Returns the value associated with the specified key from the story metadata store or, if no such key exists, the specified default value, if any. SugarCube requires authors to define and work with these data types using the standard JavaScript methods rather than providing macros for them. Note: Doing so allows interactions with the text to also trigger its <>. While there are no custom properties, the event is fired from the dialog's body, thus the target property will refer to its body elementi.e., #ui-dialog-body. Note: Returns a reference to the current AudioTrack instance for chaining. This macro is functionally identical to <>, save that it also encodes HTML special characters in the output. Identical to calling .map().flat(). Temporary variables do not become part of the story history and only exist for the lifetime of the moment/turn that they're created in. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. If you wish to use custom backgrounds, either simply colors or with images, then you should place them on the body element. This property is automatically set based on whether you're using a testing mode in a Twine compileri.e., Test mode in Twine2, Test Play From Here in Twine1, or the test mode option (-t, --test) in Tweego. To resolve instances where you do, however, you'll want to use either a temporary variable or a backquote expression. Ideally, if you need to update UI bar content outside of the normal passage navigation update, then you should update only the specific areas you need to rather than the entire UI bar. classes), Updating to any version 2.30.0 from a lesser version, Updating to any version 2.29.0 from a lesser version, Updating to any version 2.28.0 from a lesser version, Updating to any version 2.20.0 from a lesser version, Updating to any version 2.15.0 from a lesser version, Updating to any version 2.10.0 from a lesser version, Updating to any version 2.8.0 from a lesser version, Updating to any version 2.5.0 from a lesser version, Updating to any version 2.0.0 from a lesser version, embedded image passage (Twine1 & Tweego only), https://cdn.jsdelivr.net/gh/tmedwards/sugarcube-2/dist/format.js. Global event triggered as the first step in closing the dialog when Dialog.close() is called. This is only really useful within pure JavaScript code, as within TwineScript you may simply access story variables natively. If no cases match and an optional <> case exists, which must be the final case, then its contents will be executed. Gets or sets the track's repeating playback state (default: false). Stops playback of the selected tracks and forces them to drop any existing data. Testing is strongly advised. Returns the save object from the autosave or null, if there was no autosave. Note: Deletes the audio group with the given group ID. Extract the archive to a safe location on your computer and make note of the path to it. If you click the link that sets the variable to 2, and then save the story, the $var variable will still be saved as 1, because a new moment has not yet been created. Skips ahead to the next track in the playlist, if any. Gets or sets the track's volume mute state (default: false). The verbatim HTML markup disables processing of all markup contained withinboth SugarCube and HTMLpassing its contents directly into the output as HTML markup for the browser. Returns a reference to the current AudioRunner instance for chaining. Used within <> macros. Harlowe's implementation of the (goto:) macro terminates the rendering passage. SugarCube Snowman Arrays Arrays Chapbook Harlowe SugarCube Snowman Audio Audio Chapbook Harlowe SugarCube Snowman Conditional Statements . If you have a property that uses an array of values, you will be able to use the various "tag" functions to . Moves forward one moment within the full history (past + future), if possible, activating and showing the moment moved to. Randomly removes the given number of members from the base array and returns the removed members as a new array. See Guide: Media Passages for more information. Local event triggered on the typing wrapper when the typing of a section starts. Warning: Strings in TwineScript/JavaScript are Unicode, however, due to historic reasons they are comprised of, and indexed by, individual UTF-16 code units rather than code points. The (execution) context object of the macro's parent, or null if the macro has no parent. Deprecated: As an example, the default replacement strings make use of this to handle various warning intros and outros. Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. The default cursor is the block element character Right Half Block (U+2590) and it has no default font or color styling. The Config.debug setting for more information. You can set the autosave to save either on every passage or only on certain passages. Warning: The exactly equivalent call is: .flat(Infinity). See the <> macro for its replacement. There's no way for the system to know ahead of time whether it's safe to re-execute a passage's contents. You will, very likely, never need to use State.current directly within your code. See: Used to replace SugarCube's default UI. See the State.prng.init() method for its replacement. Additionally, it is strongly recommended that you do not specify any arguments to State.prng.init() and allow it to automatically seed itself. If you need to check for multiple passages, the hasVisited() story function will likely be more convenient to use. This is only really useful when you want to invoke a macro for its side-effects and aren't interested