DetectedKey using llAvatarOnLinkSitTarget is it possible?

[Cindy Kraai]

state_entry()
	{
		llListen(7, "", NULL_KEY, "");
		//with multiple listen channels here
	}
listen(integer chan, string name, key id, string msg)
    {
        if(chan = 7 && llDetectedKey(0) == llAvatarOnLinkSitTarget(3))
        {
			//listens only to the AvatarOnLinkSitTarget
		}
	}

i've been trying this but it doesn't seem to listen and im not sure if im doing it wrong. If there is an easy way please help, if none thanks anyway for viewing this post.

llDetected* functions don't work in listen() events, but you have the id variable to use instead.

Also, be careful with "=" (assignment) versus "==" (comparison). And personally I'd add a nest of parenthesis around each of the conditions being conjoined with &&, because I never remember operator precedence in different languages.

Another way of doing it is, when someone sits down, to open a listener listening only to that avatar.   Then remove the listener when the avatar stands up.    

If I can make the simulator do my filtering for me (which isn't always possible, of course) I will do.   So, something like this fragment: 

integer handle;
integer channel = 7;


default {
	
	changed(integer change){
		if(change & CHANGED_LINK){
			key k = llAvatarOnSitTarget();
			if(k){// if k is a valid key
				llListenRemove(handle);//close any old listeners
				handle = llListen(channel, "",k, "");//open a new listener, listening only to k
			}
			else{//k isn't a valid key, which means there's no one sitting on me, so whoever it was has just stood up
				llListenRemove(handle);//stop listening to whoever it was
			}
		}
	}
}
