Screen Actions, Values, and Functions link

Ren'Py ships with a number of actions, values, and functions intended for use with screens and the screen language.

Actions link

Actions are invoked when a button (including imagebuttons, textbuttons, and hotspots) is activated, hovered, or unhovered. Actions may determine when a button is selected or insensitive.

Along with these actions, an action may be a function that does not take any arguments. The function is called when the action is invoked. If the action returns a value, then the value is returned from an interaction.

A list of actions can usually be provided in lieu of a single action, in which case the actions in the list are run in order. A list of actions is sensitive if all of the actions are sensitive, and selected if any of them are ; that unless SensitiveIf() or SelectedIf(), respectively, is part of the list.

Control Actions link

These are actions that manage screens, interaction results, and control flow.

Call(label, *args, **kwargs) link: Ends the current statement, and calls label, given as a string. Arguments and keyword arguments are passed to renpy.call().

Hide(screen=None, transition=None, _layer=None, immediately=False) link

This causes a screen to be hidden if it is shown.

screen: Either a string giving the name of the screen to be hidden, or None to hide the current screen.
transition: If not None, a transition that occurs when hiding the screen.
_layer: This is passed as the layer argument to renpy.hide_screen(). Ignored if screen is None.
immediately: If True, the screen is hidden immediately, without the 'on hide' event.

Jump(label) link: Causes control to transfer to label, given as a string.

NullAction() link

Does nothing.

This can be used to make a button responsive to hover/unhover events, without actually doing anything.

Return(value=None) link

Causes the current interaction to return the supplied non-None value. This is often used with menus and imagemaps, to select what the return value of the interaction is. If the screen was called using the call screen statement, the return value is placed in the _return variable.

When in a menu, this returns from the menu. (The value should be None in this case.)

Show(screen, transition=None, *args, **kwargs) link

This causes another screen to be shown. screen is a string giving the name of the screen. The arguments are passed to the screen being shown.

If not None, transition is used to show the new screen.

This action takes the _layer, _zorder and _tag keyword arguments, which have the same meaning as in the renpy.show_screen() function.

ShowTransient(screen, transition=None, *args, **kwargs) link

Shows a transient screen. A transient screen will be hidden when the current interaction completes. The arguments are passed to the screen being shown.

If not None, transition is use to show the new screen.

This action takes the _layer, _zorder and _tag keyword arguments, which have the same meaning as in the renpy.show_screen() function.

ToggleScreen(screen, transition=None, *args, **kwargs) link

This toggles the visibility of screen. If it is not currently shown, the screen is shown with the provided arguments. Otherwise, the screen is hidden.

If not None, transition is use to show and hide the screen.

This action takes the _layer, _zorder and _tag keyword arguments, which have the same meaning as in the renpy.show_screen() function.

Data Actions link

A number of these actions, encompassing the most usual cases, follow a simple pattern shown in the following table:

Managers	Accessors
Managers	Variable	ScreenVariable	LocalVariable	Field	Dict
Set	`SetVariable()`	`SetScreenVariable()`	`SetLocalVariable()`	`SetField()`	`SetDict()`
Toggle	`ToggleVariable()`	`ToggleScreenVariable()`	`ToggleLocalVariable()`	`ToggleField()`	`ToggleDict()`
Cycle	`CycleVariable()`	`CycleScreenVariable()`	`CycleLocalVariable()`	`CycleField()`	`CycleDict()`
Increment	`IncrementVariable()`	`IncrementScreenVariable()`	`IncrementLocalVariable()`	`IncrementField()`	`IncrementDict()`

The accessors determine the target whose value will change, and the manager determines what the new value will be. Their behavior is relatively simple to grasp:

The -Variable actions change the value of the global variable called name, found in the general store. The name argument must be a string, and can be a simple name like "strength", or one with dots separating the variable from fields, like "hero.strength" or "persistent.show_cutscenes".
The -ScreenVariable actions change the value of the variable called name, associated with the current top-level screen. In a used screen, this action sets the variable in the context of the screen containing all the used one(s).
The -LocalVariable actions change the value of the variable called name, taken locally to the screen it's in. This action is only useful in a screen that has been used by another screen (for more information, see Use). In all other cases, the -ScreenVariable actions should be preferred, as yielding better performance and allowing more of the screen to be cached. The -LocalVariable actions must be created in the context that the variable is set in - it can't be passed in from somewhere else.
The -Field actions change the value of the field called field of the object object.
The -Dict actions change the value of the key key in the dictionary dict : they change dict[key]. This also works with lists.

