DD not responding to attacks?

AVGWarhawk · 03-03-10, 04:01 PM

CCIP, does the game offer rookie up to elite like SH4 does with warships?

CCIP · 03-03-10, 04:05 PM

yeah. I've not looked into it too deep, but the "levels" look to be identical. And the vast majority of everything in early game is rookie.

ASDIC comprised a transducer housed in a dome beneath the ship that sent out a narrow beam of sound in a series of pulses that would reflect back from a submerged object within a maximum range of about 3,000 yards (2,700 m). The dome was open to the sea and was to ensure the water around the transducer was relatively still as fast moving water would destroy any signal. The echo produced an accurate range and bearing to the target. But differences in the temperatures at different depths could create false echoes, as could currents, eddies and schools of fish, so ASDIC needed experienced operators to be effective. ASDIC was only effective at low speeds. Above 15 knots (28 km/h) or so, the noise of the ship going through the water drowned out the echoes.

The early wartime Royal Navy procedure was to sweep the ASDIC in an arc from one side of the ship's course to the other, stopping the transducer every few degrees to send out a signal. Several ships searching together would be used in a line, a mile or a mile and a half apart. If an echo was detected, and if the operator identified it as a submarine, the ship would be pointed towards the target and would close at a moderate speed, the submarine's range and bearing would be plotted over time to determine course and speed as the ship closed to within 1,000 yards (910 m).

Once it was decided to attack the ship would close more rapidly, using the target's course and speed data to adjust the course. The intention was for the ship to pass a little way ahead of the submarine, then depth charges would be rolled from chutes in the stern at even intervals and depth-charge throwers would fire further charges some forty meters out on either side. The intention was to lay a depth charge 'pattern' like an elongated diamond, hopefully with the submarine somewhere inside the pattern. But to effectively disable a submarine a depth charge would have to explode within about six meters, in depth as well as in plane. Since early ASDIC equipment was poor on determining depth it was usual to vary the depth settings on part of the pattern.

There were disadvantages to the early versions of this system. Exercises in anti-submarine warfare had been restricted to one or two destroyers hunting a single submarine whose starting position was known in daylight and calm weather, rather than stormy conditions. German U-boats could dive far deeper than British or American submarines, to well below the deepest setting on the British depth charges (A dive depth of over 700 feet (210 m) against a maximum depth charge setting of 350 feet).

More importantly, early ASDIC sets could not look directly down, so the operator lost 'sight' of the U-Boat during the final stages of the attack, a time when the submarine would certainly be manoeuvring rapidly. The explosion of a depth-charge also disturbed the water so that ASDIC contact was very difficult to regain if the first attack had failed.

Heh, i wonder if the DD's have proper sonar, hydrophone nodes. That would do alot to break things. SH5 used Sh4 as a base. In SH4, not all ships had ALL the proper nodes assigned to them.

edit:
another item might be thermal layer effects being carried over from SH4. Check the sim.cfg and make sure they're aren't any. If those variables are high enough, you become invisible underwater for all intents and purposes.

Good point, I'll have a look.
Looking at the folder and file structure of the game, it seems like a lot of stuff has been recycled from SH4, which in turn had a lot of stuff recycled from SH3. (I remember making a Soviet Office mod for SH4, and whilst I was looking for office textures, finding all the graphics for the SH3 office!)
It could well be that I easily evaded those 3 destroyers because of the thermal layer attenuation. I'll have a look.

Well the DD are pushovers in vanilla because as a new comer who wants DD that sink your butt all the time? NO fun in that. Sinking ship, shooting down aircraft and going head to head with a DD is fun....if you can win most of the time. SH4 DD were quite unresponsive....until Ducimus screwed with them and a few others that made them diabolical

I have no idea what your talking about.

Honestly though, If i do one mod for this title, I wouldn't mind doing this with K guns instead of Y guns. I could achieve a much better pattern.

However, i have to finish next update to TMO first, ive been procrastinting too long, and this game needs more patching.

I agree, don't "waste" your efforts on it quite yet. I think right now the focus for modders should just be basic stuff like quick tweaks and easily-transferable graphics files. Everything else should wait until the devs clean it up a bit.

Oh absolutely....SH4 has more Ducimus massaging needed.

Will always be my favorite! CCIP is correct.

Looking forward to your work/efforts....now how much was that wager for again?

If you buy the game and mod up , i will buy it too .

Just what I thought. SH4 was the same I believe when fresh out of the box. Ducimus is very familiar with SH4 workings and nodes as he notes. DD will needs some help then.

I have been a little concerned about the enemy AI too.
My watch crew seem a little bit myopic. They only see aircraft at about 3000 meters at the moment (may be something to do with morale or experience? dunno yet). By the time I order a crash dive the planes are pretty much flying right over me.
But - this is the thing.
The aircraft never seem to actually spot me, even though the nearest pass was about 400 meters.
Tried a single mission attacking a convoy. Instead of attacking I decided to get noticed and see how easy it was to evade.
Flank speed to the convoy until I got a visual.
Then ran at flank speed at periscope depth at the nearest DD.
Circled around at flank speed till I got the attention of 3 of 'em.
Admittedly is was ****ty weather.
But still.
There was three of 'em. I evaded them pretty easily.

Couple of things spring to mind.

1. I have played SH3 and SH4 extensively so I am conversant in sub evasion techniques.
This may have helped me out here.

2. I remember in STOCK SH3 and SH4 the escorts being a bit of a pushover.
I suspect that this is more the case here.
