Description

Description:
distance2D.jpg

Returns a distance in meters between Objects, Positions or Locations.

⚠
If positions are supplied as arguments, the coordinates are treated as PositionAGL. If Position2D is supplied, z is assumed 0. If you need distance between two Position3D coordinates, use vectorDistance.
Groups:
Math - Geometry

Syntax 1

Syntax:
param1 distance param2
Parameters:
param1: Object or Array in format PositionAGL or Position2D
param2: Object or Array in format PositionAGL or Position2D
Return Value:
Number - distance in meters or 1e10 if distance cannot be calculated

Syntax 2

Syntax:
location1 distance location2
Parameters:
location1: Location or Array in format Position or Position2D
location2: Location or Array in format Position or Position2D
Return Value:
Number - distance in meters or 1e10 if distance cannot be calculated

Syntax 3

Syntax:
a distance b
Parameters:
a: Number
b: Number
Return Value:
Number - distance c calculated as c = sqrt(a * a + b * b);

Examples

Example 1:
_meters = player distance _object;
Example 2:
_meters = player distance [1,2,3];
Example 3:
_meters = [1,2,3] distance [4,5,6];
Example 4:
_meters = position player distance nearestLocation [position player, "hill"];

This returns the map distance, not the vector distance, [0,0,0] distance [0,0,1] can be >1 or <1, not exactly 1; unlike the vector math.

When objects are supplied as arguments, distance is calculated from their model center (object modelToWorld [0,0,0]), and not the position returned by getPos/ATL/ASL.
However, this is not relevant for units, as their model center matches their world position.
