Ship Dynamics - Pitch and Roll?

"I may have to find a way to eliminate him"

If you really want to eliminate him just delete the lso.gau gauge, but you probably knew this.

Interesting thread. I for one appreciate your testing. I think many of us have known this needed to be done but never took the time. The video and pictures really bring it home. Thanks! :applause:
 
I'm curious, What do you use for a moment?? You can't have a carrier pitching and rolling like a 8 foot pram.
It would be a 10 or 15 second moment in roll and probably 5 to 10 seconds in pitch.
Plus the pitch was not a constant. Every ninth wave would be a doozer. Sometimes, come right over the flight deck.
Maybe you should have a sequence, play it and then repeat itself. Does this make sense to anybody?
 
Sorry Helldiver but the "dynamics" is worked out by the cfs2 engine, it isn't a special effect. We cannot at this time change the timing, (though if the engine works it out by the length of the vessel we may have a chance).

regards Collin:ernae:
 
Stand by Helldiver and Collin. I'm gonna do more testing with a "jeep" carrier like Collin suggested and see if I can get a visual on BBs CAs and DDs to boot.

Having a bad day and must take a couple of pain pills and lie down... I'll get to it though.

Thanks fot the "atta boy" Cody and Collin :jump:
 
Done... I used the VN North Carolina Class BB, VN Baltimore Class CA, VN Fletcher Class DD and Collin's beautiful CVE Sicily, all sailing at 25 knots (no wind) and all set on:

[Dynamics]
pitch_wave_moment_scale = -3
bank_wave_moment_scale = 6
pitch_damp_moment_scale = 1
bank_damp_moment_scale = 1

I didn't take any screenshots this time but I took some good on deck views of all the ships. The BB and DD don't seem to pitch as much as I expected, but everything looked cool. As you will see it was difficult to hold the ships in the center of the field of view, but I did the best I could. :typing: I did two take offs and landings in the video:

http://s81.photobucket.com/albums/j220/Pechora07/?action=view&current=PitchnRoll2.flv

I may set all my ships to that setting ecept for the carriers, which I'll probably set to:

[Dynamics]
pitch_wave_moment_scale = -2
bank_wave_moment_scale = 4
pitch_damp_moment_scale = 1
bank_damp_moment_scale = 1

so it's not so obviously vilolent on the carriers :monkies:
 
:: Urp... :


SW, that's a little TOO realistic for my stomach...

I watched about 20 seconds of your vid and started gettin' that old time seasickness.....

Which, I suppose, is an odd form of compliment !

SC
:kilroy:
 
Good work Shadow, playing with that 'little'un' will help yer landings on the bigger one's:wavey:

Having the dynamic's set too high can bounce you off the deck, I wonder if Psullykeys has put dynamics into those ships he is testing? Then sc7500 could really appreciate the rolling:faint:

regards Collin:ernae:
 
Upon further analysis...

W/ regard to Helldiver's comments...

I find that for Carriers (both fleet and jeep):

[Dynamics]
pitch_wave_moment_scale = -4
bank_wave_moment_scale = 4
pitch_damp_moment_scale = 1
bank_damp_moment_scale = 1

has the best combination of dynamic deck motion, ...

...and smooth, ...large ship sea motion.


Have reset all the CV/CVL/CVE's to reflect this delta.


Thanks for the input (and the service) Helldiver.
 
I've had a stroke so don't remember so good with hole in the brain. But I can remember writing some code where you could set up a set of statements and then go to return to: and start the whole sequence up over again.
Will some old MS DOS guy help me out here. I know it can happen.
 
wave_moment = magnitude of movement, effects wave height

damp_moment = speed of movement (dampen means "to stiffen", the lower this value the slower the overall movement from crest, the highest point, and a trough, the lowest; lower bank_damp slows rocking as well)


Sorry, had to correct that last part of my comment...

In my tests...

The period (time) of both the pitch and roll motion is constant, ...

