Hmm. Under which circumstances would one be able to influence another ship or it's crew that much? I thought about spying, but this thread here is going further.
It's all based on BCC. And that was probably based on ideas in older BB threads (2007-11) - see wiki page for links.

So I replaced Murgh's AI.plist with Littlebear's.

Littlebear's AI.plist is giving my AppleMac a major case of indigestion - and I've no idea as to what is up.

The AI.plist currently looks like this:

Code: Select all

{
    GLOBAL =     {
    ENTER = "setState: CLOSE_WITH_PLAYER";
                        };

"CLOSE_WITH_PLAYER" = {
	ENTER = ("scanForNearestShipWithRole: player")
	"TARGET_FOUND" = (setTargetToFoundTarget, setDestinationToTarget, "setDesiredRangeTo: 1000.0" checkCourseToDestination); 
	"COURSE_OK" = ("setSpeedFactorTo: 1.0", performFlyToRangeFromDestination);
	"WAYPOINT_SET" = ("setAITo: gotoWaypointAI.plist");
	"ATTACKED" = (setTargetToPrimaryAggressor, "setStateTo: ATTACK_SHIP");
	"ATTACKER_MISSED" = (setTargetToPrimaryAggressor, "setStateTo: ATTACK_SHIP");
	"INCOMING_MISSILE" = (fightOrFleeMissile, setTargetToFoundTarget, "setStateTo: ATTACK_SHIP");
	"DESIRED_RANGE_ACHIEVED" = (setState: MOVE_AWAY_FROM_PLAYER);
	"CASCADE_WEAPON_DETECTED" = ("setAITo: fleeQMineAI.plist");
	UPDATE = (performFlyToRangeFromDestination);
    };

"MOVE_AWAY_FROM_PLAYER" = {
	ENTER = ("scanForNearestShipWithRole: player")
	"TARGET_FOUND" = (setTargetToFoundTarget, setDestinationToTarget, "setDesiredRangeTo: 1000.0", checkCourseToDestination);
	"COURSE_OK" = ("setSpeedFactorTo: 1.0", performFlyToRangeFromDestination);
	"WAYPOINT_SET" = ("setAITo: gotoWaypointAI.plist");
	"ATTACKED" = (setTargetToPrimaryAggressor, "setStateTo: ATTACK_SHIP");
	"ATTACKER_MISSED" = (setTargetToPrimaryAggressor, "setStateTo: ATTACK_SHIP");
	"INCOMING_MISSILE" = (fightOrFleeMissile, setTargetToFoundTarget, "setStateTo: ATTACK_SHIP");
	"DESIRED_RANGE_ACHIEVED" = (setState: CLOSE_WITH_PLAYER);
	"CASCADE_WEAPON_DETECTED" = ("setAITo: fleeQMineAI.plist");
	UPDATE = (performFlyToRangeFromDestination);
    };


"ATTACK_SHIP" = {
	ENTER = (setTargetToPrimaryAggressor, performAttack);
	"FRIENDLY_FIRE" = ("setStateTo: BREAK_OFF");
	"ATTACKED" = (setTargetToPrimaryAggressor, performAttack);
	"INCOMING_MISSILE" = (fightOrFleeMissile, setTargetToFoundTarget, performAttack);
	"CASCADE_WEAPON_DETECTED" = ("setAITo: fleeQMineAI.plist");
	"TARGET_DESTROYED" = (performIdle, "setStateTo: DECIDE_ROUTE");
	"TARGET_LOST" = (performIdle, "setStateTo: DECIDE_ROUTE");
	"NO_TARGET" = (performIdle, "setStateTo: DECIDE_ROUTE");
	"CASCADE_WEAPON_DETECTED" = ("setAITo: fleeQMineAI.plist");
	"FRUSTRATED" = (performAttack);
    };
}
"Atom" flags up the following as problematic

"TARGET_FOUND" = (setTargetToFoundTarget, setDestinationToTarget, "setDesiredRangeTo: 1000.0" checkCourseToDestination);

- and my AppleMac parser says "Old-style plist parser: missing semicolon in dictionary"

