Submarine's swing

[W_clear]

I think the reality of the submarine swing, it should be like this animated image
when i adjustment the wave of 15 meters wind speed.Not too big waves in the circumstances, the submarines have to make big ups and downs from top to bottom, and the spray splashing, and a splashing sound,It is very difficult. But I completed.:-?

Great work . Does this make small craft have damage from waves ?

No, it doesn't.

That looks nice !

When did you release it ?

Are you only working on the scene.dat with this? - you might want to take a look at the ROW roll pitch mod, where Dave edited the balast tanks of the submarines and the subs ballance to make it move more with the waves, but it seems you have it working ;)

I am sorry. I would like to release it, but I do not want to undermine the rule here, although I think that is not appropriate, because I didn't have to use others Files .:hmm:

It's a nice mod but historically, a sub in that kind of weather wouldn't be operating at the surface anyway. The pitching would have even the most seasoned veterans "gripping the rim" and hurling constantly. Not to mention the stresses imposed on the subs structure and the fact that it would be next to impossible to target anything.

Almost every account of heavy weather sub ops I've read had the sub going deep to quiet water and waiting it out. ;)

Hmmm but sometimes bad weather holds on until oxygene is over so what did the crew ?
Suizid by C02 or did they try to drive surfaced ?
:rotfl:

So that is historrically cause no sub in WW2 could dive for 1 week ore longer and every Sub including the snorkeld one must surface at this kind of weather when oxygene is empty and batterys are weak.

@ W_Clear

U can use other files if you ask for permission for using them.
After this you have to name the author in the credit-list.
Where is the problem ?

Suizid by C02 or did they try to drive surfaced ?Actually, they surfaced occasionally for radio traffic, check on the weather conditions or try to get a navigational fix. I don't recall a boat every staying down so long as to cause CO2 issues...

However, that being said, if surface conditions were still "mpossible" they simply went back down again...

WClear Im not acusing you of using others work, but wan't to help you, because I know your skills, if you have improved on the submarines movement to make it more realistic, you should release it.

[Will-Rommel]

Yeah i'm curious to give it a try and see how bad the sea can be!
Release it mate! :rock:

[swdw]

Posat this as a test mod for people to try. Others can look at the files to see if there are any problems.

For the wave height in the animation, the boat seems to be pitching up and down too much. People that haven't been on submarines often think they pitch and roll much more than they actually did.

About 2 minutes into this nice vid. ( 5 part series on the Silent Service )there is a nice view of a sub in fairly calm seas, the pitch seems to be very evident even with the sea in this state.

RDPYes, but look at the motion of the whole sub, it's not pivoting around it's center point like a see-saw. It's rising and falling on the swells, the apparent motion of the bow is augmented somewhat by both the swells, the up and down motion of the whole sub and some pitching...

W Clear's mod would be more realistic if it had some "dampening" to "smooth out" the violent pitching moment it currently has IMO.

[Vorkapitan]

W_Clear,

Are you going to release this mod for all of us to use? ;)

Ohh.. ive got to get all the bookmarks to this when i get home. :88)

pitch is less evident if you watch the start of part 2...

Hi RDP :D Is there a way I can copy these for my own personal use.

I want to watch them on big screen and surround sound. :yep:

[ReallyDedPoet]

@ Firewall: You have a PM.

Have a look at this video from Part 3 of that series, gives you a couple of different looks. Around 20 seconds in caught my eye. 5.00 in gives you a real nice full length pic of the sub, very nice view of the pitch.

One thing that is bang on though is SWDW's diverateRC2 mod, as the sub sits low in the water in all of these vids.

its also available on DVD, just do a search. Great find! Really good info! Its one thing to read about it but another to see the folks in the CT working.

This swinging of the boats is fantastic.

If you wanne have also nice swinging ships in a rough sea all ship sim-files have to be overworked in the following chapter with S3D:

- unit_ship
- obj_Hydro
- surfaced
- drag
LR = dont change this value
UD = set this value to 0.001 ( origin is mostly 0.3 )


For smaller Vessels like Destroyer or some Subchaser and Tugbots set the gc_height value 0.5 points smaller like the original setting.

For example the Auxsubchaser got an origin gc_height value from 3 so you have to set this to 2.5 !

After this is done to all vessels you will see very realistic swinging vessels in your stormy sea !

