The core GUI object on which tools are built. Parent Frames/Labels/Buttons under this object to have them rendered as a 2D overlay. It must be placed in PlayerGui (or indirectly in StarterGui) in order to display. When inserted, the AbsolutePosition and AbsoluteSize will resemble that of the user's screen. This is a viable way to find the total size of your screen.

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

AbsolutePosition
Type	Vector2
Description	The distance, in pixels, from the top left corner of the game window.
Member of	GuiBase

AbsoluteSize
Type	Vector2
Description	Size of the render window in pixels.
Member of	GuiBase

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

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
