Thus, a call to UIBar.stow() may also be necessary. Copy the following URL and paste it into the Add a New Format tab of the Formats menu, from Twine2's sidebar. Returns whether the given substring was found within the string, starting the search at position. Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. Returns a reference to the dialog's content area. Because the custom style markup uses the same tokens to begin and end the markup, it cannot be nested within itself. I've done it like this: $z= [ [1,2,3], [1,2,1], [4,4,0]] and it doesn't generate an error. Returns the string with its first Unicode code point converted to upper case. A set of opening and closing tagsi.e., defines the verbatim HTML markup. Returns whether the UI bar is currently stowed. Injecting additional <> macro invocations after a :typingcomplete event has been fired will cause another event to eventually be generated, since you're creating a new sequence of typing. An options object should have some of the following properties: Changes the disabled state of the target WAI-ARIA-compatible clickable element(s). This method will not return "code" passagesi.e., script, stylesheet, and widget passages. In SugarCube, the passage is not terminated, and anything in the code below the <> macro will have side effects. A set of four hyphen/minus characters (-) that begins a line defines the horizontal rule markup. 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. This functionally refreshes the webpage, and can cause users to lose their progress. For example: If you run the above, you'll see $x is 0. See the _args special variable for its replacement. The discrete argument type of macros are also fairly straightforward, most of the time, as you simply supply the requisite arguments separated by whitespace, which may include variablesas SugarCube automatically yields their values to the macro. For example, you may use the following JavaScript code to record the last non-menu passage into the $return story variable: (Twine2: the Story JavaScript, Twine1/Twee: a script-tagged passage). Load and integrate external JavaScript scripts. Returns whether all of the given members were found within the array. This setting is only used to set the version property of saves. Adds the value on the right-hand side of the operator to the current value on the left-hand side and assigns the result to the left-hand side. SugarCube Snowman Twine 2 Examples Twine 2 Examples . Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restarts. Returns whether the given slot is filled. Returns the total number of available slots. Warning: Does not modify the original. Request that the browser exit fullscreen mode. The Macros API object has been renamed to Macro and several of its methods have also changed, for better consistency with the other APIs. Warning: Twine2: Not special. Appends one or more unique members to the end of the base array and returns its new length. Controls the playback of the playlist, which must be set up via <>the deprecated <> may be used instead, though it is not recommended. Hides the loading screen, if no other locks exist. Should the history exceed the limit, states will be dropped from the past (oldest first). The handler is passed one parameter, the save object to be processed. Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. 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. Warning: Prepends one or more unique members to the beginning of the base array and returns its new length. The playthrough session feature is occasionally confused with the autosave feature, but they are in fact distinct systems. 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. They are called with no arguments, but with their this set to a template (execution) context object that contains the following data properties: String templates consist solely of a string, which may itself contain markup. See Passage API for more information. Note: 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. Warning: Silently executes its contents when the incoming passage is done rendering and has been added to the page. 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. Returns the first member from the array. In mobile browsers and, more recently, most desktop browsers, playback must be initiated by the playergenerally via click/touch. Returns whether the UI bar is currently hidden. If its return value is falsy, the save is disallowed. See Story API for more information. 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. Harlowe's implementation of the (goto:) macro terminates the rendering passage. May also be, and often is, used to add additional story UI elements and content to the UI bar. Functionally identical to <>. 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. 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. A save operation details object will have the following properties: Deletes all currently registered on-save handlers. Collects tracks, which must be set up via <>, into a group via its <> children. Note: Used for post-passage-display tasks, like redoing dynamic changes (happens after the rendering and display of each passage). The second, and also mandatory, character of the variable name may be one of the following: the letters A though Z (in upper or lower case), the dollar sign, and the underscore (i.e., A-Za-z$_)after their initial use as the sigil, the dollar sign and underscore become regular variable characters. Note: Circular references. Does not flag other assignment operators. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. Unsets story $variables and temporary _variables. See Save API for more information. Note: Returns whether none of the track's data has been loaded. The document element. predisplay tasks have been deprecated and should no longer be used. Passage end. Deprecated: The (execution) context object of the macro's parent, or null if the macro has no parent. Requires tracks to be set up via <>. Selects the element that contains passage elements. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. The audio subsystem that supports the audio macros comes with some built-in limitations and it is strongly recommended that you familiarize yourself with them. Note: Returns the variables from the active (present) moment. See Macro API for more information. 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. SugarCube SugarCube is a free (gratis and libre) story format for Twine/Twee. Returns a pseudo-random whole number (integer) within the range of the given bounds (inclusive)i.e., [min,max]. Once the code has been fully executed, the contents of the buffer, if any, will be output. Returns the number of turns that have passed since the last instance of the passage with the given title occurred within the story history or -1 if it does not exist. Then close the dialog box. Dialog API. To enable test mode from the story editor/map screen while starting at a specific passage, hover over a passage and select the menu item. In general, look to the, Replaced the ungainly link text syntax, The various Options macros have been removed. To resolve instances where you do, however, you'll want to use either a temporary variable or a backquote expression. Creates a single-use passage link that deactivates itself and all other <> links within the originating passage when activated. See Template API for more information. Note: Randomly selects the given number of unique members from the base array and returns the selected members as a new array. In use, replacement patterns are replaced recursively, so replacement strings may contain patterns whose replacements contain other patterns. Does not modify the original. Attaches event handlers to the selected tracks. See Tweego's documentation for more information. This method will not detect "code" passagesi.e., script, stylesheet, and widget passages. Fullscreen requests must be initiated by the player, generally via click/touchi.e., the request must be made as a result of player interaction; e.g., activating a button/link/etc whose code makes the request. Returns a reference to the active (present) story variables store (equivalent to: State.variables). SugarCube uses .ariaClick() internally to handle all of its various link markup and macros. Does not modify the original. An array of discrete arguments parsed from the argument string. See the .includes() method for its replacement. See the State.prng.init() method for its replacement. . Note: Creates a single-use link that deactivates itself and replaces its link text with its contents when clicked. The HTML & CSS have undergone significant changes. SugarCube provides a variety of functions and methods that may be used instead, and standard JavaScript functions and methods may also be used. 