This is very cool.
I've often thought it'd be cool to have a node on a deathmatch net that
wasn't running doom but ran a program that controlled one of the
players. You would have to simulate the internals and networking of
the Doom engine (completely non-trivial) but you could skip all of the
3d graphics. The result would be a player that was totally
programmable.
You could make him into a terminator-like thing that dodged perfectly,
never missed, always ran full speed, knew the location of all objects,
and more personally, knew where you were, what weapons you had, what
your stats were...
Anyway, it'd be easy for him to gather weapons and health while hunting
down the weakest player.
Of course, you could make it more random and limit anything you wanted
in order to to make it more fair for humans to compete against.
Probably waaay too much work, but keep us posted on your examination of
the packet contents.
FWIW, I'm not suggesting this for cheating on DMs though it could be
used for that. I'd use it as a new monster to gang up on in DMs.

Have you noticed that the running frag count displayed on each players status
bar, as well as DWANGO's running frag count are unaffected by a player
leaving the game, but that the tally screen shown when an exit is activated
doesn't reflect any frags made by or on the player(s) who have left the game
before the exit was activated?

When a player is killed, he looks at the player/monster who killed
him, right? So there must be a value for this somewhere in the
package... or at least the value that tells you who (if anyone)
gets the frag credit (or debit in the case of self-destruction).

The problem with a monster that is "underwater" is that it can be shot
even if it is underwater, and the blood would appear at whatever height
you set for it. So if you set the hieght to 1, it would be hard to hit,
i could only be hit by bullets and explosions (projectiles would pass
over it)- all this would look nice while underwater, but when it sprang
up, the blood splats would still appear on the ground, and projectiles
would seems to pass through it. If you set the hieght to high, you could
shot it with anything while "underwater" and the blood splats would appear
in the air above it. Unfortunately, you can't change the hieght bit of
any thing from it's set value using code pointers.
Speaking of code pointers, check out LummoxJR's DeHackEd Grab Bag Page,
it had a code pointer listing that's very helpful.

The C header file describing the DOOM packet structure (as of 1.2)
has been released by Id Software in 1993. It has been posted
several times, and is part e.g. of the file at UDS Errata/Addendum
page at
http://www.nero.uni-bonn.de/~bernd/uds.html
I'd guess the only change is "choosing the new shotgun".

The UDS Errata/Addendum page at
http://www.nero.uni-bonn.de/~bernd/uds.html
will not be updated anymore. In fact, there haven't
been many updates so far, so I'd guess there's no
real need.
In any case, the page will still be around for
months to come. If you haven't ever looked at it,
you might want to do so - five weeks of hard work
might always save you from five minutes reading.

D**mIII total conversion: please remember that this is, as
far as all non-technical aspects are concerned, off topic.
The TNT project used another mailing list for this purpose.
I'd recommend contact them and ask how they organized
things.
Private messages: D**mIII or not, are off topic.
Unsubscriptions: we still unsubscribe w/o warning.
Steve and me have been busy the last two weeks, thus traffic
got a bit out of control. Trust me this will change next
week.
However, for the same reason (lack of time) I won't be able
to take care of doom-editing any longer (read: from
January, 10th on). This means we (read: Steve) could use a
volunteer who is willing to spend some (read: an unreasonable :)
amount of time on taking care of bounces, delivery failures,
off topics. If you want to know details, please contact
us at owner-doom-editing@nvg.unit.no.
Btw., this has happened before. In fact, Steve and me answered
a posting like this quite some time ago...
See you on the other side.

One consideration on the attack frames of the "fake marines" patch... You
could change the attack pattern for some of the monsters to be that of the
"lost souls" so the marine would run at the player quickly, then the next
frame of attack would be either shotgun, rocket, pistol or chaingun. This
would cause an effect of running straight for the player and firing at the
same time and could be confusing as to what is what until you really get a
good look at how they are behaving... Plus increase the hit points to 100
instead of 20 (or whatever the troopers are...) so they can't be as easily
killed off.

I believe that this is due to the fact that there are only one set of sprites
assigned to the death frames (the ones where the player appears to be looking at
you).
I have heard that there is a 3d death patch that contains frames for the other
seven views on ftp.cdrom.com, but have not had a chance to try it yet.
