Description
- Description:
- Returns Euclidean distance between two 3D vectors or two 3D positions.
- Groups:
- Math - Vectors
Syntax
- Syntax:
- vector1 vectorDistance vector2
- Parameters:
- vector1: Array in format [x,y,z] or Position3D or 2D (since Arma 3 v1.99.146539, z coordinate is defaulted to 0)
- vector2: Array in format [x,y,z] or Position3D or 2D (since Arma 3 v1.99.146539, z coordinate is defaulted to 0)
- Return Value:
- Number
Examples
- Example 1:
_euclideanDist = getPosASL player vectorDistance [0,0,0];- Example 2:
(getPosASL _a) vectorDistance (getPosASL _b); // same as (getPosATL _a) distance (getPosATL _b);

(ArmA3 1.22) Algorithm:
Vector1 = [x1,y1,z1]; Vector2 = [x2,y2,z2]; Result = sqrt ((x2 - x1) ^ 2 + (y2 - y1) ^ 2 + (z2 - z1) ^ 2);
