SugarCube requires authors to define and work with these data types using the standard JavaScript methods rather than providing macros for them. Returns a reference to the current jQuery object for chaining. In particular, the parameter list for the Dialog.setup() method has changed. Request that the browser toggle fullscreen modei.e., enter or exit as appropriate. A set of opening and closing tagsi.e., defines the verbatim HTML markup. Returns an array of the story metadata store's keys. Warning: 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. Returns whether the slot saves are available and ready. Warning: Outputs a string representation of the result of the given expression. We'll cover some of these differences below. Removes the specified key, and its associated value, from the story metadata store. A format item has the syntax {index[,alignment]}, square-brackets denoting optional elements. Deprecated: If you have a property that uses an array of values, you will be able to use the various "tag" functions to . 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. The starting passage, the first passage displayed. For example, let's return to the example above and change it again: You'll see that setup.y is being set to 1 and displayed properly regardless of whether you load a saved story or not, because it is not part of the state. Note: Passage start. Cannot delete tracks solely under the control of a playlist. You can use custom style markup or HTML to create the elements, and then target them with a query selector. May be called either with the passage name or with a link markup. The argument string after converting all TwineScript syntax elements into their native JavaScript counterparts. To pass expressions or the results of functions to macros as an argument, you must wrap the expression in backquotes (`). A text replacement markup. Deprecated: An array of discrete arguments parsed from the argument string. Begins playback of the playlist or, failing that, sets the playlist to begin playback as soon as the player has interacted with the document. Attaches single-use event handlers to the track. Returns the total number of available slots. Audio tracks encapsulate and provide a consistent interface to an audio resource. Call this only after populating the dialog with content. Returns the number of times that members within the array pass the test implemented by the given predicate function. Appends one or more unique members to the end of the base array and returns its new length. See Passage API for more information. Etc. Instead, use either the built-in functions random() & randomFloat() or the State.random() method, if you need direct access to the PRNGsince it returns a call to either Math.random() or the seedable PRNG, as appropriate. Indicates whether SugarCube is running in test mode, which enables debug views. That will only toggles the views, test mode must still be enabled first. Does not modify the original. Returns a random member from the base array. This means that some code points may span multiple code unitse.g., the character is one code point, but two code units. Returns whether any valid sources were registered. Note: For example, the following is the data URI of a Base64-encoded PNG image of a red dot (): Generally, it's expected that you will use a compiler that supports the automatic creation of media passages, however, they may be created manually. Additional timed executions may be chained via <
>. Requires tracks to be set up via <>. To add a watch for a variable, type its name into the Add field and then either press enter/return or click the buttonn.b. Outputs a string representation of the result of the given expression. Shorthand for jQuery's .one() method applied to each of the audio elements. Returns whether a fade is in-progress on the currently playing track. Does not modify the original. For example: In general, you can group expressions into categories based on what kind of value they yield and/or what side effects they cause. Note: Does not modify the original. All properties of Passage objects should be treated as if they were read-only, as modifying them could result in unexpected behavior. All these instructions are based on the SugarCube story format. This method has been deprecated and should no longer be used. See UIBar API for more information. There are two main presentation formats for Twine 2.0 texts: Harlowe and Sugarcube. For . The new l10nStrings object has a simpler, flatter, set of properties and better support for replacement strings. Logical: The expression yields a boolean valuee.g.. Loop variables are perfect candidates for the use of temporary variablese.g.. To ensure that line-breaks end up where you want them, or not, extra care may be required. Twine1/Twee: Registers the passage as JavaScript code, which is executed during startup. State.top is not a synonym for State.active. Furthermore, it is no longer instantiated into the legacy state objectwhich still exists, so legacy code will continue to work. All DOM macros require the elements to be manipulated to be on the page. Note: Used to populate the authorial byline area in the UI bar (element ID: story-author). This is only really useful within pure JavaScript code, as within TwineScript you may simply access story variables natively. . An alternative to navigating to passages to create menus, inventories, and the like would be to use the Dialog API. For example: See: 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(). To enable test mode while starting at a specific passage, right-click on a passage and select the Test Play From Here context menu item. Sets the maximum number of iterations allowed before the <> macro conditional forms are terminated with an error. Returns whether all of the given members were found within the array. Returns the value associated with the specified key from the story metadata store. 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. You may, however, forcibly enable it if you need to for some reasone.g., if you're using another compiler, which doesn't offer a way to enable test mode. Deprecated: The default font stack is set here. Returns the AudioTrack instance with the given track ID, or null on failure. Used to populate the contents of the Share dialog. Returns a reference to the current AudioRunner instance for chaining. Similarly, if the directory is sugarcube-2, then the name of the .py file within must be sugarcube-2.py. Probably most useful when paired with <>. For standard browser/DOM events, see the Event reference @MDN. 