This should be better in case the vanilla command allows UUIDs some day.
At least during testing in uuids did not work, so we added a warning
message if uuids are used for banning.
Using player names for actions should be safe anyway.
Access by id may or may not be changed internally, depending on what
happens on the API side.
For performance reasons we might like to do without passing on extra
stuff like Material, or even do String-comparison.
If ids will become more expensive to use than other ways, or if it will
be possible/accepted that ids get reused during runtime, then we will
have to change all internals.
A merge can happen if the maximum distance between any two points
exceeds the merge distance, because LocationTrace attempts to balance
distances entries. Thus this test must not bne able to walk further than
the merge distance.
For whatever reason it was commented out, it is now put back, assuming
that the reason was "it did not help with mcMMO", because mcMMO used to
fire extra BlockBreakEventS.
Now we use a tri-state and set it to MAYBE if instantBreak is set
already on lowest priority, to have a rough indicator if a plugin set
it, or if the server might have done it. Later we might let FastBreak
assume some maximal duration for either case, instead of ignoring these.
Fixes:
* On passable-violations useLoc might have been passed as newTo.
Reduce potential for accidental future misuse:
* Call useLoc.setWorld(null) as late as possible.
* Do not reset world of MoveInfo.useLoc in MoveInfo.set.
An implementation for NCPCompatBukkit is missing.
Note that the native access can not set lastYaw nor lastPitch in
PlayerConnection (private), but it could set lastYaw and lastPitch in
EntityPlayer.
Can't guarantee this actually helps with stuff like derp/magnet, because
we can not really set the outcome of a PlayerMoveEvent without
rubberbanding the whole planet. Hacks could send enough packets per tick
to keep freezing people - we might be able to keep track of yaw/pitch
correction and cancel (most) attacking for the same tick after yaw
correction (invalidate "same" with in-bounds yaw).
