The attack doesn't even have to be one such that it deliberately harms you.
Intention isn't a factor, since the decision to retaliate will always rest
with the victim (who can code his scripts appropriately:  that is, if he's
the jumpy sort, almost everything will cause him to retaliate, whereas
someone more calm would perhaps let an "attacker" get away with more).  For
example, if I'm sitting in a tavern, someone across the room chucks an
ale at me and it hits me in the head, I think whether or not I'd consider
it an attack would depend on my personal mood at the moment.  In any case,
it's my choice to get up and kill him, or just let it pass.  To a point,
though, I suppose that sort of decision cannot truly be automated, since
the number of factors seems (to me) to be substantial.  This implies that
the victim has to actively begin his retaliation combat script, rather than
having it kick in automatically (note that the jumpy sort has it easy,
since everything can kick in automatically).

I understand Nathan's PoV on this one, I think because I'm leaning the same
way:  I don't plan to make any distinction between offensive and defensive
actions, short of saying that offensive means damage can be done and
defensive means damage can be prevented.  Will the user coding his combat
script care if his defensive action is an illusory attack or just a
straight parry?  If there is a different advantage to using one over the
other, then yes, but does the combat engine require a distinction between
the type of defense?

Can sequences simply be chained-together commands with the odd conditional?
And then extrapolate to chained-together scripts?

If you build the conditional into the combat scripting, then I'm not sure
you'd need reactions, since anything inside the conditional would be the
reaction to an action that the conditional evaluated to true.

I'm curious, Nathan, how long your "average", session...lasts?
Is it fast-paced (assuming, say, a couple of matched-ability guys knocking
about with swords)?  Does each combatant have control over each atomic
attack (i.e. Ugg swings sword at Bubba.  Bubba sees this and then has a
slice of time to choose his reaction to Ugg's swing.  Etc.), or is it more
automated?  I'm not happy with the traditional combat model:  I want there
to be more thought and involvement in it, rather than just swinging your
sword, automatically blocking, and casting spells left and right.  I just
haven't hit upon a comfortable solution yet.

Well, is it plausible to simply use the commands that a character already
has available, with the addition of a conditional that would allow checking
to determine what a char's reaction will be?  This will definitely become
more involved (and possibly quite messy) with multi-character combat...

I have an affinity for this scheme, but I agonize over it being too slow
to give the "feel" of combat.  However, perhaps continuous speed from the
start of the battle to the end isn't a factor:	Have any of you seen the
duel at the end of "Rob Roy"?  It wasn't a particularly speedy thing (and
that makes sense, I suppose...a claymore is probably a bitch to whirl
around), so perhaps some speed can be sacrificed in the interests of
combat "feel".  <shrug>

If things are going so fast and furiously, are people then relying on their
scripts to go through the action-reaction motions for them (since I think
it will be difficult to keep track of a really fast battle if you're
manually typing each action and reaction command)?
