There is a now screenshot in the first page so you can double check that you have the right script-format in your file. And if you have still problems, please tell and I'll try to help!

Thanks for answer.
I´m using your code since the first day you posted here, not via jgsme, just directly (edited with notepad) and didn´t notice any CTD related with this. I´m happy with it.

Much better instructions now, thx Rongel. I misunderstood first time and thought we were gonna mess with the exe file

Thanks for the answer, Rongel

your picture say GetContactDepth() >= -13 and you describe GetContactDepth() >= -15..just a little adjust for liking?
Edit:
quote:So the only bad thing about this is that when the escorts lose you, they will bombard the last location 4-8 minutes causing possibly havoc. When they know you are deeper, they'll stop the firing.

(Had great fun with this.One DD bombarded the other )


Anyways I found that with GetContactDepth() >= -13 They never saw my scope until I was 13 m depth or less. short test with eange aob practice and fx update test They stopped when I took down scope but when I wenr deeper they just shot the "old "spot until my depth was above 13 m again regardless of my unmodded attackscope towering couple of meters above the surface. I put that to -17 the merchants never shot now but the dds started whit me just below 15 m. They never hit though . Not sure what to make of this.

SO now Im curious what this value does: ContactPresenceIs(PRESENCE_SENSORS, 15)

Edit: with -17 they didn t shoot at all. I really just try fail here

Now I tested with your test mission and it seem to work as purpoused. I put value to -15 again (GetContactDepth() >= -13) Felt weird that they could spot me with peri barly touching surface like they did when I put it to -17.
But what do they see actually? just periscope, or do they spot me like if I was surfaced when above this value? Can I cruise around at 15.5 meters and all is safe since I m to deep for shooting and too shallow for depthcharge? Anyways its a big step in the right directon thx

Thanks for the good report! Glad that you got it working!

Exactly. It's a small mistake, I've been testing what is the best depth value, right now using 15 meters.

SO now Im curious what this value does: ContactPresenceIs(PRESENCE_SENSORS, 15)

This is how I think it goes: If a enemy ship has located you with sensors (it can be any sensor: visual, hydro, sonar, radar) it can open fire if the other condition (GetContactDepth() >= -13) is true also. So it doesn't even need to see you, if dd's sensors show that you are nearby in periscope depth, it will try to shoot you down. There is also a script called ContactPresenceIs(PRESENCE_LOOKOUT, 0) which makes the ships attack you only when the see you visually, but I thought the current is more interesting and challenging. Not 100 % sure which is more historically accurate.

What makes things complicated is that the escorts react always in a different way. Some tests go just beutifully, like you would except, but sometimes escorts do something stupid, like shoot at themselves. Can't figure out why the escorts sometimes continue attacking you even if the script conditions are false. I guess they just want to sink you that badly!

Can I cruise around at 15.5 meters and all is safe since I m to deep for shooting and too shallow for depthcharge?

I think IRAI makes the escorts depthcharge you even if in periscope depth. I'm pretty sure I have witnessed this in my tests.

By the way, I did a long campaign play yesterday with this and had fun with Norwegian destroyer that I mistakenly thought as a neutral unit. I just cruised in periscope depth but then cannon shells started to hit the water breaking the radio and radar. I dove immediately and it stopped the shooting and started to drop depthcharges. It was like an angry bee!

Great mod, Rongel!

As of the realism of firing at a submerged submarine, to my knowledge most of the secondary naval guns had special anti-submarine shells, AFAIK they were diving shells - special shells with blunt nose so you shot it into the water and it did not bounce of the water but dived and continued for some distance submerged hopefuly meeting the submarine. Moreover you read in reports of real ASW actions that planes often strafed the spot where the submarine had submerged with their guns, I recon that it is modelled in the AI logic by developers, that is why, I recon, the ships continue to shoot at the last known spot for some time with your mod as well since they use plane's script, I recon that is realistic as well - why would a ship not want to shell the last known spot knowing that the sub is relatively slow to escape? Imagining myself as a DD captain I think I would still fire guns at last know spot for a couple of minutes even if I did not see the periscope any longer and even if I did not have ASW shells, at least there is some hope that a shell would strike something fragile or the sub would be damaged by the HE-shell explosion, even if the shells did not strike they at least would force the sub to be frightened and stay submerged so negating a possibility for the sub to attack me or the convoy - you see enemy, you shoot. The only unrealistic thing I see is the fact that they continue for far too long when you submerge while it should be no more than a minute or two in reality.

If only we could get of the friendly-fire issue... but it is not this mod's issue since if planes do not check for friendly-fire condition they can strafe a friendly DD on a DC run. That means that it is a stock AI error.
