May also be, and often is, used to add additional story UI elements and content to the UI bar. Local event triggered on the typing wrapper when the typing of a section stops. Deletes the specified on-load handler, returning true if the handler existed or false if not. A fullscreen options object should have some of the following properties: Note: Sets the starting passage, the very first passage that will be displayed. Warning: This is not an exhaustive list. Call this only after populating the dialog with content. You'll likely use story variables most often throughout your projectthough, temporary variables are perfect candidates for things like loop variables, if you're using the <> macro. 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. 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. 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. Create a save, then edit the code as follows: Running that, you'll see $x is 0 and $y is 1. Starts playback of the selected tracks and fades them between the specified starting and destination volume levels over the specified number of seconds. In this case, once we assign $wumpus a room, we can delete that room from our $roomlist. Note: The debug views may be toggled via the Views button. Returns the number of moments within the past in-play history (past only). If no autosave exists, then the starting passage is rendered. Warning: Only deletes the group itself, does not affect its component tracks. If you need to check for multiple passages, the hasVisited() story function will likely be more convenient to use. Navigating back to a previous passage, for whatever reason, can be problematic. Warning: Because replacement is recursive, care must be taken to ensure infinite loops are not createdthe system will detect an infinite loop and throw an error. A right angle bracket (>) that begins a line defines the blockquote markup. See Macro API for more information. If you want to change the font, color, or character, then you'll need to change the styling of the :after pseudo-element of the macro-type-cursor class. Twine2: Not special. Note: If omitted, the story title will be used instead. An array is a container that holds things. 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. To update the value associated with a key, simply set it again. Audio runners are useful for performing actions on multiple tracks at once. The StoryInit special passage is normally the best place to set up playlists. 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. Normally, there will be only one such passage per turn, however, during passage navigation there may briefly be twothe incoming (a.k.a. It is further strongly suggested that you provide that same custom user namespace when removing them. Evaluates the given expression and compares it to the value(s) within its <> children. Since it is possible to navigate the historyi.e., move backward and forward though the moments within the historyit may contain both past momentsi.e., moments that have been playedand future momentsi.e., moments that had been played, but have been rewound/undone, yet are still available to be restored. Deprecated: Releases the loading screen lock with the given ID. This is a reference for localizing SugarCube's default UI text, in general, and its l10nStrings object specifically. Executes its contents and appends the output to the contents of the selected element(s). Links From Variables in Twine With Sugarcube - Instructables Skips ahead to the next track in the playlist, if any. If multiple passage titles are given, returns the lowest count (which can be -1). 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. If your content consists of DOM nodes, you'll need to use the Dialog.append() method instead. You may not remove the predefined group IDs (:all, :looped, :muted, :paused, :playing) or the :not group modifier. Making custom non-generic object types fully compatible requires that two methods be added to their prototype, .clone() and .toJSON(), to support cloningi.e., deep copyinginstances of the type. Note: Note: May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. Silently executes its contents as pure JavaScript codei.e., it performs no story or temporary variable substitution or TwineScript operator processing. Selects all internal link elements within the passage element whose passages are within the in-play story historyi.e., passages the player has been to before. Provides access to browsers' fullscreen functionality. Passage API. A Twine 2 proofing format that renders nodes as a GraphViz (dot) graph. See the Localization guide for more information. Creates a new widget macro (henceforth, widget) with the given name. Essentially, a combination of <> and <>. Setting API method calls must be placed within your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) or settings will not function correctly. 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. If SugarCube is reloaded by one of its own built-in restart methods, then the session is. 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. Return the named macro definition, or null on failure. Expired moments are recorded in a separate expired collection and can no longer be navigated to. Non-generic object types (a.k.a. The StoryInit special passage is normally the best place to set up groups. Determines whether saving is allowed within the current context. Once unloaded, playback cannot occur until the track's data is loaded again. The Top 14 Javascript Twine2 Open Source Projects Note: Begins playback of the track or, failing that, sets the track to begin playback as soon as the player has interacted with the document. If you plan on using interactive macros within a loop you will likely need to use the. If you simply want to apply actions to multiple tracks simultaneously, then you want a group instead. To ensure backwards compatibility of existing strings objects, if one exists within a project's scripts, the older object is mapped to the new l10nStrings object. Note: However, this means that extra care must be taken when writing them to ensure that unwanted whitespace is not created within the final output. Renders the selected passage into the target element, replacing any existing content, and returns the element. Note: Thus, it is only truly useful if you plan to upgrade out-of-date saves via a Config.saves.onLoad callback. Note: May eat line-breaks in certain situations. 