# Using Commands¶

The Command Button allows you to create and run shell commands (other programs) from Tiled.

You may setup as many commands as you like. This is useful if you edit maps for multiple games and you want to set up a command for each game. Or you could setup multiple commands for the same game that load different checkpoints or configurations.

## The Command Button¶

It is located on the main toolbar to the right of the redo button. Clicking on it will run the default command (the first command in the command list). Clicking the arrow next to it will bring down a menu that allows you to run any command you have set up, as well as an option to open the Edit Commands dialog. You can also find all the commands in the File menu.

Apart from this, you can set up custom keyboard shortcuts for each command.

## Editing Commands¶

The ‘Edit Commands’ dialog contains a list of commands. Each command has several properties:

Name
The name of the command as it will be shown in the drop down list, so you can easily identify it.
Executable
The executable to run. It should either be a full path or the name of an executable in the system PATH.
Arguments
The arguments for running the executable.
Working directory
The path to the working directory.
Shortcut
A custom key sequence to trigger the command. You can use ‘Clear’ to reset the shortcut.
Output in Debug Console
If this is enabled, then the output (stdout and stderr) of this command will be displayed in the Debug Console. You can find the Debug Console in View > Views and Toolbars > Debug Console.
Save map before executing
If this is enabled, then the current map will be saved before executing the command.
Enabled
A quick way to disable commands and remove them from the drop down list. The default command is the first enabled command.

Note that if the executable or any of its arguments contain spaces, these parts need to be quoted.

### Substituted Variables¶

In the executable, arguments and working directory fields, you can use the following variables:

%mapfile
the current maps full path.
%mappath
the full folder path in which the map is located. (since Tiled 0.18)
%objecttype
the type of the currently selected object, if any. (since Tiled 0.12)
%objectid
the ID of the currently selected object, if any. (since Tiled 0.17)
%layername
the name of the currently selected layer. (since Tiled 0.17)

For the working directory field, you can additionally use the following variable:

%executablepath
the path to the executable.

## Example Commands¶

Launching a custom game called “mygame” with a -loadmap parameter and the mapfile:

mygame -loadmap %mapfile


On Mac, remember that Apps are folders, so you need to run the actual executable from within the Contents/MacOS folder:

/Applications/TextEdit.app/Contents/MacOS/TextEdit %mapfile


Or use open (and note the quotes since one of the arguments contains spaces):

open -a "/Applications/CoronaSDK/Corona Simulator.app" /Users/user/Desktop/project/main.lua


Some systems also have a command to open files in the appropriate program:

• OSX: open %mapfile
• GNOME systems like Ubuntu: gnome-open %mapfile
• FreeDesktop.org standard: xdg-open %mapfile
