The vanilla behavior for most mobs is that they just stop minding their
targets' business if aggro is lost. The same applies to guardians and
elder guardians.
To prevent the pace of gameplay from stagnating, MobArena compensates
for target loss by helping the mobs find a new target. The issue with
this in terms of guardians is that breaking line of sight is the only
way - besides killing it very quickly - to avoid taking damage from a
guardian due to its lock-on laser attack. This means that guardians and
elder guardians need to be excluded from the retargeting logic to make
sense in an arena setting.
This commit introduces a new EnumSet of EntityTypes to exclude from the
retargeting logic. It is not a particularly pretty solution, especially
not since ArenaListener is such a huge class already, but it does make
it easier to add more mobs later down the road, and it does a slightly
better job at giving way to a config setting at some point.
For the Mobs Rework, a per-monster flag like `auto-retarget` or similar
might be a much better solution, so it's possible to have encounters
like a small batch of guardians that _don't_ lose their targets but have
very little health, so the "race against time"-aspect can exist, but in
a much more configurable way.
Fixes#601
This commit fixes the per-arena config setting `soft-restore`. Due to
commit 92c4ce1a8b, the soft restore logic
won't run on BlockBreakEvents, because to reach that specific part of
the event handler, the `protect` flag has to be set to `true`. However,
due to an early return in the soft restore logic if the `protect` flag
_is_ set to `true`, it is effectively impossible for it to run.
The fact that this functionality has been broken for over 6 years (!)
with almost no reports of it is perhaps a testament to how little it is
being used in the wild.
The integration only works reliably with the `clear-wave-` settings set
to `true`, because it relies on there being only one "current" wave.
This is a fundamental issue with the way sessions run right now, and is
another good example of why the Sessions Rework is necessary.
It is possible to achieve the exact same functionality by just making a
couple of Upgrade Waves before and after the waves that need to have
limited skill sets (thanks Lucy). With just a couple of quality-of-life
features like wave "triggers", it's possible to make things just the way
they were with the integration, but by using some more general building
blocks.
Closes#609
Catches ConfigError and prints its message rather than letting it bubble
up to the command handler as an uncaught exception. This means that
instead of seeing "An internal error occurred...", command senders now
see the underlying error message, as well as a short message telling
them to fix the error in the config-file and reload.
Closes#599
Jitpack is the recommended Vault repository now, and we've actually
already updated the comment for Jitpack to include Vault previously, so
let's just get rid of the HeroCraft repo now.
This commit fixes the `player-time-in-arena` per-arena setting by switching to `toUpperCase()` on the string value, which means that the values can actually result in something meaningful, rather than always throwing an exception.
The feature was broken in commit b1c6b61827, and it appears to be the only such instance to sneak through.

This commit completely reworks the Root Target ability implementation by
replacing the repeated teleportation code with potion effects.
The old implementation relied on teleporting the target every tick for a
given duration, but because teleporting also involves pitch and yaw, the
result was a constant "snapping back in place" experience.
The new implementation works by applying the following potion effects
with a very large amplification:
- Slowness, to prevent the player from moving out of place.
- Slow falling, to negate fall damage.
- Negative jump boost, to prevent the player from jumping around.
Note that the jump boost uses a _negative_ amplification to make it have
the inverse effect, i.e. a much worse jump ability. It is still possible
to jump an arguably negligible amount away from the root location.
Fixes#490
This commit nukes the readthedocs documentation from the repository, but
it is kept as a local backup.
The RTD effort was a valiant one, but it fell by the way side, mostly
due to a lack of attention from my part. At this point in time, the wiki
and RTD have diverged too much, and I would rather have just one place
for documentation than two that are out of sync.
If we ever pick up RTD again, it's probably going to be with a complete
documentation rework in mind.
Makes the class chest armor guessing logic pair `"ELYTRA"` up with the
chest piece slot. This specific matching works, because there are no
underscores in the `"ELYTRA"` item name.
Fixes#616
If someone spins up MobArena with a really old config-file or simply
removes the `pet-items` section, the plugin throws an NPE. This commit
fixes that by allowing the section to not exist.
It might be a good idea to log some helpful information, but let's wait
and see if this isn't good enough.
Fixes#606, closes#608.
Thanks Chew!
Adds support for a new `ready` state in the template engine for arena signs.
A sign is in the `ready` state when there are players in the lobby and all of them have readied up. This is only relevant in arenas with start delay timers, as the arena session automatically starts when all players are ready otherwise.
