GNU compiler

Oct 10, 1998, 3:45pm
Almost all versions of MS Visual C++ are able to produce a new import
library for dlls.
so the Visual 5 version of it does not have to be used.

I woudln't be surprised if GNU C would offer a similar service.

the method i am talking about used to be called implib. It takes a dll-File
and creates an import library from it.


Roland, the sdk i downloaded carried only aw.h, aw.lib and aw.dll. is there
a way to tell what version it is or could
you provide a version.txt with the archive to give that information ?
thanks :)

otherwise, the sdk has been working great for me :)

actually, all DLLs are sort of required to use c function exports in order
to avoid
the name mangling problem.

that means dll exports are usually PASCAL exported functions (the name is
not decorated at all) or sometimes CDECL exported functions (name is
decorated with a leading underscore).

and third option is to export dll functions by ordinal value, which avoids
using function names at all. but i am not sure if a proper import library
can be regenerated in that case, and with aw.dll i can't find any function
names in there.

so you either use the code wrappers or have the import library, but name
mangling settings shouldn't have anything to do with the issue.

Edward,

yes, that is correct for libraries, and for DLLS which require exported c++
mangled names. (rare, but neccessary if you have function overloading or
complete classes)

Well, implib used to be just that, a tool to create dll wrapper libraries..
but that "knowledge" moved more and more into the linker, so that the import
libraries differ from normal libraries in the way that they do not contain
real functions anymore, just additional linking information... the linker
generates the wrappers then.

which did not change the procedure... you have to use implib to create your
import library. it's just that these days the MS IDEs do that autmatically
when creating a dll, so the "implib.exe" is actually gone by now , it is
intregated in the dll building process. which leads to the problem that you
can't use current visual c++ installations anymore for automated wrapper lib
builing of alien dlls.

i must admit that the information i give gets more and more accurate every
time i answer, which unfortunately changes that information more and more :)

implib.exe is not an option for VisualC5.0, and i think not for Visual C 4.0
as well. it used to be for the older versions.

but, since DLLs are so major under windows, i am quite sure gnu C for win32
must have some supporting environment for it.

A little help with a program

The windows world is not POSIX :)

and therefore the select interface differs too. Under windows, it can =
check for SOCKETS only, and windows SOCKETs are not file descriptors.

therefore user-defined events which are not sockets can not be checked =
for this way.

Under windows, events coming in as Windows-Message to a window are much =
more likely...

My apologies Roland, I must have seemed too pushy. I am a 12 year =
veteran in the computer consulting field and understand totally what you =
are going though. We customers can be very annoying at times. Especially =
what we think we know what we are talking about. You are doing an =
excellent job. Don't let us get to you.=20
You are making the right move in solidifying the release you have =
and when I get a darn C compiler I can use I will be right in there with =
you trying to use your API.=20

I would like to think that the comments we are making will =
contribute to the next version of the API and so I would like to =
continue these conversations if you have the time.=20

Let me explain a little more about aw_add_event().=20

Currently your code calls the socket() and connect() functions to =
create connections to the universe and world servers. The socket call =
returns file descriptors that you are adding to an array of file =
descriptors for passing to the select() call. Each time data becomes =
available on one of these file descriptors the select statement drops =
out and your code checks the file descriptor returned to see if the =
event came from the universe connection or the world connection.=20

OK, now we have a requirement to allow user applications to create =
their own files, sockets or timers and they have to have a way to use =
your select statement to do it.=20

You can create the following function=20

aw_add_event (file descriptor, function pointer) {=20

append file descriptor to end of array.=20
store function pointer into another array indexed by the =
file descriptor.=20
}=20

Now change your select function as follows:=20

array =3D { universe, world }=20

while (1) {=20

event =3D select (array)=20
if (event =3D universe) {=20

Read data from universe file descriptor=20
}=20
else if (event =3D=3D world) {=20

Read data from the world file descriptor=20
}=20
else {=20

look up function pointer using file descriptor=20
call users function;=20
}=20
}=20

