speed of torpedo?

[Pawian]

Hi

I play silent hunter 3, patch 1.4.

I elaborated complicated system of torpedoing. Distance from u-boot to enemy ship, and angle between him and our uboot.

Then I use trigonometry to count distance, where enemy ship will be when our perisopce is 0.

Now i need tip how i can choose torpedo speed, so i can fire it at the appropriate time.

I dont ask about TDC and - slow medium or fast, but mannualy choosing torpedo speed for example 20 kilometers per hour or 30.

Help pls.

Welcome aboard, Kaleun Pawian.

The torpedo speed settings are fixed.
The electric eels are limited to 30 Kts (or better 28Kts unmodded - its a bug)
The steamers are fixed to 30/40/44 Kts iirc. There were no other speed variations available with the German U-Boote until later in war. Homing torpedos had different (fixed) speeds and some rare long range versions (Dackel) were going realy slow (not simulated in SH3).

You can change the settings to other fixed speeds via modding - but then again you should have only this given sheme of one speed setting for electric and three speedsettings for steamers.

There is no ingame choice other than given/modded set.

hmmm, so whichc mod i need to choose torpedo speed??

I want speed value that I want, no only 3 of them...

There is no way to have more than the given speed settings. You can only change the fixed speed settings to some other fixed speed setting.

You won't have any ingame flexibility to set any speed variation but the given ones.

skwas Silent 3ditor is the modding tool - you'll find it here aboard.
A forum search for 'torpedo speed modding' or similar will show the files to be altered.

As far as I know there is no existing mod available with altered speed settings. You will have to mod them by yourself.

Edit: Your complicated trigonometric approach would be fine, if there were more variable speed settings for the torpeodes. But there aren't.
Do your math with fixed torpedo speed and variable angle of attack. That's what they did (or the TDC).

if there is no possibility to change torpedo speed, whole method is useless....

True.

Let's see...

There are three G7a torpedos available - the original one, the FAT and the LUT.
This may enable nine speed settings (3x3) - via modding. Not sure if doable.
Additionally there are four G7e torpedos - TII/TIII/FAT/LUT.
Another four speed settings (maybe more if they can be converted to 'G7a types' - via modding. If so there would be 12 more speed settings).
We have two (or 3?) Homing torpedos. If it is possible to deactivate the acoustic warhead, you'll have two/three - or if convertable to G7a types six/nine - additional speed sets.

At best you could have 30 different speed settings. But you could have only six loaded into your tubes and some 20+ into a type IX (I don't know the capacity of a type IX - never played it in the last ten years). The XXI may have even more loadout?

You would have to make all torpedos available in your timeframe. This has been done.
