Who said flying torpedoes were history with DW?

Guess what I saw...

I could show the screenshots had I not pressed the wrong keys at the time

It's not the eternally flying torps of SC, at least.
Here's what happened:

A passive torpedo was speeding along at 40 knots (setting 35), homing on a surface craft. It would seem as if the torpedo held the contact only intermittently, as it suddenly, when being closer horizontally than vertically, decided to go straight up. It missed the ship (would have been some scene even if it hit though :|\ ) and shot up from the surface.
(This should be reproducible with changing the doctrines also)

True to life, it fell back down - but backwards. And falling into the water, it took less than a second before it was back at 40 knots forward and shot up again.

It took around 20 hops before it had pitched down enough to go back down beneath the waves.

This episode highlights problems with the physics engine; the amount of thrust applied is too great. This is also the reason subs accelerate 0 to max in way too short time, and probably more things as well.

I don't know if the following is a separate problem or an illusion created by the previous one, but it seemed as if, with the exception of plain falling (torp in air, slmms in water), objects are utterly incapable of a speed vector in a different direction than their nose.

I have seen this as well.

You can reproduce it by reducing the turn radius of the torpedo in the database. This works (the reproduction of the error) particularly well with SUBROC, airdropped, and torpedoes with speeds over 55kts.

Seen many times, I even considered doing demo funny doctrine where torps attacking ships would jump out of the water and fall on it's deck

The very positive thing is that torpedo falls back to the water in DW

If the thrust is too strong... maybe, but the ability to jump out of the water - at least once - is very real for every object moving at speed of over 60mph or almost 30m/s

Actually torpedo going 30m/s (so about 60kts) if went straight up, could jump as high as 45m / 150ft !!!

I'd like to see such a doctrine in action

Anyway, when it hit the surface on its way back, it should have about the same speed it had when it broached the surface to begin with, just downwards - and that speed is probably not reversed in less than a second.

As I said, I believe this is similar to the subs high acceleration.

LMAO

I reported this when the demo came out!! It took you this long to notice it. :rotfl:

noticed it seen it had it happen

bit like when i was firing udaloys
