If a class inherits from Object, you will have to delete instances of it manually. To do so, call the [method free] method from your script or delete the instance from C++. Some classes that extend Object add memory management. This is the case of [Reference], which counts references and deletes itself automatically when no longer referenced. [Node], another fundamental type, deletes all its children when freed from memory. Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in [method _get_property_list] and handled in [method _get] and [method _set]. However, scripting languages and C++ have simpler means to export them. + Property membership can be tested directly in GDScript using [code]in[/code]: + [codeblock] + var n = Node2D.new() + print("position" in n) # Prints "True". + print("other_property" in n) # Prints "False". + [/codeblock] Objects also receive notifications.
