GDevelop is a no-code game engine designed for building interactive 2D applications through a visual scripting environment. It allows users to define game logic and object interactions using a graphical interface of conditions and actions, eliminating the need for traditional programming. The platform functions as a cross-platform creator, enabling the export of projects to web, desktop, and mobile environments from a single codebase.
The engine is built on a modular game development extension framework that supports the creation and sharing of reusable behaviors and logic components. Developers can package custom actions, conditions, and expressions into isolated modules, which can then be distributed within the community to accelerate the development process. This architecture relies on component-based object composition, allowing for the creation of autonomous, reusable units that maintain encapsulated state and logic across different scenes.
The system utilizes an event-sheet-based execution model that translates visual logic into platform-specific code during compilation. By employing behavior-driven logic injection and data-driven scene serialization, the engine ensures consistent performance and structure across various deployment targets. Users can further extend project functionality by defining custom behaviors that automate movement, animation, and state changes for game entities.
