The body of the page. As with all special tags, media passage tags are case sensitive, so their spelling and capitalization must be exactly as shown. classes) guide for more information. This allows you to fine tune for those cases. See Also: The State.display() methodformerly state.display()is no longer overridable, meaning it cannot be wrappede.g., the "StoryRegions" 3rd-party add-ons do this. that begins a line defines the heading markup. Triggered before the rendering of the incoming passage. 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. Controls the playback of audio tracks, which must be set up via <>. For normal projects, authors are encouraged to continue to use the StoryInit special named passage. Pease, do not take your players' bandwidth and data usage lightly. See Fullscreen API for more information. Returns whether a fade is in-progress on the currently playing track. Unused by SugarCube. Warning: Returns the string with its first Unicode code point converted to upper case. Opens the built-in jump to dialog, which is populated via the bookmark tag. See: Note: This does not reclaim the space reserved for the UI bar. These instances will be noted. Upon a successful match, the matching case will have its contents executed. An array is just like a pill container except it can only contain one item. Determines whether saving is allowed within the current context. Executes its contents if the given conditional expression evaluates to true. Deprecated: 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. Generates no output. You must, generally, use them with an interactive macroe.g., <> macrothe <> macro, or within the PassageDone special passage. Circular references. The predefined variable output, which is a reference to a local content buffer, is available for use within the macro's code contents. Note: SugarCube features a configurable autosave system. 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. SugarCube v2.36. Sets the story's title. Making a new story To make a new story, press the button labelled + Story. See the forget() function for its replacement. It is replaced by the Setting API and settings special variable. Generally, you would use this for data that does not change and should not be stored within story variables, which would make it part of the history. Note: Warning: Note: Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. See Guide: Media Passages for more information. If multiple passage titles are given, returns the lowest count (which can be -1). Loading is done asynchronously at run time, so if the script must be available within a tight time frame, then you should use the Promise returned by the function to ensure that the script is loaded before it is needed. 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. 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 delete all current watches, click the button. See the Config.passages.nobr setting for a way to apply the same processing to all passages at once. Any passage may be chosen as the starting passage by selecting it via the Start Story Here passage context-menu itemn.b. Warning: Repeatedly executes its contents after the given delay, inserting any output into the passage in its place. Determines whether the <> macro returns an error when the = assignment operator is used within its conditionale.g., <>. 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. See Setting API for more information. Note: See Also: Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. 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. 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. Track descriptor objects come in two forms and should have some of the noted properties: Deletes the playlist with the given list ID. Passage start. All changes within this version are breaking changes that you must address immediately. See Template API for more information. Finally, one of three things happen (in order): the existing playthrough session is restored, if it exists, else the autosave is loaded, if it exists and is configured to do so, else the starting passage is run. In general, you should not call this method directly. Creates a text input box, used to modify the value of the variable with the given name, optionally forwarding the player to another passage. For example: See: Once a track has been unloaded, playback cannot occur until it is reloaded. 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. Its contents are treated as raw HTML markupi.e., none of SugarCube's special HTML processing is performed. In mobile browsers, playback volume is controlled by the device hardware. Returns the given number clamped to the specified bounds. See the Macro API docs for more information. Removes classes from the selected element(s). sugarcube-2: macros: customMacroName: container: true anotherOne: {} If using *.twee-config . Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importScripts(). Returns the total number of available slots. Happens after the rendering of the incoming passage. Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. Local event triggered on the typing wrapper when the typing of a section stops. Returns whether a fade is in-progress on the track. See the State API docs for more information. Note: Returns a reference to the Dialog object for chaining. Player settings object, set up by the author/developer. Function templates should return a string, which may itself contain markup. Returns whether any valid sources were registered. Selects all internal link elements within the passage element whose passages are not within the in-play story historyi.e., passages the player has never been to before. 