Class Transform

java.lang.Object
com.codename1.gaming.physics.box2d.common.Transform
public class Transform extends Object
A transform contains translation and rotation. It is used to represent the position and orientation of rigid frames.

  • Field Details

    • p

      public final Vec2 p
      The translation caused by the transform

    • q

      public final Rot q
      A matrix representing a rotation

  • Constructor Details

    • Transform

      public Transform()
      The default constructor.

    • Transform

      public Transform(Transform xf)
      Initialize as a copy of another transform.

    • Transform

      public Transform(Vec2 _position, Rot _R)
      Initialize using a position vector and a rotation matrix.

  • Method Details

    • set

      public final Transform set(Transform xf)
      Set this to equal another transform.

    • set

      public final void set(Vec2 p, float angle)
      Set this based on the position and angle.
      Parameters:
      p -
      angle -

    • setIdentity

      public final void setIdentity()
      Set this to the identity transform.

    • toString

      public final String toString()
      Description copied from class: Object
      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())
      Overrides:
