## What is Bevy?
|
|
|
|
Bevy is an open-source modular game engine built in Rust, with a focus on developer productivity and performance.
|
|
|
|
## WARNING
|
|
|
|
Bevy is still in the _very_ early stages of development. APIs can and will change. Important features are missing. Documentation is non-existent. Please don't build any serious projects in Bevy unless you are prepared to be broken by api changes constantly.
|
|
|
|
## Design Goals
|
|
|
|
* Provide a first class user-experience for both 2D and 3D games.
|
|
* Easy for newbies to pick up, but infinitely flexible for power users.
|
|
* Fast iterative compile times. Ideally less than 1 second for small to medium sized projects.
|
|
* Data-first game development using ECS (Entity Component System)
|
|
* High performance and parallel architecture
|
|
* Use the latest and greatest rendering technologies and techniques
|
|

|
## Getting Started
|
|
|
|
We recommend checking out [The Bevy Book](https://bevyengine.org/learn/book) for a full tutorial. You can quickly try out the [examples](/examples) by cloning this repo and running the following command:
|
|
|
|
```sh
|
|
# Runs the "scene" example
|
|
cargo run --example scene
|
|
```
|
|
|
|
### Nightly Compiler
|
|
|
|
Bevy requires nightly rust right now. It currently uses [specialization](https://github.com/rust-lang/rfcs/blob/master/text/1210-impl-specialization.md) features, which are unstable. If specialization goes stable soon then we can go back to a stable compiler. [There is actually good forward progress happening here](https://github.com/rust-lang/rust/pull/68970). In the meantime, we will try our best to remove specialization usage so we can go back to stable.

## Libraries Used
|
|
|
|
Bevy is only possible because of the hard work put into these foundational technologies:
|
|
|
|
* [wgpu-rs](https://github.com/gfx-rs/wgpu-rs): modern / low-level / cross platform graphics library inspired by Vulkan
|
|
* [legion](https://github.com/TomGillen/legion): a feature rich high performance ECS library
|
|
* [glam-rs](https://github.com/bitshifter/glam-rs): a simple and fast 3D math library for games and graphics
|
|
* [winit](https://github.com/rust-windowing/winit): cross platform window creation and management in Rust
|
|
* [legion_transform](https://github.com/AThilenius/legion_transform): A hierarchical space transform system, implemented using Legion ECS
|
|
* [shaderc](https://github.com/google/shaderc-rs): compiles GLSL and HLSL shaders to SPIR-V binaries
|
|
* [spirv-reflect](https://github.com/gwihlidal/spirv-reflect-rs): Reflection API in rust for SPIR-V shader byte code
|

Additionally, we would like to thank the [Amethyst](https://github.com/amethyst/amethyst), [coffee](https://github.com/hecrj/coffee), [ggez](https://github.com/ggez/ggez), and [Piston](https://github.com/PistonDevelopers/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. |
