AI Development Discussion and Feedback

redrum

Hmm that is pretty strange for Russia turn 1. They should almost always attack something at least the German navy and usually Ukraine. I ran 5 quick test games of just russia turn 1 and every time the Hard AI attacked those 2 and sometimes Manchuria. Here is an example: Russia1.tsvg

Its possible there was some kind of error or that the AI hit some kind of weird edge case or something. Can you try just starting a new game against the Allies AI again to make sure it isn't happening every time for you?

Thanks for reporting the errors and you can see your reports here (this is a new reporting feature): https://github.com/triplea-game/triplea/issues. A few of them we are aware of and need to fix before putting out a new stable release but we'll take a look at them all. I think most of them are harmless errors and shouldn't impact the game or the AI play.

Thanks for the UI feedback as well and I'll highlight that over in the unit scroller thread. Its a new feature that allows you to scroller through all your unmoved units (can be helpful especially on very large maps).

@redrum so should i try global or a simpler map?

redrum

@ubernaut Global is generally fine though the AI's diplomacy on the map is fairly limited and has a decent amount of randomness. It also doesn't understand NOs. Other than those 2 limitations it should play fairly well.

So if you turn off NOs and do war declarations for it then you'll probably have an even better game.

@redrum tried it once with ai as axis already and didnt attack france.

ubernaut

@redrum another i've noticed in past ai at least on this map is that the ai doesn't seem to understand the effects of ports very well.

redrum

@ubernaut It didn't attack France at all? That would seem pretty strange. Does that happen frequently?

Yeah, I believe the AI will use the airfield and port move bonus but I don't think it actively tries to end in a sea zone with a port (I believe it does actively try to land where there are airfields).

ubernaut

@redrum well in the past at least it wasn't aware of my range and i only saw it not attack france once wiht the prerelease but i will try it again.

redrum

@ubernaut Ok, I believe it should be aware of your range and if not that's a pretty big issue for the map as it would make it very easy to pick off their fleets since they wouldn't see the threat.

ubernaut

@redrum i will check it for sure.

redrum

@ubernaut Are you the one that reported this error? https://github.com/triplea-game/triplea/issues/5929. If so can you describe when it occurred and are you able to reproduce it?

User Description
started game g40 2nd additiona with ai hard for axis

ubernaut

@redrum yeah that was the second time i tried the ai might have changed some of the game options but not 100% sure how i had them set i think i unchecked choose aa casualties, and maybe remove tech tokens (but not use tech :P)

Captain Crunch

@redrum you rock!

So, I test re-ran the same battle against the Allies AI and this time the Russia AI did attack on its 1st turn -.-

I'm glad the bugs were minor so I think I will now battle the Axis AI (1st match I will forfeit my 1st Russian attack for fun ... funny irony since the AI just did that vs me previous match hehehehe)

YES I thought the Russia AI not attacking anything on the 1st round was bizarre and so after I made my post about it I had a thought about it ... so I downloaded the latest AI upgrade prerelease 2.0.17997 because I was playing the 1.9.0.0.13066 stable release version of the game and so the game downloader asks you to update your game to 2.0.17997 and I clicked yes ... well I then ran the game BUT I DIDN'T REDOWNLOAD THE WWIIClassic MAP although it was still in the game folder and I could still play it but I just wondered if not redownloading the WWIIClassic map may have caused that weird glitch? Just my thought.

Ok, I really should re-battle the Allies AI (it's the toughest scenario to battle against the AI since the Axis AI is easier because its just 2 countries) but I will eventually try for a win vs the latest Axis AI and then post it.

redrum, thanks for understanding and mentioning my problem with the Combat Window ... it just needs like 2 or 3 more centimetres height or lower those Quick/Fast buttons below it or make it so we can remove those Quick/Fast buttons below the Combat Window.

I'll post my win vs the latest Axis AI asap

ubernaut

@redrum keep getting that error no matter which options i set

redrum

@ubernaut Yeah, that's a bad error. I'm assuming its happening during the AI's turn? Do you have a save game that can reproduce it?

ubernaut

@redrum it happens right away during German purchase phase so there's no auto-save yet.

redrum

@ubernaut Oh really? On just a brand new G40 game? Does it happen pretty much every time?

ubernaut

@redrum as far as i can tell yeah like 4/4 now

redrum

@ubernaut Alright. I'll take a look then today.

redrum

@ubernaut I was able to reproduce and fix the bug on G40 G1 related to the error "IllegalStateException - ConcurrentBattleCalculator.calculate: friendlyUnits should but does not contain all units from targetsToPickFrom". Here is the PR and once that is merged, you can download the new pre-release to avoid the error: https://github.com/triplea-game/triplea/pull/5933

Thanks again for testing and reporting the issue.

ubernaut

@redrum sure happy to check out the ai again after the update im not sure how to be notified tho so you might want to ping m.
