Config Files

Introduction

If a file called conf.lua is present in your game folder (or .love file), it is run before the LÖVE modules are loaded. You can use this file to overwrite the love.conf function, which is later called by the LÖVE 'boot' script. Using the love.conf function, you can set some configuration options, and change things like the default size of the window, which modules are loaded, and other stuff.

love.conf

The love.conf function takes one argument: a table filled with all the default values which you can overwrite to your liking. If you want to change the default screen size, for instance, do:

function love.conf(t)
    t.screen.width = 1024
    t.screen.height = 768
end

If you don't need the physics module or joystick module, do the following.

function love.conf(t)
    t.modules.joystick = false
    t.modules.physics = false
end

Setting unused modules to false is encouraged when you release your game. It reduces startup time (slightly) and reduces memory usage (slightly). Here is a full list of options and their default values:

 
function love.conf(t)
    t.modules.joystick = true   -- Enable the joystick module (boolean)
    t.modules.audio = true      -- Enable the audio module (boolean)
    t.modules.keyboard = true   -- Enable the keyboard module (boolean)
    t.modules.event = true      -- Enable the event module (boolean)
    t.modules.image = true      -- Enable the image module (boolean)
    t.modules.graphics = true   -- Enable the graphics module (boolean)
    t.modules.timer = true      -- Enable the timer module (boolean)
    t.modules.mouse = true      -- Enable the mouse module (boolean)
    t.modules.sound = true      -- Enable the sound module (boolean)
    t.modules.physics = true    -- Enable the physics module (boolean)
    t.console = false           -- Attach a console (boolean, Windows only)
    t.title = "Untitled"        -- The title of the window the game is in (string)
    t.author = "Unnamed"        -- 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 = 600       -- The window height (number)
    t.screen.width = 800        -- The window width (number)
    t.version = 0               -- The L�VE version this game was made for (number)
end

Note that you can't disable love.filesystem; it's mandatory. The same goes for the love module itself.
