Returns a reference to the Dialog object for chaining. Thus, storing them within story variables is generally wasteful. It should be plain text, containing no code, markup, or macros of any kind. See the <> macro for its replacement. In versions of SugarCube v2.23.0, the debugging interface offers additional tools, namely variable watches and arbitrary history navigation. Returns a callback function that wraps the specified callback functions to provide access to the variable shadowing system used by the <> macro. 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. 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. Note: This means that some code points may span multiple code unitse.g., the emoji is one code point, but two code units. Copy the following URL and paste it into the Add a New Format tab of the Formats menu, from Twine2's sidebar. Consider the following Harlowe link macros: The equivalent SugarCube code for each link might look something like this: SugarCube's <> and <> macros can also accept the link markup as an argument: Note: 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. Once initialized, the State.random() method and story functions, random() and randomFloat(), return deterministic results from the seeded PRNGby default, they return non-deterministic results from Math.random(). This is only really useful when you want to invoke a macro for its side-effects and aren't interested in its output. Collects tracks, which must be set up via <>, into a playlist via its <> children. Gets or sets the master volume level (default: 1). For example, a common use of <> is to perform various actions before forwarding the player to another passage. Determines whether rendering passages have their leading/trailing newlines removed and all remaining sequences of newlines replaced with single spaces before they're rendered. Does not modify the original. Returns a new array consisting of the flattened source array. Note: 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. The number of moments contained within the story history is, generally, limited, via the Config.history.maxStates setting. Note: StoryMenu, etc. Note: Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. Returns the given number clamped to the specified bounds. Executes its contents and appends the output to the contents of the selected element(s). Returns a save object from the given slot or null, if there was no save in the given slot. Thus, a call to UIBar.stow() may also be necessary. State.prng.init() must be called during story initialization, within either your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or the StoryInit special passage. However, I've tried to use elements in these arrays, like this: $y=$z [0] [2] and it doesn't seem to work. Most of the methods listed below are SugarCube extensions, with the rest being either JavaScript natives or bundled library methods that are listed here for their utilitythough, this is not an exhaustive list. The function will be called just before the built-in no-break passage processing if you're also using thatsee the Config.passages.nobr setting and nobr special tag. The DOM ID of the passage, created from the slugified passage title. Note: 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. To do so, click on the name of your story in its main "story map" view. 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. Terminates the execution of the current iteration of the current <> and begins execution of the next iteration. 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. Removes and returns a random member from the base array. Note: The default cursor is the block element character Right Half Block (U+2590) and it has no default font or color styling. See the HTML and CSS docs for more information. Those that want an expression are fairly straightforward, as you simply supply an expression. 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. Assigns the value on the right-hand side of the operator to the left-hand side. If necessary, you may also use multiple tags by switching from .includes() to .includesAny() in the above example. 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. Deprecated: String values will still be accepted for further releases of v2, however, switching to an array is recommendede.g., the string value, This method has been deprecated and should no longer be used. Returns the processed text of the passage, created from applying nobr tag and image passage processing to its raw text. To enable test mode, use the test option (-t, --test). 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. Expressions are simply units of code that yield values when evaluated. Repeatedly executes its contents after the given delay, inserting any output into the passage in its place. UIBar API. Arithmetic: The expression yields a number valuee.g.. Returns whether both the slot saves and autosave are available and ready. See: Any supported object type may itself contain any supported primitive or object type. Intended for social media links. See the :passagestart event for its replacement. private browsing modes do interfere with this. Returns the number of milliseconds that have passed since the current passage was rendered to the page. See LoadScreen API for more information. Replacement patterns have the format {NAME}e.g., {identity}where NAME is the name of a property within either the l10nStrings object or, in a few cases, an object supplied locally where the string is usedthese instances will be commented. Opens the built-in share dialog, which is populated from the StoryShare passage. Closes the dialog. 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. The player will not be prompted and all unsaved state will be lost. 