utbot-devel Mailing List for Unreal Tournament Java Bot

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Now that SourceForge supports it, does anyone have any concerns with 
moving away from CVS and into a Subversion based repository?

Anm

Did Gamebots ever wind up getting ported to ut2k3?  My group is thinking
of moving to ut2k3 next term, and we're wondering if the code works as-is
or needs any changes.

I have added Moshe Sayag as a developer on the utbot project. Moshe says 
that he has uncovered some bugs in the code and fixes. I asked him to 
check the bugs in through the bug tracking system in sourceforge before 
commiting changes.

Hi,

I'm currently trying to hook up an AI infrastructure at my lab to Unreal
Tournament using Gamebots.

One problem we're having is handling callbacks.  Our system expects to
be told when a primitive action (e.g. walk) has been completed, and
whether it has been completed successfully or unsuccessfully.  It appears
that this has not been built into the Gamebots network API.

We have just started working with UT, and are wondering if anyone
has worked on this problem before.

Can you give us an example/stack trace of the crashing you are talking 
about.  To my knowledge, the system has been fairly stable, and I never 
had significant problems when I wrote it forever ago.

That said, your other alternative of writing straight to GameBots is not 
difficult.  As long as you get the line endings correct, the protocol is 
very straight forward.

Hi,

I'm trying to gather information about Gamebots and Javabots.  I'm working
on an AI project at Georgia Tech and we're looking to use the UT engine to
create virtual worlds for our agents to populate.

It seems that Gamebots has been used by several people outside of USC, and
we are interested in using it.  The professor who I'm working for has
created a reactive programming language which targets Java; it seems like
Javabots was created to facilitate hooking up systems like ours to
Gamebots (which is turn was created to facilitate hooking up systems like
ours to UT).

But we've have had some trouble using the Javabots API (it keeps on
crashing), and we haven't found any robust bots on the web that use it.
We're wondering whether we should use this software or have our program
connect up with Gamebots directly.

Hi Nishant,

After installing the patch, you must download the gamebot mod:

http://easynews.dl.sourceforge.net/sourceforge/gamebots/gamebots-2001Jun
08.tgz

and also place the extracted files in the UT/system folder.

Ryan,

Thanks for introducing yourself.  The bulk of the BotAPI and FriendlyBotAPI
development is being done at CMU, but we rely on users to report bugs in
a way that allows us to reproduce them here.

So by all means, please report bugs and suggest improvements.  We may be 
sometimes slow to integrate everything into the main package, but it is mostly
so that we don't break existing functionalities that others are relying on.

We will be releasing a bug-fix to BotAPI soon, as Jared has mentioned.

Hello,

As Andrew mentioned in this message, we have created a sourceforge
project and got permission from Andrew to redistribute his code (our
modified version) as part of it. We made some modifications mostly to
handle more agent actions as convenience methods within the Bot class.
You can find a release of our code as well as a listing of the updates
that we have made at:

http://utbot.sourceforge.net
And you can download releases or view/checkout from the CVS repository
from the project summary at:
http://sourceforge.net/projects/utbot

Since this is my first posting to this listserv, let me introduce
myself, my name is Ryan Rozich and I am a graduate student studying
multi agent systems at Texas A&M University. I started looking at the
Gamebots for Unreal project this semester as an idea for a class team
project this semester. The short-term goal of my temmates and myself is
completing this project for our Multi-Agent Systems class this semester,
but I will probably continue to be active in this project after the
semester is over. Others have posted some inconsistencies/bugs between
the Network API document and the messages that are sent to bots to this
list, we have also noticed some of these and have a few questions that
we will post over the next few weeks. Hopefully others will have
encountered similar problems in developing bots and can provide help.

Please let me know if you download our version and find these changes
useful or if you have improvements (or suggestions/ideas) for the client
architecture that we can add.

Cheers,
Ryan

Level mapping is exactly the purpose I had in mind when I wrote the Java

project, I recently received an email regarding interest in supporting
the JavaBot and client architecture.  For now, though, the source is
available as part of the Java Client under a file called
ExampleBot.java.

Unfortuneately, this depends a lot upon the map, the mods loaded, and
the game type.  No list could be complete.

That said, we should start listing the objects and attributes of the
common items for each game type.

I don't think so, but I don't know what results you'll get either.  Run

I have created a release for our project that can be downloaded from our
project site on sourceforge. They are in zip format and come in three
varieties:

Source only - docs and jar can be built using the ant build script
Bin - includes the executable jar file and docs
All - includes everything (source, jar, docs)

I also put together a simple we page for the project
(http://utbot.sourceforge.net) because there were a few things that I
wanted to put on there (links, screenshots, API documentation, etc).
Joe, you said that you were working on a simple design and something to
say on this page. I wasn't trying to do your work for you, I just
thought that it was better to have a little something than nothing there
- please upload your version when you are ready and try to figure out a
way to incorporate the stuff I already have on there please.

