AncestryChanged (Event)

AncestryChanged ( Instance child, Instance parent )
Description	Fired when an ancestor of the Instance the event which is a member of child has its parent changed to parent.
Member of:	Instance

Example

local p = Instance.new("Part")
p.Parent = game.Workspace
p.AncestryChanged:connect(function(child, parent)
  print(child.Name.." is now a child of "..parent.Name)
end)
p.Parent = game.Lighting --fires event

Notes

• child can be the object the event is a member of, or any of its ancestors. For example, if a Part is a child of a Model and the Model's parent is changed to Lighting, AncestryChanged would be fired on the Part with child being the Model and parent being Lighting.
• parent can be nil. This event can be used to see when an Instance is removed from the game by testing if parent is nil.
