Clean-attacking System Vessels

Post by Lestradae »

Since 1.72.1, I started encountering system vessels that suddenly started to blink red-violet and then proceeded to attack me.

As this happened with a lot of diverse vessels, I assume it's not an oxp thing. They fire at me even if I'm clean, and if I return fire I go fugitive immediately.

Has someone else encountered this? Is it a known bug?

Also, when I shot down one of the system vessel attackers (an RS Imperial Courier-Corvette) it released a "Pitau something" from Simon's ship oxps as escape pod.

There is no reason why an RS Imperial Courier system vessel should go on a rampage, and why does it have a Simon ship as escape pod?

I have never experienced this. Next time it happens, please target the vessel that attacks you, press Shift+H, then post the log here. We may be able to figure out something.

Gotcha

So, got it a second time, a Dragon Assault Craft this time, did the Shift-H thing and here we go:

What do you expect with a pirate (dragonpirate) AI? Smells like a oxp mistake...

Wait a moment. I think I have it. It says "State machine name: dragonpirateAI.plist". I went & had a look.

The Imperial Courier Corvette and the Dragon Assault Craft are both police that have been like_ship'ped from something that has a pirateAI.

I assumed that if the game chooses something with the role of police, wingman or interceptor that had the scan class police it would automatically use the usual policeAI ... am I mistaken? Then there would be a whole class of new problem, which I never experienced before?!

Did something change in 1.72.1 concerning the AI's chosen or did no one including me notice this bug-possibility in RS yet?

Automatism has always weak points and I don't understand why scripters don't assign roles, AIs or shipScripts for every entity. This is probably the only way to get rid of unwanted behaviour.

EDIT: I think like_ship is a very complex thing, so we better should declare the important keys directly and not via like_ship.

Oolite does this automatic, but this ship is not a police, it has a primary role of military:

Code: Select all

[dumpState.shipEntity]: Primary role: military 
[dumpState.shipEntity]: Behaviour: BEHAVIOUR_RUNNING_DEFENSE 
[dumpState.shipEntity]: Target: <PlayerEntity> 
[dumpState.ai]: State machine name: dragonpirateAI.plist 
[dumpState.ai]: Current state: ATTACK_SHIP 
And military is not a role supported by oolite, but only by oxp.

Because I'm juggling an armada of ships here and was relying on this working as I supposed it would - give it the role police/wm/ic and the scan class police, it gets assigned the AI for police.

If I'm mistaken and it doesn't work like that, I have to change it, but then it's strange that to the best of my knowledge this didn't happen before 1.72.1.

For OSE, I'm nearly doing as you suggest - some ships get role-specific AI scripts, especially the future police and navy ships - but for example, future pirates, miners, traders or scavengers should better take their AI from the game, aren't they supposed to do that?!

Please note that this is not about blaming anybody, I just want to know how it works and if I made a mistake in my assumptions about that or if this is a core game bug, because which it is has a massive impact on fixing this.

Which would completely defeat the entire purpose of is_template and like_ship, the which I'm going to use extensively for OSE :wink:

Hope one of the Devs can help clarify this AI-choice topic for me,

That's it

Hi Eric Walch,

Thanks very much, that's it! Due to your hint with the military role I know now what the problem is, and also why it started to appear just recently!

The good news is, this is not going to happen in anyone's game but only my OSE beta, and is easy to be weeded out!

The even better news is, that it does work fine for normal police etc. then.

This is happening because I am creating a role for the military, which are called by a navypatrols script and placed into systems. The already newly integrated ships with this new role have a MilitaryAI of their own LittleBear nicely offered to me, but the old RS ships that I have not yet given a work-over, some of them have the role "military" also and so are getting spawned too, but they have no fitting AI (yet) and so the game takes their primary AI stated in their shipdata instead, and if that primary AI is a pirate one, that leads to erratic behaviour!

Thanks, guys, that was great help and I'm off to squash another, new, shiny bug :)

Cheers

like_ship in versions until 1.72 always made the change on the master definition and not an intermediate like_ship. When you keep that in mind like_ship works well.

In 1.72 this should have been corrected and you can also make chances on an other like_ship. This is better behaviour but when your OSE code it also used on older oolite versions you better stick to only redefining the original definition. Otherwise like_ship on like_ship will behave different with older oolites.

Because of exactly those issues and also because the new is_template command only works properly from 1.72.1 onwards, the future OSE's will require Oolite version 1.72.1 or higher to be playable. I already inserted a requires.plist into the beta to be sure for that reason.

I really need the new options of is_template and multiple like_ship'ing for where I'm taking the RS successor, and don't see the need to keep it compatible for older Oolite versions. One of these days we'll have the MNSR anyways :wink:

Thanks for reminding me and clarifying that multiple like_ship'ings only work from 1.72 onwards - I already knew about the is_template command, but not this one. One more reason to go 1.72.1.

Cheers
