getDistanceToXY() Function
• Introduced in version 1.3b51
Gets the distance to a target grid cell.
Usage
getDistanceToXY(x, y)
getDistanceToXY(x, y, units)
getDistanceToXY(x, y, units, source)
getDistanceToXY(x, y, units, source, metric)
getDistanceToXY(x, y, units, source, metric, pixels)
Parameters
x
- The X coordinate of the target grid cell.y
- The Y coordinate of the target grid cell.units
- If set tofalse
(0
), the distance is returned in cells. Default is returning Distance Per Cell units.source
- The id of the token to measure the distance from. Default is the current token.metric
- The movement metric to use which defaults to the movement metric in the users preferences, the metric can be one of the following stringsNO_GRID
- The grid is ignored and straight line distance between the tokens is returned.ONE_TWO_ONE
- First Diagonal movement costs 1, second 2, and so on (Square grid only).ONE_ONE_ONE
- Diagonal movement costs a single square (Square grid only).MANHATTAN
- Diagonal movement costs 2 (Square grid only).NO_DIAGONALS
- No diagonal movement is allowed (Square grid only).
pixel
- If set totrue
(1
), the X and Y refer to pixels. If set tofalse
(0
), they refer to a cell. Default tofalse
(0
).
Example
To get the distance from the current token to 10,10.
[h: dist = getDistanceToXY(10, 10)]
To get the distance between the Altar and 10, 10 in the number of squares or hexes.
[h: dist = getDistanceToXY(10, 10, 0, "Altar")]
To get the distance between the Altar and 10, 10 in map distance units.
[h: dist = getDistanceToXY(10, 10, 1, "Altar")]
To get the straight line distance between the Altar and 10, 10.
[h: dist = getDistanceToXY(10, 10, 1, "Altar", "NO_GRID")]
