The typed text has no default styling. Deprecated: Note: Does not modify the original. Returns the first member from the array. Note: 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. 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. Note: Begins playback of the track or, failing that, sets the track to begin playback as soon as the player has interacted with the document. Note: All created passage elements will be children of this element. If no autosave exists, then the starting passage is rendered. Note: Using State.active directly is generally unnecessary as there exist a number of shortcut properties, State.passage and State.variables, and story functions, passage() and variables(), which grant access to its normal properties. It has always been required that the call happen during story initialization, the only change is the throwing of the error. In SugarCube, they come in two types: story variables and temporary variables. 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. Global event triggered when all <> macros within a passage have completed. If you want to play tracks in a sequence, then you want a playlist instead. Unused by SugarCube. 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. 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. Adds the named property to the settings object and a toggle control for it to the Settings dialog. The line continuation markup performs a similar function, though in a slightly different way. Does not modify the original. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. If its return value is falsy, the override is cancelled and navigation to the original destination continues unperturbed. Returns the number of passages within the story history that are tagged with all of the given tags. 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. Skips ahead to the next track in the playlist, if any. Create a save, then edit the code as follows: Running that, you'll see $x is 0 and $y is 1. Documentation, downloads, and the like can be found within each section. For game-oriented projects, as opposed to more story-oriented interactive fiction, a setting of 1 is strongly recommended. Arrays have many built-in methods and other features, and SugarCube adds many more. Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. Requirements. Expressions are simply units of code that yield values when evaluated. Determines whether rendering passages have their leading/trailing newlines removed and all remaining sequences of newlines replaced with single spaces before they're rendered. Config.saves.autosave setting, Config.saves.autoload setting, and Save API: Autosave. Setting API. Harlowe has stricter typing than SugarCube, requiring authors to call macros like (str:) or (num:) on variables to change their type. Note: Note: Tag it with the appropriate media passage special tag, and only that tagsee below. Sets the selected tracks' current time in seconds. 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. If you plan on using interactive macros within a loop you will likely need to use the. 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. 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. Removes and returns a random member from the base array. Returns the first Unicode code point within the string. The strings API object has been replaced by the l10nStrings object. 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. Note: Tip: The $args special variable has been deprecated and should no longer be used. Returns whether the named macro tag exists. The story metadata store is not, and should not be used as, a replacement for saves. Returns whether the named template exists. Deprecated: Used for post-passage-display tasks, like redoing dynamic changes (happens after the rendering and display of each passage). A sort of simple Twine parser. You may not remove the predefined group IDs (:all, :looped, :muted, :paused, :playing) or the :not group modifier. Shorthand for jQuery's .one() method applied to each of the audio elements. The body of the page. Story API. For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. In SugarCube, they come in two types: story variables and temporary variables. Returns whether the given member was found within the array, starting the search at position. If SugarCube is reloaded by one of its own built-in restart methods, then the session is. Note: Properties on the strings localization object (l10nStrings) should be set within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) to override the defaults. Returns the number of times that the given member was found within the array, starting the search at position. Registers the passage as <> macro definitions, which are loaded during startup. You should see one line, press the arrow on the side to see all of it. Returns a timestamp representing the last time Engine.play() was called. Returns whether a fade is in-progress on the track. Controls the playback of audio tracks, which must be set up via <>. Returns a new array filled with all Passage objects that pass the test implemented by the given predicate function or an empty array, if no objects pass. Returns a random value from its given arguments. Warning: Selects all internal link elements within the passage elemente.g., passage and macro links. Requires tracks to be set up via <>. Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. State.top is not a synonym for State.active. Request that the browser enter fullscreen mode. Note: Returns whether the full in-play history (past + future) is empty. Occasionally, however, macros will need the name of a variable rather than its valuee.g., data input macros like <>so that they may modify the variable. If multiple passage titles are given, returns the lowest count (which can be -1). Note: Sugarcube is a legacy version that supports the features and syntax of earlier Twine 1.x versions. Feel free to add your own if that makes localization easiere.g., for gender, plurals, and whatnot. SimpleAudio events allow the execution of JavaScript code at specific points during audio playback. private browsing modes do interfere with this. Then close the dialog box. Global event triggered as the last step in opening the dialog when Dialog.open() is called. Sets the maximum number of iterations allowed before the <> macro conditional forms are terminated with an error. Note: Returns whether playback of the track has ended. Manages the Settings dialog and settings object. postrender tasks have been deprecated and should no longer be used. This method has been deprecated and should no longer be used. Returns whether any valid sources were registered. It should be plain text, containing no code, markup, or macros of any kind. You may, however, simply use the Test Play From Here context menu item on the Start passage to achieve the same result. Does not currently remove the track from either groups or playlists. 