getDistanceToXY

getDistanceToXY() Function

• Introduced in version 1.3b51

Gets the distance to a target grid cell.

Usage

<source lang="mtmacro" line> 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) </syntaxhighlight> 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 - 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 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).

Example

To get the distance from the current token to 10,10.

<source lang="mtmacro" line> [h: dist = getDistanceToXY(10, 10)] </syntaxhighlight>

To get the distance between the Altar and 10, 10 in the number of squares or hexes. <source lang="mtmacro" line> [h: dist = getDistanceToXY(10, 10, 0, "Altar")] </syntaxhighlight>

To get the distance between the Altar and 10, 10 in map distance units. <source lang="mtmacro" line> [h: dist = getDistanceToXY(10, 10, 1, "Altar")] </syntaxhighlight>

To get the straight line distance between the Altar and 10, 10. <source lang="mtmacro" line> [h: dist = getDistanceToXY(10, 10, 1, "Altar", "NO_GRID")]

</syntaxhighlight>
