can we add any special effect in GUI.Box like moving gui.box front and back.like wise any special effect is there for gui.box
That can be done...
And you can move the GUI objects around... And they do have Z axis... So:
Look up some stuff on that... So yea, it can, but I don't think that this is how you mean... Best just to do what the video did by making actual 3D objects do the moving... Easier and safer.
Hope this helped!
