Galcop Military Intelligence wrote:Urgent Notification to Civilian Commanders
Recent military intelligence and combat encounters have identified a new and potentially worrying evolution in Thargoid technology It appears that the recent appearance of space-borne "wasp-like" creatures within Galcop space (see the report by K. Wolf et al - Galcop Science Network #359-1701) has not gone unnoticed by our alien adversaries, who have also seemingly encountered them and their hive "stations".
As a result of this, a new type of Thargoid combat craft has now been sighted which has been nicknamed the Swarmer. Similar in design to their familiar octagonal motherships, these new vessels are distinguished byexternal protrusions used to carry small drone craft. These secondary vehicles seem to have replaced the conventional "Thargon" robot fighters, but if anything are more of a threat. Whilst they appear slightly weaker in individual weapon power, they are far more numerous with reports of up to 16 being released by a single mother vessel. But the most worrying aspect is that the craft appear to have taken the wasp swarming mentality, with co-ordinated attacks on individual vessels within a target fleet being reported.
One notable encounter with three of the mother vessels took all of the skill, bravery and cutting edge military technology of an entire wing of specialised Raptor anti-Thargoid destroyers to counter and repulse. Sadly this was not without losses of several of our brave heroes, leading to the decision to issue this wideband warning to civilian ships.
The increased numbers of the drone craft combined with their small size and faster speed has led to this new type of mother vessel being classification as an extreme threat to civilian and all but the most powerful of Galcop craft. We strongly suggest that discretion is the better part of valour in case of an encounter, and a wise Commander should consider using his fuel injectors rather than his weaponry to survive. However if combat is undertaken, notification to the local Galcop Intelligence directorate at the system main station should be made to assist in countering this terrible new threat.

Based on a chat with ClymAngus during the recent meet-up (the kind of thing that should probably be banned under the Geneva Convention), I would like to introduce a new concept variation of the Thargoid mothership and Thargons.
These are somewhat tougher than their vanilla bretheren, in that they swam attack rather than just work individually. When the motherships hunt in packs, they should be a challenge for even the most hardened battle veteran.
Note that currently under the current 1.76 trunk code, there is a minor issue with a ship script event (see here for details) which means that the Thargons are currently defined with a missile scan class. This means that they can trigger certain OXPs into trying to ECM them (amongst other things). The fix for this glitch should be in 1.76.1 when it is released, at which point the OXP will also be updated.

My log fills up with this now:
Exception: TypeError: this.ship.subEntities is null
Active script: swarm_thargoid 1.00
swarm_thargoid.js, line 45:
if(this.ship.subEntities.length === 0) { return; } // if we've run out of sub-ents before we run out of missiles
This may have something to do with huge hordes of "missiles" fired at my ship at once?

Hmm, that's a new one - that bit of the code hasn't changed at all since the first version of the OXP that was out for testing. And I would have thought it should perhaps always exist if the ship is valid, but I can work around that - I think the problem is not the lack of subEntities when the error happens, but more likely the ship itself has ceased to exist at that point.
The "missiles" are the thargons, as mentioned in the readme (and in the post above). I can't work around that until 1.76.1 (or trunk once Kaks' fix goes into the daily).
OK - v1.01 uploaded which should fix that, plus another small error in the script that I noticed whilst making the modification.

That looks kind of scary. Impressive, but scary.

Somewhat by design, and also by reputation

For whatever reason, the main ships sometimes have bounties of <10 credits.
They are also getting placed/displaced by "something" so far from my ship that LongRangeScanner OXP reports their distance as NaN!

Hmm, odd on both cases.
The bounty is set as 100 in the shipdata (same as the core ships), and it's all dealt with by the trunk code.
And equally there is displacement code on the ship, but only a short distance when they get energy low.
I would have to wonder if you've got another OXP installed that's screwing around with them?

When I edited the "ATTACK_SHIP" =
section of swarm_thargoidAI.plist from this:
ENTER = ("sendScriptMessage: startWeave", "sendScriptMessage: validateTarget");
EXIT = ("sendScriptMessage: stopWeave");
to this:
ENTER = ("sendScriptMessage: validateTarget");
...I no longer saw them getting displaced to "NaN" distances.
log(this.xOffset,this.yOffset,this.ship.position);
at a strategic point in swarm_thargoid.js just after this line 211
Code: Select all
this.ship.position = this.ship.position.add([this.xOffset, this.yOffset, 0]);
...dumped this strange data to log:

For whatever the reason, this.xOffset and this.yOffset seems to have undefined/NaN values at the time of the check. I do not know why, but I don't think OXPs are to blame.

That could certainly be the problem (it's not an external OXP thing you are correct), although I can't reproduce it. If I add similar logging:
Code: Select all
this.startWeave = function()
{
if(this.callbackID) { return; }
this.weaveTime = clock.absoluteSeconds;
this.phase = Math.random() * 2 * Math.PI;
this.callbackID = addFrameCallback(this.performWeave.bind(this));
};
this.performWeave = function()
{
if(!this.ship.isValid || this.ship.AIState !== "ATTACK_SHIP")
{
this.stopWeave();
return;
}
this.xOffset = (this.ship.speed/this.ship.maxSpeed) * this.weaveX * Math.sin(clock.absoluteSeconds - this.weaveTime);
this.yOffset = (this.ship.speed/this.ship.maxSpeed) * this.weaveY * Math.sin(this.phase + clock.absoluteSeconds - this.weaveTime);
log(this.name, "xOff = " + this.xOffset + " yOff = " + this.yOffset);
this.ship.position = this.ship.position.add([this.xOffset, this.yOffset, 0]);
};
I get the following:

And so on, which is more or less what I expect to see. I tried five or six different spawnings, and they all did that - no NaN's. Indeed from the definition of the functions (in the code at the top) I can't see how you're getting a NaN at all?
I wonder perhaps if this is showing up something a little more fundamental? What OS are you running? It can be got-around by removing the weaving (basically the modification you made, plus removing the then-redundant code) but I'd like to understand why there is this difference in the first place between your results and mine.[/color]

I'm on Win XP Pro SP3.
I'm getting these results by repeatedly misjumping between 2 systems. It (NaN errors) doesn't happen every time, but happens too much to be coincidence.

Just tried doing the same for about 10 minutes, and still can't reproduce the NaN's at all (with the roles tweaked so almost all I'm getting is swarm thargoids, plus targets via Behemoth Spacewar). The only things I see in the log are

That's using the normal max-pitch method of ending up in interstellar space.
I'm not sure what to do for the best here - to leave things as-are, to put in a .isNaN check on the offsets and if so just replace them with a random number or to remove the weaving functionality completely. It seems to be your specific example of doing unusual stuff in interstellar space that is influencing things. I'm on similar kit (Win7 64-bit + 1.76 release) so it shouldn't be anything to do with the trunk code itself I would say.[/color]

I'm using Oolite v1.76 -- I haven't updated to the latest trunk version yet.
