Subject: [PATCH] Fix entity tracker desync when new players are added to the
|
|
tracker
|
|
|
|
The delta position packet instructs the client to update
|
|
the entity position by a position difference. However, this position
|
|
difference is relative to the last position in the entity tracker
|
|
state, not the last position which has been sent to the player. As
|
|
a result, if the last position the player has recorded is different
|
|
than the one stored in the entity tracker (which occurs when a new
|
|
player is added to an existing entity tracker state) then the sent
|
|
position difference will cause a position desync for the client.
|
|
|
|
We can resolve this problem by either tracking the last position
|
|
sent per-player, or by simply resetting the last sent position
|
|
in the entity tracker state every time a new player is added.
|
|
Resetting the last sent position every time a new player is
|
|
added to the tracker is just easier to do, so that is what
|
|
this patch does.
|
|
|
|
This patch also fixes entities appearing to disappear when
|
|
teleporting to players by changing the initial position
|
|
in the spawn packet to the entities current tracking position.
|
|
When teleporting, the spawn packet will contain the old position
|
|
which is most likely in an unloaded chunk - which means that the
|
|
client will not tick the entity and thus not lerp the entity
|
|
from its old position to its new position.
