To add a watch for a variable, type its name into the Add field and then either press enter/return or click the buttonn.b. Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. Creates a list of single-use passage links. To affect multiple tracks and/or groups at once, see the SimpleAudio.select() method. Combining the <<set> and <<if> macros. Adds an audio group with the given group ID. Appends one or more members to the end of the base array and returns its new length. Returns the number of passages within the story history that are tagged with all of the given tags. This feature also prevents players from losing progress if they try to use the browser back and forward buttons to navigate, or if they refresh their browser for any reason. Twine1/Twee: Registers the passage as JavaScript code, which is executed during startup. Note: Warning: Returns a reference to the current jQuery object for chaining. Deletes the audio group with the given group ID. Used for pre-story-start initialization tasks, like variable initialization (happens at the beginning of story initialization). This method will not return "code" passagesi.e., script, stylesheet, and widget passages. See Also: This method has been deprecated and should no longer be used. classes) guide for more information. . In Harlowe, the same operation will yield an error: You must convert the values to the same type in Harlowe. All widgets may access arguments passed to them via the _args special variable. 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. Executes its contents and prepends the output to the contents of the selected element(s). Pauses playback of the playlist and, if they're not already in the process of loading, forces its tracks to drop any existing data and begin loading. Note: As you can see, Harlowe creates a deep copy/clone of its non-primitive data types each time they're modified. Global event triggered as the last step in opening the dialog when Dialog.open() is called. The story history contains moments (states) created during play. The autosave is, for the most part, a normal save slot, but with a few special features built in. Widget contents string (only inside block widgets). Passage end. For example: In general, you can group expressions into categories based on what kind of value they yield and/or what side effects they cause. See Save API for more information. Warning: This setting has been deprecated and should no longer be used. Triggered before the modification of the state history. Its return value should be the post-processed text. Returns the number of milliseconds that have passed since the current passage was rendered to the page. If no autosave exists, then the starting passage is rendered. Returns the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. Deserializes the given save string, created via Save.serialize(), and loads the save. Returns the seed from the seedable PRNG or, if the PRNG is not enabled, null. Returns whether the history navigation was successful (should only fail if already at the beginning of the full history). represents whitespace that will be removed, represents line breaks). Returns the save object from the autosave or null, if there was no autosave. Note: Deprecated: See the Save.onSave.add() method for its replacement. In-browser savesi.e., autosave and slot savesare largely incompatible with private browsing modes, which cause all in-browser storage mechanisms to either persist only for the lifetime of the browsing session or fail outright. When used to set the shuffle state, returns a reference to the current AudioList instance for chaining. Note: NOTE: You do not call this manually, it must be called by the change event handler of an element. Concatenates one or more members to the end of the base array and returns the result as a new array. Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restarts. Temporary variables were added in v2.3.0. Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. Unstows the UI bar, so that it is fully accessible again. Twine2: Not special. Note: There's no way for the system to know ahead of time whether it's safe to re-execute a passage's contents. Some browsers, particularly mobile ones, will free up memory by unloading web pages that are running in the background. An array is a container that holds things. Note: If you want to return to a previously visited passage, rather than undo a moment within the history, see the <> macro or the previous() function. By default, it simply returns non-deterministic results from Math.random(), however, when the seedable PRNG has been enabled, via State.prng.init(), it returns deterministic results from the seeded PRNG instead. depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. older versions of Twine2 used a icon for the same purpose. Returns how much remains of the playlist's total playtime in seconds, Infinity if it contains any streams, or NaN if no metadata exists. Note: Returns the title of the most recent previous passage whose title does not match that of the active passage or an empty string, if there is no such passage. Causes any output generated within its body to be discarded, except for errors (which will be displayed). Due to how SugarCube stores the state history a few constructs are not supported within story variables. Does not modify the original. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. To install the package via NPM, use the following command: This is a reference on how to install SugarCube in Tweego, Twine2, and Twine1/Twee. Logical: The expression yields a boolean valuee.g..

