Anyone care to comment?
Anarchy Online
Armageddon: <URL:telnet://ginka.armageddon.org:4050>
To my knowledge the ONLY truly successful full-bore RP environment
based on a Diku-style server with full combat and the like. Often
cited as such at any rate. [Raph K]
Asheron's Call: <URL:telnet://??:??>
If I recall correctly this is one of the first first-person graphical
commercial muds. (after Ultima Online and its predecessors)

referred to as Cold/Genesis or ColdX/Genesis.
ColdMUD: <ftp://ftp.kanga.nu/pub/MUD/Servers/ColdMUD/>
ColdMUD is for all intents and purposes dead. Greg Hudson officially
stopped development of it back in 1994, and I just 'branched' the
ColdX/Genesis from it, rather than making an issue with people and
continuing to call my development of it 'ColdMUD'. [Brandon Gillespie]

Tron: <URL:telnet://polaris.king.ac.uk:3000>
An out and out pk mud, more of an arcade game using ASCII maps than
a mud in the conventional sense. Not one for the faint hearted.

Worlds of Carnage: <URL:telnet//carnage.labs.emich.edu:4000>
The first Diku mud with an internal scripting language, called
"easyacts." This code formed the basis of the MobProgs put into
Merc 2.2. LegendMUD is a spiritual offshoot of Carnage, and Cythera is
a literal offshoot. (Interestingly, Damion Schubert, a designer on
M59, was also a Carnage immort alum). Imperium Gothique's scripting
was derived from either mobprogs or Carnage, not sure which. Carnage
definitely had a lot of influence on the world of Dikudom. [Raph K]

6. Glossary of Terms
The list has managed to come up with its own jargon. Here are some of
the current buzzwords:
Cooperative role-playing: Refers to a specific kind of RP where each
player's personal 'storyline' is paramount. All players are aware
of, and sensitive to, the needs of each player for their story, and
all actions are completely consensual. This is a type of play often
found on MUSHes.
Event: A system design alternative to polling loops. Objects generate
events, which are processed in their proper order by the event
handler. This is frequently clearer and far more efficient,
especially with large numbers of objects. Examples are a torch
generating an event to burn out in two hours, or a spell generating
an event for an earthquake to occur in four seconds.
The following is a compilable example of generic event-handling code in
C courtesy of Adam Wiggins.
---<begin code>---
#include <stdio.h>
typedef float Tick; /* Time counter type */
/* Defines for event types */
enum { EVENT_ALPHA = 0, EVENT_BETA, EVENT_GAMMA, NUM_EVENTS };
/* The event structure itself */
typedef struct SEvent
{
int Type; /* EVENT_x */
Tick RipenTime; /* time at which event ripens */
void *Data; /* any extra data to be passed to the callback function */
struct SEvent *Next; /* next node in the linked list of events */
} Event;
/* Defininiton for the callback function type */
typedef void (*EventCallback)(void *);
#define EVENT(x) void (x)(void *)
/* Event function prototypes - these should be defined somewhere else, like
so:
EVENT(EventAlpha)
{
code to execute on event completion;
}
*/
EVENT(EventAlpha);
EVENT(EventBeta);
EVENT(EventGamma);
/* Master list of event callbacks, by type */
EventCallback EventCallBacks[NUM_EVENTS] =
{ EventAlpha, EventBeta, EventGamma };
Event *EventList = NULL; /* Master event list */
Tick GameTick = 0; /* Current game time */
/* Call this to add an event "time" ticks into the future */
void AddEvent(int type, Tick time, void *data)
{
Event *newEvent, *e, *prev;
/* Sanity checking */
if (time <= 0)
return;
/* Create the event */
newEvent = (Event *)malloc(sizeof(Event));
newEvent->Type = type;
newEvent->RipenTime = GameTick + time;
newEvent->Data = data;
/* Descend the list until a later event is found */
for (e = EventList; e && e->RipenTime < newEvent->RipenTime; e = e->Next)
prev = e;
/* Insert the new event before that event */
newEvent->Next = e;
if (prev)
prev->Next = newEvent;
else
EventList = newEvent;
}
/* Call the function below during your update loop */
/* The parameter is how many game ticks have passed since the last update */
void EventUpdate(Tick ticks)
{
Event *e, *next;
int update = 0;
GameTick += ticks;
/* Execute each event that is due to ripen */
for (e = EventList; e && e->RipenTime <= GameTick; e = e->Next)
{
(*EventCallBacks[e->Type])(e->Data);
update = 1;
}
/* Second pass, delete all ripened events */
/* This part is done in a seperate pass in case one of the event callbacks
adds a new event, to avoid munging up the event linked list */
if (update)
{
for (e = EventList; e && e->RipenTime <= GameTick; e = next)
{
next = e->Next;
free(e);
}
EventList = e;
}
}
---<end code>---
Faucet->Drain economy: A virtual economic system wherein there is an
ongoing influx of new items into the game (usually via a reset model)
and a hopefully corresponding outflow, usually accomplished through
object attrition involving equipment damage, rent fees, etc. It is worth
noting that traditionally, designers have been unable to easily come up
with a big enough drain to handle all the 'water.' This is as opposed to
a "Closed economy" in which an attempt is made to close the loop,
creating new objects only when old ones are used up. [Raph K]
Fixed random seeding: Using a fixed value (such as a character's
unique ID, or the character's position in XYZ space) to seed the
random number generator, assuring that the same random number will
always be rolled if the circumstances are exactly the same, but
requiring no storage. This allows parts of the world or its
behaviour to be dynamically generated from the seed value as
needed, and yet to have each "new copy" be the same as all the
others because the seed value hasn't changed.
