:Creates a miniconsole window for the video player to render in, the with the given dimensions. One can only create one video player at a time (currently), and it is not currently possible to have a label on or under the video player - otherwise, clicks won't register.
 +
 
 +
{{note}} A video player may also be created through use of the [[Manual:Scripting#MUD_Client_Media_Protocol|Mud Client Media Protocol]], the [[Manual:Miscellaneous_Functions#playVideoFile|playVideoFile()]] API command, or adding a Geyser.VideoPlayer object to ones user interface such as the example below.
 +
 
 +
{{Note}} The Main Toolbar will show a '''Video''' button to hide/show the video player, which is located in a userwindow generated through createVideoPlayer, embedded in a user interface, or a dock-able widget (that can be floated free to anywhere on the Desktop, it can be resized and does not have to even reside on the same monitor should there be multiple screens in your system). Further clicks on the '''Video''' button will toggle between showing and hiding the map whether it was created using the ''createVideo'' function or as a dock-able widget.

;createVideoPlayer([name of userwindow], x, y, width, height)
 
  
:Creates a miniconsole window for the video player to render in, the with the given dimensions. One can only create one video player at a time (currently), and it is not currently possible to have a label on or under the video player - otherwise, clicks won't register.
+

;getCustomLoginTextId()
  
{{note}} A video player may also be created through use of the [[Manual:Scripting#MUD_Client_Media_Protocol|Mud Client Media Protocol]], the [[Manual:Miscellaneous_Functions#playVideoFile|playVideoFile()]] API command, or adding a Geyser.VideoPlayer object to ones user interface such as the example below.
+
Returns the Id number of the custom login text setting from the profile's preferences. Returns ''0'' if the option is disabled or a number greater than that for the item in the table; note it is possible if using an old saved profile in the future that the number might be higher than expected. As a design policy decision it is not permitted for a script to change the setting, this function is intended to allow a script or package to check that the setting is what it expects.
  
{{Note}} The Main Toolbar will show a '''Video''' button to hide/show the video player, which is located in a userwindow generated through createVideoPlayer, embedded in a user interface, or a dock-able widget (that can be floated free to anywhere on the Desktop, it can be resized and does not have to even reside on the same monitor should there be multiple screens in your system). Further clicks on the '''Video''' button will toggle between showing and hiding the map whether it was created using the ''createVideo'' function or as a dock-able widget.

Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined ''doLogin()'' function, a replacement for which is shown below.

:Sends given binary data with some predefined special tokens converted to byte values, to the internal telnet engine, as if it had been received from the game. This is primarily to enable testing when new Telnet sub-options/protocols are being developed. The data has to be injected into the system nearer to the point where the Game Server's data starts out than ''feedTriggers()'' and unlike the latter the data is not subject to any encoding so as to match the current profile's setting (which normally happens with ''feedTriggers()''). Furthermore - to prevent this function from putting the telnet engine into a state which could damage the processing of real game data it will refuse to work unless the Profile is completely disconnected from the game server.

* Boolean ''true'' if the ''data'' string was sent to the internal telnet engine.

Additionally, if the data is an empty string ''""'' a second return value will be provided as an integer number representing a version for the table of tokens - which will be incremented each time a change is made to that table so that which tokens are valid can be determined.

==getCustomLoginTextId, PR #3952 open==
 
;getCustomLoginTextId()
 
 
 
Returns the Id number of the custom login text setting from the profile's preferences. Returns ''0'' if the option is disabled or a number greater than that for the item in the table; note it is possible if using an old saved profile in the future that the number might be higher than expected. As a design policy decision it is not permitted for a script to change the setting, this function is intended to allow a script or package to check that the setting is what it expects.
 
 
 
Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined ''doLogin()'' function, a replacement for which is shown below.

:Sends given binary data with some predefined special tokens converted to byte values, to the internal telnet engine, as if it had been received from the game. This is primarily to enable testing when new Telnet sub-options/protocols are being developed. The data has to be injected into the system nearer to the point where the Game Server's data starts out than ''feedTriggers()'' and unlike the latter the data is not subject to any encoding so as to match the current profile's setting (which normally happens with ''feedTriggers()''). Furthermore - to prevent this function from putting the telnet engine into a state which could damage the processing of real game data it will refuse to work unless the Profile is completely disconnected from the game server.

==echoPopup, revised in PR #6946==
 
;echoPopup([windowName,] text, {commands}, {hints}[, useCurrentFormatElseDefault])
 
: Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like echo. The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line; if there is one extra hint then the first one will be used as a (maybe containing Qt rich-text markup) tool-tip for the text otherwise the remaining hints will be concatenated, one-per-line, as a tool-tip when the text is hovered over by the pointer.
 
 
 
; Parameters
 
* ''windowName:''
 
: (optional) name of the window as a string to echo to. Use either ''main'' or omit for the main window, or the miniconsole's or user-window's name otherwise.
 
* ''text:''
 
: the text string to display.
 
* ''{commands}:''
 
: a table of lua code to do, in text strings or as functions (since Mudlet 4.11), i.e. <syntaxhighlight lang="lua" inline="">{[[send("hello")]], function() echo("hi!") end}</syntaxhighlight>.
 
