I've found out the hard way with convoys heading to near the planet, those ships head to different points AROUND the planet rather than to the same point.

This could be solved, however, by setting a destination in their ship script rather than in the AI.

How many ships can a station hold anyway?

In Oolite's game engine, strictly speaking, only one (the player). An unlimited number of ships can be removed from the universe by docking, or added to the universe by launching, provided that doing so does not breach the overall entity limit, but the station doesn't have a concept of "docked ships". Most of the launch routines do track how many ships of that type the station has launched since it was generated, up to an internal limit, but the ships launched by those routines don't meaningfully exist before their launch is requested.

In terms of internal volume, a basic Coriolis station is slightly less than a cubic kilometre in size. Obviously you can hold more orbital shuttles than Anacondas, and there presumably needs to be some room on the station for things which are not docked ships, but several hundred at least. (The original Elite manual claims 2000, which is possible with plenty of room to spare if most of them are small in-system craft, but seems a little on the high side)

I spotted a Viper *WAY* outside the usual spacelanes...and bound for nowhere in a real hurry! It was heading almost directly away from the planet along the z-axis. There were no ships near it. The only reason why I found it was because I'm using Okti's Long Range Scanner OXP.

Entry about the Viper in Latest.log:

01:55:43.484 [universe.objectDump]: Ent: 1 ShipEntity "GalCop Viper Interceptor" position: (-128870, 2450.71, 1.56383e+006) scanClass: CLASS_POLICE status: STATUS_IN_FLIGHT range: 702.462 (visible: yes) mass 43245.4 AI: interceptAI.plist:ATTACK_SHIP

How it got into that state is a mystery.

Adding this:
"NO_TARGET" = (performIdle, switchLightsOff, exitAI);
to interceptAI.plist, ATTACK_SHIP section ...might help it break off from its "attack".

While I'm using Switeck's Shipping OXP, interceptAI.plist is not modified by my changes.
I'm using windows version of Oolite v1.76.1, along with Win XP Pro SP3.

It would be interesting to know whether there was any other ship nearby. Vipers chasing offenders away from the space lanes are quite common. I have occasionally come across a pairing of pirate and police ship way out in deep space. As long as the Viper doesn't manage to kill the pirate, this chase is pretty much going to go on forever. There is no such thing as BREAK_UP_WHATEVER_YOU_ARE_DOING_AND_RETURN_TO_THE_PLANET_BECAUSE_YOU_ARE_TOO_FAR_IN_DEEP_SPACE in any AI.

Thus the really useful thing to test would have been for its target. So, once you could target the Viper you should have typed in the JS-console.

If the Viper's target was indeed nowhere near, it would be interesting to know why it never received a TARGET_LOST (that's the relevant AI message here, not so much NO_TARGET). It should not chase a target that has a higher speed (and therefore gains more and more distance) forever, but break up the chase as soon as it's clear that the target can't be overtaken. So, if the target was really totally out of reach, this mighty be another reincarnation of the still-targeting-targets-that-are-way-out-of-scanner-range-bug.

There was nothing within about 1500 km from it. I used LongRangeScanner OXP to find it while I was far, far away from it...and teleport my ship there. The Viper was heading away from the planet, stuck in interceptAI.plist:ATTACK_SHIP mode. There was nothing in front of it, so it would continue that way forever.

Found another, this time it was a Mamba escort:

Once again, NOTHING around this Mamba ship. I "teleported" to it only moments earlier, so my ship shouldn't be to blame for its location.

I found another ship doing the same thing, a Cobra 1:

While I may have ran the game at TAF 16x speed for awhile, shouldn't the npc ships course-correct sometime after lowering TAF back to 1x?

These ships weren't "dead", they reacted quite quickly when I shot them...and after I cloaked they headed towards the planet though they're still a LONG ways off.

I had to "abbreviate" my Latest.log to post it here:
http://pastebin.com/qXxh9hHi
I deleted many duplicates of this:
[swi-oolite-constrictor-hunt]: checking conditions... Constrictor Hunt Mission: null GalaxyNumber: 2

...I almost forgot, I also scooped a cargo canister that didn't make a sound and didn't give me anything. It didn't even register as scoopable cargo to LongRangeScanner v0.311.oxp!

Hmm... I've noticed situations where ships were in a continuous waypoint AI loop as they were just getting COURSE_OK messages in GO_TO_WAYPOINT. No idea why FRUSTRATED or DESIRED_RANGE_ACHIEVED was not being fired.

I wonder if I should ram them (triggering damage check?) or at least get in their way (pathfinding check?) the next time I see ships wandering off to deep space...

Actually I find that does work. Although I don't ram them I just creep up on them until the collision detection kicks in which wakes somebody up on the bridge.

For the record, if a ship has a primary target it’s included in the dump after “Behaviour:”.

I thought as much because of this in Switeck's third entity dump:

This means, however, that the first two examples are indeed stuck in the ATTACK_SHIP state of interceptAI without having primary targets, which shouldn't happen.

So there seems to be a bug somewhere indeed. Can be OXP-induced as well, of course.

Spacer sickness - spend long enough in the black and you'll melt into it.

I'm also seeing Thargons which my lasers often pass through and even ramming them doesn't work...they're at least sometimes "ghosts"!

I re-ran tests with Oolite development version 1.77.0.5403 ...and got the same results concerning npc ships wandering off into deep space stuck in interceptAI.plist, ATTACK_SHIP, Target: <none>

Latest.log from that posted here:
http://pastie.org/4929329

I had to cut out all the:
12:36:03.718 [swi-oolite-constrictor-hunt]: checking conditions... Constrictor Hunt Mission: null GalaxyNumber: 0
and OpenGL extensions list to get that paste down to <64 KB.

Can I ask an obvious question:

Do you see those ships stuck in interceptAI without having targets when you de-install your OXP?

No I hadn't bothered to. But since you insist...

This happened without my Ai-modifying Switeck's Shipping OXP installed:

It was heading the wrong way to go to any reasonable waypoint. Basically booking it to get as far from the sun and planet as it could get till I shot it to get its attention...then fled off radar, cloaked, and went back to it to see what it'd do. By then, it had turned around and started heading towards the planet...best I could tell.

Testing without my Switeck's Shipping OXP isn't the same as testing with an OXP-free game.
I have other OXPs installed, some of which are necessary to do these tests. It's ultimately too hard to find ships at these distances without help. Sure, Pause + 0 key and reading Latest.log can tell me they're out there, but not well enough that I can discern their heading and probable destination. I have to get in close to mark-1 eyeball them to do that.
