Negative yaw values are considered valid in minecraft.
UtilShapes doesn't correctly handle negative yaw values
(throws an ArrayIndexOutOfBoundsException) so whenever
a player is facing east they're unable to activate Frost
Barrier.
This commit fixes the issue by allowing UtilShapes to take
negative values.
Currently players are unable to drop items if the held item
slot is below 5. This works fine when dropping items simply
by pressing q, but it often interferes with players dropping
items from an open inventory. This commit changes the check
to iterate over the first five slots and only cancel the event
if they're dropping one of them.
When using blink, players are teleported away from other players
within a one block radius of them. However, if a player happens
to have the exact same position(only can occur when a player is
spectating them), division by 0 occurs, resulting in the player
being teleported to NaN, as any operation with NaN is also NaN.
To fix this, Blink now ignores players in Spectator mode. This
change could also address the hypothetical scenario where a
spectator is within the one block radius and results in a blinking
player getting teleported in a weird direction.
This adds a system whereby plugins can associate metadata with individual
damage events and then retrieve that metadata later from the CombatLog.
One example use case for this is Minestrike. Players are rewarded according
to the weapon that they used to kill another player, however the weapons
are frequently renamed. Minestrike can now associate a "gunType" key
to the name of the weapon used to kill the player, regardless of the skin
that the gun currently has applied to it.
While the name of the gold items is "Golden X", the
name of the material is "GOLD X" resulting in gold items
providing no protective benefit other than the default
vanilla protection(in the case of there being only gold
armor).