I think that we are ready to start doing some real work now. We have
gotten over the hurdles of learning the Javabot API and gamebot protocol
(almost) and have the sourceforge stuff in place so that we can all work
on the code. If we could get by without commiting to a certain agent
architecture over the next couple of weeks I think that would be good,
since I still feel that our goals for this project aren't well defined
yet. We can begin to think of ways to implement simple agents that solve
simple problems and work our way up from there. That's my view of the
way to proceed, does anyone disagree? 

I will be busy over the next few days with other classes/projects and
stuff so this is all I can do for a little while at least. I plan on
sending a message out to the gamebots listserv soon to let them know
what we have been working on here. If either of you are in Bright
tonight, you can find me in my office.

Cheers,
Ryan

I'm not sure if either of you are using netbeans for your IDE, but it is
my favorite (and it is also free) - especially since it has cvs support
built right in. There are a few hoops to jump through in order to get
netbeans cvs features to work with the ssh method required for
sourceforge. JCVS, which netbeans uses as its internal CVS client, does
not support this. There is a way to get this to work though and a HOWTO
is posted at

http://www.netbeans.org/articles/sourceforge.html

I went through this and found that it was helpful but incomplete. After
stumbling around to figure out what was missing and getting it to work
myself, I've written up an addendum to this document and attached it to
this e-mail in case either of you want to do this. This is only for
windows, since that is what I am currently running. Joe might be able to
add to this document describing how to do it in linux. I might submit
this to netbeans as an addendum to that HOWTO, so let me know what you
think.

Cheers,
Ryan

If you define src as the module name you will just check out the src
directory and nothing else (i.e. the documentation). If you just specify
'.' (no quotes) as in my example it gets the whole thing. Yeah I think
that it is nice, but if we wanted to add another module to the project
(although I don't think we will) I'm not sure how we would do it.

Before I got your email, I was browsing the cvs repository, and I
was stumped.  I couldn't figure out how you checked it into the
root.  That is simply amazing! 

The first time I imported code into a cvs, I accidentally put it in
a subdirectory of a module.  I had no idea that you could do it
"your" way.  Does this mean that our module is named "src"?

After many trials and tribulations getting SSH and cvs installed on my
windows machine (no, joe - I don't know why I didn't just reboot to
linux :) I finally figured out how to check out our code from the
sourceforge cvs. I did something that I did not want to do, namely to
check in my initial source code into the root directory of the
repository. I would rather have left the ability to check in other
modules at the root level, but I don't know how to reverse this and
think that we will end up using only one module anyway. 

Here is how to work with our project on sourceforge:
1. Set up your system for cvs using ssh (look on the documentation of
sourceforge for this). I am using a windows command line cvs client, not
WinCVS.
2. You must first log into the cvs shell to create your home directory
using:
>ssh -l <sourceforgeid> cvs.utbot.sourceforge.net
(this little piece of advice is worth hours of frustration for me)
3. You can check out a working copy of our code with:
>cvs -z3 -d:ext:rya...@cv...:/cvsroot/utbot co .
of course, replace ryanrozich with your ID

After that, you can do commits, updates and whatever other operations
you want by simply going to the directory and typing
>cvs update
Or whatever other command that you want

Finally, do not be tempted to go the easy route and use the anonymous
:pserver method of checking out code. This will allow you to check out
and update (I think) your module but you cannot commit any changes. You
must use ssh and the :ext type on your cvsroot.

Now you can check out the code and start making any changes that you
want.

That's all I got,
Ryan

I have made an initial check in of the source to sourceforge

Even though I set it up differently from what I thought, I agree
that getting my own email back is better.  That way, I have a
complete, easily accessible archive of activity on the list.

One little point, though.  There should be a "List Reply" option
on your email program, which will follow the "mail-followup-to"
header.  If your email program does not have this feature, simply
use the Reply to All button.  This will duplicate the message to
the person you are replying to, but it generally is easily
filtered in procmail or ignored.

Your solution of using the entire name java.util.Map, is not as
unacceptable a solution as it first appears.  This is the easiest
solution, and IF you are at all worried about backward
compatibility, you would want to keep the name.  For reference,
see the javax.swing.Timer and java.util.Timer classes.

On the other hand, since this is only in the newest version, it
probably doesn't have any real backward compatibility concerns.
I'd suggest just changing the name, and letting other people deal
with it.

We should try to avoid commonplace names for all of our classes,
if possible.
