twine 2 sugarcube array twine 2 sugarcube array

Starts playback of the selected tracks and fades them from the specified volume level to 0 (silent) over the specified number of seconds. Note: SugarCube - Motoslave.net Note: Additional timed executions may be chained via <>. Returns whether enough data has been loaded to play the track through to the end without interruption. Upon a successful match, the matching case will have its contents executed. Returns the value associated with the specified key from the story metadata store. You will, very likely, never need to use State.current directly within your code. You may, however, simply use the Test Play From Here context menu item on the Start passage to achieve the same result. Renders the given markup and appends it to the dialog's content area. Generates no output. Note: In SugarCube, they come in two types: story variables and temporary variables. The active passage's name will be added as its ID (see: Passage Conversions). Twine 2 Tutorial: Creating a Basic Inventory - Jezner Blog Used within <> macros. This macro has been deprecated and should no longer be used. 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. See State API for more information. For example: In general, you can group expressions into categories based on what kind of value they yield and/or what side effects they cause. Does not modify the original. When you have a situation where you're using a set of passages as some kind of menu/inventory/etc and it's possible for the player to interact with several of those passages, or even simply the same one multiple times, then returning them to the passage they were at before entering the menu can be problematic as they're possibly several passages removed from that originating passagethus, the <> macro and link constructs like [[Return|previous()]] will not work. Normally, those aren't issues as you should not need to use the result of an expression as an argument terribly often. See <> for more information. Returns the given code string, and optional data chunk, wrapped within the JSON deserialization revive wrapper. Returns a reference to the dialog's content area. Create a save, then edit the code as follows: Running that, you'll see $x is 0 and $y is 1. Attaches fullscreen change event handlers. Only deletes the group itself, does not affect its component tracks. The body of the page. Note: Starts playback of the playlist and fades the currently playing track from the specified volume level to 1 (loudest) over the specified number of seconds. Note: Returns the string with its first Unicode code point converted to upper case. Note: Whenever your story is first started or, for any reason, restartede.g., the browser window/tab was refreshed/reloadedit undergoes its startup sequence. Thus, if you need either to be recoverable, then you'll have to handle that yourself. The :not() group modifier syntax (groupId:not(trackIdList)) allows a group to have some of its tracks excluded from selection. If its return value is truthy, the save is allowed to continue unperturbed. Note: If your content consists of DOM nodes, you'll need to use the Dialog.append() method instead. Furthermore, it is no longer instantiated into the legacy macros objectwhich still exists, so SugarCube-compatible legacy macros will continue to work. NOTE: You do not call this manually, it must be called by the change event handler of an element. SugarCube v2 Documentation - Motoslave.net Calling the State.prng.init() methodformerly History.initPRNG()outside of story initialization will now throw an error. 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. Property attributes, including getters/setters, and symbol properties. Doing so allows interactions with the text to also trigger its <>. In SugarCube you can convert them if you need to. For example, if some story passages were tagged with forest, then styles for those forest passages might look like this: These are SugarCube's built-in stylesheets, in order of load/cascade. Executes its contents and appends the output to the contents of the selected element(s). 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. If you're on Linux, right-click on the file and select Copy. State.current is not a synonym for State.active. Returns the title of the active (present) passage. 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. Essentially, a combination of <> and <>. Performs any required processing before the save data is loadede.g., upgrading out-of-date save data. In use, replacement patterns are replaced recursively, so replacement strings may contain patterns whose replacements contain other patterns. Global event triggered as the last step in opening the dialog when Dialog.open() is called. 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. If you simply want to apply actions to multiple tracks simultaneously, then you want a group instead. For those versions that do, the updates are normally completely elective and may be addressed at your leisure, or not at all. Returns whether an audio track with the given track ID exists. See the Save API docs for more information. A function, which causes the autosave to be updated for each passage where its return value is truthy. 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. To simply add a delay to the dismissal of the loading screen to hide initial flashes of unstyled content (FOUC)e.g., style changes and page reflowsyou do not need to use this API. private browsing modes do interfere with this. Executes its contents and prepends the output to the contents of the selected element(s). An alternative to navigating to passages to create menus, inventories, and the like would be to use the Dialog API. Immediately forwards the player to the passage with the given name. classes) guide for more information. Resets the setting with the given name to its default value. Returns whether any of the given members were found within the array. Arrays have many built-in methods and other features, and SugarCube adds many more. 