The whitelisting approach works well for the legacy builds, because the
version landscape doesn't change with those. However, the main build on
the master branch will not run on a server version other than 1.13, so
come 1.14, MobArena will be broken.
This commit fixes this problem by changing to a blacklisting approach
for the main build on the master branch. Checking for versions that the
build *can't* run on brings back MobArena's old resilience to version
changes on the Minecraft side of things.
The previous hardcoded value of `20.0` works in most cases, but if a server uses a base health higher than 20, players don't get a full heal. Worse, if the base health is lower than 20, MobArena crashes when it tries to set the health to 20, which is now out of range.
This commit introduces the Attribute enum to MobArena's code base and uses it to get the base value for player max health. This should fix the aforementioned issues.
Fixes#513
Instead of explicitly ALLOW'ing a teleport if a player has the permission, we let the teleport handler logic run its course. If an arena explicitly REJECTs the teleport, we need to cancel the event, but the permission now overrides that behavior. This means that only in the case of an impending event cancellation, the permission kicks in.
This is important, because the permission is supposed to override the decision to cancel, rather than drive the decision to uncancel. With this change, MobArena never uncancels something it wouldn't have uncancelled otherwise, meaning it won't interfere with teleports outside of its own context, and thus won't interfere with other plugins.
Fixes#515, closes#516
Thanks to @minoneer for the bug report and pull request that this code
was based upon!
Spigot is at it again with another breaking change to the API where the
JavaDocs have been retrofitted to match the new, ancient way of writing
software.
The addItem and removeItem methods originally just added or removed
whatever they could when called, and returned a map of items that failed
due to lack of space/items. Now, with the breaking API change, these
methods actually *mutate their arguments* - a practice that has been
heavily discouraged for decades in modern software development, and
something you usually only see in C these days. This change, like many
others in the same vein, show the complete recklessness, incompetence,
and lack of awareness from an otherwise talented team of developers.
Hopefully, they will continue to hone their skills so that we can
eventually have a stable API again.
From a purist standpoint, the flySpeed tag should never be messed with
in MobArena, because simply turning off flight should be enough. It is
likely that the flySpeed tag was originally included to cull "cheaters"
who somehow managed to activate flight in the arena anyway, but this
isn't really MobArena's responsibility and can very probably be handled
by other means of cheat prevention in WorldGuard regions or the like.
By not touching the flySpeed tag, it makes it much easier for server
owners to recover from crashes where the leave steps aren't executed,
leaving players "locked in the air" when they try to fly.
Closes#509 since this "fix" was the reason that feature request was made.
Note that this doesn't make the arguments for commands case insensitive. Each command is still responsible for lowercasing their arguments if it makes sense for them to do so.
This closes#446.
Lowercasing the enchantment string before feeding it to the Bukkit API makes the enchantments a little more "copy/paste proof" when grabbing the uppercased names from the JavaDocs/Minecraft wiki.
Spectating is possible both during and before/after arena sessions. This means that an early return from the entity damage cancellation logic when the arena isn't running is going to allow damage to go through to spectators of non-running arenas, which means they can die. By simply removing the early return (and placing it in the one branch that actually requires it explicitly), spectators should no longer be able to take damage.
This fixes#502.
This changes how unbreakable items work in MobArena. It removes the legacy "repair logic" and replaces it with the item meta unbreakable flag. This approach should work all the same, except now if weapons and armor in class chests have special durability values, these are preserved in the cloning.
This should make MobArena compatible with plugins that depend on special durability values, such as QualityArmory.

Following the changes in 266104d0a1, this commit gathers the leave-then-join logic and handles it in one fell swoop when joining from the spectator area. This means that the timer will start, and when it runs out, the player leaves the current arena (if any), and then joins.
There should be no issues with overlapping timers or anything like that, since the lookup happens when the time is up, not before the timer is started.
Commit 924a419b47 made it impossible to join an arena from a spectator area because the playerLeave method call in JoinCommand was removed. The call is re-introduced in this commit along with similar logic in InvokesSignAction. This means that a spectating player can now join arenas as if they weren't spectating, rather than having to first leave the arena they are spectating.
