[WIP] IRAI (Intelligent Random AI)

PL_Andrev · 10-28-10, 01:05 PM

Played historical mission "Fate of U-110" with:
IRAI.0.28 + FX.0.5 + Env.4.3 + 100% real

Used tactic:
Flank speed + obs periscope at surface all time

The escort ships are not aggressive. Both of them completely do not attack me (especially corvette). One DD "try" to attack but does not try to ramming me (periscope at surface all time) or swim over my position.
DD swims "near me" only / close to me and depth charges give me any damages. Strange thing - DD does not shoot guns to me (to my periscope).

it's quite possible that we need to tweak the new values included with v0.0.28. Try adjusting these values in \data\Scripts\AI\init.aix:

ShipFatigueSensorReductionCruiseMin = 0.015; # min sensor reduction amount for each tier in cruise
ShipFatigueSensorReductionCruiseMax = 0.03; # max sensor reduction amount for each tier in cruise
ShipFatigueSensorReductionAlertMin = 0.025; # min sensor reduction amount for each tier in alert
ShipFatigueSensorReductionAlertMax = 0.05; # max sensor reduction amount for each tier in alert
ShipFatigueSensorReductionDamagedMin = 0.035; # min sensor reduction amount for each tier in damaged
ShipFatigueSensorReductionDamagedMax = 0.07; # max sensor reduction amount for each tier in damaged
ShipFatigueSensorReductionDamagedAlertMin = 0.045; # min sensor reduction amount for each tier in damaged
ShipFatigueSensorReductionDamagedAlertMax = 0.09; # max sensor reduction amount for each tier in damaged

every time the ship enters into a new fatigue level a random value between xMin and xMax above is subtracted from their sensor effectiveness. Try adjusting the min and max values to smaller values. Once the 4th tier of fatigue is completed the sensor effectiveness is set back to it's full value (new watch crew) until fatigue sets in again.

rethinking this here: as a submerged sub with periscope up you are classified as an unknown contact to the AI. Now a surface contact (like a ship) can be classified as Unknown by the AI also if it hasn't visually contacted it. So, to be safe, what I did was have the AI go to a position some random distance away from the contact and basically follow it. If they lose contact with you then they will spiral search for you.

Now why they aren't firing guns at your periscope sounds like a game bug. I don't inhibit cannon firing at anytime. The AI is always allowed to fire guns whenever they want.

So this sounds like to me that the game classified your sub as an unknown but it knows you are submerged and thus has inhibited the AI from firing guns at you. It wants the AI to DC you instead.......

I'll make a test version for you here soon to test something for me

One Tribal did fire on my periscope. 2 DDs were going around me and even get very close to me (periscope view was IN the 3d object) but no ramming damage. Later one of the DDs saw me near the end of his vision range (good weather) and I went for 1 on 1 chicken game, with guns. he lost but my hull went down to 59%. But still I can disappear at 46 meters - first patrol in Mad Sea.

To replace my test: run "Fate of U-110" mission, full ahead with periscope into left DD. It looks like DD avoids my position / my periscope.
Maybe that is OK, but DD should use side's DC putters or torpedoes...

v0.0.29 released. See post #1 for details

PL_Andrev · 10-29-10, 05:17 AM

Tested mission:
Historical mission / The fate of U-110

Installed mods:
IRAI.0.29 (complete) + FX_Update.0.5 + Environmental.4.301

All images are captured with AI sub: Lemp's U-110:

1. Lemp is run with full speed. DDs are detect him (DD changes course) but no update course with current Lemp's position.
1a. Lemp have almost perfect position to shoot. He doesn't shot.

2. Lemp is surfacing (why?), but after first hits he goes into deep. DD should know his real position and probably course...

3. But they looking for him at his first position when he was detected previously!

It looks that enemy sub is detected at point XY, and all escort ships are looking for him near XY point, with ignoring / no reaction with other (or this same) contact.

I also notice if you surface the DDs won't shoot at you unless you shoot first.

PL_Andrev · 10-29-10, 07:25 AM

Checked the escort ships in this mission: all competent with defensive tactics.

With IRAI.0.29 the attacking DD (A&B) does not attack my sub by "ramming my periscope and dropping DC into this position".
When he was on my back, he still avoids my position (keep parallel course to me) and drops DC. Very stupid.

About shooting: A&B class in this mission is very passive with shooting to my ships. Only Flower class corvette is active with good degree.

In this mission are two german subs and three escort ships.
When "attacking" DD is sunk, other (second DD) does not go to my position to attack me.