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. Removes and returns the first member from the array, or undefined if the array is empty. May also be, and often is, used to add additional story UI elements and content to the UI bar. Completely removes the UI bar and all of its associated styles and event handlers. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. StoryMenu, etc. See the Save.onSave.add() method for its replacement. Etc. Returns the first of the macro's ancestors that passed the test implemented by the given filter function or null, if no members pass. Valid values are boolean true, which simply causes the passages' titles to be used, an object, which maps passages' titles to their descriptions, or a function, which should return the passages' description. Returns the string with its first Unicode code point converted to upper case, according to any locale-specific rules. Object Name: SugarCube.State.active.variables [How to find variables and manipulate them for people who don't know how to] Type the object name 'SugarCube.State.active.variable' into the console and press enter. Note: Adds the named property to the settings object and a toggle control for it to the Settings dialog. depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. Returns the total number of filled slots. Valid values are the name of the property being animated, which causes the outgoing passage element to be removed once that transition animation is complete, or an integer delay (in milliseconds), which causes the outgoing passage element to be removed once the delay has expired. Sets the selected tracks' repeating playback state (default: false). The Config.debug setting for more information. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. See Also: Any supported object type may itself contain any supported primitive or object type. When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. Warning: Hides the loading screen, if no other locks exist. Save API. Only when manually modifying the values of settings object properties, outside of the controls, would you need to call this method. Block widgets may access the contents they enclose via the _contents special variable. Returns an AudioRunner instance for the tracks matching the given selector. Divides 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. Thus, a call to UIBar.stow() may also be necessary. SugarCube preserves the state of the story as it's being played in a number of ways to both prevent the loss of progress and allow players to save stories. See <> for more information. classes) revival code and associated data within the revive wrapper, which should be returned from an object instance's .toJSON() method, so that the instance may be properly revived upon deserialization. Note: In practice, you'll probably want to use either line continuations or one of the no-break methods: Config.passages.nobr setting, nobr special tag, <> macro. Returns the number clamped to the specified bounds. Thus, all volume adjustments are ignored by the device, though muting should work normally. See SimpleAudio API for more information. Track descriptor objects come in two forms and should have some of the noted properties: Deletes the playlist with the given list ID. Only deletes the groups themselves, does not affect their component tracks. Opens the built-in jump to dialog, which is populated via the bookmark tag. Audio tracks encapsulate and provide a consistent interface to an audio resource. Warning: Note: The Non-generic object types (a.k.a. See Localization for more information. Happens before the end of passage navigation. Gets or sets the track's current time in seconds. Begins playback of the playlist or, failing that, sets the playlist to begin playback as soon as the player has interacted with the document. Note: Performs any required processing before the save data is saved. Note: The capitalization and punctuation used within the default replacement strings is deliberate, especially within the error and warning strings. 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: Gets or sets the track's volume mute state (default: false). Warning: Occasionally, however, macros will need the name of a variable rather than its valuee.g., data input macros like <>so that they may modify the variable. The sigil must be a dollar sign ($) for story variables or an underscore (_) for temporary variables. Returns the bottommost (least recent) moment from the full in-play history (past + future). Probably most useful when paired with <>. To actually affect multiple tracks and/or groups, see the SimpleAudio.select() method. Does not modify the original. This macro has been deprecated and should no longer be used. Creates a cycling link, used to modify the value of the variable with the given name. Deprecated: Sets the starting passage, the very first passage that will be displayed. Warning: Removes event handlers from the selected tracks. Warning: Note: Starts playback of the track and fades it between the specified starting and destination volume levels over the specified number of seconds. Determines whether alternate passage descriptions are used by the Saves and Jump To menusby default an excerpt from the passage is used. Deprecated: If its return value is truthy, the override succeeds and that value is used as the new destination of the navigation. Because of the additional HTML elements added by the debug views, some nested markup and selectors may be broken. The DOM ID of the passage, created from the slugified passage title. Its contents are treated as raw HTML markupi.e., none of SugarCube's special HTML processing is performed. Displays the loading screen, if necessary. Returns whether an audio group with the given group ID exists. Global event triggered as the first step in closing the dialog when Dialog.close() is