This causes the scene tree to be non-functional for any sample that relies on properties or signals configured in the editor. If the latter isn't present, the editor will skip properties or signals associated with the missing native scripts in the scene. A simple "Hello world" application could look like this: use gdnative::prelude::* īefore launching the examples in the Godot editor, you must first run cargo build and wait for the build operations to finish successfully.Īt startup, the Godot editor tries to load all resources used by the project, including the native library. The necessary wiring is done behind the scenes by godot-rust. This happens via dynamic libraries and the GDNative interface, which will be loaded from Godot. ![]() The resulting native script can be attached to the scene tree, just like GDScript (. ExampleĪ typical use case is to expose your own Native Class, a Rust API that can be invoked from the Godot engine. See this page in the book for an introduction to use the async feature with Tokio. Async/yield supportĪsync support is a work-in-progress, with a low-level API available in gdnative::tasks, if the async feature is enabled on gdnative. To use the bindings with a different Godot version or a custom build of the engine, see Custom Godot builds in the user guide. We also do not guarantee any SemVer compatibility here. We have a relatively sophisticated CI and test suite for basic stability, but the GitHub version is typically more experimental and less battle-tested than a crates.io release. If you would like to benefit from cutting-edge features and bugfixes, you can use the GitHub version. After bindgen dependencies and a current Godot version are installed, add the gdnative crate as a dependency, and set the crate type to cdylib: This is the recommended way of using godot-rust. In case of problems, consider also reading the FAQ. Getting startedĭetailed setup is explained in the Getting Started section of the book. Support is planned as the native extensions become more stable. The bindings do not support in-development Godot 4 versions at the moment. We are committed to keeping compatibility with the latest stable patch releases of all minor versions of the engine, starting from Godot 3.2:įor versions 3.2 and 3.3, some extra steps are needed, see Custom builds below. Minimum supported Rust version (MSRV) is 1.56. ![]() godot-rust adheres to Cargo's semantic versioning. The bindings cover most of the exposed API of Godot 3.4, and are being used on a number of projects in development, but we still expect non-trivial breaking changes in the API in the coming releases. This allows you to develop games or other applications in Godot, while benefiting from Rust's strengths, such as its type system, scalability and performance. Godot-rust is a Rust library that implements native bindings for the Godot game engine.