in its output. The loading process is as described in SimpleAudio.load(). This method has been deprecated and should no longer be used. Prepares the dialog for use and returns a reference to its content area. Repeatedly executes its contents after the given delay, inserting any output into the passage in its place. For example, if the passage name was Gone fishin', then: For example, if the tag name was Sector_42, then it would become both the data-tags attribute member Sector_42 (selector: [data-tags~="Sector_42"]) and the class sector-42 (selector: .sector-42). Data stored there won't take up space in the game history, but will be accessible both from Twine and . For the template that should be used as the basis of localizations, see the locale/l10n-template.js file @github.com. The very first, and mandatory, character is their sigil, which denotes whether they are a story or temporary variable. Used to populate the story's menu items in the UI bar (element ID: menu-story). active) and outgoing passages. To add watches for all current variables, click the button. For game-oriented projects, as opposed to more story-oriented interactive fiction, a setting of 1 is strongly recommended. When a new moment is created, SugarCube stores the playthrough state to session storage. Config.saves.autosave setting, Config.saves.autoload setting, and Save API: Autosave. Prior to SugarCube v2.10.0, the strings localization object was named strings. This only affects test mode. Returns the size of the story metadata storei.e., the number of stored pairs. Returns an AudioRunner instance for the tracks matching the given selector. Deletes all currently registered on-load handlers. Determines whether the <> macro types out content on previously visited passages or simply outputs it immediately. Added to the active passage's container element, Added to the active passage's container element and. The core audio subsystem and backend for the audio macros. Return the named template definition, or null on failure. If you plan on using interactive macros within a loop you will likely need to use the. Once unloaded, playback cannot occur until the track's data is loaded again. Sets the selected tracks' repeating playback state (default: false). This means, however, that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. Returns whether enough data has been loaded to play the track through to the end without interruption. The previous state is completely lostthe new state is not added to or combined with the current state, instead it replaces it in its entirety. June 2017 in Help! Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. There are also "tags", which are basically arrays of values on a property of a bag or item. A right angle bracket (>) that begins a line defines the blockquote markup. If you want to change the font or color, then you'll need to change the styling of the macro-type class. Warning: This series is intended for. Use the Edit Story Stylesheet story editor menu item for styles. Instead, use the metadata property. Object Name: SugarCube.State.active.variables [How to find variables and manipulate them for people who don't know how to] Type the object name 'SugarCube.State.active.variable' into the console and press enter. If you simply want to apply actions to multiple tracks simultaneously, then you want a group instead. Meaning that when you pass a variable as an argument, its value is passed to the macro rather than its name. The API automatically calls this method at startup, so you should never need to call this method manually. See the Dialog API docs for more information. Creates a link that undoes past moments within the story history. See the .includes() method for its replacement. May be called either with a list of passages, with a list of link markup, or with a list of image markup. We have tried to point out which they do work with, but beware! By default, it uses Math.random() as its source of (non-deterministic) randomness, however, when the seedable PRNG has been enabled, via State.prng.init(), it uses that (deterministic) seeded PRNG instead. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). Returns a reference to the UIBar object for chaining. The Config API serves the same basic purpose. Activates the moment at the given index within the full state history and show it. May be terminated by a <> macro. Making custom non-generic object types fully compatible requires that two methods be added to their prototype, .clone() and .toJSON(), to support cloningi.e., deep copyinginstances of the type. The player will not be prompted and all unsaved state will be lost. As it is highly unlikely that either an array of passage names or default text will be needed in the vast majority of cases, only a few basic examples will be given. If omitted, the story title will be used instead. All these instructions are based on the SugarCube story format. Removes and returns the first member from the array, or undefined if the array is empty. Because of the additional HTML elements added by the debug views, some nested markup and selectors may be broken. This macro has been deprecated and should no longer be used. The History API object has been renamed to State and some of its methods have also changed. In SugarCube, you instead open and close the <> macro itself: Some macros in Harlowe and SugarCube share a name but work a bit differently. The Config.audio.pauseOnFadeToZero setting (default: true) controls whether tracks that have been faded to 0 volume (silent) are automatically