You may forcibly enable test mode manually by setting the Config object's debug property to true. Multiple <> macros may be set up to modify the same variable, which makes them part of a radio button group. When a new moment is created, SugarCube stores the playthrough state to session storage.

The number of moments contained within the story history is, generally, limited, via the Config.history.maxStates setting. Attaches fullscreen error event handlers. Normally, those aren't issues as you should not need to use the result of an expression as an argument terribly often. Returns whether any of the given members were found within the array. See the _args special variable for its replacement. If the autosave exists and the story is configured to automatically load it, then the autosave is loaded and the state is replaced by the autosave's state and the active passage is rendered, just as if the user had loaded any other save. Values may be of most primitive types and some object types, see Supported Types for more information. Because of the additional HTML elements added by the debug views, some nested markup and selectors may be broken. SugarCube's DOM macros can target any HTML element on the page, not just hooks, and unlike their Harlowe equivalents, they cannot target arbitrary strings.

Returns a reference to the current AudioRunner instance for chaining. Collects tracks, which must be set up via <>, into a playlist via its <> children. 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. This video covers how to create the "Space Exploration" example in SugarCube 2.0.Harlowe: https://youtu.be/DvOPqJzXWgoSnowman: https://youtu.be/_G7tCGi8sLsPr.

For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. Tip: Deprecated: Warning: Creates a link that silently executes its contents when clicked, optionally forwarding the player to another passage. Group IDs allow several tracks to be selected simultaneously without needing to specify each one individually. The handler is passed one parameter, the save object to be processed. If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. The typed text has no default styling. Warning: #TwineTuesday: Twine 2 Basics (SugarCube) - Digital Ephemera Used within <> macros. Twine2: Unused. Passage navigation terminates all pending timed executions. Twine1/Twee: Required.

Displays the loading screen, if necessary. It is unlikely that you will ever want to disable this setting. Only useful when you have an asynchronous callback that invokes code/content that needs to access story and/or temporary variables shadowed by <>. .on() in the jQuery API docs for more information. When used to set the volume, returns a reference to the current AudioList instance for chaining. Moves backward one moment within the full history (past + future), if possible, activating and showing the moment moved to. Both of these features can be constructed in SugarCube, however, using macros like <> or by combining <> macros with DOM macros. Tag it with the appropriate media passage special tag, and only that tagsee below. Tip: Select "Change Story Format" and check the box next to "Sugarcube." Download PDF version: Variables and Programming in Twine See the :passagedisplay event for its replacement. Deprecated: Expressions are simply units of code that yield values when evaluated. 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. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). Returns the variables from the active (present) moment. Generates no output. See Dialog API for more information. Note: 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. As an example, the default replacement strings make use of this to handle various warning intros and outros. 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. To add watches for all current variables, click the button. Returns the last member from the array. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. To modify the values contained within variables, see the <> macro and setter links. In order of processing: (for reference, this also shows tasks and various special passages). Instead, use the metadata property. Global event triggered when all <> macros within a passage have completed. Configuration API. Assigns the value on the right-hand side of the operator to the left-hand side. Registers the passage as an initialization passage. You can use custom style markup or HTML to create the elements, and then target them with a query selector. May be terminated by a <> macro. .off() in the jQuery API docs for more information. You will also need some CSS styles to make this workexamples given below. Some browsers, particularly mobile ones, will free up memory by unloading web pages that are running in the background. Copy the following URL and paste it into the Add a New Format tab of the Formats menu, from Twine2's sidebar. The Non-generic object types (a.k.a. Returns whether, at least, the track's metadata has been loaded. Once the code has been fully executed, the contents of the buffer, if any, will be output. Audio lists (playlists) are useful for playing tracks in a sequencei.e., one after another. 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. Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restarts. If you need that kind of information from the dialog itself, then you may use the :dialogclosing event instead. Returns the number clamped to the specified bounds. A list definition object should have some of the following properties: Adds the named property to the settings object and a range control for it to the Settings dialog. To enable test mode from the story editor/map screen, click on the Test menu item (right side of the bottom bar). This method has been deprecated and should no longer be used. Warning: Twine 2.0 Harlowe Beginner's Guide | Gaming the Past Using State.active directly is generally unnecessary as there exist a number of shortcut properties, State.passage and State.variables, and story functions, passage() and variables(), which grant access to its normal properties. The verbatim HTML markup disables processing of all markup contained withinboth SugarCube and HTMLpassing its contents directly into the output as HTML markup for the browser. classes) guide for more information.