This commit changes how MASpawnThread is started. Instead of simply scheduling a task and letting it run whenever, we now explicitly tell it to stop when the arena ends. This matters, because if the scheduled task does not get cancelled, it will run at the scheduled time. MASpawnThread's run() method has an early return to stop whenever the arena isn't running, but with unlucky timing, it's possible to start a new arena session before the task runs again, meaning the same MASpawnThread keeps scheduling itself on the previous scheduling loop.
Instead of this whacky approach, we now specifically have MASpawnThread track its own BukkitTask. Upon arena start, we instantiate a new MASpawnThread and call its start() method, which in turn schedules itself and stores a reference to the associated BukkitTask. Upon arena end, we call the MASpawnThread's stop() method, which explicitly calls the BukkitTask's cancel() method, effectively stopping/unscheduling the task.
This fixes the (very) long-standing "double wave spawner" bug that we haven't been able to reproduce for so long. Hooray!
This setting was removed a long time ago, likely by "happy mistake" in a larger refactoring.
When enabled, players are granted any collected experience during the arena session as a reward when they die or reach the final wave of the arena. Note that deliberately leaving the arena is not included here, because "leaving" an arena is a highly ambiguous and conditional concept at the time of this commit. Figuring out when and how the experience reward should be added is complicated, and unless someone puts in a request for it, I think it's enough that the "legitimate" reasons for getting the experience (honorable death and reaching the final wave) are covered.
Closes#485
It turns out that experience in Minecraft is split out on a couple of different variables, and they are only loosely coupled.
Total experience, level, and level progress are three completely different variables that can be manipulated individually. This means that while 10 experience points from level 0 should bring you up to level 1 with a third of the experience bar full (level 0 to 1 takes 7 points, level 1 to 2 takes 9 points), simply setting the total points value to 10 won't automatically level you up. Using the Player#giveExp(int) method will, however, work this way.
This commit adds an event handler for the PlayerArmorStandManipulateEvent and cancels it if the arena protection is on, we aren't in edit mode, and the region contains the armor stand. The same logic applies to the armor stand damage event.
This commit re-implements and rearranges a lot of the logic in the main plugin class. It also removes the ConfigCommand class and moves its functionality into the CommandHandler to allow for reloads to be a bit more special than normal commands.
In the refactoring of the main class, the startup logic is broken up into two phases, setup and (re)load:
- In the setup phase, we create the data folder, and the command handler, config serializer(s), plugin integrations, boss abilities, the global event listener, and metrics are initialized. The ArenaMaster is instantiated, but it isn't initialized. These are things that need to be set up just once and don't change on reloads.
- In the (re)load phase, the config-file is loaded from disk, the global messenger is instantiated, the arena master is initialized (loads settings, classes, and arenas), the announcements file is loaded from disk along with the sign data/templates. These are things that we want to be reloadable.
If anything goes wrong during these phases, we store the exception thrown. This puts MobArena into a state where it prints the exception message to anyone who types a non-reload MobArena command to bring attention to the error so it can be fixed.
This commit is a full sweep across the WaveParser. It introduces the ConfigError exception to the WaveParser and throws it whenever something isn't right. There's quite a lot of stuff going on, but in overall:
- Errors are thrown rather than null values being returned
- Defaults are picked in lieu of explicit values when they "make sense"
- Most list-type values can now be either the default comma-separated string or a string list
Common nodes:
- Spawnpoints can now be a string list
Default waves:
- Missing or empty monsters map throws an error
- Missing wave growth defaults to medium
- Invalid wave growth throws an error
Special waves:
- Missing or empty monsters map throws an error
Swarm waves:
- Missing or empty monster node throws an error
- Missing swarm amount defaults to low
- Invalid swarm amount throws an error
Supply waves:
- Missing or empty monsters map throws an error
- Missing or empty drops node throws an error
- Invalid drop throws an error
- Drops can now be a string list
Upgrade waves:
- Missing or empty upgrades map throws an error
Boss waves:
- Missing or empty monster node throws an error
- Missing or empty boss health defaults to medium
- Invalid boss health throws an error
- Invalid ability throws an error
- Invalid drop throws an error
- Abilities and drops can now be string lists
This commit changes how the ThingParser is used throughout the code base. Instead of blindly filtering out null values, we're now throwing a new InvalidThingInputString exception. This exception is caught in an outer scope that has more context. The exception is then unwrapped and rethrown as a ConfigError with the additional context. In the outermost scope of (re)loading the config-file, the ConfigError is caught and printed, and then (re)loading stops gracefully.
