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 tokenRef)
getDistanceToXY(x, y, units, source tokenRef, metric)
getDistanceToXY(x, y, units, source tokenRef, metric, pixels)

Parameters

  • x - The X coordinate of the target grid cell.
  • y - The Y coordinate of the target grid cell.
  • units - If set to false(0), the distance is returned in cells. Default is returning Distance Per Cell units.
  • source tokenRef - Either the token id or Token Name 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 strings
    • NO_GRID - The grid is ignored and straight line distance between the center of the token and the center of the cell 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 to true(1), the X and Y refer to pixels. If set to false(0), they refer to a cell. Default to false(0).
Token IDs are unique, but Token Names can be duplicated. Using Token Name when more than one token has the same name can produce unexpected results.

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")]
