Odd behavior of laser-only crafts
« on: September 01, 2015, 11:05:10 pm »
v2.5

Before I submit a bug report, I'd like to know if the following behavior was experienced by somebody else.

Description:
It seems that in some conditions (relative speed, relative headings, coordinates on the Geoscape, laser gun only... ?) PHALANX aircraft won't close the UFO enough to fire at it, whereas it should have been a pretty straight case.

Reproducibility:
So far, it occurred only once, and that was with a slow and clumsy UFO: the Supply ship (this IS why a bug is suspected).

I first sent a 3 laser-Stiletto, thinking it was an easy job. As you can see on first screenshot, once it had closed the sluggish UFO, the Stiletto turned and preceded the UFO along its route, at the same speed. Thus, the Stiletto never came at range.
Seeing this, I sent a 1 laser-Firebird from the nearest base, and a 2 laser-Sarrasin from old China.
On second screenshot you can see that the three crafts are now "escorting"  (preceding) the UFO.

Finally, I destroyed the UFO by stopping my crafts and let the UFO pass by them, to attack it from behind. I don't know if the bug was about to reproduce, because being faster, my crafted came in range.
The odd chase had lasted more than 4 in-game hours.

Yes, I've seen people reporting the same thing with either the Shiva cannon or the TR-20 Rocket launcher, can't remember which one, anyway it only seems to happen when all weapons are cannons stick one missile launcher on them and the crafts fight normally.

Ah, there's a bug report about this already Bug #5439

Thank you for the link.

It happened tonight another time:
Supply Ship 550 km/h
Firebird all laser coming from ahead : "escorts" the target (1st screenshot)
Stiletto all laser coming from ahead/side : "escorts" the target (2nd screenshot)
Stiletto with missiles and PBW from same direction : fires missiles and destroys the target

When PBW are equipped, the bug doesn't seem to occur (I have to check the incoming direction).

So the submitter might be totally right : slower UFO, all laser craft, not coming from behind.

Well, this occurs with a laser+PBW Sarrasin, incoming from the front as well...
