TranslationController

  • The TranslationController class manages the movement of a BaseTransformableNode within an AR scene using drag gestures.

  • It selects the BaseTransformableNode when a drag gesture begins if it's not already selected and then manipulates its position.

  • Developers can control the allowed plane types for translation using getAllowedPlaneTypes and setAllowedPlaneTypes methods.

  • It provides methods like canStartTransformation, onContinueTransformation, and onEndTransformation to manage the transformation lifecycle.

  • isTransforming indicates the current transformation state of the controlled node.
public class TranslationController

Manipulates the position of a BaseTransformableNode using a DragGestureRecognizer. If not selected, the BaseTransformableNode will become selected when the DragGesture starts.