Sets the story's subtitle in the UI bar (element ID: story-subtitle). See Setting API for more information. Thus, it is only truly useful if you plan to upgrade out-of-date saves via a Config.saves.onLoad callback. Removes the audio group with the given ID. Deletes the specified on-save handler, returning true if the handler existed or false if not. 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. It has always been required that the call happen during story initialization, the only change is the throwing of the error. Controls the playback of the playlist, which must be set up via <>the deprecated <> may be used instead, though it is not recommended. For example: Captures story $variables and temporary _variables, creating localized versions of their values within the macro body. Returns the number of milliseconds that have passed since the current passage was rendered to the page. Returns whether playback of the track has ended. If you simply want to apply actions to multiple tracks simultaneously, then you want a group instead. See the Save.onSave.add() method for its replacement. Warning: Sets the selected tracks' volume level (default: 1). Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Note: Used for post-passage-display tasks, like redoing dynamic changes (happens after the rendering and display of each passage). The (execution) context object of the macro's parent, or null if the macro has no parent. Gets or sets the playlist's repeating playback state (default: false). Returns whether the history navigation was successful (should only fail if the index is not within the bounds of the full history). If no name is given, resets all settings. Does not modify the original. UI API. I've done it like this: $z= [ [1,2,3], [1,2,1], [4,4,0]] and it doesn't generate an error. Note: For the template that should be used as the basis of localizations, see the locale/l10n-template.js file @github.com. Furthermore, it is no longer instantiated into the legacy state objectwhich still exists, so legacy code will continue to work. Prior to SugarCube v2.10.0, the strings localization object was named strings. The handlers is passed two parameters, the save object to be processed and save operation details object. This method has been deprecated and should no longer be used. This macro has been deprecated and should no longer be used. Does not modify the original. See the <> macro for its replacement. This feature is largely incompatible with private browsing modes, which cause all in-browser storage mechanisms to either persist only for the lifetime of the browsing session or fail outright. In my version of Twine, the dialog box looks like this: In this dialog box, select the SugarCube alternative with the latest version number (SugarCube 2.x.x, the higher the numbers the better). Thus, storing them within story variables is generally wasteful. The maximum number of loop iterations in the conditional forms is not unlimited by default, however, it is configurable. StoryInit is run, as always. Note: The entire Options systemMenuOptions special passage, options special variable, and associated macroshas been scrapped for numerous reasonsit was always a hack, required copious amounts of boilerplate code to be useful, etc. Removes and returns the last member from the array, or undefined if the array is empty. The line continuation markup performs a similar function, though in a slightly different way. Note: Deprecated: . Note: TypeScript bindings for SugarCube APIs can found as the Definitely Typed package: @types/twine-sugarcube. Variables - Twine Cookbook See: SugarCube Snowman Arrays Arrays Chapbook Harlowe SugarCube Snowman Audio Audio Chapbook Harlowe SugarCube Snowman Conditional Statements . 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. If no conditional expression is given, it is equivalent to specifying true. Returns a reference to the current AudioTrack instance for chaining. Deprecated: Prepends one or more unique members to the beginning of the base array and returns its new length. The StoryInit special passage is normally the best place to set up groups. In both cases, since the end goal is roughly the same, this means creating a new instance of the base object type and populating it with clones of the original instance's data. You will, very likely, never need to use State.top directly within your code. Interrupts an in-progress fade of the selected tracks, or does nothing if no fade is progressing. Returns a new array consisting of the result of calling the given mapping function on every element in the source array and then concatenating all sub-array elements into it recursively up to a depth of 1. Warning: SugarCube provides a variety of functions and methods that may be used instead, and standard JavaScript functions and methods may also be used. Evaluates the given expression and compares it to the value(s) within its <> children. Text Adventure Command Input macro for SugarCube 2 and Twine. Passage display. A Quick Twine (2.2+) Tutorial: Computational Approaches to Narrative 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.
