Description

Description:
Returns object direction vector in world space ([x,y,z]).
⚠
The vector is not necessarily normalized. The magnitude of the vector will be the same as the object scale.
  • A unit facing North would return [0,1,0]
  • A unit facing East would return [1,0,0]
  • A unit facing South would return [0,-1,0]
  • A unit facing West would return [-1,0,0]
Groups:
Math - Vectors

Syntax

Syntax:
vectorDir object
Parameters:
object: Object
Return Value:
Array - format Vector3D

Examples

Example 1:
_dirVector = vectorDir _unit;
