GDevelop JavaScript game engine reference

This is the documentation for the TypeScript/JavaScript game engine used in GDevelop.

GDevelop is an open-source, cross-platform game creator designed to be used by everyone. Download it at gdevelop.io to start making games.

Using JavaScript in your GDevelop game

When you're developing a game with GDevelop, the game is powered by this game engine and events of the game are using it.

If you want to use JavaScript in your game, insert a JavaScript event.

Then, you'll be interested in using these classes:

• gdjs.RuntimeScene for interacting with the scene.
• gdjs.RuntimeObject is the base class for object instances living on the scene.
• gdjs.RuntimeBehavior is the base class for behaviors attached to objects.
• gdjs.Variables are stored inside the game, scene and objects in gdjs.VariablesContainer.

Development of the TypeScript game engine (advanced)

If you want to work on the engine directly, follow the guide about development of the game engine to get started. Refer to this documentation to know more about the engine.
