Function perpInto

  • Sets the elements of the 2D vector b so it becomes perpendicular to the 2D vector a.

    The direction of b with respect to a will be "to the right", i.e. rotated 90 degrees clockwise

    Parameters

    • a: Vec2

      a 2-element vector object

    • b: Vec2

      a 2-element vector in which to store the result

    Returns Vec2

    b as a vector perpendicular to a
