I guess we're back into the affect vs Affect vs spoof game again.
I'll see if I can't get somethingoether on the area for spoofs.

Didn't see that one. Orion Henry and I stared a spirited chat on the
area in r.g.m.m back when (which I think ended up with me inviting him
to the old list).

Note: A combat script needs to be able to codify the above set of
planned attacks, defenses etc. It should also be able to handle
something of the form:
"Smash Boffo with buckler while kicking Bernie in the goolies, and
waving my sword in Blubbo's direction. If Blubbo runs, then feint
chopping Boffo's head of, and stab him, in the leg. If Blubbo attacks
high, drop to the ground and smash his kees with the buckler. If
Blubbo uses his mace, feint at his face with the sword, block with the
buckler, and roll away. If Bernie attacks my legs, jump on top of him
and break neck while blocking with buckler. If Blubbo doesn't attack
me, feint high, smash arm with buckler and stab with sword in
It is from here that the below primitives (attack, defend, sequence,
etc) were derived.
>:Hurm. A combat script needs to be able to express the following:

Because the definition of damage is both contextual and subjective.
Consider the staged mana fight I posted earlier:
UggUgg slashes at you with his Sword of Instant Beheading
and minor discomfort!
> cast soakhole on uggugg
You cast the dreaded mana eater soakhole on UggUgg!
UggUgg sneezes and buries your in green snot!
Your armour suddenly dissappears!
Your spell of magical summon protection fails!
Your spell of magical sight fails!
UggUgg's Nose Ring of Killer Snot dissappears!
UggUgg's Belt of Gas Containment dissappears! Phew!
UggUgg's dagger of wart removal dissappears!
> cast create mana
You create 5,000 units of mana!
Your mana stores are now empty.
You are now magically potected from summons.
You can now see all magically hidden objects.
UggUgg thows a blade of painful castration at you!
You leap mightily.
The blade misses! You are still a baritone.
> attack uggugg with spear
You ram UggUgg through with the spear of Icy Death!
UggUgg now has the flu and looks a bit watery about the eyes.
UggUgg picks up a rock.
UggUgg bases you with a rock! Ouch! That hurt!
> throw TC at uggugg
You throw the charmed trash collector at UggUgg.
The TC englobes UggUgg!
UggUgg gives you the Sword of Instant Beheading and minor
UggUgg gives you the Boots of Mighty Chilblains,
UggUgg gives you the Goggles of Big Farts.
UggUgg gives you Super Nose Hair Puller.
The TC has eaten everything UggUgg was carrying! Yech!
UggUgg is naked!
Your spell of magical summon protection fails!
Your spell of magical sight fails!
Your spell of magical tummy tuck fails!
Your spell of power voice fails!
Your spell of land control fails!
Your spell of bowel control fails!
Your spell of toe cheese protection fails!
> stat spells
You have no spells.
> stat mana
There is no mana here.
> strangle uggugg
You wrap your hands about UggUgg's neck and begin to squeeze!
UggUgg prays to the Great God GooGoo!
GooGoo mana blesses the area!
There is a LOT of mana here! You skin prickles!
You have a mana shielding sack
> l in sack
There are 5,000,000 TC spores in the sack.
>empty sack on UggUgg
The spores eat all the mana!
There are 5,000,000 TC's here! Wow.
All the mana is gone!
In one case UggUgg gave his magical objects to you to exhaust your
mana and cause your and his magical objects to instantly decay, and
your spells to fail. The problem here is that this action is not
necessarily harmful. It depends on whether you consider the
destrution of the magic items to be damaging or not (their absence
certainly simplifies the combat), whether your mana reserves can
withstand the strain, or even whether those magic items are actually
helpful to you to accomplish something you want (last component for a
super spell?) There's a lot of context here, and a lot of subjective

I have two contentions here:
1) Combat is not a state. There is (or should be) no equivalent to
a flag being set to indicate a combat condition.
2) Result, not intent or activity characteristics, defines combat
I'm (recently) firmly convinced now that the classical model of having
a combat state is so inherently flawed that it is indefensible.
The problem (for me) which raises #2 above is that I've just turned
combat on its ear. Fairly obviously (or at least safely assumably)
someone running up and trying to run you thru with a spear is, err,
both unfriendly and attempting to kill you. However someone giving
you some magic objects, or TC's, or partially/fully exhausting the
mana (for something harmful/helpful/innocuous/unrelated?) in a room
you happen to also be in, or taking something from you, or damn near
anything can now, subjectively, be VERY easily classified as a violent
life-threatening attack, massively helpful, or ignorable.
Its this second generality that raises the interest points for me.
The MUD world, and the comparitive survival and success of other
players in the MUD world has suddenly become something that can be
most easily manipulated and controlled/affected indirectly thru
changes to the _environment_, and not thru attempted effects upon them
You want Bubba dead? Go stand by him and drop a bag of TC spores on
the floor. The TC's hatch, eat all the mana, all Bubba's magical
items and spells decay and fail. The TC's now concentrate on eating
each other, resulting in a few very large TC's, who then attempt to
eat Bubba. You walk out unscathed.
Even more indirect methods are event more effective, decently
guaranteed, and difficult to track.

