help with IRAI: The All-Knowing destroyer

[kapitan_zur_see]

Okay, just returned from being killed by an extraordinary stubborn, absolutely thorough and relentless destroyer... and not the first time I cross one... It got me totally fed-up

I'll ask you guys some help on how you escape destroyers

second mission with OHII during 1939. Crossed one destroyer in the baltic. I'v been taken out of compression time when it was 5400m away during a calm weather night or so. It went on to chase me, so I ordered a crash dive, then went on a speed of 2 kn. Early destroyer didn't even have an asdic, but a eventually successfully made a DC pass right on top of me. Damages were minor, I went on. The very most of the time, he was lurking around, doing circle kinda far from me, not being able to find me close enough to DC me.

The problem is, not matter what speed I tried, no matter how hard I knuckled from port to starboard, changing course often. He would ALWAYS be lurking around the same distance or so, sometimes closing, sometimes moving away, doing circle kinda far but ALWAYS keeping track enough to follow me. Schleichfart or what, he would sometimes do a DC pass even though he was out of DC.

Hours turned into a day and more (i'm not even sure) and yet... he was still there, keeping pretty much the same distance. No matter what I do, gradually increasing speed to try and put some distance whenever he was going farther, reducing next to 0, from bottom of the ocean to periscope depth... pointless!!

it seems like it was always COMPLETELY aware of my very exact position, this, even without an ASDIC!!! like it was all knowing but just making circles from some distance to try and makes it look like the A.I didn't artificially known.

Of course eventually, I ran out of batteries and had to surface and got killed...

Seems completely unrealistic that some early destroyer are able to track you down so accurately and thoroughly, not even abandoning combat when they're out of DC...

So my question, just HOW do you guys cope and tricks you out of destroyer using IRAI and mods??? because I'm totally lost... It's not the first time it happens for me even if I keep being at schleichfart

Many thanks!

Since oddly enough, CO2 doesn't rises though using tdw patch I can pretty much stay underwater with engines off for how long I want at 512x TC... Very fun to see it still at the very exact position doing its circles 4 days later rofl. Them he eventually disappeared! Is that how we're supposed to escape??? Not standing a chance maneuvering our U boat but just waiting for days??

weird... My CO2 levels work absolutely fine...
but... I haven't made to the second campaign.. or mission for that matter... eh...

In regards to the 'persistent frikkin destroyers' - I've heard 1kn works better.

When I had 5-6 DCs chaising me around in the original campaign (but w/ IRAI) after I sunk the carrier, took me about 18 hours to get away from them. Changing depths, using the disturbance in the water to do the full speed, etc...

So after installing the patch TDW, CO2 does not increase!

I noticed the same CO2 problem. I started noticing this problem when New UI for TDC is greater than versions 6.9. I have limited O2 set in options, too. I even unchecked O2, saved options, made manual edits in the GameplaySettings.cfg file etc. etc. to eliminate any false positives. I have patch 1.***74 for SH5.exe and have independent speed control CTDs.

I notice also that whenever I get too close of a ship (I believe new ships from ohii full), the game freezes every time. To hell with that game... Sigh

[Robin40]

'persistent frikkin destroyers' are very unrealisic

even 1knt doesn't work

and this is very unweird

it seems like it was always COMPLETELY aware of my very exact position, this, even without an ASDIC!!! like it was all knowing but just making circles from some distance to try and makes it look like the A.I didn't artificially known

sorry...I disabled IRAI

[bill clarke]

What is IRAI?

[Kalleblom]

I think the mod improved the Artificial Intelligence.

The R stands for random

This sounds a bit like the bug where the destroyer keeps following you no matter what you do. Usually it keeps over 10 km distance, but I have encountered also couple who circle above me when I'm submerged and they know my exact position. Even with 1 knots they follow me, and if I stop, they stop too. Days can pass, and it just circles there. Saving and loading the game makes the bug go away, but it is still very, very annoying.

Normally I think that IRAI destroyers behave really well, I can escape them if i'm careful, but it's not too easy.

@ Mikemike47

notice a wrong order

Repaired_Equipment_MOD_by_Xrundel_TheBeast_1.2
Equipment_Upgrades_Fix_v1_4_byTheBeast
Equipment_Upgrades_Fix_v1_4_Patch_1 & hotfix
Equip_Upgrades_fix_v1.4 dates by sober Patch V2

the red one, in my opinion, must be after the blue one and of course after all mods with the Ubootsensors.sim in it. there´s a modified Ubootsensors.sim file in TDW´s thread for the New UI, in the end of the first post above the yellow lines.

The downloadlink is dead, use this one:http://www.mediafire.com/?33188cldysg9sck

Also, TDW has instructions on how to "dumb" the DD's down a bit. I did it by going into the CFG files and looking for the lines TDW edited. He always leaves his mark on these lines along with the original setting so you can meet the setting "halfway".
But I remember and easier set of instructions for doing this. I'll try and find them if you don't want to edit the CFG files yourself. Go to \data\Scripts\AI\init.AIX. From this file, you should be able to adjust the parameters. This is from his documentation. I like having the DD's just ramped down a little because not all of the DD's are the same. I believe that some of them might have some sort of Elite value which IRAI would make nearly impossible to beat.
Good luck mate, hope this helps

I`m sure we are talking here about a well documented bug. "Super destroyers" are from time to time staying in your vicinity and you can do what you want - they will stalk you forever.
You can

a) reload the saved game
b) move to an island or to the coast and the destroyer will stupidly crash into the rocks and sink

It has nothing to do with the IRAI or other mods. Hope it is helpful.
