Node.OnTapListener

AI-generated Key Takeaways

• Node.OnTapListener is an interface used to handle tap interactions on Sceneform nodes.

• It provides a single method, onTap(), which is triggered when a node is tapped.

• onTap() receives a HitTestResult object containing information about the tap location and the tapped node, along with the corresponding MotionEvent.

• BaseTransformableNode and TransformableNode are known indirect subclasses that implement this interface, enabling tap interactions for transformable nodes in AR scenes.

public static interface Node.OnTapListener
