Scene.OnPeekTouchListener

  • Scene.OnPeekTouchListener is an interface used to receive callbacks for touch events on a Scene, prior to the Scene.OnTouchListener.

  • This listener is triggered for all motion events, even if consumed by another gesture, allowing observation of all touch interactions.

  • The onPeekTouch method provides details about the touch, including the HitTestResult (indicating the touched node, if any) and the MotionEvent.

  • ArFragment and BaseArFragment are indirect subclasses that implement or utilize this interface for AR interactions.

Interface definition for a callback to be invoked when a touch event is dispatched to a scene. The callback will be invoked before the Scene.OnTouchListener is invoked. This is invoked even if the gesture was consumed, making it possible to observe all motion events dispatched to the scene.