The Set- actions simply set the value of the target to the passed value. Note that this has nothing to do with set, which is a builtin type in Python. target = value
The Toggle- actions invert the boolean value of their target, between true_value (if given and not None) and false_value (same). When true_value and false_value are both None, target = not target
The Cycle- actions cycle through the provided values, which must be a non-empty sequence (a list, tuple or range). If the target's value is not in the sequence at the time the action runs, it is set to the first value in the sequence. The loop parameter (defaulting to True) determines what happens when the values run out : if True it's started from the beginning, if False it raises an exception. The reverse parameter (defaulting to False) reverses the passed values sequence.
The Increment- actions add amount to their target, which defaults to 1 but may be of any type compatible with the target. target = target + amount

The following data actions do not follow the pattern above. Some of them are related to Python's set type, not to be confused with the Set- actions above.

AddToSet(set, value) link

Adds value to set.

set: The set to add to. This may be a Python set or list, in which case the value is appended to the list.
value: The value to add or append.

RemoveFromSet(set, value) link

Removes value from set.

set: The set to remove from. This may be a set or list.
value: The value to remove.

ToggleSetMembership(set, value) link

Toggles the membership of value in set. If the value is not in the set, it's added. Otherwise, it is removed.

Buttons with this action are marked as selected if and only if the value is in the set.

set: The set to add to or remove from. This may be a set or list. In the case of a list, new items are appended.
value: The value to add or append.

Menu Actions link

These actions invoke menus, or are primarily useful while in the main or game menus.

Continue(regexp='[^_]', confirm=True) link

Causes the last save to be loaded. The purpose of this is to load the player's last save from the main menu.

regexp: If present, will be used in renpy.newest_slot. The default pattern will continue from any save, including quick saves and auto saves. If you want to continue from only saves created by the player, set this to r"\d".
confirm: If true, causes Ren'Py to ask the user if they want to continue where they left off, if they are not at the main menu.

MainMenu(confirm=True, save=True) link

Causes Ren'Py to return to the main menu.

confirm: If true, causes Ren'Py to ask the user if he wishes to return to the main menu, rather than returning directly.
save: If true, the game is saved in _quit_slot before Ren'Py restarts and returns the user to the main menu. The game is not saved if _quit_slot is None.

Quit(confirm=None) link

Quits the game.

confirm: If true, prompts the user if he wants to quit, rather than quitting directly. If None, asks if and only if the user is not at the main menu.

ShowMenu(screen=_game_menu_screen, *args, _transition=config.intra_transition, **kwargs) link

Causes us to enter the game menu, if we're not there already. If we are in the game menu, then this shows a screen or jumps to a label.

screen is usually the name of a screen, which is shown using the screen mechanism. If the screen doesn't exist, then "_screen" is appended to it, and that label is jumped to. the screen mechanism with the *args and **kwargs passed to the screen. If the screen doesn't exist, then "_screen" is appended to it, and that label is jumped to, ignoring args and kwargs.

If the optional keyword argument _transition is given, the menu will change screens using the provided transition. If not manually specified, the default transition is config.intra_transition.

ShowMenu("load")
ShowMenu("save")
ShowMenu("preferences")

This can also be used to show user-defined menu screens. For example, if one has a "stats" screen defined, one can show it as part of the game menu using:

ShowMenu("stats")

ShowMenu without an argument will enter the game menu at the default screen, taken from _game_menu_screen.

Extra arguments and keyword arguments are passed on to the screen

Start(label='start') link

Causes Ren'Py to jump out of the menu context to the named label. The main use of this is to start a new game from the main menu. Common uses are:

Start() - Start at the start label.
Start("foo") - Start at the "foo" label.

File Actions link

These actions handle saving, loading, and deleting of files. Many of these take the name and page arguments.

name: The name of the file to save to. This can be a string or an integer. It's combined with the page to create the filename.
page: The page that this action acts on. This is one of "auto", "quick", or a positive integer. If None, the page is determined automatically, based on a persistent page number.

