[Updated] BKCommonLib

For versions starting from 1.11.2+, please refer to https://www.spigotmc.org/resources/bkcommonlib.39590/

Welcome to BKCommonLib for Minecraft 1.8+. The builds released are still development builds, so bugs are expected. You can report bugs to me in the discussion Thread. Please use the format I provided there. Thank you![/B]

Some plugins using BKCommonLib may need to be updated to work with the new update. A lot of methods were changed due to the use of BlockPosition instead of the old x, y, z coord format!

Latest version: 1.70

Spigot: v1_9_R1 (MC 1.9.0)

Older builds available:

1.57 for MC1.8.6-1.8.9 (v1_8_R3)

Tekkit: Untested and thus unsupported, some features may not work as expected

Description
This utility library shares all the common code needs for various plugins, and having them in one library heavily reduces the amount of duplicated code. The featured utilities are varied, and whenever something is missing in Spigot, it is added in BKCommonLib. This is one of the reasons why it has become this large: there are simply a lot of things Spigot doesn't (want to) offer.

BKCommonLib has versioning on a per-plugin basis, so when a certain plugin needs version 2, and version 1 is installed, the server owner is automatically notified and the plugin is not enabled. This prevents the common mishaps with outdated BKCommonLib versions.

Other than utilities and services, this library offers a wide variety of reflection and user-friendly ways of accessing net.minecraft.server. If your plugin requires the use of the internals, but do not want to risk changing field and method names, you can depend on BKCommonLib to provide them for you. This allows you to remain compatible between CraftBukkit versions automatically, and reduces silent failure hazards.

Reasons for you to depend on this library

• You need to access Minecraft internals in your plugin, and Spigot has no API for it
• You are tired of re-uploading the same version over again because of the internals changing
• You want to work with Vector/math logic, or need to use other utility classes
• The YAML of Spigot dislikes you, and you want this to be easier
• You want to easily read and write configuration/data files
• You want easy access to data conversion utilities to convert user input
• You want to work with inventories in an advanced fashion
• You want to work with unique server events
• You want to alter entity behaviour (such as handling block collisions, custom movement, etc.)
• You want plugin messages/permissions to be configurable
• You want to work with (async)tasks without storing IDs
• You want to send and manipulate packets

Features

• General
  • PluginBase for easy access to metrics, permissions, localization and more
  • Permission defaults for storing the permissions a plugin uses
  • Localization for making the messages of a plugin configurable
• Utilities
  • General utilities for String, Logic, BlockFace and Math operations
  • Block utilities for Block-related operations (states, data, etc.)
  • ItemUtil for Inventory, Items and Item Transfer utilities
  • RecipeUtil to work with crafting and furnace recipes
  • Various Collections for auto-filtering, converting and even interpolation
• Data storage
  • Configuration API with nodes, headers and other goodies
  • NBT API designed after the configuration API
  • (Compressed)DataReader/DataWriter to read and write data from/to file
• Entities
  • CommonEntity implementations with added utilities
  • EntityController for altering entity behaviour
  • EntityNetworkController for altering entity network logic
• Services
  • Metrics for keeping track of plugin statistics
  • Conversion for conversions between all types of data
  • Events and Listeners to keep track of changes on the server
  • Packet services and API to keep track of packets
  • Task class for easier task scheduling
  • Scoreboard services to setup scoreboards without criteria
  • Tab View service to alter what is shown when players press tab (support for Tab View will be readded soon)

Getting started
To start using BKCommonLib, you have to include the jar file as a dependency (after adding BKCommonLib as dependency in the plugin.yml):

Like any dependency, keep the jar file somewhere on your computer and add it to your classpath. Nothing special here.

Dependencies BKCommonLib uses
BKCommonLib supports various other plugins and projects. Below all of these are listed:

• Vault - for permission plugin support
• ProtocolLib - to avoid packet listening conflicts
• Showcase(Standalone) - to ignore showcased items
• HyperConomy - to ignore shop items
• BleedingMobs - to ignore particles
• CGLib - for generating nms.Entity classes on-the-fly to supply Entity Controllers
• Objenesis - for generating classes without calling constructors (needed for various fixes inside class constructors)

Plugins that require BKCommonLib to be installed:

• TrainCarts

1. TC ActionBlocks
2. TC Hangrail
3. MinecraftTrainSimulator

• SignLink
  
• MyWorlds

Disclaimer
This plugin utilises Hidendra's plugin metrics system, which means that the following information is collected and sent to mcstats.org:

• A unique identifier
• The server's version of Java
• Whether the server is in offline or online mode
• The plugin's version
• The server's version
• The OS version/name and architecture
• The core count for the CPU
• The number of players online
• The Metrics version Opting out of this service can be done by editing plugins/Plugin Metrics/config.yml and changing opt-out to true.

License
This library uses an open license. Feel free to use whatever code you need from it, you do not have to ask me either. If you want me to add certain features, that is fine too. Everyone is allowed to use this Library as a dependency. I do recommend extending 'PluginBase' instead of 'JavaPlugin' then, as it allows you to automatically deal with the BKCommonLib versioning checks. See also: BKCommonLib license file

Compatibility
BKCommonLib supports ProtocolLib when it is enabled, but if it is not, the player connection is replaced resulting in several incompatibilities. To fix these incompatibility issues, install ProtocolLib next to BKCommonLib. This can not be stressed enough. When incompatibility occurs, BKCommonLib will notify you in the console and will disable itself.

Metrics
This plugin sends server count and dependency statistics to MCStats.org . You can (globally) opt out in the PluginMetrics/config.yml file.