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. Note: Returns an AudioRunner instance for the tracks matching the given selector. Returns a reference to the Dialog object for chaining. Does not affect script or stylesheet tagged passages, for Twine1/Twee, or the Story JavaScript or Story Stylesheet sections, for Twine2. If you want to change the font, color, or character, then you'll need to change the styling of the :after pseudo-element of the macro-type-cursor class. 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. Once unloaded, playback cannot occur until the selected tracks' data is loaded again. Donate Release Notes for v2 SugarCube v2.36.1 ( 2021-12-21) Fixed an issue with the build system that was producing subtly broken builds. Additionally, macros in SugarCube do not return values, so macros cannot be used as arguments to other macros. If you should chose to use an explicit seed, however, it is strongly recommended that you also enable additional entropy, otherwise all playthroughs for all players will be exactly the same. Returns a new array consisting of all of the tags of the given passages. Stops playback of the playlist and forces its tracks to drop any existing data. Deprecated: Twine1/Twee: Required. Circular references. Determines whether outgoing passage transitions are enabled. If the autosave cannot be loaded, for any reason, then the start passage is loaded instead. Load and integrate external JavaScript scripts. The API automatically calls this method at startup, so you should never need to call this method manually. Anything from a number to a series of characters can be stored in a variable. 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. While not specifically about SugarCube, the About Expressions section of the Twine1 reference documentation may also be helpful. Prepends one or more unique members to the beginning of the base array and returns its new length. <> macro events allow the execution of JavaScript code at specific points during typing. If you don't know what that means, then this API is likely not for you. Does not modify the original. Note: Thus, if you allow players to return to passages, then you should either: ensure the passages contain no code that has side-effects or wrap that code in something to prevent re-executione.g., <>side-effects< >. Removes and returns the last member from the array, or undefined if the array is empty. Do not add a widget tag to any of the specially named passages and attempt to define your widgets there. June 2017 in Help! 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. The body of the page. 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. Does not modify the original. Widgets allow you to create macros by using the standard macros and markup that you use normally within your story. 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. Returns the AudioList instance with the given list ID, or null on failure. Prepares the dialog for use and returns a reference to its content area. A decision I made was that all the individual strings in the array will also match the object's passage names. Returns a new array filled with all Passage objects that contain the given property, whose value matches the given search value, or an empty array, if no matches are made. 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. 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 sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. 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. SugarCube, like JavaScript, uses dynamic typing. This is chiefly intended for use by add-ons/libraries. Determines whether saving is allowed within the current context. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. 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). There are several configuration settings for saves that it would be wise for you to familiarize yourself with. Note: Returns the moment, relative to the bottom of the past in-play history (past only), at the given index. Warning: Attaches event handlers to the selected tracks. 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. Warning (Twine 2): Due to how the Twine . Note: Note: This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. An options object should have some of the following properties: Changes the disabled state of the target WAI-ARIA-compatible clickable element(s). 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. Returns a reference to the UIBar object for chaining. Shows the UI bar. Creates a listbox, used to modify the value of the variable with the given name. This method has been deprecated and should no longer be used. Note: The config object has been renamed to Config and some of its properties have also changed. Happens after the rendering of the incoming passage. If your content contains any SugarCube markup, you'll need to use the Dialog.wiki() method instead. This functionally refreshes the webpage, and can cause users to lose their progress. This does not reclaim the space reserved for the UI bar. Deletes the specified on-save handler, returning true if the handler existed or false if not. Shorthand for jQuery's .off() method applied to the audio element. that begins a line defines the heading markup. Navigating back to a previous passage, for whatever reason, can be problematic. There's no way for the system to know ahead of time whether it's safe to re-execute a passage's contents. SimpleAudio API, AudioTrack API, and AudioList API. SimpleAudio API. An array is a list of different words or text, referred to as strings in this blog post. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). Request that the browser enter fullscreen mode. When using Twine1/Twee, it is strongly recommended that you use only a single stylesheet tagged passage. Those that want an expression are fairly straightforward, as you simply supply an expression. SugarCube Snowman Twine 2 Examples Twine 2 Examples . Returns whether the track is currently unavailable for playback. In general, look to the, Replaced the ungainly link text syntax, The various Options macros have been removed. Returns how much remains of the playlist's total playtime in seconds, Infinity if it contains any streams, or NaN if no metadata exists. Repeatedly executes its contents. Twine 2: User Input in SugarCube Twine 2: Using Images in SugarCube Twine 2: Using Functions as Macros in Snowman Twine 2: Creating a Dungeon Crawler Part 1 Twine 2: Creating a Dungeon Crawler Part 2 Twine 2: Creating a Dating Sim Twine 2: Re-creating Candy Box Twine 2: Inventory Systems Twine 2: Murder Hill House Mystery Part 1 The affected elements are the story: banner, subtitle, author, caption, and menu. Returns the number of moments within the past in-play history (past only). NOTE: You do not call this manually, it must be called by the change event handler of an element. Object that authors/developers may use to set up various bits of static data. Appends one or more members to the end of the base array and returns its new length. May be terminated by a <> macro. Adds an audio group with the given group ID. Returns a random value from its given arguments. SugarCube 1.x - The legacy version . Local event triggered on the typing wrapper when the typing of a section starts. Returns the number of passages within the story history that are tagged with all of the given tags. Returns a save object from the given slot or null, if there was no save in the given slot. Returns whether an audio track with the given track ID exists. Does not modify the original. Function templates should return a string, which may itself contain markup. The handler is passed one parameter, the save object to be processed. Note: Identical to calling .map().flat(). A range definition object should have some of the following properties: Note: Due to how SugarCube stores the state history a few constructs are not supported within story variables. It is further strongly suggested that you provide that same custom user namespace when removing them. If the condition evaluates to false and an <> or <> exists, then other contents can be executed. Note: Sets the selected tracks' repeating playback state (default: false). Returns a reference to the current AudioTrack instance for chaining. Creates a text input box, used to modify the value of the variable with the given name, optionally forwarding the player to another passage. Tip: Once unloaded, playback cannot occur until the track's data is loaded again. Roughly equivalent to the :passagerender event. Executes its contents and replaces the contents of the selected element(s) with the output. Executes its contents if the given conditional expression evaluates to true. Starts playback of the track and fades it between the specified starting and destination volume levels over the specified number of seconds. State.current is not a synonym for State.active. The core menu item for the Settings dialog. 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. Harlowe's arrays, datamaps, and datasets are functionally similar to JavaScript Arrays, Maps, and Sets, but with a few key differences. The IFID (Interactive Fiction IDentifier) of the story, if any. For example, if you wanted to ask the user to enter a name, your code may look like this in Harlowe: In SugarCube, you would likely want to use the <> macro instead, and pass $name in as the receiving variable: Harlowe's newer input macros, like (dropdown:) and (cycling-link:) use "bound" variables, which are similar in concept to SugarCube's receiver variables. A side effect simply means that the evaluation of the expression modifies some state. : fired, triggered) to notify code that something has taken place, from player interactions to automated happenings. Passing the result of an expression as an argument is problematic for a couple of reasons: because the macro argument parser doesn't treat arguments as expressions by default and because it separates arguments with whitespace. May be called with, optional, link text or with a link or image markup. See Also: Returns the seed from the seedable PRNG or, if the PRNG is not enabled, null. SimpleAudio API, AudioTrack API, and AudioRunner API. See the :passagestart event for its replacement. Returns whether a fade is in-progress on the track. The following types of values are natively supported by SugarCube and may be safely used within story and temporary variables. Returns whether enough data has been loaded to play the track through to the end without interruption. Sets the selected tracks' current time in seconds. Starts playback of the playlist and fades the currently playing track between the specified starting and destination volume levels over the specified number of seconds. sugarcube-2: macros: customMacroName: container: true anotherOne: {} If using *.twee-config . Global event triggered as the last step in closing the dialog when Dialog.close() is called. Triggered after the displayi.e., outputof the incoming passage. Outputs a string representation of the result of the given expression. The names of both story and temporary variables have a certain format that they must followwhich signifies that they are variables and not some other kind of data. Note: classes) guide for more information. Opens the built-in restart dialog, prompting the player to restart the story. Note: When a widget is called, any existing _args variable, and for container widgets _contents, is stored for the duration of the call and restored after. I've done it like this: $z= [ [1,2,3], [1,2,1], [4,4,0]] and it doesn't generate an error. See the <> macro for its replacement. See the. This only affects test mode. Interactions with macros or other code that inject content only after some external action or periode.g., <>, <>, etc.may or may not behave as you'd expect. Returns the current moment from the full in-play history (past + future), which is the pre-play version of the active moment. Now, load the saved story from before the changes were made, and you'll see $y is undefined, since it doesn't exist at all in the loaded state. The $args special variable has been deprecated and should no longer be used. If you're simply looking to download ready-to-use localizations, see SugarCube's website (under Downloads > Localizations). To print the values contained within variables, see the naked variable markup and the <>, <<=>>, and <<->> macros. Note: Widget contents string (only inside block widgets). Stops playback of all currently registered tracks and force them to drop any existing data. The template markup begins with a question mark (?) 