[WIP/TEC] Roll/pitch enhancement

[Kataki]

I am currently trying increase the roll/pitch of boats to a point I feel is more realistic, and will release if anyone would be interested in it etc. I've ran into a few problems though and was wondering if any of you more experienced modders had a solution to it.

I tried created the roll by increasing the mass/gc_height and increasing the max/min elevation but these values seem to have affected my ships ability to dive. My porpoise for example only goes to about 41 feet deep, period and refuses to go any deeper no matter what. The s-18/42 class boats will dive as deep as you want but seem to reamin roughly 8feet above thier designated depth. Does anyone have any idea what values would affect this? If I cant figure this out I'll just leave this to someone who knows what they are doing :P

I am definately interested in this. Sorry I can't help, but best of luck.

Had the same problem... I think it has to do with the 'mass' value... anyways, using TT's MiniTweaker, I set maxelevation @45 and minelevation @-45.... I left mass @ 0.. I set the gc for S-18 class @3.5... for all the others, I set gc @3.25.... seems to work pretty good... no more shallow PD-broaching... or bad depth control...

If you set gc at 3.8... your boat will probably roll upside down... so, I suspect 3.5 -3.7 or thereabouts is the upper limit... I have no idea if gc is meters or feet... or what the reference point is... just remember... the center of gravity ... measured vertically... cannot exceed the center of bouyancy... measured vertically... by too much or else the boat will lose its righting moment and flip upside down... but, to get that true 'seasick rolling' effect, the gc must be set higher than the center of bouyancy (bc)... just my 2 cents..

I'm very interested in this too, but I'm afraid I'll be no help in figuring out the best values as I never had to look at these for SH3. I'm hoping the developers eventually address it as at the moment the boats really feel like they're on rails. One thing I did do in RFB was to reduce the wave trough depths so that the boat didn't appear to float through the air from wave to wave, but I don't think that info will help at all with pitching and rolling.

trimzeke....

would you be so kind and offer your file for download... ???

My values for the sboats if you want them:

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

I dont think you can simply pack them up without overriding other mods, you have to use the SH3 mini tweaker to use them. Its not really that hard to learn to use, I r teh n00b too and I fIgured it out

Bah still no luck in figuring this problem out, I dont understand why i can make the S boat work farely well but anything bigger seems to have problems diving when I try to tweak the values =/

After today I wont have much time to work on this due to finals etc


@ Beery, Aye I did that as well, definetly helps a bit.

OK, I'll give it a shot. You should be able to find the download .rar file here: http://hosted.filefront.com/trimzeke/

Ok another setback, I can't seem to get these values to affect v1.2. Using 1.1 these values actually got the affect I wanted, but now its the same old same old, a boat on a rail.

Would using the generic mod enabler and then using the sh3 tweaker cause this ? I didnt use the JSGME before.

[Schunken]

thanks for the download trimzeke

@kataki... very puzzling... these are 1.2 NSS****.sim files that I tweaked with TT's Mini-Tweaker... using JSGME should have no effect on them... I use it all the time to activate-deactivate mods with no side effects... if you tweak them yourself with the MT, then that will definitely cause some changes though.... remember, I set the mass value to '0' because of strange depth control problems... and the gc value less than 3.8.... with min and max elevation set to -45 and 45... that's all I did... I get lots of movement on all the boats, especially the big fleet boats.... it's not real dramatic, but is still 'ocean rolling'...

[Kataki]

Thanks for the info, I guess Ill just keep messing with it on and off until something happens :P

Edit: Well for whatever reason I can change the files now and I was messing around and changed the gc value to 4 and the boat is upside down lol good stuff

Edit2: Hmm after testing some more I am definetly affecting the boat, but not in the same manner as before. The boat still looks as though it is on rails. Does your boat still look like its on a rail trimzeke especially when you leave the mass at 0?

Edit numero tres: I feel stupid now, but I forgot to change the sim.cfg file They made a HUGE difference. When I use a mass of 845 with the sim.cfg I get a dramatic effect, but along with the depth keeping problems. At best its around a depth difference of 8ft, but I think it increases with depth.

[Mech]
Waves amplitude= (atm I am using .65)
Waves attenuation= (atm I am using .15)

[Beery]

I changed the Waves Attenuation to 0.01 and the boats seem to pitch and roll more realistically, but the downside is that they have trouble staying surfaced.

[Beery]

I just took out an S-18 using a wave attenuation value of 0.03 and waited for a 15m/s storm. I found one after a few days and took the S-18 through a few tests. The boat dived okay and surfaced properly (I tested this three times just to be sure). The 'flying from wave top to wave top' thing doesn't happen (although it's not quite as good looking as the 0.01 value. Better still the sub no longer travels on rails - it pitches and rolls more like what we were used to in SH3 (but not too much - about what I'd expect for a little boat like the S-18). I also did two long periscope depth dives to the full extent of the battery and I had no problem with leaking compressed air.

I think we've found the sweet spot guys. So you might want to try adjusting the wave attenuation to 0.03 on your games and see if you get good results too. I'll test other boats later today or tomorrow, but since the S-18 was the boat having problems I'm hopeful that this has cracked it.

Note the only difference is the Waves Attenuation number - all other boat sailing and wave stuff is the same as stock SH3.

I'll give .3 a try, what wave amplitude are you using btw? And you say you didnt notice any depth problems?

It's 0.03 and wave amplitude as stock SH4 (0.2 if I recall correctly). I haven't noticed any significant depth problems. The boat might be a few feet off when deeply submerged, but nothing really noticeable. The only real problem is that the 'flying sub' issue is not completely removed as the boat rides a bit high in heavy seas.
