What is the problem ?

LÖVE ask to use functions love.{load,update,draw,...}

Sample :

function love.load()
	-- code
end

function love.update(dt)
	-- code
end

function love.draw()
	-- code
end

The problem is it's not easy to setup lot of features inside only one functions. Each kind of feature needs to use one or more love callbacks.

Why using love modular ?

It's usefull to make module, and be able to re-used them easily. It's also allow to enable/disable module dynamically.

Documentation

Simple use

Sample of module :

local t
local function load()
	require("love.graphics")
	t = 0
end
local function update(dt)
	t = t + dt
end
local function draw()
	love.graphics.print("hello"..tostring(t), 0, 0)
end
return {
	__love = {
		default = {
			load = load,
			update = update,
			draw = draw,
		},
	},
}

Advanced Use

Catching Signals

stop signal

Sample to stop the defaults keypressed events (but the pre or post keypressed events will still worked)

local modular = require("modular")
local signal_stop = modular.signal_stop

return {
	__love = {
		default = {
			keypressed = function(key)
				return signal_stop
			end,
		},
	},
}

stop all signals

Sample of way to drop all keypressed events.

local modular = require("modular")
local signal_stop_all = modular.signal_stop("all")

return {
	 __love = {
		pre = {
			keypressed = function(key)
				return signal_stop_all
			end,
		},
	},
}

intercept a signal

Sample of interception : replace the f1 by escape

local modular = require("modular")
local signal_continue = modular.signal_continue

return {
	__love = {
		pre = {
			keypressed = function(key)
				if key == "f1" then
					return signal_continue("escape")
				end
			end,
		},
	},
}

Note: the intercepted signal will be propaged to all others level (pre, default and post) callbacks.

• More documentation and samples
• Release it ! Write a thread on the love2d.org forum about it
