Aside from general syntax, SugarCube macros do not use hooks, separate arguments differently, and don't allow other macros to be passed as arguments. Determines whether outgoing passage transitions are enabled. All widgets may access arguments passed to them via the _args special variable. Generates no output. All these instructions are based on the SugarCube story format. Only deletes the group itself, does not affect its component tracks. The UISystem API object has been split into two APIs Dialog and UI, and some of its methods have also changed. The callback is invoked each time a save is requested. This does not alter the volume level. Outputs a string representation of the result of the given expression. Request that the browser exit fullscreen mode. 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. Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. For example: That probably won't be very pleasing to the eye, however, so you will likely need several styles to make something that looks half-decent. 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. 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. Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importScripts(). Warning: Returns the string with its first Unicode code point converted to upper case, according to any locale-specific rules. Assignment: The expression causes an assignment to occure.g., A backquote is also known as a grave and is often paired with the tilde (. Returns the playlist's current time in seconds, or NaN if no metadata exists. 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. Normally, when both link and text arguments are accepted, the order is text then link. When used to set a value, returns a reference to the current AudioTrack instance for chaining. Macro handlers are called with no arguments, but with their this set to a macro (execution) context object. Executes its contents while the given conditional expression evaluates to true. 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. Harlowe's implementation of the (goto:) macro terminates the rendering passage. As with <>, <> can accept link markup as its argument: SugarCube's user input macros, like <>, cannot be nested inside a <> macro, as you might do with a (prompt:) and a (set:) in Harlowe. Renders and displays the passage referenced by the given title, optionally without adding a new moment to the history. This method has been deprecated and should no longer be used. SugarCube SugarCube is a free (gratis and libre) story format for Twine/Twee. An options object should have some of the following properties: Changes the disabled state of the target WAI-ARIA-compatible clickable element(s). Returns whether a Passage object referenced by the given title exists. See Also: This setting has been deprecated and should no longer be used. 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. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. Some browsers, particularly mobile ones, will free up memory by unloading web pages that are running in the background. Does not modify the original. If its return value is falsy, the save is disallowed. . Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. Returns the number of passages within the story history that are tagged with all of the given tags. To enable test mode, use the test option (-t, --test). See Engine API for more information. The typed text has no default styling. This section offers a list of SugarCube-specific events, triggered at various points during story operation. Sugarcube Documentation http://www.motoslave.net/sugarcube/2/ Twine is a free online tool that allows you to create interactive stories like Choose Your Own Adventure books. A set of opening and closing tagsi.e., defines the verbatim HTML markup. Returns a reference to the current AudioRunner instance for chaining. Note: The sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. Testing is strongly advised. Randomly removes the given number of members from the base array and returns the removed members as a new array. Create a new passage, which will only be used as a media passageone per media source. Used to populate the story's menu items in the UI bar (element ID: menu-story). This is not an exhaustive list. Note: Returns a reference to the current AudioRunner instance for chaining. Subtracts the value on the right-hand side of the operator from the current value on the left-hand side and assigns the result to the left-hand side. This macro has been deprecated and should no longer be used. Divides the current value on the left-hand side of the operator by the value on the right-hand side and assigns the remainder to the left-hand side. Meaning that when you pass a variable as an argument, its value is passed to the macro rather than its name. Roughly equivalent to the :passagestart event. Note (Twine2): 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. Additional timed executions may be chained via <>. Harlowe's implementation of data types differs significantly from SugarCube's. Controls the playback of audio tracks, which must be set up via <>. IDs and classes automatically generated from passage names and tags are normalized to kebab case with all lowercase letterswhich entails: removing characters that are not alphanumerics, underscores, hyphens, en-/em-dashes, or whitespace, then replacing any remaining non-alphanumeric characters with hyphens, one per group, and finally converting the result to lowercase. 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. The core audio subsystem and backend for the audio macros. This macro is an alias for <>. State API. with 2.0. Load and integrate external JavaScript scripts. Generates no output. 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. In most cases, you will not need to use <> as there are often better and easier ways to forward the player. An asterisk (*) or number sign (#) that begins a line defines a member of the unordered or ordered list markup, respectively. TwineScript in SugarCube is, essentially, JavaScript with an extra spoonful of sugar on top to make it a bit nicer for the uninitiated. Twine2: Not special. When used to set the shuffle state, returns a reference to the current AudioList instance for chaining. 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. Upon a successful match, the matching case will have its contents executed. Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. If necessary, however, you may manually change their valuesn.b. Returns an array of the story metadata store's key/value pairs as [key, value] arrays. SugarCube is a free (gratis and libre) story format for Twine/Twee. Warning: Etc. State.prng.init() must be called during story initialization, within either your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or the StoryInit special passage. See Tweego's documentation for more information. Tip: Arrays have many built-in methods and other features, and SugarCube adds many more. Returns the array of track IDs with the given group ID, or null on failure. 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. Returns an array of the story metadata store's keys. Determines whether alternate passage descriptions are used by the Saves and Jump To menusby default an excerpt from the passage is used. Wikifies the given content source(s) and appends the result to the target element(s). Returns the total number (count) of played turns currently in effecti.e., the number of played moments up to the present moment; future (rewound/undone) moments are not included within the total. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). LoadScreen API. Deprecated: Returns the number of times that the passage with the given title occurred within the story history. Warning: Returns whether the seedable PRNG has been enabled. Strings are iterated by Unicode code point, however, due to historic reasons they are comprised of, and indexed by, individual UTF-16 code units. See Also: Returns the AudioTrack instance with the given track ID, or null on failure. Normally, there will be only one such passage per turn, however, during passage navigation there may briefly be twothe incoming (a.k.a. Multiplies the current value on the left-hand side of the operator by the value on the right-hand side and assigns the result to the left-hand side. Note: In Harlowe, the same operation will yield an error: You must convert the values to the same type in Harlowe. Next, the StoryInit special passage is processed. It is further strongly suggested that you provide that same custom user namespace when removing them. May be called either with a list of passages, with a list of link markup, or with a list of image markup. See the Dialog API and UI API docs for more information. Config.saves.autosave setting, Config.saves.autoload setting, and Save API: Autosave. 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. Those that do not bundle SugarCube v2: Only the older Twine2.0 series. Note: A macro definition object should have some of the following properties (only handler is absolutely required): Additional properties may be added for internal use. There are several beginner's guides on the web to using Sugarcube . If your content consists of DOM nodes, you'll need to use the Dialog.append() method instead. Probably most useful when paired with <>. Gets or sets the mute-on-hidden state for the master volume (default: false). There are several configuration settings for saves that it would be wise for you to familiarize yourself with. No other characters are allowed. 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. This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. Returns the total number of available slots. The story title is used to create the storage ID that is used to store all player data, both temporary and persistent. Tag it with the appropriate media passage special tag, and only that tagsee below. For example: (not an exhaustive list). Note: Returns the last member from the array. The seed is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. Sets the maximum number of states (moments) to which the history is allowed to grow. It is passed an abbreviated version of the associated passage's Passage instancecontaining only the tags, text, and title properties. Note: 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. Attempting to do so will, usually, result in something that's non-functional. Returns a reference to the current AudioTrack instance for chaining. NOTE: This should not be confused with story variables, which start with a $e.g., $foo. 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. Triggered before the rendering of the incoming passage. 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. Furthermore, it is no longer instantiated into the legacy macros objectwhich still exists, so SugarCube-compatible legacy macros will continue to work. Returns whether the full in-play history (past + future) is empty. Returns a reference to the UIBar object for chaining. NOTE: You do not call this manually, it must be called by the change event handler of an
