Didn't played this game for a while, and I can't remember what is the wide version :)
Now I wanna play it again and I wanna use my old save, if it works. But first I wanna make sure that the mods I used are still working :P
DarkRaven  [author] 30 Dec, 2024 @ 9:49am 
Yes, but I have not updated an error in the texture as of yet. The x10 should be x9.6. Out of curiosity, is there a reason you don't want to use the wide version?
DrunkenMclown 30 Dec, 2024 @ 4:38am 
Is this mod working with patch 23?
DarkRaven  [author] 3 Dec, 2024 @ 5:18pm 
Haven't been able to check for patch 23. Should still be working though.
ASkull 3 Dec, 2024 @ 4:23pm 
is this still compatible?
Thinkflight 28 Oct, 2024 @ 5:21pm 
@Trihne what Stadimeter mrad mod are you referencing?
Kerberos 29 Sep, 2024 @ 4:52am 
thx for this mod, i just try it maybe 2 min and i think it works :P But i dont have the the small linie for the viewing direction. this looks like vanilla. and can you pls add the milliradian for the UZO too?
Trihne 11 Sep, 2024 @ 1:53pm 
Welll I answered my own question... with the Stadimeter mrad mod, the value the stadimeter shows is exactly the same as the sights, 1 mrad is 1 mrad. not the case with hardscope or vanilla
Trihne 11 Sep, 2024 @ 12:04pm 
What is the difference between this mod and Hardscope? In hardscope, you divide the millradian by 16 to get degrees but with this you divide by 17.5, why? Are the sight's measurement more accurate... err no pun intended, with this mod?
DarkRaven  [author] 3 Sep, 2024 @ 7:30pm 
Vanilla periscope is still uncalibrated. 70 mrad on the stock scope is ~2.2 degrees on the stadimeter when it should be ~4 degrees.
DarkRaven  [author] 3 Sep, 2024 @ 4:28pm 
I'll check it out later. Hopefully you're correct.
Shinpuren 3 Sep, 2024 @ 3:04pm 
Is this mod still required? I think the base-game periscope is doing the same thing.
DarkRaven  [author] 21 Aug, 2024 @ 7:29pm 
@Ravenhold. Cool beans. The azimuth / bearing indicator is a separate mod.
Ravenhold IV 21 Aug, 2024 @ 5:58pm 
I cleared my cache and no change. HOWEVER, I have noticed that most of the scope is actually different from vanilla. It seems that the only part of my scope that hasn't changed is the azimuth indicator at the top. Everything else looks just like your mod.
DarkRaven  [author] 20 Aug, 2024 @ 4:52pm 
@Ravenhold Yes, as it has been for over 3 years. Only thing I can recommend is clearing your cache. Beyond that, I have no clue.
Ravenhold IV 20 Aug, 2024 @ 4:37pm 
Just launched the game. Mod is enabled in the launcher. My scopes are still vanilla. Is this actually save game compatible?
DarkRaven  [author] 20 Aug, 2024 @ 2:59pm 
@Ravenhold Dumb question, but did you enable the mod in the launcher? I just checked my local and the workshop version and they are functional.
Ravenhold IV 20 Aug, 2024 @ 5:57am 
It doesn't seem to work for me. I am subscribed to it, but I still have the vanilla sights in all three scopes. I only just subscribed so it is definitely updated.
Rudi Mentär 26 Jun, 2024 @ 3:41am 
Thanks for your reply :-)
DarkRaven  [author] 26 Jun, 2024 @ 1:39am 
The difference is that Realistic Periscope Sight is specifically for use alongside the Realistic periscope magnification mod (currently not functional for the unstable branch). RPM changes magnification levels and RPS is calibrated for that. This mod is for vanilla magnification.
Rudi Mentär 25 Jun, 2024 @ 11:03pm 
@DarkRaven
Thanks for your answer. I saw, you did a second mod called "Realistic Periscope Sight". Can you please tell me the differences to this one here?

I tested it and i cannot get any meaningful results with it.
I will post my results at "Realistic Periscope Sight". Thanks for your great work
DarkRaven  [author] 25 Jun, 2024 @ 7:42pm 
The magnification values I listed are relative to the 0.6x magnification, for easier calculations as the graticule is calibrated to that magnification. Thus 1.5 / 0.6 ~ 2.67 and 6 / 0.6 = 10.

You are measuring an Empire Explorer, as per the note on the bottom of the ID book, it's actual size varies +- 20% what is listed. I'm going to assume that's a major source of the error. With the values you gave, you should also see the target go about 5% slower when you use the chonometer to determine speed vs the map tools.

Additionally, and this is a minor nitpick, but given the values you gave, you should have gotten a result of 898 m. One thing I've been learning is that the third significant digit is vital for precision in these types of subsims.
Rudi Mentär 25 Jun, 2024 @ 1:49am 
Cannot get into it and get the correct range.. using the latest beta version und installed this mod..

