"Instance" redirects here. For the table, see Instance (Table).
Uncreatable:This object cannot be created with the Instance.new function.
Base class for all objects in game hierarchy. You cannot directly create Instances, instead you use these on any game object.
Clone( )
Returns Instance
Description: Returns a clone of the object and its children, unless its Archivable property is false. The clone will have the same properties as the original object and the same descendants (except those with an Archivable property set to false). The clone's Parent will be nil.
Member of: Instance
FindFirstChild( string name, bool recursive = false )
Returns Instance
Description: Returns the first child found with a name of name. Returns nil if no such child exists. If the optional recursive argument is true, will recursively descend the hierarchy while searching rather than only searching the immediate object.
Member of: Instance
GetChildren( )
Returns table
Description: Returns a read-only table of the object's children.
Member of: Instance
GetDebugId( int scopeLength )
Returns string
Description: Returns a coded string of the object's DebugId used internally by Roblox.
Member of: Instance
GetFullName( )
Returns String path to object
Description: Returns a string with a dot (.) character separating a path of object hierarchy excluding "game".
Member of: Instance
IsA( string className )
Returns bool
Description: Returns true if the Instance is that class or a subclass.
Member of: Instance
IsAncestorOf( Instance descendant )
Returns boolean is ancestor
Description: Returns true if the object is an ancestor of descendant.
Member of: Instance
IsDescendantOf( Instance ancestor )
Returns bool
Description: Returns true if the object is an descendant of ancestor.
Member of: Instance
Destroy( )
Returns nil
Description: Sets the Parent property to nil, locks the Parent property, disconnects all connections and calls Destroy() on all children.
Member of: Instance
ClearAllChildren( )
Returns nil
Description: Removes all descendants of the Instance, but leaves the Instance itself.
Member of: Instance
Name
Type string
Description The name of the object, which is often used to identify it in the context of its parent. Note that names are not unique identifiers; multiple children of an object may share the same name. In a script where you want to access an object using a name, for example, game.Workspace["Brick"], the first object found with that name is that object. This "first object" can be found in the Explorer menu.Names are great for showing a very brief title or summary of an object.
Member of Instance
Parent
Type Instance
Description The hierarchical parent of the object. When no scripts hold references to an object, it will still be maintained as long as it's parent is set to an object which does have references to it, either by other objects or scripts. The toplevel DataModel object (the one referred to as the "game" by scripts) has no parent, but always has a reference held to it by the game engine, and exists for the duration of a session.
Member of Instance
Archivable
Type bool
Description Sets whether or not the object is saved when publishing or saving to file. Also sets whether or not the object is clonable.
Member of Instance
ClassName
Type string
Description A unique string per type of Instance. Should only be used as a unique identifier, as it does not reveal any information about nature of the type hierarchy the type is in. For this use, see IsA.
Member of Instance
RobloxLocked
Type bool
Description If true, the object and its descendants cannot be indexed or edited by a Script or LocalScript and will throw an error if it is attempted.
Member of Instance
DataCost
Type int
Description How much saving this instance with SaveInstance will add to DataComplexity