* ''{hints}:''
 
: a table of strings which will be shown on the right-click menu and as a tool-tip for the ''text''. If the number is the same as that of the ''commands'' table then they all will be used for the right-click menu and listed (one per line) as a plain text tooltip; alternatively if there is one extra in number than the ''commands'' table the first will be used purely for the tool tip and the remainder will be used for the right-click menu. This additional entry may be formatted as Qt style "rich-text" (in the same manner as labels elsewhere in the GUI).
 
::* If a particular position in the ''commands'' table is an empty string ''""'' but there is something in the ''hints'' table then it will be listed in the right-click menu but as it does not do anything it will be shown ''greyed-out'' i.e. disabled and will not be clickable.
 
::* If a particular position in '''both''' the ''commands'' and the ''hints'' table are empty strings ''""'' then this item will show as a ''separator'' (usually as a horizontal-line) in the right-click menu and it will not be clickable/do anything.
 
* ''useCurrentFormatElseDefault:''
 
: (optional) a boolean value for using either the current formatting options (color, underline, italic and other effects) if ''true'' or the link default (blue underline) if ''false'', if omitted the default format is used.
 
 
 
;Example

==== name====
 
 
 
For example, to simply play the sound of a cow mooing already stored in the "media" folder:
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "cow.wav"
 
}
 
</syntaxhighlight>
 
 
 
Or some lightning stored in a "weather" sub-folder under the "media" folder.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "weather/lightning.wav"
 
}
 
</syntaxhighlight>
 
 
 
The "name" parameter may be used for stopping media with the Client.Media.Stop GMCP event.
 
 
 
====url====
 
 
 
If you maintain your sound files on the Internet and don't set a default URL with Client.Media.Default, or preload them with Client.Media.Load, include the "url" parameter:
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "cow.wav",
 
  "url": "https://www.example.com/sounds/"
 
}
 
</syntaxhighlight>
 
 
 
====type: sound====
 
 
 
Media files default to a "type" of "sound" when the "type" parameter is not specified, such as in the example above. It is good practice to specify the "type" parameter to best keep media organized within your implementation:
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "cow.wav",
 
  "type": "sound"
 
}
 
</syntaxhighlight>
 
 
 
The "type" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
 
 
 
====tag====
 
 
 
To play the sound of a sword swooshing and categorized as "combat":
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "sword1.wav",
 
  "type": "sound",
 
  "tag": "combat"
 
}
 
</syntaxhighlight>
 
 
 
The "tag" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
 
 
 
====type: music====
 
 
 
Add background music to your environment through use of the "music" value set upon the "type" parameter:
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "river.wav",
 
  "type": "music",
 
  "tag": "environment"
 
}
 
</syntaxhighlight>
 
 
 
The "type" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
 
 
 
====volume: 1 to 100====
 
 
 
As the character draws nearer to or farther from the environmental feature, consider adjusting the "volume" parameter.  Example values, followed by syntax examples:
 
 
 
*Maximum: 100 (recommended to use rarely)
 
*High: 75
 
*Default: 50
 
* Low: 25
 
* Minimum: 1 (recommended to use rarely)
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "river.wav",
 
  "type": "music",
 
  "tag": "environment",
 
  "volume": 75
 
}
 
</syntaxhighlight>
 
 
 
Although using the integer type is recommended, Mudlet parses "volume" values of type string ("75") into integers (75) as needed.
 
 
 
====fadein====
 
 
 
Increase volume from the start of the media [start position, volume one] to the number in milliseconds specified with the "fadein" parameter [position start + milliseconds, volume specified with the "volume" parameter].  Example values, followed by syntax examples:
 
 
 
*1000 milliseconds (1 second)
 
*60000 milliseconds (1 minute)
 
*0 milliseconds (no fade in)
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "monty_python.mp3",
 
  "type": "music",
 
  "volume": 100,
 
  "fadein": 1000
 
}
 
</syntaxhighlight>
 
        +---------------------------+-----------------------+
 
        | Fade in 1000 milliseconds |        Normal        |
 
        +---------------------------+-----------------------+
 
Volume 1|........::::::::::iiiiiiiii%%%%%%%%%%%%%%%%%%%%%%%%|Volume 100
 
        +---------------------------+-----------------------+
 
Although using the integer type is recommended, Mudlet parses "fadein" values of type string ("1000") into integers (1000) as needed.
 
 
 
==== fadeout====
 
 
 
Decrease volume from a position in milliseconds subtracted from the duration of the media [position duration - milliseconds, volume specified with the "volume" parameter] to the end of the media [position duration, volume one].  Example values, followed by syntax examples:
 
 
 
*1000 milliseconds (1 second)
 
*60000 milliseconds (1 minute)
 
*0 milliseconds (no fade out)
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "the_matrix.mp3",
 
  "type": "music",
 
  "volume": 50,
 
  "fadeout": 333
 
}
 
</syntaxhighlight>

          +-----------------------+---------------------------+
 
Although using the integer type is recommended, Mudlet parses "fadeout" values of type string ("333") into integers (333) as needed.
 
 
 
==== start ====
 
 
 
Start playing a media track at the number of milliseconds specified.  Example values, followed by syntax examples:
 
 
 
*1000 milliseconds (1 second)
 
*60000 milliseconds (1 minute)
 
*0 milliseconds (start from beginning)
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "mudlet_beatboxing.mp3",
 
  "type": "music",
 
  "volume": 75,
 
  "start": 1000
 
}
 
</syntaxhighlight>
 
 
 
Although using the integer type is recommended, Mudlet parses "start" values of type string ("100") into integers (100) as needed.
 
