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.
