Displacement/collision problems

I grown increasingly annoyed and pissed off at these issues and I just want to confirm that Im am not the only one having this.

This is the bugreport I've recently submitted to support.guildwars.com (too lazy to type it all over again)
I have attached the screenshot mentioned in bugreport.

All I got as response is usual "omg check you connection" crap. Now I've been thru this quiet a few times, plus I have some knowledge of how IT support works from inside, so I responded like this
(Oh yes, I got pissed there)


Anyway please confirm that Im not the only one having these "connection" issues.

Happens to me occassionally, it seems to fix itself after I kill the enemies though.

Yes, I also have that problem sometimes, it also sometimes happens that enemys are shown in wrong locations.

this is definately an issue...I can trigger it on purpose too....go into autorun mode, and take a tight corner, round the edge of a strair case or something...with me this always triggers rubber banding, i will get so far up the stairs then appear at the bottom, over and over. Not sure why it happens, perhaps autorun doesn't send enough 'location data' to the server or something, so it thinks i got to the top of the stair case without ever turning the corner and pulls me back down...meh...it's very annoying.

Or you snagged onto a boundary on the corner.

i get this on a fairly regular basis when rounding up smites in UW, ive also noticed, you seem to exist in both places, i can be


X here according to sever





Y Here according to client





Z and Aggro monsters from here which is far from position x (2/3x aggro range)


they then ignore Y and head straight to X

One of my probs is sometimes when I see and enemy and I click on it to attack it my char suddenly appears right infront of the enemy but doesn't attack then it suddenly goes back to where I was before :\

My money is on a client prediction error, perhaps due to a client-server hiccup. The server is probably only managing entities and collision, with the client picking up model display, etc. The server is still telling the client that the collision model is at X,Y,Z, but the client hasn't updated the model origin to suit. As far as I know, the only way to completely annihilate this uncommon and fairly benign error is to expend more of a limited pipeline with continual sync-ing. Personally, I don't think wasting that power is worth fixing this, because it rarely happens to me, and has never really bothered me that much.

I get this often, but I assumed it was just me. I also assumed that it was problem only I saw, but one time a guildie said something along the lines of "how did you transport to the monster, then get back so fast?"

It's bizarre, that's what it is.

I can cause it on purpose too, its not lag. The link between client and server must be the issue at some point, though its crucial in pvp when your crossing a bridge sharply on a turn, it totally gets you screwed. bumped back, try again, you get free (you think your are, you cross) then your bumped back, and probably already surrounded by the enemy in the barrier corner.

Not a rant or aggrivated in anyway, though it would be nice if this could be corrected a bit.

If memory serves me right, I think Gaile Gray mentioned that Factions would improve either bumping or collisions with bridges in pvp and etc. They were going to polish this. We'll see I guess.

Edit: She mentioned it "a long while ago".

As I mentioned before I dont recall much of this problem before factions pvp weekend, so it is either update for it broke things or increased load on server did.

It's bad math in the program. That's what it more or less amounts to. There is at the core of the program an equation that defines the boundaries of certain objects and the location of certain objects. What happens is you end up with the computer putting two objects in the same space at the same time or the boundaries of an object extending beyond the graphical representation of the object. Some rubberbanding is caused by lag but a lot of it is due to collision issues and bad math.

I haven't noticed any difference since before or after. I do know that they updated the renderer (and for a few days, I had to toggle bloom on/off every time I zoned. Ugh), which may put indirect pressure on, causing a sync error.

Out of curiosity, when that happens to you, do the rest of the team/monsters also jump around randomly?

me? no...

Then I have no idea how to fix it.

Yes, has happened to me several times. Awfully annoying while running ... I've noticed this happens to me often while moving around undead Hell Hounds. o.O

well i see lots of people having the same problem... if only they would take time to report it, then ANet might even fix it...

During the preview weekend, in 12v12 battle, I was running up the hill towards my teamates, when I almost reach them, suddenly I was back at the start. I ran back again and the same thing happened. Repeat this 5x and imagine my desperation to save my teamate

Another case was that an attaxe was right in front of me and I tried to agro it as a tank, but I found myself charging head on into a big group seconds later. It turned out that the attaxe had magically teleported back into that group further away.

It could be an issue with your internet or network connection. I almost never suffer this kind of problem.
