CommandsPlus

Reposted from here

The objective of CommandsPlus is to extract data from the results of running various commands. For example, teleporting an armor stand to a player gives us the player's coordinates and which way he's facing.

Methods

Code Select Expand

getPlayerPosition( playerName )Retrieves the position (x, y, z) of the specified player. Specifying something other than an online player's name will result in an error.

Code Select Expand

getPlayerRotation( playerName )Retrieves the rotation (about the vertical axis, about the horizantal axis) of the specified player. Again, specifying something other than an online player's name will result in an error.

Code Select Expand

getNearbyPlayers( nLimit )Retrieves a list of players within nLimit blocks of the computer. If nLimit is not specified, no radius will be used.

Code Select Expand

getGameruleValue( gamerule )Retrieves the value of a gamerule (eg "commandBlockOutput")

Note: this is sometimes inaccurate due to non-full blocks or entities.

Code Select Expand

{
[ dimension ] = { time = MEAN_TIME, tps = MEAN_TPS }
}

If there are any commands you'd like me to add, please comment below ;)
Updates:
1.1 - Added getObservedBlock and getFormattedBlockInfos, added second argument to getPlayerPosition, changed behavior of getNearbyPlayers when no limit specified.
1.2 - Added getForgeTPS()
1.25 - Removed second argument from getPlayerPosition, added caching. The data is only cached for 1 tick, so that if you use getObservedBlock and getPlayerPosition or getPlayerRotation, it won't teleport things more than it needs to.
1.3 - Added listScoreboardTeams, listScoreboardObjectives, listScoreboardPlayers, and listScoreboardTeamPlayers

PS: Apologies for wall of text, supposedly spoilers will be available in the future (@Yemmel)
