Hmm, sorry, virtual buttons need unique names. You should be able to reuse a name after destroying a virtual button that previously had that name, however.

You could always append a counter to the name?

Works a treat! Thanks Kim.

My issue now comes with multiple enemies. If more than one enemy has the same name on the virtual button, only one of them can be destroyed and the others remain.

Is there a way around this need for unique VB names? Ideally I'd like to instantiate the same enemy multiple times.

In that sample the virtual button event handlers are attached to the image targets, so asking for the parent won't get you the soccer ball object. You can write a handler that is meant to be attached to the button object instead. Something like this:

using UnityEngine;
using System.Collections;

public class VBDestroy : MonoBehaviour, IVirtualButtonEventHandler
{
    void Start ()
    {
        VirtualButtonBehaviour vb = GetComponent<VirtualButtonBehaviour>();
        if (vb)
        {
            vb.RegisterEventHandler(this);
        }
    }

    public void OnButtonPressed(VirtualButtonBehaviour vb)
    {
        Debug.Log("OnButtonPressed");
        vb.GetImageTarget().DestroyVirtualButton(vb.VirtualButtonName);
        Destroy(this.transform.parent.gameObject);
    }

    public void OnButtonReleased(VirtualButtonBehaviour vb)
    {
        Debug.Log("OnButtonReleased");
    }
}

Note this destroys the virtual button as well, which might be a good idea if you don't intend to reuse it.
