Is it the only factor that make them giving up?
With IRAI, do the destroyers have limited depth charges?
(that brings me an other question to my mind, if no limited depth charges, the chalk board is useless...! Well not easy to count them anyway as the hydro guy don't announce them all)

v0.0.39 patch 1 is available at post #1 of this thread. This patch removes the ability of the ships to fire starshells and thus the severe game bug with it. Unzip to MODS folder. Enable after main mod and let it overwrite file.

I'll add my FX version of the starshells to ships sometime in the future (it's a butt load of work to do it :dead:). If you look closely at FX Update's starshells in game you'll see that I attached a smoke generator to them so that they give off smoke just as they would in real life from burning.

Thank you TheDarkWraith.

Your unzipper is creating the extra folder then. Uncheck the create folder option.

As far as the cannons shooting at your sub when submereged here is how the AI is coded for it:
- if sub is submerged is between 0 and 20 meters depth and:
- they can visually see you or can hear you on sonar then they will lob shells at you if you are <= 8000m.

The one that has the data folder in it :up:

Thank you very much for this patch TDW :up:
Even on pretty good computer, starshells were giving some freeze.

Wow, up to 8 Km!! :o...that's a lot! lol

I was talking about the passive hydrophones board the destroyers, I know that the U-boats sat high enough in the water that the waves on the sea nullify the effect of the passive hydrophones when the U-boat is on the surface.
Did you say the Undine class submarine has no passive hydrophone? then of does it track enemies while underwater?

Thank you man :up:

I just hope that one day you will manage to properly fix this feature, once and for all. I mean guns layed at maximum elevation and firing the starshells assigned to them in guns_radars_01.sim (if any), and returning to track enemy targets afterwards... :03:

I think you are referring to FX Update's starshells which, to my knowledge, are not removed by IRAI patch.

what do you suggest instead?

What you ask can be probably done by increasing AI hydrophone's MinElevation. :yep:
For most (or all) of the hydrophones it is set to 80 deg. Changing this setting to 85-90 deg should be enough to make hydrophones deaf against surfaced submarines. The only downside is that they probably wouldn't pick surface targets either. In order to make ships detectable on hydrophone by other ships, we should decrease the height of their hyd soundsource :hmm2:

Thanks for the patch#1, TDW :up:

TDW,

Just wanted to report my experience with the latest version of IRAI. I've been away from the game for some time. Came back, loaded up the updated versions of all the mods and I think IRAI is almost perfect. :up:

I got myself in some hot water in my last patrol. I was tracking an arctic convoy and got in too close. I was forced to fire my torps early when I DD detected my periscope (I was within their screen and pretty close to the DD). I dove (missed my target too :/\\!! ) and endured about 5 hours of depth charging and being hunted by about 7 destroyers. I took a few good shots from close DCs. Sustained damage but was able to continue on. I eventually lost them (but it wasn't easy) by going deep, 140m, and remaining still.

I think the balance of difficulty and playability has been found. Escorts are a threat but not impossible to escape from. Thanks for this mod.

Has anyone tested aircraft behaviour with the latest IRAI version enabled?

Were they dropping bombs, depth charges or torpedoes? :hmmm:

I've so far only tested it using the Trevally's patch for OHII and in this test mission the plane didn't dropped bombs.. :hmmm:

Try switching to the previous version then, and you will see what I mean :yep:

OK.. I will test it..

Nah, was thinking at first submerged...my bad :/\\!!.
Surfaced, it's ok :up:
