About

The Lich is third-party software that expands scripting capabilities on Simutronics front end clients (The Wizard and Wrayth for Windows users, and Avalon for Mac OS X users), allowing players to script using the Ruby Programming Language, a high-level programming language with almost limitless capability. The program comes bundled with several scripts, such as scripts that calculate a character's redux, move from any location to another within a database, walk through an area until a creature is found, and spell up a character using all available spells. Also, there is a repository that allows for the quick, easy downloading of user-made scripts through The Lich, itself. Scripts can range from being very simple to quite advanced; for example, there is a script, titled xpSF, that modifies the experience window in Wrayth to display additional information about the character's experience level that updates itself when experience is gained.

What is "Lich"?

Lich is an open source scripting engine for text-based MUDs. It is not a complete front-end in and of itself: it operates much like a proxy server and communicates with the user through their chosen front-end (effectively giving the appearance of expanding the front-end's features with its own). It allows you to write and run scripts for a text-based MUD in the Ruby language.

Lich was originally created by Shaelun, who brought it up from an idea to version 3.57. Starting with version 3.58 through 4.6.56, Lich was maintained by Tillmen. Tillmen's versions focused more heavily on Simutronics games, specifically Gemstone IV. If you are interested in non-Simutronics games, you might be better served with Shaelun's version. Starting with Lich v5, Lich has been forked over by the team at Elanthia-Online to update and continue development in a collaborative format with contributions from both GemstoneIV and DragonRealms contributors. Current installation instructions now use Lich v5.

The Lich is written to be compatible with other third-party software, such as PsiNet and Black Lightning.

What can Lich do for me?

The Lich program, absent of any scripts, doesn't appear to do much of anything (besides allow you to alias commands in the game). What Lich is doing behind the scenes allows you to use pretty powerful scripts, such as:

• go2: This script makes long and short journeys easy. It is powered by a database of 18,677 rooms with 42,695 known movements connecting those rooms (as of 10-2-2010, for Gemstone IV). Some of those movements include tasks such as navigating mazes, dealing with slippery ice, or waiting in line to use a rope bridge. It includes a large list of common locations in each town, and takes you to the closest one. For example typing ";go2 bank" will take you to whatever bank is closest to you.
• narost: This script pops up a window to show you which room you are in on a map. The script originally used only Tsoran's maps, but since those are becoming increasingly outdated, new maps are being created and added to narost. The script continues to show you what room you are in as you move around, changing maps as needed. It allows you to click on a room to make the go2 script take you there, and some other things.
• infomon: This script is responsible for tracking any useful information that the main Lich program doesn't. The most useful thing it tracks is the spells that are on you, and their remaining time. It also keeps track of other peoples spell ranks that use Lich, to give more accurate spell tracking.
• lnet: This script is a simple chat script that allows you to chat with other people using Lich. It is a great source of help for those new to Lich. It also allows scripts to transfer information to other characters (disabled by default) to allow, for example, a spellup script (waggle) to know exactly how many casts of what spells another character needs.
• repository: This script allows you to upload and download scripts from the Lich server. There are many, many more scripts available for tasks big and small.

In addition to the powerful Ruby scripts, Lich can run most WizardFE/Wrayth scripts unaltered. This allows you to use the scripts you already have, but since Lich is running them, you can have any number of them going at once. However, learning a little Ruby goes a long way. Scripts that take a hundred lines in WizardFE/Wrayth can usually be rewritten as a dozen or so lines in Ruby, and work much better.

What operating systems does it work with?

Starting in version 3.58, Lich is written completely in Ruby. This means it should it should run on any platform that can run the Ruby interpreter. Lich is developed on Linux, but the majority of the user base uses Windows (XP, Vista, Win7, Win8).

Installation

Please review the Lich_(software)/Installation page.

Jinx (;repository alternative)

Jinx is a project that is an alternative form of script installation from the default ;repository. It can serve up scripts for download similar to the ;repo however it is not dependent on a single server that may be prone to outages. Any one can set up their own script library, and then users can add it as a source for the ;jinx script to search and download from.

