Well LOL, 'bout chewing ram... 2.9999952 fixes a problem introduced
probably a couple of months ago: the Server software in xelagots, av99bots,
srvcxlgbots and the stand-alone versions, even if it was not being used, was
very slowly but surely chewing up memory (memory leak). This bug has now
been fixed in all bots and servers.

I agree 100% with Anduin Lothar: bots should not be allowed to take
decisions like this. If a human, after cosidering a case, decides a bot must
eject a certain person, that's ok with me, but the human decides, not the
bot :)

I don't know if that is possible, but my xelagot bot has an option to
produce a sound (wav) on your computer when someone arrives. There must not
be any wavs playing in the world though, they take over. Of course, only
you, your wife/husband and granny hear it, no one in the world does :)

For Xelagot users:
The latest version fixes the Announce Text bug introduced a week ago.

For programmers:
It also has a brand new way of dealing with disconnections. Up to this
version, the bot relied on the SDK to handle disconnections. Very often, the
blocking action of the Winsock code used by the SDK would freeze the bot and
user interface during a disconnection. Now, I use the following method:

1. If the session number of the bot (aw_session), which I monitor at every
'heartbeat' and in every event handler and callback, changes to one of
these:
RC_CONNECTION_LOST
RC_UNABLE_TO_CONNECT
RC_NO_CONNECTION
I issue and aw_destroy to log off the bot, and try periodically to create a
new instance and log the bot back in until this succeeds.

2. But, if the bot gets a world error event indicating a disconnection,
without its session number changing to an error code as above, I issue a
aw_exit and then periodically an aw_enter. So the bot still stays in the
Universe in this case. The codes I use here are the ones given in the event
world_disconnect for rc:
RC_CONNECTION_LOST // 471
RC_UNABLE_TO_CONNECT // 429
RC_NO_CONNECTION // 439
RC_NO_SUCH_WORLD // 27
RC_WORLD_NOT_RUNNING // 489 (admin closed world)
These same error codes are tested in the aw_enter callback: any other error
code will stop the bot from carrying on trying to enter the world, these
five will trigger a timer (60 seconds later) to issue a new aw_enter.

Note that blocking still occurs: aw_login and aw_enter block. The callbacks
for both of these, as far as I could establish, are synchronous instead of
asynchronous: the function returns only after the callback has triggered.
But this blocking is less, usually, than the one happening during
disconnections if one leaves the SDK go it's way.

A few weeks ago, Roland advised me to use a similar method to the one I have
now adopted: at any sign that something has gone wrong, destroy the instance
and try to log back in. I am using a slightly milder approach :)

Can you give an example of what IsNumeric does? In Delphi, when I parse a
string and expect an integer, for example, I could use this:

function IsInteger(const s: string): Boolean;
var
n: Integer;
begin
try
n := StrToInt(s);
Result := True;
except
Result := False;
end;
end;

a similar method can be used for others, like for Double etc...
Hope this helps. XelaG

I've used these for a long time, maybe they are useful to you. Note that I
break the search in ExtractVal if a letter E is found, because E is a sign
for exponential, and is considered by Delphi as part of a number. I think
you could use ExtractNumber.

function ExtractVal(var ss: string; var vv: Double): Boolean;
{ss and v only change if first part of ss contain a Real}
var s: string; i, k: Integer; v: Double;
begin
Result := False;
if Length(ss) = 0 then exit;
k := 1;
while (Pos(ss[k], '.+-') > 0) do begin
inc(k);
if k > Length(ss) then break;
end;
s := ss;
for i := k to Length(s) do begin
try
if CompareText(s[i], 'e') = 0 then break;
v := StrToFloat(Copy(s, 1 , i));
vv := v;
if i < Length(s) then ss := Copy(s, i + 1, Length(s)) else ss :=
'';
Result := True;
except
break;
end;
end;
end;

function ExtractNumber(const a: string;
var a1: string; var nr: Double; var a2:string): Boolean;
// splits string into 3 parts: a1, numeric nr, a2 if successful
var i: Integer; s: string; d: Double;
begin
Result := False;
a1 := a;
nr := 0;
a2 := '';
if Length(a) = 0 then exit;
for i := 1 to Length(a) do begin
s := copy(a, i, Length(a));
if ExtractVal(s, d) then begin
Result := True;
if i > 1 then a1 := Copy(a, 1, i-1) else a1 := '';
nr := d;
a2 := s;
break;
end;
end;
end;

Another interesting one is this one.

