Sensing a specific object worn by an avatar

Hi!

I am trying to sense a specific object worn by an avatar, but the script fails to report the object when the object is actually worn by an avatar. If I place the object infront of the sensor without being attached to an avatar, the sensor sees it ok. When worn, the sensor does not see it at all. I am really struggling with this and any help would be very much appreciated.

default
{
    state_entry()
    {
        llSensorRepeat("", NULL_KEY, AGENT | ACTIVE | PASSIVE | SCRIPTED, 2.0, PI/2, 1);
        llOwnerSay("Sensor initialised...");
    }
        sensor(integer num_detected)
    {
        integer i;
        for(i = 0; i < num_detected; i++)
        {
            if ((string)llDetectedName(i) == "specific object")
        {
            llOwnerSay("specific object detected with scan range");
        }
    }
}
}

Right, it won't work with a sensor. See , to wit:One can, however, script an attachment to respond to a query, so instead of trying to sense it, one can just ask it whether it's there, just using a pair of llListen()s and llSays()s on obscure channels.

Ahh, I get it now.

Thanks for your help Qie. I need an object to communicate with an attached object. Basically, the avatar has a worn attachment, the avatar walks within range of the sensor and the sensor script does 'something' when the avatar is wearing the correct attachment, so if I use the fixed object to sense any avatar within range, then llSay(message), if the avatar is wearing the specific object and the message is correct, then the attached object can return llSay(message) back to the fixed object, and then the fixed object can run its course.

Please correct me if I am wrong with this, but i think this is right.

Correct although you may want to check that the responce comes from the attachment of the avatar you detected rather than another who may just be within listen/chat distance.

Thanks Newgate. I've managed to sort the script now. It works like this:

Avatar walks in sensor range
sensor script says a message on an obscure channel
object worn on avatar filters the specific message on the obscure channel and says a response on another obscure channel
sensor script filters message and if the resonse is right does its job

Thanks for you help, both of you
