Unity3d - Vuforia-Unity: How to enable or disable a virtual button?

回答1:

Guess I found the solution myself!!

For Unity and Vuforia:

Approach #1:

As every entity in Unity is a GameObject, we can find virtual button using approach below:

To enable/disable a virtual button in C# script:

var myVirtualBtn = GameObject.Find("myVirtualButtonName"); // gameobject name above transform settings section
if(myVirtualBtn != null){
    myVirtualBtn.GetComponent<VirtualButtonBehavior>().enabled = true; // Makes touchable virtual btn.
    myVirtualBtn.GetComponent<VirtualButtonBehavior>().enabled = false; // Makes untouchable virtual btn.
}

Approach #2:

Skip registration of event handler associated with your virtual button

VirtualButtonBehaviour[] vbs = GetComponentsInChildren<VirtualButtonBehaviour>();
    for( int i = 0; i< vbs.Length; ++i)
    {
       if(vbs[i].VirtualButtonName != "myVirtualButtonName") // Skip registration
            vbs[i].RegisterEventHandler(this);
    }
