if you have v31 installed remove it. That version (single file) really loosened up the AI's sensors. Set the difficulty settings to 100/100 and disable fatigue model. Now you need to adjust the DC settings to give them a larger damage radius and higher MinEF and MaxEF so that they do more damage in that larger damage radius. The DCs were adjusted so that the escorts could DC at shallow depths and not destroy themselves like they did in stock game.

If you want to adjust the depth which DC attacks can be made then you need to edit the \data\Scripts\AI\init.aix file. I have a setting in there that controls the minimum depth they can start DC attacks.

Thanks for replying so quickly. You must keep a keen eye on
subsim. Everytime ive asked something of you ive got a response within
the hour.
I had a look at the sim file but think ill leave it be. I was just suprised
at the AI behaviour. Usually if I tried to take on a Taskforce with so
many escorts I would have got hammered , Im not used to getting
away but Early War you should be able to get away without too much
trouble. Later years is a diferent story. Im keen to see how the AI
changes over time.

Thanks Again

BTW I realy enjoy the mods youve released , thanks for sharing with the
comunity.
Finally im going to try RealNav , wish me luck.

If you use realnav be sure to download Trevallys auto scripts .

How can i remove fatigue model plz ? And what is the minimum depth DC setting name into your .aix ?

Looked over my init.aix file and remembered some things:

FULL_THROTTLE_DISTANCE = 2000.0; this is the distance from contact that the warships will use full throttle until (you could set this distance as low as 500.0 with no problem)
PLASTER_DC_SETUP_RUN_SPEED = 0.5; this is the speed the warships will use when setting up for a DC run
PLASTER_DC_RUN_SPEED = 0.8; this is the speed the warships will use for their DC run (set to 1.0 for them to use full throttle)

for a sub contact the warships will use the PLASTER_DC_SETUP_RUN_SPEED inbetween FULL_THROTTLE_DISTANCE and PLASTER_DC_SETUP_DISTANCE. They will use PLASTER_DC_RUN_SPEED between PLASTER_DC_SETUP_DISTANCE and PLASTER_DC_RUN_DISTANCE

set all of these to 0 to remove fatigue model:
SHIPFATIGUESENSORREDUCTIONCRUISEMIN = 15; # min sensor reduction amount for each tier in cruise
SHIPFATIGUESENSORREDUCTIONCRUISEMAX = 30; # max sensor reduction amount for each tier in cruise
SHIPFATIGUESENSORREDUCTIONALERTMIN = 25; # min sensor reduction amount for each tier in alert
SHIPFATIGUESENSORREDUCTIONALERTMAX = 50; # max sensor reduction amount for each tier in alert
SHIPFATIGUESENSORREDUCTIONDAMAGEDMIN = 35; # min sensor reduction amount for each tier in damaged
SHIPFATIGUESENSORREDUCTIONDAMAGEDMAX = 70; # max sensor reduction amount for each tier in damaged
SHIPFATIGUESENSORREDUCTIONDAMAGEDALERTMIN = 45; # min sensor reduction amount for each tier in damaged
SHIPFATIGUESENSORREDUCTIONDAMAGEDALERTMAX = 90; # max sensor reduction amount for each tier in damaged

for ship DCs you have to look into the Ship-weapons.aix file:

precond
{
Ship:CanFireDCRacks() and Ship:GetContactDepth() <= -8 and Ship:GetCurrentSpeed() >= 2
}

if you make the -8 value smaller (less negative) then they will DC sooner. Notice that I also have a speed restriction on them. They have to be moving at 2 knots or more of speed.

A great thx TDW, i think i ll can do something ith this values...

Well, is a DD can use his canon to hit a low depth immerged sub and can he inflict somme damages ?? Is there any historical event like this ?

I have changed it to 500, but DD allways coming at 15knt... Any another ideas ?

what are you trying to accomplish? You want them at full throttle all the time? If so you need to change the DC_setup_speed and run speed and set them to 1.0

here my settings :

Have a question re. aircraft firepower:

In game aircrafts became more aggressive (in comparison with vanilla) , and that's great:yeah: But is it historically plausible that a pair of Hurricanes or Spits in 1939 could sank the U-boat without bombs only with the on-board weapon (machineguns)? Asking because in SHV with IRAI 0.0.31 5-6 battle turns of a fighters pair on sub reduce the hull-integrity value from 100 to 0 %:o
Almost sure You'll not find the historical cases of such event even because there were no such an idiots among U-boat captains that should wait for several airplane attacks without submerging as well as among fighter-pilots who dare to spent all munition on a U-boot and attack it without a couple of bombs under wings:06:

I either have them continue on following waypoints when they have no bombs or have them attack you with their guns if they have ammo. I think the latter is more realistic.

I didn't change the damage values of the shells for the guns. Maybe those need to be adjusted :hmmm:

Perhaps the damage value of the cannon rounds is too high.

I doubt that gunfire or light cannon shells can cause extensive damage to an u-boat or sunk it, only cause light damage or small leakings, it´s more realistic.

Except if the plane use heavy armour piercing shells , like 37 mm BK3,7 anti-tank cannon used by stuka plane or 6-pounder Class M" (57mm) cannon in the havilland mosquito.

" 900 lb (408 kg)of armour was added within the engine cowlings, around the nose and under the cockpit floor to protect the engines and crew from the heavily armed U-Boats, which were intended to be the primary target of the Mk XVIII. Two or four .303 (7.7 mm) Browning machine guns were retained in the nose and were used to "sight" the main weapon onto the target.

One question!

Would it be possible to get enemy ships and torpedo boats to shoot at your periscope when you are submerged?

It's a bit too easy to stay in periscope depth and linger around ships when they don't attack you. Even if they have guns and have clearly seen you, nothing, only if you surface they start firing. I got two PT boats circling around my periscope at 200 meters, but they just watched and waited. Has anyone witnessed other kind of behaviour?

This is propably part of the games mechanic but it would be great if they could be little more aggressive. Be more agressive!

Im sure they do attach your scope if it is raised Rongel.

I posted a pic of this in the Wolfpack thread:up:

Hmm... I'm not so sure about this, I tested this about pretty thoroughly. When I was surfaced at first, they started to shoot at me and continued a while even when I submerged.

But then I tested another method, I was submerged and then put periscope up, dd's spotted me and tried to ram me, they clearly saw me. But no one fired at my persicope which was up all the time. I had even two patrol boats circling around the periscope, but no shots were fired. At least 20 min passed, but nothing... But still interesting to hear other experiences! :DL.

Studying you pic now...
