Nice. I prepared full report for IRAI 0.19 and after it I see new IRAI version...
REPORT FROM TEST IRAI 0.19 / PEDESTAL MISSION
About zigzags:
I saw that at IRAI 0.19 all merchants in convoy do not zigzag at the same time and direction. I dont know that is good solution (in real the commander give order to zigzag, and all merchants in convoy turn left or right.
The problem is that the zigzag's angle is too small (for me).
SH3 and SH4 used 45° per zigzag. 20° is too small to avoid torpedoes.
About durability of conning tower:
I have situation when plane attck me by bomb and hit near command room (under conning tower). Result: hull of command room is 1%, conning tower: 100%... and flooding (sparkles, water) from conning tower.
About air attack on task force:
1. No reaction, convoy keep formation when planes are attacking.
Good! But what about zigzags if attacking plane has a torpedo?
2. Did you something with the AI plane code? At first I look 11 planes attacking Italian convoy at Pedestal... good!
3. At first all planes are attacking my uboat, after few air waves, they are attacking main target (Italian BB) and they do not attack me (ignoring me)... a special plane? Special target?
4. At some cases airplanes do not attack the target, if is at the visible range - something like point 3. It looks like the target must be "in front of" the plane... strange. Some of this group had course 1000m after last ship in convoy at no attack...
5. Some planes do not throw a bomb to the target, and try use it again and again...
About strange uboat speed:
It is strange (I'm boring, huh?), but when my batteries was not full and in "load battery" mode the maximum possible speed is 14kt and is impossible to order 12kt:
I precise 12kt at speed box, at the command/order box is 12kt (correct), but in speed box the summary speed is only 8 (motors not damaged).
About warship tactics:
1. Attack between battle groups
Italian group reacts when British DD was very close. BB do not used his long-range guns! They used it when the target was closer than 4500m...
2. Only 2 British DD change his course and attack enemy (circled).
Other groups (right DD pack, Italian and bottom British taskforce) do not react (long range guns at Littorio nad Nelson!).
Blue/red arrows: group courses. Only units in circles changed his course and attack. It looks like right red group is attacking blue, but in real these groups were passed.
Black arrow: I had contact with merchants - "send report" and no effect for Italian taskforce.
3. At first DD attack my sub by guns. No reaction from Italian taskforce.
4. This mission will be exciting if DD can shot torpedoes - I do not lose a hope...
Attack on main Pedestal convoy:
1. Only 2 closest DD from all 7 spotted attack my uboat. Good!
Unfortunately convoy without reaction (should escape or start zigzaging: long-range torpedoes, maybe wolfpack).
At second attack from second convoy's side only 1 DD reacts.
Convoy keep formation, course, speed (no min-max speed, no zigzags).
2. Surfaced at centre of convoy. No zigzags from merchants again.
3. Rest of DD: no activity (in my opinion they should looping to try find other boats / wolfpacks).
4. Again the DD in escort (only in main Pedestal convoy) have not passive sonar (no orange circles).
5. Moment... I have other merchant contacts... this is 1st part of Pedestal main convoy!!! Group keep formation! Very good!!!
But wait a moment... they are without escort!?
Attack on HK group / carrier taskforce:
1. Group keep formation!!! Yeahhh!
2. First reaction: escort start shooting to my uboat at range 5.5km (visible range on sensor map -dark grey circle- is 13.5km).
3. After submerging... no fast reaction from AI escort!
Two DD reacts, change direction to my submarine, but keep 5kt (group speed).
4. All task force (excluded attacking DD) change strong the course (escaping) - good!
5. Fantastic job, man! Fantastic job!!!!
Taskforce changing speed to 9-18kt, still escaping (keep my uboat at their stern and strong zigzaging!!!!)
Panic in the taskforce, collision CV-DD, DD sunk...
6. Attacking DD is in on my stern. Ready to attack... this DD has still 5kt (my speed 7 submerged). Other DD is closing. Correct attack. I'm sunk.
It looks like 1st give data to 2nd... or cannot attack faster than 5kt.
Probably group do not have a "escort leader" - sunk at mission start.
This is not a criticism of your work, but only the observation which elements do not work correctly.
Beta-tester.
