handleAvatarZoneChange()

handleAvatarZoneChange	(		self,

handleChildArrive()

handleChildArrive	(		self,

A new child has just setLocation beneath us.  Give us a
chance to run code when a new child sets location to us. For
example, we may want to scene graph reparent the child to
some subnode we own.

Reimplemented from DistributedObjectBase.

handleChildArriveZone()

handleChildArriveZone	(		self,
			childObj,
			zoneId )

A child has just changed zones beneath us with setLocation.
Give us a chance to run code when an existing child sets
location to us. For example, we may want to scene graph
reparent the child to some subnode we own.

Reimplemented from DistributedObjectBase.

handleChildLeave()

handleChildLeave	(		self,
			childObj,
			zoneId )

A child is about to setLocation away from us.  Give us a
chance to run code just before a child sets location away from us.
