Thank you TDW, you are the man!

Is there a parameter for weather-dependant cannons accuracy that you know of? I wonder if this aspect was implemented by devs :hmmm:

and also, taking cue from this discussion, are AI visual sensors affected in any way by wind speed/waves height?

my opinion on this is i would rather they miss unrealistic when close so the mid range to distance accuracy is somewhat realistic in hit to miss ratio. by the time they get close you have already passed any realistic aspect of the game anyway since you would be dead after they get within a certain range.

I think a way to affect long range accuracy would be playing with AI Cannons Max error angle parameter, since at long distance a small increase of it would have a greater effect than at close range. :hmm2:

minimum elevation should be easy to fix: there's a parameter for each single gun in guns_radars_01.sim file. :yep:

I have had really good luck evading hits from armed merchants, in fact, never been hit by those. I never did stick around very long to find out though:O:.
Does the merchants accuracy differ from the warships? When I played a couple of the Historic missions recently and was fired on I think I was only hit once (and didn't even know it, I just got a "Damage repaired" message from the chief). Is this the only adjustment we can make ya think??:hmmm:

My impression is their accuracy is very similar. What warships have is more weapons and firerate, but I don't really see a difference in accuracy. Probably also warships can spot you much farther, not sure because I don't stick near them too much either!

But this is just an impression, we'd have to look at the files to know.

I was returning to Whilhelmshaven last night south of Portland, out from the French coast, and came upon a West bouund Hog Island Merchant. No torpedos so I had at it with the deck gun. We did a close quarter head on attack, with the merchant firing only from it's bow mounted gun. We were about 1500 meters apart thru all this. Had several hits that did little damage. You could hear them ping off the conn and deck. Boy did that get everyone's attention.

I managed to finally knock out the merchant's bow gun. Once it was out I pounded the daylights out of them and sank it. It took 34 rounds to do the job.... AP and HE. We used 12 HE and 22 AP, with only 2 AP rounds left out of all our deck gun ammo.

Yeah, next time I will get screenshots. Attacking shipping with the deck gun is a foolish way to get tonnage, especially with warships in the vicinity and in the Channel. I doubt I'll be trying this stunt after Dec of 41 with any warships around. We hear the Yanks will be tough buggers.

Another good question would be: is accuracy affected by AI crews ratings?

Yep, soon after the beginning of the conflict U-boat captains received the order not to engage enemy shipping with the deck gun, if other options were available. Eventually, during late war, its use became so obsolete that only few U-boat of the type IX were equipped with it.

I would have to say weather plays the biggest part in determining how effective approaching and/or engaging enemy ships while surfaced will be. For whatever reason, the last 2 weeks of my current patrol I have had either Medium or Light fog (it goes back and forth between the two) and while doing the mission to sink a Capitol Ship in Scapa Flow, I managed to slip into the bay through the south channel during Medium Fog conditions on a night with little to no moonlight while traveling "Decks Awash" past 3 different destroyers no more than 1500-2000 meters distance from my sub without being spotted.

After sinking the one Battleship sitting close to the harbor, I went to "Silent Running" back to the south opening of the bay where due to low batteries was forced to surface with a class B destroyer still between me and freedom. With the Medium fog I was able to close to within ~2500-3000 meters of the destroyer before visually sighting it, and I preemptively engaged the destroyer with AP rounds from the deck gun (I had no torps left). The destroyer only had a chance to get one round off, which flew a couple meters above the forward deck before she was finished off (it only took 3 AP rounds!?!?) I then went flank speed South-East of Scapa Flow for ~20 minutes, shut down engines, and settled on the ocean floor until nightfall again to make good my escape.

GT!! Do you go through the channel to get home to Wilhelmshaven????
If you do...wow. I've got to try it. I always thought it was suicide.

I know that in SH4 the DD's varied from ship to ship somehow (I've got to go back and review that, it's been awhile) So...I'm wondering if there's a chance that this is possible in SH5.:hmm2:
In SH4 I think part of the DD or enemy ship's rating was Elite down to Green or Novice. I know that there were a few DD's in SH4 that you didn't want to get caught by, just because of this Elite rating. So,,,they differed from ship to ship.
