Returns a random member from the base array. See: The maximum number of loop iterations in the conditional forms is not unlimited by default, however, it is configurable. Returns a reference to the current AudioRunner instance for chaining. Executes its contents if the given conditional expression evaluates to true. Macro handlers are called with no arguments, but with their this set to a macro (execution) context object. Returns the AudioList instance with the given list ID, or null on failure. This setting exists to prevent a misconfigured loop from making the browser unresponsive. Note: Request that the browser enter fullscreen mode. 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. Prepends one or more unique members to the beginning of the base array and returns its new length. The autosave feature is occasionally confused with the playthrough session feature, but they are in fact distinct systems. First of all, many thanks for your advise. Triggered after the displayi.e., outputof the incoming passage. Saving the story records the story's state up until the last moment that was created. This method has been deprecated and should no longer be used. 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"). Macro API. When SugarCube is reloaded by the browser, it checks if a playthrough session exists and loads it to prevent any inadvertent loss of progress. You will also need to specify a .link-visited style that defines the properties visited links should have. Creates a cycling link, used to modify the value of the variable with the given name. Returns a formatted string, after replacing each format item in the given format string with the text equivalent of the corresponding argument's value. Returns the current moment from the full in-play history (past + future), which is the pre-play version of the active moment. An asterisk (*) or number sign (#) that begins a line defines a member of the unordered or ordered list markup, respectively. Normally, those aren't issues as you should not need to use the result of an expression as an argument terribly often. To update the value associated with a key, simply set it again. 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. While it renders content just as any other passage does, instead of displaying the rendered output as-is, it sifts through the output and builds its menu from the generated links contained therein. 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. Normally, when both link and text arguments are accepted, the order is text then link. Warning: By default, it uses Math.random() as its source of (non-deterministic) randomness, however, when the seedable PRNG has been enabled, via State.prng.init(), it uses that (deterministic) seeded PRNG instead. 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. What I want to do Assignment: The expression causes an assignment to occure.g., A backquote is also known as a grave and is often paired with the tilde (. Attaches event handlers to the selected tracks. Returns an array of the story metadata store's key/value pairs as [key, value] arrays. The SugarCube algorithm instead of identifying frequencies or bands of audio with problems looks for events in the time domain and then corrects the audio to remove them by interpolating the slope of the preceding audio. A range definition object should have some of the following properties: Note: The core of what it does is simply to wrap a call to Dialog.open() within a call to .ariaClick(), which can be done directly and with greater flexibility. The Config.audio.pauseOnFadeToZero setting (default: true) controls whether tracks that have been faded to 0 volume (silent) are automatically paused. Determines whether the autosave is created/updated when passages are displayed. Because the custom style markup uses the same tokens to begin and end the markup, it cannot be nested within itself. Warning: <> 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. Acquires a loading screen lock and returns its ID. Groups are useful for applying actions to multiple tracks simultaneously and/or excluding the included tracks from a larger set when applying actions. 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. classes) guide for more information. This is only really useful within pure JavaScript code, as within TwineScript you may simply access story variables natively. Deletes the specified on-load handler, returning true if the handler existed or false if not. If multiple passage titles are given, returns the lowest count (which can be -1). If the autosave exists and the story is configured to automatically load it, then the autosave is loaded and the state is replaced by the autosave's state and the active passage is rendered, just as if the user had loaded any other save. Sets the maximum number of states (moments) to which the history is allowed to grow. Returns whether the operation was successful. The $args special variable has been deprecated and should no longer be used. Twine2: Not special. If you want to undo previous moments within the history, rather than return to a passage, see the <> macro. The Macros API object has been renamed to Macro and several of its methods have also changed, for better consistency with the other APIs. To enable test mode from the Stories screen, click on the story's gear menu and select the Test Story menu item. Thanks for