'a' is a string you want to split

'sep' is a substring where string 'a' has to be split, it can be a space, or
a comma, or any combination of characters.

'tail' is what is left over after splitting string 'a'

action = 0 if you don't want to 'trim' both string 'a' and 'tail'

if sep is not found, then it returns 'a', and 'tail' is empty.

function ZSplit(a, sep: string; var tail: string; action: Integer): string;
var u, l, lsep: Integer; r: string;
begin
if action > 0 then a := Trim(a);
r := a;
tail := '';
u := Pos(sep, a);
if u > 0 then begin
l := Length(a);
lsep := Length(sep);
r := Copy(a, 1, u-1);
if action > 0 then r := Trim(r);
if u+lsep <= l then tail := Copy(a, u+lsep, l-u-lsep+1);
if action > 0 then tail := Trim(tail);
end;
Result := r;
end;

Mar 31, 2001, 8:16am

Same one, with uppercase L .... :)

function ZSplit(a, sep: string; var tail: string; action: Integer): string;
var u, L, Lsep: Integer; r: string;
begin
if action > 0 then a := Trim(a);
r := a;
tail := '';
u := Pos(sep, a);
if u > 0 then begin
L := Length(a);
Lsep := Length(sep);
r := Copy(a, 1, u-1);
if action > 0 then r := Trim(r);
if u+Lsep <= L then tail := Copy(a, u+Lsep, L-u-Lsep+1);
if action > 0 then tail := Trim(tail);
end;
Result := r;
end;

If you don't call AW_WAIT, you don't collect the events anyway, and after 60
seconds or so, your bot gets disconnected. So as MrGrimm says: *install*
the event handler using AwEventSet AW_EVENT_AVATAR_ADD (or else
sdk_EventAvatarAdd() will never get triggered because it is not recognised
as an event handler by the aw.dll), and then *call* sdk.AwWait 0 once a
second (or more often if you like, I call it 16 times a second now in the
new xelagot, the AW browser calls it at every frame). To call AwWait, you
can use a windows Timer if you like, set to an interval of 1000 milliseconds
or even less (mine is at 64 milliseconds)

Tony, the question mark corresponds to a world status of
AW_WORLDSTATUS_UNKNOWN, this happens I think when the connection between the
world server and the universe server is not fully operational. They may
have been having connection problems yesterday.

Are you tired of copy-pasting your speeches one line at a time into the AW
browser? Use a Xelagot to deliver them!

X1 version 2.9999953 has this ability through the user interface.
Previously, you needed to write a script to deliver a speech with a xelagot,
now you can just copy-paste your speech (or part of it) into the bot's chat
or whisper box, and hit ENTER. The speech will be delivered at a reasonable
pace, one line at a time. If you need to stop all ongoing speeches, go to
the menu "Bot | Kill Text" and click on it.

Nightwalker:

If you have build 19 of Canopus' Delphi SDK, you need to change one thing
and add 2 in the akAWAPI.pas

change
AW_BUILD = 19;
to
AW_BUILD = 20;

Then, in the type AW_ATTRIBUTE, you need to look for these attributes:
....
AW_WORLDLIST_NAME,
AW_WORLDLIST_STATUS,
AW_WORLDLIST_USERS,
AW_EJECT_SESSION,
AW_EJECT_DURATION,
....

and add, after AW_WORLDLIST_USERS, AW_WORLDLIST_MORE:
....
AW_WORLDLIST_NAME,
AW_WORLDLIST_STATUS,
AW_WORLDLIST_USERS,
AW_WORLDLIST_MORE,
AW_EJECT_SESSION,
AW_EJECT_DURATION,
....

