All other non-generic object types, on the other hand, must be made compatible to be successfully stored within story variables. The load and playback states of tracks are not currently recorded within the active play session or saves. Deprecated: Deprecated: Note: Use the Edit Story JavaScript story editor menu item for scripts. When a new moment is created, SugarCube stores the playthrough state to session storage. The argument string after converting all TwineScript syntax elements into their native JavaScript counterparts. In use, replacement patterns are replaced recursively, so replacement strings may contain patterns whose replacements contain other patterns. Possible reasons include: no valid sources are registered, no sources are currently loaded, an error has occurred. Equivalent to wrapping the entire passage in a <> macro. Sets the value of the story or temporary variable by the given name. This macro has been deprecated and should no longer be used. See the _args special variable for its replacement. Returns the topmost (most recent) moment from the full in-play history (past + future). Wikifies the given content source(s) and appends the result to the target element(s). Determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). Removes event handlers from the track. There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. Some browsers, particularly mobile ones, will free up memory by unloading web pages that are running in the background. There are many differences between Harlowe and SugarCube, this guide will document some of the most critical you will need to account for if you're coming to SugarCube from a background in Harlowe. The config object has been renamed to Config and some of its properties have also changed. Determines whether the link-visited class is added to internal passage links that go to previously visited passagesi.e., the passage already exists within the story history. The DOM macros do have a limitation that you should familiarize yourself with. Select "Change Story Format" and check the box next to "Sugarcube." Download PDF version: Variables and Programming in Twine Generally, this means only when the variable's value will change between the time the asynchronous macro is invoked and when it's activatede.g., a loop variable. Note: Create a new passage, which will only be used as a media passageone per media source. Determines whether passage titles are combined with the story title, within the browser's/tab's titlebar, when passages are displayed. Warning: The versions that forward to a specific passage are largely unnecessary, as you could simply use a normal link, and exist solely for compatibility with the <> macro. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. The seed is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. In most cases of using variables in Twine, you will want to first "set" some value and then, at some later point, conditionally act from testing the value. To resolve instances where you do, however, you'll want to use either a temporary variable or a backquote expression. Returns whether playback of the track has ended. A decision I made was that all the individual strings in the array will also match the object's passage names. Determines whether saving is allowed within the current context. Returns the current state of the engine ("idle", "playing", "rendering"). See LoadScreen API for more information. In this case, once we assign $wumpus a room, we can delete that room from our $roomlist. SimpleAudio API. UI API. Note: SimpleAudio API, AudioTrack API, and AudioList API. If multiple passage titles are given, returns the logical-AND aggregate of the seti.e., true if all were found, false if any were not found. The Config API serves the same basic purpose. Returns whether the given substring was found within the string, starting the search at position. This method has been deprecated and should no longer be used. 3 4 4 comments Best Add a Comment ChapelR 4 yr. ago This macro is functionally identical to <) rather than an anchor element (). Deserializes the given save string, created via Save.serialize(), and loads the save. Normally, there will be only one such passage per turn, however, during passage navigation there may briefly be twothe incoming (a.k.a. Creates a list of single-use passage links. A sort of simple Twine parser. Does not modify the original. Essentially, a combination of <>. Returns whether the autosave is available and ready. Arrays have many built-in methods and other features, and SugarCube adds many more. Yes it is possible. A save operation details object will have the following properties: Deletes all currently registered on-save handlers. SugarCube does not support the Twine1.4+ vanilla story formats' tagged stylesheets. Click the Formats button in the right sidebar of Twine. Returns a formatted string, after replacing each format item in the given format string with the text equivalent of the corresponding argument's value. The SaveSystem API object has been renamed to Save and several of its methods have also changed, for better consistency with the other APIs. 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. Deprecated: Once unloaded, playback cannot occur until the track's data is loaded again. We'll cover some of these differences below. This means that some code points may span multiple code unitse.g., the character is one code point, but two code units. See Guide: Media Passages for more information. If you need a random member from an array-like object, use the Array.from() method to convert it to an array, then use .random(). As a consequence, you cannot use them directly within a passage to modify elements within said passage, since the elements they are targeting are still rendering, thus not yet on the page. Returns whether the slot saves are available and ready. Randomly removes the given number of members from the base array and returns the removed members as a new array. Note: A function, which causes the autosave to be updated for each passage where its return value is truthy. This can be thought of as a special, temporary saved story, which is automatically deleted after the player's current browsing session ends. You can see this effect by changing data outside the state. Used within <> macros. TwineHacker To Debug (Or Cheat) Twine {SugarCube} Variables based on extension from this f95 thread (thanks to @spectr3.9911) compatible with Chrome and Firefox Installation instructions Chrome: download repository and use Developer Mode then point directory 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. Displays the loading screen until all currently registered audio has either loaded to a playable state or aborted loading due to errors. Like in Harlowe, some SugarCube macros accept expressions and others accept discreet arguments. The affected elements are the story: banner, subtitle, author, caption, and menu. The Config.audio.pauseOnFadeToZero setting (default: true) controls whether tracks that have been faded to 0 volume (silent) are automatically paused. Warning: Repeatedly executes its contents. Additionally, SugarCube's