Old Wiki

I presume all older issues are not valid anymore, otherwise you can find them on /StartingWithRoboRumbleOld or put them here below again.

Sweet. Much easier now thanks. How can I control how many battles are run at once? Or should I just setup a for loop in a batch file for that? --Miked0801

  • Halfway the file "roborumble.txt" you'll find "NUMBATTLES=xx", there you fill in the number of battles fought before uploading results and quitting robocode. In the batch-file I have made an infinitive loop so my client can run unattended all night. -- GrubbmGait
  • (Edit conflict) There are .txt files for each type of rumble - roborumble.txt, meleerumble.txt, and teamrumble.txt - in the 'roborumble' directory. The "NUMBATTLES" controls how many are run before uploading, "BATTLESPERBOT" is the minimum number of battles a bot needs before it stops getting priority, and "USER" is just to identify yourself in the logs and such. I have mine with "ITERATE=NOT" and I do use a shell script that loops to keep it running. -- Voidious

this bash script will be good for unix "roborumbler". Run forever battles, it catch standard and error stream and put it to a file in the directory ./log/tempNUMBER_OF_BATTLE.txt (the script have to be in the roborumble directory). For Linux: save it to a file in the roborumble directory, right click and set the file executable, create a directory called "log", then run the script from shell:


echo #  new line
while [ "$var1" != "fine" ]     #  forever
  let "count=count+1"
  echo "battle n: " $count
  sh &> ./log/temp$count.txt

exit 0

p.s.: it's very useful for catch error, someone can traslate the script in windows's dos? Asdasd

Wow - is 256MB still the default for the rumble? Why not at least 512, if robocode's default itself is 512? -- Simonton

I'm not sure - maybe because the GUI takes a lot of memory? -- Skilgannon

Ehh, the GUI shouldn't, not compared to many adaptive bots (particularly log targeting). Personally I always set 512MB in the rumble, and the only time I've had an out of memory problem with 512MB was when some particularly memory-heavy team (can't remember which one) was going. Personally I'd support defaulting to 512MB, at least for teams/melee, if Fnl is listening :-) -- Rednaxela

Can someone please zip a new update, i've unzipped the archives above and still get a ton of "Ignoring xxx..." message because they weren't download...thank you! (or even better someone start a new repository and put the zipped bots there...) --Starrynte


I didn't know where to post this, but I guess the talk section is always good enough. I created an Java Application called RoboRumbler to help controlling the resources RoboRumble uses. It's basically an application to let me work and run RoboRumble at the same time, I further explain it in it's page if anyone is interested. --zyx

Hmm, I'm curious about this. How does it account for the fact that RoboRumble is highly sensitive to the amount of CPU allocated to it? (i.e. other apps taking lots of CPU can make bots skip turns and potentially give very wrong results). If this limits the CPU allocated to RoboRumble, does it correctly make sure the constant for the time robots get per turn is increased suitably? (P.S. on the new wiki you can use --~~~~ or the signature button to sign your messages with time/date easily. Personally I'd recommend it because it makes it possible to look back at conversations and know when they happened. :)) --Rednaxela 21:45, 26 November 2008 (UTC)

Right now the application is not intended to work with CPU intensive applications, it basically runs them in the same way as they would normally do, but allows you to run then from time to time, and then forever by itself again and stuff like that. So you could be working in the machine, but not hogging the CPU yourself, you can set it to have a few battles and then sleep for 20 minutes. You could be writing some code(I did it to work on my thesis in the mean time), but not execute it until the RoboRumbler goes to sleep. Then you would have those 20 or any other amount of time to use the whole CPU when no rumble battles are running, so you could compile and test your application, and then, when the rumble is about to start again, you lower your activity. And when you are heading to your bed, set the sleep time to 0 and let it rumble without stop.

Hopefully it will grow to a system that doesn't need for the user to be careful, but right now is the best I have. I was doing the same thing but manually, I ran the rumble battles while I was writing stuff, waited for it to finish so I could ran my application and then set the rumble again. But in no moment my idea was to really lower the CPU usage for RoboRumble during battles, but to have some deterministic break times when I could use the computer. (P.S. Thanks about the --~~~~, I saw it before in your post, but thought you wrote it yourself, and seemed like to much work) --Zyx 23:44, 26 November 2008 (UTC)

stable rumble client

Are the stable rumble client 1.5.4 and, 1.6.0 or someone have tested the new robocode version? --lestofante 15:44, 10 December 2008 (UTC)

I know is stable (some earlier 1.6.1.x versions were bad), with a minor aesthetic bug that it sometimes spams the "Round 31 initializing...." to stdout but that doesn't affect the battles or the uploading so it's good for RR. Additionally, as of the ITERATE option works properly again, so external loop scripts shouldn't be needed. I plan to test 1.6.2 Beta 2 some time but haven't done that yet. --Rednaxela 20:10, 10 December 2008 (UTC)


I have RUNONLY=NANO in meleerumble, yet it still runs battles with tons of non-nano bots. 1) will this affect rankings improperly 2) how do you get it to run only runonly is supposed to do (using version --Starrynte 00:59, 3 April 2009 (UTC)

