This is a collection of tips, from how-tos to best practices. An alternative to navigating to passages to create menus, inventories, and the like would be to use the Dialog API. UI API. Local event triggered on the typing wrapper when the typing of a section starts. It is further strongly suggested that you provide that same custom user namespace when removing them. If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. Returns whether the UI bar is currently stowed. Warning: There is no one size fits all example for either of these methods because an instance's properties, and the data contained therein, are what determine what you need to do. Because of the additional HTML elements added by the debug views, some nested markup and selectors may be broken. There are two main presentation formats for Twine 2.0 texts: Harlowe and Sugarcube. Because the style markups use the same tokens to begin and end each markup, the same style cannot be nested within itself. An array is a container that holds things. 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. To affect multiple tracks and/or groups at once, see the SimpleAudio.select() method. Stops playback of the playlist and forces its tracks to drop any existing data. 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 an array of the story metadata store's key/value pairs as [key, value] arrays. Returns the seed from the seedable PRNG or, if the PRNG is not enabled, null. Note: Returns the processed text of the passage, created from applying nobr tag and image passage processing to its raw text. The predefined variable output, which is a reference to a local content buffer, is available for use within the macro's code contents. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. 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. Deprecated: Widgets allow you to create macros by using the standard macros and markup that you use normally within your story. Warning: Configurable, see Config.passages.start for more information. depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. Alias for jQuery, by default. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. Appends the given content to the dialog's content area. classes) guide for more detailed information. Concatenates one or more members to the end of the base array and returns the result as a new array. Warning: See Localization for more information. 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. Stops playback of all currently registered tracks and force them to drop any existing data. Note: Removes event handlers from the track. Instead, use the metadata property. The new l10nStrings object has a simpler, flatter, set of properties and better support for replacement strings. Doing so allows interactions with the text to also trigger its <>. For example: If you run the above, you'll see $x is 0. See Guide: Media Passages for more information. Note: Terminates the execution of the current <>. This method has been deprecated and should no longer be used. To enable test mode from the Stories screen, click on the story's gear menu and select the Test Play menu item. Warning: Returns the number of times that members within the array pass the test implemented by the given predicate function. Yes it is possible. Repeatedly executes its contents after the given delay, inserting any output into the passage in its place. 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. Returns a reference to the UIBar object for chaining. Attaches fullscreen error event handlers. SugarCube does not have any equivalents to Harlowe's (click:) family of macros. 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. Registers the passage as a VTT passage. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. Comments used within passage markup are not rendered into the page output. 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. Saving the story records the story's state up until the last moment that was created. If the autosave cannot be loaded, for any reason, then the start passage is loaded instead. Global event triggered as the last step in opening the dialog when Dialog.open() is called. If you need that kind of information from the dialog itself, then you may use the :dialogclosing event instead. Does not modify the original. 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. Yield the single line in the final output: An exclamation point (!) Tip: Opens the dialog. Deprecated: There are also "tags", which are basically arrays of values on a property of a bag or item. See Setting API for more information. Returns whether, at least, the track's metadata has been loaded. Begins playback of the track or, failing that, sets the track to begin playback as soon as the player has interacted with the document. If you want to set a title for display that contains code, markup, or macros, see the StoryDisplayTitle special passage. Thus, a call to UIBar.stow() may also be necessary. 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. Passage, tag, and variable names that have special meaning to SugarCube. Instead, call the UI.restart() static method, which prompts the player with an OK/Cancel dialog before itself calling Engine.restart(), if they accept. Randomly selects the given number of unique members from the base array and returns the selected members as a new array. See the State.prng.init() method for its replacement. Returns the Passage object referenced by the given title, or an empty Passage object on failure. Happens before the modification of the state history. 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. Generates no output. Shorthand for jQuery's .one() method applied to the audio element. Deprecated: Returns an AudioRunner instance for the tracks matching the given selector. Universal Inventory System (UInv) for Twine 2 / SugarCube 2 - GitHub - HiEv/UInv: Universal Inventory System (UInv) for Twine 2 / SugarCube 2. . Track event triggered when a fade completes normally. Note: In mobile browsers, playback volume is controlled by the device hardware. Returns whether a Passage object referenced by the given title exists. