Member Variables
----------------

  .. _class_Vector2_x:

- :ref:`float<class_float>` **x** - X component of the vector.

  .. _class_Vector2_y:

- :ref:`float<class_float>` **y** - Y component of the vector.


Description
-----------

2-element structure that can be used to represent positions in 2d-space, or any other pair of numeric values.

Member Function Description
---------------------------

.. _class_Vector2_Vector2:

- :ref:`Vector2<class_vector2>` **Vector2** **(** :ref:`float<class_float>` x, :ref:`float<class_float>` y **)**

Constructs a new Vector2 from the given x and y.

.. _class_Vector2_abs:

- :ref:`Vector2<class_vector2>` **abs** **(** **)**

Returns a new vector with all components in absolute values (i.e. positive).

.. _class_Vector2_angle:

- :ref:`float<class_float>` **angle** **(** **)**

Returns the result of atan2 when called with the Vector's x and y as parameters (Math::atan2(x,y)).

Be aware that it therefore returns an angle oriented clockwise with regard to the (0, 1) unit vector, and not an angle oriented counter-clockwise with regard to the (1, 0) unit vector (which would be the typical trigonometric representation of the angle when calling Math::atan2(y,x)).

.. _class_Vector2_angle_to:

- :ref:`float<class_float>` **angle_to** **(** :ref:`Vector2<class_vector2>` to **)**

Returns the angle in radians between the two vectors.

.. _class_Vector2_angle_to_point:

- :ref:`float<class_float>` **angle_to_point** **(** :ref:`Vector2<class_vector2>` to **)**

Returns the angle in radians between the line connecting the two points and the x coordinate.

.. _class_Vector2_aspect:

- :ref:`float<class_float>` **aspect** **(** **)**

Returns the ratio of X to Y.

.. _class_Vector2_bounce:

- :ref:`Vector2<class_vector2>` **bounce** **(** :ref:`Vector2<class_vector2>` n **)**

Bounce returns the vector "bounced off" from the given plane, specified by its normal vector.

.. _class_Vector2_clamped:

- :ref:`Vector2<class_vector2>` **clamped** **(** :ref:`float<class_float>` length **)**

Returns the vector with a maximum length.

.. _class_Vector2_cubic_interpolate:

- :ref:`Vector2<class_vector2>` **cubic_interpolate** **(** :ref:`Vector2<class_vector2>` b, :ref:`Vector2<class_vector2>` pre_a, :ref:`Vector2<class_vector2>` post_b, :ref:`float<class_float>` t **)**

Cubicly interpolates between this Vector and "b", using "pre_a" and "post_b" as handles, and returning the result at position "t". "t" should be a float of 0.0-1.0, a percentage of how far along the interpolation is.

.. _class_Vector2_distance_squared_to:

- :ref:`float<class_float>` **distance_squared_to** **(** :ref:`Vector2<class_vector2>` to **)**

Returns the squared distance to vector "b". Prefer this function over "distance_to" if you need to sort vectors or need the squared distance for some formula.

.. _class_Vector2_distance_to:

- :ref:`float<class_float>` **distance_to** **(** :ref:`Vector2<class_vector2>` to **)**

Returns the distance to vector "b".

.. _class_Vector2_dot:

- :ref:`float<class_float>` **dot** **(** :ref:`Vector2<class_vector2>` with **)**

Returns the dot product with vector "b".

.. _class_Vector2_floor:

- :ref:`Vector2<class_vector2>` **floor** **(** **)**

Remove the fractional part of x and y.

.. _class_Vector2_is_normalized:

- :ref:`bool<class_bool>` **is_normalized** **(** **)**

Returns whether the vector is normalized or not.

.. _class_Vector2_length:

- :ref:`float<class_float>` **length** **(** **)**

Returns the length of the vector.

.. _class_Vector2_length_squared:

- :ref:`float<class_float>` **length_squared** **(** **)**

Returns the squared length of the vector. Prefer this function over "length" if you need to sort vectors or need the squared length for some formula.

.. _class_Vector2_linear_interpolate:

- :ref:`Vector2<class_vector2>` **linear_interpolate** **(** :ref:`Vector2<class_vector2>` b, :ref:`float<class_float>` t **)**

Returns the result of the linear interpolation between this vector and "b", by amount "t". "t" should be a float of 0.0-1.0, a percentage of how far along the interpolation is.

.. _class_Vector2_normalized:

- :ref:`Vector2<class_vector2>` **normalized** **(** **)**

Returns a normalized vector to unit length.

.. _class_Vector2_reflect:

- :ref:`Vector2<class_vector2>` **reflect** **(** :ref:`Vector2<class_vector2>` n **)**

Reflects the vector along the given plane, specified by its normal vector.

.. _class_Vector2_rotated:

- :ref:`Vector2<class_vector2>` **rotated** **(** :ref:`float<class_float>` phi **)**

Rotates the vector by "phi" radians.

.. _class_Vector2_slide:

- :ref:`Vector2<class_vector2>` **slide** **(** :ref:`Vector2<class_vector2>` n **)**

Slide returns the component of the vector along the given plane, specified by its normal vector.

.. _class_Vector2_snapped:

- :ref:`Vector2<class_vector2>` **snapped** **(** :ref:`Vector2<class_vector2>` by **)**

Snaps the vector to a grid with the given size.

.. _class_Vector2_tangent:

- :ref:`Vector2<class_vector2>` **tangent** **(** **)**

Returns a perpendicular vector.