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. Sets the integer delay (in milliseconds) before the loading screen is dismissed, once the document has signaled its readiness. When used to set the volume, returns a reference to the current AudioList instance for chaining. Returns whether the specified key exists within the story metadata store. Widgets should always be defined within a widget-tagged passageany widgets that are not may be lost on page reloadand you may use as few or as many such passages as you desire. Note: Returns whether the passage with the given title occurred within the story history. 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 whether the operation was successful. The StoryInit special passage is normally the best place to set up playlists. 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. For example: (not an exhaustive list). Removes all of the members at the given indices from the array and returns a new array containing the removed members. 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. Warning: If you've removed/hidden the UI bar, a construct like the following will allow you to toggle the views on and off: Note: Warning: Adds an audio group with the given group ID. Track event triggered when playback is stopped after .stop() or .stop() is calledeither manually or as part of another process. Returns whether the engine is processing a turni.e., passage navigation has been triggered. The most interesting of which, from an end-user's standpoint, are 410. Note: Audio, image, video, and VTT passages are supported. Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. In versions of SugarCube v2.23.0, the debugging interface offers additional tools, namely variable watches and arbitrary history navigation. Deprecated: The seed is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. 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. Load and integrate external CSS stylesheets. Those that want an expression are fairly straightforward, as you simply supply an expression. 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. Note: 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. Removes and returns a random member from the base array. String: The expression yields a string valuee.g.. Normally, those aren't issues as you should not need to use the result of an expression as an argument terribly often. Audio lists (playlists) are useful for playing tracks in a sequencei.e., one after another. Does not modify the original. Returns the AudioTrack instance with the given track ID, or null on failure. Returns the total number (count) of played moments within the extended past history (expired + past). An asterisk (*) or number sign (#) that begins a line defines a member of the unordered or ordered list markup, respectively. Non-generic object types (a.k.a. There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. When used to set the volume, returns a reference to the current AudioTrack instance for chaining. Math.random() is no longer replaced by the integrated seedable PRNG when State.prng.init() is called. The sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. 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. Note: Note: Registers the passage as an image passage. If necessary, you may also use multiple tags by switching from .includes() to .includesAny() in the above example. For example: A better solution, however, would be to use a backquote1 (`) expression, which is really just a special form of quoting available in macro arguments that causes the contents of the backquotes to be evaluated and then yields the result as a singular argument. Gets or sets the track's volume level (default: 1). All properties of Passage objects should be treated as if they were read-only, as modifying them could result in unexpected behavior. Identical to calling .map().flat(). Starts playback of the track and fades it between the specified starting and destination volume levels over the specified number of seconds. Like in Harlowe, some SugarCube macros accept expressions and others accept discreet arguments. Returns a callback function that wraps the specified callback functions to provide access to the variable shadowing system used by the <> macro. And feedback from the folks over at the Twine Games Discord Server. If you don't know what that means, then this API is likely not for you. Deprecated: 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: May eat line-breaks in certain situations. SugarCube, like JavaScript, uses dynamic typing. Appends one or more members to the end of the base array and returns its new length. Attaches fullscreen change event handlers. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. Note: Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. Silently executes its contents when the incoming passage is done rendering and has been added to the page. Does not modify the original. 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 current AudioRunner instance for chaining. Determines whether outgoing passage transitions are enabled. 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. 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. Note: This process is the same regardless of where the loaded state is coming from: it could be a normal save, the autosave, or the playthrough session. Essentially, a combination of <> and <>. See the <> macro for its replacement. The Config.audio.pauseOnFadeToZero setting (default: true) determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). This method will not return "code" passagesi.e., script, stylesheet, and widget passages. If multiple passage titles are given, returns the lowest count. ---- Like what. Any supported object type may itself contain any supported primitive or object type. First, the CSS, JavaScript, and Widget sections are processed. The starting passage, the first passage displayed. > Title says it all. Selects all internal link elements within the passage element whose passages are within the in-play story historyi.e., passages the player has been to before. 