Help on "OnMove etc."

[Fpaciello1]

Hi I'm new to scene view / Ar Core, I added some 3D model using the listener onTapAr :

` onTapAr = { hitResult, _ ->
if (toolActive) {
val anchor = hitResult.createAnchor()
lifecycleScope.launch {
// Load a new model instance for each tap
val modelInstance = GLBLoader.loadModelInstance(
context = requireContext(),
glbFileLocation = "models/sphere.glb"
) as ModelInstance

                    val sphereModel = ArModelNode(sceneView.engine)
                    
                    sphereModel.scale = Scale(0.03f, 0.03f, 0.03f)
                    for (material in modelInstance.materialInstances) {
                        material.setBaseColor(Color(255f, 0f, 0f, 255f))
                    }
                    sphereModel.modelInstance = modelInstance
                    sphereModel.anchor = anchor
                    // Add the anchor node to the AR scene
                    sceneView.addChild(sphereModel)
                    }
           }`

Now I would like to add a listener to print some debug messages, like position of the sphereModel and rotation when I move it on the scene. I think I should use this :
public open fun onMove( detector: MoveGestureDetector, e: NodeMotionEvent ): Unit

But I can't find a way to work with it. Can you explain me how to use it or provide me some examples? I searched on the internet and I found nothing.
Thank you in advance!
