Additionally, fix ActivationRange using global state to store
the AABBs it checks entities against. This fixes an issue where
entities would not be activated when they should be.
The region shift is configurable under `grid-exponent`, which
allows setting the region shift to any value in [0, 31]. Note
that values above 6 affect the lock shift, as the lock shift
currently is computed as max(ticket shift = 6, region shift).
The shift is left configurable for now as the lower default
shift of 2 may have negative performance impacts.
The default region shift has been adjusted to 2 from 4, and
the empty chunk buffer has been reduced to 8 from 16. These
changes reduce, but do not eliminate, player spread
requirements. The previous block range was around ~1500 blocks
at VD = 10, but is now closer to ~900 blocks at VD = 10. This
roughly reduces the area that each player uses in the regioniser
by 2.5x.
Very early build, network configuration switching is supported
but not tested (note: changes need to be backported to Paper)
Changes:
- Supports per player mob caps
- Adds entity tracker optimisations which are not in Paper
(and will not be ported to Paper due to plugin conflicts)
- No longer reverts paper distance map optimisations, as
those are replaced by the NearbyPlayers class
These changes should bring Folia in-line with Paper's optimisations
at least (probably more given the entity tracker optimisations),
still missing features like world loading / some commands