Now you have a way for the application to add its own file =
descriptors to your sdks select loop. Applications can now implement =
their own timer based bot functions, dynamically receive weather =
information from a weather server and have their bots tell people, read =
random quotes from a file. All without impacting the performance of the =
application. Also, when bots get more sophisticated they will not be =
needlessly chewing up CPU time while polling the event queue, instead, =
your thousands of deer grazing in a distant meadow will only use CPU =
time when they need to be moving.=20

I have writing a number of there types of applications before and =
would be happy to add my experience to future developments. Please don't =
hesitate to ask.=20

Edward Sumerfield,=20
Pesky user.=20

[View Quote] Okay look, I'll be the first to admit that the SDK architecture =
is not perfect for all possible applications. At this point I don't =
want to get into an argument about which features are more important =
than others. The SDK is what I could come up with in the time =
available. Future considerations like Java support, GNU support, =
multi-threading support, etc. are all great ideas and no doubt would =
make the SDK even better. But that's what they are: future =
considerations. Once again, the goal was to get something, anything, =
out there for people to be able to use. As with all aspects of the =
Active Worlds architecture, the SDK is going to be a continually =
evolving work in progress. As time goes by, it will be improved and =
extended along with all other aspects of the platform. The current goal =
is to simply stabilize and test the current SDK more or less as is in =
order to release it for general use. Then we can start thinking about =
the next version. That said, I'm not sure I even understand the =
aw_add_event() suggestion...I don't know how you would add in external =
application-defined events into the SDK, because the SDK would need to =
know how to check for them. How would the programmer tell the SDK to =
check for his/her custom event, keeping in mind that the only event loop =
that the SDK has is a call to select()? I don't have any hard numbers on =
the hardware mix of our customers. Obviously since AW is a =
Windows-based platform just about everyone has a Windows machine. But =
on the server side lately we've been seeing a lot of interest in Linux, =
for example. I'm not even sure yet what platforms most people will be =
running their bots on.I'm assuming that, in the long term, SDK apps are =
going to more or less parallel world servers in terms of platform of =
choice, since most SDK apps will presumably be applications left running =
[View Quote] You mentioned in the thread about the GNU compiler that your =
preference is to port to Sun/Unix machines before GNU because of your =
belief that high performance bots will run on that type of machine. If =
performance is important to you then why is it that you are not =
addressing this inefficient polling architecture?=20

I would even go as far as saying that a threaded API is much =
high priority than having to worry about porting high powered servers.=20

What is the reletive hardware mix of your customers at the =
moment? Windows/Unix/Linix? What percentage of each would you say?=20

Well, Microsoft has given an example on how to architekt that for quite =
some time now..
=20
the listen(), select() and connect() calls have all an asynchronous =
equivalent, which expects a window handle to send a message to
on completion.
=20
the aw.dll would have to use that instead, open a hidden receive window =
for the socket function and have the calling programm have
a proper windows message loop. this is the usualy way and can be =
expected since almost no windows programm can live without that.

and the MFC class library does it exactly that way (although the =
documentation doesn't mention it :) ).
=20
Windows is called Windows because every programm has to use windows, =
regardless of if the users needs them or not :)
=20
that approach would have the advantage that it would work in any =
programm that has a message loop (including other languages), and that =
other events would not be handled or passed-through by aw.dll at all. =
aw.dll could use windows messages as well to deliver events.

So does windows sockets not being file descriptors give us a problem =

If the windows select only listens for sockets how would you =

I must add that if you use windows messages, you follow the microsoft =
way of polluting standards and be stuck on the
windows platform :)

to avoid polling i am quite sure you have to choose different paths for =
unix and windows.

under unix, it would be best to signal events and have handler functions =
act on them.

the best windows way is explained below :)

the bot i wrote uses a aw_wait(10); polling and that works quite well. =
its a c++ written bot, running up to 3 bot at once, and each class does =
it own state keeping. just do not multithread that since =
aw_instance_set() and following aw_say() is not atomic anymore then. :)
but i am getting off topic here...

Bots or Object Agents ?

