See LoadScreen API for more information. Returns the whole (integer) part of the given number by removing its fractional part, if any. Returns a reference to the active (present) story variables store (equivalent to: State.variables). Sugarcube is a legacy version that supports the features and syntax of earlier Twine 1.x versions. Returns the moment, relative to the bottom of the past in-play history (past only), at the given index. Function behavior is immutable. 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. Returns an AudioRunner instance for the tracks matching the given selector. Returns whether the dialog is currently open. Returns the number of currently registered on-load handlers. Adds a playlist with the given list ID. Returns whether the named template exists. 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. UI API. prehistory tasks have been deprecated and should no longer be used. 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 any moments with the given title exist within the past in-play history (past only). Widget arguments array (only inside widgets). Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. Alias for jQuery, by default. The number of moments contained within the story history is, generally, limited, via the Config.history.maxStates setting. To avoid this problem, it's suggested that you use the separate argument form of the < > macro in Twine2as shown above. This method has been deprecated and should no longer be used. 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. A Twine 2 proofing format that renders nodes as a GraphViz (dot) graph. Audio lists (playlists) are useful for playing tracks in a sequencei.e., one after another. an array holding the names of the days of the week) on a story variable, it should be stored on the SugarCube setup object variable instead. postdisplay tasks have been deprecated and should no longer be used. Copy the following URL and paste it into the Add a New Format tab of the Formats menu, from Twine2's sidebar. Returns the last Unicode code point within the string. This macro has been deprecated and should no longer be used. Template API. The starting passage, the first passage displayed. Normally, those aren't issues as you should not need to use the result of an expression as an argument terribly often. Sets the default KeyboardEvent.key value that causes the currently running <> macro instance to finish typing its content immediately. The story's title is part of the story project. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. A range definition object should have some of the following properties: Note: See the :passagerender event for its replacement.

It can be loaded manually by the player or automatically by the autoload feature, which can be configured to, upon start up, either load the autosave automatically or prompt the player about loading it. The pull count is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. See: See Also: Creates a number input box, used to modify the value of the variable with the given name, optionally forwarding the player to another passage. Note: Harlowe has stricter typing than SugarCube, requiring authors to call macros like (str:) or (num:) on variables to change their type. Tag it with the appropriate media passage special tag, and only that tagsee below. There are many ways to use and interact with variables. This macro should be invoked once following any invocations of <> and <>, if any <> definitions used the copy keyword, for which you want the loading screen displayed. The debug views may be toggled via the Views button. Returns the title of the active (present) passage. Note: Returns a reference to the current AudioTrack instance for chaining. Gets or sets the playlist's volume level (default: 1). Note: The autosave is, for the most part, a normal save slot, but with a few special features built in. Stops playback of the selected tracks and forces them to drop any existing data. Returns whether playback of the playlist has ended. In most cases, you will not need to use <> as there are often better and easier ways to forward the player. Prepends one or more unique members to the beginning of the base array and returns its new length. See Also: Global event triggered once just before the page is reloaded when Engine.restart() is called. For game-oriented projects, as opposed to more story-oriented interactive fiction, a setting of 1 is strongly recommended. Each link removes itself and all other <> links to the same passage after being activated. Warning: When used to set a value, returns a reference to the current AudioTrack instance for chaining. See Dialog API for more information. Returns the number of moments within the past in-play history (past only). Returns a reference to the current jQuery object for chaining. Terminates the execution of the current <>. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. The config API has been renamed Config for better consistency with the other APIs. Does not modify the original. 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. Note (Twine2): Events are messages that are sent (a.k.a. Returns the AudioList instance with the given list ID, or null on failure. If its return value is falsy, the save is disallowed. At most one case will execute. Warning: Macro API. See the <> macro for its replacement. Deprecated: Triggered before the modification of the state history. Note: 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. Instance methods of classes are not affected by either issue, as they're never actually stored within story variables, being referenced from their classes' prototypes instead. It is not a mechanism for moving data between stories. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. 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. Opens the built-in share dialog, which is populated from the StoryShare passage. Possible reasons include: no valid sources are registered, no sources are currently loaded, an error has occurred. Returns whether all of the given members were found within the array. The story metadata store is not, and should not be used as, a replacement for saves. When used to set the mute state, returns a reference to the current AudioList instance for chaining. Note: Request that the browser toggle fullscreen modei.e., enter or exit as appropriate. All these instructions are based on the SugarCube story format. Returns whether the history navigation was successful (should only fail if the offset from the active (present) moment is not within the bounds of the full history).