We still need a proper way to handle loads/reloads consistently to get rid of the default command usage message, but this is a good step towards better usability in the face of user errors.
Fixes#478
This commit adds a new per-arena setting, join-interrupt-timer, which, when set to a positive number, will introduce a delay to the join and spec commands. During this delay, if the player takes damage or moves more than one block's distance, the command will be interrupted.
Closes#482
This, along with a (currently not committed) script to generate github releases and Spigot/DBO formatted release notes from this changelog, should reduce some of the friction associated with new releases.
This commit adds a new per-arena config-file setting, next-wave-delay. When a new wave is about to spawn, a positive next-wave-delay value will cause the spawning of the wave to be delayed by that amount of seconds, similar to how first-wave-delay delays the spawning of the first wave.
By moving all of the actual spawning logic into a new method and simply referencing that as a Runnable, we can avoid having to set weird boolean flags and re-scheduling the MASpawnThread itself.
Closes#449
The autogenerated arenas are backed up in a file that isn't valid in 1.13. It's also buggy, inducing a false sense of safety. Instead of trying to hack it together for 1.13, let's remove it and see if we can't live without it.
This semi-reverts part of the change in e484583b7e.
We're now specifically denying the use of items if there are any. This doesn't cancel the interact event, but just prevents stuff like potion consumption.
The block fade event is called when a block fades from one state to another, such as when snow melts and becomes air, or ice melts and becomes water. Cancelling it solves the issue of snow and ice melting in arenas.
Fixes#249.
Originally, the right click ban was introduced to prevent issues with people blowing themselves and each other up in the lobby. The right click ban only solves this issue sometimes, so it isn't really very effective.
By removing the right click ban, it becomes possible to activate redstone stuff like buttons and levers in the lobby.
Fixes#431.
The flag is almost always set to true, and when it isn't, it's either because people don't know that they have to set it, or because they only give one upgrade per class and thus don't feel the effect of it.
This is not the proper way to solve this issue, but the refactoring needed to move the responsibility of class chest search somewhere else is a bit too much for a bug hunt.
This introduces state in the ScoreboardManager for keeping track of the scoreboards that players have before the arena session starts, if any. Upon leaving, the scoreboards are restored.
Ideally, this change should be re-implemented as a Step of the join/leave process, but that would require opening up Arena or ScoreboardManager in ways that would probably be best handled in a rewrite of the scoreboards, so we'll leave it in ScoreboardManager for now.
Fixes#366
A new section in global-settings called pet-items is used to define pet item transformation items. By default, bones are transformed into wolves, but the item type can now be changed to support using actual bones in classes.
This refactors the pet spawning into its own class to reduce some of the massive responsibility of ArenaImpl.
This closes#467
In this commit, the ItemParser's behavior changes from one that requires or encourages numeric IDs for everything to one that discourages it by logging a warning that suggests using a string instead of a numeric value.
While this doesn't actually make things that much better for updating to Minecraft 1.13, the "ID nagging" hopefully increases awareness about the upcoming breaking changes.
Fixes#382
This follows from the removal of the set class command being removed and the cascading removal of the methods in ArenaMasterImpl that referenced the parseString methods in ItemParser.
Similar to a88556771f.
This specific change may stir the pot a bit, since some people may rely on the set command. However, class chests solve a lot of the problems that the initial command set out to tackle, and we can probably do better in a rewrite of the command if it's missed anyway.
The removed commands render a few methods in ArenaMaster obsolete.
These commands solve a very, very specific problem that it's safe to assume nobody has. It's safe to assume that most config editing happens in the actual config-file, and changing class permissions is probably one of the last things people would expect to find a command for.
Removing these commands renders some methods in ArenaMaster and ArenaClass obsolete.
