Transform2D

A 2×3 matrix representing a 2D transformation.

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 Vector2 values: x, y, and the origin.

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

Note

There are notable differences when using this API with C#. See Différences de l'API C# par rapport à GDScript for more information.

Constants

IDENTITY = Transform2D(1, 0, 0, 1, 0, 0)

The identity Transform2D with no translation, rotation or scaling applied. When applied to other data structures, IDENTITY performs no transformation.

FLIP_X = Transform2D(-1, 0, 0, 1, 0, 0)

The Transform2D that will flip something along the X axis.

FLIP_Y = Transform2D(1, 0, 0, -1, 0, 0)

The Transform2D that will flip something along the Y axis.


Property Descriptions

Vector2 origin = Vector2(0, 0)

The origin vector (column 2, the third column). Equivalent to array index 2. The origin vector represents translation.


Vector2 x = Vector2(1, 0)

The basis matrix's X vector (column 0). Equivalent to array index 0.


Vector2 y = Vector2(0, 1)

The basis matrix's Y vector (column 1). Equivalent to array index 1.


Constructor Descriptions

Transform2D Transform2D ( )

Constructs a default-initialized Transform2D set to IDENTITY.


Transform2D Transform2D ( Transform2D from )

Constructs a Transform2D as a copy of the given Transform2D.


Transform2D Transform2D ( float rotation, Vector2 position )

Constructs the transform from a given angle (in radians) and position.


Transform2D Transform2D ( float rotation, Vector2 scale, float skew, Vector2 position )

Constructs the transform from a given angle (in radians), scale, skew (in radians) and position.


Transform2D Transform2D ( Vector2 x_axis, Vector2 y_axis, Vector2 origin )

Constructs the transform from 3 Vector2 values representing x, y, and the origin (the three column vectors).