See the .flat() method for its replacement. Warning: However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). Requirements. Go to your Twine1/Twee installation directory and open the. Returns a reference to the dialog's content area. 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. SimpleAudio API, AudioTrack API, and AudioRunner API. Essentially, a combination of < > and <>.

If you wish to use custom backgrounds, either simply colors or with images, then you should place them on the body element. Returns the first member from the array. Returns the bottommost (least recent) moment from the full in-play history (past + future). To jump to any moment/turn within the available history, select the moment/turn from the Turn select field. Macro handlers are called with no arguments, but with their this set to a macro (execution) context object. 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, <>, <>. Displays the loading screen until all currently registered audio has either loaded to a playable state or aborted loading due to errors. This is only really useful when you want to invoke a macro for its side-effects and aren't interested in its output. All properties of Passage objects should be treated as if they were read-only, as modifying them could result in unexpected behavior. Not everyone has Deprecated: If you want to play tracks in a sequence, then you want a playlist instead. Warning: Only useful when you have an asynchronous callback that invokes code/content that needs to access story and/or temporary variables shadowed by <>. <> does not terminate passage rendering in the passage where it was encountered, so care must be taken to ensure that no unwanted state modifications occur after its call. A list definition object should have some of the following properties: Adds the named property to the settings object and a range control for it to the Settings dialog. May be terminated by a <> macro. Returns a reference to the Dialog object for chaining. In my version of Twine, the dialog box looks like this: In this dialog box, select the SugarCube alternative with the latest version number (SugarCube 2.x.x, the higher the numbers the better). See: Arrays have many built-in methods and other features, and SugarCube adds many more. The handler is passed one parameter, the save object to be processed. Generally, only really useful for formatting blocks of macros for ease of use/readability, while ensuring that no output is generated, from spacing or whatnot. Does not modify the original. To update the value associated with a key, simply set it again. Note: Sets the selected tracks' volume mute state (default: false). The DOM macros do have a limitation that you should familiarize yourself with. Returns a reference to the current jQuery object for chaining. Does not modify the original. Create a new passage, which will only be used as a media passageone per media source. Returns whether the slot saves are available and ready. Sets the starting passage, the very first passage that will be displayed. Indicates whether SugarCube is running in test mode, which enables debug views. Immediately forwards the player to the passage with the given name. The history allows players to navigate through these moments. Using <> to automatically forward players from one passage to another with no input from them will both create junk moments within the story history and make it extremely difficult for players to navigate the history. The parser instance that generated the macro call. SimpleAudio API. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. Warning: Returns a new array consisting of the flattened source array. Selects all internal link elements within the passage elemente.g., passage and macro links. If you click the link that sets the variable to 2, and then save the story, the $var variable will still be saved as 1, because a new moment has not yet been created. . Warning: See the HTML and CSS docs for more information. This method has been deprecated and should no longer be used. See the State.prng.init() method for its replacement. AudioTrack API, AudioRunner API, and AudioList API. Requires tracks to be set up via <>. . The best example of an array is a pill container. If its return value is truthy, the override succeeds and that value is used as the new destination of the navigation. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. Note: True gapless transitions between tracks is not supported. Wikifies the given content source(s) and appends the result to the target element(s). Attaches single-use event handlers to the selected tracks. Used within <> macros. Happens after the rendering of the incoming passage. Registers the passage as <> macro definitions, which are loaded during startup. For example: Deprecated: .on() in the jQuery API docs for more information. In SugarCube, the passage is not terminated, and anything in the code below the <> macro will have side effects. Temporary variables were added in v2.3.0. Deprecated: Does not modify the original. This property is automatically set based on whether you're using a testing mode in a Twine compileri.e., Test mode in Twine2, Test Play From Here in Twine1, or the test mode option (-t, --test) in Tweego. Unfortunately, this means that the two objects are incompatible. This only affects test mode. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. This is a collection of tips, from how-tos to best practices. Note: The Share dialog only displays linksspecifically, anything that creates an anchor element (). 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. Paste in the Base64-encoded media source as the passage's content. Returns the given number clamped to the specified bounds. Adds an audio group with the given group ID. A variable is a bit of storage where you may stash a value for later use. Next, the StoryInit special passage is processed. If you limit the moments within the history to 1, via setting Config.history.maxStates to 1, then there will only ever be one moment in the history, but passage navigation is still required for new moments to be created. To delete a watch, click the button next to its name in the watch panel. .one() in the jQuery API docs for more information. Deprecated: 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. classes) guide for more detailed information. 