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. Note: When used to set the loop state, returns a reference to the current AudioTrack instance for chaining. See the :passagerender event for its replacement. Object that authors/developers may use to set up various bits of static data. Select "Change Story Format" and check the box next to "Sugarcube." Download PDF version: Variables and Programming in Twine The controls of the Settings dialog automatically call this method when settings are changed, so you should normally never need to call this method manually. Note: Note: String: The expression yields a string valuee.g.. Returns whether the track is currently unavailable for playback. Returns a random member from the array or array-like object. Returns a reference to the current AudioRunner instance for chaining. Returns whether the seedable PRNG has been enabled. Returns the bottommost (least recent) moment from the full in-play history (past + future). Note: Note: Functionally identical to <>. Sets the value of the story or temporary variable by the given name. Warning: However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). All other non-generic object types, on the other hand, must be made compatible to be successfully stored within story variables. Additionally, macros in SugarCube do not return values, so macros cannot be used as arguments to other macros. This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. This means that some code points may span multiple code unitse.g., the character is one code point, but two code units. The capitalization and punctuation used within the default replacement strings is deliberate, especially within the error and warning strings. If you need to check for multiple passages, the hasVisited() story function will likely be more convenient to use. True gapless transitions between tracks is not supported. May be terminated by a <> macro. For standard browser/DOM events, see the Event reference @MDN. This method has been deprecated and should no longer be used. Warning: This is not an exhaustive list. Passage start. Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. Begins playback of the playlist or, failing that, sets the playlist to begin playback as soon as the player has interacted with the document. The hierarchy of the document body, including associated HTML IDs and class names is as follows. 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). Returns the given string with all regular expression metacharacters escaped. Returns whether there are any filled slots. Concatenates one or more unique members to the end of the base array and returns the result as a new array. SimpleAudio API. In SugarCube, they come in two types: story variables and temporary variables. Returns a reference to the current AudioRunner instance for chaining. Many of the commonly used native non-generic object types are already fully compatible with and supported for use within story variablese.g., Array, Date, Map, and Set. Caches an audio track for use by the other audio macros. Outputs a string representation of the result of the given expression. Returns whether any of the target WAI-ARIA-compatible clickable element(s) are disabled. See Story API for more information. Returns whether the operation was successful. As with <> and <>, <> 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. No line-break control mechanisms are used in the following examples for readability. Data stored there won't take up space in the game history, but will be accessible both from Twine and . Assigns the value on the right-hand side of the operator to the left-hand side. See Tweego's documentation for more information. Instead, use Navigation Events or Tasks. The core menu item for the Settings dialog. Tip: To control aspects of your project based on the values contained within variables, see the <> and <> macros. Returns whether a fade is in-progress on the currently playing track. Examples of good uses: achievement tracking, new game+ data, playthrough statistics, etc. Valid values are the name of the property being animated, which causes the outgoing passage element to be removed once that transition animation is complete, or an integer delay (in milliseconds), which causes the outgoing passage element to be removed once the delay has expired. Dialog events allow the execution of JavaScript code at specific points during the opening and closing of dialogs. Prepends one or more members to the beginning of the base array and returns its new length. 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. Doing so allows interactions with the text to also trigger its <>. Returns the total number of filled slots. older versions of Twine2 used a icon for the same purpose. The story metadata store is not, and should not be used as, a replacement for saves. If you plan on using interactive macros within a loop you will likely need to use the. Does not modify the original. For example: Deprecated: NOTE: You do not call this manually, it must be called by the change event handler of an element. Periods of ellipsis () signify data that is generated at compile time. State.has() does not check expired moments. 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. Story API. Note: Warning: The array-like object stored in the _args variable should be treated as though it were immutablei.e., unable to be modifiedbecause in the future it will be made thus, so any attempt to modify it will cause an error. The :not() group modifier syntax (groupId:not(trackIdList)) allows a group to have some of its tracks excluded from selection. See Also: All these instructions are based on the SugarCube story format. When used to set the volume, returns a reference to the current AudioList instance for chaining. Note: This method has been deprecated and should no longer be used. Note: If multiple passage titles are given, returns the lowest count. This temporary playthrough session is intended to prevent players from losing data. To update the value associated with a key, simply set it again. Note: Note: Returns whether any valid sources were registered. See: Returns a pseudo-random decimal number (floating-point) in the range 0 (inclusive) up to, but not including, 1 (exclusive). Deprecated: Like in Harlowe, some SugarCube macros accept expressions and others accept discreet arguments. 