[TEC] Can we find a solution for ships circling around when convoy is attacked?
 

Well, devs have announced this in the upcoming 1.3 patch:
"The Group AI should always choose a new commander when the current one gets killed, instead of waiting for the currently assigned one and having all ships circle around".

This is the problem we all had when attacking convoys/TF...
Can we find the solution before the patch?

Group leader / Commander is set in the campaign files (.mis)
Example:

And this is how it looks in the .mis file:

…
[RndGroup 1]
GroupName=41a_Jap_TaskForce_001
Category=0
CommandEntry=0 :ping:
Long=16796400.000000

GameExitDate=19420228
GameExitTime=0

MaxUnitsCreated=100
DockedShip=false
NextWP=0


[RndGroup 1.RndUnit 1]
Class=BBIse

Origin=Japan
Side=0
CargoExt=-1
CargoInt=-1
CfgDate=19411201
No=2
Escort=false
SpawnProbability=100

By setting CommandEntry=0, RndGroup 1.RndUnit 1 is choosen as leader.
If only we could make it CommandEntry=0; CommandEntry=1; CommandEntry=2... :hmm:

Interesting.. Wonder if the game can read semicolon so that more command entry units could be assigned to that group... Have you tried it? I'm not sure if I understood it... You're saying that escort behavior could be related to this? Do you mean that the DD's are circling or all ships?

My biggest concern is the destroyers which just stops and doesn't do anything

It is related: 1.3 patch states that it SHOULD solve "The Group AI should always choose a new commander when the current one gets killed, instead of waiting for the currently assigned one and having all ships circle around".

I presume that means that every unit in the group follows the group leader (set as CommandEntry=xy). If the leader unit is sunk, disabled or slows to 1kts, all other ships (including escort destroyers...) will still follow him.

I have not (yet) tried to play with it... I'm waiting for some help from more experienced modders :|\\

Ok, i see... I'll try and post back soon! ;)

Since the groups will appear randomly it will probably take a lot of time testing this. I have modified all convoy groups and will try to play now to see if there is any difference!

Looks like Cargo ships usually are the group leader for 41 convoys file... So in order to test my changed file I'll have to try to sink one of the cargos... :hmm:

Ok!

Tested by adding these lines in all of the random groups for 41. campaign..

I met a convoy and closed for battle...

When hitting the first merchant everything seemed normal. after hitting another ship with my second torpedo, the game crashed to desktop.
I guess I must have hit the group leader.

Appearently the game didn't know how to read multiple command entry lines...

I'll try some more...

:know:

Tried this.
Still no luck. I got to play longer now. I saw that when hitting several ships the destroyers acted like they normally do. stop up and act passive... no change here..

If someone has some advice here, I might try - or I'll wait for the 1.3 patch with all the AI fixes! Really look forward to that...

What happens when you have multiple leaders..

ie

the first entry is 3 x GenericCargo

Leader set to "3 x GenericCargo"...

Then if you kill one, the others are "probably" "maybe" still leaders.. convoy continues..

Yeah I saw that comment and mulled it about today. I am not so sure about the fallen leader theory.

I have seen that kind of behavior practically every time. I target only one ship per approach, full spread. Seems too much of an unbelievable co-incidence that I pick the leader every time.

Not saying it has no effect, just that I think there is more to the story. FWIW. As usual when I'm in guess mode, I'm happy to be wrong.

Just wondering, what happens if the command entry is disabled thus: ;CommandEntry=0

Would that make a difference...I mean all captains respond to the threat??

Haven't tried that one. leaving for the weekend... I can test on monday, but if anyone else would like to try.. please post your findings here :up: Thanks

I agree, my experiences make me think you are right. Sure Leader death is a one big problem as I tested the other night in a scripted mission, sink leader = 3 knts sink another and leader alive = 7, 8 knots zig zag.

But I am sure I have hit non-leaders and seen bad AI.

:hmm:
Maybe leave it to the devs then...

could someone see how does CommandEntry= look in .mis files in SH3?
If it is the same as in SH4, I guess it's hard-coded...

P.S. Appreciate the effort, kakemann. :up:
