The autosave feature is occasionally confused with the playthrough session feature, but they are in fact distinct systems. Returns whether any of the macro's ancestors passed the test implemented by the given filter function. 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. Note: Selects all internal link elements within the passage element who have been disablede.g., already chosen. Instance methods of classes are not affected by either issue, as they're never actually stored within story variables, being referenced from their classes' prototypes instead. Does not flag other assignment operators. Executes its contents and outputs the result, after removing leading/trailing newlines and replacing all remaining sequences of newlines with single spaces. Returns whether any of the target WAI-ARIA-compatible clickable element(s) are disabled. Anyways, I wouldn't worry too much about maps or sets, but generic objects can be pretty useful, so I'd recommend understanding them. <> does not terminate passage rendering in the passage where it was encountered, so care must be taken to ensure that no unwanted state modifications occur after its call. 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. Equivalent to wrapping the entire passage in a <> macro. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. Track event triggered when playback is stopped after .stop() or .stop() is calledeither manually or as part of another process. TypeScript bindings for SugarCube APIs can found as the Definitely Typed package: @types/twine-sugarcube. 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 an AudioRunner instance for the tracks matching the given selector. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. 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. SugarCube includes polyfills for virtually all JavaScript (ECMAScript) 5 & 6 native object methodsvia the es5-shim and es6-shim polyfill libraries (shims only, no shams)so they may be safely used even if your project will be played in ancient browsers that do not natively support them. Harlowe's implementation of the (goto:) macro terminates the rendering passage. 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. 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. This function is finicky, however. Returns the playlist's current time in seconds, or NaN if no metadata exists. that begins a line defines the heading markup. Happens after the rendering of the incoming passage. Twine1/Twee: Registers the passage as JavaScript code, which is executed during startup. Thus, you should only use plain HTML markup within the verbatim markupmeaning using none of SugarCube's special HTML attributes or directives. System events allow the execution of JavaScript code at specific points during story startup and teardown. June 2017 in Help! The equivalent SugarCube code to achieve a similar result would be: Note: 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. The Macros API object has been renamed to Macro and several of its methods have also changed, for better consistency with the other APIs. Sets the maximum number of iterations allowed before the <> macro conditional forms are terminated with an error. There are also "tags", which are basically arrays of values on a property of a bag or item. Only when manually modifying the values of settings object properties, outside of the controls, would you need to call this method. Concatenates one or more unique members to the end of the base array and returns the result as a new array. Shorthand for jQuery's .off() method applied to each of the audio elements. Returns a reference to the UIBar object for chaining. Cannot delete tracks solely under the control of a playlist. If you have a property that uses an array of values, you will be able to use the various "tag" functions to . This functionally refreshes the webpage, and can cause users to lose their progress. Local event triggered on the typing wrapper when the typing of a section starts. 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 contents from the generated links contained therein. Gets or sets the playlist's volume level (default: 1). child-definition array) optional: If the macro has children, specify them as an array of strings or . You will, in all likelihood, use expressions most often within macrose.g., <>, <>, <>, <>. The story menu only displays linksspecifically, anything that creates an anchor element (). If its return value is falsy, the override is cancelled and navigation to the original destination continues unperturbed. Deprecated: Yes it is possible. Activates the moment at the given index within the full state history and show it. Be very careful with these if your audio sources are on the network, as you are forcing players to begin downloading them. Happens before the end of passage navigation. Returns the number of currently registered on-load handlers. The predefined variable output, which is a reference to a local content buffer, is available for use within the macro's code contents. 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. If you plan on using interactive macros within a loop you will likely need to use the. Outputs a string representation of the result of the given expression. SugarCube does not support the Twine1.4+ vanilla story formats' tagged stylesheets. Returns the AudioList instance with the given list ID, or null on failure. May be called either with the passage name and link text as separate arguments, with a link markup, or with a image markup. Instead, call the UI.restart() static method, which prompts the player with an OK/Cancel dialog before itself calling Engine.restart(), if they accept. Opens the built-in share dialog, which is populated from the StoryShare passage. Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. Warning: This setting has been deprecated and should no longer be used. Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importStyles(). The controls of the Settings dialog automatically call this method when settings are changed, so you should normally never need to call this method manually. Returns whether the given member was found within the array, starting the search at position. Warning: Because the custom style markup uses the same tokens to begin and end the markup, it cannot be nested within itself. The document element. Once a track has been unloaded, playback cannot occur until it is reloaded. Note: Arrays in Sugarcube have a built-in function that lets you delete elements from them by name. Determines whether alternate passage descriptions are used by the Saves and Jump To menusby default an excerpt from the passage is used. Returns the number of passages within the story history that are tagged with all of the given tags. Note: 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. Note: 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. Now, whenever you type <<status>>, Twine will print out all stats as set up within the widget, like for example: Strength: Weak Dexterity: Dextrous . Returns a reference to the UIBar object for chaining. Returns whether the UI bar is currently stowed. Terminates the execution of the current iteration of the current <> and begins execution of the next iteration. Passage API. Executes its contents and replaces the contents of the selected element(s) with the output. 