Preference variables store the values of Ren'Py preferences. While the value
of a preference should be set at runtime using the Preference()
action,
preference variables should be used in conjunction with the default statement
to set the default value of a preference.
For example:
default preferences.text_cps = 40
sets the default text speed to 40 characters per second. The default statement only sets the value of the preference if the default has changed since the preference was set. For example, if the player changes the speed to 50, it will remain at 50 over future runs of the game. If, in an upgrade, the default is set to 42, the player's setting will be changed to 42. (The player can then change it again.)
preferences.afm_after_click
= False linkIf True, the auto-forward mode will be continued after a click. If False, a click will end auto-forward mode. The equivalent of the "auto-forward after click" preference.
preferences.afm_enable
= False linkIf True, auto-forward move is enabled, otherwise False. The equivalent of the "auto-forward time" preference.
preferences.afm_time
= 15 linkThe amount of time to wait for auto-forward mode. Bigger numbers are slower, though the conversion to wall time is complicated, as the speed takes into account line length. The equivalent of the "auto-forward" preference.
preferences.desktop_rollback_side
= "disable" linkWhen on a desktop platform, touches or clicks to this side of the window cause rollback to occur. One of "left", "right", or "disable". This is the equivalend of the "rollback side" preference when on a desktop platform.
preferences.mobile_rollback_side
= "disable" linkWhen on a mobile platform, touches or clicks to this side of the window cause rollback to occur. One of "left", "right", or "disable". This is the equivalend of the "rollback side" preference when on a mobile platform.
preferences.language
= None linkThe language that the player has selected to use when running the game. This is None for the default language or a string containing a language the game is translated to.
This can be used to set the default language, and can be read to determine
the current language. The Language()
action can be used to change
the language.
preferences.emphasize_audio
= False linkIf True, Ren'Py will emphasize the audio channels found in config.emphasize_audio_channels
by reducing the volume of other channels. (For example, reducing the music volume when voice
is playing.) If False, this doesn't happen.
preferences.fullscreen
= False linkThis is True when Ren'Py is in fullscreen mode, and False when it is running in a window. The equivalent of the "display" preference.
preferences.gl_framerate
= None linkThis is either an integer, or None. If not None, it's a target framerate that Ren'Py will attempt to achieve. If this is set low (for example, to 30), on a monitor with a high framerate (say, 60 frames per second), Ren'Py will only draw on every other frame.
If None, Ren'Py will attempt to draw at the monitor's full framerate.
preferences.gl_powersave
= "auto" linkThis determines how often Ren'Py will redraw an unchanging screen. If True, Ren'Py will only draw the screen 5 times a second. If False, it will always draw at the full framerate possible. If "auto", it will draw at full speed when the device is powered, and 5hz when it is running on battery.
preferences.gl_tearing
= False linkThis determines if tearing (True) or frameskip (False) is the preferred behavior when the game can't keep up with its intended framerate.
preferences.mouse_move
= True linkIf True, the mouse will automatically move to a selected button. If False, it will not. The equivalent of the "automatic mouse move" preference.
preferences.show_empty_window
= True linkIf True, the window show and window auto statements will function. If False, those statements are disabled. The equivalent of the "show empty window" preference.
preferences.skip_after_choices
= False linkIf True, skipping will resume after a choice. If False, a choice will prevent Ren'Py from skipping. The equivalent of the "after choices" preference.
preferences.skip_unseen
= False linkWhen True, Ren'Py will skip all text. When False, Ren'Py will only skip text that has been read by the player in any session. The equivalent of the "skip" preference.
preferences.text_cps
= 0 linkThe speed of text display. 0 is infinite, otherwise this is the number of characters per second to show. The equivalent of the "text speed" preference.
preferences.transitions
= 2 linkDetermines which transitions should be shown. 2 shows all transitions, 0 shows no transitions. (1 is reserved.) The equivalent of the "transitions" preference.
preferences.video_image_fallback
= False linkIf True, images are displayed instead of videosprites. If False, video sprites are displayed normally. The equivalent (inverted) of the "video sprites" preference.
preferences.voice_sustain
= False linkIf True, voice keeps playing until finished, or another voice line replaces it. If False, the voice line ends when the line of dialogue advances. The equivalent of the "voice sustain" preference.
preferences.wait_voice
= True linkIf True, auto-forward mode will wait for voice files and self-voicing to finish before advancing. If False, it will not. The equivalent of the "wait for voice" preference.
preferences.system_cursor
= False linkIf True, the system cursor is forced to be used, ignoring the
config.mouse
value. If False, it will not. The equivalent of the
"system cursor" preference.
preferences.audio_when_minimized
= True linkIf False, audio channels are stopped when the window is minimized, and resumed when the window is restored. If True, window state will have no effect on audio. The equivalent of the "audio when minimized" preference.

get_volume
(mixer) linkGets the volume for mixer. If the mixer is muted, this returns 0.0.

set_mute
(mixer, mute) linkSets the mute setting for mixer. If mute is true, the mixer is muted. If mute is false, the mixer's volume is reverted to its value before it was muted.

get_mute
(mixer) linkGets the mute setting for mixer.
These config variables set the default volumes on various audio mixers.
config.default_music_volume
= 1.0 linkThe default volume of the music mixer, which is used for the music and movie channels. This should be a number between 0.0 and 1.0, with 1.0 being full volume.
config.default_sfx_volume
= 1.0 linkThe default volume of the sfx mixer, which is used for the sound and audio channels. This should be a number between 0.0 and 1.0, with 1.0 being full volume.
config.default_voice_volume
= 1.0 linkThe default volume of the voice mixer, which is used for the voice channel (and hence the voice statement, auto-voice, etc.). This should be a number between 0.0 and 1.0, with 1.0 being full volume.
