retrooper	ce2603549b	1.6.3 release, * LICENSE and copyright holder added in each file. If you are making a closed source product, all you need to do is make sure you aren't obfuscating my files. * BukkitMoveEvent deprecated, you may copy the event and recreate it on your end in your project, BukkitMoveEvent will most likely be removed in the next minor update. * CancellableEvent interface added, implemented in all built in events as they are all cancellable. * Asynchronous injecting and uninjecting is no longer done on the Netty threads, it is now done using java's Executor Service's threadpool * GitHub Wiki API usage Guide has been rewritten, should finished done today or in a few days	2020-09-01 16:53:31 +02:00

retrooper	33131f4fcd	Merge pull request #30 from NikV2/master Uninjections async are now configurable in the settings(can cause reload bugs), I’d rather have setIdentifier() deprecated for one patch version(1.6.1) then in 1.16.2 we remove it completely, basically if then user doesn’t set identifier to anything, we will generate a random one, low priority for injecting and uninjecting players in PacketEvents class.	2020-08-28 01:57:42 +02:00

retrooper	3ec44f72da	1.6 stable RELEASE	2020-08-27 19:02:37 +02:00
retrooper	3797c45d98	1.6 pre 6 Stable version, please use this and wait for 1.6 official release, more features coming ;) * Useless enums deleted: Gamemode.java, Hand.java * Enums that belong to wrappers have been refactored to be a "subclass" of that wrapper: EntityAnimationType.java, EntityUseAction.java, PlayerAction.java, PlayerDigType.java * Null pointer fixed in WrappedPacketInCustomPayload for 1.7.10 * Null pointer fixed in WrappedPacketInBlockPlace for 1.7.10 * Bug fixed in WrappedPacketInClientCommand for 1.7.10 * Bug fix in WrappedPacketInWindowClick.getWindowClickType() sometimes throwing a ArrayIndexOutOfBoundsException * WrappedPacketInEntityAction.PlayerAction missing enum constants for 1.7.10/1.8.x fixed, this enum should now be cross version safe, the RIDING_JUMP doesn't exist on newer versions, so accessing this enum should return START_RIDING_JUMP instead. This system for the enum should make 1.7/1.8 compatible with newer versions.	2020-08-26 14:38:39 +02:00

retrooper	94a1f67975	1.6 pre, with debugs, might not work! * All wrappers optimized, much faster with lots of caching * All wrappers have a function for loading, now wrappers load stuff when you call PacketEvents#load() * WrappedPacketOutKeepAlive is now sendable to players * WrappedPacketOutPosition wrapper created * WrappedPacketInWindowClick wrapper created	2020-08-25 17:30:19 +02:00
