Description

Description:
Returns normalized vector (unit vector, vectorMagnitude == 1) of given vector. If given vector is 0 result is a 0 vector as well.
Since Arma 3 logo black.png 2.14 any count of numbers is valid.
Before Arma 3 logo black.png 2.14, the first argument had to be vector 3D, or Arma 3 logo black.png 2.00 2D (Which still returned 3D result, with z coordinate defaulted to 0)
Groups:
Math - Vectors

Syntax

Syntax:
vectorNormalized vector
Parameters:
vector: Array of Numbers
Return Value:
Array

Examples

Example 1:
vectorNormalized [12345,7890,38383]; // [0.300481,0.192045,0.934254] vectorMagnitude [0.300481,0.192045,0.934254]; // 1
