Description

Description:

An object with its vectorDir, vectorUp and vectorSide (vectors not to scale)

Returns an object's direction vector in world space.

⚠

The vector is not necessarily normalized. The magnitude of the vector depends on the object's scale.

For an object facing one of the cardinal directions on perfectly flat ground (parallel to the XY-plane of the world space), vectorDir returns simple values:

[0, 1, 0] if the object is facing directly north
[1, 0, 0] if the object is facing directly east
[0, -1, 0] if the object is facing directly south
[-1, 0, 0] if the object is facing directly west