Feb 7, 1999, 9:33am
After reading this thread it seems like, you want have an SDK application
which is easier to operate than hambot, has no scripts, is more powerful
than hamfon, allows creating bots by people who don't even see hambots
rather simple scripting, and
want to do VISUAL programm while even scripting is above their head ?

excuse me, but visual programming differs NOT AT ALL in the concepts of
textual programming. you still would have to learn a certain programming
type (procedural, functional, list-oriented, object-oriented), and finely
the "plug-together" of the program flow is independant in concept from the
interface.

Textual interfaces have the advantage that you can implement them very
faster and easier while gaining the same as a visual interface. do you have
any idea how much man-power it needs for a decent click-and-point interface
to, say, an OO programming approach ?

You don't want to wait for that or pay the guy doing it. And you propably
wouldn't like to operate it as well. Visual OO modelers for example are NOT
easy-to-use and thats not their purpose. Their just provide a sense of
abstraction which is not even needed for, e.g., hambot scripts.

Any other visual interface, one that is as easy to operate as, say, driving
a car, is unfortunately equally powerful. you can go left, right, straight
and back. Blinking is only for left and right. Suitable for a CarBot, but
NOTHING for a Bot Programming System.

and QA is something different as well... its actually not the different
profession, that really finds bugs, its the fact that you have different
PERSONS, anybody but the author of a program is qualified for QA'ing it.

Eep, it wouldn't hurt if you didn't leave your field of profession regarding
such statements as below.

Walter aka Faber

ps: i am not saying Hambot Scripts are ideal. a bot-making system might take
a different approach but still would use scripting. It might use visual
designing aspects for actuall visual bot needs (etc. walking path's or bot
group formations)

Jan,

its not enough to have the aw.lib in some directory, you also have to change
the project settings to actually link it to your programm.

but VC4.0 might not like the library format. so if the programm settings
really do try to link to it
the linker would complain about using a corrupt library.

Well,

in VC5 for example you go to Project Settings, select the linker tab, and
enter "aw.lib" in the "additional libraries" field. If you forget that, you
get the linker errors below.

Could it be that you compiled other sample bots or programms using different
settings ? or using a makefile ?

Interesting, i saw this on Linux with all the cd writer software. It seems
like one linux theres one party which writes the good software but with lots
of complicated command line arguments, complicated enough so that theres
another party which writes pretty KDE guis which collect the args out of
editfields and do a system() on it.

and the throw a hell of a command output at you if something goes wrong :)

well, i agree, but aw_wait(10) on a timer worked very well for me. I have my
gui, although i command my bot mostly by talking to it in aw :)

and for the call backs, all i do is look up the bot using the instance and
delegate all actions to the bot obect. all you have to do to supply c++ is
you have to route your events.

just keep it single threaded. thats a real disadvantage.

Portability is no issue since the sdk is only available on win32. and
believe me, we have been trying and using cross plattform libraries, and i
would recommend against it. you run into a lot of limitations using those,
and you end up having bad GUIs on all plattforms you support. if you have to
support multiple platforms, design for it and seperate GUI from everything
else, but do so only if somebody pays you for it :)

dialog based bot.... questions & errors

Oct 15, 1998, 7:31pm
Hey PC,

I am answering your question right below :)

Well, the answer to all of this is simple, use CString. Thats what i did.
There is only one problem:

CString can be used as any "const char *" because its a C++ class which has
an overloaded casting operator.
BUT the aw_string_set are c style functions, and c style programmers do not
care about the "const" attribute.

this prevents a c++ compiler from letting you use CString as the argument
for aw_string_set.

Roland might change his include file (and his dll source as well) to use
"const char *" whenever he does not need to change the supplied string.

you need a work around which casts the CString to (const char *), and then
to (char *). (assuming, and thats the bad part of it, that aw_string does
_not_ change the supplied string)

that would look like
CString m_loginname = "Daniel";
aw_string_set((char *)(const char *)m_loginname));

and since that looks very ugly, you hide it using a define.

