BACK button need to load the previous xml

    Please Help Me

    Iam creating a tour of a 2 level building so so many views in the tour with navigation hotspots.
    The tour is based on different XML files for each view (Eg: location1.xml,location2.xml)

    i need one help from you please.

    i need a back button to the previous view.When a user click on BACK button need to load the previous scene xml.

    How can i do that please help

    Don't know how experienced are but it shouldn't be to complex:
    - using events e.g. onnewscene if not first time loaded copy current_xml to previous_xml, then store current xml name in variable current_xml.
    - Your previous xml will be stored in previous_xml so you can make your back button load it
