/**

* Welcome to the PlayCanvas Engine API Reference. The PlayCanvas Engine is an open source framework

* for building interactive 3D applications. It is written in JavaScript and is built on top of

* standard browser APIs including WebGL, WebGPU, Web Audio and WebXR.

*

* ### 🧑 Who Should Use This Manual?

*

* This API reference is intended for developers who are building applications using:

*

* - The [PlayCanvas Engine](https://github.com/playcanvas/engine) directly.

* - [PlayCanvas Web Components](https://github.com/playcanvas/web-components) or

* [PlayCanvas React](https://github.com/playcanvas/react) which wrap the PlayCanvas Engine

* with a declarative interface.

* - The [PlayCanvas Editor](https://playcanvas.com/products/editor) which supports the writing of

* custom scripts based on the Engine API.

*

* ### 🔍 Searching the API Reference

*

* You can search the API Reference by clicking the 🔍 icon in the header. The `/` key is a shortcut

* for opening the search dialog. Press `Escape` to close the search dialog.

*

* ### 🗺️ Navigating the API Reference

*

* This top level page groups the API into a number of categories: Animation, Asset, Debug, Exporter,

* Gizmo, Graphics, Input, Math, Other, Physics, Script, Sound, User Interface and XR.

*

* There is also a full alphabetical index available on the left hand side of the page. However,

* this list is extensive so here is a list of key classes that you can use as jumping on points

* for exploring the API:

*

* - {@link AppBase} - Represents your PlayCanvas application.

* - {@link Scene} - Represents the graphical scene managed by the application.

* - {@link Entity} - Represents objects in your app. The scene manages a hierarchy

* of entities. Add capabilities to entities with {@link Component}s.

* - {@link ScriptComponent} - A powerful component that allows you to write {@link Script}s

* that implement custom behavior for your entities.

* - {@link AssetRegistry} - Manages all the {@link Asset}s (3D models, sounds, etc) in your app.

*

* ### 🙌 Contributing to the API Reference

*

* We want the API Reference to be as high quality as possible. If you spot any errors or omissions,

* please raise an issue or open a pull request on the [PlayCanvas Engine GitHub repository](https://github.com/playcanvas/engine).