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. Returns whether fullscreen is both supported and enabled. Renders and displays the passage referenced by the given title, optionally without adding a new moment to the history. Note: Additional elements, aside from the #passages element, may include either the data-init-passage or data-passage content attribute, whose value is the name of the passage used to populate the elementthe passage will be processed as normal, meaning that markup and macros will work as expected. To jump to any moment/turn within the available history, select the moment/turn from the Turn select field. Collects tracks, which must be set up via <>, into a playlist via its <> children. Opens the built-in jump to dialog, which is populated via the bookmark tag. Sets the selected tracks' volume level (default: 1). To delete all current watches, click the button. Sets the maximum number of states (moments) to which the history is allowed to grow. Warning: Removes classes from the selected element(s). Note: A fullscreen options object should have some of the following properties: Note: Causes any output generated within its body to be discarded, except for errors (which will be displayed). Note: Function templates should return a string, which may itself contain markup. Save API. SugarCube SugarCube is a free (gratis and libre) story format for Twine/Twee. classes) revival code and associated data within the revive wrapper, which should be returned from an object instance's .toJSON() method, so that the instance may be properly revived upon deserialization. Used within <> macros. This only affects test mode. Returns whether the history navigation was successful (should only fail if the index is not within the bounds of the full history). 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. Returns the current pull counti.e., how many requests have been madefrom the seedable PRNG or, if the PRNG is not enabled, NaN. 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. Creates a text input box, used to modify the value of the variable with the given name, optionally forwarding the player to another passage. Passage names have passage- prepended to their converted forms and are converted both into IDs and classes depending on how the passage is usedan ID for the active passage, classes for included (via <>) passages. Completely removes the UI bar and all of its associated styles and event handlers. Returns a new array consisting of all of the tags of the given passages. May be called either with the passage name and link text as separate arguments, with a link markup, or with a image markup. Harlowe's arrays, datamaps, and datasets are functionally similar to JavaScript Arrays, Maps, and Sets, but with a few key differences. Performs any required processing before the save data is loadede.g., upgrading out-of-date save data. The sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. The config API has been renamed Config for better consistency with the other APIs. Returns whether an audio track with the given track ID exists. Returns the title of the active (present) passage. See Dialog API for more information. Note: Returns how much remains of the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. SugarCube 2.x - The current version of SugarCube. Audio, image, video, and VTT passages are supported. Selects the element that contains passage elements. Moves backward one moment within the full history (past + future), if possible, activating and showing the moment moved to. Returns a reference to the UIBar object for chaining. The most interesting of which, from an end-user's standpoint, are 410. Returns the first of the macro's ancestors that passed the test implemented by the given filter function or null, if no members pass. Anyways, I wouldn't worry too much about maps or sets, but generic objects can be pretty useful, so I'd recommend understanding them. Returns whether any of the given members were found within the array. Note: Executes its contents and prepends the output to the contents of the selected element(s). See the Dialog API docs for more information. See the Macro API docs for more information. See the Setting API docs for more information. Gets or sets the track's repeating playback state (default: false). The SimpleAudio APIs use events internally for various pieces of functionality. The best example of an array is a pill container. Returns the current state of the engine ("idle", "playing", "rendering"). 3 4 4 comments Best Add a Comment ChapelR 4 yr. ago See <> for more information. The IFID (Interactive Fiction IDentifier) of the story, if any. The starting passage, the first passage displayed. prerender tasks have been deprecated and should no longer be used. The debug bar (bottom right corner of the page) allows you to: watch the values of story and temporary variables, toggle the debug views, and jump to any moment/turn within the history. Generates no output. In SugarCube, both variables would still point to the same underlying objectat least initially (see below): SugarCube does eventually clone its non-primitive data types as well, but does at the start of passage navigation, rather than each time they're modified. The HTML & CSS have undergone significant changes. 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. Story variables are a part of the story history and exist for the lifetime of a playthrough session. URL: https://cdn.jsdelivr.net/gh/tmedwards/sugarcube-2/dist/format.js. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. postdisplay tasks have been deprecated and should no longer be used. See Passage API for more information. The active passage's tags will be added to its data-tags attribute and classes (see: Passage Conversions). Requirements. The StoryInit special passage is normally the best place to set up groups.
