1.72.2 Linux - managed to target myself

[Smeghead]

I poked around in the search, but I didn't manage to find anything that matches this weird bug. Apologies if this has already been reported.

Anyway, I've managed to get oolite into a state where I've targeted myself, and I can take damage by shooting myself. Yes, I am possibly that retarded.

Allow me to back up a bit...

I'm running with a variety of expansions, including the Galactic Navy oxp. While on the way to a naval reserve mission (to intercept a Thargoid fleet, natch) I misjumped and ended up fighting off a bunch of Thargorns. You know how it goes - kill all the heavies, and you're left with a bunch of deactivated fighters floating about the place.

To pick up a few extra credits & kills on the cheap, I typically destroy a few of the fighters before jumping on. I was in the middle of doing just that when I encountered something really weird.

After blowing a few of 'em away, I put another fighter in my crosshairs and targeted it, only to be told "Ident System locked onto Cobra Mk III". That looked a bit odd, I thought, but on the off chance I was inadvertently targeting another ship, I veered off and approached from a different angle.

Retargeting resulted in the exact same message. Even weirder.

Seeing nothing that I would hit inadvertently between me and what I thought was my target, I went ahead and fired. To my surprise, my fore shields took a hit.

I thought I'd screwed up at that point and managed to hit someone else, causing them to retaliate, or there was something else out there firing on me. However, the HUD was still showing condition yellow, I'm Clean, and there's nothing on the scanner that would likely be hitting me from the front.

Not understanding where the shot came from, I fired again. My shields dropped even further. I fired again, and got the same effect.

I believe I've gone and targeted myself, or more properly, I've targeted another object out there that appears to somehow be a clone of myself. It has the model of a Thargorn fighter, but apparently is my doppelganger.

Here's a Shift+h dump of my target:

I've suspended this instance of oolite for now in case anyone would like me to dump more information to the log.

I have heard this one time earlier, about half a year ago. In your dump there is another strange thing. It has a proximity alert with itself. No idea though what is happening here.

[Nemoricus]

I've had this happen to me once or twice before. The targeting bug is not something that Galactic Navy does. It' a problem somewhere in Oolite itself.

It's still very strange and annoying, though.

I think that the thargon may have aqquired ID 100, when/if the ID wraps...
since there are special circumstance in regard to the thargon.. & ID 100 is always the player,

1 it is launched like a missile. (therefore it spawns in a special way)
2 it becomes uncontrolled

somewhere in the code maze it may aqquire ID 100, but not very often / or often enough for the player to take notice...

[Smeghead]

The proximity alert probably isn't that weird, given the circumstances. It's me (or at least, its metadata is), it has the same position as me (even if the model doesn't), so it's basically always going to have a proximity alert.

Heh - I wonder if, during the fight, I took hits from everyone else shooting at it. Also, I'm somewhat tempted to try to scoop the little bugger, just to see what happens.

This kinda makes me want to check out trunk and have a poke around to see what makes all this stuff tick.

Anyway, I'm assuming that there's probably nothing more to be gleaned from the current state of the program, given it already acquired the player's ID a while back.

Edit: heh - it's unscoopable. The fuel scoop's trying (HUD animation, sound effect), but the little sod ain't moving, which shouldn't be that surprising, I guess.

I guess herein lies a clue to tracking down and fixing this bug.. gotta hand it to you Frame.. you're good at finding these things..