paused. Warning: Config object settings should be placed within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage). Story variables are a part of the story history and exist for the lifetime of a playthrough session. Does not modify the original. The DOM ID of the passage, created from the slugified passage title. Track event triggered when a fade completes normally. Happens at the end of passage navigation. Returns the processed text of the passage, created from applying nobr tag and image passage processing to its raw text. Wikifies the given content source(s) and discards the result. See the :passagestart event for its replacement. When a saved story is loaded, the state loaded from the save replaces the current state. Silently executes its contents as pure JavaScript codei.e., it performs no story or temporary variable substitution or TwineScript operator processing. Returns a reference to the current temporary variables store (equivalent to: State.temporary). Each event is represented by an object that has properties that may be used to get additional information about what happened. Global event triggered once just before the page is reloaded when Engine.restart() is called. Combining the <<set> and <<if> macros. Note: Happens before the rendering of the incoming passage. Pauses playback of the track and, if it's not already in the process of loading, forces it to drop any existing data and begin loading. Sets the story's subtitle in the UI bar (element ID: story-subtitle). private browsing modes do interfere with this. This allows you to fine tune for those cases. Starts playback of the playlist and fades the currently playing track from the specified volume level to 0 (silent) over the specified number of seconds. When you have a situation where you're using a set of passages as some kind of menu/inventory/etc and it's possible for the player to interact with several of those passages, or even simply the same one multiple times, then returning them to the passage they were at before entering the menu can be problematic as they're possibly several passages removed from that originating passagethus, the <> macro and link constructs like [[Return|previous()]] will not work. Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. This guide will detail how these features work. This is chiefly intended for use by add-ons/libraries. Executes its contents while the given conditional expression evaluates to true. Terminates the execution of the current iteration of the current <> and begins execution of the next iteration. Returns whether the engine is rendering the incoming passage. To affect multiple tracks and/or groups at once, see the SimpleAudio.select() method. In SugarCube, you would instead simply prefix the selectors of your styles with the appropriate tag-based selectorse.g., either [data-tags~=""] attribute selectors or class selectors. Returns the number of moments within the full in-play history (past + future). SugarCube features a configurable autosave system. Note: Note: Loading is done asynchronously at run time, so if the stylesheet must be available within a tight time frame, then you should use the Promise returned by the function to ensure that the stylesheet is loaded before it is needed. Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importScripts(). In SugarCube, they come in two types: story variables and temporary variables. Playlists are useful for playing tracks in a sequencei.e., one after another. Returns whether playback of the track has been paused. Note: Causes leading/trailing newlines to be removed and all remaining sequences of newlines to be replaced with single spaces before the passage is rendered. Note: Happens before the modification of the state history. If no conditional expression is given, it is equivalent to specifying true. Roughly equivalent to the :passagerender event. Warning: Provides access to browsers' fullscreen functionality. For example, you may use the following JavaScript code to record the last non-menu passage into the $return story variable: (Twine2: the Story JavaScript, Twine1/Twee: a script-tagged passage). SugarCube is a free (gratis and libre) story format for Twine/Twee. Warning: This does not alter the volume level. See State API for more information. It can be loaded manually by the player or automatically by the autoload feature, which can be configured to, upon start up, either load the autosave automatically or prompt the player about loading it. All properties of Passage objects should be treated as if they were read-only, as modifying them could result in unexpected behavior. The StoryInit special passage is normally the best place to set up tracks. This means that non-widget uses of these special variable are completely safe, though this does have the effect that uses external to widgets are inaccessible within them unless passed in as arguments. Note: Closes the dialog. This method has been deprecated and should no longer be used. The links go to the most recent release versions of each in SugarCube's source code repository. The audio subsystem is based upon the HTML Media Elements APIs and comes with some built-in limitations: Pauses playback of all currently registered tracks and, if they're not already in the process of loading, force them to drop any existing data and begin loading. In practice, you'll probably want to use either line continuations or one of the no-break methods: Config.passages.nobr setting, nobr special tag, <> macro. Note: Unsupported object types, either native or custom, will need