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. See State API for more information. Passing the name of a variable as an argument is problematic because variable substitution occurs automatically in SugarCube macros. Gets or sets the master volume level (default: 1). Sets the maximum number of states (moments) to which the history is allowed to grow. UI API. The document element. It is strongly recommended that you use only one stylesheet passage. Warning: This method will not detect "code" passagesi.e., script, stylesheet, and widget passages. If you're on Linux, right-click on the file and select Copy. Data stored there won't take up space in the game history, but will be accessible both from Twine and . 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. Prior to SugarCube v2.10.0, the strings localization object was named strings. Whenever your story is first started or, for any reason, restartede.g., the browser window/tab was refreshed/reloadedit undergoes its startup sequence. Returns whether the autosave is available and ready. 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. It must contain, at least, an element with the ID passages that will be the main passage display area. See Story API for more information. 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. Determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). Moves backward one moment within the full history (past + future), if possible, activating and showing the moment moved to. This is a reference for localizing SugarCube's default UI text, in general, and its l10nStrings object specifically. depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. Note: Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . Template API. The DOM macros do have a limitation that you should familiarize yourself with. Returns the given number clamped to the specified bounds. Immediately forwards the player to the passage with the given name. When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. See Also: If no conditional expression is given, it is equivalent to specifying true. Sets the starting passage, the very first passage that will be displayed. If omitted, the story title will be used instead. Valid values are boolean true, which simply causes the autosave to be loaded, the string "prompt", which prompts the player via a dialog to load the autosave, or a function, which causes the autosave to be loaded if its return value is truthy. [SugarCube 2.21.0] Two-dimensional arrays. Use the Edit Story JavaScript story editor menu item for scripts. 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. Begins playback of the selected tracks or, failing that, sets the tracks to begin playback as soon as the player has interacted with the document. Note: The Fullscreen API comes with some built-in limitations: Returns the current fullscreen element or, if fullscreen mode is not active, null. 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. Returns the last Unicode code point within the string. Allows custom processing of passage text. Determines whether certain elements within the UI bar are updated when passages are displayed. 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. This method is meant to work with clickables created via .ariaClick() and may not work with clickables from other sources. Roughly equivalent to the :passagestart event. By convention, properties starting with an underscoree.g., _warningIntroLackingare used as templates, only being included within other localized strings. 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. This setting exists because it's unlikely that you'll ever want to actually perform an assignment within a conditional expression and typing = when you meant === (or ==) is a fairly easy to mistake makeeither from a finger slip or because you just don't know the difference between the operators. 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. To actually affect multiple tracks and/or groups, see the SimpleAudio.select() method. In these cases, audio will not automatically play on the starting passage, nor is it likely to play if initiated from within asynchronous codee.g., via. Normally, the values of its properties are automatically managed by their associated Settings dialog control. Deprecated: 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. .off() in the jQuery API docs for more information. When setting the value to boolean true, you will likely also need to use the Config.saves.isAllowed property to disallow saving on the start passage. In SugarCube, the passage is not terminated, and anything in the code below the <> macro will have side effects. Note: The function will be called just before the built-in no-break passage processing if you're also using thatsee the Config.passages.nobr setting and nobr special tag. Additionally. 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. In Twine, return to your project library by clicking the house icon in the lower-left corner of the Twine window. Warning: Go to your Twine1/Twee installation directory and open the. Sylen. Fullscreen API. Instead, the macro is passed a receiver variable which is set to the value input by the user. Attaches fullscreen error event handlers. When used to set the shuffle state, returns a reference to the current AudioList instance for chaining. UI bar special passages update. Note: Essentially, a combination of < > and <>. Deprecated: If you only need to print the value of a TwineScript variable, then you may simply include it in your normal passage text and it will be printed automatically via the naked variable markup. Caveat for Internet Explorer: SugarCube only supports IE 9. Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. See the .includesAll() method for its replacement. You can see this effect by changing data outside the state. Passage navigation terminates all pending timed executions. Additionally, SugarCube's link macro accepts a passage argument, that, if included, turns any < > into something similar to Harlowe's (link-goto:) macro. A sort of simple Twine parser. May be called either with the passage name or with a link markup.
