XRInputSourceEvent

Constructor

XRInputSourceEvent()

Creates and returns a new XRInputSourceEvent object whose properties match those provided in the eventInitDict dictionary provided.

Instance properties

frame Read only

An XRFrame object providing the needed information about the event frame during which the event occurred. This frame may have been rendered in the past rather than being a current frame. Because this is an event frame, not an animation frame, you cannot call the XRFrame method getViewerPose() on it; instead, use getPose().

inputSource Read only

An XRInputSource object indicating which input source generated the input event.

Instance methods

The XRInputSourceEvent interface doesn't define any methods; however, several methods are inherited from the parent interface, Event.

Event types

select

Sent to an XRSession when the sending input source has fully completed a primary action.

selectend

Sent to an XRSession when an ongoing primary action ends, or when an input source with an ongoing primary action has been disconnected from the system.

selectstart

Sent to an XRSession when an input source begins its primary action, indicating that the user has begun a command-like input, such as pressing a trigger or button, issuing a spoken command, tapping on a touchpad, or the like.

squeeze

Sent to an XRSession when the sending input source has fully completed a primary squeeze action.

squeezeend

Sent to an XRSession when an ongoing primary squeeze action ends or when an input source with an ongoing primary squeeze action is disconnected.

squeezestart

Sent to an XRSession when an input source begins its primary squeeze action, indicating that the user has begun to grab, squeeze, or grip the controller.

Examples

The code below sets up handlers for primary action events in order to determine when the user clicks on (shoots at/pokes at/whatever) objects in the scene.

xrSession.addEventListener("select", (event) => {
  let targetRayPose = event.frame.getPose(
    event.inputSource.targetRaySpace,
    myRefSpace,
  );

  if (targetRayPose) {
    let hit = myHitTest(targetRayPose.transform);
    if (hit) {
      /* handle the hit */
    }
  }
});
