* bevy_pbr2: Add support for most of the StandardMaterial textures Normal maps are not included here as they require tangents in a vertex attribute. * bevy_pbr2: Ensure RenderCommandQueue is ready for PbrShaders init * texture_pipelined: Add a light to the scene so we can see stuff * WIP bevy_pbr2: back to front sorting hack * bevy_pbr2: Uniform control flow for texture sampling in pbr.frag From 'fintelia' on the Bevy Render Rework Round 2 discussion: "My understanding is that GPUs these days never use the "execute both branches and select the result" strategy. Rather, what they do is evaluate the branch condition on all threads of a warp, and jump over it if all of them evaluate to false. If even a single thread needs to execute the if statement body, however, then the remaining threads are paused until that is completed." * bevy_pbr2: Simplify texture and sampler names The StandardMaterial_ prefix is no longer needed * bevy_pbr2: Match default 'AmbientColor' of current bevy_pbr for now * bevy_pbr2: Convert from non-linear to linear sRGB for the color uniform * bevy_pbr2: Add pbr_pipelined example * Fix view vector in pbr frag to work in ortho * bevy_pbr2: Use a 90 degree y fov and light range projection for lights * bevy_pbr2: Add AmbientLight resource * bevy_pbr2: Convert PointLight color to linear sRGB for use in fragment shader * bevy_pbr2: pbr.frag: Rename PointLight.projection to view_projection The uniform contains the view_projection matrix so this was incorrect. * bevy_pbr2: PointLight is an OmniLight as it has a radius * bevy_pbr2: Factoring out duplicated code * bevy_pbr2: Implement RenderAsset for StandardMaterial * Remove unnecessary texture and sampler clones * fix comment formatting * remove redundant Buffer:from * Don't extract meshes when their material textures aren't ready * make missing textures in the queue step an error Co-authored-by: Aevyrie <aevyrie@gmail.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

What is Bevy?
Bevy is a refreshingly simple data-driven game engine built in Rust. It is free and open-source forever!
WARNING
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.
Design Goals
- Capable: Offer a complete 2D and 3D feature set
- Simple: Easy for newbies to pick up, but infinitely flexible for power users
- Data Focused: Data-oriented architecture using the Entity Component System paradigm
- Modular: Use only what you need. Replace what you don't like
- Fast: App logic should run quickly, and when possible, in parallel
- Productive: Changes should compile quickly ... waiting isn't fun
About
- Features: A quick overview of Bevy's features.
- Roadmap: The Bevy team's development plan.
- Introducing Bevy: A blog post covering some of Bevy's features
Docs
- The Bevy Book: Bevy's official documentation. The best place to start learning Bevy.
- Bevy Rust API Docs: Bevy's Rust API docs, which are automatically generated from the doc comments in this repo.
- Community-Made Learning Resources: Tutorials, documentation, and examples made by the Bevy community.
Community
Before contributing or participating in discussions with the community, you should familiarize yourself with our Code of Conduct and How to Contribute
- Discord: Bevy's official discord server.
- Reddit: Bevy's official subreddit.
- Stack Overflow: Questions tagged Bevy on Stack Overflow.
- Awesome Bevy: A collection of awesome Bevy projects.
Getting Started
We recommend checking out The Bevy Book for a full tutorial.
Follow the Setup guide to ensure your development environment is set up correctly. Once set up, you can quickly try out the examples by cloning this repo and running the following commands:
# Switch to the correct version (latest release, default is main development branch)
git checkout latest
# Runs the "breakout" example
cargo run --example breakout
Fast Compiles
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.
Focus Areas
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:
Editor-Ready UI
PBR / Clustered Forward Rendering
Scenes
Libraries Used
Bevy is only possible because of the hard work put into these foundational technologies:
- wgpu: modern / low-level / cross-platform graphics library inspired by Vulkan
- glam-rs: a simple and fast 3D math library for games and graphics
- winit: cross-platform window creation and management in Rust
- spirv-reflect: Reflection API in rust for SPIR-V shader byte code
Bevy Cargo Features
This list outlines the different cargo features supported by Bevy. These allow you to customize the Bevy feature set for your use-case.
Third Party Plugins
Plugins are very welcome to extend Bevy's features. Guidelines are available to help integration and usage.
Thanks and Alternatives
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.
