rsaber: Beat Saber clone written in Rust

State

We are really at the beginning. At least, the colored notes are already moving :).

Supported Devices

Actually, any headset with OpenXR support + Vulkan API is supposed to work.

Download

You can go to releases to download pre-compiled binaries.

Build From Source

If you prefer, you can compile rsaber from sources. First of all, you need to have rust toolchain installed.

android

Prerequisite:

• Install Android Studio, then go to SDK Manager and install:

  • SDK Platforms -> Android 12L (API level 32)
  • SDK Tools -> NDK

• Setup rust toolchain, replace username and version as needed:

  rustup target add aarch64-linux-android
  cargo install cargo-apk
  set ANDROID_HOME=c:\Users\<username>\AppData\Local\Android\Sdk
  set ANDROID_NDK_ROOT=c:\Users\<username>\AppData\Local\Android\Sdk\ndk\<version>
  set PATH=%PATH%;c:\Program Files\Android\Android Studio\jbr\bin
  

In the past, manual downloading of OpenXR Loader was needed, but it has been integrated in the build process already.

Clone repo, connect Quest to PC, then build & run:

git clone https://github.com/bandipapa/rsaber.git
cd rsaber\android
cargo apk run

pc

Build & run:

cargo install rsaber_pc
rsaber_pc

You can use keys w-a-s-d to move, z-x to change elevation, r to reset view and arrow keys to rotate camera. Interaction with UI controls can be done with mouse.

pcvr

Prerequisite:

• cmake is needed to build OpenXR loader, go to https://cmake.org/, and install it.

Build & run:

cargo install rsaber_pcvr
rsaber_pcvr
