# System Requirements
- Screen, keyboard
2024-03-30 13:25:48 +00:00
- Operating System: Linux, Windows, MacOS
- Ideally, a graphics card with vulkan support

2024-03-30 13:25:48 +00:00
If your GPU does not support vulkan, try rendering with OpenGL by setting the environment variable `WGPU_BACKEND` to `gl`, like:
```
WGPU_BACKEND=gl ./outfly
or
WGPU_BACKEND=gl cargo run
```
However, this may result in poor performance and visual glitches.

# Running OutFly
1. Download a release for your operating system at https://codeberg.org/hut/outfly/releases
2. On Linux, you need the dependency packages: `glibc libcap gcc-libs alsa-lib systemd-libs`. These are the names for ArchLinux, they may differ on your distribution.
3. Unpack and run the outfly/outfly.exe executable.
1. On Windows, just double-click on outfly.exe
2. On Linux, open the console and type this:
```
cd [path-to-extracted-outfly-directory]
./outfly
```
# Building
2024-03-17 15:09:40 +00:00
If there is no package for the version or operating system that you need, or if you wish to tinker on the game, you can also build outfly yourself.
For development, it's recommended to use `--features dev` to enable dynamic linking for faster compile times, e.g. like this:
2024-03-17 15:09:40 +00:00
```
cargo [run|build] --features dev
2024-03-17 15:09:40 +00:00
```
## On Linux
Install the build dependencies. On ArchLinux, it's the following, though you can replace `rust` with `rustup`:
2024-03-17 15:09:40 +00:00
```
pacman -S rust libx11 pkgconf alsa-lib
```
Then run the following commands, replacing `[URL]` with the clone URL of the git repository:
```
git clone [URL]
cd outfly
cargo run --release
2024-03-17 15:09:40 +00:00
```
2024-03-18 01:24:52 +00:00
NOTE: Audio is muted by default when run through `cargo run`, unless you add `--release`
## Building for Windows on Linux
```
rustup target add x86_64-pc-windows-gnu
pacman -S mingw-w64-toolchain # on ArchLinux. other distros have their equivalent package
cargo build --target=x86_64-pc-windows-gnu --release
```

2024-03-30 12:52:15 +00:00
## Building on Mac OS
Install homebrew, and then get the following dependencies:
```
brew install pkg-config molten-vk rustup
rustup-init
```
Download, compile and run the game:
```
git clone [URL]
cd outfly
cargo run --release
```
