[REQ] Rolling/pitching enhancement

[Dreamer]

Hi gang,

As best I recall there were tweaks done to SHIII that made the sub roll/pitch more in rough seas and I'd love to see the same thing for SHIV. It's nice that my sub is so stable for attack purposes but it leaves a bit to be desired when 95% of the boat is out of the water as the valley of a large wave passes.

Thanks in advance,

Martin

I agree Dreamer, Boat plows along like its on an underwater rail.

[Blood_splat]

Yeah I love what GWX did. I wish we had that in SH4 along with the no humming bird effect.

[Flybywire]

Yes, the boats loook just terrible bobbing around like a cork in a storm.

Easy mod, actually.This is how you to do it. First, you need the Mini Tweaker program. Also, be sure to download my sub.sim Tweak Files.

If you don't have SH3 intalled, you need to create empty folder directories like this:

C:\Program Files\Ubisoft\SilentHunterIII\data\Submarine\

Now, copy all of you submarine files from SH4 into this new, empty SH3 submarine directory.

Next, open the Mini Tweaker program and look for the submarine .sim files in each sub folder located in your SH3 directory.

Minelevation and Maxelevation settings adjust how many degrees the bow and stern move up and down. Also, gc_height adjusts the center of gravity... meaning how much the sub will rock back and forth in the waves.

Important- when modding, never leave backup files in your SH4 Library directories. If you do, the new, modded files will not be recognized by the game and the changes will not show. You must move any backup files out of the SH4 Library folder. Backups in the SH3 Library folder doesn't matter.

Good luck. :arrgh!:

Any way for someone to wrap such a thing in a JSGME package for enjoyment by the masses? Wouldn't have a clue on adjusting figures. ;)

[Burnspot]

I think I'm going to give this a whack (I'm not mod maker, lol) because I'm tired of "flying" my Gato in heavy seas. Anyone know what sort of values should be used for those variables NVDrifter mentioned? I haven't a clue. ;)

[nimitstexan]

My guess would be to strat with whatever was used on GWX, then tweak from there . . .?

[Burnspot]

Resurrecting this request. My pathetic attempt at modding this myself didn't work out, lol. Sitting in the middle of another typhoon, my Balao class floating in the air while the rollers push by, wishing I could figure this one out.

[Pete379]

Hi I tried to do this myself to and it seems to work better. The Mass = line in all the Sub .Sim files is 0 so I tried putting Mass = 1798 and also the line gc_height = 2.4 for the Balao and it seems to work better. In the Sim Cfg I put Waves Amplitude=0.85 and Waves Attenutation= 0.05 i'm still experimenting with these values though. Also the ranges or milesSurfaced setting under Diesel Propulsion in the Sim files are a little inaccurate I think so I put the numbers from www.fleetsubmarine.com (http://www.fleetsubmarine.com) in to. Hope this helps. ;)

Watch out when you adjust wave height. If I remember correctly, merchants and escorts were sinking when in storms playing SH3. I believe the modders worked around this though. The Dev's probably coded this due to the fact that the watch crewmembers go back down into the boat when you hit a specific depth. A classic example of having one but not the other! Rolling seas, that is...

Hello All!

I tried editing the files as Pete379 suggests, I am currently on a mission in a Porpoise class.

I set the mass at 1100, and the other settings per Pete379's recommendation. I have found that the boat has a nice roll to it, however, I discovered a couple other things in the process.

Making the boat roll and pitch will cause you to excersize better seamanship! In order to maintain way without wasting fuel, you will find it better to cross the waves at an angle. Ramming waves head on will cost you in fuel use, and your crew will not sleep as well, and thier performance will be affected!

Once I made this discovery, by heading at a shallow angle while surfaced, my crew was better rested, and I used less fuel. I used my submerged leg to head back toward my base course.

Try the changes and see what you think. Milage may vary...

Wish this could apply to the deck gun...

[Kataki]

Hey pete/CaptBC, would you mind hosting your changes online when you are done tweaking the values? I dont have a clue what I am doing when It comes to tweaking files.

Sounds like you got it. The same affect was seen in SH3 GWX...fuel consumption went up and crew wore out faster.

Now, need to package that for easy installation:yep: Excellent work!

[Fearless]

Yes, looking forward to a more bumpier ride. (Make sure u have an empty bucket beside u though!! :lol: )

[CaptBC]

Anyone know where we can find actual mass (RL) of the boats in the sim?

Bob

[t0maz]

In the Sim Cfg I put Waves Amplitude=0.85 and Waves Attenutation= 0.05 i'm still experimenting with these values though.

Watch for Waves Attentuation. Probably when it is lower than 0,75 sub will use compressed air -> http://www.subsim.com/radioroom/showthread.php?t=113316

Displacement = mass? Not really sure tbh and I think its in pounds, but Im not sure. Either way the mass in the .sim file needs to be below the displacementsurfaced. If the Mass value is higer than the displacement value the sub will remain sunk below its normal level.

After adjusting the gc_hieght, the mass, max_elevation, min_elevation, elev_min, and elev_max, I notice my boat seems to want to stay a few feet above my designated depth. Any idea what would cause this? Ex: I call for periscope depth, but my boat only goes 39 feet down (sboat periscope depth =47.5ft).

[Kataki]

I figured new question is worthy of a new post..


I am currently tweaking the S-18 and here are the values I am using if anyone else wants them. These arent 100% where I want them but tweaking them is tedious at best. That said, I feel they are a big improvement over the original values (keep your orignal .sim somewhere safe)

restr_dist = 200
maxTraverse = 153
minTraverse = 207
speedTraverse = 20
maxElevation = 103
minElevation = -103
speedElevation = 12
trav_min = 350
trav_max = 10
elev_min = -103
elev_max = 103
mass = 845
gc_height = 1.4
fr_ratio = 0.5
put_on_water = 1
displacementSurfaced = 850
draughtSurfaced = 5.257
dragSurfaced = 0.5
displacementSubmerged = 1126
draughtSubmerged = 6.6
dragSubmerged = 0.5

Hope someone likes them.


Biggest problem I have with these values is the fact the crew goes inside the sub at an abritrary depth that has absolutely nothing to do with the actual depth under the water of the sub. 33 feet on the doesnt mean the sub is actually under 33 feet of water but rather its altitude is -33 ft. In calm weather 33 ft on the depth gauge means they are underwater, in stormy weather 33 ft means they are in the valley of a wave. A possible (dirty) solution would be to change some setting to allow the crew to go under 33 ft of water and just have the user use his judgement as to when they need to be in the sub. Anyone see this as feasable?
