[WIP] IRAI (Intelligent Random AI)

Thx stoianm and Trevally.

Hi TheDarkWraith!
Once through the free camera there was a strange situation with IRAI: when a plane plunged into the boat immediately, but the plane continued to see the boat and fired its machine guns, although the boat has long been located at a depth of 90 m.

Yes this is a problem with the plane AI. There is only one function available for whether the plane has a contact or not. This function says yes or no as to whether it does. I cannot determine the depth of the contact (like you can with ships) and thus if the plane has a contact it will attack it (if it has bombs or torpedoes available). Doesn't matter if the contact is at 3000m or -300m the plane will still try to attack it This can only be fixed by the devs via a patch.

I'm running this with TDW's UI/TDC mod and the "U-boat Historical Specs" mod.

My order is this:

1 NewUIs_TDC_6_3_7_TDW
2 U-boat Historical Specifications
3 IRAI_0_0_30_TDW

I noticed that IRAI overwrites some files in the historical specs mod. Is this going to be a problem?

I had a strange problem with this mod (it was in MO) but i guess its the same AI mod. sometimes the escorts ignore me. One time i made a submerged attack and i struck a couple of targets. The escorts where in the back of the convoy and just kept sailing at slow speed with no interest in tracking me down even though it was good weather. The other situation was when i was attacking on the surface when fog. I could barely see the ship but attacked a few. I killed 5 ships and there was 1 escort . But the escort just kept sailing in the front of the convoy and also showed no interest in finding out what was happening behing him.

IRAI assigns escorts duties randomly. It's quite possible that these escorts in the back were assigned to guard convoy or protect convoy and as such they have to stay with the convoy until you come within a certain range of it.

If an escort is leading a convoy and it's the only escort then yes it will just keep leading the convoy. Beware airplanes though as it will be radioing for help via air cover and from other warships in the area.

I have an even worse situation witch is unacceptable for the AI destoyers. I attacked a convoy at evening with clear view. Attacked 4 ships. Still the escorts where doing nothing to help and didnt even have search lights on. They just kept sitting there while the merchents where looking for me with searchlights. As a test i desided to surface within the convoy and soon enough the merchants opent fire but the escorts just sat there with there lights of watching the fireworks at some 1000 meters. I,m talking a well defended convoy here , 1 one the front 2 at the sides.

Talking about planes... I posted few screens about an encounter with a bomber where after he depleted his ammo he still kept flying around me. I managed to damage all her engines, but I also depleted my ammo. So I reported the contact and about half an hour later a german destroyer joined the show. But soon as the 2 AI made contact, the bomber left. For role playing this was great... the bomber crew got scared and they left the area, but in reality.. dunno what trigged the abandon_attack.script.

Anyway, the AI vs AI battles are a real joy, best one is around Malta where the Luftwaffe constantly raid Valleta and thats a hell of a show, so if any of you is doing mare nostrum, dont forget to pay a visit in the area.

That sounds like stock AI behavior. Which version of IRAI are you using? As a test to see that IRAI is installed correctly when you have it enabled go to \data\scripts\AI and open up init.aix with notepad. If you see some settings that mention difficulty settings then it's installed correctly.

I am now in the campaign "Paukenschlag" and I am cruising around in front of the east coast of the states... Yesterday I was kind of bored and thought it might be a challenge to attack one of the destroyers patrolling around.

Well, I did... and it was really stupid behaviour. There were actually three destroyers in visible range (day, clear sky), I could see the other destroyers very clear and close (maybe a few kilometers away). I attacked the closest one and destroyed it very easy... The others took no visible action. It was easy as eating a donut to sink them all one by one...

I have the latest version of IRAI installed...

That just doesn't sound right. With the mod enabled check the following file \data\scripts\AI\init.aix and see if it contains anything dealing with difficulty settings. You'd find it at the beginning of the file if so. You can open that file with notepad. If it doesn't then IRAI isn't installed correctly.

i did the same but the DDs were like not moving... so Meldric you are sure that the DDs were in patrol and they were not like ancored?

yes good point stoianm! If the ships are anchored then they will always stay anchored and never engage. This is a game problem and not one that I created.
IRAI treats anchored ships as anchored ships. i.e. very little watch crew and support crew onboard and thus their detection ability is very limited on all sensors.