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. Returns the title of the passage associated with the active (present) moment. 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. The SaveSystem API object has been renamed to Save and several of its methods have also changed, for better consistency with the other APIs. Deprecated: Returns whether an audio track with the given track ID exists. Determines whether the audio subsystem attempts to preload track metadatameaning information about the track (e.g., duration), not its audio frames. 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. A side effect simply means that the evaluation of the expression modifies some state. There are cases, however, where things get a bit more complicated, namely: instances where you need to pass the name of a variable as an argument, rather than its value, and those where you want to pass the result of an expression as argument. The handlers is passed two parameters, the save object to be processed and save operation details object. Note: Warning: There are many differences between Harlowe and SugarCube, this guide will document some of the most critical you will need to account for if you're coming to SugarCube from a background in Harlowe. Note: Outputs a string representation of the result of the given expression. The text of a container macro parsed into discrete payload objects by tag. 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. Note: Function behavior is immutable. 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. The names of both story and temporary variables have a certain format that they must followwhich signifies that they are variables and not some other kind of data. The :not() group modifier syntax (groupId:not(trackIdList)) allows a group to have some of its tracks excluded from selection. This setting exists to prevent a misconfigured loop from making the browser unresponsive. Intended for social media links. Registers the passage into the Jump To menu. StoryInit is run, as always. Note: The SimpleAudio APIs use events internally for various pieces of functionality. Global event triggered as the first step in opening the dialog when Dialog.open() is called. Immediately forwards the player to the passage with the given name. Property attributes, including getters/setters, and symbol properties. See the Dialog API docs for more information. 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. Deletes all currently registered on-load handlers. Warning: Returns whether a playlist with the given list ID exists. classes), Updating to any version 2.30.0 from a lesser version, Updating to any version 2.29.0 from a lesser version, Updating to any version 2.28.0 from a lesser version, Updating to any version 2.20.0 from a lesser version, Updating to any version 2.15.0 from a lesser version, Updating to any version 2.10.0 from a lesser version, Updating to any version 2.8.0 from a lesser version, Updating to any version 2.5.0 from a lesser version, Updating to any version 2.0.0 from a lesser version, embedded image passage (Twine1 & Tweego only), https://cdn.jsdelivr.net/gh/tmedwards/sugarcube-2/dist/format.js. Triggered before the modification of the state history. classes) guide for more information. See the :passagerender event for its replacement. See Dialog API for more information. There are ways to turn webapps into apps for mobile phones and Windows/Linux etc, but it's still running in a web browser under the hood. Gets or sets the track's volume mute state (default: false). As you can see, Harlowe creates a deep copy/clone of its non-primitive data types each time they're modified. This macro is functionally identical to <>, save that it also encodes HTML special characters in the output. private browsing modes do interfere with this. Gets or sets the master volume level (default: 1). In SugarCube, you instead open and close the <> macro itself: Some macros in Harlowe and SugarCube share a name but work a bit differently. Returns a reference to the UIBar object for chaining. Repeatedly executes its contents after the given delay, inserting any output into the passage in its place. Note: At the very least you will need to specify a .passage-out style that defines the transition's end state. They are defined via the Template API. The active passage's tags will be added to its data-tags attribute (see: Passage Conversions). See Also: Prepends one or more members to the beginning of the base array and returns its new length. There are many ways to use and interact with variables. depending on the age of your browser, you may also see a list of all current variables when interacting with the Add field. Note: Returns whether a fade is in-progress on the currently playing track. Dialog events allow the execution of JavaScript code at specific points during the opening and closing of dialogs. Creates a link that navigates forward to a previously visited passage. Track event triggered when a fade completes normally. To enable test mode from the Stories screen, click on the story's gear menu and select the Test Play menu item. When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. Note: Moves backward one moment within the full history (past + future), if