Here an small Video where you can see the result :

I just tried the above and it looks very nice Wclear ! :up:

Unfortunately we can't use this with the Submarine roll pitch mod, because the setting softens the oppresion on the submarine when it's swinging, this means if I use the above setting with the roll pitch mod and you get hit by a divebomb then the submarine will swing from side to side (allmost 180 degrees!), so I guess we have to choose between having the boats swing or rolling. To bad it would have been awesome if we could combine the 2 settings.

You are welcome to try, the setting that controls the submarine rolling is the GC height, if you increase it the submarine will start to roll more on the waves, Dave used a setting of around 3 to 3,5 never more than 3,5 ! because then it will flip upside down.

Allso the fr_ratio should be at 0,5 (the center of the sub)

He allso increased the flooding speed in the balast tanks, I think it's because then the water inside the submarine will help with the rolling, but Im not sure about it, here you should use a ManBT_flood_speed at around 29000 for smaller sub and not more than 35000 for larger subs.

[Sailor Steve]

I (http://I) have an old issue of Warship International magazine with an article titled "It's Rough Out There." The article describes what happens to a ship in different sea states, including details of all the different motions. Unfortunately the magazine is in storage with my other books, so while I can describe the various motions, their names won't necessarily be the correct ones.

1) Pitch: the motion WClear calls "swing". The bow and stern move up and down with the waves.

2) Yaw: the bow and stern swing from side to side.

3) Roll: the ship rolls around its centerline.

Those three are obvious; but not so obvious are the other three motions, which are taking place at the same time, and sometimes in the opposite directions from the first three:

4) Heave: the whole ship is moving up and down. Sometimes the bow is pitching down while the ship is moving upward.

5) Surge: the whole ship will suddenly move forward, or backward, a little faster than its actual speed.

6) ???? (I don't remember the name for this one): the whole ship will move sideways.

Now, since the ocean's currents are never constant, you will have the bow pitching down while the ship heaves upward and suddenly slows down, the bow swinging to the right while the ship is moving to the left and rolling to the left; and five seconds later the exact opposite is happening, or worse, a different combination.

Even in "calm" weather all this is happening in small amounts, so watch that video clip again with all this in mind, and you'll see it in action. Now, try to load a gun or torpedoes with that going on. It's why they call it "having your sea legs", and why old sailing-ship sailors walked funny when they were on dry land. And, as pointed out, why if the weather is rough enough even the oldest veterans can get seasick.

You can use it bothe but you have to change the RL drag settings of the boats back to stock values !

Unfortunally W_Clear changes this settings too.

4) Heave: the whole ship is moving up and down. Sometimes the bow is pitching down while the ship is moving upward.

Yes, and I believe the clip that was given as a an example of a sub "swinging" (pitching) was actually much more an example of a sub heaving up and down on a large swell (pitch did not appear to vary much more than 10 deg. from horizontal). Apparently the film was from relatively calm weather conditions but with large swell, which I don't think can be replicated in the game. If I'm not mistaken, ocean swell (wave height and length) is tied directly to local weather conditions, increasing as wind speed increases.

[The General]

It was very difficult. But I did it.:-?I don't doubt it W_Clear! If you've achieved what almost everybody else couldn't, I'm gonna go ahead and herald you a genius!

[Aur0ra145]

Ok guys, this roll, pitch and yaw stuff has made me seasick.

See, I'm working on a mod which will defy all realism and what not...

So I decided that having a Balao that could do barrel rolls would be awesome.


I played with some stuff, namely LR drag and engines RPMs with a bhp boost and now I feel ill.

I got the boat to going at a Flank x2 sort of speed while submerged and took a turn, and then the death spin began.


But as always, I won't be defeated (I was playing some quick mission.) And I attempted for 20 minutes to AUTO-target anything while my periscope was swinging across the surface for ~1s intervals. AND I don't have stabilized view.

I need dramamine.



:eek:

P.S. It is possible to surface keel up. I do not recomend this.

[misfitdreamer]

i really wish w_clear had released this.

[vickers03]

i really wish w_clear had released this.

it's included in the environment mod:yep:

[keltos01]

does it take into account the subs' size ? length/width/height ratio to compute the pitch ?
My IJN submarines are much larger than the german or american ones for that matter, would it show or is it a "fixed" pitch ?
