Mat2D

Represents a 2D transformation matrix with components for scaling, rotation, shear, and translation.

Fields

xx

Represents a 2D transformation matrix with components for scaling, rotation, shear, and translation. The xx component of the matrix.

xy

The xy component of the matrix.

yx

The yx component of the matrix.

yy

The yy component of the matrix.

tx

Translation along the x-axis.

ty

Translation along the y-axis.

withTranslation

Creates a translation matrix from the given x and y values or from a Vector position.

withScale

Creates a scale matrix from the given x and y values or from a Vector.

withScaleAndTranslation

Creates a scale-and-translation matrix from numeric values or vectors.

Constructors

values

values

Creates a matrix using the specified components.

identity

identity

Returns the identity matrix.

withRotation

withRotation

Creates a rotation matrix from the given angle in radians.

Methods

invert

invert() -> Mat2D?

Provides indexed access to the matrix components. Returns the inverse of the matrix, or nil if the matrix is not invertible.

isIdentity

isIdentity() -> boolean

Returns true if the matrix is the identity transform.

__eq

__eq(rhs: Mat2D) -> boolean

Returns true if all components of the two matrices are equal.

__mul

__mul(rhs: Vector) -> Vector

Transforms the given vector by the matrix and returns the result.

__mul

__mul(rhs: Mat2D) -> Mat2D

Returns the matrix product of this matrix and the given matrix
