Creation methods:

• public Vector2 (double x, double y)
  Creates a [struct@Vector2] of coordinates x and y .

Methods:

• public void @set (double x, double y)
  Sets the X and Y coordinates of this to x and y.
• public void add (Vector2 vector1, Vector2 vector2)
• public Vector2 add_val (Vector2 vector2)
  This function is identical to vector2_add but the vectors are passed by value rather than by reference.
• public Vector2 cross_product (Vector2 vector2)
  Compute the cross product of two vectors.
• public Vector2 cross_product_val (Vector2 vector2)
  Identical to [method@Vector2.
• public double inner_product (Vector2 vector2)
  Computes the inner (dot) product of two 2D vectors.
• public double inner_product_val (Vector2 vector2)
  Identical to [method@Vector2.
• public double length ()
  Computes the length of a 2D vector.
• public double length_val ()
  Identical to [method@Vector2.
• public void mul (double factor)
  Multiplies each component of the this by factor.
• public Vector2 mul_val (double factor)
  Identical to [method@Vector2.
• public void neg ()
  Negates the this (i.
• public Vector2 neg_val ()
  Identical to [method@Vector2.
• public Vector2 normal ()
  Compute a normalized perpendicular vector to this
• public Vector2 normal_val ()
  Identical to [method@Vector2.
• public void normalize ()
  Normalizes the this so the length of the this is 1.0.
• public Vector2 normalize_val ()
  Identical to [method@Vector2.
• public void rotate (double alpha)
  Rotates the this counterclockwise by alpha radians.
• public Vector2 rotate_val (double alpha)
  Identical to [method@Vector2.
• public void sub (Vector2 vector1, Vector2 vector2)
• public Vector2 sub_val (Vector2 vector2)
  This function is identical to vector2_sub but the vectors are passed by value rather than by reference.

Fields:

• public double x
• public double y
