Transform class

A transform contains translation and rotation. It is used to represent the position and orientation of rigid frames.

Constructors

Transform.clone(Transform xf)

Initialize as a copy of another transform.

Transform.from(Vector2 position, Rot r)

Initialize using a position vector and a rotation matrix.

Transform.mul(Transform a, Transform b)

factory

Transform.mulTrans(Transform a, Transform b)

factory

Transform.zero()

The default constructor.

Properties

final

q → Rot

final

runtimeType → Type

A representation of the runtime type of the object.