Jinx can be downloaded and installed into your scripts folder from the Elanthia Online github:

https://raw.githubusercontent.com/elanthia-online/scripts/master/scripts/jinx.lic

Right-click the above link and save it into the scripts folder in your lich directory.

Alternatively, the following command can be issued in game via lich to attempt to download the script to the proper directory for you (this command is for when the repository is down and the script cannot be downloaded naturally):

;e require 'open-uri';begin;jinx_remote = open("https://raw.githubusercontent.com/elanthia-online/scripts/master/scripts/jinx.lic"); jinx_local = File.open(File.join(SCRIPT_DIR, 'jinx.lic'), "wb"); jinx_local.write(jinx_remote.read);ensure; jinx_remote.close(); jinx_local.close();end

once installed you can issue:

;jinx help

for basic usage information.

Jinx Lich Repository Mirror

In the event the main ;repository is unavailable, there is currently an actively maintained ;jinx repository that is a direct mirror.

https://github.com/FarFigNewGut/lich_repo_mirror

Scripts can be manually retrieved from this Github repository (they are all located in the lib folder). The repository is also packaged and published for use directly with Jinx:

;jinx repo add ffnglichrepoarchive https://ffnglichrepoarchive.netlify.app

(You can use something shorter instead of "ffnglichrepoarchive" for the repo name if you'd like.)

Once it is setup as a source for ;jinx you can install any scripts from the repo with:

# install script for the first time
;jinx script install <script name> --repo=ffnglichrepoarchive

# update previously installed script
;jinx script update <script name> --repo=ffnglichrepoarchive

For example if you wanted to download or update invdb.lic:

# first install
;jinx script install invdb --repo=ffnglichrepoarchive

# update if you had previously downloaded invdb.lic
;jinx script update invdb --repo=ffnglichrepoarchive

Jinx Lich Repository Offline Update Info

At times the default Lich repository (accessed via ;repo) can go offline, below are some helpful commands to update core Lich related functionality using Jinx.

# ensure running latest jinx.lic for newest compatibility
;jinx script update jinx.lic --repo=elanthia-online

# update spell-list.xml for new spells, cmans, cooldowns, etc
;jinx data update spell-list.xml --repo=elanthia-online

# update gameobj-data.xml for proper classification of NPCs and items
;jinx data update gameobj-data.xml --repo=core

# update mapdb and associated missing map files for graphical use
;jinx data update mapdb.json --repo=core

# update infomon for proper ingame tracking of skills, stats, spells, effects
;jinx script update infomon.lic --repo=elanthia-online

F.A.Q.

Q: Where did my inventory windows go?

A: If you use inventory windows in Wrayth, you’ll find they have disappeared the first time you run Lich on each character. Lich hijacks the setting to provide container contents to scripts. In doing so, it’s unable to tell what the setting was to start with, so it turns it off (from Wrayth’s point of view). Just type “set inv on” to turn it back on.

Q: Why do I keep disconnecting immediately after login?

A: This generally happens on only one character, and affects only Wrayth. It seems to be caused by Wrayth downloading a characters settings from the Simu server. To fix it, change Wrayth to store scripts/highlights/macros/etc locally, or log in once on Wrayth without Lich to allow it to do whatever it’s trying to do.

Q: How come when I cast spells on people it doesn't tell the correct duration for the spell?

A: This is due to not setting permissions correctly with LNet once logged in. In general, most people should be fine with typing: ;LNET ALLOW ALL ALL. This should allow anyone with Lich installed to detect your spell durations. It also allows other things, to see exactly what you can do type ;LNET HELP ingame and read over the output it provides.

Q: How do I enable or disable the various LichID or RealID in room description title?

A: To enable/disable the LichID or RealID you would use one of the following commands in-game:

# LichID
;e Lich.display_lichid = <true|false>

# RealID
;e Lich.display_uid = <true|false>
