Try running the roborumble.sh in each of your client folders and manually run a battle against DrussGT. If it gets banned or doesn't run it should be fairly obvious, and you can test which one it is before deleting and re-downloading. It will also help confirm what the problem is.

How do I force roborumble to execute DrussGT battles?

I think he means robocode.sh, as in just run Robocode from your RoboRumble directory and run a battle with DrussGT, maybe against one of the bots we saw a zero score for. With any luck, you'll see the problem in action and get an idea what's going on.

doh... yeah, what Voidious said. Run Robocode from the rumble directory and see if DrussGT gives errors.

I'm going to be without internet for the next few days so if someone could re-release 2.4.10 as 2.4.10a once this is sorted out I'd be much obliged :-) (2.4.10 is just some minor bugfixes, I'll add details when I'm back)

You could also add jk.mega.DrussGT* to the EXCLUDE field in your roborumble.txt, if that's the only bot you're having problems with. But it would also be good to try some manual battles and see what's going on. After that I can repost DrussGT 2.4.10.

jk.mega.DrussGT* was excluded for now, I'll post a reply when I find out why Druss was having issues.

Thanks for the repost while I was away =)

Hmm sorry mates.. looks like something is wrong with my client .. Druss get allways 0 battles ... maybe i can check what it is going on :(. Maybe you should rerelease the last version too. Sorry for the inconvenience.

Take Care

Well it turns out that the same is happening on my mac client. No errors or anything it just drops the battles while all other battles are fine. Not sure how but looks like an issue with unix/linux? Maybe i can find out more - and will have a look at your bot in the visual client.

Hmm very strange ... this is the output:

If i start the match with "paused" game and make a single step, everything is ok and he finishes the match like he should. But as far as i start the match just normal it gets instantly disabled. Do you have some heavy object loading at the start or something?

I figured it out. I was also getting 4-6 skipped turns on start, but not enough to disable the bot. My FastTrig class wasn't being initialized until the first call to it. This might be somehow related to Java's lazy class loading. I've uncommented the hard initializing the FastTrig now in the main DrussGT class and I'm not getting any more skipped turns. Could you try with the old 2.4.8 to confirm that the problem doesn't happen? Thanks

Hi mate. 2.4.12 works fine for me.

Hmm looks like your bot give me a hart time :) ....

Maybe you can find the issue with this little error snippet. Before this break i had a couple of fights where DrussGT did well, so it looks the original issue is solved.

Every time I get the "invalid robot or team" error, I do the following:

1. run RoboCode in my rumble directory. (That opening splash screen will take forever with so many bots. be patient.)
2. do Options -> Clean robot cache (this one takes a while too.. watch the terminal screen and wait for "cleaning done")
3. close

That clears up lots of weird rumble issues for me.

I guess you can just remove the "robot.database" file in the robots/ directory and the next time you start your client it will be rebuild. At least this is what i do from time to time.

I'm not sure what that is, however I did add some things to the static initialization, maybe it's too much now? I've gone back to 2.4.10 with just the FastTrig fix, let's see what happens.
