  I don't know the code you are referring to but tileset looks like an offset to me (so integer).
  
  The if statement is checking that it is not nil, if not it is assigning whatever is in the table at that location to tilemap.

  Just to add a bit to @ChrisF answer, tileset could also be a string since lua accept both value types as table index.
  
  @chuz0 Post a link to the lua file or a "larger" piece of code

  Hi @pie and @ChrisF, sorry I just posted a bit of code assuming it was well known.
  here : http://giderosmobile.com/forum/discussion/699/using-tiled/p1
  is the thread where @atilim posted an example with tilemapmultiple class.
  Thanks for the clarifications, although I don't fully understand it...
  Once stored it in a table with a string/object index, how can I iterate through the items to find what I'm looking for ?

  @chuz0 I played a bit with tilemaps but always took the part of code in your question as a dogma...
  I may be wrong, but I think it's just using the lua address of the current tileset (as returned by gid2tileset) as an index for tilemaps table.
  
  To iterate through a table you can use pairs and ipairs, however from the main topic I assume you need to iterate through a TileMap instance to get/set tiles/objects/enemies.
  
  Maybe there are better ways to do that, but nobody shared them so you have only my examples to check :P
  Basically I save references to anything I need to access later (you lose control over local objects outside the scope in which they're created).
  
  This is some way to get/setTile on a certain layer

  This is to set properties/place enemies/objects in tiled and retrieve them in your game

  Hope this helps

  Thanks @pie, I was checking those threads too. It's that I didn't understand the indexing bit. I'll take a look on pairs and ipairs.