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. See the .includesAll() method for its replacement. Instead of storing any "static" data (data which won't change during the entire game, e.g. A set of four hyphen/minus characters (-) that begins a line defines the horizontal rule markup. See Engine API for more information. Warning: 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. If you're on Linux, right-click on the file and select Copy. Each event is represented by an object that has properties that may be used to get additional information about what happened. State.has() does not check expired moments. At the very least you will need to specify a .passage-out style that defines the transition's end state. Registers the passage into the Jump To menu. Injecting additional <> macro invocations after a :typingcomplete event has been fired will cause another event to eventually be generated, since you're creating a new sequence of typing. See the Dialog API and UI API docs for more information. Creates a new widget macro (henceforth, widget) with the given name. Determines whether the autosave is created/updated when passages are displayed. In Twine, you can combine the Set Macro with an If Macro to test is some condition is "true.". This method has been deprecated and should no longer be used. Function templates should return a string, which may itself contain markup. Tip: Browsers are not currently required to honor the navigationUI setting. When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. This functionally refreshes the webpage, and can cause users to lose their progress. Note: Attaches event handlers to the track. Determines whether the <> macro returns an error when the = assignment operator is used within its conditionale.g., <>. If you simply need a passage link that modifies variables, both the link markup and image markup offer setter variants. Possible reasons include: no valid sources are registered, no sources are currently loaded, an error has occurred. represents whitespace that will be removed, represents line breaks). If no name is given, resets all settings. The autosave feature is occasionally confused with the playthrough session feature, but they are in fact distinct systems. Removes event handlers from the selected tracks. See Setting API for more information. Gets or sets the mute-on-hidden state for the master volume (default: false). Note: Thus, it is only truly useful if you plan to upgrade out-of-date saves via a Config.saves.onLoad callback. <> macro events allow the execution of JavaScript code at specific points during typing. To modify the values contained within variables, see the <> macro and setter links. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . The DOM ID of the story, created from the slugified story title. State API. It would probably help if you were more specific as to your goal. Note: 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. When a saved story is loaded, the state loaded from the save replaces the current state. Fullscreen API. most recent commit 3 months ago. Local event triggered on the typing wrapper when the typing of a section starts. Triggered after the rendering of the incoming passage. SugarCube automatically stores the current playthrough state to the browser's session storage whenever a new moment is created. Returns a reference to the UIBar object for chaining. Note: The _contents special variable is used internally, by container widgets, to store the contents they enclose. Make sure to keep the files together if you move them out of the included directory. Note: Returns a new array consisting of the result of calling the given mapping function on every element in the source array and then concatenating all sub-array elements into it recursively up to a depth of 1. To delete a watch, click the button next to its name in the watch panel. Note: The loading process is as described in SimpleAudio.load(). The exactly equivalent call is: .flat(Infinity). This is not an exhaustive list. Determines whether saving to disk is enabled on mobile devicesi.e., smartphones, tablets, etc. blazing fast internet with unlimited dataespecially true for mobile users. prerender tasks have been deprecated and should no longer be used. See Guide: Media Passages for more information. To do so, click on the name of your story in its main "story map" view. Unsets story $variables and temporary _variables. SugarCube v2.36. Should the history exceed the limit, states will be dropped from the past (oldest first). When the story is restarted by SugarCube rather than refreshed via the browser, the playthrough session, if any, is not loaded. To prevent conflicts, it is strongly suggested that you specify a custom user namespacee.g., .myEventswhen attaching your own handlers. No line-break control mechanisms are used in the following examples for readability. See Also: Dialog API. Returns the number of times that the given substring was found within the string, starting the search at position. Warning: How to use Twine and SugarCube to create interactive adventure games Renders the message prefixed with the name of the macro and returns false. Only useful when you have an asynchronous callback that invokes code/content that needs to access story and/or temporary variables shadowed by <>. Twine Tutorials - Digital Ephemera All of the specified callbacks are invoked as the wrapper is invokedmeaning, with their this set to the this of the wrapper and with whatever parameters were passed to the wrapper. At most one case will execute. 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). This macro has been deprecated and should no longer be used. Twine1/Twee: Required. Returns the string with its first Unicode code point converted to upper case. This macro has been deprecated and should no longer be used. The def and ndef operators have very low precedence, so it is strongly recommended that if you mix them with other operators, that you wrap them in parenthesese.g., (def $style) and ($style is "girly"). See the _args special variable for its replacement. Returns how much remains of the playlist's total playtime in seconds, Infinity if it contains any streams, or NaN if no metadata exists. 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. This macro is functionally identical to <>, save that it uses a button element () rather than an anchor element (). Hides the loading screen, if no other locks exist. Once unloaded, playback cannot occur until the selected tracks' data is loaded again. API members dealing with the history work upon either the active momenti.e., presentor one of the history subsets: the full in-play historyi.e., past + futurethe past in-play subseti.e., past onlyor the extended past subseti.e., expired + past. Engine API. The active passage's tags will be added to its data-tags attribute (see: Passage Conversions). If you want to change the font or color, then you'll need to change the styling of the macro-type class. Or, if you use the start passage as real part of your story and allow the player to reenter it, rather than just as the initial landing/cover page, then you may wish to only disallow saving on the start passage the very first time it's displayedi.e., at story startup. SugarCube uses .ariaClick() internally to handle all of its various link markup and macros. In Twine, a variable is a way of storing and acting on data of some sort. Note: 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. A prototype-less generic object whose properties and values are defined by the Setting.addToggle(), Setting.addList(), and Setting.addRange() methods. Used to replace SugarCube's default UI. Opens the built-in settings dialog, which is populated from the Setting API. Terminates the execution of the current iteration of the current <> and begins execution of the next iteration. Circular references. Returns whether the track is currently unavailable for playback. Attaches event handlers to the selected tracks.
