[WIP] U-Boat Killer AI Mod

[Heretic]

Thanks. I think I always had something selected in the 2nd dropdown.

Downloaded, will start testing tonight or tomorrow.

Thanks Will-Rommel, feedback would be appreciated, so I can kill you all. I mean, improve the AI.

[Will-Rommel]

No problem, will report here as soon as i see actions. (Should be plenty of, it's the happy days)

Nisgeis,

I ran into 3 destroyers in Atlantic, coming at them head-on, decided to take one of them down and see what the rest would do, thinking presumably they will treat one of their own being hit as they would a merchant they are protecting.

So i went silent running, and went to periscope depth about 4 km away from the first destroyer heading the group, foggy weather so their visibility was poor. I kept engines running at about 3knots and hit the first one with two torps about 2km distance. He sunk almost immediately and i just kept same heading (through them).

I immediatley noticed that right after my torps hit, the remaining two Destroyers increased their speeds dramatically to 34-36 knots, but it took them a while to actually turn around, but they did, and then their lights came on and they started hunting for me. By that time i was at about where i had sunk the first ship and i just kept going. They started doing search patters with the lights but i had evaded the net -so to speak, they were a little slow off the mark to begin the search.

So while they werent hard to evade your mod definitely worked in that they noticed, and then started looking for the culprit.

Thats all so far, will let you know future enocounters.

Thanks Coldcall. They should get into the vicinity, but the current logic isn't very good - they'll just keep going around where they think you are, dropping DCs. I've got the lost contact procedure working, in that they now will do a spiral search (which was broken in two places, so even if triggered it wouldn't have worked). I'll also have the ammo saving in soon, with a weighting given to how old the contact data is - e.g. as it is now, if the sub was there five years ago, the destroyer will still drop DCs on that spot. Lost contact procedure is hit and miss, as you can travel quite a way from the scene of the crime and they are a bit slow to do a full circle. The 'thermal layer' is also acting like a cloak of invisibility.

Eventually, I will have different behaviours for different situations - e.g. if they are escorting a convoy their priority will be to keep you down and unable to get another shot off, if they are an HK group, they should stay around until you are dead or forced to surface.

All of this depends on realistic battery and CO2, if you are using infinite Battery and CO2, then it will be easy enough to outfox the AI, as you can travel a very long way at 7 knots underwater in an hour. Stay tuned for updates.

That "missing contact" routine would explain why it takes them a little while to start the active search. Is it on a refresh so they check for eachother every x minutes?

Also forgot to say they were dropping depth charges for a long time but nowhere near my sub.
