HUNTER: These ships cruse the space lanes and attack offenders and ships with bounties (including the player of cause). They are pretty brave in combat only fleeing if really badly hurt and sometimes fight to the death.....

Can someone satisfy my curiosity?......Yet when you look at the Hunters from the core ships they seem to use either the Route1trader.AI or the Pirate.AI, which are clearly very different. So what gives the Hunter (or any other Role) its particular behaviour pattern?

Ah, that makes sense.
So say a Hunter/Trader with a trader AI specified in the shipdata.plist would switch to, what, a Police AI if it was spawned as a Hunter?

Escort ai changes escorts with a bounty to pirates (if they have a cargo bay) because they are automatically ejected from being an escort of a clean mothership.

Locates all the ships in range, multiplies the legal status with a government factor, subtracts a random value between 0 and 255 from this result and compares the remaining value. It chooses the worst remaining offender. Because of the random value not all ships are found in every scan and the lower the bounty and lower the government, the longer it takes to detect a ship as offender. Returns: "TARGET_FOUND" or "NOTHING_FOUND".

Government factor = 0 in an anarchy and increases with 0.4 for every government till it reaches 2.8 for a corporate state. Result is that it never finds a ship in an anarchy, that is needs 637 points to always find an offender in a feudal state and only needs 91 points to always find a offender in a corporate state.

scanForNearestShipWithPrimaryRole:(NSString*) role

scanForNearestShipWithPrimaryRole:pirate,

[ai.unpermittedMethod]: Handler "UPDATE" for state "HEAD_FOR_WITCHPOINT" in AI "cbhAI.plist" uses "scanForNearestShipWithPrimaryRole:pirate", which is not a permitted AI method.

If I understand this correctly it means that a scan for offenders will never find an offender in an Anarchy, and is unlikely to in a feudal state as well. Now as this is where you'd most expect to find offenders this struck me as odd. Is this right? Perhaps it's to stop any Police/Hunters cleaning up the System before you (the player) arrive.

I tried

Code: Select all

scanForNearestShipWithPrimaryRole:pirate

with upper and lower case Ps on the pirate, a space and no space after the colon and pretty much every other permutation, and it gets rejected.

scanForNearestShipWithPrimaryRole: pirate

ENTER = ("scanForNearestShipWithPrimaryRole: buoyForCollisionTesting", "setSpeedFactorTo: 1");

Thanks for that Eric. Unfortunately it's still not working. I've tried :-

UPDATE = (setCourseToPlanet, "setDesiredRangeTo: 50000.0", checkCourseToDestination, scanForOffenders, scanForHostiles, scanForNearestShipWithPrimaryRole: pirate, "pauseAI: 10.0");
	};