These are converted to a slot name using config.file_slotname_callback, if it's set.

FileAction(name, page=None, **kwargs) link

"Does the right thing" with the file. This means loading it if the load screen is showing (current screen is named "load"), and saving otherwise.

name: The name of the slot to save to or load from. If None, an unused slot (a large number based on the current time) will be used.
page: The page that the file will be saved to or loaded from. If None, the current page is used.

Other keyword arguments are passed to FileLoad or FileSave.

FileDelete(name, confirm=True, page=None, slot=False) link

Deletes the file.

name: The name of the slot to delete.
confirm: If true and not at the main menu, prompt for confirmation before loading the file.
page: The page that the file will be loaded from. If None, the current page is used.
slot: If True, name is taken to be a slot name, and page is ignored.

FileLoad(name, confirm=True, page=None, newest=True, cycle=False, slot=False) link

Loads the file.

name: The name of the slot to load from. If None, an unused slot will be used, and hence the file will not be loadable.
confirm: If true and not at the main menu, prompt for confirmation before loading the file.
page: The page that the file will be loaded from. If None, the current page is used.
newest: If true, the button is selected if this is the newest file.
cycle: Ignored.
slot: If True, name is taken to be a slot name, and page is ignored.

FilePage(page) link: Sets the file page to page, which should be one of "auto", "quick", or an integer.

FilePageNext(max=None, wrap=False, auto=True, quick=True) link

Goes to the next file page.

max: If set, this should be an integer that gives the number of the maximum file page we can go to.
wrap: If true, we can go to the first page when on the last file page if max is set.
auto: If true and wrap is set, this can bring the player to the page of automatic saves.
quick: If true and wrap is set, this can bring the player to the page of automatic saves.

FilePagePrevious(max=None, wrap=False, auto=True, quick=True) link

Goes to the previous file page, if possible.

max: If set, this should be an integer that gives the number of the maximum file page we can go to. This is required to enable wrap.
wrap: If true, we can go to the last page when on the first file page if max is set.
auto: If true, this can bring the player to the page of automatic saves.
quick: If true, this can bring the player to the page of automatic saves.

FileSave(name, confirm=True, newest=True, page=None, cycle=False, slot=False, action=None) link

Saves the file.

The button with this slot is selected if it's marked as the newest save file.

name: The name of the slot to save to. If None, an unused slot (a large number based on the current time) will be used.
confirm: If true, then we will prompt before overwriting a file.
newest: Ignored.
page: The name of the page that the slot is on. If None, the current page is used.
cycle: If true, then saves on the supplied page will be cycled before being shown to the user. config.quicksave_slots slots are used in the cycle.
slot: If True, name is taken to be a slot name, and page is ignored.
action: An action that is run after the save is complete. This is only run if the save is successful.

FileTakeScreenshot() link: Take a screenshot to be used when the game is saved. This can be used to ensure that the screenshot is accurate, by taking a picture of the screen before a file save screen is shown.

QuickLoad(confirm=True) link

Performs a quick load.

confirm: If true and not at the main menu, prompt for confirmation before loading the file.

QuickSave(message='Quick save complete.', newest=False) link

Performs a quick save.

message: A message to display to the user when the quick save finishes.
newest: Set to true to mark the quicksave as the newest save.

Audio Actions link

The concept of channels and how they work, as well as most information about audio in Ren'Py, is explained at Audio.

GetMixer(mixer, db=False) link

Returns the volume of mixer.

db: If true, returns the volume in decibels. If false, the default, returns the volume as a number between 0.0 and 1.0.

PauseAudio(channel, value=True) link

Sets the pause flag for channel.

If value is True, the channel is paused. If False, the channel is unpaused. If "toggle", the pause flag will be toggled.

Play(channel, file, selected=None, **kwargs) link

Causes an audio file to be played on a given channel.

channel: The channel to play the sound on.
file: The file to play.
selected: If True, buttons using this action will be marked as selected if the file is playing on the channel. If False, this action will not cause the button to start playing. If None, the button is marked selected if the channel is a music channel, and not otherwise.

Any other keyword arguments are passed to renpy.music.play().

Queue(channel, file, **kwargs) link

Causes an audio file to be queued on a given channel.

channel: The channel to play the sound on.
file: The file to play.