Instead of the obscure error thrown from ArenaClass when the SHIELD enum value on Material isn't found, MobArena throws its own, more human-friendly error.
Fixes#469
When the arena ends, the MonsterManager is cleared, which means that all references to health bars are lost. Before this, we remove all players from any boss bars to make sure that the boss bars don't stick to players upon dying.
Fixes#473
This changes the upgrade waves from the local Upgrade interface to the Thing interface. This means that all Things can now be used in upgrade waves, including commands, money, potion effects, and permissions.
Unfortunately, the weapons upgrade/replace functionality has been gutted as a result of the Things API not supporting it. We could add it back in later down the road, but for now let's just see if it causes anyone any inconvenience.
Closes#468
This replaces the Map<String, Boolean> approach in ArenaClass with a List<Thing> approach. This greatly simplifies how per-class permissions are handled.
This commit introduces the PermissionThing and associated parser. The parser determines the value (grant/revoke) of the permission by looking at the first character of the input string - if it is a minus (-) or caret (^), the value is false (revoke), otherwise it is true (grant). To distinguish permissions from other things, the parser requires a prefix of "perm:".
This removes the map of attachments in ArenaImpl and makes the permissions "replacement" happen via the Bukkit API's PermissionAttachmentInfo. Bukkit already keeps track of which attachments we've added to a player, so removing them is just a matter of looping through and finding those. This reduces the coupling between the Arena interface and UpgradeWave (which is the only interface that used the methods removed from the Arena interface).
The goal with these specific metrics is to figure out if some of the arena settings can be removed. If everyone uses the same values for these settings, there is no point in having the added complexity in the code.
Three different types of health bars are implemented behind a basic Strategy Pattern. A new per-arena setting, boss-health-bar, can be used to configure which one of the three types (if any) of health bar should be used for bosses in the given arena:
- `boss-bar` creates a boss bar at the top of the screen as if the players were fighting an ender dragon or a wither.
- `title` uses the Chapters/Titles API in Bukkit to display the health of the boss as a "subtitle" whenever it takes damage.
- `name` sets the entitiy's health along with an optional custom name above the entity's head.
The announcements file loading method is renamed to indicate that it's also meant for re-loading, and the access modifier is changed from private to package-private to allow ArenaMasterImpl to call it.
Closes#462
The existing issue template tries to cover everything, and as a result it is a bit overwhelming. Using multiple issue templates trims the noise when you know what kind of issue you're submitting.
It's just UTF-8, Maven. No need to throw warnings all over the place...
This commit fixes some of the source encoding warnings Maven would print during compilation.
This commit introduces the PotionEffectThing and associated parser. The parser simply delegates to the existing PotionEffectParser utility class the same way the ItemStackThing parser does it. To distinguish potion effects from other things, the parser requires a prefix of "effect:".
As with the initial Thing API commit, this commit also adds an overload to the existing parser class to avoid spamming the console with meaningless warnings.
Boss waves already support potion effects, but with this commit, the potions node moves up as a common node, so all waves that spawn monsters (all but upgrade waves) can now spawn those monsters with a list of potion effects applied to them. It's not possible to give certain potion effects to specific monster types. All monsters get all the effects listed in the node.
Because we aren't actually giving potions but potion effects, the node is renamed from "potions" to "effects". However, to preserve backwards compatibility, both names are supported in this commit.
Closes#453
The ability to execute commands by hitting signs is already implemented by other plugins, but by creating built-in support for such signs, it's possible to leverage information about the plugin and its current state. This implementation allows for displaying live information about player counts, waves, etc. on the signs in addition to tying actions to them.
Customizable templates defined in the new signs.yml config-file can be bound to signs during the in-game sign creation, and users can define state-specific templates that change based on whether an arena is completely idle, has players in the lobby, or is running and in full swing.
Sign data is stored in data/signs.data as a YAML-formatted file that shouldn't be modified directly, effectively separating configuration (templates in signs.yml) and data (coordinates and parameters in signs.data).
Closes#385
This commit makes it possible for mounted players to dismount. Upon dismounting, the horse AI is set to false to prevent it from moving around. Players attempting to mount an available horse will be thrown off unless they actually own the horse. The owners are free to remount when they want.