normal <.ariaClick(), which can be done directly and with greater flexibility. Expired moments are recorded in a separate expired collection and can no longer be navigated to. Deprecated: Setting API. Does not modify the original. Note: Note: Returns the string with its first Unicode code point converted to upper case, according to any locale-specific rules. Requirements. Unfortunately, this means that the two objects are incompatible. See the State.prng.init() method for its replacement. Once initialized, the State.random() method and story functions, random() and randomFloat(), return deterministic results from the seeded PRNGby default, they return non-deterministic results from Math.random(). Warning: To prevent conflicts, it is strongly suggested that you specify a custom user namespacee.g., .myEventswhen attaching your own handlers. Returns an AudioRunner instance for the tracks matching the given selector. Note: It would probably help if you were more specific as to your goal. In Twine, return to your project library by clicking the house icon in the lower-left corner of the Twine window. Creates a new widget macro (henceforth, widget) with the given name. Not everyone has Stops playback of all currently registered tracks and force them to drop any existing data. The best example of an array is a pill container. Returns whether the history navigation was successful (should only fail if the index is not within the bounds of the full history). Returns the number of turns that have passed since the last instance of the passage with the given title occurred within the story history or -1 if it does not exist. 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. Request that the browser exit fullscreen mode. An array is a container that holds things. Returns a reference to the Dialog object for chaining. Note: It is strongly recommended that you use only one stylesheet passage. For example: That probably won't be very pleasing to the eye, however, so you will likely need several styles to make something that looks half-decent. If its return value is truthy, the save is allowed to continue unperturbed. Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. Warning: Returns a new array consisting of the flattened source array. All widgets may access arguments passed to them via the _args special variable. Triggered before the modification of the state history. The text of a container macro parsed into discrete payload objects by tag. Thus, storing them within story variables is generally wasteful. Returns whether any of the macro's ancestors passed the test implemented by the given filter function. State.prng.init() must be called during story initialization, within either your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or the StoryInit special passage. Does not modify the original. This macro has been deprecated and should no longer be used. Generates no output. This is only really useful within pure JavaScript code, as within TwineScript you may simply access story variables natively. Divides the current value on the left-hand side of the operator by the value on the right-hand side and assigns the remainder to the left-hand side. Returns a reference to the current jQuery object for chaining. The pull count is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. Adds the named property to the settings object and a toggle control for it to the Settings dialog. Indicates whether SugarCube is running in test mode, which enables debug views. 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. Skips ahead to the next track in the playlist, if any. SugarCube SugarCube is a free (gratis and libre) story format for Twine/Twee. The Fullscreen API comes with some built-in limitations: Returns the current fullscreen element or, if fullscreen mode is not active, null. This method has been deprecated and should no longer be used. Returns whether the track is loading data. The equivalent SugarCube code to achieve a similar result would be: Note: The easiest way to understand this is to look at what happens when you make some changes to StoryInit and then load a saved story from before those changes were made. Audio, image, video, and VTT passages are supported. Unstows the UI bar, so that it is fully accessible again. May be called either with the passage name or with a link markup. Instead, use Navigation Events or Tasks. Tip: It consists of one or more right angle brackets, each additional one beyond the first signifying a level of nested blockquote. Creates a link that silently executes its contents when clicked, optionally forwarding the player to another passage. Returns the string with its first Unicode code point converted to upper case. See Guide: Media Passages for more information. Does not modify the original. Concatenates one or more unique members to the end of the base array and returns the result as a new array. The callback is invoked each time a save is requested. Triggered after the rendering of the incoming passage. Note: Wikifies the given content source(s) and discards the result. 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. Configuration API. To jump to any moment/turn within the available history, select the moment/turn from the Turn select field. May be called with, optional, link text or with a link or image markup. 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). It must contain, at least, an element with the ID passages that will be the main passage display area. Note: Returns a new array consisting of the source array with all sub-array elements concatenated into it recursively up to the given depth. It is not a mechanism for moving data between stories. Returns whether a playlist with the given list ID exists. Arrays in Sugarcube have a built-in function that lets you delete elements from them by name. Note: Warning: Returns the total number (count) of played moments within the extended past history (expired + past). SugarCube is a free (gratis and libre) story format for Twine/Twee. Those that bundle SugarCube v2: Any series of Twine2 with a version 2.1. