HullHider gets a hideEntities parameter: the fight still hides entities inside
hidden hulls, /hullhider only hides blocks. As the TechHider also dropped
spawn packets at hidden positions, ForPlayer#canAccessEntitySpawn decides
about them now, which the BauTechHider always allows.
/hullhider hides the inside of the build area hull of a region from the
players who toggle it, like the hull hider of a fight. Each region gets its
own hull while somebody uses it; it is rebuilt every time somebody enables it,
as WorldEdit and Axiom changes do not update it. /techhider, /xray and
/hullhider exclude each other per player and region.
Which players may see the hull contents is now decided by Viewers, a sealed
class with HiddenByDefault (fight) and VisibleByDefault (bau). Added players
are stored in a set; isViewer alone defines what being added means.
HullHider#removeHull stops hiding a hull: it shows the entities and REntities
the hull hid and resends its chunks to everybody who could not view it. A hull
is enabled again by adding and initialising it.
Hull#resendChunks only resends chunks the player has loaded. HullHider now
resends the chunks to non-viewers after initialising a hull itself, so
FightHullHider no longer does it.
The new TechHider registers a permanent global filter, so BauSystem now uses
a single BauTechHider that combines the hiding rules of the spectator
techhider, /techhider and /xray per player. To support the different
obfuscation blocks of these rules, ForPlayer now provides the obfuscation
block per position.
The ChunkHider now also checks single valued chunk sections, which were sent
unfiltered before, and recalculates their block count if they change.
Unhandled packet types are logged once; statistics, debug samples and ping
responses are passed through.
The legacy TechHider and its access widener entries are removed.
ObfuscationConfig resolves the hidden blocks, block states (including all
waterlogged states when water is hidden) and block entity types plus the
obfuscation block, either from a gamemode's techhider config or from plain
materials. TechHiderWrapper now only contains the fight specific access rules.
Hull no longer depends on FightSystem: plugin, world, region, ground
visibility and hidden blocks are passed in. HullRegion is the common block
box hulls work on. The generic HullHider<K> manages one hull per key and does
the block, entity and REntity tracking; FightHullHider keeps the fight
specific parts (team hulls, viewer rules, state dependent registration).
Entities are now checked against the hull with block coordinates, so entities
in the bottom layer and at the max z edge are handled correctly.
HiderCore holds the TechHider, ChunkHider and AccessPrivilegeProvider so that
FightSystem and BauSystem can both shade it. BlockIds and ProtocolUtils stay in
SpigotCore (used by AntiNocom and RFallingBlockEntity) and move to
de.steamwar.core to avoid a split package. The access widener entries the
TechHider needs are duplicated into hidercore.accesswidener; the legacy
TechHider still needs its own copies in SpigotCore.