"DESIRED_RANGE_ACHIEVED" = (setState: MOVE_AWAY_FROM_PLAYER);

"TARGET_FOUND" = (setTargetToFoundTarget, setDestinationToTarget, "setDesiredRangeTo: 1000.0", checkCourseToDestination);

"DESIRED_RANGE_ACHIEVED" = (setState: CLOSE_WITH_PLAYER);


I have no idea as to where a semi-colon should go... nor have I any idea about the other issue

You're not looking for a missing semi-colon; you're looking for a missing comma. The semi-colon is an end-of-line marker; when parsing fails, the error message assumes you finished one line and began another line, forgetting the semi-colon. But that's just the error message, based on it being a common error back in the olden days.

You're missing a comma, between the third and fourth instructions.

"TARGET_FOUND" = (setTargetToFoundTarget, setDestinationToTarget, "setDesiredRangeTo: 1000.0" RIGHT ABOUT HERE checkCourseToDestination);

No, wait, I see it now: the first line in CLOSE WITH PLAYER is missing its semi-colon (at line end), and the second line is missing a comma. I'd still bet a dollar both errors get the same "semi-colon" message, though.

Global should also be:

ENTER = "setStateTo: CLOSE_WITH_PLAYER";

rather than ENTER = "setState: CLOSE_WITH_PLAYER";

To debug, look at the log and search for the name of your OXP. If there is a fault it will log the line number where it could not phase the file.

Same typo of setState rather than setStateTo under desired range achieved.

They're strings with whitespace; they crave chicken scratches.

"DESIRED_RANGE_ACHIEVED" = (setStateTo: CLOSE_WITH_PLAYER);

Should be:

"DESIRED_RANGE_ACHIEVED" = ( "setStateTo: CLOSE_WITH_PLAYER" );

Thanking thee!

According to my AppleMac parser, that fixes it!

Now to see if it does what it is supposed to!

And it doesn't!

Bumped into a clutch of Refugee Adders (what is the collective noun for them?) at Bemaera - and they were just tumbling and not going anywhere. Even when I flew into the middle of them and had a "BCC" natter with a couple of them. They did not follow me when I left, and just carried on tumbling.

I'm sorry about doing this. But I don't understand what I'm doing, what the code does, how it works, etc.

I did sneak a peek at the AI.plist wiki page, but the way it starts (The AI system consists of a stack of state machines (only the top one of which is active), which respond to game events sent to them as messages. They respond by calling a series of methods which affect the behaviour of the Entity and possibly trigger changes to the AI by changing the state or (more drastically) the state machine.) is just so much gobbledegook to this dumb pilot.

"stack of state machines" (the links on the page do help, but I don't really understand - I've no context for any of this - so, what other "machines" are there other than "state machines"? Can they be arranged in a form other than a stack?)

What are these "messages"? Where do they come from? Where do they go to?

What is the behaviour of the Entity supposed to be?

What is the difference between changing the state and changing the state machine?

And I'm not sure that understanding what it really means would help fix my problem anyway...

Yeah, that is the follow player AI, right? But what AI do the refugee ships have? If the refugee ships have this new AI, how did/does that come to be? Tell us all the details you're omitting.

Sorry - I was busily adding more oomph into my whine above.

I overwrote the original refugee ship AI (it is printed above and again, below) since I know of no way to transition from the one AI to the other AI and wished to test the fruits of Littlebear's labours.

I overwrote the original refugee ship AI (it is also printed above) since I know of no way to transition from the one AI to the other AI and wished to test the fruits of Littlebear's labours.
So, you just have zombie ships floating there, with no active AI?

Now, we discussed this last week.

1. You put LittleBear's AI into a file called FollowPlayerAI.plist
2. You find the native Oolite function to change AI by researching on the wiki.
3. You target a ship, go to the debug console, and type PS.target.whateverThatFunctionWasCalled("FollowPlayerAI.plist")
4. Then you come back here and whinge at LittleBear.

