Vuforia添加虚拟按键

AR虚拟按键为真实识别图上的按键，通过按键可以实现真实与虚拟之间的按键交流。

（一）添加按键

点击target，打开advance，添加虚拟按键，即可在此target下添加虚拟按键

注：虚拟按键无法旋转，只能更改长宽，可以通过Name给虚拟按键添加一个标识，通过name访问到此按键

（二）按键触发

public class VirtualBtnController : MonoBehaviour,IVirtualButtonEventHandler//通过接口实现点击事件
{
    public VirtualButtonBehaviour[] virtualButtons;
    public UnityEngine.UI.Button[] structureButtons;
    //public UnityEngine.UI.Button[] structureButtonsCT;

    public void OnButtonPressed(VirtualButtonBehaviour vb)
    {
        Debug.Log("Virtual button "+vb.VirtualButtonName+" pressed");

        //BC virtual button function
        if(vb.VirtualButtonName.Contains("BildgeShell"))//通过Name确认点击俺就
        {
            structureButtons[0].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("BottomSlop"))
        {
            structureButtons[2].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("BildgeFloor"))
        {
            structureButtons[1].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("Longitudianal"))
        {
            structureButtons[4].onClick.Invoke();
        }

        //CT virtual button fuction
        if (vb.VirtualButtonName.Contains("DeckBeam"))
        {
            structureButtons[0].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("Floor"))
        {
            structureButtons[1].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("InnerShell"))
        {
            structureButtons[2].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("OutShell"))
        {
            structureButtons[3].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("LongiBH"))
        {
            structureButtons[4].onClick.Invoke();
        }

        if (vb.VirtualButtonName.Contains("TransBH"))
        {
            structureButtons[5].onClick.Invoke();
        }
    }

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

    void Start ()
    {
        foreach(var vb in virtualButtons)
        {
            vb.RegisterEventHandler(this);
        }
    }
}
