.ListenerOptions: Interface

Registration options for a listener in an Emitter.

Properties

Name	Type	Description
id	any	Listener identifier. This is used to find and remove the listener without needing the callback reference. The identifier can be any type. However, remember that the comparison will be by-value for primitive types (string, number), but by reference for objects. For more information, please look at the remove method.
once	boolean	If `true`, the listener is automatically removed after it’s invoked. Defaults to `false`.

.LoadRuntimeOptions: Interface

Options to forward to loadRuntime

Properties

Name	Type	Description

physx	boolean	If `true`, forces the runtime to load a physx-compatible version. Note: If your scene uses physx, you must enable this option.
simd	boolean	If `true`, forces the runtime to load the SIMD-compatible version. If `undefined`, performs browser feature detection to check whether SIMD is supported or not.
threads	boolean	If `true`, forces the runtime to load the threads-compatible version. If `undefined`, performs browser feature detection to check whether threads are supported or not.
webgpu	boolean	If `true`, forces the runtime to load the webgpu-compatible version.

xrOfferSession	XROfferSessionOptions	1.1.5+ Whether to advertise AR/VR session support to the browser. Adds an interactive UI element to the browser interface to start an XR session. Browser support is optional, so it’s advised to still allow requesting a session with a UI element on the website itself. If `undefined`, no XR session is automatically offered to the browser.
