Function: llSetSoundQueueing( integer queue );

Set whether attached sounds wait for the current sound to finish. If queue is TRUE, queuing is enabled, if FALSE queuing is disabled. Sound queuing is disabled by default.

• integer queue boolean, sound queuing: TRUE enables, FALSE (default) disables


  • It appears that only two sounds can be queued per prim. SVC-4260
  • Sound queuing is a property of the prim, not the script. It can be activated and deactivated by any script in the prim and survives script reset, rerez and script removal.
  • If used to make smooth transitions using slave/master sounds the sounds tend to go out of sync.
  • There is a very small (but audible) gap of silence between sounds due to network latency and processing time.
  • The queued sound must be fully loaded in the viewer, or else it will not play. llPreloadSound is not always reliable in doing its job.
  • Queueing a sound that is identical to the one currently playing will fail. Use llLoopSound instead.

        llPreloadSound("SoundName1");//This loads the sounds into all in range viewers and cuts delay between sounds.
        llPreloadSound("SoundName2");//All sound parameters can be the name of a sound in the prim's inventory or a UUID of a sound");
    touch_start(integer detected)
        llSetSoundQueueing(TRUE);//Set to TRUE for queueing and SoundName2 plays after the SoundName1 has ended.
        //Set to FALSE only the second will be played since the prim has only one sound emmiter and the second was called last.
        //Can be set anywhere withing the script (if within an event it will activate when the event is triggered.
        llPlaySound("SoundName1", 1.0);
        llPlaySound("SoundName2", 1.0);

   Since llSetSoundQueueing only allows two sounds to be played in queue can it be changed to allow more?
