Default is 4 (extreme move fall-back) at 'default'.
Other entries by bukkit entity type name, if desired.
This allows forcing set backs for testing in a convenient way, e.g. with
setting the value to 0.3 for boat/default.
Main objective was to not reset the set-backs on setting back a vehicle
with a player, plus data resetting cleanup.
Specific changes:
* Prefer an existing set-back, in case the default one has been
invalidated.
* Do not cancel a vehicle set back task, in case no set-back is present.
* Avoid multiple resetting and redundant calls for resetting positions.
* Ensure the location set back to is set as a set-back location after
set back.
* Skip changing vehicle data with player moving resetting (e.g. player
teleport, player morepackets disabled).
Review and possibly correct/alter use of:
* MovingData.vehicleMoves.invalidate
* MovingData.vehicleSetBacks
* MovingData.clearMostMovingData
* AuxMoving.resetXYPositions
* MovingData.clearVehicleData
* MovingData.clearVehicleMorePacketsData
* MovingData.clearAllMorePacketsData
* MovingData|AuxMoving.resetVehiclePositions
* Fix scheduling vehicle set-backs: disabled by default.
* Adjust detecting already set set back in morepackets (vehicle).
* Always warn if a set-back gets overridden.
* Adjust debug logging and comments.
* Some data loss.
Looks like we're running into set-back loops, unless we can control this
otherwise. It's more safe and consistent for our context, however it
leads to nested events. Vehicle exit, player teleport and vehicle enter
will fire from within handling whichever event the vehicle checks got
called from, such as vehicle update, player move, vehicle move.
Possibly some justTeleported flag helps us here. Likely there is no
similar switch that we could use with scheduled set-backs. The proper
option would otherwise be, to use packet sending and/or even cancelling
packets selectively, which would more or less force us to hard depend on
ProtocolLib for supporting basic features of Minecraft, despite possibly
a
sensible move anyway.
* Implement VehicleMoveInfo and provide via AuxMoving.
* Use MovingData.resetVehiclePositions to reset past location on enter.
* Some auxiliary functionality.
* Route vehicle update and move through the same checkVehicleMove
method, to initialize things, making some decision about what locations
to use for from and to, and to ensure that firstPastMove is set.
* Adjustments and fixes (workaround for generics with PlayerLocation,
LocUtil.hashCode).
Prepare using VehicleUpdate and PlayerMove instead of VehicleMove for
vehicle moving. This change isn't intended to change
anything/much on the surface.
* Implement native IEntityAccessPositionAndLook for 1.9_R1 and 1.9_R2.
* Alter method visibility and parameters.
* Common pre-conditions.
* Route contents of both VehicleUpdateEvent and PlayerMoveEvent through
a common related method (also named onVehicleUpdate).
* Remove RichLivingEntityLocation, to be able to simplify more.
* Refine interfaces for locations (IGet... ISet... vs, I... for both).
* Implement location related interfaces in some places, related changes.
* Override hashCode for some of the location related classes. Use that
for storing location hashes instead of Location.hashCode. Auxiliary
methods for hashCode in LocUtil.
* Add onIce to LocationData.
* Renaming player vs. vehicles (likely incomplete).
* Possibly other related/random changes.
Line count is high for this change, despite not so complex. Next step is
to change VehicleChecks to use past move tracking to estimate from where
a vehicle is moving (left not compiling). Due to the lack of teleport
events, and due to entity last location being mostly useless, we have no
choice but to hard-set-back on anything that looks strange.
Roughly:
* Encapsulate past move tracking in a MoveTrace class.
* Have playerMoves and vehicleMoves (the latter unused).
* Resetting method for both player+vehicle including more packets each.
* Don't reset vehicle data on game mode change.
Not sure who started this, but apparently...
* NCP closes an open inventory, leading to an event for that.
* Due to the player having an item on the curser or similar, an item
drop event is fired.
* WorldGuard will kick the player due to a blacklist event.
* NCP will detect an open inventory and attempt to close it, resulting
in looping this.
Fix attempt (blind) stores the uuid of a player and skips further nested
closing of inventories.
Moving players and vehicles. Part evaluation, part preparations.
* Use more minimized types to demand for MoveData.
Likely future changes:
* Split MoveData into base MoveData extended by PlayerMoveData and
VehicleMoveData.
Might follow up:
* Might have a MoveDataStore providing the past move tracking in an
encapsulated way. To be used for players and vehicles.
* Attempt to have easy to share common auxiliary mechanics, so things
like 'mightBeMultipleMoves' and some of the associated resetting logic
can be a common routine for both players and vehicles.
* Similar.
Might follow up later:
* Don't laugh: consider lost ground to be made abstract enough to be
used for both players and vehicles.
* Track vehicles independently of players (tandem fly!).
Directly following:
* Boat fly check based on VehicleUpdateEvent and fetching last pos.
* Implement a native access based provider for
EntityAccessLastPositionAndLook, after testing the reflection based one.
Likely following:
* Implement the same fly checks based on PlayerMoveEvent for horses and
pigs too, for the case server-side fly checking is disabled.
* Configurability for individual types of enbtities, at least a flag for
activation.
* Not sure if a fall-back to VehicleMoveEvent should be kept, setup
shouldn't be all too complicated.
* Add a late in-air phase skip once workaround.
* Adjust oddSlope workaround ids to be lower-case and not contain wrpt.
* Add workaround counter for back to surface.
* Create interfaces for positions/locations. Use in RichXYLocatio,
TrigUtil.
* Add a basic implementation for isOnIce to RichBoundsLocation.
* Optimize prepare in RichBoundsLocation.
* [ONGOING] Elaborate on SetBackStorage.
Breaks access to Trigutil and RichBoundsLocation, thus PlayerLocation.
Recompiling should solve issues.