submitting an issue. .on() in the jQuery API docs for more information. Only deletes the groups themselves, does not affect their component tracks. To pass expressions or the results of functions to macros as an argument, you must wrap the expression in backquotes (`). This temporary playthrough session is intended to prevent players from losing data. Immediately forwards the player to the passage with the given name. Note: Removes all of the members at the given indices from the array and returns a new array containing the removed members. You signed in with another tab or window. Elements that include either a data-init-passage or data-passage content attribute should not themselves contain additional elementssince such elements' contents are replaced each turn via their associated passage, any child elements would be lost. Note: Note: Does not modify the original. I really hope there is no other post similar; if so, my apologies for asking again. What I want to do with those images is explained in the following links: How To Create an Image Magnifier Glass (w3schools.com), How To Create a Tab Image Gallery (w3schools.com). LoadScreen API. Prepends one or more members to the beginning of the base array and returns its new length. Some users have the false impression that StoryInit is not run when the story is restarted when the playthrough session is restored or autosave is loaded. See UI API for more information. Chrome just open the game, press F12 and go to the console where you can. This means that some code points may span multiple code unitse.g., the emoji is one code point, but two code units. Determines whether the audio subsystem attempts to preload track metadatameaning information about the track (e.g., duration), not its audio frames. May be called either with the passage name or with a link markup. Returns the number of moments within the past in-play history (past only). If you've removed/hidden the UI bar, a construct like the following will allow you to toggle the views on and off: Note: Does not modify the original. Configuration API. An array of discrete arguments parsed from the argument string. This does not alter the volume level. If the condition evaluates to false and an <> or <> exists, then other contents can be executed. SugarCube includes polyfills for virtually all JavaScript (ECMAScript) 5 & 6 native object methodsvia the es5-shim and es6-shim polyfill libraries (shims only, no shams)so they may be safely used even if your project will be played in ancient browsers that do not natively support them. Deserializes the given save string, created via Save.serialize(), and loads the save. If you need to know if the player has ever been to a particular passage, then you must use the State.hasPlayed() method or the hasVisited() story function. Note: Happens at the end of passage navigation. 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". The directory and .py file names within the archive available for download are already properly matchedas sugarcube-2 and sugarcube-2.pyand to avoid issues it recommended that you simply do not rename them. To enable test mode from the Stories screen, click on the story's gear menu and select the Test Play menu item. Creates a single-use link that deactivates itself and appends its contents to its link text when clicked. This is only really useful within pure JavaScript code, as within TwineScript you may simply access temporary variables natively. Returns whether the given slot is filled. Essentially I want the I'm having some issues getting a major part of my game working, and I'm not sure if this is possible at all. A set of opening and closing tagsi.e., defines the verbatim HTML markup. Starts playback of the track and fades it from the specified volume level to 0 (silent) over the specified number of seconds. Triggered at the end of passage navigation. Block widgets may access the contents they enclose via the _contents special variable. Additional timed executions may be chained via <>. :). For game-oriented projects, as opposed to more story-oriented interactive fiction, a setting of 1 is strongly recommended. See Story API for more information. See the <> section of the Twine1 reference documentation for more information. Tip: The line continuation markup performs a similar function, though in a slightly different way. 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. Note: Sets the default KeyboardEvent.key value that causes the currently running <> macro instance to finish typing its content immediately. Resets the setting with the given name to its default value. Thanks a lot for providing this macro! Warning: Identical to calling .map().flat(). Sometimes there are breaking changes, however, and these must be addressed immediately. This macro has been deprecated and should no longer be used. Happens after the displayi.e., outputof the incoming passage. Renders the given markup and appends it to the dialog's content area. Gets or sets the mute-on-hidden state for the master volume (default: false). See Also: Warning: May be called with either the link text and passage name as separate arguments, a link markup, or an image markup. Tip: The History API object has been renamed to State and some of its methods have also changed. Tip: Does not modify the original. Maybe its there by implication, but it certainly wasnt obvious to me. Each link removes itself and all other <> links to the same passage after being activated. 