Fluidity of Identity: Referring to the difficulty of positively identifying
a single person who takes many guises in a game world. Any particular
action against one of those guises is fairly ineffective; they choose
another and continue. This makes it very difficult to pin down
trouble makers. ATtempts at identifying people based on their hostname
(site deny/allow), e-mail address (email registration), credit card number
(for commercial ventures), or just asking really, really nicely are all
easily circumvented, especially when it is easy to create new characters
or
accounts (that is, the process is short and automated). This frequently
makes it difficult to implement 'real world' solutions to in-game problems
such as psychotic killing sprees. Once you catch someone and lock them
away
or put them to death in RL, they are gone. When you do this on most muds,
they just log on two seconds later with another character.
Full world reset, aka "groundhog day" muds: Muds wherein resets occur
globally, simultaneously (sf reset and repop). [RaphK]
Functional roleplaying: A kind of gaming, whilst GoP motivated, is heavily
tailored to the in-game reality. There's no thee's or thou's, or even
pretension of IC/OOC separation, but an awful lot of attention is spent
by the player in working his character thru the game realities rules as
it controls and affects his character. Examples would include
negotiation of reputation and influence systems, votes, political systems,
clans and guilds and other similar structures, etc. Appearance is not
the key. Function is. [JCL]
Global namespace: Referring to the fact that most muds rely on characters
(and sometimes other objects) are given a single and unique name.
Typing 'who' on most muds gives you a list of these; if you see
someone named Bob you know that he is the only Bob in the world, and
can't be confused with anyone else. This is as compared to a system
of generated descriptions to which players can attach proper names
as they please, which may or may not overlap or match up with the
names assigned by other players.
GoP: Short for 'game-oriented play' or possible 'goal-oriented play'.
This is usually a competitive style of play usually oriented around
the accumulation of various resources (money, power, combat ability).
Levels: For the purpose of keeping discussions generic, this term may be
used as an abstract measurement of a character's ability, skill or
expertise whether the game system is level-based or skill-based.
Eg: "If a low level character tries XXX a high level character..."
The precise details are not of interest as opposed to the impact and
result of the undefined imbalance.
Lockless server or DB:
Events request objects from the DB.
If the object is not in the cache, the DB loads the object.
The DB replies to the event with a read-only shared reference to the
object.
The event is added to the "interested parties" list for the object.
If the event attempts to modify the object, a new local, event-specific
copy of the object is made, and the changes are made to that. A copy
of the original reference however is still kept.
The event (loosely) attempts to keep track of what members of the
object it referenced.
During the execution of an event. all external IO is buffered and held.
Upon the event terminating it compares its copy of the original object
(the local reference) with the object that's actually in the DB (may
have been changed by events committing during the current event's
execution). Some intelligence is attempted here to only compare those
values etc which were referenced by the event.
Should the original copy and the current-in-DB copy compare OK, then
the event commits, the IO is released, and all its changes in its
written-to copies are committed atomically. This is the
Compare&Commit, or C&C.
If the C&C fails, the event is thrown away, all the copies are released,
the IO is discarded, and the event is rescheduled to try again.
