Installation

copy the lib folder into your project at any path

How to use

local LightWorld = require "lib/light_world"

-- create light world
lightWorld = LightWorld({
  drawBackground = drawBackground, //the callback to use for drawing the background
  drawForground = drawForground, //the callback to use for drawing the foreground
  ambient = {55,55,55},         //the general ambient light in the environment
})

function love.draw()
  love.graphics.push()
    love.graphics.translate(x, y)
    love.graphics.scale(scale)
    lightWorld:draw(x,y,scale)
  love.graphics.pop()
end

please see the examples directory to see how it is fully used. also this project can be run to show you the deomnstrations.
