EmptyBot will not run

Posted by phry on Tue 12 of Oct, 2010 14:18 CEST
Hi

I'm using Pogamut v3.0.11, whenever i try and run the emptybot example i get an error saying that the component bus is stopping. Anyone have any ideas why this isn't working. Below is the error that i get when i run the code.

Hi phry! Welcome to the forum :-)

You do not have GameBots2004 server up and running on localhost:3000

>> Cause=ConnectionExceptionLogCategory(Connection): java.net.ConnectException: Connection refused: connect (localhost:3000)

Before you may start a bot you have to start the GB2004 server first. You may do it either via Windows Start Menu item called "Start UT2004 DM server" or via UT2004 itself by starting a custom game type called GameBots2004.BotDeathMatch.

I recommend you to watch tutorial videos from here: http://diana.ms.mff.cuni.cz/main/tiki-index.php?page=Documentation

Good luck! And don't hesitate to ask another question!

thanks for the quick reply :-D

i've started a server but i premuse it can't be setting itself up properly. I can see the server in netbeans and change the map which i thought ment i must have a connection. when you run the server from the bat file how do you know if the server has started correctly? I have been getting errors saying that there was an error moving Save.tmp to Packages.md5 but this seemed to go away once i started the bat file using the "run as administator" function in vista.

Ok,

so the situation is that:
1) you may connect to the server inside NetBeans, so it shows you a map
2) the bot can't connect

My guesses are:
1) it is a firewall problem (have you allowed anybody to connect to UT2004.exe process ?)
2) some other process may block port 3000

Try this:
1) check the console window of the server, the last two lines after the start should be:
BotServerPort: 3000 ControlServerPort: 3001 ObservingServerPort: 3002
START MATCH

2) if BotServerPort is 3000 than you may check it using telnet, go to the command line (Start menu -> start -> cmd) and try:

type: telnet localhost 3000

then you should see a line:

Connecting to localhost

then it disappears and the GameBots2004 should greet you with line

HELLO_BOT

type: READY

and GB2004 will send you a hell lot of info about the environment

If this fails (i.e., the telnet won't connect or the line does not appear), than the server didn't start properly.

... btw ... if you do not have telnet, you may added easily to the OS, follow the instructions here: http://www.tech-recipes.com/rx/1793/vista_install_telnet_client/

------------

Have you succeeded? Does the GameBots2004 greet you?

Best,
Jimmy

The telnet doesn't work when i use:

telnet localhost 3000

however it does work when i use

telnet 127.0.0.1 3000

(my connection to the server through netbeans also has to use 127.0.0.1:3001 instead of localhost:3001 - could this be part of the problem?)

Wow,
so the problem lies in the "localhost" resolving.

It seems that your OS does not translate name "localhost" to 127.0.0.1 which is pretty bad.
... and correct, that's why the server is working but bots do not.
I guess we (Pogamut) should not be using "localhost" for bots connection but there we are... we have to work it out what we've got now.

Try: ping localhost

If that fails, than I suggest you to resolve the naming issues, something like: http://bytes.com/topic/asp-net/answers/645776-http-localhost-not-resolving-vista-ultimate should help.

Best,
Jimmy

It does let me ping localhost. So the problems seems to be when i ping a port on the locahost. Any ideas? :P

Appreciate the help :-)

Hmm, we did not test it yet, but this should also work.

Try to set up system property:
pogamut.ut2004.bot.host=127.0.0.1

The system property should be picked up by the bot (as default this property is "localhost").

Please, note that you will probably have to restart NetBeans or the whole system after you add a system property to Vista.

Best,
Jimmy

Glad to help!

Truly, don't hasitate to ask, we're trying to resolve every issue posted here!

Nevertheless, that problem localhost127.0.0.1 may reappear in other programs too, so watch out!

If you're going to use UT2004ServerRunner or UT2004ObserverRunner you would also need these properties set:

pogamut.ut2004.server.host=127.0.0.1
pogamut.ut2004.observer.host=127.0.0.1

Best,
Jimmy
