getDistance

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 tokenRef)

getDistance(target tokenRef, units)

getDistance(target tokenRef, units, source tokenRef)

getDistance(target tokenRef, units, source tokenRef, metric)

Parameters

• target tokenRefEither the token id or Token Name of the token that the distance is measured to. - {{{2}}}
• units - If set to false(0), the distance is given in cells, otherwise the default is to return the distance in Distance Per Cell units.
• source tokenRef - Either the token id or Token Name 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 strings
  • NO_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).

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 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")]
