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: If no conditional expression is given, it is equivalent to specifying true. Used to populate the story's banner area in the UI bar (element ID: story-banner). 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). older versions of Twine2 used a icon for the same purpose. See the State API docs for more information. Note: Returns a reference to the current jQuery object for chaining. Creates a checkbox, used to modify the value of the variable with the given name. If you have a property that uses an array of values, you will be able to use the various "tag" functions to . May eat line-breaks in certain situations. As all special passage populated sections are updated it is recommended that UIBar.update() be used sparingly. Deprecated: 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. Returns the playlist's current time in seconds, or NaN if no metadata exists. See <> for more information. The pull count is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. Note: Warning: Then close the dialog box. Each link removes itself and all other <> links to the same passage after being activated. Consider the following Harlowe link macros: The equivalent SugarCube code for each link might look something like this: SugarCube's <> macros can also accept the link markup as an argument: Note: 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. This method has been deprecated and should no longer be used. This setting property has been updated to accept function values and its acceptance of string values has been deprecated. Appends the given content to the dialog's content area. Replacement patterns have the format {NAME}e.g., {identity}where NAME is the name of a property within either the l10nStrings object or, in a few cases, an object supplied locally where the string is usedthese instances will be commented. These instances will be noted. Fullscreen API. You will also need some CSS styles to make this workexamples given below. SugarCube 2.x - The current version of SugarCube. Sylen. Returns whether, at least, some of the track's data has been loaded. Property attributes, including getters/setters, and symbol properties. Creates a single-use passage link that deactivates itself and all other <> links within the originating passage when activated. Passage render. As an example, the default replacement strings make use of this to handle various warning intros and outros. You will, very likely, never need to use State.top directly within your code. The callback is passed one parameter, the original destination passage title. May be called either with a list of passages, with a list of link markup, or with a list of image markup. Thus, if you need either to be recoverable, then you'll have to handle that yourself. When using Twine1/Twee, it is strongly recommended that you use only a single stylesheet tagged passage. Call this only after populating the dialog with content. Circular references. Does not modify the original. Returns the number of milliseconds that have passed since the current passage was rendered to the page. The capitalization and punctuation used within the default replacement strings is deliberate, especially within the error and warning strings. Returns the given code string, and optional data chunk, wrapped within the JSON deserialization revive wrapper. Returns a timestamp representing the last time Engine.play() was called. Returns whether any of the given members were found within the array. If there were errors, an exception is thrown. Returns a reference to the current AudioRunner instance for chaining. Engine API. 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. For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. Activates the moment at the given offset from the active (present) moment within the full state history and show it. The API automatically calls this method at startup, so you should never need to call this method manually. In SugarCube, you instead open and close the <> macro itself: Some macros in Harlowe and SugarCube share a name but work a bit differently. Registers the passage as a VTT passage. Template API. You cannot obtain data about the closing dialog from the dialog itselfe.g., title or classeswhen using the :dialogclosed event, as the dialog has already closed and been reset by the time the event is fired. To simply add a delay to the dismissal of the loading screen to hide initial flashes of unstyled content (FOUC)e.g., style changes and page reflowsyou do not need to use this API. For instances where you need to run some pure JavaScript and don't want to waste time performing extra processing on code that has no story or temporary variables or TwineScript operators in it and/or worry about the parser possibly clobbering the code. Widgets allow you to create macros by using the standard macros and markup that you use normally within your story. Manages the Settings dialog and settings object. The StoryInit special passage is normally the best place to set up tracks. Deprecated: There are ways to turn webapps into apps for mobile phones and Windows/Linux etc, but it's still running in a web browser under the hood. Does not modify the original. Returns whether the track's sources are currently unloaded. Warning: See the <> macro for its replacement. Note: Note: Note: Only deletes the groups themselves, does not affect their component tracks. Track event triggered when playback is stopped after .stop() or .stop() is calledeither manually or as part of another process. For example, if some story passages were tagged with forest, then styles for those forest passages might look like this: These are SugarCube's built-in stylesheets, in order of load/cascade. Iterates through all enumerable entries of the given collection. The exactly equivalent call is: .flat(Infinity). Outputs its contents a charactertechnically, a code pointat a time, mimicking a teletype/typewriter. Terminates the execution of the current <>. Selects the element that contains passage elements. Sets the maximum number of states (moments) to which the history is allowed to grow. 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. You should virtually never need to use the verbatim HTML markup. Elements that are already part of the page, on the other hand, present no issues. 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. Macro API. The StoryInit special passage is normally the best place to set up playlists. Returns whether the engine is processing a turni.e., passage navigation has been triggered. The IFID (Interactive Fiction IDentifier) of the story, if any. Returns the first Unicode code point within the string. Comments used within passage markup are not rendered into the page output. Note: 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. 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. 3 4 4 comments Best Add a Comment ChapelR 4 yr. ago There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. Shows the UI bar. SugarCube features a configurable autosave system. 