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. Load and integrate external JavaScript scripts. Evaluates the given expression and compares it to the value(s) within its <> children. For example: While every valid expressioneven those you might not expectyields a value, there are essentially two types of expressions: those with side effects and those without. See the Localization guide for more information. You will, very likely, never need to use State.current directly within your code. I've done it like this: $z= [ [1,2,3], [1,2,1], [4,4,0]] and it doesn't generate an error. Opens the built-in restart dialog, prompting the player to restart the story. Warning: If your content contains any SugarCube markup, you'll need to use the Dialog.wiki() method instead. Ideally, if you need to update UI bar content outside of the normal passage navigation update, then you should update only the specific areas you need to rather than the entire UI bar. Passage, tag, and variable names that have special meaning to SugarCube. It is unlikely that you will ever want to disable this setting. Loading is done asynchronously at run time, so if the script must be available within a tight time frame, then you should use the Promise returned by the function to ensure that the script is loaded before it is needed. Collects tracks, which must be set up via <>, into a playlist via its <> children. The second, and also mandatory, character of the variable name may be one of the following: the letters A though Z (in upper or lower case), the dollar sign, and the underscore (i.e., A-Za-z$_)after their initial use as the sigil, the dollar sign and underscore become regular variable characters. prerender tasks have been deprecated and should no longer be used. Returns the last Unicode code point within the string. See Config API for more information. This setting property has been updated to accept function values and its acceptance of string values has been deprecated. The core of what it does is simply to wrap a call to, This method has been deprecated in favor of the, This method has been deprecated and should no longer be used. 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. Returns the total number of filled slots. See the Save.onLoad.add() method for its replacement. Silently executes its contents as pure JavaScript codei.e., it performs no story or temporary variable substitution or TwineScript operator processing. Deletes the specified on-save handler, returning true if the handler existed or false if not. Moves backward one moment within the full history (past + future), if possible, activating and showing the moment moved to. The story's title is part of the story project. All created passage elements will be children of this element. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. Strings localization object. There are three forms: a conditional-only form, a 3-part conditional form, and a range form. Shorthand for jQuery's .one() method applied to each of the audio elements. The story title is not included in updates because SugarCube uses it as the basis for the key used to store and load data used when playing the story and for saves. Note: Note: SugarCube automatically stores the current playthrough state to the browser's session storage whenever a new moment is created. Those that do not bundle SugarCube v2: Only the older Twine2.0 series. The following types of values are natively supported by SugarCube and may be safely used within story and temporary variables. Deprecated: See UI API for more information. For example, the following will not work because the macro parser will think that you're passing five discrete arguments, rather than a single expression: You could solve the problem by using a temporary variable to hold the result of the expression, then pass that to the macro. Shorthand for jQuery's .off() method applied to the audio element. Does not modify the original. [SugarCube 2.21.0] Two-dimensional arrays. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. The majority of newer SugarCube versions do not have any changes that would require an update. <> macro events allow the execution of JavaScript code at specific points during typing. Note: As with <>, <> can accept link markup as its argument: SugarCube's user input macros, like <>, cannot be nested inside a <> macro, as you might do with a (prompt:) and a (set:) in Harlowe. Attempting to do so will, usually, result in something that's non-functional. Warning: Returns the title of the passage associated with the active (present) moment. May be terminated by a <> macro. Global event triggered once just before the dismissal of the loading screen at startup. Thus, any groups or playlists containing the deleted track should be rebuilt. Tip: When the story is restarted by SugarCube rather than refreshed via the browser, the playthrough session, if any, is not loaded. 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). Additionally, SugarCube's link macro accepts a passage argument, that, if included, turns any <.on() in the jQuery API docs for more information. Starts playback of the selected tracks and fades them from the specified volume level to 0 (silent) over the specified number of seconds. Help with arrays in sugarcube 2. Deprecated: Sugarcube Documentation http://www.motoslave.net/sugarcube/2/ Twine is a free online tool that allows you to create interactive stories like Choose Your Own Adventure books. Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importScripts(). blazing fast internet with unlimited dataespecially true for mobile users. Used to populate the contents of the Share dialog. Executes its contents and prepends the output to the contents of the selected element(s). You should see one line, press the arrow on the side to see all of it. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. Provides access to browsers' fullscreen functionality. To avoid this problem, it's suggested that you use the separate argument form of the <> macro for its replacement. Browsers are not currently required to honor the navigationUI setting. Arithmetic: The expression yields a number valuee.g.. The Config object controls various aspects of SugarCube's behavior. A format item has the syntax {index[,alignment]}, square-brackets denoting optional elements. The story history contains moments (states) created during play. Values may be of most primitive types and some object types, see Supported Types for more information. A set of opening and closing tagsi.e., defines the verbatim HTML markup. When used to set the volume, returns a reference to the current AudioTrack instance for chaining. Multiplies the current value on the left-hand side of the operator by the value on the right-hand side and assigns the result to the left-hand side. When used to set the volume, returns a reference to the current AudioList instance for chaining. Etc. Returns whether the named macro tag exists. Since it is possible to navigate the historyi.e., move backward and forward though the moments within the historyit may contain both past momentsi.e., moments that have been playedand future momentsi.e., moments that had been played, but have been rewound/undone, yet are still available to be restored. Outputs a copy of the contents of the selected element(s). Note: Note: As an example, the default replacement strings make use of this to handle various warning intros and outros. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). Several State API methods have moved to the new Engine API. If no cases match and an optional <> case exists, which must be the final case, then its contents will be executed. You can use custom style markup or HTML to create the elements, and then target them with a query selector. See Save API for more information. Returns the processed text of the passage, created from applying nobr tag and image passage processing to its raw text. Note: Removes and returns the last member from the array, or undefined if the array is empty. Note: Most interactive elementse.g., passage links, interactive macros, etc.cannot be properly copied via <>. The handler is passed one parameter, the save object to be processed.
