[TEC] Crew Below and Diesel cut-off depth - hard-coded or tweakable?

panthercules · 01-30-08, 12:32 AM

Nobody has any clues? The only parameter I've found so far that does this unfortunately also lowers the entire sub so it rides too low in the water. I've had to abandon a couple of otherwise very promising looking Pitch combos because of this one issue, so it would be really great if someone could find a painless way to tell the crew to stay on the bridge until a deeper depth was reached.

The appearance and dis-appearance of the crew from the bridge is controlled by the surface draught value.

The on/off of the diesel engine is controlled by the submerged draught value.

Adjusting these values has an affect on submerging to a ordered depth. For example, if you set the submerged depth to say 20 metres and order periscope depth, then it will not submerge, you will need to order depth of 21 metres.

The submerged draught also controls how the sea affects or does not affect the submarine. That is, if you were to set the submerged draught at say ~1 metre above the periscope depth, then at the periscope depth the submarine will now be affected by the waves

Panther, I can't help you with the tweeks, but from experience, the first command from the officer of the deck would be...usually... conn..bridge...prepare to dive...then...Lookouts clear the bridge...Dive Dive, the lookouts would then ladder down to take over the dive and stern planes. The first officer off the bridge would hold the conn hatch rope while the OD locked it down. Everone had cleared the bridge very fast. The stock version of SH4 clears the bridge way too late. The OD, when in the conn, would then give the control room the depth he wanted. This would vary depending on the reason for the dive. But, this was peacetime.

Also I've been trying to get the subs to sit deeper in the water. I don't know if its the waves or the surface depth of the boats, but they seem to sit too high. We didn't cavatite that much. The stern seems a bit higher than the bow to me. We didn't roll as much as one might think. The pitch was the greatest in ruff weather.

I do recall Dave/Leo looking into lowering the submarine in the water. I believe he said at a certain point of lowering the submarine, it would just sink for not reason other than he lowered the sub in the water.

Bump!

Shutting down the diesels is the very first thing that happens when the dive order is given.

Quote:

When the diving alarm is given, the following procedure is observed (items marked with all asterisk are executed at once without further orders)

*a. Stop all engines, shift to battery, set annunciators on "All ahead standard," open engine room doors and air locks.

*b. Close outboard and inboard engine exhaust valves, close hull ventilation supply and exhaust valves, close inboard engine air induction flappers, and close conning tower hatch.

*c. Open bow buoyancy vents and all main ballast tank vents, except the group or tank designated to be kept closed until pressure in the ship indicates that all hull openings have been closed.
*d. Rig out bow planes and place on FULL DIVE. Use stern planes to control the angle on the ship.

*e. Diving officer checks hull opening indicator light panel for condition of hull openings. Air is bled into the ship when green lights show all hull openings closed. Watertight integrity is assured when the internal air pressure remains constant.

Good info on the diving procedures etc. I'm not really trying to affect anything about the actual diving routine however. My problem is, my best candidate visually for my Pitch mod currently has one unfortunate side effect that I have not yet been able to get rid of - for the first few minutes after surfacing, the boat tends to rise and fall with the waves in a narrow band that just happens to be where it sinks down just barely lower (by only 2 or 3 feet it seems) than the cut-off depth where the game sends the crew below, and then back up to where they come back up top. The net effect is that the crew keeps disappearing and re-appearing 2 or 3 times a minute for the first few minutes.

The really frustrating part is that this only occurs right after surfacing - they stay up there just fine after a few minutes, once the boat picks up speed. If I could just drop the "crew goes below" depth by about 4-5 feet, without changing the boat's actual dynamics, it would solve this problem. As DTB points out, the surface draught value (which is the one I was referring to in my second post above) does affect this depth but it also screws up the boat's behavior too substantially to be a workable fix for this particular problem

It's really great that the devs gave us so many things to play around with - it's just too bad that so many of them seem to be multi-purpose things that affect several functions so it's hard to hone in on making the particular change (and only the particular change) that you really want to make.

The only way I can think of to get the deck crew below decks or back to topside at the correct time would be with a voice command, and not with the depth. This may not be possible.

Its times like this I wish I knew more about the inner workings of the sim.

Sorry I can't help you more Panthercules...