You will also need to specify a .link-visited style that defines the properties visited links should have. Deletes the specified on-load handler, returning true if the handler existed or false if not. In these cases, audio will not automatically play on the starting passage, nor is it likely to play if initiated from within asynchronous codee.g., via. See UI API for more information. This method will not detect "code" passagesi.e., script, stylesheet, and widget passages. Returns a reference to the UIBar object for chaining. The callback is passed one parameter, the original destination passage title. The story's title is part of the story project. Returns whether playback of the playlist has ended. This only affects test mode. Warning: Warning: If no conditional expression is given, it is equivalent to specifying true. See the HTML and CSS docs for more information. Note: See Story API for more information. As with all special tags, media passage tags are case sensitive, so their spelling and capitalization must be exactly as shown. See the Macro API docs for more information. Note: Additionally, SugarCube's normal <> macro does not have an output element associated with it and is not, by default, a single-use link like its Harlowe equivalent. Several State API methods have moved to the new Engine API. Twine2: Not special. Note: Universal Inventory System (UInv) for Twine 2 / SugarCube 2 - GitHub - HiEv/UInv: Universal Inventory System (UInv) for Twine 2 / SugarCube 2. . .on() in the jQuery API docs for more information. Feel free to add your own if that makes localization easiere.g., for gender, plurals, and whatnot. Returns whether a playlist with the given list ID exists. Note: Does not modify the original. To enable test mode while starting at a specific passage, right-click on a passage and select the Test Play From Here context menu item. In test mode, SugarCube will wrap all macros, and some non-macro markupe.g., link & image markupwithin additional HTML elements, called "debug views" ("views" for short). sugarcube-2: macros: customMacroName: container: true anotherOne: {} If using *.twee-config . Outputs a string representation of the result of the given expression. See the Dialog API and UI API docs for more information. It is strongly recommended that you look into other methods to achieve your goals insteade.g., Config.navigation.override. Returns a reference to the current AudioTrack instance for chaining. Fullscreen API. Stops playback of the selected tracks and forces them to drop any existing data. Of the three Harlowe seems the most robusts, followed by SugarCube. Begins playback of the playlist or, failing that, sets the playlist to begin playback as soon as the player has interacted with the document.

While it renders content just as any other passage does, instead of displaying the rendered output as-is, it sifts through the output and builds its contents from the generated links contained therein. It consists of one or more right angle brackets, each additional one beyond the first signifying a level of nested blockquote. Returns a reference to the Dialog object for chaining. When a new moment is created, SugarCube stores the playthrough state to session storage. The UISystem API object has been split into two APIs Dialog and UI, and some of its methods have also changed. Warning: Unsupported object types, either native or custom, can be made compatible by implementing .clone() and .toJSON() methods for themsee the Non-generic object types (a.k.a. The document element. The documentation for each macro will tell you what it expects. Returns a reference to the current AudioRunner instance for chaining. The story metadata, like saves, is tied to the specific story it was generated with. Warning: Note: It is passed an abbreviated version of the associated passage's Passage instancecontaining only the tags, text, and title properties. Note: Does not modify the original. The Non-generic object types (a.k.a. Note: Code like <> seems to have no effect because the startup state is replaced by the of the incoming state, but they are still executed by the engine. For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. Most of the methods listed below are SugarCube extensions, with the rest being either JavaScript natives or bundled library methods that are listed here for their utilitythough, this is not an exhaustive list. Warning: Returns a timestamp representing the last time Engine.play() was called. While not specifically about SugarCube, the About Expressions section of the Twine1 reference documentation may also be helpful.

Returns a pseudo-random whole number (integer) within the range of the given bounds (inclusive)i.e., [min,max]. In mobile browsers and, more recently, most desktop browsers, playback must be initiated by the playergenerally via click/touch. Arrays have many built-in methods and other features, and SugarCube adds many more. The cycling options are populated via <> and/or <>. Shorthand for jQuery's .on() method applied to each of the audio elements. Happens before the rendering of the incoming passage. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. The number of moments contained within the story history is, generally, limited, via the Config.history.maxStates setting. Returns whether the dialog is currently open. Renders the given markup and appends it to the dialog's content area. Returns the value associated with the specified key from the story metadata store. Roughly equivalent to the :passagedisplay event. The directory and .py file names within the archive available for download are already properly matchedas sugarcube-2 and sugarcube-2.pyand to avoid issues it recommended that you simply do not rename them. Instead, use the metadata property. 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. Collects tracks, which must be set up via <>, into a group via its <> children. Gets or sets the track's repeating playback state (default: false). If its return value is falsy, the override is cancelled and navigation to the original destination continues unperturbed. See Passage API for more information. See Also: Note: See: Strings are iterated by Unicode code point, however, due to historic reasons they are comprised of, and indexed by, individual UTF-16 code units. In general, look to the .random() method instead. Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. followed by the template namee.g., ?yoloand are set up as functions-that-return-strings, strings, or arrays of eitherfrom which a random member is selected whenever the template is processed. If you wish to use custom backgrounds, either simply colors or with images, then you should place them on the body element. Even if it did know that, there's no way for it to know which operations may or may not have side-effectse.g., changing variables. Triggered after the rendering of the incoming passage. Hides the UI bar. Returns whether the passage with the given title occurred within the story history. with 2.0. Thus, all volume adjustments are ignored by the device, though muting should work normally. When used to set a value, returns a reference to the current AudioTrack instance for chaining. A range definition object should have some of the following properties: Note: Text Adventure Command Input macro for SugarCube 2 and Twine. The links go to the most recent release versions of each in SugarCube's source code repository. Note: All changes within this version are elective changes that you may address at your leisure.

