## General informationEdit

### LocationEdit

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 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. |

### CellEdit

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.

### RegionEdit

A 16x16 cell area identified by the same coordinates. See also, Geography.

## LengthEdit

### SpanEdit

The length of a cell's horizontal edge. Graphically, 16 pixels.

### StepEdit

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.

## Other UnitsEdit

These units have no broad application or acceptance, but may serve as useful alternatives at different scales or when writing fiction.

### FurlongEdit

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.