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. Removes all of the members at the given indices from the array and returns a new array containing the removed members. Manages the Settings dialog and settings object. Warning: Returns the save object from the autosave or null, if there was no autosave. Expressions are simply units of code that yield values when evaluated. Several UI API methods have moved to the new Dialog API. There's no way for the system to know ahead of time whether it's safe to re-execute a passage's contents. Returns whether enough data has been loaded to play the track through to the end without interruption. Furthermore, it is no longer instantiated into the legacy macros objectwhich still exists, so SugarCube-compatible legacy macros will continue to work. Dialog API. 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. URL: https://cdn.jsdelivr.net/gh/tmedwards/sugarcube-2/dist/format.js. If multiple passage titles are given, returns the lowest count. Note: Removes fullscreen change event handlers. Note: 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. Caveat for Internet Explorer: SugarCube only supports IE 9. Used to replace SugarCube's default UI. May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. See Localization for more information. Returns the number of passages within the story history that are tagged with all of the given tags. Warning: To modify the values contained within variables, see the <> macro and setter links. Any supported object type may itself contain any supported primitive or object type. Returns a reference to the current AudioRunner instance for chaining. Returns whether there are any filled slots. Returns the array of track IDs with the given group ID, or null on failure. This section offers a list of SugarCube-specific events, triggered at various points during story operation. 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. Testing whether an array contains an element can be done using the Array#includes() function; adding new items can be done using the Array#push() function. Used to populate the authorial byline area in the UI bar (element ID: story-author). 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. Temporary variables do not become part of the story history and only exist for the lifetime of the moment/turn that they're created in. The History API object has been renamed to State and some of its methods have also changed. Roughly equivalent to the :passagerender event. The default cursor is the block element character Right Half Block (U+2590) and it has no default font or color styling. In both cases, since the end goal is roughly the same, this means creating a new instance of the base object type and populating it with clones of the original instance's data. Returns a random member from the array or array-like object. Note: blazing fast internet with unlimited dataespecially true for mobile users. This method has been deprecated and should no longer be used. The seed is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. Both of these features can be constructed in SugarCube, however, using macros like <> or by combining < > macros with DOM macros. Note: See the <> macro for its replacement. Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restarts. This means, however, that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. See the Save.onLoad.add() method for its replacement. It would probably help if you were more specific as to your goal. Does not modify the original. Appends the given content to the dialog's content area. SugarCube SugarCube is a free (gratis and libre) story format for Twine/Twee. Note: Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Compilers supporting automatic creation of media passages: Warning (Twine2): To enable test mode from the story editor/map screen, click on the Test menu item (right side of the bottom bar). prerender tasks have been deprecated and should no longer be used. Note: Only when manually modifying the values of settings object properties, outside of the controls, would you need to call this method. Note: A sort of simple Twine parser. All user functions and macros that check for the existence of moments within the history check both the story history and expired moments, so will work as expected even if the history is limited to a single moment as described above. Return the named template definition, or null on failure. Removes and returns a random member from the base array. You must, generally, use them with an interactive macroe.g., < > macrothe <> macro, or within the PassageDone special passage. Note: Loss of visibility is defined as when the browser window is either switched to another tab or minimized. Each event is represented by an object that has properties that may be used to get additional information about what happened. If you need to check for multiple passages, the hasVisited() story function will likely be more convenient to use. This method has been deprecated and should no longer be used. However, I've tried to use elements in these arrays, like this: $y=$z [0] [2] and it doesn't seem to work. Returns a timestamp representing the last time Engine.play() was called. Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. (Help) Error: UI is not defined when trying to create a save/load button SugarCube 2 Hi, i'm pretty new to using twine / sugarcube, so i do apologise for the noob question.

String values will still be accepted for further releases of v2, however, switching to an array is recommendede.g., the string value, This method has been deprecated and should no longer be used. SugarCube provides a variety of functions and methods that may be used instead, and standard JavaScript functions and methods may also be used. Note: Added to the active passage's container element, Added to the active passage's container element and. Returns the value associated with the specified key from the story metadata store or, if no such key exists, the specified default value, if any. Generates no output. If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. Saving the story records the story's state up until the last moment that was created. The variable watch panel may be toggled via the Watch button. Generates no output. Zorkish Sugarcube 6. Returns the AudioTrack instance with the given track ID, or null on failure. The exactly equivalent call is: .flat(Infinity). An array of strings, which causes the autosave to be updated for each passage with at least one matching tag. Warning: 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. Click the Formats button in the right sidebar of Twine. 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. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions.