If constructing the file URL from a shell path, ensure that either it does not contain escapes or you properly convert them into the correct URL percent-encoded form. Warning: This is only really useful within pure JavaScript code, as within TwineScript you may simply access temporary variables natively. Due to how the Twine2 automatic passage creation feature currently works, using the link markup form will cause a passage named $return to be created that will need to be deleted. If you want to change the font or color, then you'll need to change the styling of the macro-type class. Note: This setting has been deprecated and should no longer be used. Interrupts an in-progress fade of the track, or does nothing if no fade is progressing. All created passage elements will be children of this element. Returns the total number of filled slots. Because the custom style markup uses the same tokens to begin and end the markup, it cannot be nested within itself. You can have it hold numbers, text, and even other arrays! Fullscreen requests must be initiated by the player, generally via click/touchi.e., the request must be made as a result of player interaction; e.g., activating a button/link/etc whose code makes the request. Only useful when you have an asynchronous callback that invokes code/content that needs to access story and/or temporary variables shadowed by <>. Sets the maximum number of states (moments) to which the history is allowed to grow. They are defined via the Template API. For example: If you run the above, you'll see $x is 0. If necessary, however, you may manually change their valuesn.b. If no cases match and an optional <> case exists, which must be the final case, then its contents will be executed. Harlowe has stricter typing than SugarCube, requiring authors to call macros like (str:) or (num:) on variables to change their type. Does not modify the original. Warning: This section offers a list of SugarCube-specific events, triggered at various points during story operation. Returns an AudioRunner instance for the tracks matching the given selector. If the full path to the contents of the archive is something like: Then the file URL to it would be (note the changed slashes): The online SugarCube install, delivered by the jsDelivr CDN, supports only versions of Twine2 2.1. For example: Deprecated: A toggle definition object should have some of the following properties: Adds the named property to the settings object and a list control for it to the Settings dialog. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. Adds the named property to the settings object and a toggle control for it to the Settings dialog. Donate Requirements SugarCube's sole requirement is a modern web browser, and by modern I mean one released within the last several years (you do not need the absolute latest and greatest shiny). 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. Returns the string with its first Unicode code point converted to upper case. If omitted, the story title will be used instead. Roughly equivalent to the :passagestart event.

June 2017 in Help! Does not modify the original. Sets the starting passage, the very first passage that will be displayed. When setting the value to boolean true, you will likely also need to use the Config.saves.isAllowed property to disallow saving on the start passage. Gets or sets the track's current time in seconds. Opens the built-in settings dialog, which is populated from the Setting API. Removes fullscreen change event handlers. Returns the AudioList instance with the given list ID, or null on failure. The audio subsystem that supports the audio macros comes with some built-in limitations and it is strongly recommended that you familiarize yourself with them. Config object settings should be placed within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage). In particular, the parameter list for the Dialog.setup() method has changed. It is not a mechanism for moving data between stories. For example, a common use of <> is to perform various actions before forwarding the player to another passage. AudioTrack API, AudioRunner API, and AudioList API. 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. Randomly selects the given number of unique members from the base array and returns the selected members as a new array. Be very careful with these if your audio sources are on the network, as you are forcing players to begin downloading them. Elements that include either a data-init-passage or data-passage content attribute should not themselves contain additional elementssince such elements' contents are replaced each turn via their associated passage, any child elements would be lost. Does not modify the original. Configuration API. The Config.debug setting for more information. See the MDN article Media formats for HTML audio and video for more information on formats commonly supported in browserspay special attention to the Browser compatibility section. Warning: If you should chose to use an explicit seed, however, it is strongly recommended that you also enable additional entropy, otherwise all playthroughs for all players will be exactly the same. Used for pre-passage-display tasks, like redoing dynamic changes (happens before the rendering of each passage). Returns a reference to the current AudioTrack instance for chaining. Furthermore, it is no longer instantiated into the legacy macros objectwhich still exists, so SugarCube-compatible legacy macros will continue to work. Selects all internal link elements within the passage element whose passages do not exist within the story. Compilers supporting automatic creation of media passages: Warning (Twine2): Unfortunately, due to limitations in the current release of Twine1, the Build menu's Test Play menu item is not able to trigger test mode. Additional timed executions may be chained via <>. Returns whether any of the given members were found within the array. Concatenates one or more unique members to the end of the base array and returns the result as a new array. Shorthand for jQuery's .one() method applied to the audio element. Added to the active passage's container element, Added to the active passage's container element and. For more details you might want to see my "Arrays vs Generic Objects" article (part of the help file for my "Universal Inventory System" for Twine/SugarCube, or "UInv" for short). Selects the passage element. Attempting to do so will, usually, result in something that's non-functional. Arrays can be created by assigning a variable to the array literal, which is a pair of brackets ([]): <>. Caveat for Internet Explorer: SugarCube only supports IE 9. A macro definition object should have some of the following properties (only handler is absolutely required): Additional properties may be added for internal use. 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.
