Why did you write all this after i needed it ? i had to get out my math book
to find
how to translate polar and carthesian coordinates :)

and moving in cirlces seems to be everyones dream (besides deer, that is)
since i did it similar :)

i don't know if it makes much sense to calculate an altitude angle... in

As you pointed out, a moving object can't be seen. and a avatar is made for
"moving" :)

but for collision detection, its implemented in the browser for avatars, not
into the server or SDK for bots. or am i wrong at this point ? my bot daniel
passes through everything without problems :)

if you don't use the gesture for ball treatment, but the move instead, you
could have distance and strengt..

if you run against your ball, it has much strength, it you just walk against
it, it will run off more slow...

which would mean you have to monitor the last few movements and time
indices, as the browser does for interpolating the avatar paths, which,
unfortunately means any network traffic jam would influence your ball
response.

just my 2 cents...

Ah, i see.. you are right, that perspective put the bot into the server
position :)

its just that a bot as a ball is just another participant in the
communication between different clients to the aw-server, and therefore i
found it confusing.

either compile in release mode (you should do that anyway for a "release"

or switch to static linkage of MFC if your programm is really that simple..

I found my bots to dissappear if i don't call aw_wait anymore....

It happens in my C++ programm when i am debugging it and keeping it on hold
on a breakpoint.

so make sure you have some kind of mainloop that calls aw_init().... i do
this using a WM_TIMER and calling aw_wait(10); in there, about once a
second.

i have no clue there since I am not into VB. but char * is a common
expressions for API functions as well i think.
For example, lstrcpy is a WIN32 function (exported from kernel32.dll) and it
returns a string pointer like that. So see if you can find a declaration for
that one and use it to create your proper aw_string prototype.

Well, to solve that problem of focus loosing you can either ..


do as i do an talk to your bot inside of AW mostly...

and second, you might want to use the FindWindow() API call and ShowWindow()
to bring the AW
browser to the front from your bot programm, but i don't really think thats
a bright idea.

but its better than having the browser render while beeing inactive... it
would use way to much CPU time.

Is it true, that the main world AW is now closed for bots as well ?

its bad that aw_enter does not return giving an error code, and
its even MORE bad that beta seems the only bot open place now....

bots are not that interesting if you run them in an empty world only...


Walter aka Faber

Nov 18, 1998, 6:31pm

You are correct, an invisible bot does not have a current position,
therefore its located nowhere. for that matter, nobody can see or hear it,
and it does not see or hear anybody.

which means its only useful to query property, to add / change / delete
objects or to change world parameters, because those actions are not related
to a current bot position.

and it looks like the only thing you are not allowed to do is confuse and
annoy users with your bot hanging around on GZ. so if it has no current
position or one outside of GZ, you can do everything, even querying property
on GZ.

What do you mean by "what is really returning this error?"

When you encounter an STATUS_ACCESS_VIOLATION while doing string
manipulations I guess its the system preventing your program from running
away. So it would help alot if you'd post what string manipulations you do.

A Stack backtrace like that is meaningless without a debuggee with symboled

the only common number here is c0000005 wich is share violation.... same

It would help if you stated one or two of the errors you got, and the types
of the bots you run. You are correct in your assumption that a corrupted
aw.dll would prevent any bot from running.

a WM_TIMER is not at all the same as a seperate thread, but since the SDK is
not thread safe anyway and since it doesn't make sense to move more than
once a second, a WM_TIMER does the job.

so set up a second timer, and add a routine to it which does the following
(pseudo code following)

OnMoveTimer ()
{
get_old_position();
my_current_x := my_current_x + random_value_between(-100, 100);
my_current_z := my_current_x + random_value_between(-100, 100);
my_current_yaw := my_current_x + random_value_between(-100, 100);
my_current_yaw := my_current_yaw MODULO 3600;
int success = aw_change_state();

if (success)
{
save_current_position();
}
}

well, i think i got 3 languages in the above code, but the point should be
clear :)

hope that help a little,

Nov 16, 1998, 8:28pm

Since a bot programm has a 3 bots limit, i guess you don't need active
objects for it. the programm responds quite well to 3 bots from a single
thread. even lengthy build operations do not stop other bots from
responding, since the sdk functions call your callbacks while waiting for
server results.

just my 2 cents..

The Borland should have tools to create an import library from a dll. try
to locate a tool
called "implib.exe" or try to find it the documentation.

this is how previous MS C++ handled that. you called the aforementioned tool
like that:

"implib aw.dll"

and it should create the dll.

i don't know if borland supplies a tool like that, but it's worth a try.

Edward,

implib programms are compiler specific nowadays. they collect the neccessary
information for dynamic linking, but don't really create a standard libary
with actual code in it anymore, so that the compiler can use the collected
information to create dynamic linking code on the fly as needed.

so that kind of library would have to be coded manually, using c only,
released in source, and compiled by the one going to use it.

On the other hand it's hard to believe that the Cygwin32 DLL support is that
poor. a windows development is NOTHING with at least plain DLL import
library support, so i wonder if CygWin32 does have an implib.exe equivalent
which we do not know and which would have prevented a lot of work and
thought.

Preston 20 was released today..

Build 20

- Preston can now have more than one owner. Seperate the names with "," in
the bot owner field. For example: Faber,Ima Genius
- A bug was fixed which would cause Preston to crash when Preston's internal
userlist had only one entry, and that user would leave and come back. This
bug has been around for quite some time now, and reported by many people.
- A bug was fixed with the follow mode. "me" is now properly recognized as
the follow target again

We have disabled all previous builds except for 19 and 20.

maybe its the right time to look into c++ ?

just if you wonder, its possible to write a GUI bot using c++ in VC5.0, so
6.0 should work too.. this is what [Daniel] is.

Really ? I never needed the session numbers. In every event callback i have
the instance, and then pass all the event information the the c++ bot object
responsible for that bot instance. doing it this way a bot object does only
get the information related to him. If an avatar comes close to more than
one bot at a time, i get the event twice, once for each bot instance, so
that approach works just fine.

i still have no idea for what the session number is needed outside the
aw.dll.

It never rejected a positon change for me, and i errorneously had tests
running with 100 changes a second. i guess it discards them or does not
propagate them to other people, but it does not reject them.

Interesting...

i was building the bot from a AWBrowser-User point of view. You see if more
than one person approaches you in AW and talks to you, you get all
statements mixed in the chat window. this is, of course, just what happens
to my bot if more than one guy is talking to it.

For now that does not matter, because the conversations to my bot consist of
simple give-a-command and get-a-direct-response. No conversation context.

But if i wanted to establish chat context, there's still no need for a
session id. for every conversation you have a bot's instance and an
avavatar's name. So as soon as my c++ bot objects are able to keep
conversation context, they would of course remember to whom, and there you
are. so my AWBrowser-User point of view would work here. The user does not
have "session ids" and therefore the bot does not need them either.
