Need help with constraining position

teobucci1999

hi I'm developing and app and I am trying to do a movement like in cluster hd lite: how can I constrain the position of the touch to the movement of my hero but only in a part of the screen.
I'd like ask you another thing: how can I do the pitch to zoom?
Thanks at all!
