This method will not return "code" passagesi.e., script, stylesheet, and widget passages. See the HTML and CSS docs for more information. When used to set the mute state, returns a reference to the current AudioList instance for chaining. Returns a reference to the current jQuery object for chaining. Navigating back to a previous passage, for whatever reason, can be problematic. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . Returns whether the UI bar is currently hidden. Note: If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. Makes the target element(s) WAI-ARIA-compatible clickablesmeaning that various accessibility attributes are set and, in addition to mouse clicks, enter/return and spacebar key presses also activate them. The parser instance that generated the macro call. Warning: Note: Removes event handlers from the track. Returns whether the engine is rendering the incoming passage. Happens at the end of passage navigation. Create a new passage, which will only be used as a media passageone per media source. Note: This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. Triggered at the end of passage navigation. Note: Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. In case you needed to do more than simply load the save, you may do something like the following: Returns a save as a serialized string, or null if saving is not allowed within the current context. A Twine Cheat Sheet (a start, at least) Story Formats There are three basic story formats: Harlowe Snowman SugarCube Unfortunately, not all of the formatting syntax below work with each of these formats. Several UI API methods have moved to the new Dialog API. SugarCube is a free (gratis and libre) story format for Twine/Twee. Harlowe's implementation of data types differs significantly from SugarCube's. Setting API method calls must be placed within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or settings will not function correctly. Thus, storing them within story variables is generally wasteful. SugarCube preserves the state of the story as it's being played in a number of ways to both prevent the loss of progress and allow players to save stories. Arrays in Sugarcube have a built-in function that lets you delete elements from them by name. Several things occur each and every time startup happens, regardless of whether or not a playthrough session will be restored, an autosave loaded, or the starting passage run. Unless localized by use of the <> macro, any story or other temporary variables used within widgets are part of a story's normal variable store, so care must be taken not to accidentally either overwrite or pick up an existing value. In SugarCube you can convert them if you need to. Note: Passage end. Essentially, a combination of <> and <>. 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. The story metadata, like saves, is tied to the specific story it was generated with. classes) guide for more information. Twine1/Twee: Required. For example: There's also a macro-type-done class that is added to text that has finished typing, which may be used to style it differently from actively typing text. The very first, and mandatory, character is their sigil, which denotes whether they are a story or temporary variable. Attaches fullscreen error event handlers. Selects the passage element. Stows the UI bar, so that it takes up less space. For example, you might use the story variable $name to store the main player character's name or the story variable $cash to store how much money the player has on hand. You'll need to tag each and every one of your menu passages with noreturnyou may use any tag you wish (e.g., menu, inventory), just ensure you change the name in the code if you decide upon another. Returns a reference to the UIBar object for chaining. Adds a playlist with the given list ID. Configurable, see Config.passages.start for more information. And feedback from the folks over at the Twine Games Discord Server. Allows the destination of passage navigation to be overridden. Does not modify the original. Returns the number clamped to the specified bounds. SugarCube automatically stores the current playthrough state to the browser's session storage whenever a new moment is created. Does not currently remove the track from either groups or playlists. The history allows players to navigate through these moments. To pass expressions or the results of functions to macros as an argument, you must wrap the expression in backquotes (`). If you need that kind of information from the dialog itself, then you may use the :dialogclosing event instead. Warning: It is replaced by the Setting API and settings special variable. Returns the Passage object referenced by the given title, or an empty Passage object on failure. Do not add a widget tag to any of the specially named passages and attempt to define your widgets there. Displays the loading screen until all currently registered audio tracks have either loaded to a playable state or aborted loading due to errors. Note: Returns a reference to the Dialog object for chaining. May be called with, optional, link text or with a link or image markup. Starts playback of the selected tracks and fades them from the specified volume level to 1 (loudest) over the specified number of seconds. Due to how SugarCube stores the state history a few constructs are not supported within story variables. 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. See Also: When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. In the above example, if you save the story after reaching the passage called another passage, the $var variable will be saved in the state as 1, as you would expect. See <> for more information. Note: Function templates should return a string, which may itself contain markup. SugarCube provides a variety of functions and methods that may be used instead, and standard JavaScript functions and methods may also be used. See the Engine API docs for more information. Thus, any groups or playlists containing the deleted track should be rebuilt. