Author Topic: Mid-air collision bug? (Read 5477 times)

Hyrax81st · « **Reply #15 on:** August 15, 2004, 11:25:54 AM »

Just a quick question and a point of curiosity.

The P51 is still firing away at something even though the film shows the F4U is belly-2-belly with it. Did the P51 still see the F4U as in front of it even though the film shows differently ?

It appears that lag plays some part in this. If frames 3, 4, 5 and 6 are the closest point of contact behind the F4U, then the collision bubble is quite large (at least with regard to the planes - not quite as large if you consider the prop diameters of both planes). But due to lag, the P51 is still firing at his target directly in front of him. Could the P51 have accidentally rammed him on his FE ?

Anyway, by the time it registers as a collision, the FE starts showing the P51 breaking up sometime between frames 6 and 7 - but the F4U never had the encounter so he flies away undamaged.

Is there anyway that this snip of film can be posted ? I would love to look at it.

Turn off collisions HTC, or fix it. And please, don't make the customers wait two weeks for the next major patch while their frustration grows. That last patch to the collision model was a classic case of fixing what wasn't broken.

My regards,

From the snapshots in this one looks like about a 15-20 ft separation that still registered as a collision.

If this is taken from the film of the Mustang pilot, it completely eliminates the supposition that the Mustang disintegrated because the Mustang pilots F/E saw a collision, and the Corsair pilot did not disintegrate because his F/E saw no collision. This is the problem I've always seen with the AH collision model in every form it has taken. And I still think the idea of a "single plane collision" is pure Bravo Sierra. Either TWO planes COLLIDED or TWO planes DID NOT .

No more calls please, we have a winner.

Virgil et al. , for god's sake, could you please read this?!
It's old of course, but the basics are still the same.

Note: I agree that there seems to be something wrong with collision in patch 8.

Excellent link on the effects of Net Lag...especially the relevant section on collision.

Id rather have them completly removed than to deal with the ever lasting question as to wether there was a collision or not. Then listen to the lame Lag excuse. Just remove them and the question is gone forever.

You must have a very good connect

Mine is 37333 dialup and lag is definetly playing a part during some fights.

No cable or DSL available where I am

I keep checking

Got planes jumping over a 100 ft. at times

Happens sometimes when I'm close and fire and plane jumps away as my bullets leave the barrel. My tracers pass through the empty space.

This collision stuff suggest to me that the bubble was extended trying to find out why it wasn't working and then the real reason was found and fixed but the bubble was inadvertantly never reduced?

Hyrax:

The film loop was taken from me in the P-51. My FE registered the collision. The frames you see are the closest I got. The guns are still blazing because it was a high speed pass and the F4U was rolling away pretty quickly. The F4U didn't lose any parts and was maneuvering for a shot after I lost my parts.

I'd be happy to post the film clip after I chop it up so that we can see just the interesting pieces of the film in question.

Look lucull, I've read it several times, and I do understand it. Still, one plane can't collide, it takes two. One plane won't get away with no damage, and to penalize one plane for lag and not the other is absurd. That notion is a joke. You cannot collide with empty air space. Oh, and lose the "for god's sake" Bravo Sierra histrionics too, okay?

did he have a name and a 15ft forcefield around him?

Thanks for reply Hitech. I hope the patch is out soon.

Hof's article still explanes it pretty good, but if you still demand that both get the penality arguing that it takes two to collide, than it's totally clear that you don't understand the article and the effects of netlag or you are simply ignoring reality.

However, understanding the effects of netlag makes your demand absolutly senseless.

Note: 1. netlag does not imperativly include that >= 1 has a high ping.
2. even with yourself and your opponent connected directly to the server, you would still see a difference on both FEs due to the server process time (this diffenrence would be really small, but still a difference).
