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

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_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".
.. _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_floorf:
- :ref:`Vector2<class_vector2>` **floorf** **(** **)**
Remove the fractional part of x and y.
.. _class_Vector2_get_aspect:
- :ref:`float<class_float>` **get_aspect** **(** **)**
Returns the ratio of X to Y.
.. _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".
.. _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>` vec **)**
Like "slide", but reflects the Vector instead of continuing along the wall.
.. _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>` vec **)**
Slides the vector by the other 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.
