A 3D game engine and visual editor built on Bevy 0.19. It's fully compatible with the Bevy plugin ecosystem and is itself modular — every system is a plugin you can add, remove, or replace. Use it as a standalone engine to build games out of the box, or treat it as a customizable foundation you can modify into your own bespoke engine.
Warning: Early alpha. Expect bugs, incomplete features, and breaking changes between versions.
Prerequisites: Rust.
git clone https://github.com/renzora/engine.git
cd engine
cargo renzora # build, stage dist/, and launch the editorThat's the whole setup. cargo renzora builds the workspace natively, stages a complete engine into dist/<platform>/, and launches the editor from it. The first build is slow; every one after that is incremental.
On Linux you also need the usual graphics/audio dev headers:
sudo apt install pkg-config libx11-dev libxcursor-dev libxrandr-dev libxi-dev \
libwayland-dev libxkbcommon-dev libasound2-dev libudev-dev| Command | What it does |
|---|---|
cargo renzora |
Build, stage dist/<platform>/, and launch the editor. |
cargo renzora dist |
Build and stage without launching. |
cargo renzora profile |
Profiling build with Tracy instrumentation compiled in. |
cargo renzora sync |
Regenerate the plugin wiring from the renzora::add! declarations. |
cargo renzora remove <crate> |
Delete a plugin crate and every reference to it. |
Building the editor always builds the runtime too. The runtime doubles as a dedicated server — run it with --server.
Iterate with cargo check --profile dist and cargo clippy --profile dist; run tests with cargo test --profile dist -p <crate>. Always pass --profile dist — a bare cargo command builds a second full set of artefacts under target/debug/, and this workspace is far too large for two of them.
Shipping a game for a platform you're not sitting at — a macOS, Android, or web build from a Windows box — is part of the editor's export system, covered in the docs.
