[WIP] IRAI (Intelligent Random AI)

The game slows down during TC, which is an indicator that this has occured and he's become 'attached'. It takes a save/reload to shake him off.

I restarted the campaign yesterday, and this anomally occured during OHII's Scapa Flow mission. After sailing through Kiel Canal, passing closely by Hegoland, with TC engaged, I found that the game slowed (stuttering during only x1024 TC) for 100 miles into open water. I went to x1 TC, submerged to check sonar, and sure enough there he was; a friendly Escort, following me at roughly 10 - 20 km.

I don't expect you to spend any time specifically looking for this event, I just wanted to make you aware of it. It's kind of a big immersion killer. All the best.

This happened to me two times in a row. First was really irritating, I was being depth charged for a while but then seemed to lose the destroyer. But it was still circling behind me, doing really small circles and still steadily following me (i was going 1 knots, silent running). When I changed course, so did the destroyer. Wasn't sure if this was a bug because after several hours the destroyer left. But I could see that it was still following me, just keeping 7 kilometers distance. I saved the game and loaded it again to get rid of the bug, but it didn't go away!

The destroyer changed course and was now 12 kilometers from me. I continued my course back to base, and the destroyer was escorting me back to Germany! I could see it in the distance, not following behind but cruising right in front of me! So days passed and I finally started to approach coast. I sent a contact report from the destroyer, and soon the planes came. But the destroyer shot them down and suddenly "awoke" and was charging towards me. After few hours of depth charging, the destroyer finally gave up and left back to England....

Second case was today when a whole task force of destroyers started to follow me, keeping 20 kilometers distance. Saving and loading fixed this issue.

Maybe it was just bad luck, but it seemed that this behaviour is more common now, could some mod increase the possibility? It was a interesting find to see that the destroyer could "wake up" from the following mode, when planes attacked it, could this mechanic be used somehow to fix this issue? Like the General said, it is a big immersion killer.

Hi TheDarkWraith! Hi! With mod IRAI_0_0_37_ByTheDarkWraith I have big problems of the destroyers of the enemy in 1939 and in 1940! Although I know the weak anti-submarine defense in 39-40! Can You ask for advise me to put the weaker fashion IRAI?
1939 IRAI______ ?
1940 IRAI______ ?
1941 IRAI______ ?
1942 IRAI______ ?
1943-45 IRAI_0_0_37_ByTheDarkWraith
Thanks for the help!

I agree, this is a huge problem, because you can never know if a destroyer is bugged or not. I hope TDW will soon focus on this and help us out. I'm sure he can do it, he proved he can crack tougher nuts than this one!

Hi TDW!

I read somewhere on the Forum, that we don´t need anymore (can be disable) the MOD "TheDarkWraith_DC_Water_Disturbances_v2_0_SH5" when we use IRAI v0.0.37.

Is this correct?

Best regards,
Magic

Best regards,

Hello TDW, belong to a virtual flotilla (www.24Flotilla.com) we played much multiplayer, we like to attack convoys in droves,(wolfpack) we have observed that with the latest version of IRAIv0.0.37, escorts not very precise in their attacks when we discovered, launched their loads quite far from their position subtracting emotion submarines to attack, because we have never been sunk, and the attack on the convoy becomes a duck shooting.Do nothing but give circles around,in previous versions, if you have more precision.attacks were more complicated and fun.
Question: Could you put more precision attacks by bodyguards when they launch their depth charges? Can you tell us how it's done?
AI? Vary their behavior in multiplayer or does it just as campaigning?
Sorry my bad English I have to use a translator
Thank you very much.

What are your difficulty settings set at? Ensure they are all at stock (as designed) values. Are you also using my DC water disturbances mod? If so, disable it. If the AI is still too easy for you then you could adjust the settings in \data\Cfg\Sim.cfg (make the changes in yellow):

[Hydrophone]
Detection time=1.0 ;[s]
; lower values then 1 make it harder for AI to detect you
Sensitivity=1.0 ;(0..1)
Height factor=0 ;[m]
Waves factor=0.5 ;[>=0]
Speed factor=14 ;[kt]
;1 is on the deaf side
;0.10 is on the uber end
Noise factor=0.2 ;[>=0] was 1.3, decreased by 74.5%
Thermal Layer Signal Attenuation=1.0 ;[>0], 1 means no signal reduction, 3 equals signal reduction to 33% was 3.0, decreased by 55%
Min Signal Strength=0.1

[Sonar]
;how long you have to be in the AI's active sonar cone before he will start pinging.
Detection time=1.0 ;[s] was 5
; lower values than 1 make it harder for AI to detect you
Sensitivity=1.0 ;(0..1)
Waves factor=0.2 ;[>=0]
Speed factor=15 ;[kt]
;how much surface area you present to the AI for him to ping off of, before he gets a ping
;think of this variable as to how much "slop" you can have when pointing your bow or stern at an approaching AI to minimize your profile
Enemy surface factor=175 ;[m2] was 520, decreased by 35%
Lose time=20 ;[s]
Min Signal Strength=0.1
Thermal Layer Signal Attenuation=1.25 ;[>0], 1 means no signal reduction, 5 equals signal reduction to 20% was 5.0, decreased by 70%


Those changes will spice things up for sure

I removed the pinpoint accuracy the warships had in the latest version because people were complaining. You're now seeing that the AI really has no clue where you are unless you are actually spotted.