And don't forget the chicken scratches. " " " " " " " "

I think the AI is working, even though they are just hanging there. The trouble is they were only told to scan for the player once under ENTER. So they did this as soon as they spawned (when you weren't there) and then never scanned again (when you were!). So whilst they have gone zombie, it's not (as it usually is) a sign of a broken AI. The AI isn't telling them to do anything after scanning once under enter, so they never get a TARGET_FOUND as they ain't looking (as we didn't tell em to).

Need to change the UPDATE in the look for player state to:

UPDATE = ("scanForNearestShipWithRole: player", performFlyToRangeFromDestination);

Then they'll keep looking for you until they find you.

It might be simpler to just have one AI. IE take Murgh's orginal (save it as a differently named .plist) and set that as the ship's AI in shipdata. You can then just add a "scanForNearestShipWithRole: player", to Update in every one of the original states and a TARGET FOUND to either switch AI's (or you can just switch states and C&P the find player AI into the new version of Murgh's.

The example below, from the rebooted assassins, tells the ship to hang around near its mother station until the player arrives and the switch AIs on a dice roll when it finds them. You can switch AIs as shown in the example under FOUND_PLAYER.

Messages are sent by the ships script, so the AI can react to particular events. In the example the "FRIENDLY_FIRE" is a custom script message. If the ship is accidently hit by a ship on its own side, rather than attacking it it's AI recieves the message "FRIENDLY_FIRE" instead of ATTACKED.

This allows you to (if you need to) use IF X then do Y in the AI. You make the condition check in the script and if the condition is true then it sends an AI message to the ship, which the ship's AI reacts to. The script on the mafia-ship script tests the role of attackers and disregards accidental hits by it's own side. Script is below as an EG of how you can send script messages to the AI. In this example, the accidental attacker also gets a TARGET_LOST message if it hits one of its own side, so it will stop firing as soon as the first laser bolt hits the wrong ship. This stops carriers with big turret batteries accidently blowing their own fighters to bits whilst aiming at an enemy. As soon as the first plasma bolt hits a friendly ship, the carrier will stop firing and look for a new target. The ship hit by the plasma bolts also gets a AVOID_LAWFUL_GUNNER message. The mafia ship doesn't use this (as none of the mafia ship fleet have turrets). But for ships which have turret gunners on their side, they get switch to a state which tells them to move 3kms from the position they were in when they got hit, so they don't get hit again when the turret gunners start fireing again.

I've modified the AI to see if it works and will give it a try. Parser has given me the thumbs up.

Thanking you, gentlemen.




But what I want to achieve is to have the switch in AI made as a response to the BCC. Which presumably requires different coding.

Either have the Refugee Adder randomly ask the player: "Can you escort us to the station?" or else have the player offer and the Refugee Adder randomly accept.

And then I suppose that it would be an idea for the player to offer to open a witch-hole to somewhere safer as a system, too. Presumably once the Refugee Adder has accepted the player as an escort, it will follow the player into the witch-hole anyway.




If I can manage something workable for all this then I can see the following loose ends looming in the distance.

1) Some sort of future tie-in involving refugees wishing to thank the player. (Relevant code in Illegal Goods Tweak OXP)
2) Possible issues in eg. Corporate States, involving the player being sued for aiding and abetting illegal immigration (Relevant code in Illegal Goods Tweak OXP)
3) What about enabling various strategies if the party is attacked by pirates/Thargoids etc? Ranging from "Flee! I'll hold them off!" to "Stay here while I get him!" to "I'll be dropping a cascade mine shortly - you flee and I'll loiter with intent!" to "Meet you at the main orbital station" to "Are you any good with that gun of yours?"

Don't do that. I've told you how to proceed: make sure the AI is doing what you want (not something vaguely like want you want) before you start on the javascript. Then get a working script before you start dreaming of feature creep. You want this piece of the puzzle definitively finished, and crossed off the to-do list.

With Nick's clearly written instructions (which I'm sure they are - I haven't read them yet), writing a plug-in for BCC will be a doddle, if you stop day-dreaming. :D

That you don't need to worry about. I am trying to nail the AI down first. But I'm also trying to understand what I'm doing (at least a little). Currently rereading the AI pages and trying to make sense of both them and the AI.plists given above. And am very slowly getting somewhere!