to implement .clone() method to be properly supported by the clone() functionwhen called on such an object, it will simply defer to the local method; see the Non-generic object types (a.k.a. Returns the number clamped to the specified bounds. They are defined via the Template API. Deprecated: There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. Starts playback of the playlist and fades the currently playing track from the specified volume level to 1 (loudest) over the specified number of seconds. Returns a new array consisting of the flattened source array. Note: Returns how much remains of the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. Determines whether rendering passages have their leading/trailing newlines removed and all remaining sequences of newlines replaced with single spaces before they're rendered. predisplay tasks have been deprecated and should no longer be used. Passage names have passage- prepended to their converted forms and are converted both into IDs and classes depending on how the passage is usedan ID for the active passage, classes for included (via <>) passages. As a basic working definition, non-generic object typesa.k.a. Arrays in Sugarcube have a built-in function that lets you delete elements from them by name. See Also: Performs any required processing before the save data is loadede.g., upgrading out-of-date save data. Returns a reference to the Dialog object for chaining. Request that the browser exit fullscreen mode. See Fullscreen API for more information. Warning: Deprecated: The story's title is part of the story project. Global event triggered when all <> macros within a passage have completed. Several UI API methods have moved to the new Dialog API. Starts playback of the track and fades it from the specified volume level to 0 (silent) over the specified number of seconds. Returns a pseudo-random decimal number (floating-point) within the range of the given bounds (inclusive for the minimum, exclusive for the maximum)i.e., [min,max). Begins playback of the selected tracks or, failing that, sets the tracks to begin playback as soon as the player has interacted with the document. If using an integer delay, ideally, it should probably be slightly longer than the outgoing transition delay that you intend to usee.g., an additional 10ms or so should be sufficient. Returns a reference to the current AudioRunner instance for chaining. Additionally, see the tagged stylesheet warning. Sets the maximum number of available save slots. See Template API for more information. An array is a container that holds things. May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. An array of discrete arguments parsed from the argument string. Intended to allow authors to easily wrap their custom object types (a.k.a. Note: Audio runners are useful for performing actions on multiple tracks at once. Note: Note: Iterates through all enumerable entries of the given collection. For example, a common use of <> is to perform various actions before forwarding the player to another passage. Removes event handlers from the selected tracks. Returns whether the history navigation was successful (should only fail if already at the beginning of the full history). For normal projects, authors are encouraged to continue to use the StoryInit special named passage. If its return value is falsy, the override is cancelled and navigation to the original destination continues unperturbed. For example: If you run the above, you'll see $x is 0. Generates no output. Note: Executes its contents and replaces the contents of the selected element(s) with the output. Appends the given content to the dialog's content area. Returns whether fullscreen mode is currently active. Returns the whole (integer) part of the given number by removing its fractional part, if any. Returns a random member from the base array. Gets or sets the mute state for the master volume (default: false). The body of the page. Global event triggered as the last step in closing the dialog when Dialog.close() is called. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. sugarcube-2: macros: customMacroName: container: true anotherOne: {} If using *.twee-config . Saving the story records the story's state up until the last moment that was created. Events are messages that are sent (a.k.a. A Twine 2 proofing format that renders nodes as a GraphViz (dot) graph. Temporary variables were added in v2.3.0. SugarCube includes polyfills for virtually all JavaScript (ECMAScript) 5 & 6 native object methodsvia the es5-shim and es6-shim polyfill libraries (shims only, no shams)so they may be safely used even if your project will be played in ancient browsers that do not natively support them. However, this means that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. To actually affect multiple tracks and/or groups, see the SimpleAudio.select() method. Registers the passage as <> macro definitions, which are loaded during startup. Note: SugarCube does not support the Twine1.4+ vanilla story formats' tagged stylesheets. The argument string after converting all TwineScript syntax elements into their native JavaScript counterparts. Yes it is possible. Config.macros.typeSkipKey, Config.macros.typeVisitedPassages, <> Events. State.current is not a synonym for State.active. In versions of SugarCube v2.23.0, the debugging interface offers additional tools, namely variable watches and arbitrary history navigation. Removes all of the members at the given indices from the array and returns a new array containing the removed members.
