Virtual button trigger animation

Hello all,


I have a question about virtual buttons. I want to start an animation on my cube object.

Now I have this script:

using UnityEngine;

using System.Collections;


public class VirtualButtonHandler : MonoBehaviour, IVirtualButtonEventHandler{


    private GameObject cube;


// Use this for initialization

void Start () {

// Register with the virtual buttons TrackableBehaviour

        VirtualButtonBehaviour[] vbs = GetComponentsInChildren<VirtualButtonBehaviour>();

        for (int i = 0; i < vbs.Length; ++i)





        // Get handle to the teapot object

        cube = GameObject.Find("cube").gameObject;




    // Called when the virtual button has just been pressed:

    public void OnButtonPressed(VirtualButtonBehaviour vb)




        // Add the material corresponding to this virtual button

        // to the active material list:

        switch (vb.VirtualButtonName)


            case "green":


cube.animation.wrapMode = WrapMode.Once;






    // Called when the virtual button has just been released:

    public void OnButtonReleased(VirtualButtonBehaviour vb)



        // Remove the material corresponding to this virtual button

        // from the active material list:

        switch (vb.VirtualButtonName)


            case "green":







And dragged it onto the virtual button.

When I test the app the cube is displayed but the animation is not triggered when I push the virtual button.

Did I forget something or is the script not correct?


Thanks in advise.

Yes confirm that the name is defined and also that your VB event handler is attached to the parent ImageTarget  - not the VB itself.

You'll also want to check within the event handler to confirm that the names correspond.


the button is called green everywere and my structure is: 

-AR camera

-directional light

-imagetarget (virtualbuttoneventhandler)



it seems to be that the script is not correctly loading:

Had you once used a version of this script that did not derive from MonoBehaviour, or another script on ImageTargets that did not derive from MonoBehaviour?

That error is associated w/ a known Unity bug.

I dont know what are you talking about the mono behiavour.... i compiled 4 or 5 proyects using just animations but never with VB. 

the proyect runs but the button doesnt do anything, reimported everything but still the same notice... here are some specs:


If you look at the image below you see that I named the button in the inspector pane on two places at the top and at Virtual Button Behaviour (Script). That's important to get the button to work.
