Subject: [PATCH] Sync position on teleportation
|
|
|
|
We've seen many a cases where the "last good" x/y/z is desynced from
|
|
the x/y/z that is checked for moving too fast.
|
|
|
|
Theory is that when you have multiple movement packets queued up,
|
|
and the player is teleported after the first then the 2nd and 3rd come in,
|
|
it is triggering a massive movement velocity.
|
|
|
|
This will ensure that the servers position is synchronized anytime player is teleported.
