Missing spike from AI in MP

[UWBuRn]

With my squadmates i've been experiencing some problems dealing with AI fighters.

 

We were flying a mission hosted by me, where we faced some enemy fighters equipped with SARH missiles.

As we approached two of them i got a spike (lock warning), then a missile launch: i crancked and evaded the missile while my wingman pushed on the bandits. He said he had just two active (search indication) and no spike, so he continued closing. After firing on one of them he still got no spike but while keeping the lock he suddenly exploded hit by a SARH fired by one of the enemy planes, without any spike or missile launch.

 

So we made up a couple of mission to test this behaviour and it seems to happen every time: who host the mission regoulary has spikes and missile launch warnings while clients only get actives on the RWR.

One will eventually get the missile launch from ARH when it goes pitbull, but we didn't tested that in dept.

 

We kept the tracks of one of the test, recorded from both host and client side, i'm attaching them.

 

We also tried various configurations in the mission editor, as changing the task for teh AIs, placing them in different group, but so far nothing has worked out.

 

Can someone take a look to this and confirm the bug? Honestly, it seems a major annoiance for who, like us, still enjoy making cooperative missions against AIs.

 

Thanks in advance. :smilewink:

I'm at work and can't watch your tracks. But if I got this right you don't see SARH missiles on RWR, and that is how it should be, because SARH don't emit radiation them self. You can only hear the lock of the enemy that launched at you.

[UWBuRn]

I know how SARH work, but the client have no lock and no missile launch warning from the RWR when he was shot. The client just had the search (active) warning from the RWR and then... BOOM.

[asparagin]

Had the client ECM on?

This is the wingman/client speaking.

 

ECM was turned off.

One possible reason for no spike/nails on RWR is the angle at which the enemy aircraft was at relative to him... RWR has 30° scan up/down from horizontal line (parallel with the wing) so if he banks this scan zone "follows" the bank of the aircraft (for example you are locked from 3o/c and you bank more then 30° left you will lose this radar signal on RWR as it will become out of the RWR scan zone). Also if aircraft is above or bellow your aircraft (when you're level) it won't pick it up also.

[UWBuRn]

As shown in the track, the angle relative to bandits should be within the RWR scan cone.

 

People, i'm using Lock On since it came out, this behaviour wasn't there in 1.12 nor 1.02, that's for sure. Unless this is some kind of "feature" introduced in FC2 that i'm not understanding (i hardly belive that) i think that's not correct. What i'm asking is, take a look at the track and confirm you have understood the problem (look at the client track), if possible make your own test to confirm the problem. If this bug is confirmed, then it's pretty annoying and maybe the devs can take a look at it.

I don't really know how to help, but I'd like to say I've had some similar issues offline. Staring right at the enemy, they've been able to launch missiles at me without triggering the RWR occasionally. I see them in search or lock without any indication of firing, then I can check F10 and see missiles inbound.

[asparagin]

Ok I watched the track, and I think also that it looks like a problem. I watched the angles in tacview, and they were between 4 and 6° so the F-15c should have detected the launch. (I attached the file -just add .acmi)

If it is a server related problem, I can't test it on my own.

Are they definitely launching radar-guided missiles? I can believe a bug with clients not receiving some of the info they're supposed to in MP, but this happening in SP would be another altogether!

[asparagin]

I think we should stick to the given problem. Exorcet, if you have the same problem, please post a track.

[TheHawk86]

The SP is fine, it seems no prob with it.

With 100% certainty, R-27 ER.

Unfortunately, it is not the same issue, I posted because it was similar and thought it could possibly be related. To prevent derailing, I'll make a separate topic.

[Panzertard]

I must admit I've seen similair issues now & then. I'm not sure if it's been reproduced yet.

[UWBuRn]

The track should show clearly the problem.

 

Hope this can forewarded to the devs so they can work on a fix, if not for FC2 at least for future DCS modules. ;)

I had instance today where I got hit by 120 that didn't make any warning on RWR at all. I was aware it might have been fired on me in TWS and as I saw the guy in F-15 abort (as I fired on him an ER) some 10-15 seconds later I just exploded. There was nothing else around and no other spikes... only this F-15 that I had locked and fired at... I pincered and made sure my wing was lifted to pint at the aircraft/missile so it does give warning when and if the active was on me... but this didn't happen... so I too think there is either packets lost or some game bug that happens occasionally... which is weird

hi,

do you know if there is a workaround for this problem ? yesterday, i've played online and i was shot down 3 time with by a 27ER without any warning/launch indicator on my TEWS , only a scan signal

i've a track (client side only) and an acmi, the track clearly show that there were no missile launch warning

[Panzertard]

Unfortunate to see these problems slip through, all I can say is that we are working hard to avoid such problems with the DCS release.

And I have no idea what will happen for FC2 in the future, thats ED call. So we just have to wait and see if we'll see a final patch to fix these things.

[yoyo_the_reaper]

thanks for the answer

[crazyeddie]

Seems to me any bug report is a complete waste of time as regards ED, few, if any, bugs will be sorted if past performance is anything to go by. They seem to be concentrating on all the new sim developments at the expense of everything else.

 

PPPR - You work out what that means.
