Torpedo question - automatic targeting on TMO

Jonesy · 03-31-17, 09:30 AM

I've been getting back into SH4 with the TMO mod after spending some time with SH3, and I found a small difference of behavior with the torpedoes that I hope someone can help me with.

Now, I play with automatic targeting turned on, and on SH3 I was pretty used to using the 'lock' option on the periscope, it would lock the crosshairs at about midships, and you could be pretty certain that the torpedo would pretty much hit more or less where it was pointed out, taking into account that you got into a good position before shooting, and shooting from about 600 m away.

now, on SH4 TMO, i have found that using the same tactics does not produce the best results....the torpedoes seems to hit further back on the ship, and sometimes just miss the back, this is shooting at merchant ships that were not aware of my presence before the torpedoes were fired.
I have found I get better results by not using the lock option, and instead manually pointing at the very leading edge of the bow of the ship....and then I get a hit closer to midships.

It seems to me that either:
1 - the speed of the ship is getting underestimated by the automatic targeting system
2- the torpedoes are running slower than the speed that they are set to.

In my current career I just got the report for the battle of midway, to give you an ideia of the date in case this is related to torpedo behavior.

Could someone shed some light as for the the reason for this?
-am I doing something wrong?
-is this just the game simulating some sort of irregular torpedo behavior?
-is the game just simulating that maybe I have a green crew member calculating the ship's speed?

thanks in advance.

some possible causes:
Did you open the Torpedo tube before lining up the shot? Takes a little time to open before the torpedo shoots out at the point in the ocean you selected. (ship has moved some by then) I never had SH3, maybe it didn't have this kind of delay.
Did you wait a little bit of time between selecting and firing? (similar situation)

Or, others can answer, is it something in TMO?

Yes, I always open the torpedo tubes before firing, since I am still learning my way around SH4 maybe I am slightly slower between selecting the tube and firing, but I don´t think there is a big delay there.

Not opening the torpedo doors is the most common cause of your error.
TMO doesn't change targeting behavior. It will change ship and torpedo behavior. If you're running TMO only, it may be ship behavior. TMO changes all AI to the highest level. The ships may have spotted your periscope and took evasive action. Just a minor turn or speed change will cause you to miss, especially from a long distance. I will fire a salvo of three or four aimed at different points along the length of the ship. I use auto-targeting and don't bother to lock on.

Playing again yesterday I realized what my mistake was.

I was hitting the button to open the torpedo doors, but I was firing too soon and the doors were not totally open yet...causing a delay.

mental note, the torpedo doors take longer to open in SH4 than they do in SH3 ....check

thanks a lot for the answers

Somebody was working on a mod that would add something to indicate outer door position for each tube, dunno what happened to that. Meantime what I did was use Silent3ditor to open the NSS_(subtype).sim file for each type of sub, select the wpn_SubTorpedoSys, and change auto_open = True to auto_open = False . That prevents the tube from firing at all unless I manually open the outer door, and I got into the habit of opening the outer doors long before the target is in firing range. To my way of thinking that's the best way to deal with a flawed feature, if it can't be fixed then disable it.
