//! game-test: gameplay shared between `cargo run` and the
//! editor's Play button.
//!
//! Scene content (entities, components, positions) lives in
//! `assets/*.bsn` files authored in the editor. Game behaviour
//! (systems, observers, resources) lives in [`GamePlugin`].
//!
//! # Try it
//!
//! 1. Open this project in jackdaw.
//! 2. Hierarchy: right-click, `Add > Cube`.
//! 3. Inspector: `Add Component > SpinningCube`. Set `speed` to `1.5`.
//! 4. `File > Save`, then click Play. The cube spins.
//! 5. `cargo run` launches the same game without the editor.
//!
//! # Adding your own components
//!
//! Write a component anywhere in this library (any module, not
//! `main.rs`), deriving `Component, Reflect, Default` with
//! `#[reflect(Component, Default)]`, like `SpinningCube` below. After you
//! save, click Rebuild in jackdaw (or run `jd build`) and it
//! appears in `Add Component`. No registration code is needed.