possible, activating and showing the moment moved to. This is a reference on how to update existing SugarCube code to work with newer versions of SugarCube. Adds a playlist with the given list ID. Stops playback of all currently registered tracks and force them to drop any existing data. Returns whether, at least, the track's metadata has been loaded. Deprecated: This does not alter the volume level. . Unstows the UI bar, so that it is fully accessible again. See the .includes() method for its replacement. It consists of one to six exclamation points, each additional one beyond the first signifying a lesser heading. See the Config API docs for more information. See Also: See the :passageinit event for its replacement. Math.random() is no longer replaced by the integrated seedable PRNG when State.prng.init() is called. Your project's JavaScript section (Twine2: the Story JavaScript; Twine1/Twee: a script-tagged passage) is normally the best place to call importStyles(). 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. Returns a reference to the UIBar object for chaining. Feel free to add your own if that makes localization easiere.g., for gender, plurals, and whatnot. Resets the setting with the given name to its default value. 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. See Also: It is strongly recommended that you use only one stylesheet passage. First, the CSS, JavaScript, and Widget sections are processed. The data-init-passage attribute causes the element to be updated once at initialization, while the data-passage attribute causes the element to be updated upon each passage navigation. The story's title is part of the story project. Audio, image, video, and VTT passages are supported. Macro context objects contain the following data and method properties. Displays the loading screen, if necessary. Then close the dialog box. Tag it with the appropriate media passage special tag, and only that tagsee below. As all special passage populated sections are updated it is recommended that UIBar.update() be used sparingly. Instead of storing any "static" data (data which won't change during the entire game, e.g. 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. Attaches event handlers to the track. Gets or sets the track's volume level (default: 1). For standard browser/DOM events, see the Event reference @MDN. Variables - Twine Cookbook Loop variables are perfect candidates for the use of temporary variablese.g.. To ensure that line-breaks end up where you want them, or not, extra care may be required. Note: Note: Saving the story records the story's state up until the last moment that was created. Creates a multiline text input block, used to modify the value of the variable with the given name. Determines whether saving to disk is enabled on mobile devicesi.e., smartphones, tablets, etc. Note: Calling the State.prng.init() methodformerly History.initPRNG()outside of story initialization will now throw an error. Anything from a number to a series of characters can be stored in a variable. Code like <> seems to have no effect because the startup state is replaced by the of the incoming state, but they are still executed by the engine. Registers the passage as an image passage. Additionally. Deprecated: The callback is invoked each time a save is requested. For example, if the name of SugarCube's directory is sugarcube, then the name of the .py file within must be sugarcube.py. Ideally, if you need to update UI bar content outside of the normal passage navigation update, then you should update only the specific areas you need to rather than the entire UI bar. Deprecated: Executes its contents after the given delay, inserting any output into the passage in its place. When used to set the loop state, returns a reference to the current AudioList instance for chaining. Returns the number of times that the given member was found within the array, starting the search at position. Creates a checkbox, used to modify the value of the variable with the given name. Save API. Shorthand for jQuery's .one() method applied to the audio element. Note: A Total Beginner's Guide to Twine 2.0 - Adam Hammond This section offers a list of SugarCube-specific events, triggered at various points during story operation. Determines whether alternate passage descriptions are used by the Saves and Jump To menusby default an excerpt from the passage is used. In SugarCube you can convert them if you need to. older versions of Twine2 used a icon for the same purpose. In that case, unless you need to dynamically determine the destination passage within the <> body, <> is unnecessary as <> already includes the ability to forward the player. However, due to a historical artifact, the arguments for the separate argument form of <> are in the reverse order (link then text). 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. Warning: Due to how SugarCube stores the state history a few constructs are not supported within story variables. Opens the dialog. See the <> macro for its replacement. Track descriptor objects come in two forms and should have some of the noted properties: Deletes the playlist with the given list ID. Note: Load and integrate external CSS stylesheets. Updates all sections of the UI bar that are populated by special passagese.g., StoryBanner, StoryCaption, StoryMenu, etc. Due to a flaw in the current release of Twine1/Twee (v1.4.2), if you rename the directory included in the archive (or simply copy its contents to your current SugarCube v2 install), then you must ensure that the file with the extension .py (the story format's custom Twine1 Header class file) within is named the same as the directoryi.e., the name of the directory and .py file must match. Additionally, see the tagged stylesheet warning. Note: 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.
