Warning: The book and tools repository are severely out of date at the moment. Amethyst is undergoing a lot of changes at the moment so if you are looking to use the library it would be better to just read the examples.
This project is a work in progress and is very incomplete; pardon the dust! Read a summary of what happened this past week at This Week in Amethyst.
Amethyst is a fast, data-oriented, and data-driven game engine suitable for rapid prototyping and iteration. It also tries to push the Rust programming language to its limits, driving further improvement and hopefully attracting more game developers toward the young and vibrant Rust ecosystem.
The engine's design draws much inspiration from the industrial-strength Bitsquid Engine (now called Autodesk Stingray). However, Amethyst does not aim to be API-compatible with it in any way. Some goals include:
- Simple game state management in the form of a pushdown automaton.
- Massively parallel architecture, especially in rendering.
- Correct entity-component-system model, with entities and prefabs largely defined in Ron files.
- Abstract scripting API that can be bound to a variety of embedded languages, such as mruby, Lua, etc.
- Renderer optimized for modern graphics APIs, e.g. Vulkan, Direct3D 12+, Metal.
- Easy integration with useful third-party game development libraries, e.g. Piston.
- Traditional "mega-editor" split into several small but well-integrated tools, adhering to the Unix philosophy.
Linux developers: the libasound2-dev package will be required to compile Amethyst.
Read the online book for a comprehensive tutorial to using Amethyst. There is also an online crate-level API reference.
See the Getting Started chapter in the book for the full-blown "Hello,
World!" tutorial. For the sake of brevity, you can generate an empty game
project with cargo and build it. Follow along below:
You can build the book locally with:
$ cargo install mdbook
$ mdbook build book
The text can be found in book/html/index.html. To generate the API
documentation locally, do:
$ cargo doc
The API reference can be found in target/doc/amethyst/index.html.
We do not support anything other than the most recent Rust stable release. Use nightly and beta channels with this project at your own risk.
