getDistance() Function
Note: This function can only be used in a Trusted Macro
• Introduced in version 1.3b51
Returns the distance between two tokens or objects.
Usage
getDistance(target)
getDistance(target, units)
getDistance(target, units, source)
getDistance(target, units, source, metric)
Parameters
target
- The id of the token that the distance is measured to.units
- If set tofalse
(0
), the distance is given in cells, otherwise the default is to return the distance in Distance Per Cell units.source
- The id of the token to measure the distance from, the 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).
Example
To get the distance from the current token to the Altar.
[h: dist = getDistance("Altar")]
To get the distance between the Altar and the Sacrifice in the number of squares or hexes.
[h: dist = getDistance("Altar", 0, "Sacrifice")]
To get the distance between the Altar and the Sacrifice in map distance units.
[h: dist = getDistance("Altar", 1, "Sacrifice")]
To get the straight line distance between the Altar and the Sacrifice.
[h: dist = getDistance("Altar", 1, "Sacrifice", "NO_GRID")]
