love.conf

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 window size, for instance, do:

function love.conf(t)
    t.window.width = 1024
    t.window.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 (especially if the joystick module is disabled) and reduces memory usage (slightly).

Note that you can't disable love.filesystem; it's mandatory. The same goes for the love module itself. love.graphics needs love.window to be enabled.

Current Configuration File

Here is a full list of options and their default values for LÖVE 0.10.1 and 0.10.2:

function love.conf(t)
    t.identity = nil                    -- The name of the save directory (string)

    t.window.resizable = false          -- Let the window be user-resizable (boolean)
    t.window.minwidth = 1               -- Minimum window width if the window is resizable (number)
    t.window.minheight = 1              -- Minimum window height if the window is resizable (number)
    t.window.fullscreen = false         -- Enable fullscreen (boolean)
    t.window.fullscreentype = "desktop" -- Choose between "desktop" fullscreen or "exclusive" fullscreen mode (string)
    t.window.vsync = true               -- Enable vertical sync (boolean)
    t.window.msaa = 0                   -- The number of samples to use with multi-sampled antialiasing (number)
    t.window.display = 1                -- Index of the monitor to show the window in (number)
    t.window.highdpi = false            -- Enable high-dpi mode for the window on a Retina display (boolean)
    t.window.x = nil                    -- The x-coordinate of the window's position in the specified display (number)
    t.window.y = nil                    -- The y-coordinate of the window's position in the specified display (number)
 
    t.modules.audio = true              -- Enable the audio module (boolean)
    t.modules.event = true              -- Enable the event module (boolean)
    t.modules.graphics = true           -- Enable the graphics module (boolean)

    t.modules.timer = true              -- Enable the timer module (boolean), Disabling it will result 0 delta time in love.update
    t.modules.touch = true              -- Enable the touch module (boolean)
    t.modules.video = true              -- Enable the video module (boolean)
    t.modules.window = true             -- Enable the window module (boolean)
    t.modules.thread = true             -- Enable the thread module (boolean)

Flags

identity

This flag determines the name of the save directory for your game. Note that you can only specify the name, not the location where it will be created:

t.identity = "gabe_HL3" -- Correct
t.identity = "c:/Users/gabe/HL3" -- Incorrect

Alternatively love.filesystem.setIdentity can be used to set the save directory outside of the config file.

version

Available since LÖVE 0.8.0
This flag is not supported in earlier versions.

t.version should be a string, representing the version of LÖVE for which your game was made. It should be formatted as "X.Y.Z" where X is the major release number, Y the minor, and Z the patch level. It allows LÖVE to display a warning if it isn't compatible. Its default is the version of LÖVE running.

console

Determines wether a console should be opened alongside the game window (Windows only) or not. Note: On OSX you can get console output by running LÖVE through the terminal.

accelerometerjoystick

Available since LÖVE 0.10.0
This flag is not supported in earlier versions.

Sets whether the device accelerometer on iOS and Android should be exposed as a 3-axis Joystick. Disabling the accelerometer when it's not used may reduce CPU usage.

externalstorage

Available since LÖVE 0.10.1
This flag is not supported in earlier versions.

Sets whether files are saved in external storage (true) or internal storage (false) on Android.

gammacorrect

Available since LÖVE 0.10.0
This flag is not supported in earlier versions.

Determines whether gamma-correct rendering is enabled, when the system supports it.

window

Available since LÖVE 0.9.0
These flags are not supported in earlier versions.

It is possible to defer window creation until love.window.setMode is first called in your code. To do so, set t.window = nil in love.conf (or t.screen = nil in older versions.) If this is done, LÖVE may crash if any function from love.graphics is called before the first love.window.setMode in your code.

The t.window table was named t.screen in versions prior to 0.9.0. The t.screen table doesn't exist in love.conf in 0.9.0, and the t.window table doesn't exist in love.conf in 0.8.0. This means love.conf will fail to execute (therefore it will fall back to default values) if care is not taken to use the correct table for the LÖVE version being used.
