However, this means that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. Warning: The Config API serves the same basic purpose. 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. The argument string after converting all TwineScript syntax elements into their native JavaScript counterparts. Returns whether the full in-play history (past + future) is empty. You cannot obtain data about the closing dialog from the dialog itselfe.g., title or classeswhen using the :dialogclosed event, as the dialog has already closed and been reset by the time the event is fired. Opens the built-in restart dialog, prompting the player to restart the story. Config.macros.typeSkipKey, Config.macros.typeVisitedPassages, <> Events. 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. See the _args special variable for its replacement. May be terminated by a <> macro. For each iteration, it assigns the key/value pair of the associated entry in the collection to the iteration variables and then executes its contents. In your menu passages, your long return links will simply reference the $return story variable, like so: Warning (Twine2): Used within <> macros. Note: These instances will be noted. Warning: I've been trying to set up a two-dimensional array. All these instructions are based on the SugarCube story format. The JSON.reviveWrapper() method for additional information on implementing the .toJSON() method. Gets or sets the mute state for the master volume (default: false). Deprecated: The callback is passed one parameter, the original destination passage title. 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. prehistory tasks have been deprecated and should no longer be used. ( 2021-12-20) Fixed an issue with the selected keyword in the <<cycle>> and <<listbox>> macros' <<option>> tags. Note: Return the named macro definition, or null on failure. Note: Tip: 558 30K views 7 years ago Introduction to Twine In this new series, I cover the process of writing interactive fiction using Twine and the Sugarcube story format. Note: SugarCube Snowman Arrays Arrays Chapbook Harlowe SugarCube Snowman Audio Audio Chapbook Harlowe SugarCube Snowman Conditional Statements . You can set the autosave to save either on every passage or only on certain passages. See the :passagerender event for its replacement. For example, a common use of <> macro. 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. 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. Returns a reference to the UIBar object for chaining. Returns whether, at least, the track's metadata has been loaded. Object that authors/developers may use to set up various bits of static data. Unfortunately, due to limitations in the current release of Twine1, the Build menu's Test Play menu item is not able to trigger test mode. 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. Deprecated: Macro handlers are called with no arguments, but with their this set to a macro (execution) context object. The debug views themselves may be toggled on and off (default: on) via the Debug View button (top of the UI bar). Harlowe's arrays, datamaps, and datasets are functionally similar to JavaScript Arrays, Maps, and Sets, but with a few key differences. Deprecated: See Also: The StoryInit special passage is normally the best place to set up groups. Note: Warning: If no conditional expression is given, it is equivalent to specifying true. Save API. Note: Displays the loading screen until all currently registered audio has either loaded to a playable state or aborted loading due to errors. To jump to any moment/turn within the available history, select the moment/turn from the Turn select field. The Config.debug setting for more information. The verbatim text markup disables processing of all markup contained withinboth SugarCube and HTMLpassing its contents directly into the output as plain text. The Fullscreen API comes with some built-in limitations: Returns the current fullscreen element or, if fullscreen mode is not active, null. SugarCube uses .ariaClick() internally to handle all of its various link markup and macros. This macro has been deprecated and should no longer be used. Randomly removes the given number of members from the base array and returns the removed members as a new array. blazing fast internet with unlimited dataespecially true for mobile users. Attempting to do so will, usually, result in something that's non-functional. 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. 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. Note: Deprecated: Once unloaded, playback cannot occur until the selected tracks' data is loaded again. Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. 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. 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. Save objects have some of the following properties: The state object has the following properties: Each moment object has the following properties: Deletes all slot saves and the autosave, if it's enabled. See Template API for more information. Does not modify the original. Controls the playback of audio tracks, which must be set up via <>. Gets or sets the track's volume level (default: 1). Examples of good uses: achievement tracking, new game+ data, playthrough statistics, etc. See the .includesAny() method for its replacement. [SugarCube 2.21.0] Two-dimensional arrays. System events allow the execution of JavaScript code at specific points during story startup and teardown. Loose URLs are imported concurrently, arrays of URLs . If you don't know what that means, then this API is likely not for you. You can use custom style markup or HTML to create the elements, and then target them with a query selector. Returns the AudioList instance with the given list ID, or null on failure. Doing so allows interactions with the text to also trigger its <>. As with all special tags, media passage tags are case sensitive, so their spelling and capitalization must be exactly as shown. Returns a pseudo-random decimal number (floating-point) within the range of the given bounds (inclusive for the minimum, exclusive for the maximum)i.e., [min,max). See the <> macro for its replacement. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . The DOM ID of the passage, created from the slugified passage title. Only when manually modifying the values of settings object properties, outside of the controls, would you need to call this method. If its return value is falsy, the override is cancelled and navigation to the original destination continues unperturbed. If you need them, then you'll need to use a class or similar non-generic object. This setting exists to prevent a misconfigured loop from making the browser unresponsive. 