General information
Location
The character's absolute position is given by the command
/loc
which returns information in the form
Your position: x,y,z:X,Y=M
where
| values | meaning | range |
|---|---|---|
| M | map ID | Only map 65 is in use. |
| X,Y | section coordinates within map | -127..127 |
| x,y,z | pixel offsets from top-left of section | 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. |
Cell
Visualisation of a cell. The yellow area shows its lower extent.
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. Similarly, placed blocks are owned by the cell's owner; no other player can remove them.
The top left corner of a cell is registered to x and y pixel offsets that are multiples of 16.
Section
A 16x16 cell area identified by the same coordinates. See also, Geography.
Note: A section is also known as a "region" in abstract terms. The character-relative land area of this unit is however far too small to correspond to a region in the geographical sense, being more comparable to a section of real estate in size.
In contexts where character-relative scales and gameplay are relevant, the term "section" is used.
Length
Span
The length of a cell's horizontal edge. Graphically, 16 pixels.
Step
The height of a half-block as well as the height difference a character can climb by walking. It is the basic vertical unit applicable to construction. Graphically, 8 pixels.
Furlong
An imprecise unit of distance defined for convenience as a section difference of 10 in whichever of x or y directions the difference is greatest, ignoring finer divisions.
In contexts requiring precise lengths, it is equal to 160 spans.