 
 
==== finish ====
 
 
 
Finish playing a media track at the number of milliseconds specified.  Example values, followed by syntax examples:
 
 
 
*1000 milliseconds (1 second)
 
*60000 milliseconds (1 minute)
 
*0 milliseconds (start from beginning)
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "mudlet_beatboxing.mp3",
 
  "type": "music",
 
  "volume": 75,
 
  "finish": 35000
 
}
 
</syntaxhighlight>
 
 
 
Although using the integer type is recommended, Mudlet parses "finish" values of type string ("100") into integers (100) as needed.
 
 
 
==== loops: -1, 1 or more ====
 
 
 
The "loops" parameter controls how many times the sound repeats and defaults to 1 if not specified. A value of -1 will loop the file indefinitely.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "clock/hour_bell.wav",
 
  "type": "sound",
 
  "loops": 3
 
}
 
 
 
Client.Media.Play {
 
  "name": "underdark.mp3",
 
  "type": "music",
 
  "tag": "environment",
 
  "loops": -1
 
}
 
</syntaxhighlight>
 
 
 
Although using the integer type is recommended, Mudlet parses "loops" values of type string ("-1") into integers (-1) as needed.
 
 
 
==== priority: 1 to 100 ====
 
 
 
The "priority" parameter sets precedence for Client.Media.Play GMCP events that include a "priority" setting. The values for the "priority" parameter range between 1 and 100. Given that two Client.Media.Play GMCP events have the same priority, the media already playing will continue playing. In Mudlet, media without priority set is not included comparisons based on priority.
 
 
 
A common place to find priority implemented is with combat. In the following example, imagine a combat scenario where some sounds of sword thrusts were interrupted by a successful blocking maneuver.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "sword1.wav",
 
  "type": "sound",
 
  "tag": "combat",
 
  "loops": 3,
 
  "priority": 60
 
}
 
 
 
Client.Media.Play {
 
  "name": "block1.wav",
 
  "type": "sound",
 
  "tag": "combat",
 
  "priority": 70
 
}
 
</syntaxhighlight>
 
 
 
Although using the integer type is recommended, Mudlet parses "priority" values of type string ("25") into integers (25) as needed.
 
 
 
The "priority" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
 
 
 
====continue: true or false (for music)====
 
 
 
Typically sent with the "type" of "music" is the parameter "continue", which presents the following values:
 
 
 
*true: continues music that is already playing if it is requested again through a new Client.Media.Play GMCP event
 
*false: restarts music that is already playing if it is requested again through a new Client.Media.Play GMCP event
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "city.mp3",
 
  "type": "music",
 
  "tag": "environment",
 
  "continue": true
 
}
 
</syntaxhighlight>
 
 
 
If the "continue" parameter is not specified, behavior will default to ''true'' for music.
 
 
 
Although using the boolean type is recommended, Mudlet parses "continue" values of type string ("true" and "false") into boolean (''true'' and ''false'') as needed, as not all game drivers support a boolean type.
 
 
 
==== key====
 
 
 
The "key" parameter enables media categorization, similar to the "tag" parameter, however it adds a feature of uniqueness that halts media currently playing with the same key, replacing it with the media that arrived from a new Client.Media.Play GMCP event. This update will only occur if the "name" or "url" associated with the currently playing media does not match the new media, while the key is identical.
 
 
 
In the example below, consider that a player moves from a sewer area to a village.  The "key" parameter is used to stop the previously playing ''sewer.mp3'' and start playing ''village.mp3'' within the second Client.Media.Play GMCP event.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "sewer.mp3",
 
  "type": "music",
 
  "tag": "environment",
 
  "loops": -1,
 
  "continue": true,
 
  "key": "area-music"
 
}
 
 
 
Client.Media.Play {
 
  "name": "village.mp3",
 
  "type": "music",
 
  "tag": "environment",
 
  "loops": -1,
 
  "continue": true,
 
  "key": "area-music"
 
}
 
</syntaxhighlight>
 
 
 
The "key" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
 
 
 
{{note}} Where music is bound to change, continue or stop as a player enters a new room, consider allowing for a slight pause of 1 heart beat or tick to send the Client.Media.Play or Client.Media.Stop GMCP events. This practice reduces the number of Client.Media.Play GMCP events sent when the player travels through several rooms quickly.
 
 
 
==== randomization====
 
 
 
Wildcards ''*'' (asterisk) and ''?'' (question mark) may be used within the name to randomize media file(s) selection.
 
 
 
Given that media files underdark.wav, underdark.mp3 and underdark_dark_elven_moshpit.mp3 were all present in the media/environment directory under the current game profile, the following Client.Media.Play GMCP event would randomly choose one of those files to play using the ''*'' wildcard.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "underdark*",
 
  "type": "music",
 
  "tag": "environment",
 
  "loops": -1,
 
  "continue": false
 
}
 
</syntaxhighlight>
 
 
 
If media files sword1.wav, sword2.wav and sword3.wav were all present in the media/combat directory under the current game profile, the following Client.Media.Play GMCP event would randomly choose one of those files to play per each loop using the ''?'' wildcard.
 
