高通 AR Unity 虚拟按钮

高通开发AR都想用到互动，虚拟按钮互动可以实现虚拟和现实的结合互动。

我使用的版本是vuforia-sampleapps-unity-2-5-8的，具体怎么得到这个看http://blog.csdn.net/liang_704959721/article/details/9201765

     private GameObject mTeapot;
     void Start()
     {
         // Register with the virtual buttons TrackableBehaviour
         VirtualButtonBehaviour[] vbs = GetComponentsInChildren();
         for (int i = 0; i < vbs.Length; ++i)
         {
             vbs[i].RegisterEventHandler(this);
         }

         // Get handle to the teapot object
         mTeapot = transform.FindChild("teapot").gameObject;

      }

     #endregion // UNITY_MONOBEHAVIOUR_METHODS

 //按下
     public void OnButtonPressed(VirtualButtonBehaviour vb)
     {
         //Debug.Log("OnButtonPressed");

         if(vb.VirtualButtonName=="button")
         {
             print("button name!!!");
         }
         if(vb.VirtualButtonName=="buttoon_text")
         {
             print("button_text ");
         }



     }

 //释放
     public void OnButtonReleased(VirtualButtonBehaviour vb)
     {

          if(vb.VirtualButtonName=="button")
         {
             print("button name released !!!");
         }
         if(vb.VirtualButtonName=="buttoon_text")
         {
             print("button_text released");
         }


     }

 }

添加到这个物体上ImageTarget，在添加

注意 virtual Button Behaviour 这个脚本的name就是vb.VirtualButtonName=="button"；

这样就ok了。