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. Sets the starting passage, the very first passage that will be displayed. Note: If the condition evaluates to false and an <> or <> exists, then other contents can be executed. To update the value associated with a key, simply set it again. This method will not detect "code" passagesi.e., script, stylesheet, and widget passages. Passage render. Note: Returns a random member from the array or array-like object. Sets story $variables and temporary _variables based on the given expression. You'll likely use story variables most often throughout your projectthough, temporary variables are perfect candidates for things like loop variables, if you're using the <> macro. You can see this effect by changing data outside the state. Unstows the UI bar, so that it is fully accessible again. See the :passagerender event for its replacement. The debug views may be toggled via the Views button. 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. Creates a link that silently executes its contents when clicked, optionally forwarding the player to another passage. The best example of an array is a pill container. 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. .one() in the jQuery API docs for more information. Starts playback of the playlist and fades the currently playing track from the specified volume level to 0 (silent) over the specified number of seconds. LoadScreen API. Warning: older versions of Twine2 used a icon for the same purpose. Harlowe's implementation of data types differs significantly from SugarCube's. SugarCube provides a variety of functions and methods that may be used instead, and standard JavaScript functions and methods may also be used. Returns a reference to the current AudioRunner instance for chaining. If you want to play tracks in a sequence, then you want a playlist instead. Call this only after populating the dialog with content. See the <> section of the Twine1 reference documentation for more information. Stops playback of the playlist and forces its tracks to drop any existing data. Equivalent to wrapping the entire passage in a <> macro. The playthrough session feature is occasionally confused with the autosave feature, but they are in fact distinct systems. For game-oriented projects, as opposed to more story-oriented interactive fiction, a setting of 1 is strongly recommended. Its return value should be the post-processed text. Stops playback of all currently registered tracks. Appends one or more unique members to the end of the base array and returns its new length. Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restartsn.b. Selects all internal link elements within the passage elemente.g., passage and macro links. Temporary variables were added in v2.3.0. Warning: Instead, call the UI.restart() static method, which prompts the player with an OK/Cancel dialog before itself calling Engine.restart(), if they accept. See the Setting API docs for more information. Generally, only really useful for running code that needs to manipulate elements from the incoming passage, since you must wait until they've been added to the page. Thus, you should only use plain HTML markup within the verbatim markupmeaning using none of SugarCube's special HTML attributes or directives. Note: Pauses playback of the selected tracks and, if they're not already in the process of loading, forces them to drop any existing data and begin loading. The Config.audio.pauseOnFadeToZero setting (default: true) determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). Note: Yes it is possible. Some browsers, particularly mobile ones, will free up memory by unloading web pages that are running in the background. 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. Anything from a number to a series of characters can be stored in a variable. Returns whether any moments with the given title exist within the extended past history (expired + past). TwineScript in SugarCube is, essentially, JavaScript with an extra spoonful of sugar on top to make it a bit nicer for the uninitiated. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. You may, however, simply use the Test Play From Here context menu item on the Start passage to achieve the same result. Config.saves.autosave setting, Config.saves.autoload setting, and Save API: Autosave. 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. The _contents special variable is used internally, by container widgets, to store the contents they enclose. 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. Be very careful with these if your audio sources are on the network, as you are forcing players to begin downloading them. The Config object controls various aspects of SugarCube's behavior. Returns the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. See the Save API docs for more information. Releases the loading screen lock with the given ID. An array is a container that holds things. Multiple <> macros may be set up to modify the same variable, which makes them part of a radio button group. Strings are iterated by Unicode code point, however, due to historic reasons they are comprised of, and indexed by, individual UTF-16 code units. Navigating back to a previous passage, for whatever reason, can be problematic. If you need them, then you'll need to use a class or similar non-generic object. Selects all external link elements within the passage elemente.g., links to other pages and websites. If no conditional expression is given, it is equivalent to specifying true. Note: The reason being is that the background property resets the background color, so if you do not set one either as one of its values or via a following background-color property, then the browser's default background color could show through if the background image does not cover the entire viewport or includes transparency. Performs any required processing before the save data is loadede.g., upgrading out-of-date save data. The seed is automatically included within saves and sessions, so this is not especially useful outside of debugging purposes. Activates the moment at the given index within the full state history and show it. Warning: Thus, all volume adjustments are ignored by the device, though muting should work normally. Note: As with <> and <
