Accessing Data from the conf.lua file

[The_A_Drain]

Hi guys, just started having a fiddle around with LUA and I'm putting together a quick template project for use in game jams and the like, I've figured out how to get the screen size from graphics but I'd like the default menu page to display the games title, is there a way of simply pulling the title that has been set in conf.lua?

I had a search on the forums but turned up a lot of information about other things to do with conf.lua.

cheers

Ahh, can't believe I didn't see that.

Thanks so much.

You could also just declare global variables in the conf.lua files, I think. It is possible, though, that LÖVE does not run the two files with the same Lua_state.
Anyways, this is how you'd do it:

Code: Select all

-- conf.lua
S_WIDTH, S_HEIGHT = 800, 600
S_TITLE = "Test Window"

function love.conf(ct)
  ct.screen.width, ct.screen.height = S_WIDTH, S_HEIGHT
  ct.title = S_TITLE
end

Code: Select all

-- main.lua
local w, h, title

function love.load()
  w, h, title = S_WIDTH, S_HEIGHT, S_TITLE
end

Thanks for the info Anickyan, I might give that a try later. I'm very new to LUA coming from C#/C++ it's very different.

Another alternative would be:
If your conf.lua file is:

Code: Select all

function love.conf(t)
    t.title      = "mouse drag image"   -- The title of game window    (string)
    t.author   = "Ref"                         -- The author of the game       (string)
    t.screen.fullscreen = false           -- Enable fullscreen                 (boolean)
    t.screen.vsync       = true            -- Enable vertical sync             (boolean)
    t.screen.fsaa         = 0                 -- The number of FSAA-buffers (number)
    t.screen.height      = 512             -- The window height               (number)
    t.screen.width       = 512             -- The window width                (number)
    t.version                = "0.8.0"        -- The LOVE version                 (string)
    t.console                = false          -- Enable console                     (boolean)
    end

You can access the values in con.lua in your main.lua via:

Code: Select all

local temp    = {}
temp.screen = {}
love.conf( temp)
title = temp.title
width = temp.screen.width
height = temp.screen.height
...

Actually, this would be the easiest, I think:

conf.lua

Code: Select all

configTable = {} -- use any variable name

function love.conf(t)
  t.screen.width = 800
  t.screen.height = 600
  t.title = "Test Window"
  configTable = t
end

main.lua

Code: Select all

function love.load()
  local screenWidth = configTable.screen.width -- access all of the values inside the table
end

That basically has the same spirit as Ref's snippet, though.

Yeah... But for a Lua beginner, t might be easier to understand ó_ó
