Controls

This section describes the controls of Gaia Sky.

Keyboard controls

To check the most up-to-date controls go to the Controls tab in the preferences window. Here are the default keyboard controls depending on the current camera mode. Learn more about camera modes in the Camera modes section.

Keyboard mappings

The keyboard mappings are stored in an internal file called keyboard.mappings (link). If you want to edit the keyboard mappings, copy the file it into $GS_CONFIG/mappings/ (if it is not yet there) and edit it. This overrides the default internal mappings file. The file consists of a series of <ACTION>=<KEYS> entries. For example:

# Help
action.help                                 = F1
action.help                                 = H

# Exit
action.exit                                 = ESC

# Home
action.home                                 = HOME

# Preferences
action.preferences                          = P

#action.playcamera                          = C

The available actions are the following:

• action.exit – Exit application

• action.preferences – Show preferences

• action.loadcatalog – Load catalogue

Gamepad controls

Since 2.3.0

Gaia Sky supports Game controllers through SDL. This means that most controllers should just work out-of-the-box. The default controller mappings file, SDL_Controller.controller, should always be used initially. Should this file not work for your controller, you can create your custom mappings easily and interactively by going to the preferences window > controls and clicking on the “Configure” button next to your controller. Then, follow screen instructions.

Configuring gamepad controls in Gaia Sky

User mappings files (see here) can be added manually to $GS_CONFIG/mappings (see folders) folder, or set up automatically from within Gaia Sky. The controller mappings file contains the axis or button numbers for each input type. Below is an example of one such file.

#Controller mappings definition file for Wireless Steam Controller
axis.dpad.h=-1
axis.dpad.v=1
axis.lstick.h=0
axis.lstick.h.sensitivity=1.0
axis.lstick.v=1
axis.lstick.v.sensitivity=1.0
axis.lt=-1
axis.lt.sensitivity=1.0
axis.rstick.h=2

Gamepad UI

The gamepad UI allows access to some basic actions and settings directly using a gamepad. To open it, press .

The gamepad UI

There are seven tabs at the top that can be navigated with and . The tabs are the following:

• Search – provides a virtual keyboard to search for objects.

• Camera – camera parameters like the mode or the field of view.

• Time – controls to start and stop time, as well as to set the time warp factor.

• Types – visibility of elements in Gaia Sky.

• Controls – gamepad settings and mappings.

• Graphics – graphics options like post-processing effect parameters.

• System – system-wide settings. Also a button to quit Gaia Sky.

Close the gamepad UI with .

Since 3.3.1
