Any object can be an interface object

We are not limited to the Unity UI to make interfaces in Unity, and to prove that point, we will use the ball object itself to affect the scene. While we have seen this in the past, this lesson is worth repeating:

2. Select NewScript and type PowerSwitch into the NewScript dialog.

    public GameObject go; 

    void OnSelect() 
    { 

        if(go.activeSelf) 
        { 
            go.SetActive(false); 

        } 
        else 
        { 
            go.SetActive(true); 

        } 

    } 
}

It then calls OnSelect, which is a method called by...