called. Yes it is possible. Local event triggered on the typing wrapper when the typing of a section starts. This guide will detail how these features work. While there are no custom properties, the event is fired from the dialog's body, thus the target property will refer to its body elementi.e., #ui-dialog-body. In the Add a New Format tab, paste in the file path to format.js and click the green Add button. Shows the UI bar. Tip: Engine API. The number of moments contained within the story history is, generally, limited, via the Config.history.maxStates setting. To enable test mode while starting at a specific passage, right-click on a passage and select the Test Play From Here context menu item. Returns the number of moments within the past in-play history (past only). Sets the selected tracks' current time in seconds. Alias for jQuery, by default. Returns how much remains of the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. Returns whether the engine is rendering the incoming passage. Finally, one of three things happen (in order): the existing playthrough session is restored, if it exists, else the autosave is loaded, if it exists and is configured to do so, else the starting passage is run. Instead, use either the built-in functions random() & randomFloat() or the State.random() method, if you need direct access to the PRNGsince it returns a call to either Math.random() or the seedable PRNG, as appropriate. The core of what it does is simply to wrap a call to, This method has been deprecated in favor of the, This method has been deprecated and should no longer be used. The typed text has no default styling. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. As a basic working definition, non-generic object typesa.k.a. Config.saves.autosave setting, Config.saves.autoload setting, and Save API: Autosave. Returns a reference to the current jQuery object for chaining. Return the named macro definition, or null on failure. Prior to SugarCube v2.10.0, the strings localization object was named strings. For example, if a value "is" strictly the . Select "Change Story Format" and check the box next to "Sugarcube." Download PDF version: Variables and Programming in Twine Caches an audio track for use by the other audio macros. 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. In SugarCube, you instead open and close the <> macro itself: Some macros in Harlowe and SugarCube share a name but work a bit differently. You would do well to keep your translations similar when possible. Yield the single line in the final output: An exclamation point (!) Use the Edit Story Stylesheet story editor menu item for styles. Returns the AudioList instance with the given list ID, or null on failure. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. Roughly equivalent to the :passagestart event. 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. Returns whether playback of the playlist has been stopped. SugarCube 1.x - The legacy version . An array is a container that holds things. Arithmetic: The expression yields a number valuee.g.. Widgets allow you to create macros by using the standard macros and markup that you use normally within your story. May be terminated by a <> macro. Returns whether fullscreen mode is currently active. Used for pre-passage-display tasks, like redoing dynamic changes (happens before the rendering of each passage). Returns the total number (count) of played turns currently in effecti.e., the number of played moments up to the present moment; future (rewound/undone) moments are not included within the total. System events allow the execution of JavaScript code at specific points during story startup and teardown. Warning: The most common way to resolve this arbitrarily long return issue is to use a bit of JavaScript to record the last non-menu passage the player visited into a story variable and then to create a link with that. Several things occur each and every time startup happens, regardless of whether or not a playthrough session will be restored, an autosave loaded, or the starting passage run. State API. Meaning that when you pass a variable as an argument, its value is passed to the macro rather than its name. Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Twine 2 Editor Twine 2 Editor Story Listing Passages View Passages Story Formats Getting . Once a track has been unloaded, playback cannot occur until it is reloaded. Creates a listbox, used to modify the value of the variable with the given name. Warning: Note: This is not an exhaustive list. The starting passage, the first passage displayed. 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. Dialog events allow the execution of JavaScript code at specific points during the opening and closing of dialogs. Setting API. Does not modify the original. The loading process is as described in SimpleAudio.load(). For example: If you run the above, you'll see $x is 0. 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. Sometimes there are breaking changes, however, and these must be addressed immediately. Note: Circular references. Returns a reference to the current AudioRunner instance for chaining. If it encounters an unrecoverable problem during its processing, it may throw an exception containing an error message; the message will be displayed to the player and loading of the save will be terminated. Returns whether the UI bar is currently hidden. Hides the UI bar. 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. Used within <> macros. Triggered at the end of passage navigation. Sets the value of the story or temporary variable by the given name. Note: See the Test Mode guide for more information. It is passed an abbreviated version of the associated passage's Passage instancecontaining only the tags, text, and title properties. Twine1/Twee: Registers the passage as a CSS stylesheet, which is loaded during startup. Pauses playback of the playlist and, if they're not already in the process of loading, forces its tracks to drop any existing data and begin loading. The .hasData() method is generally more useful. Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. Essentially, a combination of <> and <>. Note: This function is finicky, however. Widgets should always be defined within a widget-tagged passageany widgets that are not may be lost on page reloadand you may use as few or as many such passages as you desire. This setting has been deprecated and should no longer be used. Making a new story To make a new story, press the button labelled + Story. Passage API. To resolve these instances, you will need to quote the name of the variablei.e., instead of passing $pie as normal, you'd pass "$pie". 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. As all special passage populated sections are updated it is recommended that UIBar.update() be used sparingly. Audio runners are useful for performing actions on multiple tracks at once. To do so, click on the name of your story in its main "story map" view. 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. The UISystem API object has been split into two APIs Dialog and UI, and some of its methods have also changed. StoryInit is run, as always. Story API. Does not modify the original. AudioTrack API, AudioRunner API, and AudioList API. Additional elements, aside from the #passages element, may include either the data-init-passage or data-passage content attribute, whose value is the name of the passage used to populate the elementthe passage will be processed as normal, meaning that markup and macros will work as expected. If you're simply looking to download ready-to-use localizations, see SugarCube's website (under Downloads > Localizations). Tag it with the appropriate media passage special tag, and only that tagsee below. Used for post-passage-display tasks, like redoing dynamic changes (happens after the rendering and display of each passage). See the Macro API docs for more information. Similarly, if the directory is sugarcube-2, then the name of the .py file within must be sugarcube-2.py. See Also: Expressions are simply units of code that yield values when evaluated. Wikifies the given content source(s) and appends the result to the target element(s). Determines whether the audio subsystem attempts to preload track metadatameaning information about the track (e.g., duration), not its audio frames. Template API. Twee 3 Language Tools - Visual Studio Marketplace If you need a random member from an array-like object, use the Array.from() method to convert it to an array, then use .random(). 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. Returns whether, at least, the track's metadata has been loaded. Zorkish Sugarcube 6. classesare instantiable objects whose own prototype is not Objecte.g., Array is a native non-generic object type. Executes its contents and outputs the result, after removing leading/trailing newlines and replacing all remaining sequences of newlines with single spaces. A Quick Twine (2.2+) Tutorial: Computational Approaches to Narrative Returns the playlist's current time in seconds, or NaN if no metadata exists. The def and ndef operators have very low precedence, so it is strongly recommended that if you mix them with other operators, that you wrap them in parenthesese.g., (def $style) and ($style is "girly"). Tip: For normal projects, authors are encouraged to continue to use the StoryInit special named passage. The new l10nStrings object has a simpler, flatter, set of properties and better support for replacement strings. Returns whether the autosave is available and ready. The StoryInit special passage is normally the best place to set up playlists. If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. This series is intended for. Returns whether the given slot is filled. Function behavior is immutable. If the autosave cannot be loaded, for any reason, then the start passage is loaded instead. Note: This should not be done lightly if your audio sources are on the network, as it forces players to begin downloading them. .one() in the jQuery API docs for more information. Happens before the modification of the state history. Pauses playback of the track and, if it's not already in the process of loading, forces it to drop any existing data and begin loading. The argument string after converting all TwineScript syntax elements into their native JavaScript counterparts. SugarCube is a free (gratis and libre) story format for Twine/Twee. Manages the Settings dialog and settings object. 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. Note: Removes the audio group with the given ID. Note: Note: Next, the StoryInit special passage is processed. Returns whether all of the given members were found within the array. Gets or sets the mute state for the master volume (default: false). Provides access to browsers' fullscreen functionality. Track event triggered when a fade completes normally. 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. Returns a reference to the active (present) story variables store (equivalent to: State.variables). Returns a new array filled with all Passage objects that contain the given property, whose value matches the given search value, or an empty array, if no matches are made. Due to how the Twine2 automatic passage creation feature currently works, using the link markup form will cause a passage named $return to be created that will need to be deleted. Displays the loading screen until all currently registered audio tracks have either loaded to a playable state or aborted loading due to errors. Several State API methods have moved to the new Engine API. The audio subsystem is based upon the HTML Media Elements APIs and comes with some built-in limitations: Pauses playback of all currently registered tracks and, if they're not already in the process of loading, force them to drop any existing data and begin loading.
