Je n’arrive plus a retrouver la source mais voila ce qui avait été écrit dans un blue post :
Les layer de STV et ashenvale fonctionne différemment du reste du monde.
Dans ces zone tu as énormément de « layer » en plus, pour avoir au maximum un certains nombre de joueurs dans la zone.
Ok j’ai retrouver une source mais c’est différente de ce que j’avais lu :
Everyone does the same thing. Uh-uh, now we have a lot of people in the same STV, we’re going to start lagging if we can’t keep the population under control, but everyone keeps pulling in more people via groups. A new value takes effect here, « Max ». When we exceed the Max value for a zone, we stop caring if you have a layer reservation, and we stop caring if you’re in a party with someone. The copy of this zone is full, we can’t keep sending people there or its going to fall over.
This is one of the big issues you’re facing at the moment in STV. Since everyone is forming 5 man groups and usually one person arrives ahead of the others, its running into the Max value for the zone and not allowing the rest of your group to come into the same copy of the zone. Think about it, if the zone can handle 500 people, and allows them all in then they each invite 4 more people, ah crap, we’re going to crash. So we have to have a hard limit somewhere.
- Getting layered unexpectedly after you’ve managed to all get together. This is the first one that I would consider a bug and not just a bad user experience (some bad UX when the alternative is the server dying is OK). Based on what we currently know, if 5 people are all together in the zone in a group, they shouldn’t get split apart after that point, but folks are reporting just that, so that’s one we need to dive into and figure out what’s happening. Now, the good news is Classic is already working on a change that will keep parties together (so even if you move layers, you all move layers together) which will mitigate this issue but there’s still a behaviour here that isn’t expected that we need to get smarter on.
So there you go, that’s enough for a Sunday deep dive. The TL;DR? Groups are hard for the layering system to handle, and once a zone is full the UX at that point is gross. As the Classic team already mentioned theirs changes coming to help improve that, and my end I’ve been noodling the Target & Max values to try and find the sweet spot between Lag and Groups.
As always, if you find this sort of thing fascinating, consider a career in Design or Engineering! Game’s are fun and hillariously complex beasts to work on but very rewarding.
