llSensor not firing?

I am working on something that will take chat commands or touches,
and then record the position of the agent who touched it (think: easy
to config teleporter...)

Summary: why do I have to be so close to the object to fire off llSensor()?

So here is a bare bones example that I am stumped on. When I put this
in a prim and click on it, or chat at it, it works fine.. until I get about 10m
away! Is there some limit where I can't get llSensor to fire? I note that
when it does work, it picks up agents within the 96 m range just fine.

default
{
    state_entry()
    {
        llSay(0, "Hello, Avatar!");
        llListen(23, "", "", "");
    }

    touch_start(integer total_number)
    {       
        llSay(0, "Touched.");
        llSensor("", NULL_KEY, AGENT, 96, PI); 
    }


    listen(integer channel, string name, key id, string msg) {
        llSensor("", NULL_KEY, AGENT, 96, PI); 
     }


    sensor(integer total_number) {
        integer i;
        
        for (i = 0; i < total_number; i++) {
            llWhisper(0, "--> " + llDetectedName(i));
            
            vector curPos = llDetectedPos(i);
            integer x = llRound(curPos.x);
            
            llWhisper(0, " @ x" + (string)llRound(curPos.x) +
                " y: " + (string)llRound(curPos.y) +
                " z: " + (string)llRound(curPos.z));
        }        
    }
}

I notice that llWhisper has a range of ten meters. Maybe it's working but you just don't hear it when it's further away. llOwnerSay might be more useful for testing.

If it's not that... are you across a sim border when you are more than ten meters away? Sensors usually (but not always) tend to stop at the edge of the sim.

Cool, wasn't the sensor that was the problem at all

I got tripped up the fact that the prim couldn't reach me to report position.

Now I can move on to storing data, generating dialogs, and so on. thanks!
