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
