Area 51

Jump to navigation Jump to search

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_documentation/Template to add new entries in the sections below.

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

mapSymbolFontInfo()
See also: setupMapSymbolFont(...)
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).

Note Note: pending, not yet available.

setupMapSymbolFont

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

Note Note: pending, not yet available.

Miscellaneous Functions

Miscellaneous functions.

getCharacterName

getCharacterName()
Returns the name entered into the "Character name" field on the Connection Preferences form. Can be used to find out the name that might need to be handled specially in scripts or anything that needs to be personalized to the player. If there is nothing set in that entry will return an empty string.

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.

See also: sendCharacterName(), sendCharacterPassword(), sendCustomLoginText(), getCustomLoginTextId().

Example
lua send("cast 'glamor' " .. getCharacterName())

You get a warm feeling passing from your core to the tips of your hands, feet and other body parts.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A light brown faun gambles around you and then nuzzles your hand.
A tawny long-haired cat saunters over and start to rub itself against your ankles.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A light brown faun gambles around you and then nuzzles your hand.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A mangy dog trots up to you and proceeds to mark the bottom of your leggings.

Scripting Object Functions

A collection of arrows that manipulate Mudlets scripting objects - triggers, aliases, and so forth.

Networking Functions

A collection of functions for managing networking.

String Functions

These functions are used to manipulate strings.

Table Functions

These functions are used to manipulate tables. Through them you can add to tables, remove values, check if a value is present in the table, check the size of a table, and more.

Text to Speech Functions

These functions are used to create sound from written words. Check out our Text-To-Speech Manual for more detail on how this all works together.

UI Functions

These functions are used to construct custom user GUIs. They deal mainly with miniconsole/label/gauge creation and manipulation as well as displaying or formatting information on the screen.
