Build from Source

Install Git and the Rust toolchain specified in Engine/rust-toolchain.toml.

Clone the repository and run:

git clone https://github.com/Rustic-Game-Engine/engine.git
cd engine/Engine

cargo install cargo-deny --locked --version 0.20.2
cargo xtask doctor
cargo xtask test
cargo xtask run project-manager

The project manager creates or imports projects and launches the editor.

Run Cargo commands from Engine/; the repository root is not a Cargo workspace. Check the engine README for platform requirements and troubleshooting.

Build the Windows Installer

From PowerShell on Windows, inside Engine/:

powershell -ExecutionPolicy Bypass -File .\tools\build-windows-installer.ps1

The installer is written to Engine/dist/.
