Properties

gameObject

gameObject: GameObject

Reference to the GameObject this component is attached to This is a three.js Object3D with additional GameObject functionality

guid

guid: string = "invalid"

Unique identifier for this component instance, used for finding and tracking components

localhost

localhost: null | string = null

Alternative URL to use when running on a local network. This is particularly useful for development, when the server is running on the same machine as the client.

OptionalsourceId

sourceId?: string

Identifier for the source asset that created this component. For example, URL to the glTF file this component was loaded from

url

url: null | string = null

The websocket URL to connect to for networking functionality. Can be a complete URL or a relative path that will be resolved against the current origin.

urlParameterName

urlParameterName: null | string = null

Name of the URL parameter that can override the websocket connection URL. When set, the URL will be overridden by the parameter value from the browser URL. For example, with urlParameterName="ws", adding ?ws=ws://localhost:8080 to the browser URL will override the connection URL.
