Description
- Description:
- Magnitude of a 3D vector.
- Groups:
- Math - Vectors
Syntax
- Syntax:
- vectorMagnitude vector
- Parameters:
- vector: Array - vector 3D or 2D (since Arma 3 v1.99.146539, z coordinate is defaulted to 0)

Examples
- Example 1:
_size = vectorMagnitude [0,3,4]; // returns 5- Example 2:
_speed = vectorMagnitude velocity player; // return velocity of player in m/s _speed = (vectorMagnitude velocity player) * 3.6; // return velocity of player in km/h _speed = (vectorMagnitude velocity player) * 2.23694; // return velocity of player in mph

(ArmA3 1.22) Algorithm:
Vector = [x,y,z]; Result = sqrt ((x ^ 2) + (y ^ 2) + (z ^ 2));It is recommended to use vectorMagnitude instead of BIS_fnc_magnitude.