As last addition, look for
type AW_WORLD_STATES =(
AW_WORLDSTATUS_UNKNOWN,
AW_WORLDSTATUS_PUBLIC,
AW_WORLDSTATUS_PRIVATE
);

Add at the end AW_WORLDSTATUS_STOPPED (dont forget tp add a comma after
AW_WORLDSTATUS_PRIVATE):
type AW_WORLD_STATES =(
AW_WORLDSTATUS_UNKNOWN,
AW_WORLDSTATUS_PUBLIC,
AW_WORLDSTATUS_PRIVATE,
AW_WORLDSTATUS_STOPPED
);

That's all as far as changes in the wrapper. If you use the world list, you
have to change the way you handle the callback AW_CALLBACK_WORLD_LIST.
Supposing your callback is called cbkWorldList(rc: Integer);

procedure cbkWorldList(rc: Integer);
var
BtInstance, BtSession: Integer;
NeedMore: Boolean;
begin
BtInstance := aw_instance;
BtSession := aw_session;
NeedMore := aw_bool(AW_WORLDLIST_MORE) <> 0;
// here test NeedMore:
if NeedMore then begin
// more worlds to come
// call again aw_world_list() for your BotInstance
end else begin
// all worlds have been received
// process your world list
end;
end;

[View Quote] Lots of benefits: when doing intensive property querying, for example, it
runs *much* faster, because it is only when you call aw_wait that the bot
collects the info sent by the servers (events, callbacks) and consequently
can act upon that information. So, if you collect it once a second, you can
only respond once a second, but if you collect 16 times a second, you can
spead up the response.

Obviously, if the bot is doing nothing and there are little or no events
coming, this benefit won't show. I could test the difference when I made
the new 3.1 world backup routines using the cell iterator. The backup was
done16x faster when I changed the bot's heartbeat (where it calls aw_wait)
from 1 beat a second to 16 beats a second !

Apr 4, 2001, 8:51pm

Well, if you can have 16 frames per second with the aw browser, your cpu can
handle it :) The aw browsers call aw_wait at each frame.

A word of caution: if you go too fast, remember that the aw coordinates are
expressed in integers (cm)... if you move your bot's coordinates at such
small intervals, you might reach the point when your step per interval will
get so small that it will be under the centimetre mark and your bot will not
move, I had problems with that for implementing walk, join, etc.

What you see in the browser is not what you get :)

Try this: give your bot 2 commands, one after the other: warp to x y z, seed
object where you are.

You will see the bot moving towards its destination, and if that is like say
20m away, while the bot is still half way on the road the object will appear
at destination. This is a normal consequence of the browser's need to show
fluid movement...

The position of an avatar in the browser is calculated by the browser, not
by the world server. The world server, in my experience, sends the correct
coordinate, but the browser sometimes fails. A notorious example in the past
(which is now apparently solved) was the zero altitude bug. If you
teleported from any altitude to zero altitude, without changing other
coordinates, the browser would not show the change... this was easy to
verify, all browsers watching the avatar would suffer from this illusion,
you just needed to move your bot (or your own avatar if you were the one who
had moved to 0a) one centimeter forward, and it would also descend/ ascend
to 0a in all renderers.

I mentioned a similar bug when 2.x appeared: in some occasions, my bot would
move towards me, but the browser would fail to register... but if I changed
from 1st to 3rd person view, suddenly my bot would adopt the correct
position.

Possibly related to these bugs is the still occuring 'sunken' avatars,
especially noticeable with old avatars which have the 0 0 0 coord at eye
level.

And the 3.0 browser introduced an even more noticeable bug, especially
noticeable when bots are involved: if an avatar moves in a straight line
exactly from north to south, the avatar keeps twitching back to face north.
The first time I noticed this was when making a script for a ship bot... the
enormous Galleon was acting spastic when going from north to south, and only
when it was moving exactly to a southern coordinate without changing the
western one. I don't know if this bug is still there.

There seems to be a permanent problem with the last step of the avatar in
the browser... the routine for that should really be checked.

Check the help files about this.

1. X1 does not scan the area so as not to interrupt building and other
activities, it remembers (on file) the object numbers. Because of that, the
object numbers can get out of sync. This was supposed to be a feautere, but
turns often into a bug. If its never built the objects, it makes them, and
remembers the number the sdk passes it *before* the object is sent to the
server and between sessions, keeps the numbers on file. These number are
used to delete the objects. X1 does not use object change, it used object
delete (which can fail) and object add.

2. There have been problems with negative coordinates at cell boundary (east
and southern regions), that the browser did not refresh properly. I thought
Roland had fixed this.

3. In some future release, I will attempt to better this code... when I have
time :)
