Tiled ships with a plugin that enables you to use Python 3 to add support for custom map formats. This is nice especially since you don’t need to compile Tiled yourself and the scripts are easy to deploy to any platform.
For the scripts to get loaded, they should be placed in
Tiled watches this directory for changes, so there is no need to restart
Tiled after adding or changing scripts (though the directory needs to
exist when you start Tiled).
There are several example scripts available in the repository.
To create the
~/.tiled folder on Windows, open command prompt
cmd.exe), which should start in your home folder by default, then
mkdir .tiled to create the folder.
On Linux, folders starting with a dot are hidden by default. In most file
managers you can toggle showing of hidden files using
Since Tiled 1.2.4, the Python plugin is disabled by default, because depending on which Python version is installed on the system the loading of this plugin may cause a crash (#2091). To use the Python plugin, first enable it in the Preferences.
On Windows, Python is not installed by default. For the Tiled Python plugin to work, you’ll need to install Python 3.7 (get it from https://www.python.org/). You will also need to check the box “Add Python 3.7 to PATH” in the installer:
On Linux you will also need to install the appropriate package. However, currently Linux builds are done on Ubuntu 18.04 against Python 3.6, and you’d need to install the same version somehow.
The Python plugin is currently not enabled for macOS releases. We’ll need to find out how to build it against Python 3, while macOS only ships with Python 2.7 by default. If you rely on this plugin on macOS you’ll need to use Tiled 1.1 for now.
Example Export Plugin¶
Suppose you’d like to have a map exported in the following format:
29,29,29,29,29,29,32,-1,34,29,29,29,29,29,29, 29,29,29,29,29,29,32,-1,34,29,29,29,29,29,29, 29,29,29,29,29,29,32,-1,34,29,29,29,29,29,29, 29,29,29,29,29,29,32,-1,34,29,29,29,29,29,29, 25,25,25,25,25,25,44,-1,34,29,29,29,29,29,29, -1,-1,-1,-1,-1,-1,-1,-1,34,29,29,29,29,29,29, 41,41,41,41,41,41,41,41,42,29,29,24,25,25,25, 29,29,29,29,29,29,29,29,29,29,29,32,-1,-1,-1, 29,29,29,29,29,29,39,29,29,29,29,32,-1,35,41, 29,29,29,29,29,29,29,29,29,29,29,32,-1,34,29, 29,29,29,29,29,29,29,29,37,29,29,32,-1,34,29;
You can achieve this by saving the following
example.py script in
the scripts directory:
from tiled import * class Example(Plugin): @classmethod def nameFilter(cls): return "Example files (*.example)" @classmethod def shortName(cls): return "example" @classmethod def write(cls, tileMap, fileName): with open(fileName, 'w') as fileHandle: for i in range(tileMap.layerCount()): if isTileLayerAt(tileMap, i): tileLayer = tileLayerAt(tileMap, i) for y in range(tileLayer.height()): tiles =  for x in range(tileLayer.width()): if tileLayer.cellAt(x, y).tile() != None: tiles.append(str(tileLayer.cellAt(x, y).tile().id())) else: tiles.append(str(-1)) line = ','.join(tiles) if y == tileLayer.height() - 1: line += ';' else: line += ',' print(line, file=fileHandle) return True
Then you should see an “Example files” entry in the type dropdown when going to File > Export, which allows you to export the map using the above script.
This example does not support the use of group layers, and in fact the script API doesn’t support this yet either. Any help with maintaining the Python plugin would be very appreciated. See open issues related to Python support.
Debugging Your Script¶
Any errors that happen while parsing or running the script are printed to the Console, which can be enabled in View > Views and Toolbars > Console.
