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

A 2×3 matrix representing a 2D transformation.

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

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

A 2×3 matrix (2 rows, 3 columns) used for 2D linear transformations. It can represent transformations such as translation, rotation, and scaling. It consists of three :ref:`Vector2<class_Vector2>` values: :ref:`x<class_Transform2D_property_x>`, :ref:`y<class_Transform2D_property_y>`, and the :ref:`origin<class_Transform2D_property_origin>`.

For more information, read the "Matrices and transforms" documentation article.

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

.. _class_Transform2D_method_affine_inverse:

.. rst-class:: classref-method

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

Returns the inverse of the transform, under the assumption that the transformation is composed of rotation, scaling and translation.

----

.. _class_Transform2D_method_basis_xform:

.. rst-class:: classref-method

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

Returns a vector transformed (multiplied) by the basis matrix.

----

.. _class_Transform2D_method_basis_xform_inv:

.. rst-class:: classref-method

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

Operator Descriptions
---------------------

.. _class_Transform2D_operator_neq_Transform2D:

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator !=** **(** :ref:`Transform2D<class_Transform2D>` right **)**

Returns ``true`` if the transforms are not equal.

\ **Note:** Due to floating-point precision errors, consider using :ref:`is_equal_approx<class_Transform2D_method_is_equal_approx>` instead, which is more reliable.

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

.. _class_Transform2D_operator_mul_PackedVector2Array:

.. rst-class:: classref-operator

:ref:`PackedVector2Array<class_PackedVector2Array>` **operator *** **(** :ref:`PackedVector2Array<class_PackedVector2Array>` right **)**

Transforms (multiplies) each element of the :ref:`Vector2<class_Vector2>` array by the given **Transform2D** matrix.

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

----

.. _class_Transform2D_operator_mul_Rect2:

.. rst-class:: classref-operator

:ref:`Rect2<class_Rect2>` **operator *** **(** :ref:`Rect2<class_Rect2>` right **)**

Transforms (multiplies) the :ref:`Rect2<class_Rect2>` by the given **Transform2D** matrix.

.. _class_Transform2D_operator_mul_Transform2D:

.. rst-class:: classref-operator

:ref:`Transform2D<class_Transform2D>` **operator *** **(** :ref:`Transform2D<class_Transform2D>` right **)**

Composes these two transformation matrices by multiplying them together. This has the effect of transforming the second transform (the child) by the first transform (the parent).

.. _class_Transform2D_operator_mul_Vector2:

.. rst-class:: classref-operator

:ref:`Vector2<class_Vector2>` **operator *** **(** :ref:`Vector2<class_Vector2>` right **)**

Transforms (multiplies) the :ref:`Vector2<class_Vector2>` by the given **Transform2D** matrix.

.. _class_Transform2D_operator_mul_float:

.. rst-class:: classref-operator

:ref:`Transform2D<class_Transform2D>` **operator *** **(** :ref:`float<class_float>` right **)**

This operator multiplies all components of the **Transform2D**, including the origin vector, which scales it uniformly.

----

.. _class_Transform2D_operator_mul_int:

.. rst-class:: classref-operator

:ref:`Transform2D<class_Transform2D>` **operator *** **(** :ref:`int<class_int>` right **)**

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator ==** **(** :ref:`Transform2D<class_Transform2D>` right **)**

Returns ``true`` if the transforms are exactly equal.