The new state is completely optional, even when no base state is provided, and it inherits from the `joining` state when not defined.
Closes#593
This commit adds support for listing arena players on arena signs by
introducing the following _dynamic variables_:
- `<arena-n>` the _nth_ live arena player
- `<lobby-n>` the _nth_ player in the lobby
- `<ready-n>` the _nth_ ready player in the lobby
- `<notready-n>` the _nth_ player in the lobby who hasn't readied up
Each variable points to a list of players (sorted by name), and the `n`
is the index into that list (1-indexed). This means that putting the
variable `<notready-1>` in a template will result in the name of the
first player in the list of lobby players who haven't readied up, sorted
by player name.
Implements #592
This commit changes how the ArenaRegion `intersects()` method works:
- The implicit null checks in the `setup` and `lobbySetup` flags have been replaced with actual null checks inside the auxiliary `intersects()` function. Not only does this make the auxiliary method more robust for potential future use, it also helps tidy up the code a bit. So neat!
- The semantics have changed, since `setup` depends on more than just the `p1` and `p2` points. This fixes an (unreported) bug where the check would report a false negative in case an overlapping arena region was defined, but e.g. the arena warp was missing.
- Instead of only checking arena vs. arena and lobby vs. lobby, we now also check arena vs. lobby and lobby vs. arena. That is, if the arena region is defined, we check it against both the arena region and lobby region of the other ArenaRegion (if they are defined). Same deal with the lobby region. This should ensure that no combination of overlaps pass through the check.
This commit fixes an issue with the new `intersects()` method on ArenaRegion. Instead of blindly assuming that the region points `p1` and `p2` are set when the method is called, we first make sure both regions are properly set.
Fixes#590
This commit introduces an `intersects()` method on ArenaRegion that
allows us to check whether two regions intersect.
The new method is employed in ArenaMasterImpl during arena load. If an
arena's region intersects with any other arena's region (in the same
world), we print a warning to the server log.
Fixes#367
This commit introduces a null check in the ConfigUtils `parseLocation`
method. If the world of a location string does not exist, the method now
throws an IllegalArgumentException, which allows callers to fail more
gracefully instead of having to resort to null checks.
Additionally, the parsing of exit warps, leaderboards, or linked class
chests is wrapped in try-catch statements that re-throw ConfigErrors
for better error reporting.
Fixes#421
This commit removes the old version checker that used the DBO resource
page and replaces it with a custom checker that uses the "legacy" Spigot
resource API. The Spigot API is much more lightweight and doesn't
require any sort of parsing.
The new version checker uses a simple cache, keeping version checks
fresh for up to one hour, reducing the need to go fishing on every op
login. The cache resets on restarts, though, but this is acceptable.
Note that no attempt has been made to ensure correctness on multiple,
consecutive invocations when the cache is stale. If a cache refresh is
initiated, all update checks invoked before the cache refresh has ended
will behave as if no update is available. This is acceptable, because
update checks are non-essential, the time frame is extremely narrow, and
the most common result of an update check is "no updates available",
since the amount of update checks made is vastly greater than the amount
of updates released.
Since the actual execution of these commands use the regular player name
instead of the display name, the tab completion is useless if it doesn't
also use the regular player name.
Fixes#589
This commit is a complete rewrite of the target event handling logic in
the ArenaListener class.
Instead of the complex, inconsistent code structure with too many line
breaks between control flow branches, we just have a thin logic wrapper
that delegates the event handling to smaller, more focused functions
that handle arena pets, arena monsters, and foreign entities on their
own.
A couple of auxiliary methods are introduced to try to limit the amount
of warnings produced by checking set membership with `contains()` when
the entity/target is an Entity and the collection is a sub type.
Fixes#572
This commit removes a condition in ArenaImpl#canJoin(Player) that checks to see if the arena's WaveManager has any recurrent waves.
Removing this condition is safe, because the WaveManager already makes sure to have a "catch all" default wave at hand for when no wave definitions match a given wave number. As such, the condition in ArenaImpl is completely unnecessary, and was in fact the root cause of a bug.
Fixes#566
Due to the package structure and location of MASpawnThread, SpawnsPets doesn't need to be opened up for this to work.
This change opens up for quite a few different upgrade strategies, since pet items obtained outside of Upgrade Waves are transformed as well. It is technically a breaking change, because it breaks the invariant that "after arena start, no items are transformed to pets". However, since pet items are customizable, it is possible to just change the `bone` to `sponge` in the config-file if bones carry some sort of implicit meaning in an existing setup.
Closes#524