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. Outputs a string representation of the result of the given expression. Creates a checkbox, used to modify the value of the variable with the given name. Harlowe's implementation of data types differs significantly from SugarCube's. Subtracts the value on the right-hand side of the operator from the current value on the left-hand side and assigns the result to the left-hand side. Does not modify the original. 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. Deprecated: All of the specified callbacks are invoked as the wrapper is invokedmeaning, with their this set to the this of the wrapper and with whatever parameters were passed to the wrapper. Allows the destination of passage navigation to be overridden. The glass appears (with the arrow cursor) and moves far from the image limits. This does not reclaim the space reserved for the UI bar. Whenever your story is first started or, for any reason, restartede.g., the browser window/tab was refreshed/reloadedit undergoes its startup sequence. Like in Harlowe, some SugarCube macros accept expressions and others accept discreet arguments. Stops playback of all currently registered tracks. It should be plain text, containing no code, markup, or macros of any kind. If you're using SugarCube at all, you're using version 1, which does not include that function. Warning: Non-generic object types (a.k.a. The second, and also mandatory, character of the variable name may be one of the following: the letters A though Z (in upper or lower case), the dollar sign, and the underscore (i.e., A-Za-z$_)after their initial use as the sigil, the dollar sign and underscore become regular variable characters. State.current is not a synonym for State.active. 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. Etc. If you simply want to apply actions to multiple tracks simultaneously, then you want a group instead. Opens the dialog. Used for pre-story-start initialization tasks, like variable initialization (happens at the beginning of story initialization). Harlowe refers to these as "revision macros". See Fullscreen API for more information. Save objects have some of the following properties: The state object has the following properties: Each moment object has the following properties: Deletes all slot saves and the autosave, if it's enabled. Calling the State.prng.init() methodformerly History.initPRNG()outside of story initialization will now throw an error. Solution 1: Using before defining - Uncaught ReferenceError: $ is not defined Case: Invoking the function or using a variable before declaring it. If no autosave exists, then the starting passage is rendered. Normally, this is exactly what you want to happen. 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. Unsets story $variables and temporary _variables. Returns whether a Passage object referenced by the given title exists. The StoryInit special passage is normally the best place to set up tracks. 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. See: Note: Mobile browsers can be fickle, so saving to disk may not work as expected in all browsers. 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 a callback function that wraps the specified callback functions to provide access to the variable shadowing system used by the <> macro. For example: See: For example: (not an exhaustive list). Engine API. Note: Those that bundle SugarCube v2: Any series of Twine2 with a version 2.1. In your menu passages, your long return links will simply reference the $return story variable, like so: Warning (Twine2): Selects all internal link elements within the passage element whose passages do not exist within the story. This is a collection of tips, from how-tos to best practices. In use, replacement patterns are replaced recursively, so replacement strings may contain patterns whose replacements contain other patterns. answered Sep 6, 2017 by greyelf (159k Warning: Shorthand for jQuery's .on() method applied to the audio element. Note: 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. Removes and returns the last member from the array, or undefined if the array is empty. Returns a reference to the current AudioRunner instance for chaining. Twine1/Twee: Registers the passage as JavaScript code, which is executed during startup. Determines whether the audio subsystem automatically pauses tracks that have been faded to 0 volume (silent). Returns a new array consisting of the source array with all sub-array elements concatenated into it recursively up to the given depth. When choosing a format, SugarCube is hard to go wrong with. Probably most useful when paired with <>. 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. Note: Audio runners are useful for performing actions on multiple tracks at once. There are several configuration settings for saves that it would be wise for you to familiarize yourself with. Yield the single line in the final output: An exclamation point (!) Have a question about this project? Returns whether the engine is processing a turni.e., passage navigation has been triggered. Note: Note: Macros fall into two broad categories based on the kind of arguments they accept: those that want an expressione.g., <> and <>and those that want discrete arguments separated by whitespacee.g., <> and <