 
 
<syntaxhighlight lang="json">
 
Client.Media.Play {
 
  "name": "combat/sword?.wav",
 
  "type": "sound",
 
  "tag": "combat",
 
  "loops": 3
 
}
 
</syntaxhighlight>

=Supported Protocols=
 
 
 
Mudlet supports CHARSET, NEW-ENVIRON, MNES, MTTS, GMCP, MSSP, MSP, ATCP, Aardwolfs 102, MSDP, and the MXP Protocol.
 
 
 
CHARSET, NEW-ENVIRON, MTTS, MXP, MSSP, MSP, GMCP and 102 are enabled by default, MSDP and MNES can be enabled in settings.
 
 
 
==NEW-ENVIRON, PR #7058==
 
To enhance the player experience through sharing more client-supported details, the Telnet New-Environ Option may be used to transfer client environment variables from Mudlet to game servers. Sharing supporting information on information such as encoding, terminal emulation, and accessibility options aims to improve initial player setup and increase the retention rate for new gaming community members.
 
 
 
===NEW-ENVIRON in Mudlet===
 
Mudlet supports two methods of information exchange via NEW-ENVIRON, the first via [https://datatracker.ietf.org/doc/html/rfc1572 RFC 1572]: '''Telnet New-Environ Option''' (on by default), and the second is [https://tintin.mudhalla.net/protocols/mnes/ MNES]: '''Mud New-Environ Standard''' (off by default), which shares a standardized set of client information across multiple clients.
 
 
 
====Client Environment Variable Updates====
 
Mudlet provides a user-friendly interface for managing environmental variables through its Settings menu. For certain environmental variables, manual selections made in the Settings menus can dynamically notify servers that have expressed interest in the client's environmental variables through the negotiation of the NEW-ENVIRON option. For instance, when a Mudlet user updates the data encoding for a server profile by navigating to Settings, General, and choosing a specific data encoding from the drop-down menu, this information becomes available for transmission via both the RFC (default) and MNES (requires user enabling) options.
 
 
 
==== Available Client Environment Variables [https://datatracker.ietf.org/doc/html/rfc1572 RFC 1572] ====
 
Two types of variables are used per RFC 152, well-known variables defines with VAR (0) and for less common variables, USERVAR (3). Some information requires a user to OPT-IN to share it with the game. Some client variables updates may be reported ad-hoc with an INFO (2) message. If there is no value for a defined variable, a VAL (1) will be sent without a value following it.

====Negotiating NEW-ENVIRON====
+
=Mud Client Media Protocol=
Negotiating the NEW-ENVIRON Telnet option empowers game servers to request one, multiple, or all client environment variables configured within Mudlet. The process unfolds with the game server sending a Telopt DO NEW-ENVIRON (39), prompting Mudlet to respond with a WILL NEW-ENVIRON (39). Subsequently, the game server can send SB NEW-ENVIRON (39) SEND to receive all available environment variables. Mudlet responds with SB NEW-ENVIRON (39) IS (0) < VAR (0) | USERVAR (3) > "<variable>" [VAL (1)] ["<value>"] [ .. [ VAR (0) | USERVAR (3) ] "<variable>" VAL (1) "<value>"] containing the list of environmental variables.
+
:All GMCP functions to send sound and music events. For an overview on how all of these functions tie in together, see our [[Special:MyLanguage/Manual:Scripting#MUD_Client_Media_Protocol|MUD Client Media Protocol scripting overview]].
  
Once an environmental variable is transmitted to a server within the ongoing connection, Mudlet replies with SB NEW-ENVIRON (39) INFO (2) < VAR (0) | USERVAR (3) > "<variable>" [VAL (1)] ["<value>"] messages for select variables. Importantly, no reply from the server is required in this context. If there is a need to specify a particular list of requested environmental variables to Mudlet, the format SB NEW-ENVIRON (39) SEND < VAR (0) | USERVAR (3) > "<variable>" [ .. < VAR (0) | USERVAR (3) > "<variable>" ] can be employed.

==MTTS, PR #7036==
 
MUD servers frequently seek information about the capabilities of a MUD Client. Despite the availability of various methods, achieving consistency and reliability in this endeavor has proven challenging. The Mud Terminal Type Standard ([https://tintin.mudhalla.net/protocols/mtts/ MTTS]) aims to alleviate these issues by introducing a transparent and straightforward standard for MUD Clients to communicate their terminal capabilities. This standard builds upon and formalizes [https://datatracker.ietf.org/doc/html/rfc1091 RFC 1091], which outlines the Telnet Terminal-Type Option.
 
 
 
===MTTS in Mudlet===
 
By incorporating the Mud Terminal-Type Standard (MTTS), Mudlet will communicate with interested servers that it possesses the following capabilities:
 
 
 
* '''Support for ANSI Color Codes:''' The client supports all common ANSI color codes.
 
* '''UTF-8 Character Encoding:''' The client utilizes UTF-8 character encoding.
 
* '''Support for 256 Color Codes:''' Mudlet is equipped to handle all 256 color codes.
 
* '''OSC Color Palette:''' Mudlet acknowledges support for the OSC color palette.
 
* '''Screen Reader Support:''' Mudlet offers support for screen readers, with opt-in functionality (not advertised by default).
 
* '''Truecolor Codes:''' Mudlet supports truecolor codes using semicolon notation.
 
