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. 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. 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. The equivalent SugarCube code to achieve a similar result would be: Note: Sugarcube is a legacy version that supports the features and syntax of earlier Twine 1.x versions. To enable test mode from the story editor/map screen, click on the Test menu item (right side of the bottom bar). Stops playback of all currently registered tracks. Determines whether the UI bar (sidebar) starts in the stowed (shut) state initially. The loading process is as described in SimpleAudio.load(). Returns the bundled metadata, if any, or null if the given save could not be deserialized and loaded. Returns whether the track is currently unavailable for playback. The debug views themselves may be toggled on and off (default: on) via the Debug View button (top of the UI bar). Returns the AudioList instance with the given list ID, or null on failure. Note: This is not necessarily the same as the current state of the story: because moment creation is tied to passage navigation, changes that occur between one passage navigation and the next are not part of the current moment and will not be preserved by a moment until the next navigation, when the next moment is created. StoryInit is run, as always. Whenever your story is first started or, for any reason, restartede.g., the browser window/tab was refreshed/reloadedit undergoes its startup sequence. Tip: Examples of good uses: achievement tracking, new game+ data, playthrough statistics, etc. The value(s) within each case are compared to the result of the expression given to the parent <>. The document element. Gets or sets the playlist's randomly shuffled playback state (default: false). The function is invoked each time the .processText() method is called. Elements that are already part of the page, on the other hand, present no issues. Returns the value associated with the specified key from the story metadata store or, if no such key exists, the specified default value, if any. Arrays have many built-in methods and other features, and SugarCube adds many more. Attaches event handlers to the track. Twine 2: User Input in SugarCube Twine 2: Using Images in SugarCube Twine 2: Using Functions as Macros in Snowman Twine 2: Creating a Dungeon Crawler Part 1 Twine 2: Creating a Dungeon Crawler Part 2 Twine 2: Creating a Dating Sim Twine 2: Re-creating Candy Box Twine 2: Inventory Systems Twine 2: Murder Hill House Mystery Part 1 Global event triggered once just before the page is reloaded when Engine.restart() is called. See State API for more information. Return the named macro definition, or null on failure. Note: Arrays can be created by assigning a variable to the array literal, which is a pair of brackets ([]): <>. For example, if the passage name was Gone fishin', then: For example, if the tag name was Sector_42, then it would become both the data-tags attribute member Sector_42 (selector: [data-tags~="Sector_42"]) and the class sector-42 (selector: .sector-42). Returns whether playback of the playlist has been stopped. Temporary variables were added in v2.3.0. The template markup begins with a question mark (?) This is only really useful when you want to invoke a macro for its side-effects and aren't interested in its output. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . Warning: The Macros API object has been renamed to Macro and several of its methods have also changed, for better consistency with the other APIs. Payload objects have the following properties: The macro's definitioncreated via Macro.add(). Terminates the execution of the current iteration of the current <> and begins execution of the next iteration. UI API. Attaches single-use event handlers to the track. Twine2: Not special. Registers the passage as a VTT passage. The body of the page. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. The State.display() methodformerly state.display()is no longer overridable, meaning it cannot be wrappede.g., the "StoryRegions" 3rd-party add-ons do this. 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. See Also: The _args special variable is used internally to store arguments passed to the widgetas zero-based indices; i.e., _args[0] is the first parsed argument, _args[1] is the second, etcand the full argument string in raw and parsed formsaccessed via the _args.raw and _args.full properties. Returns whether the track's sources are currently unloaded. Returns a reference to the UIBar object for chaining. Appends one or more members to the end of the base array and returns its new length. This setting has been deprecated and should no longer be used. An array of discrete arguments parsed from the argument string. Note: A right angle bracket (>) that begins a line defines the blockquote markup. ended and pause for information on somewhat similar native events. Terminates the execution of the current <>. Outputs the contents of the passage with the given name, optionally wrapping it within an HTML element. Due to how SugarCube stores the state history a few constructs are not supported within story variables. In case you needed to do more than simply load the save, you may do something like the following: Returns a save as a serialized string, or null if saving is not allowed within the current context. 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. This method has been deprecated and should no longer be used. you'll need to call the Setting.save() after having done so. If SugarCube is reloaded by the browser for whatever reasone.g., due to a refresh, back/forward navigation, being unloaded in the background, etc.then the session is restored. If the condition evaluates to false and an <> or <> exists, then other contents can be executed. Return the named template definition, or null on failure. Silently executes its contents when the incoming passage is done rendering and has been added to the page. The pill container contains pills for each day of the week. See the <> macro for its replacement. Anyways, I wouldn't worry too much about maps or sets, but generic objects can be pretty useful, so I'd recommend understanding them. 