Finding objects in the area.

Is there an easy way to get the keys of all objects within a specific range of another object? I've noticed some scripts that detect people in the area and I'm guessing it's something like this. I've looked at llSensor and llSensorRepeat but they both require you to know the name and key of the object. :-/

No they don't

llSensor("", NULL_KEY, ACTIVE | PASSIVE | SCRIPTED, 25, PI);

Gets the 16 closest objects in a 25 meter radius from the middle of the sensing object.

Thanks Jillian,

I missed the part about using null string / NULL_KEY. Thanks for the pointer
