Interface PositionChaser2D

All Superinterfaces:
X3DChaserNode, X3DChildNode, X3DFollowerNode, X3DNode
All Known Implementing Classes:
PositionChaser2D
public interface PositionChaser2D extends X3DChaserNode
PositionChaser2D generates a series of 2D position values that progressively change from initial value to destination value.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. PositionChaser2D node tooltip: (X3D version 3.2 or later) [X3DChaserNode] PositionChaser2D generates a series of 2D position values that progressively change from initial value to destination value.
  • Hint: ROUTE value_changed output events to a <TextureTransform> node's translation field, for example.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

  • Method Details

    • getDuration

      double getDuration()
      Provide double value in seconds within allowed range of [0,infinity) from initializeOnly SFTime field named duration.

      Tooltip: [0,+infinity) duration is the time interval for filter response in seconds.
      • Hint: duration is a nonnegative SFTime duration interval, not an absolute clock time.
      Specified by:
      getDuration in interface X3DChaserNode
      Returns:
      value of duration field

    • setDuration

      PositionChaser2D setDuration(double newValue)
      Accessor method to assign double value in seconds to initializeOnly SFTime field named duration.

      Tooltip: [0,+infinity) duration is the time interval for filter response in seconds.
      • Hint: duration is a nonnegative SFTime duration interval, not an absolute clock time.
      Specified by:
      setDuration in interface X3DChaserNode
      Parameters:
      newValue - is new value for the duration field.
      Returns:
      PositionChaser2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    • getInitialDestination

      float[] getInitialDestination()
      Provide array of 2-tuple float results from initializeOnly SFVec2f field named initialDestination.

      Tooltip: Initial destination value for this node. *
      Returns:
      value of initialDestination field

    • setInitialDestination

      PositionChaser2D setInitialDestination(float[] newValue)
      Accessor method to assign 2-tuple float array to initializeOnly SFVec2f field named initialDestination.

      Tooltip: Initial destination value for this node. *
      Parameters:
      newValue - is new value for the initialDestination field.
      Returns:
      PositionChaser2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    • getInitialValue

      float[] getInitialValue()
      Provide array of 2-tuple float results from initializeOnly SFVec2f field named initialValue.

      Tooltip: Initial starting value for this node. *
      Returns:
      value of initialValue field

    • setInitialValue

      PositionChaser2D setInitialValue(float[] newValue)
      Accessor method to assign 2-tuple float array to initializeOnly SFVec2f field named initialValue.

      Tooltip: Initial starting value for this node. *
      Parameters:
      newValue - is new value for the initialValue field.

      Tooltip: isActive true/false events are sent when follower-node computation starts/stops.
      • Warning: it is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
      Specified by:
      getIsActive in interface X3DChaserNode
