KSDII New Version 1.4.2

[Kapitän]

Hi All,


I thought it might be a good idea, to open a thread, in order to share some experiences with the new Patch 1.4.2 of KSDII.

Happy Hunting!

[Kapitän]

Hi All,

Decided to give the new version 1.4.2 of KSDII a try.

Installed the game as per directions.

Noticed that when creating a desktop shortcut, that the KSDII icon does not appear on the desktop but merely the sh4.exe icon.

Games starts up just fine. I like the little intro movie clip when selecting UAK for 1 Jan.1943 with IXD2 boat.

T-3 and T-1/FAT-1 available. Also, Bold-1 and Metox/FuMB-1. Twin-2cm/C30 available from the start.

FuMO-30 only available with Turm-2. Not sure when this will be (?)

When selecting "Leave from tender", the boat is actually positioned outside of Danzig harbour on the coast but not where it would be, when selecting "Leave from outside harbor". Also, the Anchor icon that shows the base location (Danzig), is located quite a bit in-land.
Seems like, all of these are not postioend correctly.

Experienced one random CTD just north of Hela ... when re-staring the game, didn't happen again (keeping fingers crossed).

Have been given different training orders and will report on those later.

When exiting the game, the game doesn't just shut down, but actually crashes and the message that "sh4 ran into a problem" appears.

Please feel free to comment ...

Hi, currently UAK flottilas are bugged.

Okay, clear. Just wanted to start the same on Version 1.4.1, to check if the same there ... so, no need anymore. Thanks for the Info.

What are some of the changes made in version 1.4.2?

[Niume]

Allied airbases slight rework
Fixed translation mistakes
Uboats now behave more realisticly in storms
US coast should now have less merchants.
The word "length" has been translated. Thanks to Mork_417!
The depth charge explosion does not cut off anymore. Thanks to Vickers03!
Campaign tweaks

Great! And the Campaign tweaks?

Slight tweaks to the fast merchants you should encounter more different classes of fast merchants, and I have slightly reduced the traffic around USA coast.

Sounds great! Thanks!

Anything about the general stabiliy of the game, in terms of CTDs?

[Kapitän]

Hi, currently UAK flottilas are bugged.

Is it theoretically possible to simulate leaving the UAK Flotilla at Danzig for the first war patrol, let's say to Bordeuax? Or would one experience some kind of UAK Flotilla related bugs along the way?

I can't tell you because I have never tried them. You can try it see if it works. :Kaleun_Wink:

Still trying to find the root cause of the CTD's

Okay, will do and let you know ... might be a while though ;)

[Kapitän]

Still trying to find the root cause of the CTD's

Okay .... unfortunately, I won't be able to help much with that other than merely reporting when they occur, which for me seems to be when,

a. approaching a convoy (the game attemps to load the convoy at about 25km distance) and

b. when under D/C attack (but not always and what seems to be at random times and/or when using the External View, F12).

[Kapitän]

I can't tell you because I have never tried them. You can try it see if it works. :Kaleun_Wink:
Just tried it: Well, it worked until it didn't ...

I started from UAK Danzig and left for Kiel, even entered Kiel and "Refitted" (Refueled). Everything went well, I left Kiel (for Kristiansand) and just outside of Kiel, already on the mine-free path, the game crashed.

Now, none of the game saves will load anymore.

So, it seems that this option is in fact not a workable champaign solution.

Hello) Perfectly executed modpack)

Hi there, I'm not sure if I'm doing this wrong or its a feature of KSD II which I'm not aware.

I am attempting to calculate range of a ship using the method from Solution_Solver_Angriffsscheibe_Wiz-Wheel_Attack_Disc_Handbook.pdf
page 13. The problem is when I tried using the periscope, I get a figure less than half of the actual range calculated by the auto TDC. what am I doing wrong?

1. Once you have visually identified the class of ship using your Ship Recognition Manual (Schiffserkennungshandbuch), you know the mast height of the <ship> is X meters.
2. Using your optics, measure the angle from the waterline to the top of the mast (see Appendix A). Angle θ is Y degrees.
2. From the chart above, you find that the tangent of Y degrees is approximately Z.
3. Divide X meters by Z. The target range is approximately <range> meters.

[Niume]

Are you using in game RAOBF disc?

[bratwurstdimsum]

Hi there, are you referring to this? If so I am not sure how to use it. I am only familiar with the other Angriffsscheibe (brown / yellow) disc.

Also if you are referring to the Help F1 perisopes guides, I do not really understand that either. sorry.

Unless, I'm looking at the wrong thing, the distance setting on the knob circled in red is 2750m (not 1023m), correct?

[bratwurstdimsum]

Hi yes you are correct, let me explain. I am using the TDC in this example to check my calculations so it’s not in manual mode. The method I’ve described gives me 1023m but the ships distance according to the TDC is 2750m. So my question is does anyone know how to use this periscope to calculate the distance from just the pips on the y axis?

Okay, understood. Sorry, I'm afraid, I'm not able to help with this one, as I don't use any of these tools myself ... seems way too tedious to me.