>Why must the script be able to recognize these as a seperate class of

>ie. failure of the target to display damage after you threw
>everything you had at it?
Nope, the attempted diversion or prevention of damage from an enemy
attack. Bubba chops at you with a sword -- what do you do to prevent
your arm from being severed?
>:-- Feints, where a feint can be an illusory attack or defense.

Because a feint can be used as a diversion to mislead an adversary
into reacting/defending against the feint while your main attack goes
>:-- Sequences, where a sequence is any ordered set of attacks,
>:defenses, and feints (including a sequence of one member).

Sorta. See above.

>:response to a stated sequence or sequence characteristic from a
>:defined or undefined opponent.
>OK, this I can see. But why does it require recognizing the actions
>as "defensive", "feint"?
Because I see those as the atomic sections of sequences. Think of it
ala the forms in Karate, Tai Chi etc. They are a sequence, a known
pre-planned pattern of blocks, attacks, and feints (well sorta).
>:-- Scripts, where a script is a statement of the various sequences and
>:reactions to attempt during a combat round.
>:The design is for every combatant to submit a script (as above) to the
>:controlling Combat Object for the fight for each round (I use round
>:based combats). At the end of the round, the combat object resolves
>:the scripts against each other (eg feedback loops between reactions),
>:and sets the sequences attempted by each combatant. These resolutions
>:are then sent back to the combatants, they do them, the relevant
>:damages are levied (this is all automatic), and the next round starts.

I'm trying hard to get away from having a twitch game; where the human
player's reaction speed, ability to enter commands, and ability to
react quickly and correctly to current state data is key. I want a
game, and I specifically want combat where preparation, planning, and
finesse are are the key elements of combat, and all the twitch stuff
is almost compleatly devalued.
I want combat to have to be a thing of deliberation; not engaged in
lightly, and not participated in without considerable ongoing thought.
This isn't DOOM. This is CRobots with a human face.
>:The problem here is to define a simple user-friendly scripting

A side comment on my intentions for combat:
Newbies whould have a definite if small chance of being able to
kill high level players.
Probability of outcome for any combat should be unstable, if
weighted toward the more skilled.
Result of combat should NEVER be solidly predictable, (Variation
A newbie character played by an expert human player should have
the advantage over a high level character played by a newbie
All blows/spells/etc have a chance of failing, whereupon they all
also have a chance of reflecting back on their source (swing
sword at Bubba and chop off own leg, shell explodes in barrel,
ice spell freezes you instead)
Combat doesn't last long. Less than 5 - 10 minutes IRL.
And of course: Death is permanent.

True, they reek of their pulse/heartbeat based systems. The problem
is that I explicitly DON'T want to pace normal action in the game. If
the guy wants to walk across the entire land, and can enter (and have
the server process) the commands quickly enough, then by Gum, he'll
walk 10,000 miles in 3 seconds flat. The comparitive problem with
this is that I want combat to be forced to be a less hurried affair,
and thus requiring pacing.
Or so I semi-thought.
>:Consider the hyopothetical battle I posted earlier:
>:Your giving the charmed TC to UggUgg __acted__ as an attack in the
>:context of a fight because the TC attempted to eat UggUgg's inventory.
>:However, normally giving someone a TC, even a charmed TC would not be
>:an attack. Similarly, UggUgg giving you his magical inventory in an
>:effort to exhaust your mana stores and cause all your magical objects
>:to destruct in the context of this fight was an attack. However
>:giving someone a macgical item or items during a fight is often NOT an
>:attack. This same sort of dichotomy holds true for the TC spores.
>Not really. Whatever your intent, the results are the same, yes/no?
Nope. The actual result could be beneficial, innocuous, or harmful
depending on your subjective evaluation.
>The only complaint I can see is that this means the script has to
>have a friend/foe value for the other guy...
Not in any system I have anything to do with.
>:These are not fighting actions any more -- but in the context of a
>:magical battle where indirect control and manipulation of the the mana
>:supply is the major weapon, they suddenly turn into fighting actions.
>:Think you have a rule?
>Yeah. I think its not that bad, actually. At this point in time, both

>screaming, is going to be interpreted as hostile. Even sneezing.
True. Consider the activity starts however with UggUgg giving you the
magic items. Or starting with your dropping the TC spores...
Determining when a combat state is initiated (something I think
shouldn't be done anyways) is *really* messy.
>:I'm beginning to think that fights should be handled like any other
>:player interaction. Let each player enter individual commands for
>:each blow which are then handled as if they were exactly the same as
>:every other command. Allow automation of this process via scripts
>:etc, but forget the whole deal of combat objects, rounds, etc. Let
>:the guy pick his nose one command, shoot his neighbor the next, and
>:water his garden the third.
>Yup. Now your talking sense. *grin*
