Hello TDW,

this was in no way meant to criticize the mod, indeed the uncertainty now given to the player is top notch, even if it's too hard yet, in '39.
Are different sensors/detection systems with developing capabilities modeled, in vanilla SH5 - and in your mod ?

Apart from the time the current situation is based on, like "Happy times", or not-so-happy-times late 1944 which is a diffrent problem, detection and sensor-wise :

Problem is like with sea state, weather, torpedoed ships the sim does not save a lot of other conditions and settings, so when you come back loading a saved game you may be in a raging storm, while having saved in perfectly calm seas.

So:

1. Could it be that the destroyer AI simply does not know which sea state it is in as well - i mean you saved in calm weather and reload into a storm - but the destroyers are still in their saved "calm seas state" mode, and can thus see you while you don't ?

2. Do the destroyers generally see worse in bad weather/storm/fog/night, or does it not influence the AI - or asked the other way round - is any detection dependent on different weather conditions ?

3. Would it be possible to disable radar in very early conditions on say 3 of 4 escorts

4. Is the radar blindness when closer than 1000 meters modelled in vanilla, or mod ?


Anyway i lke this very much !

Thanks and greeting,
Catfish

(taken from IRAI v0.29):

[Visual]
Detection time=2.0 ;[s] min detection time.
Sensitivity=1.0 ;(0..1) min detection threshold double detection time.
Fog factor=0.85 ;[>=0]
Light factor=1.25 ;[>=0]
Waves factor=1.0 ;[>=0]
Enemy surface factor=50.0 ;[m2]
Enemy speed factor=8 ;[kt]
Min Signal Strength=0.1
Night Sensitivity Factor=0.3
Thermal Layer Signal Attenuation=0

This is all the AI gets to work with. See how limited it is? There's not much we can do to affect it's behavior weather wise, sea state wise, etc. I have the waves factor, fog factor, and light factors set very high to 'dumb down' the AI as much as possible yet still give a challenge.

If I could clone GR2 files and change the IDs (cause a clone needs new unique IDs) then via the ship's sns and eqp files we could make the AI change over time (years) thus modelling correctly the progress of allied radar/sonar/hydrophone. But until I can do that we are stuck with what we have.

Hi TDW,

this is indeed limited :-? - works surprisingly well with this few..

But it at least seams as if - even if the sea state/fog/night etc. changed drastically afte ra reload, the AI will take it into account - so my one theory is false, sea state will be detected with changing conditions.

edit: you posted before me, ok - well enough compared to Vanilla SH5 !

Thanks, something to think about ..

What i love about IRAI is now the ships have a fatigue roster . I play with 0.925 difficulty and now i have no clue whats going on detection wise . I might be alright so i go to peri depth and a ship might be sitting waiting and listening , then i spot another destroyer full speed for me . I evade for hours then all seems ok . I start heading away then some destroyer detects me . Holy mother of gawd .

I died 12 times in one mission. This is a record, for me.
The record in this case means that i played it again and again 12 times, to get away with all kinds of tricks, but to no avail. I finally accepted my fate lol :D
(b.t.w. why are convoys called task forces ? Ah i see, 12 merchants and 8 destroyers IS probably a task force :haha: )

And when i reloaded at an earlier time to evade said task force i changed my area of operation further to the west and guess what: 10 merchants without escort ! Could it be they did that right ? Was i too close to he britsh coast ? :o Will test this again ..

Do you play difficulty on 1.0 ?

Hello Sober,
yes, was all 1.0 but i will tone this down a bit in the next mission.

Just wonder if i should set visibility also to something like 9,5.
Not sure whether showing your bow or stern silhouette will have an impact on visibility at daylight, or night ?
I heard that there is a difference in detection when it comes to active ASDIC, whether you are running vertically or broadside to the ASDIC source ..

Greetings,

How much of your sub you make visible plays a big part in detection for visual, hydrophone, radar, and sonar.

Hello,
angle/size of silhouette plays a part for visible detection, that is good to know :up:

Thanks and greetings,

"A further factor was to select the right torpedo for the job, which became increasingly complicated as the war progressed. Thus, in the early days of the war each U-Boat´s load of torpedoes was a simple matter, consisting of either G7a or G7b, but in May 1943 BdU laid down that the load for a Type VIIC would be:

- Forward: four TI FaT I (G7a) plus six T III (G7e);
- Aft: two T III FaT II (G7e)

By April the following year this had changed to:

- Forward: three TV (G7es) (Zaunkonig) plus either five LuT or two FaT I plus three FaT II;
- Aft: two TV (G7es) (Zaunkonig) "