* '''Mud New Environment Standard (MNES) Support:''' The client adheres to the Mud New Environment Standard for information exchange.
 
* '''TLS Encryption:''' The client supports Transport Layer Security for data encryption.
 
 
 
==== Screen Reader Opt-In ====
 
Users can find on the Accessibility tab under the Settings menu a checkbox identified as "Advertise screen reader use via protocols supporting this notice" which when checked will notify interested game servers. This information may be used to optimize the gaming experience.
 
 
 
[[File:Screenshot_2024-01-01_at_2.35.07_PM.png|alt=Image displaying the Advertise screen reader checkbox|619x619px]]
 
 
 
==== Available MTTS Information ====
 
Through a Telnet TERMINAL-TYPE Option negotiation, Mudlet transfers a bitvector to game servers, (i.e., <code>2349</code>) for processing.  A bitvector, also known as a bitmap, is a data structure that represents a fixed-size sequence of binary digits or bits. In a bitvector, each bit corresponds to a specific position or index in the sequence, and its value can be either 0 or 1. The MTTS bitvector represents is a set of flags and boolean values, where each bit can represent the state of a particular boolean condition or flag. For example, if the third bit is set to <code>1</code>, it indicates that the client is using UTF-8 character encoding. A <code>0</code> indicator would indicate that UTF-8 was not supported.

Latest revision as of 07:25, 25 December 2024

This page is for the development of documentation for Lua API functions that are currently being worked on. Ideally the entries here can be created in the same format as will be eventually used in Lua Functions and its sub-sites.

Please use the Area_51/Template to add new entries in the sections below.

Links to other functions or parts in other sections (i.e. the main Wiki area) need to include the section details before the '#' character in the link identifier on the left side of the '|' divider between the identifier and the display text. e.g.

[[Manual:Mapper_Functions#getCustomLines|getCustomLines()]]

rather than:

[[#getCustomLines|getCustomLines()]]

which would refer to a link within the current (in this case Area 51) section. Note that this ought to be removed once the article is moved to the main wiki area!

The following headings reflect those present in the main Wiki area of the Lua API functions. It is suggested that new entries are added so as to maintain a sorted alphabetical order under the appropriate heading.


Basic Essential Functions

These functions are generic functions used in normal scripting. These deal with mainly everyday things, like sending stuff and echoing to the screen.

Database Functions

A collection of functions for helping deal with the database.

Date/Time Functions

A collection of functions for handling date & time.

File System Functions

A collection of functions for interacting with the file system.

Mapper Functions

A collection of functions that manipulate the mapper and its related features.

mapSymbolFontInfo, PR #4038 closed

mapSymbolFontInfo()
See also: setupMapSymbolFont()

Note Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/4038

returns
  • either a table of information about the configuration of the font used for symbols in the (2D) map, the elements are:
  • fontName - a string of the family name of the font specified
  • onlyUseThisFont - a boolean indicating whether glyphs from just the fontName font are to be used or if there is not a glyph for the required grapheme (character) then a glyph from the most suitable different font will be substituted instead. Should this be true and the specified font does not have the required glyph then the replacement character (typically something like ) could be used instead. Note that this may not affect the use of Color Emoji glyphs that are automatically used in some OSes but that behavior does vary across the range of operating systems that Mudlet can be run on.
  • scalingFactor - a floating point number between 0.50 and 2.00 which modifies the size of the symbols somewhat though the extremes are likely to be unsatisfactory because some of the particular symbols may be too small (and be less visible at smaller zoom levels) or too large (and be clipped by the edges of the room rectangle or circle).
  • or nil and an error message on failure.
As the symbol font details are stored in the (binary) map file rather than the profile then this function will not work until a map is loaded (or initialized, by activating a map window).

moveMapLabel, PR #6014 open

moveMapLabel(areaID/Name, labeID/Text, coordX/deltaX, coordY/deltaY[, coordZ/deltaZ][, absoluteNotRelativeMove])

Re-positions a map label within an area in the 2D mapper, in a similar manner as the moveRoom() function does for rooms and their custom exit lines. When moving a label to given coordinates this is the position that the top-left corner of the label will be positioned at; since the space allocated to a particular room on the map is ± 0.5 around the integer value of its x and y coordinates this means for a label which has a size of 1.0 x 1,0 (w x h) to position it centrally in the space for a single room at the coordinates (x, y, z) it should be positioned at (x - 0.5, y + 0.5, z).

See also: getMapLabels(), getMapLabel().
Mudlet VersionAvailable in Mudlet ?.??+

Note Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/6014

Parameters
  • areaID/Name:
Area ID as number or AreaName as string containing the map label.
  • labelID/Text:
Label ID as number (which will be 0 or greater) or the LabelText on a text label. All labels will have a unique ID number but there may be more than one text labels with a non-empty text string; only the first matching one will be moved by this function and image labels also have no text and will match the empty string. with mo or AreaName as string containing the map label.
  • coordX/deltaX:
A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the X-axis.
  • coordY/deltaY:
A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the Y-axis.
  • coordZ/deltaZ:
(Optional) A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the Z-axis, if omitted the label is not moved in the z-axis at all.
  • absoluteNotRelativeMove:
(Optional) a boolean value (defaults to false if omitted) as to whether to move the label to the absolute coordinates (true) or to move it the relative amount from its current location (false).
Returns
true on success or nil and an error message on failure, if successful it will also refresh the map display to show the result.
Example
-- move the first label in the area with the ID number of 2, three spaces to the east and four spaces to the north
moveMapLabel(0, 2, 3.0, 4.0)