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. active) and outgoing passages. The data-init-passage attribute causes the element to be updated once at initialization, while the data-passage attribute causes the element to be updated upon each passage navigation. You may forcibly enable test mode manually by setting the Config object's debug property to true. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. Returns whether any of the target WAI-ARIA-compatible clickable element(s) are disabled. [SugarCube 2.21.0] Two-dimensional arrays. Terminates the execution of the current <>. SugarCube, like JavaScript, will try to make sense of expressions passed to it by coercing their values if necessary: In the above case, since the string value "2" cannot be added to a number value, the number value is coerced into a string, and the two strings are then concatenated. Executes its contents and prepends the output to the contents of the selected element(s). Removes and returns a random member from the base array. May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. When used to set the volume, returns a reference to the current AudioTrack instance for chaining. Warning: Returns the topmost (most recent) moment from the full in-play history (past + future). See Also: Note: Note: Note: The Config.debug setting for more information. Function behavior is immutable. 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. Returns a reference to the Dialog object for chaining. Does not affect script or stylesheet tagged passages, for Twine1/Twee. If multiple passage titles are given, returns the lowest count. Returns a timestamp representing the last time Engine.play() was called. Returns the number of moments within the past in-play history (past only). Those that do not bundle SugarCube v2: Only the older Twine2.0 series. Twine2: Not special. Note: LoadScreen API. Reloading the page or revisiting a passage may not restore the state of some interactive macros, so it is recommended that you only use them in instances where this will not be an issue or where you can work around it. See the Test Mode guide for more information. See Also: Removes all of the members from the array that pass the test implemented by the given predicate function and returns a new array containing the removed members. Most interactive elementse.g., passage links, interactive macros, etc.cannot be properly copied via <>. The equivalent SugarCube code works a bit differently: SugarCube does not terminate the parsing of the calling passage, so some care is required when calling <>. The autosave feature is occasionally confused with the playthrough session feature, but they are in fact distinct systems. If necessary, you may also use multiple tags by switching from .includes() to .includesAny() in the above example. Caches an audio track for use by the other audio macros. Appends one or more unique members to the end of the base array and returns its new length. If you only need to print the value of a TwineScript variable, then you may simply include it in your normal passage text and it will be printed automatically via the naked variable markup. May be called either with the passage name and link text as separate arguments, with a link markup, or with a image markup. Returns whether playback of the playlist has been stopped. SimpleAudio API. you'll need to call the Setting.save() after having done so. Used to populate the story's menu items in the UI bar (element ID: menu-story). The DOM macros do have a limitation that you should familiarize yourself with. Warning: In Twine, a variable is a way of storing and acting on data of some sort. All changes within this version are breaking changes that you must address immediately. Note: In SugarCube, they come in two types: story variables and temporary variables. 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. TypeScript bindings for SugarCube APIs can found as the Definitely Typed package: @types/twine-sugarcube. May be called either with the passage name or with a link markup. The Config API serves the same basic purpose. Harlowe has stricter typing than SugarCube, requiring authors to call macros like (str:) or (num:) on variables to change their type. This macro is functionally identical to <>, save that it also encodes HTML special characters in the output. Returns the last Unicode code point within the string. 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. This is not necessarily the same as the current state of the story: because moment creation is tied to passage navigation, changes that occur between one passage navigation and the next are not part of the current moment and will not be preserved by a moment until the next navigation, when the next moment is created. Returns the last member from the array. Returns a callback function that wraps the specified callback functions to provide access to the variable shadowing system used by the <> macro. Concatenates one or more members to the end of the base array and returns the result as a new array. The strings API object has been replaced by the l10nStrings object. Returns whether an audio group with the given group ID exists. Audio, image, video, and VTT passages are supported. However, this means that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. The Share dialog only displays linksspecifically, anything that creates an anchor element (). Local event triggered on the typing wrapper when the typing of a section starts. Returns how much remains of the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. 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. SugarCube is available in two major versions: the current 2.x series and the legacy 1.x series. Multiple <> macros may be set up to modify the same variable, which makes them part of a radio button group.