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. [SugarCube 2.21.0] Two-dimensional arrays. Deprecated: Do not add a widget tag to any of the specially named passages and attempt to define your widgets there. 558 30K views 7 years ago Introduction to Twine In this new series, I cover the process of writing interactive fiction using Twine and the Sugarcube story format. Removes and returns the last member from the array, or undefined if the array is empty. Warning: 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. Save objects have some of the following properties: The state object has the following properties: Each moment object has the following properties: Deletes all slot saves and the autosave, if it's enabled. This method has been deprecated and should no longer be used. Because replacement is recursive, care must be taken to ensure infinite loops are not createdthe system will detect an infinite loop and throw an error. Returns the number of moments within the full in-play history (past + future). There are two primary branches of Twine2 as far as SugarCube is concerned: Regardless of the version of Twine2 you're using, follow these instructions to install a local copy of SugarCube v2: Note: This is only really useful within pure JavaScript code, as within TwineScript you may simply access temporary variables natively. Alternatively, if you simply want the UI bar gone completely and permanently, either using UIBar.destroy() or the StoryInterface special passage may be a better choice. Executes its contents and appends the output to the contents of the selected element(s). 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). Note: The $args special variable has been deprecated and should no longer be used. The active passage's tags will be added to its data-tags attribute (see: Passage Conversions). If omitted, the story title will be used instead. Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. Selects all internal link elements within the passage elemente.g., passage and macro links. See Fullscreen API for more information. Removes the audio group with the given ID. If necessary, you may also use multiple tags by switching from .includes() to .includesAny() in the above example. This method has been deprecated and should no longer be used. Sets the selected tracks' volume mute state (default: false). Only the primitives, generic objects, some JavaScript natives (specifically: Array, Date, Map, RegExp, and Set), and DOM node objects are supported by default. Alias for jQuery, by default. Renders the message prefixed with the name of the macro and returns false. In general, look to the .random() method instead. Shorthand for jQuery's .one() method applied to each of the audio elements. Returns a reference to the current AudioRunner instance for chaining. Wikifies the given content source(s) and appends the result to the target element(s). Begins playback of the playlist or, failing that, sets the playlist to begin playback as soon as the player has interacted with the document. See the Test Mode guide for more information. Used for post-passage-display tasks, like redoing dynamic changes (happens after the rendering and display of each passage). Audio lists (playlists) are useful for playing tracks in a sequencei.e., one after another. Meaning that when you pass a variable as an argument, its value is passed to the macro rather than its name. Additionally, it is strongly recommended that you do not specify any arguments to State.prng.init() and allow it to automatically seed itself. Twine 2.3: SugarCube 2.28: Arrays 2,500 views May 16, 2019 23 Dislike Share Save Dan Cox 3.68K subscribers This video reviews arrays in SugarCube 2.28 as part of Twine 2.3.. It is further strongly suggested that you provide that same custom user namespace when removing them. Harlowe is the default style for Twine 2.0 and uses a syntax that is different than Sugarcube. Attaches event handlers to the track. You may, however, forcibly enable it if you need to for some reasone.g., if you're using another compiler, which doesn't offer a way to enable test mode. Due to a flaw in the current release of Twine1/Twee (v1.4.2), if you rename the directory included in the archive (or simply copy its contents to your current SugarCube v2 install), then you must ensure that the file with the extension .py (the story format's custom Twine1 Header class file) within is named the same as the directoryi.e., the name of the directory and .py file must match. Thus, all volume adjustments are ignored by the device, though muting should work normally. Returns the total number (count) of played moments within the extended past history (expired + past). 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. 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 <>. SugarCube does not trim whitespace from the contents of <>/<> macros, so that authors don't have to resort to various kludges to get whitespace where they want it. Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. Removes fullscreen change event handlers. The sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. Renders the selected passage into the target element, replacing any existing content, and returns the element. active) and outgoing passages. See LoadScreen API for more information. If you need to run the same code on multiple passages, consider using the PassageDone special passage or, for a JavaScript/TwineScript solution, a :passagedisplay event instead. Collects tracks, which must be set up via <>, into a playlist via its <> children. Expressions are simply units of code that yield values when evaluated. Not generally necessary, however, some browsers render slower than others and may need a little extra time to get a media-heavy page done. Loading is done asynchronously at run time, so if the script must be available within a tight time frame, then you should use the Promise returned by the function to ensure that the script is loaded before it is needed. Warning: Executes its contents and prepends the output to the contents of the selected element(s). Global event triggered as the first step in closing the dialog when Dialog.close() is called. For example, a common use of <>, into a group via its <> children. If you wish to use custom backgrounds, either simply colors or with images, then you should place them on the body element. The parser instance that generated the macro call. Use of this macro is only necessary when you need to localize a variable's value for use with an asynchronous macroi.e., a macro whose contents are executed at some later time, rather than when it's invoked; e.g., interactive macros, <>, <>. Returns a reference to the UIBar object for chaining. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. Returns the number of currently registered on-save handlers. You will, in all likelihood, use expressions most often within macrose.g., <>, <>, <>, <>. Returns the title of the active (present) passage. Once the code has been fully executed, the contents of the buffer, if any, will be output. 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. The playthrough session feature is occasionally confused with the autosave feature, but they are in fact distinct systems.
