Data types
A list of data types.
String
Any single word (whitespace at the beginning and end is ignored)
Examples:
hi
ThePython10110
better_commands
Long string
Any text (whitespace at the beginnning and end is ignored). Long strings are always the last argument in a command.
Examples:
example
another example
12983 plus eighty-nine = thirteen thousand and 72
Number
Any positive or negative number from -99,999,999,999,999 (negative 100 trillion + 1) to 100,000,000,000,000. (100 trillion)
Examples:
1
3.141592
-65535
Range
Either a number or values in the format [min]..[max]. Only one of [min] and [max] is required. Ranges are inclusive.
Examples:
6 (matches exactly 6)
3..5 (matches any number between 3 and 5, inclusive)
-293.5.. (matches any number greater than or equal to -293.5
...4 (matches any number less than or equal to .4)
1..-1 (matches no numbers, since no numbers are >= 1 but <= -1)
Boolean
Either true or false.
Position
A position is a set of three values intended to be used as x, y, and z coordinates (in that order).
Axes:
North: +Z (note that in ACOVG, north and south are reversed)
South: -Z
East: +X
West: -X
Up: +Y
Down: -Y
There are three possible value types that can be used as coordinates:
Absolute coordinates (numbers)
Absolute coordinates are used to specify an exact position in the world. They are just numbers.
Examples
1 50 7 means the position {x=1, y=50, z=7}.
-23.52 38.8 0 means the position {x=-23.52, y=38.8, z=0}
Relative coordinates (tilde notation)
Relative coordinates are used to specify a coordinate relative to where the command is executed. Relative coordinates are preceded by a tilde (~). You can combine relative coordinates with absolute coordinates.
Examples
~ ~5 ~ means the position 5 nodes above the execution position.
~-2 ~ 25 means the position 2 nodes in the -X direction from the execution position, with the Z coordinate replaced with 25. At {x=3, y=5, z=-3.5}, this would evaluate to {x=1, y=5, z=25}.
Local coordinates (caret notation)
Local coordinates are used to specify a coordinate relative to the execution position and rotation. It's similar to relative coordinates, except the execution rotation is treated as the Z-axis. Local coordinates are preceded with a caret (^). You cannot combine local coordinates with absolute or relative coordinates.
Examples
^ ^ ^5 Five nodes "forward"
^ ^-5 ^ Five nodes "down"
^-2 ^ ^ Two nodes "left"
Rotation
One or two values, intended to be used as yaw (left/right rotation) and sometimes pitch (up/down rotation). Values are in degrees, and support tilde (relative) notation.
Directions
North: Yaw = 0
West: Yaw = 90
South: Yaw = 180
East: Yaw = 270
Up: Pitch = 90 (maximum for players is 89.5)
Down: Pitch = -90 (minimum for players is -89.5)
Examples
45: Northwest
~45: 45 degrees counterclockwise from the current direction
180 -90: Facing south and down
~1 ~-1 (1 degree counterclockwise and one degree up from the current direction)
Selector
See Target Selectors.
Item/Node
An itemstring or item alias, with optional metadata in [square brackets]. Nodes support param1 and param2 being set this way.
Items can also be specified with a count and wear value, such as default:pick_wood 1 65535
Item Examples
default:dirt = dirt
dirt = dirt (alias)
dirt[color=green] = green dirt
dirt[color=green] 24 = 24 green dirt
default:pick_wood[color=green] 1 32768 = a green half-worn wooden pickaxe
Node Examples
default:dirt = dirt
default:water_flowing[param2=3] = flowing water (level 3)
