entry	scripting	gdscript	1	3	abstract-classes-and-methods	Abstract classes and methods	U Can’t Touch This	You can now declare GDScript classes to be abstract. Declaring a class abstract means that the class is not meant to be instantiated directly. That means that you can prevent instances of a class, let’s say, ``@[Animal](usertype)``, that doesn’t have any purpose on its own other than to be extended by "concrete" classes like ``@[Cat](usertype)`` and ``@[Dog](usertype)``. Abstract classes can also have abstract methods. This means that the method must be implemented in any class that extends it. <figure class="file"> <figcaption>animal.gd</figcaption> ```manual @[@abstract](gdscript-annotation) @[class_name](keyword) Animal @[extends](keyword) @[Node](enginetype) @[@abstract](gdscript-annotation) @[func](keyword) @[cry](function)@[() ->](symbol) @[void](basetype) ``` </figure> <figure class="file"> <figcaption>cat.gd</figcaption> ```manual @[class_name](keyword) Cat @[extends](keyword) @[Animal](usertype) @[func](keyword) @[cry](function)@[() ->](symbol) @[void](basetype) @[# Must be implemented, otherwise an error will be thrown.](comment) @[print](function)@[(](symbol)@["Meow!"](string)@[)](symbol) ``` </figure>	name github Aaron Franke aaronfranke name github Danil Alexeev dalexeev name github Ryan Brue ryanabx	https://github.com/godotengine/godot/pulls?q=is%3Apr+is%3Amerged+67777+106409+107717	Image of the Add Node window displaying the dimmed out abstract Animal node, and its two extending classes Cat and Dog.	/storage/releases/4.5/images/gdscript-abstract.webp	/storage/releases/4.5/images/gdscript-abstract-2x.webp	top	center-left
