The character's absolute position is given by the command
which returns information in the form
Your position: x,y,z:X,Y=M
|M||map ID||Only maps 65 and map 66 are in use.|
|X,Y||region coordinates within map||-127..127|
|x,y,z||pixel offsets from top-left of region||x,y are in the range 0..255.
z is a non-negative integer corresponding to the elevation above ground level on which the character stands. It is typically a multiple of 8, which is the height of a half-block.
An absolutely positioned square column corresponding to the horizontal area in which a block can be placed, vertically extended to the map limits.
It is the basic unit of land possession; no more than one player can place blocks in the same cell unless within a town set up to allow it.
The top left corner of a cell is registered to x and y pixel offsets that are multiples of 16.
A 16x16 cell area identified by the same coordinates. See also, Geography.
The length of a cell's horizontal edge. Graphically, 16 pixels.
The height of a half-tile as well as the height difference a character can climb by walking. It is the basic vertical unit applicable to construction. Graphically, 8 pixels.
Note: A half-step is the smallest vertical unit that can be used precisely in-game, requiring the use of low tables or signs.
Quarter-step differences are possible only by using a townstone or player character.
These units have no broad application or acceptance, but may serve as useful alternatives at different scales or when writing fiction.
An imprecise unit of distance defined for convenience as a region difference of 10 in whichever of x or y directions the difference is greatest, ignoring finer divisions.
It is approximately 30 seconds walk on open ground.
In contexts requiring precise lengths, it is equal to 160 spans.
