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.
