[REJECTED] [Multiple] Player Position Update Interval

[Dreadblade]

WoW Freakz spell link: N/A
Bug description: While this might not be a bug as much as it is a custom-made server optimization, it does have its consequences.
I believe that the time required for the server to understand that one player has moved from point A to point B is too high. In other words, the interval of time between which the server receives player position updates is too big.
This has a few consequences on AoE spells that are based on player position. The most known cases are Monk's Healing Spheres and Priest's Angelic Feathers. Sometimes when you place a Healing Sphere or an Angelic Feather right in front of you, you just won't pick it up, because the server hasn't received your position update just yet. In other words, the server doesn't know that you ran right through your Sphere or Feather, therefore you didn't pick it up.

Asides from these problems, there could be other consequences too. One example is the amount of time it takes for the Solar Beam's Silence effect to disappear once you moved away from it, as this video demonstrates:

The silence should've been gone as soon as I Chi Torpedo'd out of it. Instead it lingers for about 1 more second. Also note how it takes a bit of time for me to get silenced when moving inside the solar beam.
Another consequence is that players moving at high speeds (such as players on flying mounts) appear to be "teleporting" from one place to another, instead of moving around smoothly:

Proof: No actual proof of this, but it's just a hypothesis that I'd like to be confirmed or invalidated.

Various mechanics have various implementations, it's not simply the same "time to update" for each one. There isn't any general fix to be done, just each situation/mechanic taken separately, investigated, confirming it's an issue and fixing it. But yes, some of them are intended, although too few that actually have any real impact on game play.

A specific example: Solar Beam ... this spell is some sort of "persistent AoE" which continuously applies the silence aura (which in fact has 1 second duration, not 8 as tooltip states) each 500ms. A fix for this situation would be setting the duration of the silence aura to ~100-200ms (instead of 1s) and have the "persistent AoE" to trigger the silence spell each 100ms (instead of 500ms). But, this would ONLY fix Solar Beam.

Nu stiu daca vorbesc prostii dar cred ca si fear-ul se incadreaza in acest aspect ... se intampla sa dai fear si sa vezi playerul intr-un anumit loc si el sa fie defapt in alta parte ... orice gen de fear ... Fear / Intimidating Shout etc ...

Player movement is not smooth enough, others still see you moving in small laggy teleports, "distance cuts", especially when having high moving speed, like in the video posted above.

There are many bugs related to this type of issue actually, but the most important ones are Healing Sphere and Angelic Feather, Fists of Fury, Shockwave, Cone of Cold, Dragon's Breath and many others ''facing requierment spells''. This is a very important problem since you practically lose that spell because of this.

For Healing Sphere: https://youtube.com/watch?v=TMvSjyObcgk:

1:00 to 1:06 // 1:48 to 1:53, etc.

For Angelic Feather: https://youtube.com/watch?v=jq7_YcEQhxw:

2:36 to 2:39 // 2:49 to 2:52 // 3:31 to 3:34, etc.

For Angelic Feather on Freakz: https://youtube.com/watch?v=OBZFo4n9SMs:

- Watch closely 0:03 to 0:06.

Fists of Fury: https://youtube.com/watch?v=j9EEEoO4QEc:

3:11 to 3:14, 4:11 to 4:14 or 6:52 to 6:55 ( this one being exactly the situation where on Freakz this bug happens the most ). When the player moves in front of you sideways and you use Fists of Fury in 80% cases you will see him in front of you but it won't stun him.

For others like Fists of Fury, Cone of Cold and Shockwave, Dragon's Breath the problem is that you see the target in front of you, you use one of those spells but you won't cc / stun them ( But yeah, visually they are in front of you, ''VISUALLY just'' ). As far as i observed those problems appear mostly in combat when the player position & spell delay kicks in.

Shocker, since there are many spells related to this issue, at least we hope that those mentioned can be fixed.

I tend to believe he's right. This is about player movement. Whether some spell mechanics (intended or not) are influenced by this or not, the issue still relates to player movement. It is 'chunky' and you see everyone moving in ''small teleports'', and I believe this is the right term to describe it. This happens everywhere, and melee classes usually have a disadvantage due to this.

Correct me if I'm wrong but I remember this used to happen on Cata too, at the beginning of 4.3.4, and eventually it got fixed, and along with it several bugs related to spells which were believed to be independent of this mechanic initially.

The easiest way to test is to have someone with the Sandstone drake mount in your party and mount on that person, and you will see how "laggy" you travel. It has happened to me, and even while I was as the mount and the other person pointed out the same thing for me.

Furthermore, something I observed about Fear effects:

Let's assume I'm looking at a player who has a Fear effect on himself. The game mechanic makes him move from his initial point through random points in random directions until the effect ends. In other words, let's say he gets Fear in an initial point A, then starts moving from A to B, then from B to C, and so on, towards a last point N when the Fear effect ends. I receive only the information that he's moving from A towards B and nothing more, so I keep seeing him somewhere between A and B until his Fear ends, then quickly I see him ''teleporting'' or moving really really fast towards the last point N. So if I'm a melee class and want to attack him, I can't because, while I see him standing somewhere between A and B in one place, he's actually moving through all the points towards N.

One way to solve this is to be able to receive data about his position every time he switches his direction, so that way I can know exactly where he is and what path is he moving on.

But here's where the big player position time interval kicks in and complicates stuff even further. I mentioned that I receive information about him moving from A towards B, implying he doesn't actually reach B (let's say if he keeps moving for a few seconds in a single direction with his Fear on) so all I pick up from the server is the player's position somewhere near the point where he received his Fear.

I wonder if balancing this time interval will potentially be able to fix some of the remaining crashes in battlegrounds.

Edit 1: What I tried to describe can and will be observed in the upcoming PVP event - battlegrounds between guilds.

@shocker ''Small teleport'' movement is starting to become a real issue. Especially for melee classes.

Daca putea sa repare asta probabil o facea demult timp... la fel si spell queue a incercat sa repare, dar o fi prea complicat

I've tested it recently seems like the frame lags and skipping has reduced but with the obsidian nightwing :- https://www.wow-freakz.com/spells.php?spell=121820&&name=obsidian-nightwing mount there are some skipping frames people said , with the sandstone drake it does not persist according to people.

[Sumoo]

I don't think its supposed to work like this..

[troncho]

i'm glad you mentioned angelic feather and solar beam, i've noticed this but had no idea how to describe the issue

good that it's been reported

[Sumoo]

This topic requires more attention, this is big reason for monks/priests not being played that much... Summoning healing sphere/angelic feather right under you and nothing happens.

[Dreadblade]

I'll close this topic since the problems are specific and it's not just one general issue.
