public class Transform

Object
Transform

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

Fields

`public final` `Vec2 p`	The translation caused by the transform
`public final` `Rot q`	A matrix representing a rotation

Constructors

`public Transform()`	The default constructor.
`public Transform(Transform xf)`	Initialize as a copy of another transform.
`public Transform(Vec2 _position, Rot _R)`	Initialize using a position vector and a rotation matrix.

Methods

`public final` `Transform set(Transform xf)`	Set this to equal another transform.
`public final void set(Vec2 p, float angle)`	Set this based on the position and angle.
`public final void setIdentity()`	Set this to the identity transform.
`public static final` `Vec2 mul(Transform T, Vec2 v)`
`public static final void mulToOut(Transform T, Vec2 v, Vec2 out)`
`public static final void mulToOutUnsafe(Transform T, Vec2 v, Vec2 out)`
`public static final` `Vec2 mulTrans(Transform T, Vec2 v)`
`public static final void mulTransToOut(Transform T, Vec2 v, Vec2 out)`
`public static final void mulTransToOutUnsafe(Transform T, Vec2 v, Vec2 out)`
`public static final` `Transform mul(Transform A, Transform B)`
`public static final void mulToOut(Transform A, Transform B, Transform out)`
`public static final void mulToOutUnsafe(Transform A, Transform B, Transform out)`
`public static final` `Transform mulTrans(Transform A, Transform B)`
`public static final void mulTransToOut(Transform A, Transform B, Transform out)`
`public static final void mulTransToOutUnsafe(Transform A, Transform B, Transform out)`
`public final` `String toString()`	Returns a string representation of the object.

toString

public final String toString()

Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
