I got ground plane in Unity to work with the basic tutorial  but I don't want multiple instances of my object showing up every time I tap the screen. What I am trying to do is have the object show up automatically when the plane is detected and move to a new plane if it is detected. I want the object be tap-able. 

To test having just one object that can be moved to a new plane and to have a script I could actually edit, I tried implementing the DeployStageOnce script from the tutorial but it didn't seem to work. My object never appeared when I tapped the screen. 

Any thoughts on how to go about getting a tappable object to appear automatically on a plane and move to any plane that is detected? 

Thanks!
