this should be easy

hey, im using sensors to detect people in my room, and that works fine, but inestead of using notecard to select people allowed, is their a way to either get the persons current group status (make them be in my gourp when in room) or see if their a liseted member of my gourp instead of haveing to edit the notecard all the time?

Try llSameGroup(key k). It requires that the people already be wearing the groups tag though.
