Description

Description:
Unit vector, equal to direction from vector1 to vector2. In other words this command produces normalised vector between given 2 points.
To get a non-normalised vector, use vectorDiff.
Groups:
Math - Vectors

Syntax

Syntax:
vector1 vectorFromTo vector2
Parameters:
vector1: Array - vector 3D or 2D (since Arma 3 logo black.png2.00, z coordinate is defaulted to 0)
vector2: Array - vector 3D or 2D (since Arma 3 logo black.png2.00, z coordinate is defaulted to 0)
Return Value:
Array

Examples

Example 1:
[1,2,3] vectorFromTo [4,5,6]; // is the same as vectorNormalized ([4,5,6] vectorDiff [1,2,3]);
