Trouble Getting the Sitter's Key

I have been racking my brain and the wiki trying to figure out what is wrong with this code. It all looks great to me, but everytime I get a NULL_KEY from llAvatarOnSitTarget().
Does anybody see what my silly mistake is?


<CODE>

debug(string s){
llOwnerSay(s);
}



default{
state_entry(){
state Vacant;
}
}


state Vacant{
state_entry(){
debug("Vacant";
llSitTarget(<0,0,0>, llEuler2Rot(<0,PI/2,0>);
}

changed(integer c){
if(c & CHANGED_LINK){
key k = llAvatarOnSitTarget();
debug("K:|" + (string) k + "|";
}
}
}
</CODE>

You can use [ php] and [/php] to make code format nice on the forums..

Try giving a non-zero vector for the sit position. Doesn't have to be far from zero, just non-zero.

debug(string s){
    llOwnerSay(s);
}



default{
    state_entry(){
        state Vacant;
    }
}


state Vacant{
    state_entry(){
        debug("Vacant");
        llSitTarget(<0,0,0>, llEuler2Rot(<0,PI/2,0>));
    }
    
    changed(integer c){
        if(c & CHANGED_LINK){
            key k = llAvatarOnSitTarget();
            debug("K:|" + (string) k + "|");
        }
    }
}

Well, that fixed it. Can you tell me why that fixed it?

llSitTarget clears the target if the position vector is zero and llAvatarOnSitTarget will always return NULL_KEY if there's no sit target..

I knew it had to be something stupid. Thanks alot.
