Mat2D

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

Fields

xx

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

Creates a matrix using the specified components.

identity

Returns the identity matrix.

withRotation

Creates a rotation matrix from the given angle in radians.

Methods

invert

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

isIdentity

Returns true if the matrix is the identity transform.

__eq

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

__mul

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

__mul

Returns the matrix product of this matrix and the given matrix
