Talk:Textbox2Hovertext

Listeners:

As your llListen() always has the same arguments (same channel and filtering by owner only) each llListen will be assigned to the same listener handle. So there's no danger of accumulating open listens, and your timer code could be simplified to:-

<lsl>

   timer()
   {
       llListenRemove(listenhandle);
       llSetTimerEvent(0.0);
   }

</lsl>

Unless your object gets handed on to multiple subsequent owners :)

If you want anyone to be able to set the hover text, then you could preclude multiple open listeners by removing the listen at the start of the touch event. It doesn't matter if it's already been removed by the timer code (or has never been assigned):-

<lsl>

  touch_start(integer num)
   {
       llListenRemove(listenhandle);
       key target = llDetectedKey(0);
       llSetTimerEvent(30.0);
       listenhandle = llListen(1, "", target, "");
       llTextBox( target, "Set Hovertext", 1 );
   }

</lsl>
