Constructor Detail

• WakeupOnCollisionExit

  public WakeupOnCollisionExit(SceneGraphPath armingPath)

  Constructs a new WakeupOnCollisionExit criterion.

  Parameters:

  armingPath - the path used to arm collision detection

  Throws:

  IllegalArgumentException - if object associated with the SceneGraphPath is other than a Group, Shape3D, Morph, or BoundingLeaf node.

• WakeupOnCollisionExit

  public WakeupOnCollisionExit(SceneGraphPath armingPath,
                               int speedHint)

  Constructs a new WakeupOnCollisionExit criterion.

  Parameters:

  armingPath - the path used to arm collision detection

  speedHint - one of USE_GEOMETRY or USE_BOUNDS, specifies how accurately Java 3D will perform collision detection

  Throws:

  IllegalArgumentException - if hint is not one of USE_GEOMETRY or USE_BOUNDS.

  IllegalArgumentException - if object associated with the SceneGraphPath is other than a Group, Shape3D, Morph, or BoundingLeaf node.

• WakeupOnCollisionExit

  public WakeupOnCollisionExit(Node armingNode)

  Constructs a new WakeupOnCollisionExit criterion.

  Parameters:

  armingNode - the Group, Shape, or Morph node used to arm collision detection

  Throws:

  IllegalArgumentException - if object is under a SharedGroup node or object is other than a Group, Shape3D, Morph or BoundingLeaf node.

• WakeupOnCollisionExit

  public WakeupOnCollisionExit(Node armingNode,
                               int speedHint)

  Constructs a new WakeupOnCollisionExit criterion.

  Parameters:

  armingNode - the Group, Shape, or Morph node used to arm collision detection

  speedHint - one of USE_GEOMETRY or USE_BOUNDS, specifies how accurately Java 3D will perform collision detection

  Throws:

  IllegalArgumentException - if hint is not one of USE_GEOMETRY or USE_BOUNDS.

  IllegalArgumentException - if object is under a SharedGroup node or object is other than a Group, Shape3D, Morph or BoundingLeaf node.

• WakeupOnCollisionExit

  public WakeupOnCollisionExit(Bounds armingBounds)

  Constructs a new WakeupOnCollisionExit criterion.

  Parameters:

  armingBounds - the bounds object used to arm collision detection

Method Detail

• getArmingPath

  public SceneGraphPath getArmingPath()

  Returns the path used in specifying the collision condition.

  Returns:

  the SceneGraphPath object generated when arming this criterion---null implies that a bounds object armed this criteria

• getArmingBounds

  public Bounds getArmingBounds()

  Returns the bounds object used in specifying the collision condition.

  Returns:

  the Bounds object generated when arming this criterion---null implies that a SceneGraphPath armed this criteria

• getTriggeringPath

  public SceneGraphPath getTriggeringPath()

  Retrieves the path describing the object causing the collision.

  Returns:

  the SceneGraphPath that describes the triggering object.

  Throws:

  IllegalStateException - if not called from within the a behavior's processStimulus method which was awoken by a collision.

• getTriggeringBounds

  public Bounds getTriggeringBounds()

  Retrieves the Bounds object that caused the collision

  Returns:

  the colliding Bounds object.

  Throws:

  IllegalStateException - if not called from within the a behavior's processStimulus method which was awoken by a collision.
