Extensions

GDevelop is built in a flexible way. In addition to core features, new capabilities are provided by extensions. Extensions can contain objects, behaviors, actions, conditions, expressions or events.

Community created extensions are accessible directly from GDevelop. New extensions can also be created from scratch using events or JavaScript.

• Create your own extensions
