|
|
// A part of a controller set for NPC's
|
||
|
|
// When an avatar (the owner is not counted) gets close to this, it sends a @go command to the controller. This will make it continue from an @stop.
|
||
|
|
// when no one is around, it sends a @stop to remove the NPC. It sends these once per avatar presence.
|
||
|
|
// Does not use a laggy sensor. Will not detect the owner.
