how to go to a part of the scene?

I have a house model and I wanted to go to the bathroom by clicking a button or go to the kitchen.

make a empty gameObject at the place where the camera should translate to… then in a script that is attached to the main camera add the following

var _position:Transform;

function OnGUI()
{
  if(GUI.Button("Bathroom"))
  {
       transform.position=_position.position;
  }
}

dont forget to attach the empty gameObject to the _position variable in the editor… Btw modify ur button according to your need from this page