There is also some background intelligence here where the DB watches
the objects that are affected by event's C&C'ing, and will signal the
other events that are members of those object's interested party list
that they may be invalidated by the other event's C&C and so should
kill themselves and reschedule.
ref: DEMOS and the DOME project (JCL)
Markup language: An internal set of codes used by a server to generate
semi-dynamic messages. An example is "%c dives %I %o" which might result
in "Bubba dives behind the wall", "A woman dives into the pool", or
any number of other strings.
mud or MUD: It is not an acronym. It is a collective term for all the
types of games discussed on this list, including both RP and GoP.
[NB: Another description may be found at the list's homepage
<URL:http://www.kanga.nu/lists/listinfo/mud-dev/> ]
Mule: Character created on goal-orientated muds those sole purpose is to
supplement a player's primary character by supplying services such as
equipment repair. Mules usually have skills that cannot be obtained
without creating a new character but are perceived to be undesirable to
play. For example, an alchemist class could be considered unenjoyable
to play but due to their special ability to repair equipment, the regular
players create mule alchemists just to access that ability.
Object: Because most of the servers discussed here are
object-oriented, the word object is being used in its general
programming sense to include characters, locations, inanimate items,
and so forth, rather than referring to only inanimate items as is
typical in some mud servers.
PK, player-killing: The intentional killing of a player character by
another player, with or without the first player's prior knowledge,
agreement, or consent. [JCL]
Psychological disinhibition: The term for when people act less inhibited
than normally because of circumstance. All behaviours online tend to become
less inhibited, and the greater the absence of identity cues for the
people
you are interacting with, the less inhibited the behaviours tend to get.
[RaphK]
Realism: This is not necessarily correspondance to the real world, but
rather refers to internal consistency. In many cases using the
working of real world systems (physics, for example) is a good
example for how to build a consistent system for a game world.
To quote:
"This is, of course, partially my invention, to suit the gaming world
we are working on, and is not intended to mirror Real Life - just to
borrow enough bits and pieces from it, so that it is recognized as
somewhat structured (rather than totally whimsical) to the player."
- Holly Sommer
Repop: See Reset.
Reset: Usually a function called in a mud at irregular intervals, the
purpose of which is to put back the game, or some fragment of the
game or game world into a known state. Typically this might mean
locking an opened door, or resurrecting an NPC that was killed by a
player and putting him back to guard the door, Resets and repops
are common on games that promote repetitive actions for advancement.
Skill net: A single layered skill web. Skills are directly weighted to
each other. See skill web (NY)
Skill tree: A skill system where skills have a single parent and
several children. A skills at the bottom of the tree being very
specialised. Skills higher up the tree will affect the value of
skills further down.
Skill web: a non-hierarchical two layered skill system wherein each
skill is weight-related to an arbitrary number of attributes, and
the improvement of skills therefore automatically improves related
skills. Examples of skills might be rowing and flycasting, examples
of attributes, strength (upper arm) and precision (forearm).
[Note: I triple weight my skill web, so that there are direct
connections to the condition of the character's body and mind, and
so that the resilience of same are improved by conditioning. Nathan Y]
[Note 2: The web is modelled after a simple neural net design I found in
Dr. Dobbs' Journal. Nathan Y]
Verb binding: Attaching verbs to an object, such as 'fly' to a
jetpack. The command essentially does not exist when you don't have
the jetpack.
Virtual sociopath: a player who shows no empathy towards any other players
and therefore is a willing killer of them) but who is perfectly normal
in real life--someone whose disassociation from others only occurs in
an online setting, because of their lack of empathic connections to
other players. See "psychological disinhibition." [RaphK]
World state: a mud which saves world state is one in which there is
persistence not only of characters but also of objects other than
characters. Worlds which do not save world state (such as muds derived
from Dikus) only save character data and the world itself (other than its
static map) is not persistent over reboots. A snippet from my website:
--->
The "middle layer" referred to is the one of the three layers of
significance in a virtual world: that which is the static database, that
which is the play of data on said static database, and that which is the
dataset of players themselves. Depending on the method of state-saving of
the mud, they may save one, two, or all three of these things. As an
example, a classic Diku saves only the third layer: players. Ultima Online
saves both players and the environment. A typical MUSH saves players, the
environment, and also the actual map and setting which holds the
environment, since MUSHes allow dynamic alteration of the static data.
Some
early muds did not save any of the three, and thus were not truly
"persistent."
