Similar to TestNCP but reduced/different features:
* Config: trace for the log file and notify to send to notify channel.
* It's not possible to confine whose messages you receive (yet).
Meant for better local/quick testing in the first place.
* Make attribute methods consistent (remove the sprint boost modifier
from the generic speed multiplier, because it's inconsistent).
* Add missing implementations.
* Adjust default sprinting speed modifier.
* Add more guards for the latest compat module (1.8_R3).
* Add a reflection based compat module for CB, to cover minor updates.
* Possibly other minor fixes/changes.
[Hail "insufficient data written"!]
When the respawn/login location is obstructed, the respawn event shows
that location, but the first move will start at several blocks above,
without having a teleport event to rely on, thus this workaround.
Vertical velocity handling can be much simplified (and possibly extended
to including downwards velocity) with using a friction-based modeling.
Absolute envelopes can still be checked extra, where appropriate.
Not very efficient in terms of code-output, but enabling us to log test
cases for visible (and potentially passable too), using real-life
examples.
* Add the capability to log a FakeBlockCache as java code.
* Add utility to record map parts (cuboid, ray-tracing with margin) to a
FakeBlockCache.
Missing:
* Actually log stuff (visible).
This is not the thing (lots of yet), but it is a small step.
Refactor:
* Use access methods for several details on vertical velocity.
Fixes:
* Dont reset the current jump phase if there is vertical freedom left,
because the next jump might then cause a violation.
* Fix clearActiveVerVel (remainder used to clear hVel, yet unused).
* Clear vertical velocity on removeAllVelocity (!).
* Keep setting sfDirty if velocity is found, to prevent premature reset.
Missing:
* Some resetting conditions for sfDirty might be missing.
* Implement an error counter increasing with velocity-add by 1.0 or
slightly more , decreasing with violations, but undo violations if count
is > 0.0. Use at least for vertical accounting, in order to go stricter
on cheating with velocity.
* Revise setting sfDirty on horizontal velocity as well.
* Switch to AxisVelocity (vertical), accounting for + and -.
* Use a LinkedList for storing past locations (prevents overriding if
t_last = t_now, also allows storing differences there right away).
* Calculate the yaw difference vs. the maximally possible value (180).
* Add switching the target as an extra weight.
The workarounds in InteractRayTracing and using multiple
reference-targets in Visible have all been removed in favor of using the
actual looking direction for ray-tracing.
On quick testing, there remain false positives, allowing to somewhat
escalate violation levels, if intended to. On normal playering false
positives seem to happen very near the very edges between blocks on
occasion.
* More tests for PassableRayTracing (room, rays from outside).
* Alter InteractRayTracing to account for the block interacted with.
* Added tests for InteractRayTracing.
Problems:
* RayTracing may end x-th digit off target, thus in the wrong block.
Suggested fix is to keep correcting t by the absolute coordinates of the
blocks, i.e. calculate the absolute position rather than adding up.
* InteractRayTracing with strict set to false (like in the
blockinteract.visible check) will be too lenient with 1-thick wall
setups and fail test cases.
Previously only "random" transitions were taken, for simplicity. For the
sake of better debugging and consistency we check all combinations of
transitions now, calling the iteration with all transitions done at once
the "primary line", while calling step with a subset of transitions done
would be the "secondary line".
Currently an iteration might still end x-th digit off the target, so it
does not necessarily end on the target block itself. This is not a
problem for passable, but might be one for interaction and other
applications, thus this should be fixed at some point.
To avoid cheaters accumulating velocity dealt by damage, we skip dealing
fall damage, if they would not have received any, without taking the
current move into account. This is only for the case a player causes a
violation for which NoFall would usually have dealt fall damage.
* Update lastKeepAliveTime from KeepAliveFrequency (even if that is
disabled).
* Update lastKeepAliveTime from FlyingFrequency too.
* Allow to test for feature tags efficiently.
* lastUpdate is always set calling update().
* Negative diff can not affect update (time ran backwards).
* Use lastUpdate instead of lastAccess where appropriate.
* More comments/formatting.
While we can/could control which stream to log to within onDisable, we
should still assume that an asynchronous task could be using the logging
system. Since we don't have a clean entry to onDisable, we have to catch
the exception.
* Extend CheckConfigFactory with a remove-all method.
* DataManager.clearConfigs() now uses CheckType for getting factories.
* Split off Check.hasBypass method to check exemption + permission.
* Allow null permissions in CheckType (interpret as no bypass).
* Add Check types for FlyingFrequency and SoundDistance.
* Add exemption and actions to FlyingFrequency, alter defaults.
* Add a test for moving a simple config value (not sections).
* Add a flag to @Moved to allow explicitly skipping sections.
(Should enable moving values into a child path of the previous one.)
* Don't set values before inside of processMoved...
First attempt to detect if a moving event would fire. This might not be
100% accurate, as a) we can'T really know and b) lastTo is not minitored
in the most reliable way (e.g. teleport on highest priority, resetting
logic favors set-backs).
* Use a HashMap for data, as we intend to use the primary thread.
* Move redundant move checking into a method.
* Ignore on-ground, if it is sent too often.
* Log if redundant move checking has to be disabled.
Removes access by name and entity-id for now. Access by name might be
re-added, though any kind of mappings will likely be maintained
somewhere near DataManager.
Measuring the time from sprint to attack doesn't work well. The
ctrl-sprint thing also adds to it. Better would be measuring the
toggle-sprint frequency and possibly combine it with some other measure
(packet level attack frequency?) then rather deal attack penalty time.
We can now decide on base of the Minecraft version, which value to use,
with the config entry set to "default". Used with
pvp-knock-back-velocity and enforce-location (first move exploit).
Activated features are shown in the version info ("ncp version"). The
version info is now logged to the log file after post-enable and after
reloading the configuration.
* Add methods to NoCheatPlusAPI to add/set/get version tags.
* Display all tags in the ncp reload command.
* Alter test framework to set a dummy API.
* Add tags for blocks, net checks, FastConsume.
