llMoveToTarget() not working.

Greetings,

I'm using the following code snippet to attempt to move an avatar. The code is in a HUD attachment:

CODE

state default
{
   // other code here ...

  sensor(integer total_number) 
  {
    pos = llDetectedPos(0);
    targetID = llTarget(pos, 0.5);
    llMoveToTarget(pos, 10);            
  }
	
  at_target(integer tnum, vector targetpos, vector ourpos)
  {
    llTargetRemove(targetID);
    llStopMoveToTarget();
  }
}


When executed the avatar doesn't move and consequently the at_target event never arrives (unless I manually move the avatar to the location, then the event fires). I've tried different tau values to no avail. Any idea what I'm doing wrong?

Thank you in advance!

Is the target within range? If it isn't, the script silently damps to the current position.

Also, according to comments on the wiki, llMoveToTarget() will fail to function in an attachment if the script has been compiled while the object is attached. Detaching and reattaching it is supposed to fix this problem.

I just tested this myself, and it's not working for me, either. I tried to make an attachment to jump on peoples' heads. :D

The at_target() event is not firing for some reason. Probably the best solution is to just forget the whole at_target() thing and run a timer that checks:

llVecMag( targetpos - llGetPos() ) < desired_target_distance, and call llStopMoveToTarget then.

You need to replace "state default" with "state", then it will work for you. :)
I just tried it, and it works fine with that change and adding a sensor event. Like:
CODE

integer Target;
default
{
    touch_start (integer Touches)
    {
        llSensor ("Avatar Name", NULL_KEY, AGENT, 96, PI);
    }
    sensor(integer total_number) 
    {
        vector Pos = llDetectedPos (0);
        Target = llTarget (Pos, 0.5);
        llMoveToTarget (Pos, 1.0);
    }
    attach (key Avatar)
    {
        if (NULL_KEY == Avatar)
        {
            llTargetRemove (Target);
            llStopMoveToTarget ();
        }
    }
    at_target(integer tnum, vector targetpos, vector ourpos)
    {
        llTargetRemove (Target);
        llStopMoveToTarget ();
    }
}