Any keyword arguments are passed to renpy.music.queue()

SetMixer(mixer, volume) link

Toggles the mute status of one or more mixers.

mixer: Either a single string giving a mixer name, or a list of strings giving a list of mixers. The strings should be mixer names.

Focus Actions link

CaptureFocus(name='default') link

If a displayable is focused when this action is run, the rectangle containing that displayable is stored with the name name. This rectangle can then be retrieved with the GetFocusRect() action, or the focus property of the Nearrect displayable.

If no displayable is focused, the previous capture with that name is removed.

name: The name of the focus rectangle to store. This should be a string. The name "tooltip" is special, as it is automatically captured when the tooltip is changed.

ClearFocus(name='default') link: Clears a stored focus rectangle captured with CaptureFocus(). If name is None, all focus rectangles are cleared.

GetFocusRect(name='default') link

If a focus rectangle with the given name has been stored (either with CaptureFocus(), or automatically by a tooltip, returns the a (x, y, h, w) rectangle. Otherwise, returns None.

name: The name of the focus rectangle to retrieve. The name "tooltip" is special, as it is automatically captured when the tooltip is changed.

ToggleFocus(name='default') link

If the focus rectangle exists, clears it, otherwise captures it.

name: The name of the focus rectangle to store. This should be a string. The name "tooltip" is special, as it is automatically captured when the tooltip is changed.

Bar Values link

Bar values are used with bars, to set the bar value, and to allow the bar to adjust an underlying property. To create a new bar value, subclass the BarValue class. All classes that have the step keyword also accept the force_step keyword whose behavior is described in ui.adjustment().

AnimatedValue(value=0.0, range=1.0, delay=1.0, old_value=None) link

This animates a value, taking delay seconds to vary the value from old_value to value.

value: The value itself, a number.
range: The range of the value, a number.
delay: The time it takes to animate the value, in seconds. Defaults to 1.0.
old_value: The old value. If this is None, then the value is taken from the AnimatedValue we replaced, if any. Otherwise, it is initialized to value.

AudioPositionValue(channel='music', update_interval=0.1) link

A value that shows the playback position of the audio file playing in channel.

update_interval: How often the value updates, in seconds.

dict

The dict, or the list.

key

The key, or the index when using a list.

range

The range to adjust over. This must be specified if max and min are not given.

max_is_zero

If True, then when the key or index's value is zero, the value of the bar will be range, and all other values will be shifted down by 1. This works both ways - when the bar is set to the maximum, the value of the key or index is set to 0.

This is used internally, for some preferences.

An offset to add to the value.

step

The amount to change the bar by. If None, defaults to 1/10th of the bar.

action

If not None, an action to call when the key or index's value is changed.

min

max_is_zero

If True, then when the field's value is zero, the value of the bar will be range, and all other values will be shifted down by 1. This works both ways - when the bar is set to the maximum, the value of the field is set to 0.

This is used internally, for some preferences.

style

The styles of the created bar.

offset

An offset to add to the value.

step

The amount to change the bar by. If None, defaults to 1/10th of the bar.

range

The range to adjust over. This must be specified if max and min are not given.

max_is_zero

MixerValue(mixer) link

The value of an audio mixer.

mixer: The name of the mixer to adjust. This is usually one of "main", "music", "sfx", or "voice". See Volume for more information.

ScreenVariableValue(variable, range=None, max_is_zero=False, style='bar', offset=0, step=None, action=None, force_step=False, min=None, max=None) link

The range to adjust over. This must be specified if max and min are not given.

max_is_zero

If True, then when the variable's value is zero, the value of the bar will be range, and all other values will be shifted down by 1. This works both ways - when the bar is set to the maximum, the value of the variable is set to 0.

YScrollValue(viewport) link: The value of an adjustment that vertically scrolls the viewport with the given id, on the current screen. The viewport must be defined before a bar with this value is.

Input Values link

Input values are used with text inputs, to set the default text, to accept changed text, to respond to the enter key, and to determine if the text is editable by default. To create a new input value, subclass the InputValue class.

Ren'Py-defined input values inherit from InputValue, which means that all values also include Enable(), Disable(), and Toggle() methods that return actions that enable, disable, and toggle editing, respectively. See also the DisableAllInputValues() action.

