A 3D game engine and visual editor built on Bevy 0.18.
Warning: Early alpha. Expect bugs, incomplete features, and breaking changes between versions.
AI-Assisted Development: This project uses AI code generation tools (Claude by Anthropic) throughout development. If that's a concern, check out Bevy, Godot, or Fyrox.
Prerequisites: Docker, and Rust just to install the CLI.
cargo install renzora # installs the `renzora` command
renzora new engine # scaffold a new project
cd engine
renzora run # build the editor and launch it (first run is slow)Everything builds inside a container, so Docker handles the rest — no toolchain or system libraries to set up, and the build is identical on every machine. The editor runs on your computer, not in the container.
| Command | What it does |
|---|---|
renzora new <name> |
Scaffold a new project. |
renzora run [editor|runtime] |
Build for your machine and launch it (editor by default). |
renzora build [platforms] |
Cross-build for one or more platforms (no args = all). |
renzora test |
Run the test suite. |
renzora add <name> [--editor|--dylib] |
Add a plugin crate. |
renzora remove <name> |
Delete a plugin crate. |
renzora shell |
Open a shell in the build container. |
Run renzora --help for the rest (init, check, upx, clean, destroy).
Platforms: windows, linux, macos, wasm, android, ios. Builds land in dist/<platform>/ — the runtime build doubles as a dedicated server (run it with --server).