I merely use the namograph in the map view (F5) for speed calculation and for distance measuring the ruler, also, on the map view, that's it ... I figure, I let my Quartermaster do some of the work as well during an attack ;-)

For speed, I usually add another 1-2 knots ... the entire process is a mixture of some limited raw data, experience and pure guestimate ... seems to work okay as well :-)

[ElCid97]

Try using the top of the stack for the red line. It seems the stack is the highest point, which I believe is what they use in this example.

Otherwise, take the mast height and divide by the ticks/mils and then take the inverse tangent (arctan) and multiply by 100. Should be close enough. Arctan is also written as "tan-1" on some calculators.

Ex:

22.5/50=0.45

0.45 arctan=24.2277 ...
24.2277*100=2422.77 => round to about 2,400m for targeting purposes using the height you provided here with the masts and not the stack. The number I got using about 60 on the mils was closer to 2,000m which is still off from what they're saying here.

Please verify for me that this works in general (in the map, for example) since I'm just going off the cuff here based on other angle stuff I've been studying.

Also, I noticed the info is for SH3. This is for KSD2 which is SH4, correct? Is there a difference? What magnification are you using (not what you think you're using, but what's in the mod).

Hope this helps.

Hi ElCid and Kapitan,
Thank you for the info I’ll give it a go later today. Yes this info was for SH3 and so I was hoping someone had worked out how to do it given KSD II is still relatively new. I have determined yesterday that range is not essential to get a firing solution but it was just of those things that nagged me. Cheers Jeff

[ElCid97]

Okay, here's what I've been able to figure out just based on math. Not sure if there's something out there that can verify this is how they did it, but it seems to work on paper.

((Mast Height (m) / mils observed) x (Magnification Setting) * 1,000) = Range in meters (approximate)

In other words, take the 22.5 and divide by the 50 mils observed. The answer is 0.45. You then take that and multiply it by the magnification factor. I used 6x in this case. The answer should be 2.7. If you multiply by 1,000 you get 2,700 meters -- which is what I'm seeing (give or take) on the TDC.

I tried other numbers and they seem to make sense from a trig point of view.

As an example, if you take 22.5 and divide by 100 mils you get 0.225. You multiply by 6x and you get 1.35. Multiply by 1,000 and it's 1,350. That would be half the observed distance, which would make sense.

Let me know if you guys are able to test out the formula. It would make sense since it let's you figure out a rough distance without the need for trig. On a slide ruler (straight or circular) it would just be a matter of putting numbers across from each other and interpreting. An answer of 2.65 can be quickly interpreted as 2,650 meters.

Hope this helps! :Kaleun_Salute:

Hey Elcid thank so much!
I ran your the Arctan, and Magnification x 6 methods and recorded the results in the link below.

I found your first Arctan ranging method did not work for me and your Mag x 6 fell just short so I changed it to x7 instead and that worked great out to ranges up to 3,000m after that there is a degree of error that gets larger, the further away but that is not important anyhow as you would not be firing torpedoes at that range!

((Mast Height (m) / mils observed) x 7 (Mag) * 1,000) = Range (m) approximate)

[ElCid97]

Glad I could help! We could use this over with the WW I Kaiser mod since it means you're using simple math for targeting.

I've found a way to verify zoom levels. You have to check a "camera.dat" file for optics in the UZO as well as the two periscopes. I believe they are 7x for the UZO and 1.5x/6x for the two scopes, but I have to download something called S3D to read the thing, though. Need to find it here somewhere.

If it's 6x for the scopes, then I would use a factor of 6 for them and not 7 -- even if the answer is a little off. Remember, the max range of a WW I torpedo was about 1500 meters at most (until the end of the war, anyway). These methods were probably taken from the WW I experience, so it wouldn't be surprising that the acuracy drops at longer ranges.

I'll check the file unless someone who knows how to use the S3D beats me to it.

If verified 6x and 1.5x, then the formula can be updated:

For 1.5x
======

((Height (m) / mils observed) * 1500) = Estimated Range (m)

For 6x:
=====

((Height (m) / mils observed) * 6000) = Estimated Range (m)

For 7x (UZO only):
==============

((Height (m) / mils observed) * 7000) = Estimated Range (m)

For scopes with "5" and "10" instead of the 50/100 marks, just adjust the last value to move the decimal point as needed.

Glad this helped!

Got the S3D thing to work last night.

Checked the "cameras.dat" file that came with KSD2 and can confirm that the UZO is at 7x and the two periscopes are at 6x in the file.

The binoculars are set to 10.7x for the zoom.

For now multiply the UZO readings by 1500 (with the 50/100 graduations of the mils) and the scopes by 6000 and you should be fine.

I'm not sure what the newer SH3 releases use, but I'm inclined to guess they should be the same (1.5x and 6x). You would have to check with OneAlex and the folks at LSH3.

The main difference I've seen in videos with regards to those mods for SH3 is that the mils are 5 and 10 instead of 50 and 100 like with KSD2. If the mils are 5/10 on the scope, just multiply by 150 and 600 instead of 1500 and 6000 to get the estimated range in meters.

Hope I've been able to help!

the reticle and RAOBF calculation don't match, as well as the zoomfactor. I 've done a personal interface in Dark Waters, I'd do another mod for KSDII later if anyone need. Actually the Peri sight can also cal AOB directly