-- move the first label in the area with the ID number of 2, one space to the west, note the final boolean argument is unneeded
moveMapLabel(0, 2, -1.0, 0.0, false)

-- move the second label in the area with the ID number of 2, three and a half spaces to the west, and two south **of the center of the current level it is on in the map**:
moveRoom(1, 2, -3.5, -2.0, true)

-- move the second label in the area with the ID number of 2, up three levels
moveRoom(1, 2, 0.0, 0.0, 3.0)

-- move the second label in the "Test 1" area one space to the west, note the last two arguments are unneeded
moveRoom("Test 1", 1, -1.0, 0.0, 0.0, false)

-- move the (top-left corner of the first) label with the text "Home" in the area with ID number 5 to the **center of the whole map**, note the last two arguments are required in this case:
moveRoom(5, "Home", 0.0, 0.0, 0.0, true)

-- all of the above will return the 'true'  boolean value assuming there are the indicated labels and areas

moveRoom, PR #6010 open

moveRoom(roomID, coordX/deltaX, coordY/deltaY[, coordZ/deltaZ][, absoluteNotRelativeMove])

Re-positions a room within an area, in the same manner as the "move to" context menu item for one or more rooms in the 2D mapper. Like that method this will also shift the entirety of any custom exit lines defined for the room concerned. This contrasts with the behavior of the setRoomCoordinates() which only moves the starting point of such custom exit lines so that they still emerge from the room to which they belong but otherwise remain pointing to the original place.

See also: setRoomCoordinates()
Mudlet VersionAvailable in Mudlet ?.??+

Note Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/6010

Parameters
  • roomID:
Room ID number to move.
  • coordX/deltaX:
The absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the X-axis.
  • coordY/deltaY:
The absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the Y-axis.
  • coordZ/deltaZ:
(Optional) the absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the Z-axis, if omitted the room is not moved in the z-axis at all.
  • absoluteNotRelativeMove:
(Optional) a boolean value (defaults to false if omitted) as to whether to move the room to the absolute coordinates (true) or the relative amount from its current location (false).
Returns
true on success or nil and an error message on failure, if successful it will also refresh the map display to show the result.
Example
-- move the first room one space to the east and two spaces to the north
moveRoom(1, 1, 2)

-- move the first room one space to the west, note the final boolean argument is unneeded
moveRoom(1, -1, 0, false)

-- move the first room three spaces to the west, and two south **of the center of the current level it is on in the map**:
moveRoom(1, -3, -2, true)

-- move the second room up three levels
moveRoom(2, 0, 0, 3)

-- move the second room one space to the west, note the last two arguments are unneeded
moveRoom(2, -1, 0, 0, false)

-- move the second room to the **center of the whole map**, note the last two arguments are required in this case:
moveRoom(2, 0, 0, 0, true)

-- all of the above will return the 'true'  boolean value assuming there are rooms with 1 and 2 as ID numbers

setupMapSymbolFont, PR #4038 closed

setupMapSymbolFont(fontName[, onlyUseThisFont[, scalingFactor]])
configures the font used for symbols in the (2D) map.
See also: mapSymbolFontInfo()

Note Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/4038

Parameters
  • fontName one of:
  • - a string that is the family name of the font to use;
  • - the empty string "" to reset to the default {which is "Bitstream Vera Sans Mono"};
  • - a Lua nil as a placeholder to not change this parameter but still allow a following one to be modified.
  • onlyUseThisFont (optional) one of:
  • - a Lua boolean true to require Mudlet to use graphemes (character) only from the selected font. Should a requested grapheme not be included in the selected font then the font replacement character (�) might be used instead; note that under some circumstances it is possible that the OS (or Mudlet) provided color Emoji Font may still be used but that cannot be guaranteed across all OS platforms that Mudlet might be run on;
  • - a Lua boolean false to allow Mudlet to get a different glyph for a particular grapheme from the most suitable other font found in the system should there not be a glyph for it in the requested font. This is the default unless previously changed by this function or by the corresponding checkbox in the Profile Preferences dialogue for the profile concerned;
  • - a Lua nil as a placeholder to not change this parameter but still allow the following one to be modified.
  • scalingFactor (optional): a floating point value in the range 0.5 to 2.0 (default 1.0) that can be used to tweak the rectangular space that each different room symbol is scaled to fit inside; this might be useful should the range of characters used to make the room symbols be consistently under- or over-sized.
Returns
  • true on success
  • nil and an error message on failure. As the symbol font details are stored in the (binary) map file rather than the profile then this function will not work until a map is loaded (or initialised, by activating a map window).

createVideoPlayer, PR #6439

createVideoPlayer([name of userwindow], x, y, width, height)
Creates a miniconsole window for the video player to render in, the with the given dimensions. One can only create one video player at a time (currently), and it is not currently possible to have a label on or under the video player - otherwise, clicks won't register.

Note Note: A video player may also be created through use of the Mud Client Media Protocol, the playVideoFile() API command, or adding a Geyser.VideoPlayer object to ones user interface such as the example below.

