vectorFromTo

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.

Syntax

vector1 vectorFromTo vector2

Parameters:

• vector1: Vector3D or Vector2D - 3D or Arma 3 v2.00 2D vector (z coordinate is defaulted to 0)
• vector2: Vector3D or Vector2D - 3D or Arma 3 v2.00 2D vector (z coordinate is defaulted to 0)

Returns: Vector3D

Examples

Example 1

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