Transform2D
===========

A 2×3 matrix representing a 2D transformation.

.. rst-class:: classref-introduction-group

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

The **Transform2D** built-in :ref:`Variant<class_Variant>` type is a 2×3 `matrix <https://en.wikipedia.org/wiki/Matrix_(mathematics)>`__ representing a transformation in 2D space. It contains three :ref:`Vector2<class_Vector2>` values: :ref:`x<class_Transform2D_property_x>`, :ref:`y<class_Transform2D_property_y>`, and :ref:`origin<class_Transform2D_property_origin>`. Together, they can represent translation, rotation, scale, and skew.

The :ref:`x<class_Transform2D_property_x>` and :ref:`y<class_Transform2D_property_y>` axes form a 2×2 matrix, known as the transform's **basis**. The length of each axis (:ref:`Vector2.length<class_Vector2_method_length>`) influences the transform's scale, while the direction of all axes influence the rotation. Usually, both axes are perpendicular to one another. However, when you rotate one axis individually, the transform becomes skewed. Applying a skewed transform to a 2D sprite will make the sprite appear distorted.

For a general introduction, see the :doc:`Matrices and transforms <../tutorials/math/matrices_and_transforms>` tutorial.

\ **Note:** Unlike :ref:`Transform3D<class_Transform3D>`, there is no 2D equivalent to the :ref:`Basis<class_Basis>` type. All mentions of "basis" refer to the :ref:`x<class_Transform2D_property_x>` and :ref:`y<class_Transform2D_property_y>` components of **Transform2D**.

.. note::

	There are notable differences when using this API with C#. See :ref:`doc_c_sharp_differences` for more information.

Constants
---------

.. _class_Transform2D_constant_IDENTITY:

.. rst-class:: classref-constant

**IDENTITY** = ``Transform2D(1, 0, 0, 1, 0, 0)`` :ref:`🔗<class_Transform2D_constant_IDENTITY>`

The identity **Transform2D**. A transform with no translation, no rotation, and its scale being ``1``. When multiplied by another :ref:`Variant<class_Variant>` such as :ref:`Rect2<class_Rect2>` or another **Transform2D**, no transformation occurs. This means that:

- The :ref:`x<class_Transform2D_property_x>` points right (:ref:`Vector2.RIGHT<class_Vector2_constant_RIGHT>`);

- The :ref:`y<class_Transform2D_property_y>` points up (:ref:`Vector2.UP<class_Vector2_constant_UP>`).

::

    var transform = Transform2D.IDENTITY
    print("| X | Y | Origin")
    print("| %s | %s | %s" % [transform.x.x, transform.y.x, transform.origin.x])
    print("| %s | %s | %s" % [transform.x.y, transform.y.y, transform.origin.y])
    # Prints:
    # | X | Y | Origin
    # | 1 | 0 | 0
    # | 0 | 1 | 0

This is identical to creating :ref:`Transform2D<class_Transform2D_constructor_Transform2D>` without any parameters. This constant can be used to make your code clearer, and for consistency with C#.

.. _class_Transform2D_constant_FLIP_X:

.. rst-class:: classref-constant

**FLIP_X** = ``Transform2D(-1, 0, 0, 1, 0, 0)`` :ref:`🔗<class_Transform2D_constant_FLIP_X>`

When any transform is multiplied by :ref:`FLIP_X<class_Transform2D_constant_FLIP_X>`, it negates all components of the :ref:`x<class_Transform2D_property_x>` axis (the X column).

When :ref:`FLIP_X<class_Transform2D_constant_FLIP_X>` is multiplied by any basis, it negates the :ref:`Vector2.x<class_Vector2_property_x>` component of all axes (the X row).

.. _class_Transform2D_constant_FLIP_Y:

.. rst-class:: classref-constant

**FLIP_Y** = ``Transform2D(1, 0, 0, -1, 0, 0)`` :ref:`🔗<class_Transform2D_constant_FLIP_Y>`

When any transform is multiplied by :ref:`FLIP_Y<class_Transform2D_constant_FLIP_Y>`, it negates all components of the :ref:`y<class_Transform2D_property_y>` axis (the Y column).

When :ref:`FLIP_Y<class_Transform2D_constant_FLIP_Y>` is multiplied by any basis, it negates the :ref:`Vector2.y<class_Vector2_property_y>` component of all axes (the Y row).

