shortcircuited calls in a loop

Hi, I have a very strange problem
http://pastebin.com/m116979bf
This code works the only the FIRST time the av sits on the target.
On first sit the 3 debugs are shown :
1
2
3
1
Then the av 'stands up'
On 2. (and all consecutive 'sits') there is NO debug -eg the function 'changed' is NEVER called?!?
That not all..
The FIRST time an av sits on target the 'touch' function is ALSO not longer registrated??!
What on earth is going on?!
The function 'loop' is stopped (no debug from 'loop')

Not sure exactly what the problem is but doing something like this is probably not a good idea...

loop()
{
  while(bool==1)
  {
    rollCnt+=1;
    if(rollCnt==5000) //emote
    {
      agent = llAvatarOnSitTarget();
      if(agent)
      {
      llRequestPermissions(agent, PERMISSION_TRIGGER_ANIMATION);
      llStartAnimation("express_open_mouth");
      rollCnt=0; //reset cnt loop
      llSay(0, "reset");
      }
    }
  }
}

I've never tried to treat LSL like it's multi-threaded but expect that it won't be happy with the above code.

You'd be better off doing llSettimerEvent (5.0) when somebody starts sitting to set a 5-second timer then have something like

timer()
{
      agent = llAvatarOnSitTarget();
      if(agent)
      {
            if (llGetPermissions() & PERMISSION_TRIGGER_ANIMATION)
                  llStartAnimation("express_open_mouth");
      }
}

edit: also, you should call RequestPermissions when they sit but not actually stop/start the animations until you get a callback to run_time_permissions. From there, you can use GetPermissions to see if you were granted anim perms and do stop/startAnimation and set the timer if you got them.

I suggest removing the infinite loop in the loop() function (the 'bool' variable isn't changed within the while loop, so 'bool==1' is always true).

Hi, I used Meade's solution. It -is- properly not a good idea to try anything threaded in lsl..
Also this showed me hopw i can use timers
Thank You to both of you!

There is no such THING as a multi-threaded script. If you want multiple threads, you must use multiple scripts.

LSL is Monotonic, each event handler must complete before the next can execute.
