Introduction
Bevy is a refreshingly simple, data-driven game engine built in Rust. It is completely free and open-source, offering a robust foundation for both 2D and 3D game development. Bevy emphasizes a modular, data-oriented architecture using the Entity Component System (ECS) paradigm, aiming for high performance and developer productivity.
It's important to note that Bevy is still in early development, with new versions introducing breaking changes approximately every three months. Users should be prepared for an evolving environment, though migration guides are provided.
Installation
To get started with Bevy, you'll need a Rust development environment. The official Quick Start Guide provides comprehensive setup instructions.
Once your environment is ready, you can clone the Bevy repository and run one of its examples:
# Switch to the correct version (latest release, default is main development branch)
git checkout latest
# Runs the "breakout" example
cargo run --example breakout
For a minimal Bevy application, add bevy to your Cargo.toml and use the following code:
use bevy::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.run();
}
For faster iterative compiles, Bevy recommends a specific setup detailed in their Fast Compiles guide.
Examples
Bevy provides a rich set of official examples that are excellent for exploring specific concepts and features of the engine. These runnable examples serve as a practical learning resource for developers.