Note Note: The Main Toolbar will show a Video button to hide/show the video player, which is located in a userwindow generated through createVideoPlayer, embedded in a user interface, or a dock-able widget (that can be floated free to anywhere on the Desktop, it can be resized and does not have to even reside on the same monitor should there be multiple screens in your system). Further clicks on the Video button will toggle between showing and hiding the map whether it was created using the createVideo function or as a dock-able widget.

loadVideoFile, PR #6439

loadVideoFile(settings table) or loadVideoFile(name, [url])
Loads video files from the Internet or the local file system to the "media" folder of the profile for later use with playVideoFile() and stopVideos(). Although files could be loaded or streamed directly at playing time from playVideoFile(), loadVideoFile() provides the advantage of loading files in advance.

Note Note: Video files consume drive space on your device. Consider using the streaming feature of playVideoFile() for large files.

Required Key Value Purpose
Yes name <file name>
  • Name of the media file.
  • May contain directory information (i.e. weather/maelstrom.mp4).
  • May be part of the profile (i.e. getMudletHomeDir().. "/congratulations.mp4")
  • May be on the local device (i.e. "C:/Users/YourNameHere/Movies/nevergoingtogiveyouup.mp4")
Maybe url <url>
  • Resource location where the media file may be downloaded.
  • Only required if file to load is not part of the profile or on the local file system.

getCustomLoginTextId, PR #3952 open

getCustomLoginTextId()

Returns the Id number of the custom login text setting from the profile's preferences. Returns 0 if the option is disabled or a number greater than that for the item in the table; note it is possible if using an old saved profile in the future that the number might be higher than expected. As a design policy decision it is not permitted for a script to change the setting, this function is intended to allow a script or package to check that the setting is what it expects.

Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined doLogin() function, a replacement for which is shown below.

See also: getCharacterName(), sendCharacterName(), sendCustomLoginText(), sendPassword().

Note Note: Not available yet. See https://github.com/Mudlet/Mudlet/pull/3952

Only one custom login text has been defined initially:

Predefined custom login texts
Id Custom text Introduced in Mudlet version
1 "connect {character name} {password}" TBD

The addition of further texts would be subject to negotiation with the Mudlet Makers.

Example
-- A replacement for the default function placed into LuaGlobal.lua to reproduce the previous behavior of the Mudlet application:
function doLogin()
  if getCustomLoginTextId() ~= 1 then
    -- We need this particular option but it is not permitted for a script to change the setting, it can only check what it is
    echo("\nUnable to login - please select the 'connect {character name} {password}` custom login option in the profile preferences.\n")
  else
    tempTime(2.0, [[sendCustomLoginText()]], 1)
  end
end

sendCharacterName, PR #3952 open

sendCharacterName()

Sends the name entered into the "Character name" field on the Connection Preferences form directly to the game server. Returns true unless there is nothing set in that entry in which case a nil and an error message will be returned instead.

Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined doLogin() function that may be replaced for more sophisticated requirements.

sendCharacterPassword, PR #3952 open

sendCharacterPassword()

Sends the password entered into the "Password" field on the Connection Preferences form directly to the game server. Returns true unless there is nothing set in that entry or it is too long after (or before) a connection was successfully made in which case a nil and an error message will be returned instead.

sendCustomLoginText, PR #3952 open

sendCustomLoginText()

Sends the custom login text (which does NOT depend on the user's choice of GUI language) selected in the preferences for this profile. The {password} (and {character name} if present) fields will be replaced with the values entered into the "Password" and "Character name" fields on the Connection Preferences form and then sent directly to the game server. Returns true unless there is nothing set in either of those entries (though only if required for the character name) or it is too long after (or before) a connection was successfully made or if the custom login feature is disabled, in which case a nil and an error message will be returned instead.

Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined doLogin() function, a replacement for which is shown below.

sendAll PR #7536 (merged)

sendAll([time delay], list of things to send, [echo back or not])
sends multiple things to the game with an optional delay between sends. If you'd like the commands not to be shown, include false at the end.
See also: send()
Example
-- instead of using many send() calls, you can use one sendAll
sendAll("outr paint", "outr canvas", "paint canvas")
-- can also have the commands not be echoed
sendAll("hi", "bye", false)
-- add an optional delay (in seconds, accepts decimals) which slows down the sent commands
-- 2 second delay, then sends "hi", 2 second delay then sends "bye", 2 second delay then sends "wave")
sendAll(2, "hi", "bye", "wave")

sendSocket revised in PR #7066 (Open)

sendSocket(data)
Sends given binary data as-is (or with some predefined special tokens converted to byte values) to the game. You can use this to implement support for a new telnet protocol, simultronics login etc.
success = sendSocket("data")
See also
feedTelnet(), feedTriggers()

Note Note: Modified in Mudlet tbd to accept some tokens like "<NUL>" to include byte values that are not possible to insert with the standard Lua string escape "\###" form where ### is a three digit number between 000 and 255 inclusive or where the value is more easily provided via a mnemonic. For the table of the tokens that are known about, see the one in feedTelnet().

Note Note: The data (as bytes) once the tokens have been converted to their byte values is sent as is to the Game Server; any encoding to, say, a UTF-8 representation or to duplicate 0xff byte values so they are not considered to be Telnet <IAC> (Interpret As Command) bytes must be done to the data prior to calling this function.

