    • incrementSoundSequence

      public boolean incrementSoundSequence()
      Removes the next filename from the sound sequence queue and assigns it to this source. This method has no effect on non-streaming sources. This method is used internally by SoundSystem, and it is unlikely that the user will ever need to use it.
      Overrides:

      Returns:
      True if there was something in the queue.

    • listenerMoved