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. As new moments are added, older moments that exceed the maximum number are expired in order of age, oldest first. Note: . Fullscreen API. For example, if you wanted to ask the user to enter a name, your code may look like this in Harlowe: In SugarCube, you would likely want to use the <> macro instead, and pass $name in as the receiving variable: Harlowe's newer input macros, like (dropdown:) and (cycling-link:) use "bound" variables, which are similar in concept to SugarCube's receiver variables. Creates a text input box, used to modify the value of the variable with the given name, optionally forwarding the player to another passage. Deletes the specified on-save handler, returning true if the handler existed or false if not. Valid collection types are: arrays, generic objects, maps, sets, and strings. True gapless transitions between tracks is not supported. Arrays have many built-in methods and other features, and SugarCube adds many more. Returns a reference to the current jQuery object for chaining. The active passage's tags will be added to its data-tags attribute and classes (see: Passage Conversions). 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. Does not affect script or stylesheet tagged passages, for Twine1/Twee, or the Story JavaScript or Story Stylesheet sections, for Twine2. Randomly selects the given number of unique members from the base array and returns the selected members as a new array. Returns a reference to the current AudioTrack instance for chaining. 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 avoid this problem, it's suggested that you use the separate argument form of the <> macro in Twine2as shown above. Additional timed executions may be chained via <>. Returns whether the engine is processing a turni.e., passage navigation has been triggered. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . Triggered before the modification of the state history. Creates a single-use link that deactivates itself and prepends its contents to its link text when clicked. Calling the State.prng.init() methodformerly History.initPRNG()outside of story initialization will now throw an error. See the Engine API docs for more information. For example, the following will give you a basic crossfade: Determines whether the autosave, if it exists, is automatically loaded upon story startup. The SimpleAudio APIs use events internally for various pieces of functionality. Sets the maximum number of states (moments) to which the history is allowed to grow. Unstows the UI bar, so that it is fully accessible again. Return the named macro definition, or null on failure. Note: Periods of ellipsis () signify data that is generated at compile time. Note: LoadScreen API. Several State API methods have moved to the new Engine API. The $args special variable has been deprecated and should no longer be used. Note: 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. This method is meant to work with clickables created via .ariaClick() and may not work with clickables from other sources. Once unloaded, playback cannot occur until the selected tracks' data is loaded again. Removes classes from the selected element(s). <> 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. Unfortunately, this means that the two objects are incompatible. Note: Use the Edit Story JavaScript story editor menu item for scripts. Sets story $variables and temporary _variables based on the given expression. In addition to the history, there is also the active momenti.e., presentand expired momentsi.e., moments that had been played, but have expired from the history, thus cannot be navigated to. Navigation events allow the execution of JavaScript code at specific points during passage navigation. And feedback from the folks over at the Twine Games Discord Server. Opens the built-in alert dialog, displaying the given message to the player. Go to your Twine1/Twee installation directory and open the. Loss of visibility is defined as when the browser window is either switched to another tab or minimized. There are several predefined group IDs (:all, :looped, :muted, :paused, :playing) and custom IDs may be defined via <>. A set of four hyphen/minus characters (-) that begins a line defines the horizontal rule markup. When used to set a value, returns a reference to the current AudioTrack instance for chaining. This is an estimate calculated by the browser based upon the currently downloaded data and the download rate. Wikifies the given content source(s) and appends the result to the target element(s). Tip: The story history is a collection of moments. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. Returns the value of the story or temporary variable by the given name. When the story is restarted by SugarCube rather than refreshed via the browser, the playthrough session, if any, is not loaded. The autosave is, for the most part, a normal save slot, but with a few special features built in. Call this only after populating the dialog with content. They are defined via the Template API. 