File Reading

[Koba]

@everyone: is there any way to get lua to read from a text file?
if not then, @Shine: have you put any thought into I/O text file reading for LUA yet?

yes, it is fully possible to both read and write from files.

Examples:

function ReadSystemSettings()

file = io.open("settings.cfg", "r")
Pointer.x_pos = file:read("*l")
Pointer.y_pos = file:read("*l")
file:close()
end

function SaveSystemSettings()
ToggleUSB(false)
file = io.open("settings.cfg", "w")
file:write(Pointer.x_pos .. "\n")
file:write(Pointer.y_pos)
file:close()
end

so, what i want to read and write a file for is for a sorta of save state in my game, say you buy a object, then the script will write to the file "object1 = BOUGHT" and then when you turn the game off, and start it again, the object will already be purchased. stuff like that, so it is possible to read variables and stuff from a text file? or is it just basic read/write simple text so far?

You can read from files into variables if that's what you mean...

How you implement it is up to you, since there are many differnets ways to do that.

You can read/write text, but arbitrary variable structures are possible, too. See http://www.lua.org/pil/index.html#12 for an advanced method or http://www.luaplayer.org/gallery/snake.lua.txt for a quick and dirty hack :-)

can the save/load feature read and write to anything other than .txt
I can save to .txt but when I try to save .cfg, it writes to my system.lua file
