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.
Stripping ids of hidden entities left ghost entities on clients once
the entity became visible and was later removed. Removing an unknown
entity id is harmless, so the packet is passed through.
Spectators hid HiddenBlocks in the whole arena for block updates, but
full chunk packets outside both extend regions were sent unfiltered, so
the same blocks were hidden or visible depending on the packet type.
Hidden regions are now a list: spectators hide both team extend
regions, team members the opposite one. Block checks and the per-chunk
bypass use the same regions, so everything outside the extend regions
is visible and unfiltered.
AccessPrivilegeProvider#forPlayer returns a PlayerAccess that resolves
the player's hidden region once. TechHider creates it once per outer
packet (shared across bundle sub-packets) and passes it to every
processor, so all decisions within a packet are consistent and the
region/referee lookup no longer runs per block on the netty thread.
The processor for ClientboundEntityEventPacket used getEventId(), the
status byte (2 = hurt, 3 = death, ...), as the entity id. Events of
hidden entities therefore passed the filter, and events of visible
entities could be dropped when an unrelated hidden entity had the same
id. Use the entityId field instead.
The line no longer needs start, middle and end parts that were moved
around the player. It is one display that is visible for a player as soon
as any chunk the line passes through is in their view distance.
REntity#canView now receives the chunk positions of player and entity.
Entities now decide per player whether they are visible. REntity defaults
to the player view radius, RDisplay derives it from its viewRange (1 = 64
blocks) capped at the client view distance, so values like Float.MAX_VALUE
stay cheap. Changing the viewRange re-evaluates the viewers. Fixes#488
Send ClientboundEntityPositionSyncPacket instead of the teleport packet so
relative moves keep working afterwards, and pass rotation in degrees.
Pass the velocity unscaled to Vec3 instead of pre-multiplying by 8000.
Fixes#247
PacketProcessor passes Bukkit EquipmentSlots to REntity#setItem, which cast
them to the NMS EquipmentSlot. Take the Bukkit slot and map it to the NMS
slot when building the equipment packet.
RPlayer requests the skin asynchronously, so the first tab list packet is
usually sent without textures and viewers already in range kept the default
skin. Re-send despawn/delist/list/spawn to the current viewers once the
skin response is received.
Chat is now handled entirely by VelocityCore through channels with
separate readers and writers (Global, Local/Fight, Blue/Red fight team,
Team, ServerTeam, Alert and 1:1 direct messages). Each player has a
saved default channel; messages from other channels are tagged with
the channel name, and every default change is announced.
- /global, /local, /tc, /stc, /msg and /r switch the default channel
when called without a message
- /chat <channel> switches, /chat <channel> join|leave toggles reading
(saved); moderators can join arenas by name and write with
/chat <channel> msg <text>
- '+' sends from global to local and from local/fight to the fight team
- Referees write yellow in the fight chat
- Subservers no longer receive chat; arenas get a record-only
ChatRecordPacket so replays keep their chat
- Remove the chat listeners of SpigotCore, FightSystem, MissileWars,
TowerRun and TNTLeague
