I took the freedom of erasing all my old and deprecated stuff which just cluttered this page :) Please inform me if this is "bad" behaviour here, then we can restore it!

I also have some questions, and wonder if there is a good way to talk to more experienced Robocoders, like some IRC channel or similar, or a good place to post these questions?

While I'm at it, I wonder how to get LiteRumble running. I downloaded a "superpack" from the talk page of LiteRumble, but it was for for some 1.7.x version, and someone mentioned to update the client to the newest version. So could I just create a new folder for the most recent robocode, copy all the bots from the superpack there and change the roborumble settings? What's the most elegant way? :) And do the bots update automatically? I don't want to be just trying it out, since I fear I could destroy something by doing this.. --Kenran 19:38, 16 April 2013 (UTC)

No problem just clearing your talk page, it's up to you. You could also archive it, eg: Archived talk:User:Voidious 20110909. I think just posting to your talk page, or the talk page of whatever topic, is probably the best place to ask questions, then everyone can see it and respond. About chatting, we don't have an IRC channel, and it might be tough to sync up since a lot of folks are geographically spread out here. I'm my handle on AIM or at gmail for GTalk if you want to try to catch me on IM - a few of us chat that way sometimes.

In 1.8.1.0, Fnl updated the RoboRumble configs to point to LiteRumble. So yeah, I think you can just make a fresh install of 1.8.1.0, edit your name in roborumble/roborumble.txt, and start up roborumble.sh (or melee/team/twinduel .txt and .sh). It checks the participants list on the wiki and downloads missing bots, but copying the set from the superpack will save you some time. I also like to set ITERATE=NOT in the .txt file and have the .sh file setup to loop, and that's how they are in the superpack, but I'm not sure you really need to futz with that. You can also set UPLOAD=NOT in roborumble.txt to run without uploading, if you want to be extra paranoid about messing things up on your first try. :-) Let us know if you hit any snags. --Voidious 00:11, 17 April 2013 (UTC)

As a quick note, as far as downloading the complete set of bots, what's more up to date than the superpack is http://robocode-archive.strangeautomata.com/participants-latest.zip, which is automatically updated hourly to contain the complete set of all bots in the rumble. --Rednaxela 05:44, 17 April 2013 (UTC)

Thank you both, it worked out perfectly! Now I can go on about recreating my last bot... lost all my code there and I could beat myself for not including it in the package in the first place... ;) Maybe once I encounter some problems, I will structure this page to make an own category for questions and, hopefully, answers :) --Kenran 08:25, 17 April 2013 (UTC)

Another short question: on the top right of the robowiki, there's always 'new messages (1)', but when I click on it, it says there are none. Is this a bug? And how could I fix this, by clearing browser cache or stuff like that?

That happens to me a lot too. I've just learned to ignore it. I assume the problem is on the wiki's end, so I doubt clearing your browser cache would do much good, but go ahead and try it if you want to.

Maybe we can just get rid of that... Mine says 2416 and crashes with out-of-memory when I try to click it. :-P --Voidious 21:15, 18 April 2013 (UTC)

-* As you can see <code>aimed</code> is superfluous at the moment. I tried to make the bot faster by only calculating predictedPosition at moments where I actually want to shoot. But I can't seem to handle this: I wanted to do sth like <code>if (getGunHeat() > getGunCoolingRate()*3 && getRoundNum() != 0)</code>, then predict and set <code>aimed = true</code>, and finally fire if <code>aimed == true && getGunTurnRemaining() == 0.0</code> (and set <code>aimed = false</code> again). But that doesn't work, at a certain point it just stops firing at all then :-/
-* I don't understand why, e.g. versus Walls, it can't handle the movement in the edges: it seems to predict the right "position" but at the wrong time, so the bullets just impact before Walls is at that position. Any ideas why this could be the case? Maybe sth with my predictPosition algorithm.
-I hope, my code is not too sloppy, as I mentioned, I'm not a very good programmer. Anyway, great site, I wouldn't have been able to get any kind of targeting working without it :-)

-What is the propose of <code>getRoundNum() != 0</code>? That means it won't fire in the first round.  If you remove all reference to the getRoundNum() == 0 or getRoundNum() !== 0, I think it will perform much better.
-Actually I would say, don't use the PMC robot as a codebase, as it is very optimized to the PMChallenge. Try to read the robot with normal PM, e.g. Waylander, before. If you can't figure out what is behind the shrunk code of Waylander, feel free to ask again. {{Unsigned|Nat}}