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. Note: Happens after the displayi.e., outputof the incoming passage. 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. Returns whether the given substring was found within the string, starting the search at position. See Also: All widgets may access arguments passed to them via the _args special variable. Concatenates one or more unique members to the end of the base array and returns the result as a new array. Returns a reference to the current AudioRunner instance for chaining. This macro has been deprecated and should no longer be used. Note: Opens the built-in alert dialog, displaying the given message to the player. Returns whether an audio track with the given track ID exists. 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. No line-break control mechanisms are used in the following examples for readability. Returns a reference to the current AudioTrack instance for chaining. Returns the number of times that members within the array pass the test implemented by the given predicate function. See the memorize() and recall() functions for its replacement. Deletes all currently registered on-load handlers. SugarCube does not have any equivalents to Harlowe's (click:) family of macros. API members dealing with the history work upon either the active momenti.e., presentor one of the history subsets: the full in-play historyi.e., past + futurethe past in-play subseti.e., past onlyor the extended past subseti.e., expired + past. See the .includesAny() method for its replacement. True gapless transitions between tracks is not supported. Multiplies the current value on the left-hand side of the operator by the value on the right-hand side and assigns the result to the left-hand side. A version of the above code in SugarCube might look like this: Where Harlowe uses its hook syntax (square brackets) to associate a macro with its contents, SugarCube instead uses "container" macrosmacros that can have content associated with them have opening and closing tags. Outputs a string representation of the result of the given expression. For example, you might use the story variable $name to store the main player character's name or the story variable $cash to store how much money the player has on hand. To add watches for all current variables, click the button. This can be thought of as a special, temporary saved story, which is automatically deleted after the player's current browsing session ends. You will, very likely, never need to use State.current directly within your code. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. The Share dialog only displays linksspecifically, anything that creates an anchor element (). Twine1/Twee: Required. See the Localization guide for more information. This macro has been deprecated and should no longer be used. Each event is represented by an object that has properties that may be used to get additional information about what happened. Note: At the very least you will need to specify a .passage-out style that defines the transition's end state. The typed text has no default styling. Load and integrate external CSS stylesheets. Warning: Loading is done asynchronously at run time, so if the stylesheet must be available within a tight time frame, then you should use the Promise returned by the function to ensure that the stylesheet is loaded before it is needed. Unstows the UI bar, so that it is fully accessible again. Does not modify the original. This video covers how to create the "Space Exploration" example in SugarCube 2.0.Harlowe: https://youtu.be/DvOPqJzXWgoSnowman: https://youtu.be/_G7tCGi8sLsPr. prerender tasks have been deprecated and should no longer be used. It is replaced by the Setting API and settings special variable. NOTE: This should not be confused with story variables, which start with a $e.g., $foo. In Twine, you can combine the Set Macro with an If Macro to test is some condition is "true.". See the Config API docs for more information. A fullscreen options object should have some of the following properties: Note: SugarCube 2.x - The current version of SugarCube. The capitalization and punctuation used within the default replacement strings is deliberate, especially within the error and warning strings. Its return value should be the post-processed text. It has always been required that the call happen during story initialization, the only change is the throwing of the error. For example, the following will not work because the macro parser will think that you're passing five discrete arguments, rather than a single expression: You could solve the problem by using a temporary variable to hold the result of the expression, then pass that to the macro. Does not modify the original. 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. Used to replace SugarCube's default UI. 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. An array is just like a pill container except it can only contain one item. Returns whether playback of the track has been stopped. Request that the browser toggle fullscreen modei.e., enter or exit as appropriate. See the forget() function for its replacement. Creates a multiline text input block, used to modify the value of the variable with the given name. Executes its contents if the given conditional expression evaluates to true. Selects all internal link elements within the passage element who have been disablede.g., already chosen. Returns a reference to the Dialog object for chaining. Strings localization object. Note: The HTML & CSS have undergone significant changes. Warning: Function behavior is immutable. Returns a save object from the given slot or null, if there was no save in the given slot. Collects tracks, which must be set up via <>, into a group via its <
