This is the best way to get an entity when the world and its UUID are known.
It is faster than Server.getEntity(UUID) because it does not have to iterate all worlds
This fixes a CRITICAL missing part of the Bukkit API due to mistakes on upstream
refusing to implement the Sentient NPC baseclass of all NPC's.
Until now, the Bukkit API has not provided a way for accessing and setting
a non creature entities target.
Although Flying, Slime, Ambient, and Water mobs all supported targets internally,
you were unable to get/set it.
Now with the SentientNPC API and these API's moved down, every sentient NPC has
access to target data.
This event is called when an entity receives knockback by another entity. The knockback can be modified in the event. If the event is cancelled the entity is not knocked back.
Called when a player is firing a bow and the server is choosing an arrow to use.
Plugins can skip selection of certain arrows and control which is used.
Used to determine ACTUAL Living NPC's. Spigot mistakenly inversed the conditions for LivingEntity, and
used LivingEntity for Insentient Entities, and named the actual EntityLiving class EntityInsentient.
This should of all been inversed on the implementation side. To make matters worse, Spigot never
exposed the differentiator that there are entities with AI that are not sentient/alive such as
Armor stands and Players are the only things that do not implement the REAL EntityLiving class (named Insentient internally)
This interface lets you identify NPC entities capable of sentience, and able to move about and react to the world.
Redirects are in place (or will be shortly). This is mostly
housekeeping.
Maven repo URLs already redirect however we can't deploy through them.
Jenkins URLs do not currently redirect but will within 24 hours.
Also adds a Discord link to the README, because apparently that's what
people want.
Documentation will be updated and announcements made once all redirects
are in place, until then, consider this advanced notice.
Adds ability to control who receives it and who is the source/sender (vanish API)
the standard API is to send the packet to everyone in the world, which is ineffecient.
This adds a new Builder API which is much friendlier to use.
Fires an event anytime an enderman intends to teleport away from the player
You may cancel this, enabling ranged attacks to damage the enderman for example.
Resolves#1101
It is often difficult to diagnose new issues server admins get when
upgrading to a new server version because the only information they are
able to tell us regarding the server version they are running is
"latest". This commit attempts to mitigate this by keeping track of the
previous version of Paper they were running, which is then reported by
the `/version` or `/paper version` command. This gives us a better idea
of the commits included in the upgrade, which may help diagnose new
issues easier.
It was using a redirect, but apparently a small portion of systems,
networks, some mess, are having problems with that redirect.
Just use the direct link and skip the hassle.
In some enviroments, the channel limit set by spigot can cause issues,
e.g. servers which allow and support the usage of mod packs.
provide an optional flag to disable this check, at your own risk.
* Make the legacy ping handler more reliable
The Minecraft server often fails to respond to old ("legacy") pings
from old Minecraft versions using the protocol used before the switch
to Netty in Minecraft 1.7.
Due to packet fragmentation[1], we might not have all needed bytes
available when the LegacyPingHandler is called. In this case, it will
run into an error, remove the handler and continue using the modern
protocol.
This is unlikely to happen for the first two revisions of the legacy
ping protocol (used in Minecraft 1.5.x and older) since the request
consists of only one or two bytes, but happens frequently for the
last/third revision introduced in Minecraft 1.6.
It has much larger, variable packet sizes due to the inclusion of
the virtual host (the hostname/port used to connect to the server).
The solution[2] is simple: If we find more than two matching bytes,
we buffer the remaining bytes until we have enough to fully read and
respond to the request.

* Add legacy ping support to PaperServerListPingEvent
Add a new method to StatusClient check if the client is a legacy
client that does not support all of the features provided in the
event.
Some plugins (e.g. older builds of EssentialsX) assume that
ServerListPingEvent.getSampleText() returns a mutable copy of
the player sample list. This was the case until it was refactored
on top of the new API introduced in #980.
As a result, they may run into an error when trying to modify the
returned list directly. Modify getSampleText() to return a mutable
copy (a plain ArrayList) to mimic the old behavior.
Don't want to risk mutating players properties in server list (unlikely, but lets be proper)
and Skull also has a setter API, so that should be used too.
* Drop original implementation for old player sample API
* Add extended PaperServerListPingEvent
Add a new event that extends the original ServerListPingEvent
and allows full control of the response sent to the client.
* Implement deprecated player sample API
I mistakenly thought .complete() also checked for textures, which was not the case
So the logic was not working as desired.
Also some undesired logic paths lead to textures of the logging in player being dropped, forcing
us to always load the textures immediately again on login, leading to rate limits.
Everythings now good
the .complete() api now will default specify to also complete textures, but you may
pass false to it to skip loading textures.
Gets the unique ID of the player currently known as the specified player name
In Offline Mode, will return an Offline UUID
This is a more performant way to obtain a UUID for a name than loading an OfflinePlayer
This is faster if all you need is the UUID, as .getOwner() will cause
an OfflinePlayer to be loaded from disk.
This method is already implemented on the server, just needed to expose it.
- Lots of itemstack cloning removed. Only clone if the item is actually moved
- Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
- Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
- Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration
This is adds basic item meta for armor stands. It does not add all
possible metadata however.
There are armor, hand, and equipment types, as well as position data
that can also be added here. This initial implementation should serve as
a starting point for future additions in this area.
Fixes GH-559
Allows plugins to populate profile properties from local sources to avoid calls out to Mojang API
to fill in textures for example.
If Mojang API does need to be hit, event fire so you can get the results.
This is useful for implementing a ProfileCache for Player Skulls
This simply provides the base API to create the objects. Further commits will come that adds
adds usage of this API to existing GameProfile based API's, as well as new API's.
This event can be used for when you want to exclude a certain player
from triggering monster spawns on a server.
Also a highly more effecient way to blanket block spawns in a world
Adds an event to fire before an Entity is created, so that plugins that need to cancel
CreatureSpawnEvent can do so from this event instead.
Cancelling CreatureSpawnEvent rapidly causes a lot of garbage collection and CPU waste
as it's done after the Entity object has been fully created.
Mob Limiting plugins and blanket "ban this type of monster" plugins should use this event
instead and save a lot of server resources.
See: https://github.com/PaperMC/Paper/issues/917
This allows plugins that give players the ability to apply the experience
points to the Item Mending formula, which will repair an item instead
of giving the player experience points.
Both an API To standalone mend, and apply mending logic to .giveExp has been added.
Fired when the server is about to merge 2 experience orbs
Plugins can cancel this if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.
Any plugin still using this API will result in the server saving an inconsistent UUID to player data files,
which then triggers warnings such as "Tried to load unrecognized recipe: bukkit:9e5b92f5-e549-4f47-b0a8-9f89390ed77b removed now."
on the players login.
Plugin authors need to define a key to keep it consistent between server restarts.
Let plugins be able to control tab completion of commands and chat async.
This will be useful for frameworks like ACF so we can define async safe completion handlers,
and avoid going to main for tab completions.
Especially useful if you need to query a database in order to obtain the results for tab
completion, such as offline players.
Also adds isCommand and getLocation to the sync TabCompleteEvent
