I was looking at the RAOBF and I think I need some help.

So far at x6 scope I am seeing the following.

Pic 2



So this looks like it works for scope x6.

Does anyone know how to work for scope x1.5?

I do not know anything about this specific edition of the Range and AOB finder (don't have SH5, so not familiar with this mod), but I do know how it works in general. (I used it from it's inception with SH3) I think you are looking at the wrong place for the optical length of the target (green arrow). It should be found on the inside scale of the middle (moveable) wheel. That will be aligned to the AOB as calculated by the device. In the second image you have the green arrow at 6.5 (650 meters range), instead of 7.5. So that one is certainly wrong. The scale that you have the green arrow pointed to is only to be used for range (number times 100 meters) values.

BTW did you first calculate the range, and then turn the wheel from the target (mast-) height value to the target length value? That is the proper way to set up the wheels for the AOB calculation!

I'm afraid that is not how the original RAOBF developed by OLC, Hitman and Joegrundman works. The scale pointed to by the yellow and green arrows in Trevally's images is only to be used for range. The inside scale of the moveable wheel is for observed height and observed (halve)length. Darkwraith's solution seems to work. But it can't, as the observed halve length is 10 marks, but (his) 10 is left of 90 degrees. And that is impossible in the formula. There is no angle that makes the sine of it become bigger than 1. (which is what the 12-o'clock position represents) What he does is cheating the numbers. Still, using 10 on the innerscale of the moveable wheel also doesn't work. Since it points to 15 degrees AOB. And that is clearly not the right angle based on the view. Somehow this yellow scale in the scope is wrong! The observed (halve) length should have a value of about 38 marks.

it's not based off of them that's probably why. It was developed using Karamazov (KiUB User Guide) as the source of information as to how it works.

karamazovnew just took the RAOBF from the U-jagd tools, simple as that.

Thanks Pisces

I will try some more tests with the information you have posted.

[TheDarkWraith]

Here is the document I based the RAOBF off of: http://rapidshare.com/files/44012975...ser_Guide_.doc

[Pisces]

From outside to inside scales:

most outer scale : real (mast)height for range, or real (ship)length for AOB

outer scale of moveable wheel: range only (number times 100 meters)

inside scale of moveable wheel: optical height or (halve?) length as observed in the scope.

most inner scale: AOB scale, 90 degrees is index to which observed height should be aligned for range measurement in 6x zoom.

I haven't played SH5 in about a year. Last I played it, TDW's UI was still on version 2.0 and there had been no word from him in so long it seemed like he'd quit.

I had a custom scope graticule that worked for the RAOBF with TDW's mod, it was ugly, but it functioned. But there seemed to be no cure for the problems with the recognition manual, etc.

My hard drive died and when I replaced it I didn't reinstall SH5 and that was that.

Anyway, last night I decided to check in and see what's been going on and--wow! TDW has released several improved versions of his UI, there is a new Campaign mod that looks like tremendous fun, the recognition manual has been corrected and calibrated graticules are available for use with the scope mods and the RAOBF--just fantastic. I can't wait to check out all of the new stuff.

A morning well spent! Again, I thought my calculations were screwed trying to to Trevally's RAOBF tutorial but, after installing Manos's godly scopes and reading through all the posts here I am getting faster and faster at the RAOBF range and AOB finding procedure.

Brilliant work to all concerned.

Have Tonilo Coyote's 'Real Dimensions' been incorporated in TDW UI or should I install that separately?


Cheers,

I'm glad you got it working - The RAOBF is a great tool when you get used to it and yes, it is very fast when used with confidence.

Making tutorials was great fun for me - I am surprised that more people have not made any.
Its very rewarding starting off with a blank notepad page and then just start typing. Bofore you know it - you have made a mod from nothing (not quite nothing as you need to use TDWs commands in his UI)

Making the tutorials felt more creative than making OHII as the tools (ME2) make campaign work easy

TDW has used the finding from Tonilo's work in his UI mod. It is also used for the new ships in OHII.

I think Reaper and Dr Jones would have used these as well - so no need to install

I have a few questions. Why do some tutorials tell you to count all the clicks along the ships length and other tell you to count half of them (the front half)?

When finding the ships speed by timing it while it passes in the scope, should the scope be at 1.5 x zoom or 6x?

Before I fire the torps, do I have to set the scope at 0?

Thanks,

Keith.

This is probably because some tutorials are based on the original mod they were based on, the OLC Gui for SH3. The creator OLC decided that it was easiest with his mod to read of halve of the marks, instead of all the marks. Iirc in the earlier versions of his mod he doubled the mastheight values in the recognition values to make the RAOBF wheel scales align better. In later versions he avoided that with requiring only halve of the marks to be counted.

But with so many different derivatives it's risky to rely on the precise procedures shown in these tutorials. Always go with the instructions that this mod comes with.

As the lock-on point for the periscope could potentially be offset from the model center (if some modder messed up his model offset) I would count all the horizontal marks, and divide by 2 if needed. Only considering the marks on the left or right side of the horizontal scale is risking false measurements leading to false AOB.

When finding the ships speed by timing it while it passes in the scope, should the scope be at 1.5 x zoom or 6x?

Doesn't matter, the line is dead-center of the view in both cases. And to null out your own speed effects, the periscope should be pointed 0 or 180 degrees, and the bow/stern turned just in front of the targets passage. Choose the zoomlevel that gives the best view on when the target bow and stern cross the line. So for distant targets this would usually be the high zoom level.

Are you sure, you have right solution for your target?
Don't use map, use external camera if you want to see your torpedo track.

Firing at this kind of angle is very disadvantageous, fire at 90.

Use rule of 1:1 - if you have target at 51 aob at bearing 221, it will have 90 aob exactly at 221+(90-51)=260, or was at 182 if it's at opposite direction.

And remember most important is to have absolutely prefect speed of target. You can have +- 5 degrees wrong aob if you have it's speed perfectly and you fire at 90 aob.

At 51 aob you need much more prefect solution
