Class JoalAudioListener

All Implemented Interfaces:
Comparable<NamedBean>, Audio, PropertyChangeProvider, AudioListener, NamedBean

JOAL implementation of the Audio Listener sub-class.

For now, no system-specific implementations are forseen - this will remain internal-only

      pos - new position
    • setVelocity

      public void setVelocity(javax.vecmath.Vector3f vel)
      Description copied from interface: AudioListener
      Sets the velocity of this AudioListener object

      Applies only to sub-types:

      • Listener
      • Source
      Specified by:
      setVelocity in interface AudioListener
      Overrides:
      setVelocity in class AbstractAudioListener
      Parameters:
      vel - 3d velocity vector

    • setGain

      public void setGain(float gain)
      Description copied from interface: AudioListener
      Set the gain of this AudioListener object

      Applicable values 0.0f to 1.0f

      When applied to Listeners, has the effect of altering the master gain (or volume)

      Applies only to sub-types:

      • Listener
      • Source
      Specified by:
      setGain in interface AudioListener

      public void setMetersPerUnit(float metersPerUnit)
      Description copied from interface: AudioListener
      Method to set the Meters per unit ratio for all distance calculations.

      Default value = 1.0f (i.e. 1 unit == 1 metre)

      Typical alternative values:

      • 0.3048f (i.e. 1 unit == 1 foot)
      • 0.9144f (i.e. 1 unit == 1 yard)

      Applies only to sub-types:

    • cleanup

      protected void cleanup()
      Description copied from class: AbstractAudio
      Abstract method that concrete classes will implement to perform necessary cleanup routines.

      This method is now included in dispose(). The caller can call dispose() to cleanup and deregister an audio object.

      Specified by:
      cleanup in class AbstractAudio