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

.. _class_Transform2D_method_affine_inverse:

.. rst-class:: classref-method

:ref:`Transform2D<class_Transform2D>` **affine_inverse**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_affine_inverse>`

Returns the inverted version of this transform. Unlike :ref:`inverse<class_Transform2D_method_inverse>`, this method works with almost any basis, including non-uniform ones, but is slower. See also :ref:`inverse<class_Transform2D_method_inverse>`.

\ **Note:** For this method to return correctly, the transform's basis needs to have a determinant that is not exactly ``0`` (see :ref:`determinant<class_Transform2D_method_determinant>`).

.. rst-class:: classref-item-separator

----

.. _class_Transform2D_method_basis_xform:

.. rst-class:: classref-method

:ref:`Vector2<class_Vector2>` **basis_xform**\ (\ v\: :ref:`Vector2<class_Vector2>`\ ) |const| :ref:`🔗<class_Transform2D_method_basis_xform>`

Returns a copy of the ``v`` vector, transformed (multiplied) by the transform basis's matrix. Unlike the multiplication operator (``*``), this method ignores the :ref:`origin<class_Transform2D_property_origin>`.

.. rst-class:: classref-item-separator

----

.. _class_Transform2D_method_basis_xform_inv:

.. rst-class:: classref-method

:ref:`Vector2<class_Vector2>` **basis_xform_inv**\ (\ v\: :ref:`Vector2<class_Vector2>`\ ) |const| :ref:`🔗<class_Transform2D_method_basis_xform_inv>`

Returns a copy of the ``v`` vector, transformed (multiplied) by the inverse transform basis's matrix (see :ref:`inverse<class_Transform2D_method_inverse>`). This method ignores the :ref:`origin<class_Transform2D_property_origin>`.

\ **Note:** This method assumes that this transform's basis is *orthonormal* (see :ref:`orthonormalized<class_Transform2D_method_orthonormalized>`). If the basis is not orthonormal, ``transform.affine_inverse().basis_xform(vector)`` should be used instead (see :ref:`affine_inverse<class_Transform2D_method_affine_inverse>`).

.. rst-class:: classref-item-separator

----

.. _class_Transform2D_method_determinant:

.. rst-class:: classref-method

:ref:`float<class_float>` **determinant**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_determinant>`

Returns the `determinant <https://en.wikipedia.org/wiki/Determinant>`__ of this transform basis's matrix. For advanced math, this number can be used to determine a few attributes:

- If the determinant is exactly ``0``, the basis is not invertible (see :ref:`inverse<class_Transform2D_method_inverse>`).

- If the determinant is a negative number, the basis represents a negative scale.

\ **Note:** If the basis's scale is the same for every axis, its determinant is always that scale by the power of 2.

:ref:`Vector2<class_Vector2>` **get_origin**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_get_origin>`

.. rst-class:: classref-method

:ref:`float<class_float>` **get_rotation**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_get_rotation>`

Returns this transform's rotation (in radians). This is equivalent to :ref:`x<class_Transform2D_property_x>`'s angle (see :ref:`Vector2.angle<class_Vector2_method_angle>`).

.. rst-class:: classref-item-separator

.. _class_Transform2D_method_get_scale:

.. rst-class:: classref-method

:ref:`Vector2<class_Vector2>` **get_scale**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_get_scale>`

Returns the length of both :ref:`x<class_Transform2D_property_x>` and :ref:`y<class_Transform2D_property_y>`, as a :ref:`Vector2<class_Vector2>`. If this transform's basis is not skewed, this value is the scaling factor. It is not affected by rotation.

    )
    # Rotating the Transform2D in any way preserves its scale.
    my_transform = my_transform.rotated(TAU / 2)

Returns the result of the linear interpolation between this transform and ``xform`` by the given ``weight``.

\ **Note:** For this method to return correctly, the transform's basis needs to be *orthonormal* (see :ref:`orthonormalized<class_Transform2D_method_orthonormalized>`). That means, the basis should only represent a rotation. If it does not, use :ref:`affine_inverse<class_Transform2D_method_affine_inverse>` instead.

:ref:`bool<class_bool>` **is_conformal**\ (\ ) |const| :ref:`🔗<class_Transform2D_method_is_conformal>`

Returns ``true`` if this transform's basis is conformal. A conformal basis is both *orthogonal* (the axes are perpendicular to each other) and *uniform* (the axes share the same length). This method can be especially useful during physics calculations.

Returns a copy of this transform with its basis orthonormalized. An orthonormal basis is both *orthogonal* (the axes are perpendicular to each other) and *normalized* (the axes have a length of ``1``), which also means it can only represent rotation.
