.

You load the whole thing, change the line, then save the whole thing.

You can ready the file line by line, but there is no pre-set function to just change 1 line.

[Glynnder]

Go here and read this tutorial by Evilmana (PSPMillionaire):

I would use: file.read("*l") inside a for loop with a table or if there are only a few lines something like this:
loadlibBase = file.read("*l")
someOtherSetting=file.rea d("*l")
etc.
for every line in the settings.ini file.

Aslong as you dont change the order of the lines and the amount, it always reads the right lines (i think)
