This is a work-in-progress branch of bevy to add openxr support. It is based mostly off of zarik5's work. The goal is to support both Oculus and PCVR.
If running on Oculus, download oculus sdk and move corresponding libraries into libs/
libs\arm64-v8a\libopenxr_loader.so
libs\armeabi-v7a\libopenxr_loader.so
Run the example with cargo run --example vr_cubes --release
This branch has 0.6 rebased in.
-
Get anything to render at all with vulkan
-
Use wgpu instead of Vulkan abstractions
- vk::ImageView -> wgpu::TextureView
- vk::Image -> wgpu::Texture
-
Integrate with bevy render pipeline
- currently using swapchain per-eye since bevy doesnt have multiview support yet
- bevy_openxr plugin replaces
RenderDevice
andRenderQueue
so that the render pipeline uses the device provided by openxr runtime - we also had to hack in adding an empty
Windows
so that plugins looking for windows such as bevy_ui and perspective camera don't panic - there are a few pipeline changes that had to be made that I will enumerate later (support for XrProjection camera projection, add hard-coded "left/right_eye" active cameras, support XrProjection frustra updates)
-
[] Add back in motion controller/input support (it was ripped out in an effort to get the example to not panic)
-
Prevent window from opening (shows as Not Responding on Windows OS).
-
Open Question: ability to have winit windows co-exist with openxr runner
- this could be useful for things like configuration UIs in pancake land
-
Get Oculus working
-
no winit needed
-
upgrading to ndk-glue 0.6.0 fixed the crash, but this will likely break normal android support until winit upgrades ndk-glue
-
-
MSAA
- Oculus claims to support 4x
-
bevy_ui
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.
MSRV: Bevy relies heavily on improvements in the Rust language and compiler. As a result, the Minimum Supported Rust Version (MSRV) is "the latest stable release" of Rust.
- 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
- Features: A quick overview of Bevy's features.
- News: A development blog that covers our progress, plans and shiny new features.
- 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.
- Official Examples: Bevy's dedicated, runnable examples, which are great for digging into specific concepts.
- Community-Made Learning Resources: More tutorials, documentation, and examples made by the Bevy community.
Before contributing or participating in discussions with the community, you should familiarize yourself with our Code of Conduct.
- Discord: Bevy's official discord server.
- Reddit: Bevy's official subreddit.
- GitHub Discussions: The best place for questions about Bevy, answered right here!
- Bevy Assets: A collection of awesome Bevy projects, tools, plugins and learning materials.
If you'd like to help build Bevy, check out the Contributor's Guide. For simple problems, feel free to open an issue or PR and tackle it yourself!
For more complex architecture decisions and experimental mad science, please open an RFC (Request For Comments) so we can brainstorm together effectively!
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
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 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
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, Fyrox, 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.
