June 2017 in Help! Load and integrate external CSS stylesheets. Deletes the specified on-load handler, returning true if the handler existed or false if not. You will also need some CSS styles to make this workexamples given below. Functionally identical to <>. Immediately forwards the player to the passage with the given name. Warning: A format item has the syntax {index[,alignment]}, square-brackets denoting optional elements. Deprecated: May be terminated by a <> macro. Determines whether the <> macro types out content on previously visited passages or simply outputs it immediately. If you need to check for multiple passages, the hasVisited() story function will likely be more convenient to use. When used to set the mute state, returns a reference to the current AudioTrack instance for chaining. Harlowe is the default style for Twine 2.0 and uses a syntax that is different than Sugarcube. Setting API. Twine2: Not special. Hides the UI bar. If you need them, then you'll need to use a class or similar non-generic object. Does not affect script or stylesheet tagged passages, for Twine1/Twee, or the Story JavaScript or Story Stylesheet sections, for Twine2. If you simply want to empty the selected element(s), not remove them outright, you should use an empty <> macro instead. A Total Beginner's Guide to Twine 2.0 - Adam Hammond Silently executes its contents when the incoming passage is done rendering and has been added to the page. See Save API for more information. SimpleAudio API, AudioTrack API, and AudioList API. Or, if you use the start passage as real part of your story and allow the player to reenter it, rather than just as the initial landing/cover page, then you may wish to only disallow saving on the start passage the very first time it's displayedi.e., at story startup. 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. Passage end. 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. 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. 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 enable test mode from the Stories screen, click on the story's gear menu and select the Test Play menu item. The previous state is completely lostthe new state is not added to or combined with the current state, instead it replaces it in its entirety. Returns the size of the story metadata storei.e., the number of stored pairs. Allows custom processing of passage text. Returns a reference to the current AudioRunner instance for chaining. 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. (Help) Error: UI is not defined when trying to create a save/load button SugarCube 2 Hi, i'm pretty new to using twine / sugarcube, so i do apologise for the noob question. Returns the string with its first Unicode code point converted to upper case. Silently executes its contents as pure JavaScript codei.e., it performs no story or temporary variable substitution or TwineScript operator processing. May also be, and often is, used to add additional story UI elements and content to the UI bar. Generates no output. Note: Returns the first member from the array. Returns whether there are any filled slots. The SaveSystem API object has been renamed to Save and several of its methods have also changed, for better consistency with the other APIs. 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. Note: The easiest way to understand this is to look at what happens when you make some changes to StoryInit and then load a saved story from before those changes were made. Returns whether any of the macro's ancestors passed the test implemented by the given filter function. Warning: This method has been deprecated and should no longer be used. See the Engine API docs for more information. Returns the number of times that the given member was found within the array, starting the search at position. SugarCube v2 Documentation - Motoslave.net The Non-generic object types (a.k.a. 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. The callback is invoked each time a save is requested. Returns whether the engine is rendering the incoming passage. In Harlowe, the same operation will yield an error: You must convert the values to the same type in Harlowe. Due to how SugarCube stores the state history a few constructs are not supported within story variables. Request that the browser enter fullscreen mode. Triggered after the displayi.e., outputof the incoming passage. In SugarCube, they come in two types: story variables and temporary variables. Triggered before the rendering of the incoming passage. . Tip: To delete a watch, click the button next to its name in the watch panel. Warning: All changes within this version are elective changes that you may address at your leisure. 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. If no name is given, resets all settings. May eat line-breaks in certain situations. This method will not return "code" passagesi.e., script, stylesheet, and widget passages. Local event triggered on the typing wrapper when the typing of a section stops. Normally, the values of its properties are automatically managed by their associated Settings dialog control. Skips ahead to the next track in the playlist, if any. This does not alter the volume level. If you want to undo previous moments within the history, rather than return to a passage, see the <> macro. See LoadScreen API for more information. Normally, when both link and text arguments are accepted, the order is text then link. Toggles classes on the selected element(s)i.e., adding them if they don't exist, removing them if they do. This is an estimate calculated by the browser based upon the currently downloaded data and the download rate. Thus, there are some potential pitfalls to consider: Creates a button that silently executes its contents when clicked, optionally 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. This means that non-widget uses of these special variable are completely safe, though this does have the effect that uses external to widgets are inaccessible within them unless passed in as arguments. Note: Concatenates one or more unique members to the end of the base array and returns the result as a new array. Gets or sets the mute state for the master volume (default: false). Note: Returns whether the full in-play history (past + future) is empty. A fullscreen options object should have some of the following properties: Note: Warning: Controls the playback of audio tracks, which must be set up via <>. Furthermore, it is no longer instantiated into the legacy state objectwhich still exists, so legacy code will continue to work. If multiple passage titles are given, returns the lowest count (which can be -1). If the autosave cannot be loaded, for any reason, then the start passage is loaded instead. In SugarCube, you instead open and close the <> macro itself: Some macros in Harlowe and SugarCube share a name but work a bit differently. The State.display() methodformerly state.display()is no longer overridable, meaning it cannot be wrappede.g., the "StoryRegions" 3rd-party add-ons do this. See the Save.onLoad.add() method for its replacement. The load and playback states of tracks are not currently recorded within the active play session or saves. This setting exists to prevent a misconfigured loop from making the browser unresponsive. 