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 example, if the name of SugarCube's directory is sugarcube, then the name of the .py file within must be sugarcube.py. Normally, when both link and text arguments are accepted, the order is text then link. Terminates the execution of the current <>. Adds an audio group with the given group ID. Interrupts an in-progress fade of the track, or does nothing if no fade is progressing. An array is just like a pill container except it can only contain one item. The links go to the most recent release versions of each in SugarCube's source code repository. Returns a formatted string, after replacing each format item in the given format string with the text equivalent of the corresponding argument's value. The Config object controls various aspects of SugarCube's behavior. Note: Stops playback of the track and forces it to drop any existing data. The Config.audio.pauseOnFadeToZero setting (default: true) determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). Now, whenever you type <<status>>, Twine will print out all stats as set up within the widget, like for example: Strength: Weak Dexterity: Dextrous . The DOM macros do have a limitation that you should familiarize yourself with. This is a collection of tips, from how-tos to best practices. Tip: To enable test mode from the Stories screen, click on the story's gear menu and select the Test Play menu item. Additionally, SugarCube's normal <> macro does not have an output element associated with it and is not, by default, a single-use link like its Harlowe equivalent. Harlowe has stricter typing than SugarCube, requiring authors to call macros like (str:) or (num:) on variables to change their type. There are three forms: a conditional-only form, a 3-part conditional form, and a range form. In SugarCube, they come in two types: story variables and temporary variables. It is unlikely that you will ever want to disable this setting. 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. Its contents are treated as raw HTML markupi.e., none of SugarCube's special HTML processing is performed. Adds a playlist with the given list ID. All changes within this version are elective changes that you may address at your leisure. This does not reclaim the space reserved for the UI bar. Passage render. Warning: Registers the passage as an initialization passage. Executes its contents if the given conditional expression evaluates to true. Track event triggered when a fade completes normally. SugarCube 1.x - The legacy version . 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. Returns the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. If you want to undo previous moments within the history, rather than return to a passage, see the <> macro. 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. To enable test mode from the story editor/map screen, click on the Test menu item (right side of the bottom bar). Gets or sets the track's volume mute state (default: false). See: Removes the specified key, and its associated value, from the story metadata store. Does not modify the original. Deprecated: For instances where you need to run some pure JavaScript and don't want to waste time performing extra processing on code that has no story or temporary variables or TwineScript operators in it and/or worry about the parser possibly clobbering the code. Returns whether any of the macro's ancestors passed the test implemented by the given filter function. A prototype-less generic object whose properties and values are defined by the Setting.addToggle(), Setting.addList(), and Setting.addRange() methods. SugarCube, like JavaScript, uses dynamic typing. Warning: Note: Used within <> macros. The story's title is part of the story project. When a saved story is loaded, the state loaded from the save replaces the current state. Only the primitives, generic objects, some JavaScript natives (specifically: Array, Date, Map, RegExp, and Set), and DOM node objects are supported by default. See SimpleAudio API for more information. See the Config API docs for more information. As you can see, Harlowe creates a deep copy/clone of its non-primitive data types each time they're modified. Removes event handlers from the track. Returns the string with its first Unicode code point converted to upper case. If you want to change the font or color, then you'll need to change the styling of the macro-type class. Happens at the end of passage navigation. In Twine, you can combine the Set Macro with an If Macro to test is some condition is "true.". Removes and returns the last member from the array, or undefined if the array is empty. Releases the loading screen lock with the given ID. Tip: Returns whether any valid sources were registered. You can set the autosave to save either on every passage or only on certain passages. There is no one size fits all example for either of these methods because an instance's properties, and the data contained therein, are what determine what you need to do. Warning: This setting has been deprecated and should no longer be used. 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). 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. you'll need to call the Setting.save() after having done so. Once unloaded, playback cannot occur until the track's data is loaded again. Removes and returns the first member from the array, or undefined if the array is empty. Help with arrays in sugarcube 2. Registers the passage as a VTT passage. See the .includesAny() method for its replacement. Alternatively, if you simply want the UI bar gone completely and permanently, either using UIBar.destroy() or the StoryInterface special passage may be a better choice. Once the code has been fully executed, the contents of the buffer, if any, will be output. Note: Returns the title of the most recent previous passage whose title does not match that of the active passage or an empty string, if there is no such passage. For accessibility reasons, it's recommended that you wrap each <> and its accompanying text within a element. SugarCube is available in two major versions: the current 2.x series and the legacy 1.x series. The config object has been renamed to Config and some of its properties have also changed. The (execution) context object of the macro's parent, or null if the macro has no parent. Those that do not bundle SugarCube v2: Only the older Twine2.0 series.