Parameters
  • data:
String containing the bytes to send to the Game Server possibly containing some tokens that are to be converted to bytes as well.
Returns
  • (Only since Mudlet tbd) Boolean true if the whole data string (after token replacement) was sent to the Server, false if that failed for any reason (including if the Server has not been connected or is now disconnected). nil and an error message for any other defect.
Example
-- Tell the Server that we are now willing and able to process  to process Ask the Server to a comment explaining what is going on, if there is multiple functionalities (or optional parameters) the examples should start simple and progress in complexity if needed!
-- the examples should be small, but self-contained so new users can copy & paste immediately without going diving in lots other function examples first.
-- comments up top should introduce / explain what it does

local something = function(exampleValue)
if something then
  -- do something with something (assuming there is a meaningful return value)
end

-- maybe another example for the optional second case
local somethingElse = function(exampleValue, anotherValue)

-- lastly, include an example with error handling to give an idea of good practice
local ok, err = function()
if not ok then
  debugc(f"Error: unable to do <particular thing> because {err}\n")
  return
end
Additional development notes

-- This function is still being written up.

feedTelnet added in PR #7066 (Open)

feedTelnet(data)
Sends given binary data with some predefined special tokens converted to byte values, to the internal telnet engine, as if it had been received from the game. This is primarily to enable testing when new Telnet sub-options/protocols are being developed. The data has to be injected into the system nearer to the point where the Game Server's data starts out than feedTriggers() and unlike the latter the data is not subject to any encoding so as to match the current profile's setting (which normally happens with feedTriggers()). Furthermore - to prevent this function from putting the telnet engine into a state which could damage the processing of real game data it will refuse to work unless the Profile is completely disconnected from the game server.
See also
feedTriggers(), sendSocket()
Mudlet VersionAvailable in Mudlettbd+

Note Note: This is not really intended for end-user's but might be useful in some circumstances.

Parameters
  • data
String containing the bytes to send to the internal telnet engine as if it had come from the Game Server, it can containing some tokens listed below that are to be converted to bytes as well.
Returns
  • Boolean true if the data string was sent to the internal telnet engine. nil and an error message otherwise, specifically the case when there is some traces of a connection or a complete connection to the socket that passes the data to and from the game server. Additionally, if the data is an empty string "" a second return value will be provided as an integer number representing a version for the table of tokens - which will be incremented each time a change is made to that table so that which tokens are valid can be determined. Note that unrecognised tokens should be passed through as is and not get replaced.

deleteMultiline PR #6779 merged

ok,err = deleteMultiline([triggerDelta])
Deletes all lines between when the multiline trigger fires and when the first trigger matched. Put another way, it deletes everything since the pattern in slot 1 matched.
See also
deleteLine(), replaceLine()
Mudlet VersionAvailable in Mudlet4.18+

Note Note: This deletes all the lines since the first match of the multiline trigger matched. Do not use this if you do not want to delete ALL of those lines.

Parameters
  • [optional]triggerDelta:
The line delta from the multiline trigger it is being called from. It is best to pass this in to ensure all lines are caught. If not given it will try to guess based on the number of patterns how many lines at most it might have to delete.
Returns
  • true if the function was able to run successfully, nil+error if something went wrong.
Example
-- if this trigger has a line delta of 3, you would call
deleteMultiline(3)

-- same thing, but with error handling
local ok,err = deleteMultiline(3)
if not ok then
  cecho("\n<firebrick>I could not delete the lines because: " .. err)
end

insertPopup, revised in PR #6925

insertPopup([windowName], text, {commands}, {hints}[{, tool-tips}][, useCurrentFormatElseDefault])
Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like echo. The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line; if a tool-tips table is not provided the same hints will also be listed one-per-line as a tool-tip but if a matching number of tool-tips are provided they will be concatenated to provide a tool-tip when the text is hovered over by the pointer - these tool-tips can be rich-text to produce information formatted with additional content in the same manner as labels.
Parameters
  • windowName:
(optional) name of the window as a string to echo to. Use either main or omit for the main window, or the miniconsole's or user-window's name otherwise.
  • text:
the text string to display.
  • {commands}:
a table of lua code to do, in text strings or as functions (since Mudlet 4.11), i.e. {[[send("hello")]], function() echo("hi!") end}.
  • {hints}:
a table of strings which will be shown on the right-click menu (and popup if no {tool-tips} table is provided). If a particular position in both the commands and hints table are both the empty string "" but there is something in the tool-tips table, no entry for that position will be made in the context menu but the tool-tip can still display something which can include images or text.
  • {tool-tips}:
(optional) a table of possibly rich-text strings which will be shown on the popup if provided.
  • useCurrentFormatElseDefault:
(optional) a boolean value for using either the current formatting options (color, underline, italic and other effects) if true or the link default (blue underline) if false, if omitted the default format is used.

Note Note: Mudlet will distinguish between the optional tool-tips and the flag to switch between the standard link and the current text format by examining the type of the argument, as such this pair of arguments can be in either order.

Example
-- Create some text as a clickable with a popup menu, a left click will ''send "sleep"'':
insertPopup("activities to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"})

-- alternatively, put commands as text (in [[ and ]] to use quotation marks inside)
insertPopup("activities to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"})

-- one can also provide helpful information

-- todo: an example with rich-text in the tool-tips(s)
