In this tutorial we will cover the basics of using Kadoba's Advanced Tiled Loader. You'll need the Advanced Tiled Loader (in the AdvTiledLoader directory), a mapfile generated by Tiled, and a texturepack in the appropriate location. Let's start with the love.load function:

function love.load()
  loader = require("AdvTiledLoader.Loader")
  loader.path = "maps/" --Change this to wherever your .tmx files are
  map = loader.load("mapfile.tmx") --Change this to the name of your mapfile
  tx = 0
  ty = 0
  scale = 1 -- Adjust zoom with this

Here we load the ATL and tell it where our maps are. We load the maps and initialize our variables. Moving onto love.draw:

function love.draw()
  local ftx, fty = math.floor(tx), math.floor(ty)
  love.graphics.translate(ftx, fty)

In the love.draw function we change tx and ty into integers. This makes for slightly smoother graphics should. We move around the image with love.graphics.translate, and then we call map:draw to actually render it for us.

function love.update(dt)
  if love.keyboard.isDown("up") then ty = ty + 250*dt end
  if love.keyboard.isDown("down") then ty = ty - 250*dt end
  if love.keyboard.isDown("left") then tx = tx + 250*dt end
  if love.keyboard.isDown("right") then tx = tx - 250*dt end

Here we listen for a keypress and then adjust the translate variables, tx and ty appropriately.

More information can be found on Kadoba's original post here. More advanced samples are included with the loader itself.