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. Generates no output. For example, if the name of SugarCube's directory is sugarcube, then the name of the .py file within must be sugarcube.py. Note: 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. Returns the number of currently registered on-save handlers. A right angle bracket (>) that begins a line defines the blockquote markup. Returns whether an audio track with the given track ID exists. Deprecated: Appends one or more members to the end of the base array and returns its new length. Etc. Reloading the page or revisiting a passage may not restore the state of some interactive macros, so it is recommended that you only use them in instances where this will not be an issue or where you can work around it. This setting has been deprecated and should no longer be used. Used to populate the contents of the Share dialog. Note: This does not alter the volume level. classes) guide for more information. See <> for more information. ended and pause for information on somewhat similar native events. 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. SugarCube, like JavaScript, uses dynamic typing. Not everyone has Due to various limitations in its design, if you're using Twine2 as your IDE/compiler, then it is strongly recommended that you do not create more than a few media passages and definitely do not use large sources. Returns whether the full in-play history (past + future) is empty. Stops playback of the selected tracks and forces them to drop any existing data. Note: Deprecated: Returns a reference to the current temporary variables store (equivalent to: State.temporary). Deprecated: See the Dialog API docs for more information. Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. Temporary variables were added in v2.3.0. There are two primary branches of Twine2 as far as SugarCube is concerned: Regardless of the version of Twine2 you're using, follow these instructions to install a local copy of SugarCube v2: Note: Note: Prepends one or more members to the beginning of the base array and returns its new length. See Also: This method is meant to work with clickables created via .ariaClick() and may not work with clickables from other sources. Returns the Passage object referenced by the given title, or an empty Passage object on failure. You may forcibly enable test mode manually by setting the Config object's debug property to true. Return the named macro definition, or null on failure. Text Adventure Command Input macro for SugarCube 2 and Twine. Returns whether any valid sources were registered. Views make their associated code visible, thus providing onscreen feedbackthey may also be hovered over which, generally, exposes additional information about the underlying code. 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. Deprecated: See: Player settings object, set up by the author/developer. Returns a reference to the Dialog object for chaining. There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. Note: See Config.macros.maxLoopIterations for more information. 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. 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. Ideally, if you need to update UI bar content outside of the normal passage navigation update, then you should update only the specific areas you need to rather than the entire UI bar. CSS styles cascade in order of load, so if you use multiple stylesheet tagged passages, then it is all too easy for your styles to be loaded in the wrong order, since Twine1/Twee gives you no control over the order that multiple stylesheet tagged passages load. Generates no output. Skips ahead to the next track in the playlist, if any. Returns a random value from its given arguments. Note: Note: Deletes the audio track with the given track ID. You can have it hold numbers, text, and even other arrays! A prototype-less generic object whose properties and values are defined by the Setting.addToggle(), Setting.addList(), and Setting.addRange() methods. Returns whether fullscreen is both supported and enabled. Warning: See: Warning: Making custom non-generic object types fully compatible requires that two methods be added to their prototype, .clone() and .toJSON(), to support cloningi.e., deep copyinginstances of the type. See: If setting a background image via the background shorthand property, then you should also specify a background-color value with it or include a separate background-color property after the background property. It should be plain text, containing no code, markup, or macros of any kind. SugarCube does not have any equivalents to Harlowe's (click:) family of macros. It consists of one or more right angle brackets, each additional one beyond the first signifying a level of nested blockquote. This does not reclaim the space reserved for the UI bar. Generates no output. Arrays have many built-in methods and other features, and SugarCube adds many more. A fullscreen options object should have some of the following properties: Note: Stops playback of the track and forces it to drop any existing data. Does not modify the original. 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. Provides access to browsers' fullscreen functionality. SimpleAudio API. Note: Outputs a string representation of the result of the given expression. Returns whether a playlist with the given list ID exists. Used to replace SugarCube's default UI. 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. Opens the built-in settings dialog, which is populated from the Setting API. The config object has been renamed to Config and some of its properties have also changed. There are also "tags", which are basically arrays of values on a property of a bag or item. Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Its contents are treated as raw HTML markupi.e., none of SugarCube's special HTML processing is performed. Returns the number of existing templates. And feedback from the folks over at the Twine Games Discord Server. Here's a simple example whose constructor takes a single config/option object parameter: Creating a new instance of this ContactInfo example would be something like: Here's a simple example whose constructor takes multiple discrete parameters: Here's a simple example whose constructor takes multiple discrete parameters, but also includes an ._init() helper method to allow the .clone() and .toJSON() methods to require less manual tinkering than the previous discrete parameters example by automatically copying an instance's own data: Media passages are simply a way to embed media into your projectspecially tagged passages that contain the data URI of a Base64-encoded media source. Payload objects have the following properties: The macro's definitioncreated via Macro.add(). While it renders content just as any other passage does, instead of displaying the rendered output as-is, it sifts through the output and builds its menu from the generated links contained therein. Note: Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. Note: Note: Navigation events allow the execution of JavaScript code at specific points during passage navigation. 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 whether the history navigation was successful (should only fail if already at the beginning of the full history). Twine1/Twee: Registers the passage as JavaScript code, which is executed during startup. Note: Returns the whole (integer) part of the given number by removing its fractional part, if any. Returns a reference to the current AudioRunner instance for chaining.
