Crate bevy

Bevy is an open-source modular game engine built in Rust, with a focus on developer productivity and performance.

Check out the Bevy website for more information, read the Bevy Book for a step-by-step guide, and engage with our community if you have any questions or ideas!

Example

Here is a simple “Hello World” Bevy app:

use bevy::prelude::*;

fn main() {
   App::build()
       .add_system(hello_world_system.system())
       .run();
}

fn hello_world_system() {
   println!("hello world");
}

Don’t let the simplicity of the example above fool you. Bevy is a fully featured game engine and it gets more powerful every day!

This Crate

The bevy crate is just a container crate that makes it easier to consume Bevy subcrates. The defaults provide a “full” engine experience, but you can easily enable / disable features in your project’s Cargo.toml to meet your specific needs. See Bevy’s Cargo.toml for a full list of features available.

If you prefer, you can also consume the individual bevy crates directly. Each module in the root of this crate, except for the prelude, can be found on crates.io with bevy_ appended to the front, e.g. app -> bevy_app.