#define AWSTR(param) (char *) (const char *) param


Heres the part from my bot code which sets the login parameters, directly
from the member variables created in class wizard.

aw_int_set (AW_LOGIN_OWNER, m_citizennr); // Faber citizen number
aw_string_set (AW_LOGIN_PRIVILEGE_PASSWORD, AWSTR(m_privilegepw));
aw_string_set (AW_LOGIN_APPLICATION, AWSTR("Faber Bot App"));
aw_string_set (AW_LOGIN_NAME, AWSTR(m_name));


If you do this in the message handler for a button on the dialog, remember
to call UpdateData(TRUE) first to make sure the class members are in sync
with the dialog controls.


>Also if possible is there a way to have it print the log (like the printf
>lines) to another edit box? (IDC_LOG_EDIT) and put errors into popup
message
>boxes, since it's not a console app....

Sure, create an edit box control on your dialog window, assign a member
variable to it of type CEdit (note its a control association, not a data
transfer) and name it m_status, and add a function (using ClassView, or do
it your own) like follows:

void CDanielDlg::Print(const char * message)
{
CString outmessage;
outmessage.Format("%s\r\n", message); // note the \r which is important
in edit fields
m_status.ReplaceSel(outmessage); // add text to current cursor
position
int start, end;
m_status.GetSel(start, end); // get selection position
m_status.SetSel(end, end); // remove the selection and set cursor at
end of it
}

(taken from the Daniel bot, if you ever ran into it :) i usually carry it
around when i am in aw )

you can call it with constant strings, not const strings or CStrings,
whatever you prefer :)


If its not enough to have errors logged in there, use the MessageBox system
call for it. Inside a window class using MFC the function prototype is

MessageBox(const char *message, const char *title="Error", int style=MB_OK)
so try

MessageBox("Could not log in to AW universe");

for simple boxes or

if (IDYES == MessageBox("error occured, continue?","Please select",
MB_YESNO))
// continue here
else
// do not continue


hope it helped :)

Nope, its about as difficult as having a real good argc argv parser
(including options with arguments separatet by quotation marks and reversing
and stuff :) )

GUI used to be very complicated (win16 API), but MFC helped alot.

This is really unix background :) Windows things are a different world.
16bit-windows never had a reall command line or at least no documented argc

dialog based bot.... questions & errors

Oct 16, 1998, 3:27pm
The attribute "const" is in c is almost code flavour only. the c compiler
does not really care.

in c++ it has become very strict. you can't change what is const and you
can't use something that is const as something that is not const, unless you
cast to it (so that you know whats going on).
and you can depend on the fact that people wont change what you supply as
const.

so i'd say that you actually change your (char *) parameters in your aw.dll
and aw.h to (const char *). recompile it to see if the c compiler complains.
(if you use c++ in there i am quite sure it will, since your code is adapted
to "char *" and not "const char *.)

if it does NOT complain, you are on the safe side and your interface
description is more safe and more accurate for c++, and in that case
DEFINETELY change aw.h in the next sdk build :)

if you declare a function as void, it MUST not return a value under c++ ( c,
again, doesn't really enforce this).

so remove the return line, (or at least the value to it, change it to
return; )

for the linker errors, make sure to adapt your project settings to inlude
"aw.lib" as additional libraries in the linkers tab (both for release and
debug version).

you forgot to add the function to the class declaration in the corresponding
header file. this is what your class wizard does for you usually, unless you
are adding a function yourself.

open "AWTeenBotDlg.h" and look for the CAWTeenBotDlg class declaration..

in there you find several function and variables definition already,

add a line saying

void Print(const char *message);

to it.

dialog based bot.... questions & errors

Oct 17, 1998, 12:46pm
PCWizard,

i have examined your code and fixed a couple of things in it.

first of all, your bot programm could not log in because you didn't call
UpdateData(TRUE) as i mentioned in my post, which caused your member
variables to be empty and your bot trying to login using "" as the name,
resulting in "name to short" error reason code.

you could not see the error message because you didn't use the Print
function that was supplied by me, you still used printf().