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. Removes all of the members at the given indices from the array and returns a new array containing the removed members. Does not modify the original. Returns whether there are any filled slots. Sylen. Warning: SugarCube does not have any equivalents to Harlowe's (click:) family of macros. Due to how the Twine2 automatic passage creation feature currently works, using the link markup form will cause a passage named $return to be created that will need to be deleted. May be called with, optional, link text or with a link or image markup. Returns a reference to the current AudioRunner instance for chaining. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). This is chiefly intended for use by add-ons/libraries. Audio, image, video, and VTT passages are supported. In that case, unless you need to dynamically determine the destination passage within the <> is unnecessary as <.processText() method is called. Returns a reference to the current temporary variables store (equivalent to: State.temporary). Next, the StoryInit special passage is processed. Returns whether the history navigation was successful (should only fail if the index is not within the bounds of the full history). To enable test mode from the Stories screen, click on the story's gear menu and select the Test Story menu item. Generates no output. Opens the built-in jump to dialog, which is populated via the bookmark tag. Deprecated: Returns a reference to the current AudioTrack instance for chaining. By convention, properties starting with an underscoree.g., _warningIntroLackingare used as templates, only being included within other localized strings. The UISystem API object has been split into two APIs Dialog and UI, and some of its methods have also changed. Returns the moment, relative to the bottom of the past in-play history (past only), at the given index. Note: State.top is not a synonym for State.active. Prepares the dialog for use and returns a reference to its content area. 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. Setting API method calls must be placed within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or settings will not function correctly. 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. 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. Creates a link that navigates forward to a previously visited passage. The most interesting of which, from an end-user's standpoint, are 410. Generally, this means only when the variable's value will change between the time the asynchronous macro is invoked and when it's activatede.g., a loop variable. Returns whether playback of the track has been paused. ended and pause for information on somewhat similar native events. This setting is only used to set the version property of saves. Returns whether the named template exists. The template markup begins with a question mark (?) Returns the save object from the autosave or null, if there was no autosave. Causes any output generated within its body to be discarded, except for errors (which will be displayed). Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. SugarCube is a free (gratis and libre) story format for Twine/Twee. The equivalent SugarCube code to achieve a similar result would be: Note: Macro context objects contain the following data and method properties. If no name is given, resets all settings. Warning: This is only really useful within pure JavaScript code, as within TwineScript you may simply access story variables natively. Determines whether the UI bar (sidebar) starts in the stowed (shut) state initially. Note: You can have it hold numbers, text, and even other arrays! Compilers supporting automatic creation of media passages: Warning (Twine2): Text Adventure Command Input macro for SugarCube 2 and Twine. May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. Roughly equivalent to the :passagerender event. It is strongly recommended that you do not place background properties on the html element in addition to the body element as this can cause background jitter in Internet Explorer when scrolling outside of fullscreen mode. Passing the name of a variable as an argument is problematic because variable substitution occurs automatically in SugarCube macros. Tip: If its return value is truthy, the override succeeds and that value is used as the new destination of the navigation. Note: Thus, you should only use plain HTML markup within the verbatim markupmeaning using none of SugarCube's special HTML attributes or directives. 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. An array of strings, which causes the autosave to be updated for each passage with at least one matching tag. Follow these instructions to install a local copy of SugarCube v2: If you followed the steps correctly, within Twine1/Twee's targets directory you should now have a sugarcube-2 directory, which contains several filese.g., header.html, sugarcube-2.py, etc. Create a save, then edit the code as follows: Running that, you'll see $x is 0 and $y is 1. Note: Audio lists (playlists) are useful for playing tracks in a sequencei.e., one after another. Attaches fullscreen error event handlers. with 2.0. Selects all internal link elements within the passage element who have been disablede.g., already chosen. Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. Note: StoryInit is run, as always. Happens after the displayi.e., outputof the incoming passage. Warning: . This is a reference for localizing SugarCube's default UI text, in general, and its l10nStrings object specifically. Returns whether the named macro tag exists. The SaveSystem API object has been renamed to Save and several of its methods have also changed, for better consistency with the other APIs. Used to populate the story's caption area in the UI bar (element ID: story-caption). All special names listed herein are case sensitive, so their spelling and capitalization must be, When the active passage, it would become the ID. Stows the UI bar, so that it takes up less space. 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. Displays the loading screen until all currently registered audio tracks have either loaded to a playable state or aborted loading due to errors. See Also: SugarCube is a free (gratis and libre) story format for Twine/Twee. Returns whether playback of the track has ended. UI API. Sets the default KeyboardEvent.key value that causes the currently running <> macro instance to finish typing its content immediately. 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. If you've removed/hidden the UI bar, a construct like the following will allow you to toggle the views on and off: Note: The exactly equivalent call is: .flat(Infinity). SugarCube also allows the use of JavaScript generic objects, which may be better in some situations than a map: Another important difference in the way Harlowe handles its non-primitive data types like arrays, datamaps, and datasets is that they are passed by value rather than passed by reference. Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Tip: Select "Change Story Format" and check the box next to "Sugarcube."

