Realistic periscope magnification

Description
Summary
Fix periscope magnification settings. Allows you to use an obvious equation to determine the distance to a target.
Divide the height of the ship by the centiradians, and multiply by 4 if the periscope is zoomed in.

The periscope has a milliradian reticle (like original German attack periscope type StaSR C/2), so to be precise, to calculate the distance in 1.5x mode , the following formula is used

Mast height in meters * 1000 / visual height in milliradians = distance in meters.

in 6x mode obtained value in meters must be multiplied by 4* .

*Because the magnification at 6x is greater than 1.5x by a factor of 4, and the periscope reticle (in real life the same) is normalized to 1.5x

Sounds brilliant Wintermu-ta. One of my favorite must haves in subsims, and did a mod of my own on the Camera.dat for SH4…

I am not sure, but isn't this already in the base game?

The base game has also milli radians and they work absolutely fine. I do not understand why this mod is needed.

Hi. I checked that the code I edited has not changed 100% in the new version, but the bundle with the new mod template should be rebuilt. But I couldn't do it right away (the game did not apply the patch - some errors) maybe I'll try to find a solution in the community. I'll try again in a few days. Sorry.

Hi Wintermute-ta
Can you shed a light on when this mod could be updated ? Sorry if i come off as a bit demanding, but it was just a magnificent add on :D

Any news regarding update ?
DarkRaven 15 Jul, 2024 @ 5:19pm 
You don't. You can figure out the mast height if you know the distance or the distance if you know the mast height. That's why ID book is there.

How can I measure mast height only use milliradian when I don't know its distance or/and AOB and the type of object?
I only want to get object's mast height and I know nothing about the target.

The mod does not work on the latest version (beta). I'll fix it later. Sorry

Mast height in meters * 1000 / visual height in milliradians = distance in meters.

Little bit confused... (using latest beta version of the game)

Got a enemy ship with a mast height of 29.6m and using the x1.5 zoom factor in attack periscope..
I know the ship is about 950m away from me (measured on the in game map).

Measured optical mast height:
----------------------------------------------
Vanilla game: 157 milliradians OH (measured @ x1.5 periscope zoom)
> 29.6m / 157 * 50 * 100 == 942m

HARDscope mod: 149 milliradians OH (measured @ x1.5 periscope zoom)
> 29.6m * 1000 / 149 == 199m ????

HARDscope mod + Realistic periscope magnification mod: 149 milliradians OH (measured @ x1.5 periscope zoom)
> 29.6m * 1000 / 149 == 199m ????



Why do I measure the optical height with "HARDscope mod" equal to "HARDscope mod + Realistic periscope magnification mod" - see no differances in game attack periscope

Where is my fault with calculating range?
