Ecspanse is an Entity Component System (ECS) framework for Elixir.
Ecspanse is not a game engine, but a flexible foundation for managing state and building logic offering features like:
- flexible queries with multiple filters
- dynamic bidirectional relationships
- versatile tagging capabilities
- system event subscriptions
- asynchronous system execution
The full documentation for the Ecspanse project is available on HexDocs.
Ecspanse draws inspiration from the API of bevy_ecs. However, while Bevy is a comprehensive game engine, Ecspanse focuses on providing an Entity Component System (ECS) library in Elixir. The concepts described in the unofficial cheatbook also served as valuable references during development.
Please note that Ecspanse does not claim to be a Bevy equivalent in Elixir. If you're seeking a fully-featured ECS game library, please give Bevy a try.
Refer to the Getting Started guide for installation instructions.
The step-by-step Tutorial guides you through building a simple game, introducing key features of the framework along the way.
This is the code used in the Ecspanse Tutorial. You can find it on GitHub.
This multiplayer game was built with Ecspanse during the library's development. Check out its GitHub repository. The game is currently hosted on fly.io and can be played HERE.
