Auto TDC consistently misses (torps arrive late always)

Koinonos · 03-26-07, 05:06 PM

I am in my first SH4 campaign as a SHIII veteran and am getting a really confusing problem.

Essentially when I have perfect AOB and have merchants crossing my front at 500 meters to 1500 meters I cannot get a torpedo to hit a merchant. Whether I am locked on the target or manually moving the scope to get a firing solution on the forward tip of the nose of the vessel the torpedos (at slow or at fast settings) will never hit the target.

Leaving the sub I can tell by 25%-50% of the run time it will never arrive in time to hit the ship becuase the torpedo was not fired ahead of the target to meet it at it's speed and distance.

I have tried this in 2 different subs and 2 different campaigns (ver. 1.1) and the torpedo *always* arrive .5-1 ship lengths too slow. The problem is consistent and reproducible - it's like the TDC computer is 10 degrees retarded always.

I go back to SHIII and my targeting is dead on, so it is something with SH4 but darned if I can figure out what.

What I've Tried:
=============
1.) Different Sub - Problem is reproducible of the TDC regardless of sub.
2.) Locking on target vs. manually leading the target using the periscope to the nose of the vessel to attempt to lead more - No effect. Torpedo always arrive .5-1 ship lengths too late.
3.) Changing distance from target - No effect. The torpedo will always arrive .5-1 ship lengths behind at 400 meters or 1200 meters.
4.) Changing speed of torpedos - Setting to fast or slow makes no difference. The torpedos will still arrive .5-1 ship lengths behind.

What I'll Try Next:
================
1.) Try different torpedo classes - Maybe it's a bug TDC computing with the larger Mk 14 steamers?
2.) Go back and play the sub training in ver 1.1 (I qualified when SH4 was ver 1.0) and see if the problem occurs there as well..

I am really drawing a blank here. Has anyone else observed this effect? I cannot get the TDC to compute a proper firing solution.. It's almost like something is consistently being miscalculated.

I have this same problem. It first came about the very first time I tried the game - in the torpedo training mission. You can lock center ship and fire with tubes already open and lucky if the torp clips the aft of the ship if not miss completely.

And it is reproduceable - happens every time I fire a fish.

Perhaps you are being too cautious. Get in closer to your target!!!

EDIT
I had another thought, set your torp speed to high. Last nite I sank the Yamato but I was vey close, less than 1000 yds, and it took six fish.

Known bug, AFAIK.

PD

lol

he´s at 500meters...

close than that he could slap the captains face !

Rykaird · 03-26-07, 05:27 PM

Yes, lots of folks have confirmed and posted on this. That cruiser in the torp school has a lot holes in his hind end! To my knowledge no one knows the root cause.

The usual advice is to make sure your bow cap is open, that you update the TDC with range (and therefore bearing) right before you shoot, etc. If you do all these things, the torp still goes aft, so its clearly some kind of a bug.

Until addressed, you can compensate by adding a few degrees with the salvo switch or a few knots of speed over the actual speed of the target.

tommyk · 03-26-07, 05:31 PM

Same here. afaik a bug...

Torpedo tube doors open agonizingly slow.

At any rate, spread angle is your friend. If your target is moving to the left in your periscope, use about a 4 or 5 degree Left spread angle. If your target is moving to the right in your periscope, use a 4 or 5 degree right spread angle. Hit's every time.

This works to help alleviate the problem, but one thing to add: Of course a 4 to 5 degree angle will work at close range. Farther out, you may have to cut this number down. YMMV and all that.

malkuth74 · 03-26-07, 05:51 PM

You need to update the Bearing and Range in the torpedo settins menu. If you don't you will miss. (thats the little round button on lower right of the menu that turns white)

Their is a bug, but its not that off if your shooting AUTO and at 500 Meters.

Push the button, it works. Even though its not the Mark button that US subs have. I think of it as one.

gnirtS · 03-26-07, 06:08 PM

Seems to be a known issue.

Are you using auto or manual TDC ?

See this thread:

TheSatyr · 03-26-07, 06:08 PM

Is it possible that your crew quality may be causing the problem? A less experienced crew might be making slight errors in the auto TDC,causing torps to pass behind the target.

Has anyone tested the auto TDC with both an experienced and inexperienced crew to see if there is any difference in targeting?

(The same thing happens to me in vanilla SH3 with my WO. He aims better as he gains experience it seems).

shawnyp420 · 03-26-07, 06:09 PM

Yah, this is really annoying. Did they test this game at ALL!!??

I mean...there is a HUGE community here on subsim...Why couldn't they just ask 50 of us to test the game? All of these stupid bugs could have been fixed. Don't you think the Auto TDC would be something that they would notice?? I have a serious lack of confidence in devs if they overlook a MAJOR bug like this one. Let's see. Submarines shoot....torpedos. So...let's make sure the torpedo shooting isn't bugged right!!? I'm not trying to flame here...but...wtf!?

And before you start bustin me for using the Auto TDC...Look. I'm the captain here. I should be giving orders...thats it. When I say FIRE. I expect that my fish will hit!!!

Yes and at all level crew from poor to vetern they miss by the same offset. Its not a crew quality problem.

DJSatane · 03-26-07, 06:26 PM

damn i am glad i dont use auto tdc, although manual tdc is very clumsy as well, but at least I got hang of it mostly, except speed determination is very annoying since built in feature doesnt work.