DictInputValue(dict, key, default=True, returnable=False) link

An input value that updates dict[key].

dict: May be a dict object or a list.
default: If true, this input can be editable by default.

FieldInputValue(object, field, default=True, returnable=False) link

An input value that updates field on object.

field: A string giving the name of the field.
default: If true, this input can be editable by default.
returnable: If true, the value of this input will be returned when the user presses enter.

FilePageNameInputValue(pattern='Page {}', auto='Automatic saves', quick='Quick saves', page=None, default=False) link

An input value that updates the name of a file page.

pattern: This is used for the default name of a page. Python-style substition is performed, such that {} is replaced with the number of the page.
auto: The name of the autosave page.
quick: The name of the quicksave page.
page: If given, the number of the page to display. This should usually be left as None, to give the current page.
default: If true, this input can be editable by default.

LocalVariableInputValue(variable, default=True, returnable=False) link

An input value that updates a local variable in a used screen.

To target a variable in a top-level screen, prefer using ScreenVariableInputValue().

default: If true, this input can be editable by default.
returnable: If true, the value of this input will be returned when the user presses enter.

ScreenVariableInputValue(variable, default=True, returnable=False) link

An input value that updates a variable in a screen.

In a used screen, this targets a variable in the context of the screen containing the used one(s). To target variables within a used screen, and only in that case, use LocalVariableInputValue() instead.

If true, this input can be editable by default.

returnable

If true, the value of this input will be returned when the user presses enter.

Functions and Classes link

These functions and classes are useful in association with screens.

Preferences link

While all preferences can be defined based on the Actions and Values given above, it requires some knowledge of Ren'Py to figure out the correct one to use.

GetCharacterVolume(voice_tag) link: This returns the volume associated with voice tag, a number between 0.0 and 1.0, which is interpreted as a fraction of the mixer volume for the voice channel.

Gamepad link

These functions and actions work with the gamepad.

GamepadCalibrate() link: An action that invokes the gamepad calibration routine.

GamepadExists(developer=True) link

A function that returns true if a gamepad is present, and false otherwise.

developer: Forces this function to always return true while config.developer is true.

File Functions link

These functions return useful information about files. They use the same default page as the file actions.

FileCurrentPage() link: Returns the current file page as a string.

class FileCurrentScreenshot(empty=None, **properties) link

A displayable that shows the screenshot that will be saved with the current file, if a screenshot has been taken when entering a menu or with FileTakeScreenshot().

If there is no current screenshot, empty is shown in its place. (If empty is None, it defaults to Null().)

FileJson(name, key=None, empty=None, missing=None, page=None, slot=False) link

Accesses the Json information associated with name.

This always returns empty if the slot is empty.

If not, and if key is None, returns the entire dictionary containing the Json data.

Otherwise, this returns json[key] if key is defined on the json object of the save, and missing if there is a save with the given name, but it does not contain key.

Such Json data is added to a save slot by callbacks registered using config.save_json_callbacks.

By default, the following keys are defined:

_save_name: The value of save_name when the game was saved.
_renpy_version: The version of Ren'Py the save was created with.
_version: The value of config.version when the save was created.
_game_runtime: The result of calling renpy.get_game_runtime().
_ctime: The time the save was created, in seconds since January 1, 1970, UTC.

FileLoadable(name, page=None, slot=False) link: This is a function that returns true if the file is loadable, and false otherwise.

FileNewest(name, page=None, slot=False) link: Returns True if this is the newest file slot, or False otherwise.

FilePageName(auto='a', quick='q') link: Returns the name of the current file page, as a string. If a normal page, this returns the page number. Otherwise, it returns auto or quick.

FileSaveName(name, empty='', page=None, slot=False) link: Return the save_name that was in effect when the file was saved, or empty if the file does not exist.

FileScreenshot(name, empty=None, page=None, slot=False) link

Returns the screenshot associated with the given file. If the file is not loadable, then empty is returned, unless it's None, in which case, a Null displayable is created.

The return value is a displayable.