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. Returns whether the autosave is available and ready. SugarCube features a configurable autosave system. Returns whether an audio track with the given track ID exists. 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. Return the named macro definition, or null on failure. Returns the number of times that the given member was found within the array, starting the search at position. Deletes the specified on-save handler, returning true if the handler existed or false if not. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. In most cases of using variables in Twine, you will want to first "set" some value and then, at some later point, conditionally act from testing the value. Request that the browser enter fullscreen mode. Several UI API methods have moved to the new Dialog API. Strings in TwineScript/JavaScript are Unicode, however, due to historic reasons they are comprised of, and indexed by, individual UTF-16 code units rather than code points. Returns the variables from the active (present) moment. Global event triggered when all <> macros within a passage have completed. Returns how much remains of the playlist's total playtime in seconds, Infinity if it contains any streams, or NaN if no metadata exists. Returns the total number of filled slots. . Note: depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. For normal projects, authors are encouraged to continue to use the StoryInit special named passage. If you wish to use custom backgrounds, either simply colors or with images, then you should place them on the body element. Those that bundle SugarCube v2: Any series of Twine2 with a version 2.1. Returns whether, at least, the track's metadata has been loaded. A function, which causes the autosave to be updated for each passage where its return value is truthy. Deprecated: Warning: postdisplay tasks have been deprecated and should no longer be used. Navigation events allow the execution of JavaScript code at specific points during passage navigation. Returns whether the history navigation was successful (should only fail if already at the beginning of the full history). Warning: Note: You must provide your own styling for the link-visited class as none is provided by default. Returns whether the specified key exists within the story metadata store. See the Save API docs for more information. Returns a reference to the current AudioTrack instance for chaining. Returns whether the dialog is currently open. 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. See the :passagedisplay event for its replacement. Object that authors/developers may use to set up various bits of static data. They are defined via the Template API. TwineScript in SugarCube is, essentially, JavaScript with an extra spoonful of sugar on top to make it a bit nicer for the uninitiated. Returns whether fullscreen is both supported and enabled. Returns the number of milliseconds that have passed since the current passage was rendered to the page. The (execution) context object of the macro's parent, or null if the macro has no parent. Executes its contents and prepends the output to the contents of the selected element(s). . It is strongly recommended that you use only one stylesheet passage. Returns a reference to the UIBar object for chaining. A fullscreen options object should have some of the following properties: Note: Stops playback of the playlist and forces its tracks to drop any existing data. 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. Instances of the Passage object are returned by the Story.get() static method. In your menu passages, your long return links will simply reference the $return story variable, like so: Warning (Twine2): In general, look to the .random() method instead. Deprecated: Displays the loading screen, if necessary. Saving the story records the story's state up until the last moment that was created. 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. Note: Assigns the value on the right-hand side of the operator to the left-hand side. Returns a reference to the current AudioRunner instance for chaining. 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. Returns the given number clamped to the specified bounds. Note: Only deletes the group itself, does not affect its component tracks. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. Releases the loading screen lock with the given ID. Warning: Interrupts an in-progress fade of the currently playing track, or does nothing if no fade is progressing. This is not an exhaustive list. an array holding the names of the days of the week) on a story variable, it should be stored on the SugarCube setup object variable instead. Twine1/Twee: Required. Removes event handlers from the track. The core menu item for the Settings dialog. Does not modify the original. Opens the dialog. Selects the passage element. Does not modify the original. Triggered at the end of passage navigation. When used to set the mute state, returns a reference to the current AudioList instance for chaining. Browsers are not currently required to honor the navigationUI setting. For example: Determines whether the output of the Wikifier is post-processed into more sane markupi.e., where appropriate, it tries to transition the plethora of
elements into elements. Note: Used to populate the contents of the Share dialog. Story variables are a part of the story history and exist for the lifetime of a playthrough session.

Note: Deprecated: Returns the number of times that the passage with the given title occurred within the story history. Unless localized by use of the <> macro, any story or other temporary variables used within widgets are part of a story's normal variable store, so care must be taken not to accidentally either overwrite or pick up an existing value. you'll need to call the Setting.save() after having done so. Do not add a widget tag to any of the specially named passages and attempt to define your widgets there. Warning: 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. Return the named template definition, or null on failure. This feature also prevents players from losing progress if they try to use the browser back and forward buttons to navigate, or if they refresh their browser for any reason. Registers the passage as an initialization passage. In Twine, return to your project library by clicking the house icon in the lower-left corner of the Twine window. For example: While every valid expressioneven those you might not expectyields a value, there are essentially two types of expressions: those with side effects and those without.
