rsaber: Beat Saber clone written in Rust

State

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

Supported Devices

Subdirectory	Tested devices
android	Meta Quest 2
pc	Windows (runs in a window, useful for debugging)
pcvr	OpenXR (SteamVR): Sony PlayStation VR2 (see https://www.playstation.com/en-us/support/hardware/pc-prepare-ps-vr2/)

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

First of all:

You need to have rust toolchain installed.

Clone this repo:

git clone https://github.com/bandipapa/rsaber.git

The built-in demo song can be replaced by downloading songs from https://beatsaver.com/, and overwrite asset/song/demo.

android

Prerequisite:

Install Android Studio, then go to SDK Manager and install:
- SDK Platforms -> Android 12L (API level 32)
- SDK Tools -> NDK
OpenXR Loader
- Go to https://mvnrepository.com/artifact/org.khronos.openxr/openxr_loader_for_android
- Download latest aar (which is actually a zip file), and extract jni/arm64-v8a/libopenxr_loader.so into android/lib/arm64-v8a/libopenxr_loader.so

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

Connect Quest to PC, then build:

cd android
cargo apk run

pc

Build:

cd pc
cargo run

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.

pcvr

Prerequisite:

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

Build:

cd pcvr
cargo run

TODO

Saber<->note collision detection
UI/menu system
Linux port
Put all assets into binary, but have the option to dump/read it from local file (this is for modders who don't want to recompile)
Package crates properly, so they can be used with "cargo install"
