Cobra mini-gun bugged (Confirmed, have workaround)
Lagomorph, Xeil and I spent about 1.5 hours researching this bug last night on the private server. We figured out how to fix it reliably, and as it turns out, that fix matches the one posted on that same EA here:
http://forum.eagames.co.uk/viewtopic...ghlight=#47757
which was linked to in the "Cobra Minigun Bugged" thread:
We also managed to pretty well nail down the cause of the issue.TO RE-CALIBRATE: Max out the view direction of the chaingun in the 4 different corners of the screen. If for example, the server thinks you're looking 20 degrees left, and you think you're looking straight, by moving your aim all the way to the left of the screen, you will now both agree that you're angle is the max_left_view_distance (i dont know what the max degrees are.) If you do this for all 4 corners of the screen (I think you can do 2 opposite, but I'm too lazy to check my geometry...) the server and client will again agree on your direction, no matter how you were miscalibrated before.
What it's definitely NOT:
1. Infantry
2. Infantry being prone
What OFTEN causes it:
1. Switching to TV-view and back while the chopper is in rotation (rudder, steering left or right).
We tried LOTS of different movements, but the only one that worked a significant percentage of the tries was the one I just described.
It is NOT just the Cobra, but any attack helo.
Summary:
Anytime you change back from TV view, I'd recommend doing a quick 4-corner sweep with your gun.Last edited by StrikeFear; 08-04-2005 at 08:58 AM.

Thanks StrikeFear, I was doing it today. As soon as I came out of TV mode I'd just wiggle the chaingun to all four corners and I was good to go.

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Wow, did this have me confused for a good hour. Every time we came up with a decent hypotheses it was broken next attempt. I recall early on seeing bullets from the turret landing all over Xeil (doing nothing) and over in the corner of my screen I see an explosive barrel go off. 0_o
Another thing I will mention: It seems that the property of being "mis-aligned" is attached to the helo not any of the people involved.
- As long as it is the same instance and no gunners have done the corner fix, it will be broken for anyone gunning. (Our very first "fix" for this bug was destroying the helo and getting it when it respawned...I'm sure you can see how this would be a bit impractical for every time you want to use a TV missile.) ;P
One final point of intrest:
There is often a sort of "stutter" when changing between the two weapons where it seems to switch your camera back to the previous weapon for a split second before resuming normal operation.
- I believe that this stutter is involved somehow. At the very least it is an indicator that your gun may now be mis-aligned because even in the "worst" conditions for switching weapons, every single time that the stutter did not occur the gun was not mis-aligned afterward.
There isn't much to be done about this last point, it's just interesting to know. ^^Combat is very simple, there is a first place and a second place. Second place is laying face down in the mud...sometimes, so is first place.

Re: Cobra mini-gun bugged (Confirmed, have workaround)
I was trying this last night myself...Xeil knows how good I can hit infantry when it works
With the Cobra I was able to take infrantry out left and right, as if I was flying in the MEC grenade launcher.
All I did after coming out of TV view was move the gun all the way left and then all the way right. Seemed to work for me.
I was hoping to see you last night, Xeil, so I could have gunned for you. You provide me the steadiest/safest platform I've seen yet. You need to get on XFire so we can coordinate

We confirmed that Left/Right maxing does NOT always work. Sometimes you MUST max vertically as well. Originally Posted by Telorn

Re: Cobra mini-gun bugged (Confirmed, have workaround)
And I would do it that way while not in a combat situation...but all four corners can take some time, time that I don't have in a heavy combat situation..and let me tell you..that is the worst air combat (hectic) I've ever seen on Dalian Plant last night! My pilot could never give me a steady platform because he's constantly being painted. Originally Posted by StrikeFear
So in dire situations, a left to right typically seems to work well enough. Just move the gun a little up and down the target to be sure you actually 'hit' them. When not in a hectic situation, I'll do the 4-point.Telorn

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Sheesh. I forgot to mention this important item:
The "fix" for the problem is sometimes undermined if the helo is doing a hard rotation. (That's yaw, left-right, turning motion. Not rolling, not pitching.)
The same motion which is involved in causing the problem also appears to be an issue when fixing it."You live and learn. Or you don't live long."

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Hehe, were you guys able to duplicate that one video I linked? The Cobra on the ground firing at two guys 6 feet in front of him until the canon overheated, but not doing any damage at all. That was just amazing.
Anyone ever managed to rack up TK's due to the bug?

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Yeah. It seemed that whenever I'd fire on infantry, thinking they were enemies, the gun would hit just fine and kill them instantly..but when they were enemies, the gun would bug. Had quite a few that way Originally Posted by perry

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Yes, we were able to pretty consistently "break" the gun. And 100% consistently "fix" it - if the helo is not spinning too much. Originally Posted by perry
The behavior we witnessed was just like in the video. Aiming and firing, and everything looks right - but no damage. We were able to get the angles to be incorrect, but only slightly off, such that firing at a spot, say 10m to the right of a target would hit the target."You live and learn. Or you don't live long."

Re: Cobra mini-gun bugged (Confirmed, have workaround)
Very interesting! Thanks for givin us the heads up -- I'll test this out myself later. Was going nuts the other night not being able to kill any infantry.