You wrote: "x1/x2.67/x10" >> should be "x0.6/x1.5/x6" in game

1.) In game selected the x1.5 zoom ratio at the attack periscope
2.) the enemy ship has a mast height of 29.6 m
3.) optical mast height in periscope is 88 mrad
4.) I know, enemy ship is about 950m away (measured on map with tool)

RANGE (km) = Mast Height / OH * Magnification
RANGE (km) = 29.6 / 88 * 2.67 (x1.5 in game)
RANGE (km) ≈ 0.33 * 2.67
RANGE (km) ≈ 0.88 km
RANGE (m) ≈ 880 m
---------------------------------------
880m vs. 950m real range got from map? Please tell me what I am doing wrong..
DarkRaven  [author] 15 Jun, 2024 @ 9:23pm 
Sure thing, I just made my nigh-eternally work in progress guide public. Link here.
Darktemplar333 15 Jun, 2024 @ 7:05pm 
Can you tell us how to use the ratio AOB method? Or even link a guide to do it.
DarkRaven  [author] 13 Jun, 2024 @ 9:54pm 
More accurately, my dev version tried to be fancy by separating by game versions. That caused the issue. I have resolved the issue for future updates.
DarkRaven  [author] 13 Jun, 2024 @ 9:41pm 
It seems updating the mod's manifest did that. I've reverted to the previous version and the mod now works on my end. Apologies for the inconvenience.
DarkRaven  [author] 13 Jun, 2024 @ 8:32pm 
I'll look into it.
Sigfan86 12 Jun, 2024 @ 4:44pm 
Hi DarkRaven, i think there is something up with your mod, given on 2024.1. P11 it does not match your images shown above, and the graduation marks on the scope do not line up with its corresponding degree marks on the compass. Ive taken screen shots but am unable to post them on here. I can PM them to you if you like
DarkRaven  [author] 12 Jun, 2024 @ 1:55am 
I verified that this mod works as of 2024.1 P10.
DarkRaven  [author] 4 Jun, 2024 @ 2:23am 
I haven't tried it in the 2024 preview versions, but it does work as of version 2022.1 patch 22. I didn't see anything in the patch notes affecting this texture and I don't plan to try to fix anything until 2024 goes out of beta.
James 4 Jun, 2024 @ 1:28am 
Is this working on the latest version?
DarkRaven  [author] 9 Oct, 2023 @ 10:02pm 
I don't believe so, at least not with my abilities in any case.
Oni 9 Oct, 2023 @ 1:28pm 
Can colour fileres be added to the attact persicope?
DarkRaven  [author] 1 Apr, 2023 @ 9:35pm 
It has been for me, yes.
PzSniper 1 Apr, 2023 @ 4:39pm 
Is it compatible with the new version 2022.1 Patch 21?
DarkRaven  [author] 27 Oct, 2022 @ 3:15am 
No problem. I'm glad you like it!
PanzerFührer 27 Oct, 2022 @ 2:21am 
Thank you DarkRaven! Yesterday, when I wrote you that message, it was showing a black periscope optic, whereas the UZO worked fine. I have just redownloaded the mod and it works perfectly once again! Thank you once more for the great work!!
DarkRaven  [author] 26 Oct, 2022 @ 9:45pm 
Mod is updated and working as of 2022.1P9. Not tested for previous versions and I couldn't get multiple versions feature to work.
PanzerFührer 26 Oct, 2022 @ 2:14pm 
Hey DarkRaven!
First of all, let me thank you for the mod!
Can we hope to have it working again for this last update?
Thank you again!
AlexFoyle 21 Oct, 2022 @ 7:30am 
Unfortunately not working in 2022.1, same problem as HARDscope mod, everything is black (due to changes in scope & UZO I suppose)
Zcat 12 Jun, 2022 @ 1:39pm 
Heya DarkRaven!
Thanks for responding. I'm sorry you have lost interest in this one but thank you for letting me know where the guide is... ahhhh. OK... I'm not that smart. I can't figure out where id=2486594396 is located. Still searching for it. Can you give me a hint where to start looking?
Thanks!
DarkRaven  [author] 9 Jun, 2022 @ 11:05pm 
To be honest, I've lost a focused interest in subsims. Between that and the reload speed bug, which to my knowledge still exists, I'm not really motivated to work on content. However! While incomplete, I have published my guide, though it is unlisted. If you're interested in perusing regardless, look up id=2486594396. Feedback would be appreciated.
Zcat 9 Jun, 2022 @ 4:38pm 
How's your guide coming along. I really enjoy the periscope mod but I REALLY want to use it as intended. The description below has to be missing something or I am. I can't get it to work. Thanks for the mod. It's great.
mosene281 24 Jan, 2022 @ 11:56am 
Great mod, thx for all the work! I tried to test your formula for finding the AOB but it does not work. Is there any typo? Also i would love to read your guide about it.
DarkRaven  [author] 1 Jan, 2022 @ 11:45am 
I have a fairly comprehensive guide in limbo atm, but essentially:

Each ship has an Aspect Ratio (AR) defined in the recognition manual that is its length / mast height.
Each target has an optical height (OH), how many mrads high it is in the scope, and optical length (OL), how many degrees wide it is in the scope. You divide the OH by 17.45 to get the OH in degrees (you can also ballpark it with the stadimeter if you wish).

Assuming those readings were taken at the same magnification level, multiply AR by OH to get the Expected Optical Length (EOL), the optical length the target should be of it we at 90 degrees to you. Divide the OL by the EOL to get the target's aspect ratio. Then consult a sine table or take the inverse sine (asin) of the target's aspect ratio to get the AOB.
KevDawg 1 Jan, 2022 @ 12:58am 
Hey how do you get aspect ratio AOB like you mentioned? Can you provide an example? Thanks!
