Hi all,
I need a trader AI but for a ship which avoids combat at all costs. Below is a blend of route1traderAI and traderinterceptAI which I hope will do this, but I do sometimes get bogged down with AIs.
If anyone would be kind enough to look this over for me, I'd be really grateful.

Code: Select all

{
	GLOBAL = 
	{
		ENTER = ("setStateTo: HEAD_FOR_PLANET"); 
	}; 
	"HEAD_FOR_PLANET" = 
	{

Under Flee section you have:
DEPLOYING_ESCORTS = (setTargetToPrimaryAggressor, "setStateTo: FLEE_WITH_ESCORTS");

...Yet I don't see anything else that uses the FLEE_WITH_ESCORTS messageString. Is that used in an external script? (...maybe for the escorts?)

You might want to increase the flee distances from 25600 to 26000-30000, in case of a half-hearted chaser.
"setSpeedFactorTo: 9.0" could also be added to flee using injectors.

Hi Switek,
Thanks for having a look. I actually meant to remove the 'flee with escorts' part as there are no escorts. Presumably I can just remove the whole section

Code: Select all

 DEPLOYING_ESCORTS = (setTargetToPrimaryAggressor, "setStateTo: FLEE_WITH_ESCORTS");

Your suggestions are also good, so the revised AI looks like this

Code: Select all

{
	GLOBAL = 
	{
		ENTER = ("setStateTo: HEAD_FOR_PLANET"); 
	}; 
	"HEAD_FOR_PLANET" =

		"UPDATE" = (setTargetToPrimaryAggressor, fightOrFleeMissile, "setStateTo: FLEE_FOR_MISSILE"); 
	}; 
}

I'm never sure if I need the quote marks (") for things like the "setSpeedFactorTo: 9.0"? I'm assuming I do.
Cheers,
Smivs.

I made it two separate AIs so the traderInterceptAI could return to the state that called it. When you merge them to one single AI, you should decide what something like:

Code: Select all

"XXXXX" = (exitAI);

Must do. There is nothing to exit now.

Hi Eric,
I said I don't understand these too well!
I thought by taking the 'Flee' element from traderintercept and incorporating it into route1trader I could make a single AI that would get my ship from witchpoint to planet while avoiding combat/conflict, and that it would 'Exit' when it switched to the docking AI.
I notice that I have two "ExitAI" commands in the Flee and Fleeformissile sections, which are probably not helpful, as I presume it currently has nowhere to 'exit' to...is that what you meant.
So if I keep the single AI, does it still need to 'Exit' at some point?
This is the current attempt.

Under Flee again...is the 10 second pause here:
FLEEING = (setTargetToPrimaryAggressor, "setStateTo: FLEE", "pauseAI: 10");

...meant to prevent a conflict or just to be a very slow reaction?

Commander Smivs · Post by **Smivs** » Wed Dec 15, 2010 10:35 pm

I've got no idea where that came from, and I hadn't noticed it. Thanks. I'll remove it.
