Slide rule: Modder's help needed for adding a neat tool to the nav map!
 

Erm... I'm a geek when it comes to calculating stuff in combat sims. I really appreciate the OLC GUI for adding a nomograph and the U-Jagd tools...

...but I want something a bit more flexible. I feel the urge for having a plain slide rule, basically a ruler with a logarithmic scale embracing a sliding tounge with exactly the same scales aligned. When you slide the tongue, you add up or subtract logarithms, and the scales' index numbers actually represent multiplications or divisions. Usually, a slide rule also sports a transparent sliding window with at least one line for just helping you out as a "numeric memory", and several other lines that represent basic unit conversions.

For anyone interested, please contact me, I will provide the graphics, if you provide me
_the config file entries and the how-to to manually add it to any mod or version of SH3_.

Feel free to add your thoughts here, I'm not going to take more credit than scanning an original slide rule (got a 1940's one) for the one who helps turning this into a mod.

First thoughts: I _guess_ this can only be achieved by adding 3 separate draggable items (ruler, tongue and window), I have not seen a draggable item with subsequent moving parts yet.

I thought a slide rule was added to U-Jagd in v1.3? :hmm:

You mean the circular "back" of the whiz-wheel? Now tell me one can use U-Jagd together with your GUI???

EDIT: I mean a linear one, a plain scientific slide-rule

There is no difference between a linear sliderule and a cricular sliderule except that one is linear and the other circular. Circular sliderules, however, are possible to make in SH3 while linear ones are more difficult...although you could maybe do it with a slider function I guess.

At present if you want to incorporate the sliderule into OLCGUI you'll have to do it yourself. If you are serious about it i can tell you how to do it.

Yes, I am serious about! I would love to see the B-Side of the Attack Disk in my OLC/GWX/RealNav environment!

EDIT: Just for a start... would it be possible to add a draggable item with two child items that would move with the main one and could be moved on their own (dependent on where you click)?
More basic: How can I add a draggable item?

How to add U-jagd sliderule to OLC GUI
 

There are two versions of the sliderule available.

The one that is bundled with U-jagd is modelled on the American SACF, which I find more versatile. For that one you'll need to download the entireU-jagd mod and find the relevant files yourself. Easier is to use the version of Hitman's sliderule to act as the B-side (in fact there is no real B-side, the sliderules were entirely separate) as the image files for that come as a separate download.

I'll assume you want to do the latter - it's much simpler.

Go to my filefront and download and extract the files called

U-jagd_alt_sliderule2.7z

Now you need to open it and copy the file called U-jagd.

Now go to the OLC mod folder. Make sure OLC GUI mod is uninstalled using JSGME.

Go to data/menu in the OLC mod and click paste.

You should now see a folder called U-jagd.

Now in the data/menu folder, you should see a cfg file called menu_1024_768.
Back it up as a safety measure. Then click on it to open it.

IF YOU HAVE MADE ANY OTHER ADJUSTMENTS TO OLCGUI, SUCH AS THE LARGE COMPASS ADD ON OR THE DRAGGABLE CHRONO, DO NOT PROCEED - TELL ME AND I"LL TELL YOU WHAT SHOULD BE DONE.

Also note that this version does not include the small KMcentreknob image. If you want it then you should get it from the main U-jagd download and paste it into the U-jagd folder you have just created.

Save and close the file

Now open the folder labelled cfg in the OLC mod file and backup and open the file named Dials.cfg.

At the top of the page alter the following line

DialsNo=74, change to, DialsNo=76

Now go to the end of this file and paste in the following section

That's it.

To activate it, you must FIRST click on the weapon officer and SECOND drag the mouse cursor to the bottom centre of the screen.

NOTE: I haven't tried this. Let me know how it goes

Good luck

joe

Yes of course it is. It's easy in fact.

To do it at the bottom of the parent object entry in the menu_1024_768 file you add the line

Draggable=Yes

Study the entries for the ubiquitous mod "Jonz draggable chrono" for exactly how it can be done.

OK Belatedly i realise you have already combined OLC with Real Nav.

You need to do the following correction to the menu_1024_768 entries.

Go to the bottom of the menu_1024_768 file. Click at the bottom of the file to move teh cursor there.

Go to Edit->find.

Select Up.
Type into the search field G3F.

Look at the line

[G3F I386] for example (this is what it should be in the unmodded OLC file)

Not what this number is exactly

Now for each of the entries I told you to add, you must make it such that the line

[G3F I...] follows the previous one.

So if in your search you find the number [G3F I389], then the first entry of the sliderule should be [G3F I390] and so on to the end.

Those are the only changes you should need to make

Joe

Thank you for this excellent hint. I will try that later, that's about what I was looking for!

Thank you for the instructions on how to add the circular slide rule from the U-Jagd tools.
I have to remind you though that your advice was not completely correct:

You told me to download the alternative slide rule files, but your instructions to edit menu...cfg used the filenames and positions of the original U-Jagd slide rule.
But when I follow your instructions in your post, and then paste the changes you mention in the readme file of the alternative sliderule, it works, just one change needs to be made:

Find this entry and change the highlighted line:
[G3F I...]
Name=sliderule
Type=1026;Menu group
ItemID=0x3F070010
ParentID=0x3F070000
Pos=106,630,600,600
Color=0xFFFFFFFFVertSlide=-720

to

Pos=-600,630,600,600

My assumption is that the ParentID of the circular slide rule somehow is the weapon commander's icon or his command icons, which are on the right hand side on the screen in OLC GUI, not on the left hand side in "stock" menus.
Making my addressed changes moves the slide rule to the horizontal center of the screen again as it should be.

Thank you for taking the time to work out a solution for me, I'm just about to enjoy having the slide rule :)

Thank you very much for the feedback and the correction, I'll edit the above post in case anyone else wants to try it.:D

Joe

Thank you! In the meantime I worked out a rudimentary linear slide rule... maybe I'm going to spice it up...

Hi lambda,

i´am very interested in your solution (especially in the "RelativeDrag=Yes"-part), even when it´s rudimentary, it would be a fine extension for my modding-tutorial .... and it would be helpfull for the next FF as well :up:

if you like to share, pls post or PM the code

I know this might be considered heretical, but why not just go ahead and use a real slide rule instead of a virtual one?

I carry a 6" Pickett N200ES Trig linear rule for when I need to be 'discrete' about playing (I use a laptop), otherwise I use Hitman's wheel (a physical version).

I picked the Pickett up on Ebay for a reasonable amount. I also have a plastic Sterling I got for $5 at an antique store.

Sometimes I even plot contacts on paper using a cheap ruler and protractor I bought.

Using a virtual slide rule is like kissing your sister: The motions might be the same, but it certainly doesn't feel the same.

Hi PB
You got some pix yet of your new circular slide rule?

Sorry! I just got busy with things, and forgot to post one.

Here is a picture of it:

http://img524.imageshack.us/img524/8...ture054qg3.jpg

I've used it a couple of times.

I ran out of transparencies, so I had to make the small wheel with the indicator arm out of cardstock.

I'm not entirely happy with it though, for a couple of reasons.

First, my printer seems to 'drag' when I feed it cardstock. Whenever I print out one of these things on cardstock and then cut them out, they aren't exactly round. It's more of an aesthetic problem then an accuracy one, but it's annoying nonetheless (although I must mention that it did cause an accuracy problem when I made a large circular slide rule).

Second, I don't think I centered the wheels as carefully as I normally do. I did it quickly in the evening one night, and I was hurrying.

It is accurate enough, though. I've used it to sink a couple of tramp steamers.

I'm thinking about getting a DVD drive for my home machine so I can put SHIV on it, and make a really good version of the US SACF/IS-WAS, which of course this wheel is based upon. I made a mini version of the Omnimeter side, which works quite well:
http://img178.imageshack.us/img178/5...ture055fa7.jpg

You can see that it is smaller than the German version, and in fact is less than 5 inches in diameter.

Excuse the crappy webcam pics, by the way. The good camera needs batteries.