The DOM ID of the story, created from the slugified story title. Note: Use the Edit Story Stylesheet story editor menu item for styles. 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. To avoid this problem, it's suggested that you use the separate argument form of the <> for more information. Opens the built-in settings dialog, which is populated from the Setting API. Probably most useful when paired with <>. To actually affect multiple tracks and/or groups, see the SimpleAudio.select() method. This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. There are cases, however, where things get a bit more complicated, namely: instances where you need to pass the name of a variable as an argument, rather than its value, and those where you want to pass the result of an expression as argument. Note: Note: When the story is restarted by SugarCube rather than refreshed via the browser, the playthrough session, if any, is not loaded. When used to set the loop state, returns a reference to the current AudioTrack instance for chaining. Does not modify the original. If your content contains any SugarCube markup, you'll need to use the Dialog.wiki() method instead. See the. Note: Global event triggered once just before the dismissal of the loading screen at startup. If the autosave cannot be loaded, for any reason, then the start passage is loaded instead. SugarCube. 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. The line continuation markup performs a similar function, though in a slightly different way. 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. Gets or sets the mute-on-hidden state for the master volume (default: false). We'll cover some of these differences below. The core audio subsystem and backend for the audio macros. Deserializes the given save string, created via Save.serialize(), and loads the save. Subsequent, optional, characters have the same set as the second with the addition of numerals (i.e., 0-9, so the full set is A-Za-z0-9$_). Returns the given string with all regular expression metacharacters escaped. If the full path to the contents of the archive is something like: Then the file URL to it would be (note the changed slashes): The online SugarCube install, delivered by the jsDelivr CDN, supports only versions of Twine2 2.1. TwineScript in SugarCube is, essentially, JavaScript with an extra spoonful of sugar on top to make it a bit nicer for the uninitiated. See Also: you'll need to call the Setting.save() after having done so. For example: Captures story $variables and temporary _variables, creating localized versions of their values within the macro body. Returns the number of moments within the past in-play history (past only). Returns a reference to the Dialog object for chaining. This functionally refreshes the webpage, and can cause users to lose their progress. Shows the UI bar. Opens the dialog. June 2017 in Help! Track event triggered when a fade completes normally. Returns the current state of the engine ("idle", "playing", "rendering"). Returns the number of milliseconds that have passed since the current passage was rendered to the page. All changes within this version are elective changes that you may address at your leisure. 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 the number of times that the passage with the given title occurred within the story history. See the <> macro for its replacement. Returns a new array containing all of the macro's ancestors that passed the test implemented by the given filter function or an empty array, if no members pass. Interactive macros are both asynchronous and require interaction from the player. The handlers is passed two parameters, the save object to be processed and save operation details object. Returns the title of the active (present) passage. 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 the Save API docs for more information. This macro is functionally identical to <>, save that it also encodes HTML special characters in the output. Note: 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. Returns the variables from the active (present) moment. Note: Elements that include either a data-init-passage or data-passage content attribute should not themselves contain additional elementssince such elements' contents are replaced each turn via their associated passage, any child elements would be lost. Generates no output. Once unloaded, playback cannot occur until the track's data is loaded again. This macro has been deprecated and should no longer be used. Documentation, downloads, and the like can be found within each section. The loading process is as described in SimpleAudio.load(). This is an estimate calculated by the browser based upon the currently downloaded data and the download rate. Note (Twine2): Note: See the Dialog API docs for more information. If you're on Linux, right-click on the file and select Copy. 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.