...and the roll is twice the pitch. (2R = P)

Increasing moment to either one just increases the amplitude of the motion, ...not the period.

The Damp seems to be an inverse function to Moment.

i.e.

Moment = 6
Damp = 3

Dynamic = 6/3 = 2

EDIT:
P.S For that 4,4,1,1 Carrier Dynamic....

On the stock Essex at stock spot location (-70), ...the deck heave is twenty(20') feet (+10/-10).
 
Now in real heavy seas the Destroyers put in for Sub pay. Everything is covered with water, except for the top of the mast and the stacks. That's why the stacks are so tall. I got pictures of them somewhere.
If there are any Destroyer men out there, they will vouch for what I'm saying. 'Course the reverse was true, when they come out of the water you could hear the props scream and the whole bow would be out of water.
I'd like to see a movie when you guys are through.
 
Helldiver, I spent a few days here and there at sea. I much preferred the USS Blueridge and carriers to LSTs and DEs.
 
There is a way to whack the LSO - I did it back in the day - 2001 or so - but don't remember how to do it - what CVs are you using? They look fantastic! Nice video! Stand by for Operation "Hailstone"!

GR
 
Sure....

See Cody's earlier post, or you can just close his window when it opens.

The CVEs are Collin's from CG's Shipyard.
:wavey:
 
Shadow,....

....while you're testing the movement settings, why not test the LSO settings in the Ship.CFG file at the same time?

Kill two birds...so to speak.:engel016:

1. CFS2 main folder/"default_panels.cfg"/

[Window00]
window_pos=0.36,0.26
window_size=0.16,0.21
size_mm=66,66
nomenu=1
sizeable=1
visible=1
type=SPECIAL
ident=LSO_WINDOW

;gauge00=lso!lso,0,0

Just add the ";" in front of the gauge line.


2. CFS2 main folder/GAUGES/"lso.gau"

Just re-name this gauge file. (though the prog will look for it, ...so use option 1)
 
"There is a way to whack the LSO - I did it back in the day - 2001 or so - but don't remember how to do it - what CVs are you using? They look fantastic! Nice video! Stand by for Operation "Hailstone"! "

GR, I used Collin's CV's - Essex Class 44 and his CVE Sicily - http://www.simviation.com/lair/cfs2shipyard.htm

You can take the LSO out completely by doing as Cody Coyote said: in the Gauges folder, rename the lso.gau file or delete it entirely. Or use BD's suggestion to turn him off (above). Also, in each game you fly, you can Pause and right click on the rascal and close the window. Thanks for the compliment. :)

TR: I don't know how (what numbers to change) to adjust the settings other than to make the LSO window larger or smaller.
 
LSO Training

Here are a couple more tips on the LSO and his performance (or lack of it).

1. You can vary the LSO window size and location by editing his data in the default_panels.cfg file.

[Window00]
window_pos=2.03,0.03
window_size=0.16,0.21
size_mm=66,66
nomenu=1
sizeable=1
visible=1
type=SPECIAL
ident=LSO_WINDOW

If you want, you can make the window very small and put it up in the top or bottom corner of your screen to get him out of the way but still keep him on salary.

2. You can also adjust his signals to allow for faster or slower aircraft. Go to the Aircraft.cfg file and (add if not present) edit thie following:

[LSO]
LSOAdjustSpeed=0.65

As I recall, a higher number is used for faster approaches and a lower number for slower aircraft. As this data entry is or can be in each aircraft's .cfg file, you can vary it for jets to biplanes.

3. LSO removal. I get a black window when I just turn off the gauge so I also turn off the entire LSO window with a semicolen. Again, go to your default_panels.cfg file and:

[Window Titles]
;Window00=Landing Signal Officer

;[Window00]
window_pos=2.03,0.03
window_size=0.16,0.21
size_mm=66,66
nomenu=1
sizeable=1
visible=1
type=SPECIAL
ident=LSO_WINDOW

I guess just turning off either entry would work, but it doesn't cost anything to turn both entries off and it works well.
