I"m parsing the tmx file directly as a XML file, and I was wondering if there is any way to know which tileset the tile is using? I see that If i’m using two tilesets it just puts as an attribute the “gid”, so there is no way I can guess which tileset is using

Hey @Elvis_L, welcome to the forums!

This part is covered by the [following section in the manual](http://doc.mapeditor.org/en/stable/reference/tmx-map-format/#data):

> Whatever format you choose for your layer data, you will always end up with so called “global tile IDs” (gids). They are global, since they may refer to a tile from any of the tilesets used by the map. In order to find out from which tileset the tile is you need to find the tileset with the highest `firstgid` that is still lower or equal than the gid. The tilesets are always stored with increasing `firstgid`s.

You can scroll further down for a small code example of how this could be done. A linear search over the tilesets as done there will generally work out fine since most maps refer to only a few tilesets. Of course, you could also prepare an array or map to potentially make the lookup faster.

Thank you very much! I was wondering if it was something like that, since the gid that a second tileset I was using was bigger than the higher gid I was getting from the first tileset, but I wanted to be sure, thank you very much!
