Rect2
=====

2D axis-aligned bounding box.

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

``Rect2`` consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.

It uses floating-point coordinates.

The 3D counterpart to ``Rect2`` is :ref:`AABB<class_AABB>`.

Property Descriptions
---------------------

.. _class_Rect2_property_end:

- :ref:`Vector2<class_Vector2>` **end**

+-----------+---------------------+
| *Default* | ``Vector2( 0, 0 )`` |
+-----------+---------------------+

Ending corner. This is calculated as ``position + size``. Setting this value will change the size.

----

.. _class_Rect2_property_position:

- :ref:`Vector2<class_Vector2>` **position**

+-----------+---------------------+
| *Default* | ``Vector2( 0, 0 )`` |
+-----------+---------------------+

Beginning corner. Typically has values lower than :ref:`end<class_Rect2_property_end>`.

----

.. _class_Rect2_property_size:

- :ref:`Vector2<class_Vector2>` **size**

+-----------+---------------------+
| *Default* | ``Vector2( 0, 0 )`` |
+-----------+---------------------+

Size from :ref:`position<class_Rect2_property_position>` to :ref:`end<class_Rect2_property_end>`. Typically, all components are positive.

If the size is negative, you can use :ref:`abs<class_Rect2_method_abs>` to fix it.

Method Descriptions
-------------------

.. _class_Rect2_method_Rect2:

- :ref:`Rect2<class_Rect2>` **Rect2** **(** :ref:`Vector2<class_Vector2>` position, :ref:`Vector2<class_Vector2>` size **)**

Constructs a ``Rect2`` by position and size.

----

- :ref:`Rect2<class_Rect2>` **Rect2** **(** :ref:`float<class_float>` x, :ref:`float<class_float>` y, :ref:`float<class_float>` width, :ref:`float<class_float>` height **)**

Constructs a ``Rect2`` by x, y, width, and height.

----

.. _class_Rect2_method_abs:

- :ref:`Rect2<class_Rect2>` **abs** **(** **)**

Returns a ``Rect2`` with equivalent position and area, modified so that the top-left corner is the origin and ``width`` and ``height`` are positive.

----

.. _class_Rect2_method_clip:

- :ref:`Rect2<class_Rect2>` **clip** **(** :ref:`Rect2<class_Rect2>` b **)**

Returns the intersection of this ``Rect2`` and b.

----

.. _class_Rect2_method_encloses:

- :ref:`bool<class_bool>` **encloses** **(** :ref:`Rect2<class_Rect2>` b **)**

Returns ``true`` if this ``Rect2`` completely encloses another one.

----

.. _class_Rect2_method_expand:

- :ref:`Rect2<class_Rect2>` **expand** **(** :ref:`Vector2<class_Vector2>` to **)**

Returns this ``Rect2`` expanded to include a given point.

----

.. _class_Rect2_method_get_area:

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

Returns the area of the ``Rect2``.

----

.. _class_Rect2_method_grow:

- :ref:`Rect2<class_Rect2>` **grow** **(** :ref:`float<class_float>` by **)**

Returns a copy of the ``Rect2`` grown a given amount of units towards all the sides.

----

.. _class_Rect2_method_grow_individual:

- :ref:`Rect2<class_Rect2>` **grow_individual** **(** :ref:`float<class_float>` left, :ref:`float<class_float>` top, :ref:`float<class_float>` right, :ref:`float<class_float>`  bottom **)**

Returns a copy of the ``Rect2`` grown a given amount of units towards each direction individually.

----

.. _class_Rect2_method_grow_margin:

- :ref:`Rect2<class_Rect2>` **grow_margin** **(** :ref:`int<class_int>` margin, :ref:`float<class_float>` by **)**

Returns a copy of the ``Rect2`` grown a given amount of units towards the :ref:`Margin<enum_@GlobalScope_Margin>` direction.

----

.. _class_Rect2_method_has_no_area:

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

Returns ``true`` if the ``Rect2`` is flat or empty.

----

.. _class_Rect2_method_has_point:

- :ref:`bool<class_bool>` **has_point** **(** :ref:`Vector2<class_Vector2>` point **)**

Returns ``true`` if the ``Rect2`` contains a point.

----

.. _class_Rect2_method_intersects:

- :ref:`bool<class_bool>` **intersects** **(** :ref:`Rect2<class_Rect2>` b, :ref:`bool<class_bool>` include_borders=false **)**

Returns ``true`` if the ``Rect2`` overlaps with ``b`` (i.e. they have at least one point in common).

If ``include_borders`` is ``true``, they will also be considered overlapping if their borders touch, even without intersection.

----

.. _class_Rect2_method_is_equal_approx:

- :ref:`bool<class_bool>` **is_equal_approx** **(** :ref:`Rect2<class_Rect2>` rect **)**

Returns ``true`` if this ``Rect2`` and ``rect`` are approximately equal, by calling ``is_equal_approx`` on each component.

----

.. _class_Rect2_method_merge:

- :ref:`Rect2<class_Rect2>` **merge** **(** :ref:`Rect2<class_Rect2>` b **)**

Returns a larger ``Rect2`` that contains this ``Rect2`` and ``b``.