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. Assignment: The expression causes an assignment to occure.g., A backquote is also known as a grave and is often paired with the tilde (. 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. Data stored there won't take up space in the game history, but will be accessible both from Twine and . Note: TypeScript bindings for SugarCube APIs can found as the Definitely Typed package: @types/twine-sugarcube. Sets the specified key and value within the story metadata store, which causes them to persist over story and browser restartsn.b. By default, it simply returns non-deterministic results from Math.random(), however, when the seedable PRNG has been enabled, via State.prng.init(), it returns deterministic results from the seeded PRNG instead. This method has been deprecated and should no longer be used. Triggered at the end of passage navigation. When used to set the loop state, returns a reference to the current AudioTrack instance for chaining. Harlowe's implementation of the (goto:) macro terminates the rendering passage. In versions of SugarCube v2.23.0, the debugging interface offers additional tools, namely variable watches and arbitrary history navigation. Used to populate the story's banner area in the UI bar (element ID: story-banner). Note: Returns how much remains of the playlist's total playtime in seconds, Infinity if it contains any streams, or NaN if no metadata exists. Does not flag other assignment operators. Aside from general syntax, SugarCube macros do not use hooks, separate arguments differently, and don't allow other macros to be passed as arguments. The default foreground and background colors are set here. Registers the passage into the Jump To menu. If you have a property that uses an array of values, you will be able to use the various "tag" functions to . In SugarCube, discreet arguments passed to a macro are separated by spaces instead of commas. Determines whether the story's history controls (Backward, Jump To, & Forward buttons) are enabled within the UI bar. Warning: Global event triggered as the first step in opening the dialog when Dialog.open() is called. 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. 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. Outputs a string representation of the result of the given expression. 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. Returns whether any moments with the given title exist within the past in-play history (past only). 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. 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. Whenever your story is first started or, for any reason, restartede.g., the browser window/tab was refreshed/reloadedit undergoes its startup sequence. To delete all current watches, click the button. 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. Removes fullscreen change event handlers. Does not modify the original. Because of the additional HTML elements added by the debug views, some nested markup and selectors may be broken. If setting a background image via the background shorthand property, then you should also specify a background-color value with it or include a separate background-color property after the background property. Sets the story's title. 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"). Returns a reference to the current AudioRunner instance for chaining. postdisplay tasks have been deprecated and should no longer be used. 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. Sets the story's subtitle in the UI bar (element ID: story-subtitle). Returns the bottommost (least recent) moment from the full in-play history (past + future). Its return value should be the post-processed text. 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. See the .includesAny() method for its replacement. Happens before the modification of the state history. Performs any required processing before the save data is loadede.g., upgrading out-of-date save data. Returns how much remains of the track's total playtime in seconds, Infinity for a stream, or NaN if no metadata exists. The handler is passed one parameter, the save object to be processed. Using <> to automatically forward players from one passage to another with no input from them will both create junk moments within the story history and make it extremely difficult for players to navigate the history. Starts playback of the track and fades it between the specified starting and destination volume levels over the specified number of seconds. Collects tracks, which must be set up via <>, into a playlist via its <> children. It is strongly recommended that you do not place background properties on the html element in addition to the body element as this can cause background jitter in Internet Explorer when scrolling outside of fullscreen mode. This section offers a list of SugarCube-specific events, triggered at various points during story operation. There are two primary branches of Twine2 as far as SugarCube is concerned: Regardless of the version of Twine2 you're using, follow these instructions to install a local copy of SugarCube v2: Note: Removes and returns the first member from the array, or undefined if the array is empty. 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. It is not a mechanism for moving data between stories. SugarCube does not have any equivalents to Harlowe's (click:) family of macros. Returns a new array consisting of the flattened source array. Widgets allow you to create macros by using the standard macros and markup that you use normally within your story. Note: Object that authors/developers may use to set up various bits of static data. They serve the same basic purpose as the <> macro, but are run each time passage navigation occurs. All changes within this version are breaking changes that you must address immediately. Adds an audio group with the given group ID. This means that some code points may span multiple code unitse.g., the character is one code point, but two code units. Determines whether saving to disk is enabled on mobile devicesi.e., smartphones, tablets, etc. It consists of one to six exclamation points, each additional one beyond the first signifying a lesser heading. 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. This is a collection of tips, from how-tos to best practices. SimpleAudio API, AudioTrack API, and AudioRunner API. Causes any output generated within its body to be discarded, except for errors (which will be displayed). See the State.prng.init() method for its replacement. 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. Returns the number of currently registered on-save handlers. Adds the named property to the settings object and a toggle control for it to the Settings dialog.