  • I've never tried these modes so don't know how well they work. I'm pretty sure RUNUNLY=SERVER is the only way to guarantee full pairings, since that's the mode where the client uses priority battles sent by the server. Also, I think the client considers nano pairings in melee to be any matchups between two nano bots, even if there are other sizes in the same battle -- which means you don't need a battle with 10 nanos in order to get meleenano results. That's why ntc.Opposite's nano results are up to 600+ already. --Darkcanuck 01:18, 3 April 2009 (UTC)

Questions from Positive

Hey, I'd like to contribute, but need some help. I've followed the instructions on this page (I used version But what's the correct configuration for meleerumble.txt for Darkcanuck's server? Also: Can I safely quit the roborumble client when I need my CPU back? Is there something else usefull to know/do before running? :) --Positive 16:40, 17 July 2009 (UTC)

I think you can just replace the domain with, but my full URLs are:

Yes, run the client as much or as little as you like, of course. =) Hmm, one issue comes to mind: the bots using Robocode Repository ids will fail to download, I think. I fixed the URLs on the 1v1 list and some on the Melee list, but still lots of ids there. Running the 1v1 client to download bots first might get a lot of the missing ones. I'll try and get that fixed today.

--Voidious 16:58, 17 July 2009 (UTC)

Hrm, well it seems like it should work, with Portia it did, or did you have to add it manually? I could make a script and change all lines with "ROBOTNAME,NUMBER" to "ROBOTNAME," --Positive 17:11, 17 July 2009 (UTC)

Hmm, now I'm not sure, really. I don't think I grabbed Portia manually. Feel free to update the list yourself, if you want, I did exactly as you said using regular expression find/replace in my text editor (TextWrangler). I'll get to it later today if you haven't yet. --Voidious 17:24, 17 July 2009 (UTC)

Hmm, I tried it, and it's not that easy. For example, the pure converted form of TheArtOfWar changes from "tzu.TheArtOfWar 1.2,689" to "tzu.TheArtOfWar 1.2, 1.2.jar". But I don't know what the actual download link is. (It's not "tzu.TheArtOfWar_1.2.jar" either). Any downside to just activating roborumble and seeing what happens? --Positive 17:54, 17 July 2009 (UTC)

It seems TheArtOfWar was an exception, I'll replace the original with the new in a few moments. :) --Positive 18:06, 17 July 2009 (UTC)

Cool. I'm not sure what's up with that, but I was thinking, "I swear I used that same format for the 1v1 list and it worked." =) Also, Darkcanuck was kind enough to post all his rumble bots here: [1], so you can grab any missing ones. (I didn't mention before because it's not a great way to get all of them.)

One of us should post an updated .zip of rumble bots as a base point for new RoboRumblers... there are a few old ones posted around the wiki, but I can never remember where. The hurdle with that is cleaning out all the multiple versions of certain bots before zipping.

--Voidious 18:14, 17 July 2009 (UTC)

I found the .zip here: RoboRumble/Starting With RoboRumble. That zip is pretty complete, the message I got only showed a few missing:

So only a few are actually missing at the moment. No idea how much old ones there are. Anyway the rumble server has gotten 3 battles from me! Thanks for the help. :) --Positive 18:34, 17 July 2009 (UTC)

Feel free to replace links in the participant lists to those on the rumble server (if they exist). I'm not planning to remove any of those bots, and will periodically copy new ones over from my client. --Darkcanuck 18:53, 17 July 2009 (UTC)

I'll see if I can post new versions of the participants zipfiles for one-on-one and melee this weekend. Last time I had trouble getting it online as my webspace (20Mb) was full. --GrubbmGait 13:00, 18 July 2009 (UTC)

You may contact me or Voidious to put them on my or his webspace. I don't know how much Voidious has, but I have around 1.1GB free. » Nat | Talk » 14:33, 18 July 2009 (UTC)
Just curious, isn't it possible to upload the zipfile to this wiki? It seems the right place to put it. A complete zip for one-on-one would be approx 18 Mb, for melee approx 8 Mb. Just need to bring up my rusty Perl knowledge so I don't have to sort out the current participants manually. --GrubbmGait 11:30, 19 July 2009 (UTC)
You must have access to this server to do that. I don't know if you have it or not. Because the wiki only accept .png, .gif, .jpg and .jpeg files. I agree with you that the wiki is the right place to upload them; but if you can't, feel free to contact me, my email is on my user page. » Nat | Talk » 11:41, 19 July 2009 (UTC)
It's not possible for me, max download is 2Mb. Melee is 6.5Mb, full one-on-one 16.8Mb. I'll try to put it on my own space first. --GrubbmGait 12:51, 19 July 2009 (UTC)

Friendlier Starting?

We've always had this problem, but now I'm the victim instead of the perpetrator! "Getting Started" really should be ... let's say three steps at the most: 1) Install robocode in a fresh directory. 2) Apply this patch (that takes care of config). 3) Download these bots (all in one file). And really, (2)'s config should be packaged w/ robocode as long as the rumble itself is. In the mean time, perhaps update the instructions to point the config files to the correct server? I followed them, and unless I missed it every time I read through them, it never says to change the URLs to something other than What should they be? I tell ya - a guy just wants to help out his old community and has to go to all this trouble ... --Simonton
