Virtual Buttons

Hello Community,

im desperate and thats why im posting here. I followed several tutorials but i didn't get any solution and thats why im here now

I use the Vuforia Framework and Im trying to implement a virtual button to rotate my 3D Model.

After putting the Virtual Button, which is a child of my image target, above the image target, i don't get "button pressed" in the console, when i "hit" the button

in play mode. I renamed the virtual button to RotateZombieButton. 

Is this enough information or do i need to provide more information?

thanks in advance!

using System.Collections;using System.Collections.Generic;using UnityEngine;using Vuforia;public class VBScript : MonoBehaviour, IVirtualButtonEventHandler {private GameObject VBButtonObject;void Start () {  VBButtonObject = GameObject.Find ("RotateZombieButton");  VBButtonObject.GetComponent<VirtualButtonAbstractBehaviour> ().RegisterEventHandler (this);}// Update is called once per framepublic void OnButtonPressed (VirtualButtonAbstractBehaviour vb) {  Debug.Log ("Button pressed");}public void OnButtonReleased (VirtualButtonAbstractBehaviour vb) {  Debug.Log ("Button released");}}
