Methods

addEventListener

addEventListener<K extends keyof XRSessionEventMap>(
    type: K,
    listener: (this: XRSession, ev: XRSessionEventMap[K]) => any,
    options?: boolean | AddEventListenerOptions,
): void
Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.

end

end(): Promise<void>
Ends the WebXR session. Returns a promise which resolves when the session has been shut down.

- Optionaloptions: boolean | EventListenerOptions
Returns void
- Defined in .temp/typedoc/docdirectory/doc.d.ts:141417

requestAnimationFrame

requestAnimationFrame(callback: XRFrameRequestCallback): number
Schedules the specified method to be called the next time the user agent is working on rendering an animation frame for the WebXR device. Returns an integer value which can be used to identify the request for the purposes of canceling the callback using cancelAnimationFrame(). This method is comparable to the Window.requestAnimationFrame() method.
Parameters
- callback: XRFrameRequestCallback
Returns number
- Defined in .temp/typedoc/docdirectory/doc.d.ts:141389

requestLightProbe

requestLightProbe(options?: XRLightProbeInit): Promise<XRLightProbe>
The XRSession interface is extended with the ability to create new XRLightProbe instances. XRLightProbe instances have a session object, which is the XRSession that created this XRLightProbe.

Can reject with with a "NotSupportedError" DOMException
Parameters
- Optionaloptions: XRLightProbeInit
Returns Promise<XRLightProbe>
- Defined in .temp/typedoc/docdirectory/doc.d.ts:142077

requestReferenceSpace

requestReferenceSpace(
type: XRReferenceSpaceType,
): Promise<XRReferenceSpace | XRBoundedReferenceSpace>
Requests that a new XRReferenceSpace of the specified type be created. Returns a promise which resolves with the XRReferenceSpace or XRBoundedReferenceSpace which was requested, or throws a NotSupportedError if the requested space type isn't supported by the device.
Parameters
- type: XRReferenceSpaceType
Returns Promise<XRReferenceSpace | XRBoundedReferenceSpace>
- Defined in .temp/typedoc/docdirectory/doc.d.ts:141397