your programm exited immediately because you called exit() after error
output, which is something you don't do on windows.you return from the
function instead.

i fixed all this, and it runs just fine now. I startet it and it send itself
to awteens world. i could not enter there using AW browser (access denied)
so i sent my own bot after yours, and i could verify that awteensbot
actually appeared there.


additionally i fixed the following things:

- I changed your log output edit field to include the "multiline parameter"
- the aw_init and aw_term / aw_destroy moved into the application class
because thats where they belong unless
you run multiple bots (in thats case aw_destroy is need for each bot)
- i added the code lines to save your dialog contents into an ini file. the
windows api creates and maintains an "awteenbot.ini" file now in the windows
directory
- i gave an example for parameter checking when using CString
- i included "aw.lib" for debug compilation

and, most important
- i removed the aw_wait(-1) from your bot startup function. instead I added
a timer which is called by windows every second, and in the timer handler it
calles aw_wait(10). that results into your GUI and your bot beeing
responsive.

all my changes are marked with "WAK"

SDK apps tied to other programs ?

Oct 15, 1998, 7:50pm
The main use for voice recognition software is that you use it to type. type
in word processors, in excel sheets and in whatever.

that means almost every software of this kind is able to input characters as
keystrokes into other applications.

since you can write a GUI bot for use to talk and listen inside aw, you can
easily have TrueVoice or ViaVoice or whatever they'calles talk through a bot
AND, of course talk in the AW browser itself.

no need for transfer using a text file.

A bit of help :)

Keep an eye on the windows api functions

GetPrivateProfileString
GetPrivateProfileInt
WritePrivateProfileString

for own .ini files the best you can get :)


e.g.

WritePrivateProfileString("section","tag","value","myfile.ini");

creates or changes an "myfile.ini" that reads

[section]
tag=value


and GetPrivateProfileString would be able to read that into a buffer or
CString

Number of logins per owner

Oct 17, 1998, 10:17am
Which instance determins the number of bots one can run ?

My bot allways failes to spawn more than 2 more bots, 3 in total, and it
fails at the aw_login,
which means that is a universe limit. is that correct ?

i am sure its good that the number of bots is limited, but e.g. for the beta
world, it would be nice if the limit was much more, since it would allow for
more bot testing :)

imagine 10 bots controlled by one programm, you could have a dance
performance or sth similar :)

3 bots don't even match spice girls (well, by now they do since spice girls
are down to 3 :) )

User counts

Oct 18, 1998, 7:57pm
Which means that SDK bots do not count.

Hambots do count. and you almost ever run into one :)

Its quite funny to stay at Beta GZ.. every 5 mins some hambots appear,
mumble something, chase each other and dissappear. no owners in sight :)

Bot logging...

Oct 22, 1998, 7:14pm
Don't use fopen everytime you write a log line unless you use fclose() in
the same function to close the file again.

its more efficient to keep the log filehandle variable at global scope

FILE *logfile;

main()
{
logfile = fopen ("mylog.txt", "a"); // "w" overwrites "a" appends
to existing log
if (!logfile)
{
printf("warning: can't open logfile for writing. no log is written
in this session\n");
}
aw_init
aw_create
aw_login
aw_enter
set position

set chat callback.

while aw_wait {
}

aw_destroy
if (logfile) fclose(logfile);
close();
}

chat callback
{
get chat message
if (logfile)
{
fprintf(logfile, "Saw chat '%s'.\n", chat message);
}
}

Bot logging...

That's ok :)

confused...

Oct 23, 1998, 5:49pm
The loop breaks if the aw_state_change returns a value not equal to 0, which
means when you run into an error while setting the new avatar position.

I think bots move as other people do, they just need fewer repositioning
steps which usually means that one repositioning is sufficient. the aw
browser translates a sudden repositioning into a smooth move, (or a fast one
if you move far in a short time).

so the decision if you walk or glide is actually made in each users browser,
therefore you can't really influence it (and you don't want to break down a
move into several small steps because of that anyway :) )

Roland, if my observations are wrong, please correct them :)

Walter