FileSlotName(slot, slots_per_page, auto='a', quick='q', format='%s%d') link

Returns the name of the numbered slot. This assumes that slots on normal pages are numbered in a linear order starting with 1, and that page numbers start with 1. When slot is 2, and slots_per_page is 10, and the other variables are the defaults:

When the first page is showing, this returns "2".
When the second page is showing, this returns "12".
When the auto page is showing, this returns "a2".
When the quicksave page is showing, this returns "q2".

slot: The number of the slot to access.
slots_per_page: The number of slots per page.
auto: A prefix to use for the auto page.
quick: A prefix to use for the quick page.
format: The formatting code to use. This is given two arguments: A string giving the page prefix, and an integer giving the slot number.

FileTime(name, format='%b %d, %H:%M', empty='', page=None, slot=False) link

Returns the time the file was saved, formatted according to the supplied format. If the file is not found, empty is returned.

The return value is a string.

FileUsedSlots(page=None, highest_first=True) link

Returns a list of used numeric file slots on the page.

page: The name of the page that will be scanned. If None, the current page is used.
highest_first: If true, the highest-numbered file slot is listed first. Otherwise, the lowest-numbered slot is listed first.

Side Image Functions link

This function returns the side image to use.

SideImage() link: Returns the side image associated with the currently speaking character, or a Null displayable if no such side image exists.

Tooltips link

Tooltips can now be accessed by the tooltip property available on all displayables, and the GetTooltip function. The GetTooltip function returns the value of the tooltip property when the displayable gains focus.

As a reminder, values passed to the tooltip property must support equality.

Here's an example:

screen tooltip_example():
    vbox:
        textbutton "North":
            action Return("n")
            tooltip "To meet a polar bear."

        textbutton "South":
            action Return("s")
            tooltip "All the way to the tropics."

        textbutton "East":
            action Return("e")
            tooltip "So we can embrace the dawn."

        textbutton "West":
            action Return("w")
            tooltip "Where to go to see the best sunsets."

        $ tooltip = GetTooltip()

        if tooltip:
            text "[tooltip]"

The Nearrect displayable can be used to display "popup-style" tooltips, and has support for a special "tooltip" focus name, that is set to the location of the last focus that set a tooltip:

screen tooltip_example2():
    frame:

        padding (20, 20)
        align (.5, .3)

        has vbox

        textbutton "North":
            action Return("n")
            tooltip "To meet a polar bear."

        textbutton "South":
            action Return("s")
            tooltip "All the way to the tropics."

        textbutton "East":
            action Return("e")
            tooltip "So we can embrace the dawn."

        textbutton "West":
            action Return("w")
            tooltip "Where to go to see the best sunsets."

    # This has to be the last thing shown in the screen.

    $ tooltip = GetTooltip()

    if tooltip:

        nearrect:
            focus "tooltip"
            prefer_top True

            frame:
                xalign 0.5
                text tooltip

GetTooltip(screen=None, last=False) link

Returns the tooltip of the currently focused displayable, or None if no displayable is focused.

screen: If not None, this should be the name or tag of a screen. If given, this function only returns the tooltip if the focused displayable is part of the screen.
last: If true, returns the last non-None value this function would have returned.

Warning

This has been obsoleted by the above, but you might see it in older projects.

The tooltip class changes the screen when a button is hovered.

class Tooltip(default) link

A tooltip object can be used to define a portion of a screen that is updated when the mouse hovers an area.

A tooltip object has a value field, which is set to the default value passed to the constructor when the tooltip is created. When a button using an action created by the tooltip is hovered, the value field changes to the value associated with the action.

Action(value) link: Returns an action that is generally used as the hovered property of a button. When the button is hovered, the value field of this tooltip is set to value. When the button loses focus, the value field of this tooltip reverts to the default.

When using a tooltip with a screen, the usual behavior is to create a tooltip object in a default statement. The value of the tooltip and the action method can then be used within the screen. The order of use within a screen doesn't matter – it's possible to use the value before an action is used.

Tooltips can take on any value. While in the example below we use the text statement to display a string on the screen, it's also possible to use the add statement to add a displayable. More complex behavior is also possible.

screen tooltip_test:

    default tt = Tooltip("No button selected.")

    frame:
        xfill True

        has vbox

        textbutton "One.":
            action Return(1)
            hovered tt.Action("The loneliest number.")

        textbutton "Two.":
            action Return(2)
            hovered tt.Action("Is what it takes.")

        textbutton "Three.":
            action Return(3)
            hovered tt.Action("A crowd.")

        text tt.value
