Bevy is a refreshingly simple data-driven game engine built in Rust. It is free and open-source forever!
Bevy is still in the very early stages of development. APIs can and will change (now is the time to make suggestions!). Important features are missing. Documentation is sparse. Please don't build any serious projects in Bevy unless you are prepared to be broken by API changes constantly.
We recommend checking out The Bevy Book for a full tutorial.
# Switch to the correct version (latest release, default is main development branch) git checkout latest # Runs the "breakout" example cargo run --example breakout
Bevy can be built just fine using default configuration on stable Rust. However for really fast iterative compiles, you should enable the "fast compiles" setup by following the instructions here.
Bevy has the following Focus Areas. We are currently focusing our development efforts in these areas, and they will receive priority for Bevy developers' time. If you would like to contribute to Bevy, you are heavily encouraged to join in on these efforts:
Bevy is only possible because of the hard work put into these foundational technologies:
This list outlines the different cargo features supported by Bevy. These allow you to customize the Bevy feature set for your use-case.
Plugins are very welcome to extend Bevy's features. Guidelines are available to help integration and usage.
Additionally, we would like to thank the Amethyst, macroquad, coffee, ggez, rg3d, and Piston projects for providing solid examples of game engine development in Rust. If you are looking for a Rust game engine, it is worth considering all of your options. Each engine has different design goals, and some will likely resonate with you more than others.
Bevy is free and open source! All code in this repository is dual-licensed under either:
at your option. This means you can select the license you prefer! This dual-licensing approach is the de-facto standard in the Rust ecosystem and there are very good reasons to include both.
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
