The place/portal async function now track entities that have been
removed from the world but have not teleported. When the server
shuts down, these entities will have their passenger tree restored
and re-added to the entity slices at the location they were teleporting to,
or in the case of portals that did not run placeAsync yet,
the location they entered the portal on. This should ensure that
for regular teleports that the entity is placed at its correct
target location, and for portalling to ensure that either
the entity is placed at the portal entrace location (where
they entered) or the portal destination. In any case,
the entity is preserved in a location and will survive
the shutdown.
Additionally, move player saving until after the worlds save. This
is to ensure that the save logic is performed only after
all teleportations have completed.
Fix some other misc issues as well:
- Fix double nether portal creation by checking if a portal exists again
before creating it, fixing a race condition where two entites would portal
and neither would see that the other created a portal.
- Make all remove ticket add an unknown ticket.
In general this behavior is better since it means that unloads will only
ever occur at the next tick, rather than during the tick logic. Thus,
there will be no cases where a chunk is unloaded unexpectedly.
- Do not use fastFloor for calculating chunk position from block position
It is not going to return a good value outside of [-1024, 1024]
- Always perform mid tick update for ticking regionised player chunk loader
If no entities were loaded, no chunks were loaded, and nothing else -
the logic would not have otherwise ran. This fixed some rare cases of
chunks never loading for players after logging in.
The simple solution is that we ignore entities/positions that are not
in the current region. Making retrieval of items in inventory
thread-safe is not going to happen.
This is so that it may be accessed concurrently
from many regions.
Additionally, make sure it does not leak memory by limiting
the number of entries it will cache.
Now, all of the sleep status changes are pushed to the global
tick thread. Had to modify the wake up all players routine
to use the task scheduler to ensure the player is woken up
on the right region context.
Fix erroring while crashing on the global tick thread due to
region field being null.
Now, the spawning should be running Vanilla logic; except
that it is calculated per region (which is what per player
was effectively achieving anyways).
Will be removed later once this is all public.
Fixed many issues with teleporting players on vehicles
while in the same region.
Additionaly, make sure dead players are dismounted - as
this logic was previously done by remove.
Re-add regiontodo.txt
Because game time is now on the global tick thread, we no longer
need adjustments for any block entity. But, just in case we do
updateTicks functions now.
