The server doesn't detect/deal damage from the collisions; that would take too long. All of the damage is done on your computer.

Makes sense....so is my computer telling the server "I got hit" and/or that "I hit something" and then my computer also tells the server "XXX" is the result of that collision ?

Thanks in advance for a reply Motherland.

You mean, you're only seeing the white collision message and you are going down?  If that's the case they are shooting you.

Yes I have the message in white which says "player has collided with you". Every time this happens to me I go down in flames.

Thanks for the input guys.

I would make a small correction to your statement.  Your computer detects whether your airframe and an object occupy the same space at the same time.  If so, "you have collided" and suffer some form of damage.  (Note that collision damage need not always be fatal -- a simple fact that many have a hard time comprehending.)

"I got hit" and "I hit something" still imply that there is some kind of "at fault" mechanism at work, and there IS NOT.  Collisions are no-fault -- they simply either did or did not occur in your computer's "reality."

The other player's "reality" is slightly different due to internet lag, hence the occasion for one player's computer to detect a collision while the second player's computer did not.

Just for clarification - are you seeing this in game or when reviewing film? 

I ask because we have had occasions where people have claimed to have taken damage from a collision without receiving the orange "you have collided" message.  Usually this is because they are reviewing film and don't see the message.  However, the orange system messages do not appear on the film (i.e. you won't see "control mode 1 selected" on your film, either), which was the source of the confusion.

I've not noticed any change, but I don't think I've had any collisions (either way) recently.

Not too long ago, P38 sneaks up behind me, I never see him coming,  I get the XXX has collided with you msg..then I go down and hes fine. I dont get it. I was told that if the collision is on your screen, you get the msg..so forth. I will never understand the collison modeling here.

A P-38 sneaks up behind you and you go down.  That's it. 

You really think you went down because his plane collided with you???

How do you know "he's fine"?  He didn't die, but is he undamaged?  Unless you PM'd him and compared notes, you're just speculating.

I've always been of the opinion that if a collision occurs regardless of fault both planes should go down. Gives people who HO a less than 50/50 they love so much and would reflect a collision during a scissors more realistically. Additionally it will take away the forced collisions people do in order to get a kill when someone is on their 6.

Yes I am still of the opinion that if you get HO'd it's your own fault.

Even if it seems certain that you will lose, retaliate. Neither wisdom nor technique has a place in this. A real man does not think of victory or defeat. He plunges recklessly towards an irrational death. By doing this, you will awaken from your dreams.

Picture time again:

Pictures of an actual AH2 collision, both taken exactly at the moment of the collision:

This is what the Pony Pilot saw on his screen:


This is what happened on the P-47s pilots computer:

P-47 took no damage.

Nimble, if you are the P-47 pilot - would you still say "I should have gone down?"

No, I'll have to rethink my opinion on that. Thanks for the pics... Just wondering how large the latency is going on during these pictures if you have that info. Maybe the problem is a lag threshold that is too high? Is one a 56k connection user? Or is this just serverside? Regardless that is a big discrepancy in those pics, and it just seems to be too big for current broadband connections. Just wondering and thanks again for the pics.

Both European users with a stable ADSL connection, ping time about 150ms. With two American cyberpilots the positional differences are smaller, but still there.
And as much of the AH playerbase is located allover the world, I deliberately used two non US players to illustrate my point.

OF course our collision model is not perfect when being compared to the real world. But it's not the model's fault, it's because of the technical nature of the internet.

With current model, you have a chance to avoid the collision - steer clear of your opponent and you don't get a collision, regardless what's happening on his side. What you see is what you get.
With "both go down", you can harldy avoid a collision that you aren't even seeing on your screen. You just go "boom".


BTW, this is a .wmv movie of the collision the pictures where taken from. It's a short (3MB) clip in which I merge both player's external view into one:

That's wild ..
I think if you get HO'd it's your own fault unless you get it in the back or side or something.

Gotcha, thanks for the clarification. Still seems to be a rather large difference, but if the current model is the best we can get(150ms is pretty acceptable) with current technology support for eu broadband users, well I guess that's what we have. Thanks again, I hadn't seen those examples yet.

Wow!!  That's great!!

Need to make it an animated .gif now so you can post a "moving" explanation now.

The only legitimate explanation would be that you are getting shot and they are colliding with you on their end.  Is it possible they are shooting you as they collide?

Some of you should go do some tests in the MA using Me262s to see if it still works the same.   :t
