Simple TMX Library documentation¶

This library reads and writes the Tiled TMX format in a simple way. This is useful for map editors or generic level editors, and it’s also useful for using a map editor or generic level editor like Tiled to edit your game’s levels.

To load a TMX file, use tmx.TileMap.load(). You can then read the attributes of the returned tmx.TileMap object, modify the attributes to your liking, and save your changes with tmx.TileMap.save(). That’s it! Simple, isn’t it?

At the request of the developer of Tiled, this documentation does not explain in detail what each attribute means. For that, please see the TMX format specification, found here:

http://doc.mapeditor.org/reference/tmx-map-format/

tmx.TileMap¶

class tmx.TileMap¶

This class loads, stores, and saves TMX files.

version¶: The TMX format version.

orientation¶: Map orientation. Can be “orthogonal”, “isometric”, “staggered”, or “hexagonal”.

renderorder¶: The order in which tiles are rendered. Can be "right-down", "right-up", "left-down", or "left-up". Default is "right-down".

width¶: The width of the map in tiles.

height¶: The height of the map in tiles.

tilewidth¶: The width of a tile.

tileheight¶: The height of a tile.

staggeraxis¶: Determines which axis is staggered. Can be “x” or “y”. Set to None to not set it. Only meaningful for staggered and hexagonal maps.

staggerindex¶: Determines what indexes along the staggered axis are shifted. Can be “even” or “odd”. Set to None to not set it. Only meaningful for staggered and hexagonal maps.

hexsidelength¶: Side length of the hexagon in hexagonal tiles. Set to None to not set it. Only meaningful for hexagonal maps.

backgroundcolor¶: A Color object indicating the background color of the map, or None if no background color is defined.

nextobjectid¶: The next available ID for new objects. Set to None to not set it.

properties¶: A list of Property objects indicating the map’s properties.

tilesets¶: A list of Tileset objects indicating the map’s tilesets.

layers¶: A list of Layer, ObjectGroup, and ImageLayer objects indicating the map’s tile layers, object groups, and image layers, respectively. Those that appear in this list first are rendered first (i.e. furthest in the back).

classmethod TileMap.load(fname)¶: Load the TMX file with the indicated name and return a TileMap object representing it.

TileMap.save(fname, data_encoding='base64', data_compression=True)¶

Save the object to the file with the indicated name.

Arguments:

data_encoding – The encoding to use for layers. Can be "base64" or "csv". Set to None for the default encoding (currently "base64").
data_compression – Whether or not compression should be used on layers if possible (currently only possible for base64-encoded data).

Encode a list of integers and return the encoded data.

This is a low-level function used internally by this library; you don’t typically need to use it.
