Prior to this commit all /say command output would be a generic "[Server]"
prefixed line. This commit changes that by adding the source into the
message, such as a player. By doing this Bukkit more closely matches
vanilla behaviour and gives a more descriptive message to the client.
In vanilla, gamerules are global, across all worlds. Maps created for
vanilla that use command blocks expect this behavior, which is broken
when they are placed on a world that is not the default world (world #0).
This commit changes that by using the command block's current world when
executing the command, forcing the game rules executed to be executed in
the world the command block is currently in.
TimedRegisteredListener uses a reference to the first event fired. This
causes a memory leak in the server for any references that event has. This
changes TimedRegisteredListener to only store a reference to the class of
the event.
This change is intentionally a breaking change, as it is an obscure part
of the API. A non-breaking change would require the leak to be maintained
or an immediate update for any plugins using the method, as it would be an
indirect break.
A unit test is also included to check behavior of shared superclass
functionality.
When the minimum volume is being used because the distance is over a
threshold, the unit vector delta should be added to the player's
location, instead of where the command specified location.
This change makes the player's location the point of reference for
playing sounds when distance to volume scale is lower than minimum
specified volume.
The implementation is designed around having both a main scoreboard and
numberous plugin managed scoreboards that can be displayed to specific
players.
Plugin managed scoreboards are active so long as a reference is kept by a
plugin, or it has been registered as a player's active scoreboard. Objects
specific to a scoreboard remain active until unregistered (which remove a
reference to the owning scoreboard), but quickly fail if accessed
post-unregistration.
CommandMap contains a method that will auto-complete commands
appropriately. Before the first space, it searches for commands of which
the sender has permission. After the first space, it delegates to the
individual command.
Vanilla commands contain implementations to mimic vanilla
implementation. Exception would be give, that allows for name matching;
a feature we already allowed as part of the command is now supported for
auto-complete as well.
Plugin commands can get a tab completer set to delegate the completion
for. If no tab completer is set, it can check the executor to see if it
implements the tab completion interface. It will also attempt to chain
calls if null gets returned from these interfaces. Plugins also
implement the new TabCompleter interface, to add ease-of-use for plugin
developers, similar to the onCommand() method.
The default command implementation simply searches for player names.
To help facilitate command completion, a utility class was added with
two functions. One checks two strings, to see if the specified string
starts with (ignoring case) the second. The other method uses the first
to selectively copy elements from one collection to another.
