# Shrooms VB (native)
|
||||
|
||||
An SDL-based implementation of shrooms-vb.
|
||||
A native implementation of shrooms-vb. Written in Rust, using winit, wgpu, and Dear ImGui. Should run on any major OS.
|
||||
|
||||
## Setup
|
||||
|
||||
Install the following dependencies:
|
||||
- `gcc` (or MinGW on Windows) (or whatever, just set `CC`)
|
||||
- `pkg-config`
|
||||
- sdl2
|
||||
- `cargo`
|
||||
|
||||
Run
|
||||
```sh
|
||||
make build
|
||||
cargo build --release
|
||||
```
|
||||
|
||||
The executable will be in `target/release/shrooms-vb[.exe]`
